Scientific understanding of food additives

  The history of human use of food additives is as long as the history of human civilization. The use history of food additives in China can be traced back to Dawenkou culture period 6000 years ago. At that time, invertase (sucrase) in brewing yeast was food additive, belonging to food enzyme preparation. More than 2000 years ago, tofu was ordered with "brine". In essence, brine is a food additive and belongs to food coagulant. Recently, food additives have once again attracted attention. In order to help consumers understand food additives scientifically, the following scientific interpretations are made.

  What is a food additive?

  Food additives refer to artificial or natural substances added to food to improve the quality, color, aroma and taste of food and to meet the needs of preservation, preservation and processing technology. Food additives can be produced by chemical synthesis, biological fermentation or natural extraction. There are about 15,000 kinds of food additives approved in the world. At present, there are more than 2,300 kinds of food additives approved for use in China, which are divided into 22 categories according to their functions. The common ones are antioxidants, leavening agents, colorants, preservatives, sweeteners and food spices.

  The use of food additives improves the quality of products, enriches the types of food, and meets the diversified consumption needs of consumers. Without food additives, there would be no modern food industry.Food additives mainly have the following functions:

  one

  Maintain or improve the nutritional value of food itself;

  2

  As an essential ingredient or ingredient in some foods for special dietary uses;

  three

  Improve the quality and stability of food and improve its sensory characteristics;

  four

  It is convenient for food production, processing, packaging, transportation or storage.

  For example, antioxidants are added to edible oil to delay or hinder the oxidation of oil; Colorants are added to candy to give it a good color.

  Rational use of food additives will not affect human health.

  In order to protect consumers’ health, the World Health Organization and the Food and Agriculture Organization of the United Nations have set up a special Joint Expert Committee on Food Additives (JECFA), which is responsible for establishing globally unified principles and methods for food safety risk assessment of food additives, and conducting food safety risk assessment of food additives at the international level. Codex Alimentarius Commission (CAC) has established the international standards for the use of food additives (not mandatory). China, as the host country of Codex Alimentarius Commission on International Food Additives, is in line with international standards, and carries out food safety risk assessment of food additives in combination with the actual production and use of domestic food additives and food consumption data of residents.

  The current National Standard for Food Safety-Standard for the Use of Food Additives (GB 2760-2014) stipulates the principles of use of food additives, the varieties of food additives allowed to be used, the scope of use and the maximum amount or residue.

  The basic requirements that should be met when using food additives mainly include:

  01

  Should not cause any health hazards to the human body;

  02

  Food spoilage should not be concealed;

  03

  We should not cover up the quality defects of food itself or in the process of processing or use food additives for the purpose of doping, adulteration and forgery;

  04

  The nutritional value of food itself should not be reduced;

  05

  On the premise of achieving the expected effect, the amount used in food should be reduced as much as possible.

  Foods that use food additives should be marked on food labels for consumers to clearly understand their consumption. But,Individual consumers are worried that if food additives are added to a variety of foods they eat every day, will it cause the total amount of a certain food additive to be excessive?Is it safe for children and other people to eat food containing food additives?In fact, the food safety risk assessment of food additives carried out in China when setting the maximum dosage of each food additive will consider the situation that people of different ages, regions and sexes eat a variety of foods a day and eat them for a long time. Therefore, the use of food additives in the specified range and dosage will not cause excessive intake and will not cause harm to human health. China has also carried out continuous and dynamic follow-up evaluation of food additives in use, re-evaluated food additives according to the latest research results at home and abroad, constantly adjusted the scope and dosage of use, and banned the use of some substances.

  Food additives are not equal to illegal additives.

  In accordance with the provisions of the Food Safety Law, China has established a series of food additives management systems.

  01

  Before listing

  Implement a strict examination and approval system for food additives;

  02

  Production time

  Implement a production license system for food additive manufacturers;

  03

  When in use

  A food safety risk assessment system for food additives has been established, and more than 700 compulsory national food safety standards have been formulated, covering the use regulations, product requirements, production specifications, labeling and inspection methods of food additives.

  In addition, the requirements for the production, operation and use of food additives, the corresponding supervision and management system, and the import and export management system of food additives have been established.

  Food additives are safe under legal use. Up to now, none of the food safety incidents that have caused harm to human health in China are caused by the legal use of food additives.The illegal acts of "two excesses and one non-violation", such as using food additives beyond the scope and exceeding the limit and adding non-edible substances, are the causes of food safety problems.Melamine is not a food additive in the "melamine" milk powder incident! Sudan red is not a food additive in the "Sudan red duck egg" incident! Formalin is not a food additive in the "poisoned duck blood" incident! It is an illegal additive for food. China’s "Food Safety Law" explicitly prohibits the production and operation of foods that use food additives beyond the scope and beyond the limit; Foods produced with non-food raw materials or foods with chemicals other than food additives and other substances that may endanger human health.Food additives are completely different from illegal additives. Consumers don’t have to avoid food additives deliberately, but should treat them scientifically and rationally.In order to further crack down on the illegal addition of non-edible substances and the abuse of food additives in food production, sales and catering services, a series of special rectifications have been carried out throughout the country. In the past decade, six batches of List of Non-edible Substances and Food Additives that may be added illegally in food have been released one after another. At present, the relevant list is being further improved to ensure the safety of consumers.

Online celebrity is punching in, accelerating the "gourmet desert"?

Original Xiao yin yin ke aesthetics

The summer vacation is coming, and the food raiders have swept the major platforms.

However, there are also some "great rewards for food" gradually.

Among them, Hangzhou, as the representative, was awarded the title of "gourmet desert" because of its special dishes with little merit.

Coincidentally, a debate about what is the real "gourmet desert" in China "swept the country"?

Is online celebrity Punching Cards Destroying Chinese Cuisine?

Recalling the past, the streets and alleys were all famous local snacks, and there were no very magical foods.

Chefs can always improve traditional recipes, handle various cuisines, and always find a family that wants to eat and delicious food in the streets and lanes.

Records about food can always capture the audience’s taste and attract people into the local area.

But I don’t know when it started. "What to eat" and "I don’t know" seem to be a curse that keeps circulating.

Online celebrity’s food punch-in places come and go, and the take-out list can’t be found, and even the fly restaurant has been stripped upside down by netizens.

Eating local specialties on the first day and laughing at McDonald’s and KFC on the second and third day has gradually become the standard for tourists.

Even the documentary about food, it seems, does not have the same dimension-breaking influence as China on the Tip of the Tongue.

With Beijing and Hangzhou as the center, no city can escape the trap of "gourmet desert".

Of course, it’s not that they haven’t tried hard, but they just seem to be on the road of "the harder they work, the sadder they get."

Some time ago, Hangzhou officials also proposed to give no more than 1 million subsidies to the units leading the production of hangzhou dishes.

The shock of the amount has caused many netizens’ chins.

Many cities’ cuisines still adhere to the principle of "takenism", and they will do and hold whatever is popular in other cities.

The little red book and Weibo are also frequently screened by dark dishes.

Lotus hot pot and jasmine tea hot pot that I can’t understand …

Fat intestines and Chili ice cream that are uncomfortable. …

There are also all kinds of dark foods that are "blooming and fascinating".

The official assistance and the food Sao operation initiated by many cities in order to attract people have made the discussion of urban food and food desert rise layer by layer.

This makes people wonder: Is there really no food in China on the tip of the tongue?

Why is food "desertified"?

Do people really have no food to eat?

Obviously, it is not.

The food desert is a food shortage, and now the food is getting more and more satisfactory.

People use eight cuisines to summarize the tastes of different regions, and those cities that have not formed local cuisines and accommodate various tastes are naturally crowned as "gourmet deserts".

After all, everyone doesn’t want to go to the food street in any city, and only grilled squid and stinky tofu are found.

Undeniably, fast food culture has had a great impact on food.

With the acceleration of urbanization, a large number of people have poured into the city, and a large number of catering industries have emerged.

Flowing migrant workers, iron fast food.

Most traditional cuisines have the characteristics of high price and long time, and it is only a matter of time for migrant workers to abandon them.

The Chinese fast food industry has experienced explosive growth in recent ten years. The fast food with porridge, rice and noodles as the main food can better satisfy Chinese’s appetite, and Chinese fast food has become the first choice for many couples’ shops and listed companies.

Fast food restaurants such as Lamian Noodles and Shaxian snack are all over the country.

Routine production process, fast food with fast, convenient and low price as its selling point, has become the choice of many busy urbanites.

Because of busy work, people who are willing to spend four or five hours cooking only exist in Little Red Books and Tik Tok. Coping with a meal is everyone’s general mentality.

When there are enough foods to choose from, eating will change from eating or not to being worthwhile.

It can be said that this is a two-way trip for migrant workers and fast food.

Local specialties in developed cities can’t develop either.

Developed cities like Hangzhou and Beijing are not without local dishes.

However, the development of these local dishes is more and more limited because of their own price polarization and poor taste.

Even some so-called century-old shops are dominated by words such as "unpalatable", "too expensive" and "never come again" on the food platform.

The combination of North-South food culture and chefs’ knowledge of various cuisines has put local cuisine in an embarrassing situation.

Local dishes hidden in the streets can’t get out of the streets at all.

It is difficult for people to experience the delicious taste in ancient poems, because they probably don’t know that the local dishes are simplified versions, which are not the most authentic taste at all.

Besides, Chinese’s taste is getting heavier.

Influenced by Sichuan and Hunan, people all over the country are becoming more and more salty and spicy.

The spicy taste of low-cost hot pot can satisfy the taste buds. Will there be many migrant workers willing to spend a lot of money to eat Longjing shrimp quietly?

At the same time, for most people, a major reason for the food desert is that they can’t find the memory of taste buds in other places.

Countless strangers are crowded in a city, and their food requirements may be more critical.

People’s definition of delicious food often comes from the taste they ate when they were growing up.

In this process, they gradually formed an understanding of "local authenticity". Unless it meets this standard, it is not authentic.

Food desert, really can’t be saved?

Who can save the deformed food circle?

Online celebrity cuisine, with its short and dazzling existence, has become a hot topic in people’s mouths.

People are scrambling to taste exotic foods, take photos with their mobile phones and eagerly upload them to social media.

The restaurant environment and the shape of the dishes affect people’s choice of eating.

These online celebrity delicacies, which often have amazing appearance and attractive production process, have aroused widespread concern and sharing.

With its unique appearance and colorful colors, it quickly became popular on the Internet, attracting a large number of diners who pursued novelty and excitement.

However, the popularity of these foods is not based on respect for traditional cooking skills and tastes, but aims at catering to the instantaneous visual impact and taste stimulation of the public.

When a kind of online celebrity cuisine has not had time to take root in the hearts of the public, another novel and attractive cuisine has quietly taken its place.

This rapid upgrading makes the fast-growing and fast-dying food unable to stay in people’s memory for a long time.

Although online celebrity cuisine has brought novelty and excitement to people, it often lacks real quality and depth.

It takes a lot of energy and time to build a gourmet culture.

For Chinese, eating is a kind of life and culture.

Song Saoyu Soup, Dongpo Meat, Puffed Meatballs and West Lake Vinegar Fish, the story of China for thousands of years has been spread behind a dish, and all the feelings of rivers and lakes and human history have been integrated into the dish.

What I ate was not food, but Chinese’s feelings and romance.

The skillful cooking process at the beginning of eat drink man woman captured the hearts of many audiences.

Qing Qing Daily also emphasizes regional culture and gourmet culture through the selection of Jiuchuan.

If diners don’t pay attention to the season and temperature of food, it is not surprising that the chef will spoil it.

Real food should stand the test of time and inherit the essence of culture.

Food must be appreciated by both diners and chefs to produce the most extreme taste.

Food has never been desert, but it is just a heart to eat and dishes that can’t go out.

The enthusiasm of ice and snow "does not close" Hebei continues to write a new chapter in the development of the post-Winter Olympics era

Late days, autumn waters are pale. The sun sets on the mountainside, and the geese set in the sun.

Walking into Malan Village, which is located in the deep mountain area in the west of Nanzhuang Town, Fuping County, Hebei Province, following the beautiful singing, stepping on the steps of "Music Castle" and climbing up the stairs, the Greek song Ode to the Olympics is from far to near, and suddenly, it seems to cross the opening ceremony of Beijing Winter Olympics.

Through the door, Yang Zirui, a member of Malan Children’s Choir with ponytail, attracted everyone’s attention with her sweet and confident smile. "By participating in the opening and closing ceremonies of the Beijing Winter Olympics, I have changed a lot, enhanced my self-confidence and loved my hometown more. I want to integrate the fighting spirit of the Beijing Winter Olympics into my study and life in the new semester and strive to do my best in all aspects. " In the fifth grade, she is looking for her own love, taking into account vocal music and dance training while not relaxing her study.

Accompanied by bursts of singing and going to Qiu Lai in the spring, the Beijing Winter Olympics has become a beautiful stroke in the historical picture. However, on the land of Yanzhao, this grand event has injected a powerful impetus into the development of Hebei, which lasts forever.

"The Hebei Provincial Sports Bureau issued the Implementation Plan for Accelerating the Post-Olympic Economic Development, proposing that by 2025, the total scale of the sports industry in the province will reach 300 billion yuan, and the total scale of the ice and snow industry in the province will reach 150 billion yuan. The development of ice and snow tourism and ice and snow equipment manufacturing has achieved remarkable results. Zhangjiakou’s’ Winter Olympics City’ brand is prominent, and Chongli will become an international gathering area for high-end ice and snow sports and leisure resorts." Li Qi, director of the Economic Department of Hebei Provincial Sports Bureau, said that it is necessary to implement the post-Olympic mass ice and snow sports promotion campaign, incorporate the knowledge and skills of ice and snow sports into the school teaching content, and incorporate roller skating and skating into the provincial, city and county college and middle school sports meetings.

From "one season" to "four seasons", all-season operation boosts the extension of industrial chain and promotes development

In Chongli District, Zhangjiakou City, located in the north of Hebei Province, the cries of the Beijing Winter Olympics are fading away, but time can’t take away the people coming and going here and the excitement is extraordinary.

The recently concluded Rock Sheep Cup Taiwu Mountain Bike downhill Invitational Tournament and GDL Mountain Bike Series Beijing-Tianjin-Hebei Station were held in Taiwu Holiday Town in Chongli District. Players from Beijing and other places released their sports passion in the autumn valley.

"This summer, we launched mountain cross-country races, bicycle downhill races, frisbee competitions and other activities, which attracted tourists from Beijing, Tianjin and Hebei around Beijing. The number of passengers in Taiwu exceeded 12,000 in a single day, and it was difficult to find a room on weekends." Li Yongtai, executive vice president of Taiwu Ski Town, Chongli District, Zhangjiakou City, said that the recovery of the holiday tourism market not only brought vitality and confidence to enterprises, but also brought tangible benefits to local people.

Chongli is famous for its ice and snow. As more and more people come to worship the ceremony and feel it, the unique ecological charm here has been further highlighted. On the basis of making ice and snow tourism bigger and stronger, Chongli District continues to expand the development space of cultural tourism industry, creating a four-season tourist attraction of "spring with flowers and autumn with moon, summer with cool breeze and winter with snow, and when it comes to Zhangjiakou, it is a good time for the world".

"The average temperature in summer is 18.4 degrees Celsius, and it is blue sky and white clouds almost every day. You don’t need to turn on the air conditioner when you sleep at night, you can breathe deeply when you open the window, and there are many projects suitable for parent-child travel, which is the best summer resort! " Ms. Wang’s family from Shijiazhuang City, Hebei Province talked about the trip to Chongli and felt a lot.

Starting from Chongli District, all the way to the south, in Qishan Ski Resort, Laiyuan County, Baoding City, the snowy road covered with silver in winter is now green and blue.

Different from Chongli’s "winter tour" to "four seasons tour", Laiyuan County changed "summer tour" to "four seasons tour". With the successive establishment of new tourism formats such as Laiyuan Huazhong Hot Springs and Qishan Ski Resort, the county has formed a comprehensive tourism experience holiday circle of "climbing Baishiqi Mountain, skiing Qishan Powder Snow, soaking in mineral hot springs and enjoying the lantern festival by the lake".

"Youjian Inn" is a boutique hotel, located in Laiyuan County. According to the boss Zhao Donghai, the number of rooms booked this summer is large, and it is almost full every day. Now he is cleaning up the yard and room of the inn to get ready for the winter tourist season.

"Now the snow-making scale of Qishan Ski Resort has reached 700,000 square meters, and there are 16 primary, intermediate, advanced and characteristic ski trails. It has a four-season platform group and a ski platform wind tunnel laboratory, which is convenient for national athletes to train here. " Wang Xiaohu, president of Qishan Ski Resort, said.

Changing to all-season operation is an important step to inject momentum into economic development. This year, Qishan Ski Resort has also planned and developed summer and autumn tourism projects with high standards, and set up sections such as research, competitions, mountain sports, recreation and vacation, medical care and health care, and mass leisure. "The hosting of the Beijing Winter Olympics has made more people understand the ice and snow sports and feel the charm of the ice and snow sports." Wang Xiaohu said, "We will continue to explore how to extend skiing in winter to the four seasons, meet the needs of more beginners and enthusiasts, and help the ice and snow industry develop continuously with high quality."

From "Cold" to "Hot", Beijing Winter Olympics leads the ice and snow movement into thousands of households.

With the arrival of the Beijing Winter Olympics, the seeds of ice and snow sports can be spread all over Hebei. After the Beijing Winter Olympics, these seeds began to take root, sprout, blossom and bear fruit in Yanzhao.

As a well-known local roller skater in Laiyuan, Li Sihan, a student of No.1 Primary School in Laiyuan County, Baoding City, participated in the speed roller skating competition of the Second Ice and Snow Games in Baoding City in 2020, and won three championships of 300 meters, 500 meters and 3000 meters in Junior Women’s Group B. At the 3rd Ice and Snow Games in Hebei Province in 2021, Li Sihan won the third place in the 1500m junior group of provincial speed skating …

And this, thanks to the ice and snow movement vigorously implemented by the first primary school in Laiyuan County into the campus infrastructure project. The school insists on the combination of going out and introducing, actively organizes physical education teachers to go out for training and study, and hires professional coaches from the county roller skating association to guide the school. At present, the school has set up a number of sports teams, such as roller skating, skiing, ice cuqiu, land ice hockey and curling, and trained many potential young ice and snow sports seedlings to enter Baoding City Team and Hebei Province Team.

By the end of 2021, there were 47,000 registered young athletes in Hebei Province. Since July this year, Hebei Provincial Sports Bureau, in conjunction with the Provincial Department of Education, has organized a new year’s training for ice and snow sports teachers in primary and secondary schools. This year, there will be 6,000 physical education teachers in primary and secondary schools in Hebei Province, who will be trained in ice hockey, land curling, roller skating and speed skating in batches. Up to now, 20 sessions and 5,000 people have been trained. At the same time, Hebei Province also launched the roller skates plan for rural primary and secondary schools in the new year, and arranged 5 million yuan for the procurement and distribution of roller skates for rural primary and secondary schools. Now the procurement plan has been submitted for approval.

Into the campus, into the enterprise, into the family, into the community, into the countryside, into the office … Now, the ice and snow movement has gradually broken the geographical and seasonal restrictions and entered thousands of households, becoming a new lifestyle-

Relying on the Ice and Snow Association and the Ice and Snow Sports Club, Xingtai Sports Bureau invited high-level talents to teach, organized 22 training courses for social sports instructors for physical education teachers and ice and snow sports enthusiasts, and trained more than 800 second-and third-level social sports instructors for ice and snow projects, enriching the team of social sports instructors for ice and snow, and becoming practitioners and guides for the masses to participate in the real ice and snow sports;

Zhangjiakou City has held 759 ice and snow events such as Beijing-Tianjin-Hebei Ice Hockey League, Speed Roller Skating City League and Cross-country Pulley Challenge this year.

Cangzhou City has deeply integrated local folk customs, traditional projects and ice and snow elements, and launched special activities such as Wuqiao ice acrobatics, ice dragon dance in Canal District and ice lion dance in Cangxian County to create a highlight of ice and snow sports. Since this year, more than 700 ice and snow events have been held …

"On the basis of building 202 indoor skating gymnasiums and 62 ski gymnasiums, we will strive for the support of central financial transfer payment funds." Ma Jinliang, director of the Mass Sports Department of Hebei Provincial Sports Bureau, said that Hebei Province will continue to build a movable ice rink this year, and will also pilot the construction of 14 ice and snow sports experience and training centers to make it more convenient for people to participate in ice and snow sports.

The transformation from "Stadium" to "online celebrity" Stadium empowers the high-quality development of Hebei sports.

Boarding the summit club of the National Ski Jumping Center (also known as "Snow Ruyi"), the whole venue is surrounded by green mountains and green mountains, and the rolling mountains meet the blue sky, which is refreshing. Many tourists come here specially to take photos with this unique venue.

On July 16th this year, the launching ceremony of the 2022 (2nd) Beijing-Zhangjia All-season Sports Tourism Carnival and the opening ceremony of Zhangjiakou Chongli Olympic Park were held in "Xueruyi", which marked the official opening of Zhangjiakou Winter Olympic Stadium and its post-game operation.

As the landmark of Beijing Winter Olympics and the new landmark of Zhangjiakou City, "Xueruyi" has become the punching place for summer tourism "online celebrity". "The peak period of tourists is from July to August, and the cumulative number of visitors since the official opening of the park has exceeded 50,000." Ji Jiajiao, manager of the operation and development department of Zhangjiakou Olympic Sports Construction and Development Co., Ltd. said.

It is understood that taking the world-class "sports and cultural tourism" as the integration destination, according to the preliminary operation plan, the National Platform Skiing Center will build a modern science and technology complex-the Summit Club, including the top exhibition venue, the quality performance venue and the top ceremony venue, the sports cultural goods living museum, the sports theme technology experience area and the Olympic culture exhibition area; Create the online celebrity sports punch card area-slide area and stand area, add the platform skiing function in summer while retaining the platform skiing function, and develop it into an adventure sports playground on weekdays; Create the entertainment and experience commercial streets in front of the museum-Ruyi Square and Ice Yuhuan, and carry out activities such as parent-child entertainment, vacation and leisure, echoing the ruins of the Great Wall from a distance, and creating a "romantic residence at the foot of the Great Wall".

The beautiful environment makes people linger, and convenient transportation is within reach. "The most seen vehicles here are Beijing brand vehicles. The straight-line distance from here to Beijing is only 150 kilometers, and it takes only 2 hours to drive along Jingli Expressway." Ji Jiajiao said that the shorter time is the Beijing-Zhangjia high-speed railway, which is about an hour’s drive. Many Beijing tourists come to "punch in" and also inject new impetus into building the Beijing-Tianjin-Hebei tourism circle.

The gorgeous turn of the Winter Olympics venues has produced more new formats, and it has also continuously empowered the sports industry in Hebei Province to take a new step in the post-Winter Olympics era.

This year, Hebei Province issued the "Implementation Plan of Hebei Province’s" Three-year Action Plan for Sports Industry Upgrading "in 2022", which proposed to speed up the construction of the Beijing-Zhangjia sports and cultural tourism belt and vigorously develop the post-Olympic ice and snow industry. On July 15th, 2022, the Beijing-Zhangjia Sports and Cultural Tourism Belt Development Summit was held at the National Platform Skiing Center in Chongli District, Zhangjiakou City.

Not only that, this year, Hebei Provincial Sports Bureau, together with Beijing-Zhangjia Sports and Cultural Tourism Department, launched 118 "All-season Sports Burning Beijing-Zhangjia" sports brand events, and launched 52 excellent sports tourism projects, including "Top Ten Excellent Sports Events", "Top Ten Sports Tourism Routes", "Top Ten Sports Tourism Destinations" and 22 "Beijing-Zhangjia Sports Research Destinations".

Now, Hebei is vigorously developing the post-Olympic economy and cultural and sports tourism industry, making it a new kinetic energy to promote development. In the next step, Hebei Province will closely focus on the follow-up efficient and scientific utilization of the Winter Olympics venues, actively undertake professional high-end competition training, promote the expansion and extension of the venues to comprehensive functions such as sports, culture, leisure and entertainment, and living and recreation, attract more tourists into Hebei, continuously increase the scale of groups who regularly participate in real ice and snow sports, consolidate and enhance the achievements and quality of "30 million people participating in ice and snow sports" in the province, and continue to write a new chapter in the development of the post-Winter Olympics era.

The dog days are coming! Meteorological data tell you how hot the weather has been recently.

Expert consultant:

Yuan Yuan, Chief Duty Officer of National Climate Center in Flood Season.

After entering the light summer solar term on July 7, it ushered in the first stage on July 16, and we are about to face the test of "steaming up and cooking down" in the dog days. Since mid-June, many places in China have started the high-temperature "roasting mode" ahead of schedule, and many cities have experienced high-temperature weather above 40 C. Meteorological data tell you how fierce this wave of high temperature is.

How hot is it this summer?

-There are 71 national weather stations that have broken through historical extremes.

Since June 13th, China has experienced the first regional high-temperature weather process this year, and many places have continued to experience high temperature and summer heat. The Central Meteorological Observatory has issued high-temperature warnings for several consecutive days.

As of July 12, the high temperature event has lasted for 30 days, covering China’s land area of 5.021 million square kilometers and affecting more than 900 million people. The average number of high temperature days in China reached 5.3 days, 2.4 days more than normal, the highest in the same period since 1961. Among them, the number of high temperature days in most parts of East China, Central China, Northeast Southwest China, southwestern Shaanxi, southwestern Shanxi and southern Xinjiang is 5 to 10 days more than normal. The number of high temperature days in northwestern Jiangsu, northern Anhui, most of Henan, northwestern Hubei, southeastern Shaanxi and northeastern Chongqing is more than 10 days than normal.

Since June, the daily maximum temperature of 238 national meteorological stations in Hebei, Henan, Tianjin, Yunnan, Sichuan, Zhejiang, Xinjiang and other places has exceeded the monthly extreme value, and the daily maximum temperature of 71 national meteorological stations has exceeded the historical extreme value. Among the top ten stations with high temperature values, the daily maximum temperature in Lingshou, Hebei (44.2℃, June 25th), Gaocheng (44.1℃, June 25th), Zhengding (44.0℃, June 25th) and Yanjin, Yunnan (44.0℃, July 11th) exceeded 44℃. The daily maximum temperature in Lanzhou, Gansu (37.6℃, June 24th), Yinchuan, Ningxia (37.2℃, June 16th), Tianjin (40.1℃, June 25th) and other provincial capitals or municipalities directly under the central government exceeded the monthly maximum. Shanghai Xujiahui Station not only had the earliest high temperature of 40℃ on July 10th, but also reached 40.9℃ at 14: 30 on July 13th, tying the highest temperature record since the local meteorological record (1873).

June 25th is the day with the largest number of high temperature extreme stations since June, in which the daily maximum temperature of 28 stations exceeded the historical extreme value, and the top ten stations with daily maximum temperature all appeared in Hebei.

According to the monitoring index of regional high temperature process, considering the influence scope, intensity and duration of high temperature events, the comprehensive intensity of this event is the sixth strongest since 1961, second only to 2013, 2017, 2003, 1966 and 2019. Since 2000, the typical years of large-scale sustained high temperature events in China are 2003, 2013 and 2017. Generally speaking, this year’s high temperature event started earlier than the above three years, and the duration and the number of historical extreme high temperature stations are not as good as these three years. Although the influence scope and the maximum temperature of a single station are not as good as 2017, they have exceeded 2003 and 2013.

Early warning data can also show the "off the charts" degree of high temperature. Since June (as of July 13th), except Heilongjiang and Liaoning, 29 provinces (autonomous regions and municipalities directly under the Central Government) have issued 15,008 high-temperature warnings, including 1,869 red warnings, 8,931 orange warnings, 4,122 yellow warnings and 86 blue warnings. Among them, the number of high temperature warnings issued on July 10 was the highest, with 857. Henan, Hunan, Shaanxi, Hebei and Sichuan are the provinces that issue the most high-temperature warnings. The top ten provinces that have issued high temperature warnings for the longest time in a row are Henan (31 days), Xinjiang (20 days), Anhui (19 days), Shaanxi (17 days), Sichuan (17 days), Shanxi (13 days), Gansu (13 days), Hebei (12 days), Jiangsu (12 days) and Yunnan (12 days)

From June 1st to July 13th, the top five provinces of high temperature warning release data source: National Early Warning Information Release Center.

 The northern hemisphere suffered a "heat wave"

-Extreme high temperatures are hitting many parts of the world.

Extreme high temperature weather is continuing around the world, and high temperature heat wave events spread in Europe, East Asia and North America, and the highest temperature at the same time exceeded the historical extreme.

In mid-June, Europe generally suffered from high temperature and heat waves. On June 10th, hot weather began to appear in Portugal. On the 13th, the temperature in central and southern Spain has exceeded 40℃; On the 18th, the highest peak of this round of high temperature weather occurred in France. As many as 70 provinces issued high temperature warnings, and high temperature records in many places were broken. On the 19th, a record high temperature occurred in Germany, and a forest fire broke out in Brandenburg, forcing about 620 residents to evacuate.

In mid-June, record high temperatures spread from the Great Plains of the United States to the Mississippi Valley and the southeast. More than 125 million people in most States in the central and eastern United States are under high temperature warning, which is more than one third of the population of the United States.

On the afternoon of June 25th, the temperature in Isezaki, Gunma Prefecture, Japan reached 40.2℃, the highest temperature in June since Japan had meteorological records.

Why is the high temperature so fierce and strong?

-Global warming and abnormal atmospheric circulation are the main causes.

The sixth assessment report of the United Nations Intergovernmental Panel on Climate Change (IPCC) points out that global warming is happening at an unprecedented speed since 2000 in the last 50 years, and the instability of the climate system is increasing. UN Secretary-General antonio guterres called it a "red alert for all mankind". Global warming is the climate background of frequent high-temperature heat waves in the northern hemisphere, and abnormal atmospheric circulation is the direct cause of frequent high-temperature heat waves in many places around the world since June this year.

Since June this year, over the northern hemisphere subtropical zone, the western Pacific subtropical high zone, the Atlantic high zone and the Iranian high zone have all been enhanced in stages, thus forming a large-scale global warm high zone. Under the control of warm and high-pressure belts, the prevalence of downward flow is conducive to the ground warming. In addition, under the action of a wide range of high-pressure belts, the air is relatively dry and it is not easy to form clouds, which also makes solar radiation reach the ground more easily, leading to frequent high temperatures and strong intensity, which in turn leads to persistent high-temperature heat waves in many places in the northern hemisphere.

Specific to China, the ongoing La Ni? a event has provided an important climatic background for the occurrence and development of high temperature in the south since June this year, especially in July, when the development of the mid-latitude warm and high pressure belt strengthened, resulting in a large-scale high temperature weather. According to statistical analysis, in the summer following most La Nina events, the western Pacific subtropical high (referred to as subtropical high) tends to be northward. Since late June this year, the subtropical high has moved northward, especially after Typhoon Siam moved northward in early July. The subtropical high has been extended westward, and the Iranian high has been extended eastward. Combined with the mid-latitude continental high, a stable warm and high pressure zone has been formed over China, which has caused a wide range of high temperature weather. In addition, due to the water vapor carried by the subtropical high, the humidity in the central and eastern regions of China is relatively high, which makes the human body temperature higher.

Compared with previous years, since July this year, the Iranian high has been extended eastward to form a huge warm high pressure belt with the western Pacific subtropical high and the mid-latitude continental high, which is rare in history. Historically, high-temperature heat waves occurred in Jiangnan, South China, Sichuan and Chongqing due to the extension of subtropical high to the west, or high temperatures continued in northwest China and Xinjiang due to the stable maintenance of continental high. Therefore, this year, the high temperature range is relatively large, the duration is long, and the extremes are also prominent.

From June 1 to July 12, the number of high temperature days in many places in China exceeded 30 days. Source: National Climate Center.

The high temperature will continue

—— Do not treat health protection in production and life lightly.

According to the forecast of the Central Meteorological Observatory, as of July 26, there will be many hot weather in southern China and other places. From July 13th to 16th, it was hot and rainy in Sichuan Basin, Shaanxi Guanzhong, Jianghan, Jianghuai, Jiangnan and South China. From 17th to 20th, there will be rain in Sichuan Basin, Jianghan, Jianghuai, the western and northern parts of the south of the Yangtze River, and the northwestern part of South China, and the high temperature weather will be alleviated, while the southeastern part of the south of the Yangtze River and the eastern part of South China will continue to be hot and muggy. After the 21st, the high temperature in the south will develop again, and the scope will be expanded.

The National Climate Center predicts that from July 27 to August 11, the temperature in most parts of China will be higher than normal, and the temperature in western Inner Mongolia, Shanghai, Jiangsu and northern Zhejiang will be 1℃~2℃ higher, which may lead to a long-lasting high temperature weather process.

High temperature weather will have a great impact on power supply, people’s production, life and health. The public should try to avoid outdoor activities at high temperature, and shorten working hours when working at high temperature. We should pay special attention to heatstroke, prevent, identify and treat it early, especially for the old, weak, sick and young people. Attention should also be paid to the safety of electricity consumption in hot weather, and the power sector should respond to the deployment in advance to prevent the supply shortage and fire hazards caused by the surge in electricity consumption and excessive power load.

The daughter was admitted to the university because of the aid project. The Xinjiang man rode Wan Li to thank him.

  Li Zhiyuan rested on the way to feed the horses.

  Enter the urban area of Lianyungang and be escorted by the police.

  Schools aided by Lianyungang.

  Li Zhiyuan, a 38-year-old from Kaigan Community, Mohur District, Horgos, Xinjiang, has traveled more than ten thousand miles from the terminal of Lianhuo Expressway at Horgos Port. Yesterday, he finally arrived in Lianyungang, the east bridgehead of the New Eurasian Continental Bridge.

  Li Zhiyuan, who just jumped off his horse, told Zi Niu news reporter that he "tossed" all the way to Lianyungang this time, one for gratitude, and the other for riding "slowly" in China to see the great rivers and mountains and beautiful scenery of the motherland.

  Lianyungang aided the school, and his children benefited. He must personally send a banner and thank you.

  On an empty meadow in Baita Town, Donghai County, Lianyungang City, Zi Niu news reporter saw Li Zhiyuan and two dark horses carrying him for 5,000 kilometers. "This one is my mount, and the other one is used to carry luggage. It is about to enter the city." Li Zhiyuan said with a smile.

  "I rode to Lianyungang this time and wanted to send two banners to the Lianyungang municipal party Committee and municipal government. Thank them for their aid to Horgos for so many years. My eldest daughter, Li Huimin, just graduated from Sugang Middle School and was admitted to the university. My five-and-a-half-year-old son, Li Yuxin, is in a large class at Horgos Gegan Garang Axi Kindergarten. This time I am here to thank the Lianyungang Municipal Party Committee and Municipal Government! " Li Zhiyuan’s dark face is full of sincerity.

  Su Gang Middle School in Li Zhiyuan’s mouth was formerly Horgos Port Middle School. Lianyungang participated in the aid construction of Sugang Middle School, which was officially opened in September 2013. In 2014, a high school was established and the first high school students were enrolled.

  Li Zhiyuan’s daughter was admitted to Changji Vocational and Technical College in Xinjiang from Sugang High School. The Gegan Garang Axi Kindergarten he mentioned is also one of the 10 bilingual kindergartens aided by Lianyungang in Horgos.

  Zi Niu news reporter learned that in August 2014, Lianyungang Education Bureau sent seven teachers to Sukang Middle School in Horgos City to teach for one year, which solved the problem of insufficient teachers for junior high schools.

  The vice-president of Jiangsu Port High School’s aiding Xinjiang told Zi Niu news reporter that Lianyungang City also sent a large number of excellent teachers to teach in Jiangsu Port Middle School, which brought the concept and mode of school teaching management in Jiangsu into middle schools, and the quality of education and teaching in local schools has been significantly improved.

  This year, Sugang High School welcomed eight teachers who helped Xinjiang in the ninth session. They founded Lianyungang Class in the first and third grades of high school, which had a great influence on students’ learning.

  At present, there is only one high school in Horgos, Su Gang Senior High School, with 784 students, 91 faculty members and 21 classes. In 2019, there were 198 candidates who took the college entrance examination, 56 of them were online, the online rate was 28.5%, and 19 of them scored above 500. The school ranked among the top high schools in counties and cities in Yili.

  Li Zhiyuan told Zi Niu news reporter that his children have benefited from Lianyungang’s aid to Horgos for so many years. Li Huimin is a student who just graduated from Sugang High School this year. Zi Niu news reporter learned from the teacher that Li Huimin usually studies hard and practically. "He is a very good child." The news that Li Zhiyuan rode his horse from Horgos to Lianyungang to send the pennant this time also touched many teachers in the school. Zeng Baoshan, a former principal of Horgos Sugang Middle School, said that he was surprised by his father’s actions and was deeply moved by his persistence. The changes brought by education are not only reflected in the achievements, but also infected the ardent hearts of every child and parents.

  Li Zhiyuan said that because of this, his idea of riding to Lianyungang to send a pennant became stronger and stronger. After four years of consideration and preparation, with the support of relatives and friends, he embarked on a journey on April 27th this year.

  Pain & Gain

  Wan Li sent a banner, and it was hard to get support from family and community.

  From Horgos to Lianyungang, we have to cross many provinces and cities such as Gansu, Inner Mongolia, Beijing and Jiangsu, and pass through many no-man’s land, which is full of dangers along the way. For Li Zhiyuan, this is his first trip.

  At first, Li Zhiyuan’s father thought that it was not a matter of a few days for his son to ride to Lianyungang, and it would take at least half a year to get there once and for all. He didn’t trust or understand. However, when he learned that his son had made a report with the community branch to the relevant departments at the higher level, and also wrote an application with the public security department, he was relieved.

  Li Zhiyuan’s wife, Dan Yulan, told reporters on the phone that at first Zhiyuan said that he was going to Lianyungang. She didn’t know where Lianyungang was, but it was good to think that her husband had been in this ravine all his life, so she supported her husband’s idea. Now that people have arrived in Lianyungang safely, she has nothing to worry about.

  Li Zhiyuan never reported good news but not bad news when talking to his family. When it comes to her father’s feat, Li Huimin, the eldest daughter, is very proud: "Dad should have worked very hard all the way, but he did a very meaningful thing. He set a good example for us and I am proud of my father."

  Liu Yanchun, secretary of the Party branch of Kaigan Community in Mohur District, told Zi Niu news reporter that Lianyungang has given great support to Horgos in recent years, especially the construction of Su Gang High School in Horgos, where Li Zhiyuan’s children are located, and they have been admitted to the university as expected this year. He sent a banner to the Lianyungang working group, which is also the simplest expression of residents in Kaigan community.

  In order to ride a horse, I walked more than 1000 kilometers and gained friendship and touch in more than 140 days.

  Li Zhiyuan said that it is more than 4,000 kilometers from Horgos to Lianyungang if driving normally, but he has to find a place with grass and water when riding, and he has to walk around frequently, so it takes nearly 1,000 kilometers more than driving normally. At his speed, he walks five or six kilometers every hour, rides eight to ten hours a day, and travels about 60 kilometers a day at most.

  Wan Li trip, although hard, but also moved. On June 1st, he went to a desert Gobi Desert in Dashitou Township, Mulei County, Changji Prefecture. After two horses ate the weeds on the roadside, they suddenly started to slobber and shook their heads, and then they couldn’t walk. It turns out that the kind of weeds that horses eat are called inebriated weeds, also called poisonous weeds. Ma Jianguo, an enthusiastic local villager, not only helped Li Zhiyuan watch the horse, but also instructed him to go to a pharmacy 50 kilometers away to buy an antidote. After three or four days in Majian country, the horse’s condition gradually improved. Before he left, Li Zhiyuan thanked him for paying, but the other party didn’t want any money.

  经过哈密市巴里坤哈萨克自治县大河镇干渠村时,李志远突然接到妻子的电话,说她母亲病重让他抓紧返家。他把两匹马托付给当地一位考姓村民,并掏出一沓钱交给这位考大哥,结果考大哥说,“你要是给钱,就把马儿牵走,我不帮你照看了。”

  李志远匆忙买票返回霍尔果斯,回家后老人第四天就因病不幸去世,他过了岳母的头七后才买票返回考大哥家中,继续他的行程。

  一路下来,李志远觉得最大的收获就是收获了友情和感动,每到一个地方总有热心村民免费给他和他的马儿送吃的送喝的,什么都有,牛肉干、月饼、矿泉水,还有村民自家腌制的咸菜。

  行程继续

  带着母亲的遗愿 去天安门看升国旗

  今年38岁的李志远,从小就是一个孝顺的孩子,由于妈妈生前一直有一个愿望,要去北京天安门广场观看一次升国旗仪式,但是直到倒下也没能如愿。

  李志远告诉紫牛新闻记者,他妈妈糟兰香生于1959年,1998年加入中国共产党,生前一直是霍城县莫乎尔牧场开干村卫生室的一名村医。2011年9月11日,因连续多日带病奋战在脊髓灰质炎强化免疫工作一线,不幸因公殉职。

  李志远说,他在十几岁的时候,就曾听妈妈说她想去北京天安门广场,观看一次升国旗仪式。但是她平时工作太忙了,一直没有时间去,直到这次他打算给连云港市委市政府送完锦旗后,从连云港直接骑马转道北京,替母亲在天安门广场前观看一次升旗仪式,他预计11月初才能到达北京。

  昨天,李志远骑着马还没进城便引起市民围观,连云港市交警支队获悉后,立即派出三辆警用摩托车为李志远护航。连云港市援疆办南方处长表示,他得到消息后,立即将此事向连云港市委办、市政府办进行了汇报,并妥善接待了李志远,将其两匹马安置在新浦公园动物园里的笼舍,由公园饲养员照料。

  连云港市新浦公园管理处主任苗学勇介绍,李志远的两匹马经历了5000多公里行程,非常疲劳,昨天下午到达之前,饲养员已经把笼舍打扫好,并进行消毒,接下来该园将精心照料。

  采访结束前,南方告诉紫牛新闻记者,18日9点半,连云港市委办和市政府办相关人员将在市政府南广场举行相关的接收锦旗仪式。(紫牛新闻记者 张凌飞 见习记者 艾陆琦 )

Record the whole process of 2009 Fox upgrade calibration software.

  On May 31st, 2010, it was officially announced that 236,643 09 models would be recalled due to the possibility of flameout at low speed. In this matter, we contacted Changan Ford according to the recall maintenance items that netizens are concerned about and the problems that need time and later use, and recently went to a 4S shop in Changan Ford in Beijing to make a full report on the handling method of Fox recalled vehicles, and consulted with the after-sales staff in the store. In the following, I will give you a detailed report.


Home of the car


  This recall of’ 09 Focus will mainly upgrade the version of PCM electronic control program for vehicles to improve the problem of flameout under low load. TCM (Transmission Computer) system will also be upgraded for automatic transmission models to improve the unstable speed when parking or starting.


I. Record of relevant data before vehicle maintenance


  From the discussion in the current domestic auto forum, we know that Fox owners are mainly concerned about whether they will increase the idle speed of vehicles to control the flameout when upgrading the calibration software. Will fuel consumption increase? This time, the editor dedicated his own car (09 Focus 1.8AT models produced in March 2010 within the scope of recall) to do this "meat cutting test".


Home of the car


  The above picture shows the idling situation of parking P gear before upgrading before entering the repair shop. It can be seen from the picture that before the upgrade, it was 800 rpm.


Home of the car


  From the signboard on the left side of the vehicle, you can see the owner registration information reserved every day. According to what we learned from the after-sales staff of the 4S shop, it is necessary to wait until the end of July for the recall. In addition, when asked about the process to be handled in the recall, the after-sales staff said: We will clean the recalled vehicle festival first, and then upgrade the calibration software. It is estimated that the whole process will take one and a half hours.


Home of the car


  After entering the maintenance workshop, the basic inspection of the vehicle should be carried out first, such as whether the lights are on normally, the chassis situation and the basic inspection of the engine.


Second, the maintenance process records


1. Clean the throttle valve


  When the technicians began to deal with the faults of the recalled vehicles, we first recorded the starting time of the whole process: 16: 05pm.

First of all, according to the process, to clean the throttle, the technician is removing the throttle.


Home of the car


  As can be seen from this picture, the removed throttle has a thick yellow layer. (Little knowledge: Too much carbon deposit in the throttle will affect the intake efficiency and normal combustion effect, thus causing problems such as unstable idle speed of the vehicle, weak acceleration of the vehicle, increased fuel consumption and slow response of the throttle. )

  To start cleaning the throttle, we need to use a special throttle cleaning agent. According to our knowledge and technicians, we need to use half a bottle of cleaning agent every time and dry it with a cleaning cloth.

  When the throttle cleaning is finished, record the completion time of throttle cleaning: 16: 22pm. Judging from this time, it takes 17 minutes to clean the Fox throttle.

Professor Li Zhuofen’s speech: How to spend all the hardships in the "epidemic" environment

Professor Li Zhuofen's speech "How to spend all the hardships in the" epidemic "environment" (photo source: Fenghuang. com Buddhism)

The following is a transcript of the speech:

Moderator Zeng Yiyi:Hello everyone! I’m Zeng Shuyi, the host of Phoenix Satellite TV, and welcome to the 12th lecture on Buddhist culture of the 6th Guanyin Cultural Festival, "How to spend all the sufferings in the epidemic area". We all know that life is bitter, but in this COVID-19 epidemic, people feel different levels of suffering. There is the fear of death after being infected, the pressure of fear of being infected to others after being diagnosed, and the fact that the epidemic has affected work, so how can we get through the pain of the immediate predicament? This kind of physical suffering and mental suffering is particularly obvious in this epidemic.

It has been a whole year since the outbreak of the COVID-19 epidemic. Over the past 300 days, we have encountered the greatest threat in our lives, that is, the troubles that Covid-19 has brought to human life and life. Although for thousands of years, human beings have been suffering from various disasters in heaven and earth, as well as epidemics, but we have spent it again and again, but human beings are forgetful. And this epidemic for us, what do humans remember? How to spend all the misery? Now, let’s invite Mr. Li Zhuofen, academician of China Academy of Engineering, former vice-president of HKU and professor of lectures, to give us a lecture today on "How to spend all the hardships in an epidemic area", and please welcome the president.

Professor Li Zhuofen:Hello everyone! Happy new year! Just after 2020, many friends feel that 2020 is a very extraordinary year; The Covid-19 epidemic has had a great impact on the whole world, a great disaster. If we look back at the history of the development of human society, we can see that in the past 2000 years, this virus and this epidemic occasionally occurred. Like the book we are reading now, there are detailed statistics on the impact of plague on human society. You can see that in the past 2000 years, there were often various plagues and epidemics that affected the development of human society.

For example, in ancient Rome, measles and smallpox killed almost 5 million people. You can also see that this plague affected different countries in different historical stages, from Europe to Latin America, to China and even to the whole world. The virus may be related to measles and smallpox, typhoid fever, plague or influenza virus.

Last year, pneumonia was mainly caused by the new coronavirus. If you look at the chart (on the right), there are quite a few people killed each time, some are millions, some are tens of millions. In the course of our human history, this plague also happens from time to time. In the process of the development of our human society, besides the plague, there are some other natural disasters, such as the well-known earthquake.

Take a look at our chart. Earthquakes also have a great influence, so in Europe, in the era of the Roman Empire, in the Middle East and even to China, and even to Peru and Southeast Asia in South America, the influence is quite severe, and the number of people killed each time ranges from tens of thousands to hundreds of thousands.

If we compare the plague with the earthquake, there is a difference. The plague does not pass in a day or two. Take the Covid-19 in front of us (for example), everyone has been affected for a very long time, almost one year has passed. What about the earthquake? It’s fierce, but it usually passes at once. Of course, its impact (very serious) and the reconstruction process will take time.

However, this kind of natural disaster, like an earthquake, has less impact time than the epidemic. Speaking of natural disasters, apart from earthquakes, we all know that floods often occur in our human society, and this one has also occurred since the ancient Roman Empire. Floods in the Yellow River and the Yangtze River in China are also frequent, as are floods in other countries, and the impact of floods is also very severe. Some floods killed tens of thousands of people, and some affected millions of people. Floods are also relatively short-lived, usually lasting a few weeks or a month. Of course, the process of reconstruction is still relatively long, but it doesn’t take longer like a plague.

We talked about these plagues, earthquakes and floods. How can our human society face these disasters? How to prevent these disasters? Let’s take a look at this plague epidemic. Generally, what we can do is to work hard to develop a vaccine, develop this vaccine, and then widely apply it. If we can widely use this vaccine, we can have an effect of preventing the spread of infection.

Looking back on vaccines against plague, we can see that smallpox was introduced in 1796, cholera was introduced in 1879, and others like typhoid, plague and measles. If you look at the time when this vaccine was developed, it actually appeared in the past about 200 years. This is the development of times medicine or modern medicine.

After we had these vaccines, they were widely used, and the threats of smallpox, cholera, diphtheria, typhoid fever and plague gradually decreased. It is not completely zero, but it can be controlled. Today, we are not too worried about the impact of smallpox on the whole human society, because we have a good vaccine, and so are other epidemics.

Modern medicine has made great contributions to controlling these plagues, but it has been more than two hundred years. We are now facing Covid-19, and we all know that in the past few weeks, different countries have made great efforts to develop this vaccine, and then it has been widely used in all aspects of society. They attach great importance to the development of this vaccine, mainly because of the serious impact of Covid-19 on the whole social economy. If this vaccine is not widely used immediately, it will be even worse for the economic situation of these countries.

Everyone knows that it was Britain that first used vaccines and applied vaccines. This vaccine was first used in Britain, and it has been used for almost several weeks now. The National Health Service says that more than one million people are vaccinated every week, so are other countries. We see that it is widely used in Russia, the United States, the Middle East and Latin America, and even the vice president and president-elect of the United States have been vaccinated.

Experts in the medical field expect that after the vaccine is used, our life will gradually return to normal. This is the opinion of our frontline experts. For example, professors from the medical school of the University of Hong Kong estimate that the epidemic situation will be gradually controlled in the second half of this year after the vaccine is widely used. We can’t return to zero immediately, but most of them can be controlled, and life will gradually become normal. Maybe in another year, the situation will be greatly improved. Of course, there may be some occasional outbreaks.

Our country has also made a lot of efforts in vaccine development. Now China’s vaccine is not only widely used in China, but also very popular in many countries around the world. There are hundreds of thousands of people, many of whom have been vaccinated, and there is no special infection. It will definitely be of great help for the future life to gradually become normal.

Looking back, what happened to Hong Kong? Director Chen (Food and Health Bureau of the SAR Government) said that he hoped that Hong Kong people would be widely vaccinated in the second half of the year, and he was also prepared to vaccinate all Hong Kong people with COVID-19 vaccine free of charge. It is estimated that the situation will gradually improve in the second half of the year, and society will gradually return to normal, so next year will be even better.

I just talked about the situation in Covid-19 and mentioned other natural disasters. How do we deal with other natural disasters? Earthquakes just mentioned, such as Wenchuan earthquake and Tangshan earthquake, have a very serious impact on human beings and the country. As a scientist, I should tell you truthfully, if you ask me, when and where will the next earthquake happen? Actually, we don’t know, really. Does that mean that I don’t know where the next earthquake will happen and how big it will be, so I’ll just sit and do nothing? That’s not true either.

We can use other methods to reduce the impact of earthquakes on our human society. How can we reduce it? This kind of work is called disaster reduction and prevention, reducing its disasters. Although we can’t accurately predict the coming earthquake, we can reinforce houses and various buildings. Reinforcement is to keep them from collapsing when the earthquake comes. Although the impact of the earthquake is still there, it will not collapse, that is to say, if we strengthen the house and improve its seismic standard, then it can reduce its disasters.

There are many houses in the earthquake zone now. Where is the earthquake zone? Japan, China, Tangshan and Northwest China, California, USA. We can use these methods to strengthen the house. Here are some concrete examples. This is some methods of earthquake-resistant building design. In fact, there are several methods. In our earthquake-resistant work, one of them allows us to design the house to be more elastic. It is more elastic. It can shake around during the earthquake, but it will not collapse. This is a method called "earthquake resistance", which means it can withstand this earthquake.

The second one is called "earthquake suppression". Earthquake control means controlling the earthquake, using steel bars and various reinforcement methods to control the amplitude of the earthquake, which is also a design scheme. Another scheme is called "earthquake-free". What does it mean? It’s the foundation, the foundation, which collects the seismic energy of earthquake waves. It’s a bit like driving. The car has a vibration control device. We also put this device on the building foundation, which can also reduce the vibration amplitude. That is, I can’t accurately predict when the earthquake will happen, but I can minimize the impact of the earthquake and prevent it from causing a major disaster.

Everyone knows that there are not many earthquakes in Hong Kong. Hong Kong is not an earthquake zone. Although there are no earthquakes, there are landslides. Landslides are called "landslides" in Hong Kong and "landslides" in the Mainland. Landslide and debris flow all refer to the same thing, that is, the hillside slides down. For example, in 1972, there was a big landslide on Baoshan Road next to the University of Hong Kong. When the landslide slipped down, it washed down a building with it and bumped into a part of the building below. Think about it, the impact of this disaster is still quite great. At that time, 67 people were killed, (known as the "618 disaster"). On the same day, in addition to the landslide on Baoshan Road, there was also a landslide in Xiumaoping, Kowloon. At that time, there was heavy rain, and 71 people were killed in Xiumaoping landslide. Together, almost 140 people were killed. This kind of disaster also happened frequently in Hong Kong that year.

In the mid-1990s, there was a team in the University of Hong Kong, and I was in charge of this work. We developed a method to reinforce and stabilize the hillside, which was called soil nailing. Soil nailing is called "soil nai" in English. At that time, we had several doctoral students engaged in various research work, some of them were indoor research, and some were doing various field experiments in the wild. We have done a lot of experiments on the slope of a road in Ma ‘anshan, and also some experiments on field soil nailing to strengthen the slope in Kadoorie Farm near the rural areas of the New Territories, to ensure that this soil nailing reinforcement method is effective and usable. After we have done a good job in this field, the method of soil nailing reinforcement has been widely used.

How to do it? First, drill a hole in the hillside, put a steel bar in it, then drill a hole to fill the surrounding space with cement, and then put a nail head on each soil nail. After the soil nail reinforcement, I tied the whole hillside together. The soil and rocks on this hillside are bound together, which plays a reinforcing role, and this hillside will not slide down. After it is reinforced, it will not slide down when it is tied together. I can also plant grass and trees outside the slope. I have a safe slope, which is safe after reinforcement. At the same time, my planting grass and trees also has an environmental protection effect. When you look outside, you can only see my grass and my trees, but you can’t see my soil nails, which means safe and environmentally friendly. This is also a creation of Hong Kong.

This method of soil nailing has been widely used in Hong Kong for more than 20 years. Driving soil nails into all slopes, this is the method of soil nailing reinforcement, and this is the whole set of tools. In the past twenty years or so, tens of thousands of slopes in Hong Kong have been reinforced by this method. After reinforcement, it looks like this. You see the grass, you see the tree, you can’t see my soil nails, because the soil nails are hit inside and you can’t see them. Before using this method, we temporarily put some cement slurry on the slope to separate the rainwater, but this method looks very environmentally unfriendly. In the 1980s, many people wrote to newspapers saying that this method was not environmentally friendly. Later, we adopted the method of soil nailing and greening, and it became like that (on the right).

At present, tens of thousands of slopes in Hong Kong are planted with soil nails (reinforced), which is done everywhere. This has been done for more than 20 years, and this method has been adopted everywhere. I think if you recall, in the early years, landslides often caused casualties in Hong Kong. In the past ten years or so, you have rarely heard this kind of thing, that is, you have never heard of how many people were killed in landslides. This story has been rarely heard, basically not. Over the past decade or so, there have been basically no casualties caused by landslides and landslides. Even this method is quite useful. This method was first developed in Hong Kong. Now in China, in other countries like Britain and Canada, this method of soil nailing is used everywhere, and then planting grass and trees is an environmentally friendly method. That is to say, the landslide disaster in Hong Kong in the past, now we can basically control and solve this problem through this soil nail reinforcement and this safe and environmentally friendly method.

Another natural disaster that everyone is familiar with is flood. China used to have frequent floods, and it is a big country with many floods in the Yellow River and the Yangtze River. If we look back, why are there frequent floods in China? In fact, there are two main reasons, one is that heavy rain has caused disasters, and the other is heavy rain. In July and August of the summer of 2020, there were several weeks of heavy rain in the southern part of China, which was a disaster caused by heavy rain.

Another important reason is that we have needed a lot of wood for building houses for thousands of years. People need wood to build a house, and the emperor also needs a lot of wood to build a house. Qin Shihuang built "Epang Palace". How do you write Du Mu’s poems? "A Fang goes out, Shu Shan is bald" is bare "bald". That is, if you build a "Epang Palace" of Qin Shihuang and cut down all the mountains (trees on it) in Sichuan, then the hillside will become bare without planting any more. It’s bare and the vegetation is gone. If it rains a little, it will wash all the sediment on the hillside into the river below. After rushing into the river, the water generally flows at a higher speed in the upper reaches of the river, that is, it flows very fast, and the sediment will not settle.

In the middle and lower reaches, the Yangtze River reaches the Jianghan Plain in Hubei, the Jianghuai Plain in East China, and the Yellow River reaches the North China Plain. In the plain area, the velocity of water is relatively low, and the sediment will settle down when it flows slowly. When the sediment settled, it silted up the channels of the Yellow River and the Yangtze River, and the sediment piled up on the riverbed, slowly raising the riverbed, and after raising it, it was higher than the surrounding area.

Let’s take a look at it later. It is more than ten meters higher than the Yellow River in some places around, and the Yangtze River may be about 5 to 7 meters higher than the surrounding area. Because of this, there are often floods. Because the riverbed is high, when the rainstorm (coming), the water level of the river overflows the riverbank, and there is another big flood around it, which may be affected every time. There may be tens of thousands to hundreds of thousands of people killed. How can we face the threat of such floods?

We can’t avoid the rainstorm, even if it rains, you can’t help it. It will still rain, but we can use water conservancy projects to control and regulate the flow of rivers, which can be done. For example, in July and August last year, the whole southern region, especially Sichuan, had almost a year’s rainfall in two or three days. Not only did evening rain rise in the autumn pool, but all the rivers in Sichuan experienced a severe water rise. However, we can adjust the water levels in the upper reaches of the Yangtze River and the rivers in Sichuan through the Three Gorges Dam of the water conservancy project.

Through the Three Gorges Project, we will not let the flood suddenly flood into the Jianghan Plain downstream. What’s in Jianghan Plain? There are Wuhan and Jingzhou, all on the same plain. If this flood comes down, it will be terrible, and tens of millions of people will be affected. Through these water conservancy projects and the Three Gorges Dam, we control the flow, that is, we should stop it from rushing down immediately, and then release it slowly. When you put it slowly, control the flow under the condition of control.

I used to have many friends who lived in Wuhan. In 1998, when there was a flood in Huazhong University, almost 1 million people went to protect the embankment in Wuhan. This embankment is not only for ordinary people, but even the secretary and mayor went up and the Prime Minister came down to help. Everyone has heard about these situations. Last year, although it rained heavily in Sichuan for several weeks, the water level was quite high, and there were many flood peaks, but the flood peaks were also controlled by the Three Gorges Dam water conservancy project. It was slowly released step by step, and my friend who lives in Wuhan was also by the river, but he was enjoying the cool by the river, and he didn’t do any dike protection work. Even this water conservancy project can still work, and the flood peaks can still be safely spent.

More importantly, what our country has done in the past is that since the flood in China in 1998, we have rebuilt the mountainous areas in the west of China, that is, the vegetation forest areas in the upper reaches of the Yellow River and the Yangtze River. Rebuilding vegetation can (can) reduce soil erosion, reduce river sediment and improve the ecological environment. I’ll tell you later. I just mentioned that for thousands of years, due to the need of building houses and heating in winter, we often went to the mountains to cut down trees. After cutting, we didn’t plant them again. As a result, the vegetation on the hillside disappeared, and the topsoil was exposed on the surface. When it rained, the sediment was washed into the riverbed.

What about the result of cutting down trees? Almost all the trees in the western mountainous areas have been cut down. Before you traveled to the Loess Plateau, you would see the bare Loess Plateau, just like this. Sediment rushed into the river, and the sediment concentration in the river was relatively high. The Yellow River is even worse. Why is it called the Yellow River? In fact, many rivers in China have a relatively high amount of sediment, such as Hongshui River, Qishui River and Honghe River. Why do you call it red and yellow? That’s why its sediment concentration is particularly high.

As I mentioned just now, when the sediment rushes to the river channel, it raises the riverbed. The riverbed of the Yellow River is 13 meters higher than the surrounding ground. This means that the Yellow River is in Henan and in Kaifeng. There is a famous Kaifeng Tower in Kaifeng. You can see that the riverbed is more than 10 meters higher than the surrounding area. In this case, we call it "hanging river". It means that the river hangs in the sky, hanging in the sky.

The Yangtze River is not much better. This is a situation in the middle reaches of the Yangtze River, near Jingzhou. When you see Jingzhou, it is all above it. There is a Jingzhou levee, and there is a house below. The local people say that "people walk at the bottom of the river and water flows on their heads". This is called "Jingjiang Hanging River", and Jingjiang is the name of the Yangtze River in Hubei. The Yangtze River is called Chuanjiang in Sichuan and Jingjiang in Hubei, which are actually the Yangtze River. You see this situation, where is Jingzhou section? You see the land next to it, which is the middle reaches of the Yangtze River. After crossing the street, it is basically a plain area.

You can think about it, this river is above your head. If it rains heavily and the water overflows the embankment, it will definitely be another big flood. In the history of China, if you look at some records of the Ming and Qing Dynasties, there are often such big floods, and there are tens of millions of people (affected). This is a cross-sectional view of the north and south, and (the far right) is the Yangtze River. The red section of this topographic map is calculated in kilometers, and the other is in meters. But you can also see that the Yangtze River is protected by a riverbank, and the riverbed of the Yangtze River is about five or six meters higher than the surrounding area.

The same is true of Hanshui River, the largest tributary of the Yangtze River in Central China, and the same is true of Dongjing River, a tributary of Hanshui River. That is to say, the big rivers and riverbeds in China are generally higher than the surrounding areas, and they are all suspended rivers, and every time it rains heavily, there is a threat of floods. It is for this reason that many water conservancy projects have been built since the founding of the People’s Republic of China. Like the Three Gorges Project on the Yangtze River and the Xiaolangdi Project on the Yellow River, they can basically control and regulate the flow. When the flood peak comes, it controls the flow well to prevent the flood from leaking to the downstream great plains at once.

After the flood in China in 1998, it was Premier Zhu Rongji’s time. He discussed with you how to solve the flood threat in China for a long time. At that time, he adopted the suggestions of several academicians of the Academy of Engineering. At that time, I also took part in some work in this field. We suggested that we should not cut down trees in the middle and upper reaches of the Yellow River and the Yangtze River in the future, and rebuild the vegetation in the central and western regions and the forest areas in the mountainous areas in the central and western regions.

After 1998, the vegetation reconstruction project was started in the middle and upper reaches of the Yellow River and the Yangtze River. The vegetation reconstruction project is literal. We generally call it the "Green Long March", which is to rebuild trees in our mountainous areas from generation to generation. In the western mountainous areas, including the Loess Plateau and Inner Mongolia Plateau, many deserts and deserts have replanted trees for more than 20 years. If you go to the Loess Plateau today, you will see trees planted in many places, which is different from before.

After planting trees, the problem of soil erosion will be gradually reduced. There are trees on the hillside to hold all the sediment, so that the sediment will not flow to the river bed, thus reducing soil erosion. The sediment transport capacity of the Yellow River and the sediment concentration in the Yellow River water have greatly decreased in the past twenty or thirty years, mainly because trees have been planted, and soil erosion has been reduced after trees have been planted.

If you travel to the Yellow River today, if we can go back today, you can go to Hukou Waterfall. The water in the Yellow River is much clearer. The same is true of the Yangtze River, where the sediment concentration has dropped significantly. This was observed at a hydrological station in the middle and lower reaches of the Yangtze River, and the annual sediment discharge has obviously decreased significantly.

I just said that in the past few decades, trees have been planted everywhere in the "Green Long March", including in desert areas and the Loess Plateau. If you look at the national forest coverage rate, it has tripled from 8% in the founding of the People’s Republic to about 23% today. This is a very big growth. After planting trees, the whole ecological environment has gradually improved. According to the statistics of the United Nations, the annual increment of forest area in China ranks first in the world, while other countries combined can’t keep up with the increase of forest coverage in China. This work is very remarkable. Of course, it is the result of continuous efforts of generations, and its impact on the whole ecological environment is very clear.

Just now, we talked about plagues, earthquakes, landslides and floods. These are called natural disasters, and such natural disasters continue to occur. We live on the earth, and the earth is our home to settle down. The nature around us is beautiful, but it also has an impermanent story, whether it is nature or the earth. If we look back at history, after every disaster and plague, we human beings are born through robbery. After learning from one thing, looking back at the development process of human society, we have developed on the basis of constantly overcoming difficulties and disasters.

In the face of disasters and epidemics, we need to do a lot of disaster reduction and prevention work and anti-epidemic work. This mainly depends on scientific control of this plague, mainly on modern medicine. We are in this "epidemic" environment, like for a long time in the past. As human beings, we inevitably feel anxious. Therefore, in addition to doing a good job in epidemic prevention, disaster reduction and prevention, there is also a very important need for peace of mind. How to make us face these disasters more calmly is the need for peace of mind.

But how can we reassure everyone in a disaster and an epidemic? I suggest here that we can borrow some religious philosophy and humanistic care from our eastern civilization. For example, we can refer to it. Before the disaster last year, you may remember that there was an Asian financial turmoil about 20 years ago. The Asian financial turmoil also had a great impact on Hong Kong at that time. Let’s take this as an example. If you look at this kind of news in Hong Kong newspapers in those days, what kind of big stock market crash broke out, causing many shops to stop operating, and many people became negative assets. What is "negative assets"? That is, I borrowed money and went to the bank for a loan to buy a house. The house I bought may be 10 million yuan, and the bank may lend me 7 million yuan. When the Asian financial turmoil comes, the price of that house may drop to 5 million yuan, so the money I sold the house is not enough for the bank to repay the loan of 7 million yuan, which is what I mean. Many people commit suicide because they can’t stand it.

You may remember that in the face of this adversity at that time, we had an old gentleman, a master of Chinese studies in Tsung i Jao in his 90s. Rao Lao knew that many people in Hong Kong were very unhappy at that time, and he used his methods to reassure everyone and send them a blessing. He is a great scholar and a great calligrapher. He is the president of Hangzhou Xiling Printing Society. He wrote 260 words of Heart Sutra in calligraphy. You can see that every word of Prajna Paramita Heart Sutra is quite big. At that time, after he finished writing, he hung it on the wall, and every word was written in such a big size. He asked us to help him carve this 260-word Heart Sutra on 38 pieces of wood and put it in the Heart Sutra Simple Forest in Ngong Ping, Lantau Island. Now when we go to Ngong Ping, we will see the "Heart Sutra Simple Forest", and this is how the "Heart Sutra Simple Forest" came about.

Rao Lao also went to see the Heart Sutra when it was built. Why did he write this calligraphy of Heart Sutra? Rao Lao feels that you want to make people feel at ease. You can’t just say a few words and people will feel at ease. The best thing is for us to reflect on it and study it. A Buddhist sutra full of wisdom like Heart Sutra, from which you can set your mind at ease, was Rao Lao’s idea at that time.

Why do you say that? What is the magic weapon of the Heart Sutra? I’ll give you a supplementary explanation here. The Heart Sutra is actually not long at all. It is divided into two sections. The first paragraph is actually just a few words, very short. In the first paragraph, it is said that "when you look at the Bodhisattva, you can walk deeply like Paramita for a long time, and when you see that the five aggregates are empty, you will suffer all kinds of hardships". It is written in classical Chinese, which seems not easy to understand. If we use modern words, it’s probably like this. In the vernacular, it means "observing the Buddha". Who is the Buddha? Viewing from the Bodhisattva means representing the "Guanyin Bodhisattva" next to it. Why is he called Guanyin Bodhisattva and Guanyin Bodhisattva?

In fact, it is very simple. Buddhist bodhisattvas practice both compassion and wisdom. In Buddhist language, this is called "double luck of compassion and wisdom". Both compassion and wisdom are practiced at the same time and are used in our lives. Bodhisattva If he practices compassion, like Guanyin Bodhisattva, he practices compassion to help the poor, and he will help you solve your immediate difficulties whenever you need it. That is, when you hear that you need him, he will come to help you. This is (yes) hearing about it. So when he practices compassion, we call him avalokitesvara. It is when he hears the sound of salvation and shows compassion that we call him Guanyin Bodhisattva.

In addition to practicing compassion, he also practices intelligence. How to cultivate wisdom? He practices wisdom in deep meditation, that is, through deep meditation, he can observe everything in the world, and everything has its reasons, causes and causes. Is that everything will not happen for no reason, there are his reasons behind it, and it will not happen for no reason. He saw this truth, he realized this truth, he realized this truth. Realizing this truth, he can clearly find out the causes behind everything, and he can understand the reasons behind everything, and there is also a process of karma birth and death. That is, if this reason exists, it will happen; If this reason did not exist, it would not have happened.

Let me give you an example. Don’t say something as serious as this epidemic. It’s winter now, and it will be Spring Festival in two months. Spring, what’s wrong with spring? Spring is blooming! You see a tree with flowers growing. Why do flowers grow? It is spring that comes. There is sunshine, rain and dew, sun and soil, and these conditions are all met. In spring, the temperature is warmer and there is rain. Under this condition, the tree in front of us will grow flowers, maybe a peach blossom. We like peach blossoms during the Chinese New Year, and when we see them, we come out at that time.

Why doesn’t it come out in the middle of winter and December? It is the twelfth month of winter that does not have the conditions for it to bloom. After two months, spring has come, and spring blossoms are the conditions for flowering. Everything, including the flowering of a tree, has its conditions. With conditions, it will blossom, but without conditions, it will not. Of course, I can build a greenhouse, and that’s another way. Is a simple thing, like flowering, it needs flowering conditions, flowering conditions are sunshine, rain and dew will bloom, after this condition is gone.

So what does it mean to say "karma is born and died"? That is, if conditions permit, it will blossom; if conditions do not permit, it will not blossom, as simple as that. The epidemic is the same! A condition makes the epidemic appear, and it will be there. Earthquakes and natural disasters are the same! Natural disasters also have their reasons. If conditions change, it may not happen again. Then you understand that everything has its reasons and karma behind it, so you may face it more calmly.

For example, if I am a student and my exam results are not good, then I must be very upset. No (good) may also have a reason. Why didn’t I do well in the exam? Didn’t get into my favorite university? One of the reasons is that I may not study hard, or I can’t study properly, that is, I can’t read my book effectively (efficiently). You don’t study well and you don’t study hard, which is one of the reasons why you can’t get into the university and your favorite university.

You’ll understand when you find out the reason, and it doesn’t mean you just sit there all the time. Think about it, I didn’t study hard, so I should study hard next time. I study hard, I improve this condition, I improve this karma condition, then I study harder next time, and I can be admitted to my favorite university. That is to say, you understand the reasons behind everything. If you improve this condition, you can do better. This is the reason.

If we understand every situation, every epidemic situation and epidemic situation, we understand the reasons behind it, find out its reasons and find out the solutions, we can face it more calmly, and you will be more calm in your heart, so you will not be too upset and you will be able to tide over the difficulties. The meaning of "going through all the hardships" is to get through this difficulty. To get through this difficulty, you don’t just sit there, you just (want to) find out the problem and try to solve it. Solve it, and you will be able to tide over the difficulties. This is a short first paragraph of the Heart Sutra, which may only be more than 20 or 30 words. We call it "karma view", the most important truth of Buddhism, and write this "karma view".

If you look back at these words, it’s only 25 words. These 25 words are included, telling you that there are reasons and conditions behind every suffering. If you change this condition, you can solve the problem and you can "get through all the hardships". That’s what it means.

I just said that this is the "karma view" of Buddhism. According to legend, it is one of the two truths that Sakyamuni realized under the bodhi tree that year. The first one is called "karma view", which is the truth I just talked about in the first paragraph of Heart Sutra. Second, another important truth that the Buddha realized under the bodhi tree in those days was called "four truths view". Let me introduce the "four truths" here. In Buddhist language, the "four truths" are suffering, gathering, extinction and Taoism. If we use our modern language, what is "suffering"? Suffering means that there is a problem, and trouble comes, which makes you feel very painful and unhappy. This is "suffering".

What does "set" mean? It is suggested that instead of complaining, you should try to find out the root of the problem and think calmly. Why did this problem appear? Find out the root of the problem. For example, I didn’t do well in the exam and didn’t go to college, which made me very painful and annoyed. This is "bitter". "Set", find out the root of the problem, the root of the problem is that I didn’t study hard, and my method of studying is not right. These are all, and this is the root of the problem. Find out this "set".

It is not enough to find out the "set", but the third step is to "destroy". "Extinction" means finding a solution to the problem. I know that my grades are not good, and the main reason is that I don’t study hard. I always play computer games and don’t study well. This is the problem. After finding out the root cause, I know that if I want to get better grades, I can only work harder. Then the way to find out this problem is to study harder and study my book well. This is "extinction", which means reducing this problem.

The meaning of "Tao" is to carry out this (method), stick to it, and implement the solution to the problem. I will study hard in the future, but I don’t have the final say. I have to implement it seriously. I have to stick to it to get good grades. Bitterness, concentration, extinction and Tao are actually the "four steps" to solve the problem; Is to find out the problem first, find out its reason, find out the solution, and conscientiously implement the solution, that is, suffering, concentration, extinction and Taoism.

No matter what problems you encounter in your life, you can use this "four-step" method to solve them. If we are doing scientific work, this is also a basic step of scientific methodology, which is applied to those natural disasters and major earthquakes I just mentioned. The Wenchuan earthquake brought great pain, and about 90,000 people were killed. This is a great pain. How to solve it with the "four truths" of "suffering, gathering, extinction and Taoism"?

Earthquake is "bitter", I find out its root. The root cause is that the Longmenshan fault in central Sichuan, that is, the fault on the southeast edge of the Qinghai-Tibet Plateau, is often dislocated and displaced, and the displacement has caused the earthquake. Just now, we don’t know when there will be another earthquake, but we can improve our seismic standards and do a good job in building reinforcement projects, which can reduce its damage and disaster; This is a process of suffering, gathering, extinction and Tao.

Earthquake is like this, tsunami is like this, you find out the reason and try to solve it. The same is true of floods. I just reported to you that the root cause of floods is that we cut down trees, rain heavily, and soil erosion. Then we should rebuild vegetation and improve our ecological environment now. This is the method of prevention and control, and it is also the method of extermination and Taoism. It is that every disaster and every problem can find some solutions.

Many years ago, we had a SARS, and we also used an epidemic prevention method, that is, we found the cause of this SARS, that is, there was a non-coronavirus or something. Now it’s the same in COVID-19. You find the root cause and try to find a solution, which is to develop vaccines. Find out the root of every problem, find out its solution, and try to implement this method. That’s it.

If people want to feel at ease, the first thing is that you should be wise first. This is what the first paragraph of Heart Sutra says. You must "see that the five aggregates are empty" before you can "overcome all the hardships". The meaning of "seeing the five aggregates is empty" means that you should find out the root of the problem and understand what is behind everything. If you can be so wise, you can feel at ease, and you can live in the present and live in the present.

Buddhism often talks about the phrase "live in the present". What does it actually mean? That is, if you can feel at ease, you can concentrate on what you need to do right now. For example, I am a teacher. I am a teacher. I concentrate on doing a good job as a teacher and teaching my books well. If I live in the COVID-19 epidemic, as I have lived in the past almost a year, I will concentrate on the epidemic prevention work, do my part, wear my mask, and I will do the isolation work. These tasks need to be done. This means "living in the present".

If I’m unlucky and I’m sick, I still have to concentrate on doing the patient’s job, cooperating with the medical staff’s treatment plan, etc., that is, you need to do a good job in every post and every moment, so you just have to concentrate on doing it well. If we can concentrate on the work at hand, then we won’t be distracted, and we won’t be paranoid. If we can’t be distracted, naturally we will have no worries.

Therefore, in fact, the so-called "living in the present" is the same thing as "having a free mind", that is, two sides of the same coin. If you can "live in the present", you can "have no worries", that’s what it means. Finish one thing, just like pressing "clear" on your computer. Clear it, and don’t dwell on it. What has been done is over, let him go, and then you can concentrate on the next job. If you can do this, even though you have endless things to do every day, you can be busy. When everything is done, just put it down. That’s what it means.

Repeating this "view of karma" teaches us that everything in the world has its reasons, whether it is prosperity or adversity. Even when the scenery is very beautiful, we won a lot of honors. Of course, there are reasons. When we encounter difficulties, there are also reasons. Difficulties also have a process of birth and death. With conditions, it will appear, and without conditions, it will not. There are conditions, but there will be no conditions, which will change.

The so-called change is impermanence, and impermanence seems a little worrying, but if you think about it seriously, it is precisely because of impermanence that you have a chance to improve. That is, I am in the middle of the epidemic, and now I am in a very difficult epidemic situation in COVID-19. Because of the development of the vaccine, I have a chance to improve, and it will not remain unchanged forever.

In the face of adversity, the method we adopt is to face it, accept it, deal with it well, and put it down after doing it well. This is also the same reason as the "four-part" of suffering, concentration, extinction and Tao I just mentioned, and put it down after finishing it. There is a short story. When Ma Yun was running, a fan told him, "You have gone through many difficult days to achieve this achievement today. If I were you, I would have been crazy after so many difficulties! " Ma Yun said: "Hard days are not sad, because you understand that hard days are impermanent, and it will change. You can actively improve the environment and make it a good day!"

Don’t be too pessimistic in suffering, but try to improve it. This kind of suffering is part of our growth. Finally, I will share a little story with you. This short story is that in a farm in the western part of the United States, there is a farmer who grows wheat, and in the United States, he grows wheat. Besides being a farmer, he is also a very devout believer. He prays to his God every night, which means praying every day. As a farmer, what do you think his prayer is asking for? Of course, it is to seek good weather and a bumper harvest in the coming year. This is what most farmers will say, and he also talks about it.

His god feels that I am still a very devout believer, so I will promise you that you will have a good weather next year, and there will be no wind injuries or pests, so that you can get a bumper harvest. The farmer was so happy that he planted the wheat seeds. I planted it in spring and saw it grow well in summer. When I harvested it in autumn, I knocked down this wheat valley and waited happily for a bumper harvest. After opening the wheat valley, he saw that the inside of the wheat was empty, and many of them were not in the millet.

What’s going on? You think that as a farmer expecting a bumper harvest, you are certainly unhappy when you encounter this situation again. Just pray with his god again, I hope god will show him. When God saw it, he understood, and said to him, "You should know that the wheat you planted is a plant, and the growth process of the plant is a natural process. This natural process includes the days when the sun shines and the days when the wind hurts the insects. The wind hurts the insects is actually a part of its growth process. Without it, its growth process is incomplete. The growth process is incomplete, and the growth of wheat is also incomplete, so you can’t grow millet. "

Of course, this story is fictional, but we must understand that in the process of wheat growth, wind injury and insect pests are part of it. The same is true in our life. We encounter all kinds of challenges and difficulties, which makes us stronger and more able to face these difficulties and hardships. It makes us more capable of facing greater challenges and may be more successful in the future. So we say that suffering is one of the growth genes of human society. Because of this hardship, we will become more capable and stronger in the process of overcoming difficulties, and there will be more successful conditions in the future.

Finally, I want to say that this epidemic reflects that there is not an ideal and harmonious relationship between us and nature. Looking ahead, we should pay more attention to the harmonious coexistence between man and nature. The Chairman of the Supreme Leader said not long ago, he said: "Humans can no longer follow the old road of only taking, not investing, only developing, not protecting, only using and not repairing." That is, you can’t always bully nature, you can’t always take the benefits of nature, you should give back to nature.

Many years ago, I listened to Mr. Tsung i Jao, who also talked about a concept called "mutual benefit between man and nature", that is, everyone takes good care of each other, that is, nature gives you many benefits, and you should also give back to nature and do something good for nature. In English, this is called "mutually beneficial". Everyone should help each other. If we can do this, slowly, this disharmony between man and nature will gradually reduce these problems. My report for today ends here. Thank you very much for your patience, thank you, thank you!

In 2024, Shaanxi will focus on promoting the development of digital economy from six aspects.

  With the new round of scientific and technological revolution and the accelerated evolution of industrial transformation, the rapid development of digital technologies represented by artificial intelligence, 5G communication, big data and cloud computing, quantum information, etc., has become a key force in reorganizing global factor resources, reshaping the global economic structure and changing the global competition pattern.

  The so-called digital economy refers to a new economic form with data resources as the key element, modern information network as the main carrier, digital technology integration and digital transformation of all factors as the important driving force, and digital empowerment as the prominent feature. Nowadays, data has been defined as the fifth largest factor of production after land, labor, capital and technology in China, and the level of digital industrialization also determines the recognition, growth and competitiveness of a regional digital economy.

  In Shaanxi, digital technology is deeply integrated into the whole process of economic and social development, and the digital economy in the province is on the rise. According to preliminary estimates, the total scale of digital economy in Shaanxi in 2022 exceeded 1.2 trillion yuan, up 13.9% year-on-year, ranking fifth in the country; In 2023, the scale of digital economy in Shaanxi is expected to reach 1.4 trillion yuan, accounting for over 40% of GDP. The development of digital economy has not only injected surging momentum into Shaanxi’s high-quality development, but also made positive contributions to strengthening the construction of digital Silk Road in the 21st century.

  How do numbers empower thousands of industries in Shaanxi? How important is big data to economic and social development? Recently, the reporter from China Business Daily visited the Fast Xi ‘an Gaozhi New Wisdom Factory and the Iflytek Silk Road Headquarters.

  Xi ‘an Fast Kochi New Factory

  Production efficiency increased by 72%

  Can realize 6-hour unmanned black lamp production.

  On April 11th, in the smart factory of Fast-Tech Gaoxin Company in Xi ‘an, in the 33,000-square-meter machining workshop, an unattended AGV car with a 5G logo was shuttling materials and finished products. At the work station, the flexible mechanical arm sometimes moves and sometimes stands still, which is in tacit cooperation with the CNC machine tool; On the big screen of big data analysis room and joint conference area, all kinds of real-time data are intuitive and clear.

  Chang Hengchen, the person in charge of the machining workshop, said that this workshop mainly produces gearboxes and clutch boxes for heavy vehicles. In the blank feeding area, the AGV car transports the blank here. After the robot recognizes it, it will code it to confirm its identity. All subsequent processes will identify their identities according to this code, and you will know what needs to be done in which process by scanning the code. Under the condition that the production conditions are available and there is no abnormality at the site, the production line can be unmanned for several hours, which is called "black light factory". There are only a few employees on a line, and the biggest role is to handle abnormalities, tool change, system operation, handling and other work all to robots and intelligent mechanical arms such as AGV. When the finished product comes out, the AGV trolley will send it to the conveyor belt of the logistics center, and then directly enter the warehouse through the straight ladder and corridor for assembly. Finally, all the data are automatically summarized to the Big Data Analysis Department.

  "The traditional production mode is how many varieties there are. Each variety is made in large quantities in advance, and it takes up a large warehouse and a lot of money. We are producing here in strict accordance with the production scheduling plan. What we want tomorrow will be produced today, at most two days in advance, without pressing inventory and reducing capital occupation. " Chang Hengchen said, "In the original production process, the intermediate process had to be inspected, and it had to be inspected before it was finally put into storage. Now the intermediate links have been cancelled, because we have automated inspection equipment, which can use data in real time, and immediately report to the police if there is an abnormality and solve the problem at any time. "

  So how does the assembly workshop realize digital empowerment? Engineer Yu Ming introduced: "First of all, we convert the production requirements, design requirements and process requirements into digital languages on the R&D platform and send them to the production execution system. The production link receives data. For example, there is a rocker arm on the transmission that needs to be 30 degrees, and the process document will be written at 30 degrees and sent to the equipment end. According to this, the equipment end will have an industrial guidance. First, the infrared indicator line will be turned to 30 degrees, and then in the latter station, it will be identified whether it is assembled to 30 degrees by taking photos, so that the production will be driven by numbers. "

  "It not only drives production, but also drives logistics. When the parts list was sent to the downstream system during production, the master controller also received it. The system carries out distribution according to our list, and after that, it will compare these parts information with the actual distribution information to prevent mistakes. Finally, the batch information and production process information of these parts are stored to complete traceability. Our order progress is also fully transparent, and the upstream and downstream supply chains can also be queried in our data. "

  Zhao Jianlin, general manager of Xi ‘an Fast High-Tech Zhixin Company, introduced that the factory covers three core processes: gear, shell and assembly, in which the automation rate of gear and shell lines is 100% and the automation rate of assembly lines is 71.5%.

  The factory has realized the digitalization of core business such as process planning, intelligent production, equipment management, intelligent logistics and quality traceability. Based on emerging technologies such as cloud computing, big data, Internet of Things, artificial intelligence, etc., digital services are integrated to build intelligent scenes, forming six core technologies of "digital twinning, black light production, Internet of Everything, intelligent decision-making, green manufacturing and data closed loop".

  "Compared with traditional factories, data and services are integrated here, and all business links are opened through information systems. The whole business is closed-loop with data as the carrier. We still manufacture gearboxes, but through digital transformation, we have made gearboxes better, improving quality, increasing efficiency and reducing costs. "

  "If all of them run at full capacity, our per capita output is more than five times that of traditional factories. We are now compiling more than 140 people. If traditional factories want to achieve the same scale of output, it may take seven or eight hundred people. Smart factory can improve the production efficiency of enterprises by 72%, reduce the energy consumption by 14%, reduce the delivery cycle by 20%, and realize the six-hour unmanned black lamp production. At the same time, a new model of hierarchical control of production quality has been established to realize the whole process quality traceability of the production process. "

  "At the same time, our energy consumption has also been reduced, which is about 15% lower than that of traditional factories. There are photovoltaic power generation equipment on the factory buildings in the whole park. When the weather is good, it can generate 70,000 to 80,000 kWh a day, which can basically meet the production needs during the day. Based on comprehensive calculation, the proportion of green electricity last year was about 40%. Fast Gaozhi New Wisdom Factory is also the first zero-carbon factory in Shaanxi Province. "

  "We are based on independent development as much as possible. The planning, design and implementation of the whole factory are all done by the Faster team. These core technologies are completely in our own hands. In the use of equipment, including systems, it should be localized as much as possible. We use Qinchuan machine tool, which is the first time that domestic similar projects use domestic core equipment in large quantities. Of the 28 machine tools in the gear production line of the machining workshop, 22 are made in China, and some robots in the workshop are also made in China. This reflects the synergy of the industrial chain. Fast is the chain owner of the automobile industry chain, and Qinchuan is the chain owner of Shaanxi equipment manufacturing industry. Through chain development, we can not only enhance ourselves, but more importantly, we can drive the entire industrial chain. "

  Empowering thousands of industries with cognitive model

  On April 12th, Yin Lan, the presentation manager of Iflytek Shaanxi Branch, introduced the latest development of iFLYTEK Spark Cognitive Model at the Iflytek Silk Road Headquarters of Xi ‘an High-tech Software New City. "This is the core research and development achievement based on the completely localized computing base platform, and we are committed to using such a universal large model to empower thousands of industries." How can such a big model help empower all walks of life? Yin Lan demonstrated three scenarios respectively.

  The first scene is empowerment education. An English composition test paper appeared on the big screen, and a large model was used for intelligent correction. "This involves two key core competencies: one is OCR recognition, which means whether the machine can read the contents written by students. At present, Iflytek has achieved world-leading results in Chinese and English and formula recognition; One is the ability of machine reading comprehension. To intelligently correct the composition, you must not only be able to read, but also understand and think. Iflytek has surpassed the human average in the world’s most authoritative SQuAD2.0 cognitive energy competition. " Yin Lan introduced while demonstrating, and a dozen mistakes were quickly displayed on the screen, including the incomplete collocation of some sentences.

  The second scene is to help medical care. Yin Lan introduced that, based on the cognitive ability of iFLYTEK Spark Model, in 2017, the "Intelligent Medical Assistant Robot" passed the comprehensive written test of the national qualification examination for practicing doctors for the first time, and exceeded 96.3% of human candidates. For this reason, iFLYTEK has built a set of auxiliary diagnosis and treatment system, which provides doctors with auxiliary diagnosis and treatment, medication advice and other services on the premise of not changing the work processes and habits of grassroots doctors. She simulated the grassroots doctors on the spot to enter a medical record for the patient. The system automatically checks the medical records, and soon a red pop-up window pops up, indicating the contradiction between the medical history and the time of the chief complaint, reminding you to modify it. After the revision is completed, doctors need to make a diagnosis for patients. At this time, the auxiliary diagnosis and treatment system gives a series of recommended diagnosis lists on the right, ranking them according to confidence. The prompt information also includes the recommended examination of common drugs, professional guide documents and so on. If the doctor is not sure about the final diagnosis opinion at this time, the further consultation suggestions recommended by the system can help the doctor to consult for many times. According to reports, this system has been applied in more than 400 districts and counties across the country.

  The third scenario is to use "AIUI full-duplex voice interactive system" to simulate voice booking in noisy environment. Yin Lan introduced that in this process, she only woke up once, and many interactions and interruptions in the middle were not affected. Because the system accurately identifies and locates the position of the command sound source, it can be applied in noisy scenes, which is very beneficial to improve the efficiency and effect of interaction.

  Fang Man, executive general manager of Iflytek Shaanxi Branch, introduced that in May 2018, Iflytek landed in Xi ‘an High-tech Zone, where Iflytek Silk Road Headquarters, Xi ‘an Artificial Intelligence Research Institute and Xi ‘an Industrial Acceleration Center were built. Xi’ an Institute of Artificial Intelligence mainly focuses on active noise reduction, chip and noise reduction solutions of acoustics, as well as multilingual identification and other research fields to help the development of the Belt and Road Initiative; Based on the open communication platform of artificial intelligence, Shuangchuang Base has served tens of thousands of development teams in Shaanxi, continuously conducted incubation and industrial empowerment, and served many industry tracks and application scenarios such as education, medical care and smart cities in Shaanxi.

  In the field of smart cities, the focus is on urban brains and government services. A number of benchmarks have been set up in Xi ‘an, Tongchuan and Yan ‘an to help industrial development, urban operation and public services through artificial intelligence.

  In the field of education, actively participate in the digitalization of education and the construction of smart campus in Shaanxi Province, and serve 1.1 million teachers and students in thousands of schools in ten cities in Shaanxi Province.

  In terms of industrial empowerment and international cooperation, as of February 29th, 2024, Iflytek Intelligent Voice Open Innovation Platform has opened 650 AI products and capabilities to the outside world, gathering 6.115 million development teams, not only local in Shaanxi, but also various developers around the world. The platform has developed nearly 2.254 million applications, and the number of terminals covered by applications is about 4 billion.

  Scientific and technological innovation supports and leads.

  Digital empowerment scenarios will be more in the future.

  In Shaanxi, similar digital empowerment scenes are far more than these, such as-

  In Xi’ an Future Artificial Intelligence Computing Center, it can calculate 3 billion times a second, which is equivalent to 1.5 million high-performance computers operating at the same time. It can process billions of images, tens of millions of people’s DNA, and autopilot data for about 10 years in 24 hours.

  In Yulin, a national energy and chemical base, a roadheader with a depth of 500 meters can be "awakened" with one key, and Kekegai Coal Mine has created a Guinness World Record with a monthly footage of 812.6 meters;

  In Yangling, a new agricultural city, you can view the growth of greenhouse vegetables in real time by tapping the screen of your mobile phone, and you can plan and manage the cooperative land by using positioning software …

  While digital empowerment accelerates the cultivation of new quality productivity, the scientific and technological innovation that supports the powerful engine leading the development of digital economy-the "three reforms" focusing on the construction of Qin Chuangyuan and the transformation of scientific and technological achievements on the land of Sanqin is releasing enormous energy, which will surely give birth to the lasting bloom of Shaanxi’s digital economy after its accumulation.

  In 2024, Shaanxi will focus on six aspects.

  Focus on promoting the development of digital economy

  Huashang Daily reporter learned from the relevant departments of the provincial government that in order to further strengthen the digital economy, in 2024, our province will pay close attention to the implementation of policy measures and key tasks, and strive to promote six key tasks:

  The first is to accelerate the expansion of digital infrastructure. Promote the construction of a new digital infrastructure system in accordance with the construction concept of being moderately advanced, efficient and practical, and adapting to local conditions. We will build an intelligent and comprehensive digital information infrastructure with high-speed ubiquity, integration of heaven and earth, integration of cloud and network, intelligence and agility, green and low-carbon, security and controllability, and constantly lay a solid foundation for the development of the digital economy.

  The second is to pay close attention to independent innovation of digital technology. Focus on serving the country’s high-level science and technology to stand on its own feet, actively cultivate the strategic scientific and technological strength of the digital economy, take the national strategic demand as the guide, integrate application innovation as the traction, and seize the new frontier technology as the goal, and organize the implementation of the digital economy scientific and technological innovation project.

  The third is to expand the wide-area space of digital and real integration. Give full play to the role of digital technology in empowerment, intelligence and assignment, focus on intelligent manufacturing, smart energy and digital tourism, strengthen the application of digital technology, do a good job in the construction of industry platforms and demonstration projects, and digitally consolidate and develop advantageous industries and transform and upgrade traditional industries.

  The fourth is to accelerate the development of digital industrial clusters. Consolidate the development of hundreds of billions of core industrial clusters with scale advantages such as integrated circuits, solar photovoltaic, software and information services, and Internet of Things, build domestic leading emerging industrial clusters such as photonics, new displays, artificial intelligence, and satellites at a high level, and proactively lay out future industries such as third-generation semiconductors, humanoid robots, and smart wearable devices.

  The fifth is to improve the quality and efficiency of digital governance. Promote the scientific and efficient social governance and the convenience and equalization of public services by digitalization. Accelerate innovation and application in six areas: economic regulation, market supervision, public services, social governance, ecological protection and government operation. Take the integrated reform of "one thing at a time" as the traction, and accelerate the reengineering of government core business processes.

  Sixth, plastic support security system. Give play to the overall coordination role of the digital economy development joint conference system, implement the spiritual task list of the digital economy development conference of the whole province and the policies and measures for the high-quality development of the digital economy, establish a ledger for promoting key issues, clarify the task list, strengthen supervision and assessment, and ensure the strong and orderly progress of the work.

  A brighter future for Shaanxi’s digital economy will be more stable and far-reaching under the "two-wheel drive" of scientific and technological innovation and institutional innovation. Huashang Daily gale journalist Ma Hu zhen wen/map

Review of Early the Central Committee of the Communist Party of China Government Newspapers and Periodicals

  After the founding of the Communist Party of China (CPC), the Central Committee of the Communist Party of China stayed in Shanghai for a long time from the summer of 1921 to the beginning of 1933 (he briefly moved to Beijing, Guangzhou and Wuhan). Therefore, most of the early the Central Committee of the Communist Party of China government newspapers and periodicals were founded on the Huangpu River, which vividly demonstrated the characteristics of Shanghai culture, such as being good at innovation, leading the trend and pursuing Excellence.

  The wizard:

  "A beacon of dark China society"

  In July 1922, the Second National Congress of the Communist Party of China held in Shanghai discussed the issue of party newspapers. In August, the Central Committee of the Communist Party of China decided to establish an authoritative publication at the West Lake Conference to widely publicize the Party’s anti-imperialist and anti-feudal democratic revolutionary program.

  On September 13th, the first public publication "Guide" issued by the Central Committee of the Communist Party of China authorities came out in Shanghai. It is a weekly magazine with a format of 16, and its general distribution office is located at No.3, Lanfali, Zhaobang Road, Laoximen, Shanghai (now Lane 1047, Fuxing East Road) (the original building is no longer in existence). The inaugural issue of this newspaper’s Manifesto pointed out: "The civil strife of warlords is certainly the biggest obstacle to peaceful reunification and freedom in China, and the foreign invasion of international imperialism is a demon that restricts the free development of our Chinese nation politically and economically." "According to the real public opinion and political and economic facts of the whole country, my colleagues in this newspaper would like to call for unity, peace, freedom and independence before the people."

  Cai Hesen has been the editor-in-chief of Guide for nearly three years, and has overcome financial difficulties and insisted on publishing it with tenacious spirit. At first, the magazine was arranged according to the content of the manuscript. In order to enhance the pertinence and highlight the key points, he successively opened up columns such as "current affairs review", "inch iron", "local newsletter", "what to say" and so on. At the same time, he also wrote a large number of political essays and commentaries (more than 130 of them were signed "He Sen"). No matter whether it is a long article of five or six thousand words or a short draft of hundreds of words, he can grasp the important issues or typical cases in reality for specific analysis.

  Cai Hesen often goes to the factory to listen to your suggestions and criticisms with an open mind; In order to reflect the demands and voices of readers in time, he specially added the column "Voice of Readers" in the Guide. The magazine actively publicizes the party’s principles and policies to the public and strives to make them deeply rooted in the hearts of the people; The enthusiastic support of the public for the magazine has become the strong backing for it to persist in publishing in the predicament. The magazine is known as "a bright light in the dark society of China", and its circulation has gradually increased from more than 3,000 at first to tens of thousands. At that time, Li Lisan once commented: "The merit of The Guide is exactly the great merit that Comrade He Sen showed in the China Revolution."

  Due to the sinister environment, after the first five issues of Guide were published in Shanghai, the editorial department had to travel to Beijing, Guangzhou, Shanghai, Wuhan and other places, and its distribution scope was also expanded to many large and medium-sized cities, and it was also sold in Paris and Berlin. In October 1925, Cai Hesen went to Moscow to attend the sixth enlarged meeting of the Executive Committee of the Comintern, and immediately served as the representative of the Communist Party of China to the Comintern. The Guide was edited by Peng Shuzhi, and Zheng Chaolin undertook the specific editorial affairs. In the spring of 1927, the editorial department moved from Shanghai to Wuhan. The Guide was edited by Qu Qiubai and edited by Yang Mu Zhi. Some old comrades recalled that the maximum circulation reached 100,000 copies. After the "July 15" counter-revolutionary coup, the publication was suspended and 201 issues were published.

  The Guide took a clear-cut stand against imperialist powers, feudal warlords and supported the workers’ and peasants’ movements. It experienced the whole process of the first cooperation between the Kuomintang and the Communist Party and witnessed the development of the Party in this historical period.

  Hot Blood Daily:

  "Ten issues were published, and the sales reached 30,000."

  After the May 30th tragedy, the Central Committee of the Communist Party of China decided to publish a daily newspaper in Shanghai in order to expose imperialist atrocities in time and inspire people’s morale. Qu Qiubai led the relevant comrades through intense and busy work, and completed the preparations in just a few days.

  On June 4, 1925, Hot Blood Daily was founded in Shanghai, with Qu Qiubai as the editor-in-chief, and Shen Zemin, He Gongchao and Zheng Chaolin participated in the editing work. Qu Qiubai declared in his preface: "Now the blood of all Shanghai residents has been boiled to the climax by the bullets of outsiders … Now the strong in the world possess cold iron, while we weak only have hot blood, but we really have hot blood in our hearts, so we don’t worry that there will be no cold iron in our hands in the future. Once hot blood gets cold iron, it will be the last luck of the strong."

  "Hot Blood Daily" is a four-page edition with about 12,000 words in each issue. The newspaper is more political and encouraging: the first and second editions of the "local news", "domestic news" and "urgent news" columns mostly publish news that newspapers avoid or ignore; The third edition of the "International Highlights" column specifically reports the news of sympathy and support of the working class in the Soviet Union and other countries to the people of China; The fourth edition of the "Voice" supplement mainly publishes short comments, essays and literary works, among which there are both criticisms of wrong remarks and satires on shameful acts.

  Most of the editorials published in Hot Blood Daily are written by Qu Qiubai, such as Federation of Business Studies and Shanghai Citizens, What does the Shanghai General Chamber of Commerce want? "Who is the enemy and who is the friend? "The May 30th Massacre and the Abolition of Unequal Treaties" and so on are all highly targeted and thoroughly reasoned.

  During the editing of Hot Blood Daily, Qu Qiubai was "wanted" by the Shanghai Concession authorities, but he put his life and death aside and devoted himself to running the newspaper. Yang Zhihua, his wife, said in Memories of Autumn White: The site of Hot Blood Daily is a guest room, with a long table of white wood in the middle and several long benches around it. At that time, the weather was very hot. During the day, Qu Qiubai worked hard in his stuffy room to write articles, edit news, proofread and compose editions, and was so busy that he was sweating like a pig. In the evening, he has to listen to reporters’ reports and organize writing. Whenever a major problem is found, Qu Qiubai always goes to the workers and personally verifies the materials before publishing them in newspapers. At that time, although the work was very hard, he said to his wife Yang Zhihua, "It is much more effective to work like this than to give lectures at the university platform."

  On one occasion, when Qu Qiubai went out on business, he saw a worker reading the Business Daily and talked with him. The other party complained, "There is no newspaper suitable for workers to read, and now the newspaper can’t understand it." Inspired by this, he tried to make the writing simple and easy, and paid attention to the use of spoken language or dialect; The point of view of the article is straight to the point, and the length can be short or short, so that workers have time to read and understand. In addition, he also published many folk tunes and rap, which were popular and vivid, loved by the masses and quickly sung by everyone.

  Hot Blood Daily, the first daily newspaper founded by the Party, had a great influence in the May 30th Movement. The newspaper once revealed in the notice: "Ten issues were published, and the number of sales reached 30,000. There were hundreds of people who contributed letters and came to contact each other." Starting from the second issue, the newspaper marked the address as "Turn 567, Huaxing Square, North Zhejiang Road" next to the header; From the 12th issue, it is marked as "No.56 Huaxing Road, North Zhejiang Road, Shanghai", which is now Zhejiang North Road, and Lane 64 Huaxing Road is behind Huaxing Square.

  Due to the strangle of imperialism and warlords, Hot Blood Daily was forced to close after its 24th issue was published on June 27th, but its revolutionary propaganda has had a great influence.

  Boolean Sevik:

  "The Pointer of the New Road of China Revolution"

  At the August 7th meeting in 1927, the temporary CPC the Political Bureau of the Central Committee headed by Qu Qiubai was elected. Soon, the Central Committee of the Communist Party of China moved back to Shanghai from Wuhan, because the Guide had been forced to close, so he began to plan to publish a new the Central Committee of the Communist Party of China organ publication in secret.

  On October 22nd, the CPC held a meeting in The Politburo Standing Committee (PSC), and formally decided to set up a comprehensive central organ publication "Boer Sevik" in Shanghai, with Qu Qiubai, Luo Yinong, Deng Zhongxia, Wang Ruofei and Zheng Chaolin as the editorial board director (editor-in-chief). On November 14th, it was decided to set up the Editorial Committee of the Central Party Newspaper, and 21 people including Cai Hesen, Mao Zedong, Zhou Enlai, Li Lisan, Yun Daiying and Zhang Tailei were added to the editorial board.

  The first issue of "Boolean Sevik" came out on October 24th, and its title was inscribed by Qu Qiubai himself. The editorial department is located at No.418 Hengchangli, Yuyuan Road, Shanghai (now No.34, Lane 1376, Yuyuan Road), which is a "pseudo-three-story" brick and wood structure new-style Lane residence. While presiding over the Central Committee of the Communist Party of China’s work, Qu Qiubai was responsible for editing Boolean Sevik, determined to make it a "pointer to the new road of China revolution"; Every week, he will go to the editorial department from his apartment on Fuxi Road (now Yan ‘an Middle Road) to discuss topics and screen manuscripts with everyone.

  Bour Sevik was founded at the time of great changes in the revolutionary situation in China, and has opened more than 10 columns successively. In order to guard against the enemy’s destruction, it was published on the cover in disguise, and used the headlines of China Cultural History, China Ancient History Examination, Economic Monthly, Civilians and Rainbow.

  The magazine devoted a lot of space to promoting the general policy of the Party to realize the agrarian revolution and the armed uprising of workers and peasants. For example, the expansion of revolutionary forces in southern Hunan, eastern Hunan and western Jiangxi, published in the 25th issue of Volume I, introduced Mao Zedong’s establishment of a base area in Jinggangshan, reported that some troops led by Zhu De went to Jinggangshan, and praised the development of the stationed troops in Jinggangshan and the base area for making the revolution "within the reach of forces" and "the enemy dare not face it squarely". The journal also published the Central Committee of the Communist Party of China’s resolutions and instructions in time, reprinted the documents of the Communist International, and published theoretical articles on discussing and studying China’s revolutionary problems, which became an important political propaganda position of the Party. At that time, Mao Zedong asked to send "Boolean Sevik" in his letter to the Central Committee of the Communist Party of China, and said that "we are hungry for books and newspapers".

  Boolean Sevik published 52 issues from its inception to July 1932. Cai Hesen, Li Lisan, Zhang Wentian, etc. also served as the director of the editorial board. Because of the sinister environment, it gradually changed into a semi-monthly, monthly and indefinite periodical, and changed from 16 format to 32 format; During the 15 months when the editorial department was located in Hengchangli, 31 issues were published, accounting for 60%. At that time, the magazine was like a breeze, blowing away the stagnant blocks in readers’ chests after the failure of the Great Revolution. It is also like a "night light", which illuminates people’s way forward.

  Red Flag Weekly:

  First put forward "organizing armed volunteers to save the country"

  On February 17th, 1931, Zhang Wentian returned to Shanghai from Moscow, Soviet Union. At the beginning of March, he served as the Minister of Propaganda Department of the CPC Central Committee, and later became the temporary The Politburo Standing Committee (PSC) of the CPC. He adjusted the work of party newspapers in time according to the needs of carrying out revolutionary propaganda. On March 9th, Red Flag Weekly, the the Central Committee of the Communist Party of China organ newspaper edited by him, was founded in Shanghai.

  Red Flag Weekly was formerly known as Red Flag and Red Flag Daily. Red Flag was founded in Shanghai on November 20th, 1928. It was started as a weekly magazine by the Propaganda Department of the CPC Central Committee. From the 24th issue, it was changed into a three-week journal, with 16 folio at the beginning, then changed into 32 folio and 8 folio. By August 2nd, 1930, it was published in 126 issues. On August 15th, 1930, Red Flag and Shanghai Newspaper sponsored by jiangsu provincial party committee of the Communist Party of China (founded on April 17th, 1929, edited by Li Qiushi, published 385 issues in four editions) merged into Red Flag Daily, with four editions marked as "The Central Committee of the Communist Party of China (CCCPC) organ newspaper", and changed to "the Communist Party of China (CPC) Central Committee and jiangsu provincial party committee" on February 14th, 1931. The editor-in-chief of Red Flag Daily was Pan Wenyu and Wang Jiaxiang successively, and the director of the interview department was Pan Hannian. Li Lisan, Guan Xiangying and Zhang Wentian often contributed articles. The newspaper publicized the party’s principles and policies in many ways and was welcomed by both inside and outside the party. After its publication, the number of copies reached more than 12,000. Later, due to the continuous destruction of the printing house by the enemy, it was difficult to print normally. On March 8, it stopped publishing and published a total of 182 issues. It is in this case that Zhang Wentian decisively decided to close Red Flag Daily and change it into a secret Red Flag Weekly.

  The inaugural issue of Red Flag Weekly published articles such as the Draft Decree of the First National Congress of the Chinese Soviet Union and the New Plan to Break the Kuomintang’s Attack on the Red Army. Moreover, in the letter from the editor of this newspaper to the readers, which is equivalent to the publication, he appealed: "Dear readers, fight to safeguard the Soviet regime and overthrow the rule of the imperialist Kuomintang!" This newspaper mainly publishes the Central Committee of the Communist Party of China’s work reports, resolutions, policies, electricity calls, declarations, etc., reprints the documents of the Communist International, reports the news of the Soviet Union and communist party, reflects the development of the political situation at home and abroad, and guides the work of the whole party. The column "Puffy China Soviet Movement" opened by Red Flag Weekly is particularly concerned by readers. It has published a large number of newsletters and introduced various aspects of the revolutionary base areas, such as "How the Soviet Government Struggles for the Solution of the Food Problem" published by Zhang Wentian on July 10, 1932 under the signature of "Luofu", which vividly expounded the sufficient basis for the continuous development of the revolutionary base areas under the leadership of the party by combining the typical materials in several Soviet areas’ documents and reports. It is worth mentioning that after the September 18th Incident in 1931, Zhou Enlai published "Japanese Imperialist Occupation of Manchuria and Our Party’s Current Tasks" in the Red Flag Weekly published on October 21st, in which he first proposed "to lead the workers and peasants and all oppressed nations to organize their own armed national salvation volunteers", which spread the name of "volunteers". Since then, the CPC Manchuria Provincial Committee has decided to "mobilize the broad masses to establish a volunteer army".And has sent more than 200 party and league members to various places to organize or assist in the creation of volunteers.

  Due to the serious white terror, Red Flag Weekly is often in danger, but Zhang Wentian is fearless and tries his best to ensure its normal publication. The first to ninth issues of Red Flag Weekly are 8-page newspapers; Since the tenth issue, it has been changed into a 32-volume book format. In order to cover the distribution needs, it has successively adopted 16 kinds of camouflage covers such as Industry Weekly, Times Weekly, Modern Weekly, Buddhist Studies, Civilians, Modern Life and Architecture.

  In order to make Red Flag Weekly published smoothly, the Central Committee of the Communist Party of China rented two adjacent buildings (No.146-148, Lane 998, Zhoujiazui Road today) in Yuanxingli, Qiwupu Road, Shanghai in the spring of 1931, one with a secret printing factory and the other with a silk cloth village as a cover, which was specifically responsible by Qian Zhiguang. Soon, due to the mutiny of Gu Shunzhang, who held an important position in the Central Committee of the Communist Party of China Teke, the secret printing factory was moved to No.99, Meibaike Road (now Xinchang Road). A grocery store was opened on the first floor, and Qian Zhiguang, the "boss", often observed the movement outside. The second floor was used as a dormitory, and the third floor was used for typesetting, printing and binding.

  Because of the white terror, Zhang Wentian had to change his apartment many times. In 1932, he lived most of his life at No.27 Pingheli, Aiwenyi Road, Shanghai (now Lane 239, Beijing West Road). By November, it was moved to Maris New Village (now Lane 216, Chongqing North Road) located in the southwest of Happy Valley Hall. In the meantime, in addition to burying his head in his work, he also published more than 100 articles under pseudonyms such as Luofu, Pingjiang and Goth. In January 1933, he entered the Jiangxi Central Revolutionary Base with the temporary the Political Bureau of the Central Committee of the Communist Party of China. Red Flag Weekly insisted on March 1 of the following year, with a total of 64 issues and 13 additional issues. The newspaper not only played an important role as a mouthpiece, but also made a complete record of the Party’s work in Soviet areas and Kuomintang-controlled areas in the past, leaving valuable historical materials.

  Newspapers and periodicals of other central organs

  In addition to the above-mentioned party newspapers and periodicals, there are also some early the Central Committee of the Communist Party of China newspapers and periodicals published in Shanghai.

  On July 1st, 1923, Forward was founded in Shanghai. In order to deceive the enemy, it was published in Guangzhou, with Qu Qiubai as the editor and Chen Duxiu, Zhang Tailei and Xiang Jingyu as the main contributors. This magazine mainly analyzes and discusses the revolutionary problems in China, and publicizes the principles and strategies formulated by the three major congresses of the Communist Party of China. Each issue has a "inch iron" column to expose the shortcomings of current politics in short and pithy words. On February 1, 1924, it was published until the third issue was closed.

  The Communist Party of China (CPC) Party Newspaper was founded in Shanghai on November 30, 1923. It was edited by Chen Duxiu, and the periodical was uncertain. By May 1924, four issues had been published, the first of which was the document of the First Plenary Session of the Third Central Committee of the Communist Party of China, and the third and fourth issues were the documents of the enlarged meeting of the the Central Committee of the Communist Party of China Executive Committee in May 1924. The specific date of suspension is unknown.

  Central Political Newsletter (also called Central Newsletter) was founded in Wuhan in September 1926 and moved to Shanghai in November of the following year. At first, it was the most confidential and important political publication in the Party for the responsible comrades of the C.O. and the responsible secretaries of important regions to know about all aspects of work and decide policies. Later, it was changed into a public publication in the Party, which mainly published the Central Committee of the Communist Party of China documents, work summaries and local newsletters, including materials of Nanchang Uprising, Guangzhou Uprising and armed riots of workers and peasants in various places. In July 1928, it stopped publishing and published 30 issues.

  The Life of the Party was first published in Shanghai on January 1, 1929. It was an indefinite periodical at first, and changed to a semi-monthly magazine after its sixth issue. This magazine mainly publishes articles on the revolutionary road in China within the Party, and also criticizes the right-wing ideas. The main contributors are Li Lisan, Liu Shaoqi, Deng Yingchao and Yu Hongze. On June 15, 1930, the publication was stopped, and 11 issues were published.

  The Truth was founded in Shanghai on October 30th, 1930. It is a theoretical newspaper and edited by Wang Jiaxiang. The main contents published are the Central Committee of the Communist Party of China’s resolutions, declarations, circulars, documents of the Communist International on the China Revolution, and articles on the Party’s line, principles and policies. It was closed on March 5, 1931.

  Struggle was founded in Shanghai on January 21, 1932. It is a mimeographed periodical with 16 formats and was edited by Zhang Wentian. After the Central Committee of the Communist Party of China moved out of Shanghai, the journal was still published in Shanghai, with the Central Committee of the Communist Party of China’s documents and theoretical articles about China’s revolution as the main content. On July 5, 1935, the journal was closed, with a total of 79 issues published, which was called "Shanghai Edition". By the way, on February 4, 1933, Jiangxi Ruijin also published Struggle, which was a journal of the Central Bureau of the Soviet Area of the Communist Party of China. It was printed in a format of 16 pages and closed on September 30, 1934, with a total of 73 issues, known as the "Soviet Edition"; After the Red Army arrived in northern Shaanxi, on November 21st, 1935, the issue of "Struggle" was published in Yan ‘an, as the organ publication of Northwest Bureau of the Central Committee of the Communist Party of China, and later changed to the organ publication of the Central Committee of the Communist Party of China, with a total of 54 issues published in 32 format, which was called "Northwest Edition" (final issue on March 19th, 1937).

  In the early the Central Committee of the Communist Party of China government newspapers and periodicals founded or published in Shanghai, some dared to be the first, some were well planned, some were well arranged, and some struggled to open up. They adhered to the distinct political stance and the purpose of running journals, and also laid a fine tradition of party newspapers and journals.

Superbacteria

  Today, the problem of bacterial drug resistance has launched a major challenge to the global public health field.

  Every year, 700,000 people worldwide die from drug-resistant infections, and 230,000 newborns die. Studies have shown that bacterial drug resistance mainly comes from the abuse of antibiotics, including both human treatment abuse and excessive use of animals.

  Antibiotics are "double-edged swords"

  Antibiotics are a kind of secondary metabolites produced by microorganisms (including bacteria, fungi and actinomycetes) or higher animals and plants in the course of life, which have anti-pathogen or other activities and can interfere with the development function of other biological cells. At present, the commonly used antibiotics in clinic are genetically engineered bacteria, extracts from culture medium and compounds synthesized or semi-synthesized by chemical methods. If used reasonably, antibiotics are the bane of bacteria. If abused, bacteria will "immunize" it and become super bacteria, resulting in the final incurable infected person.

  Superbacteria are bacteria that can’t be killed by using all antibiotics. This kind of bacteria can show resistance to almost all kinds of antibacterial drugs, even to powerful antibiotics such as carbapenem antibiotics and vancomycin, and some of them also show multiple resistance. Because patients are often unable to produce anti-bacterial antibodies from their own bodies after infection, the mortality rate is greatly increased.

  Powerful antibiotics are usually regarded as the last line of defense against superbugs. Why is it so vulnerable? This will start with our daily medication habits. Generally speaking, we don’t have to use antibiotics in the face of common germs, but patients often ask doctors to cure them as soon as possible, so doctors will habitually use antibiotics in the face of minor illnesses. However, after taking the medicine, patients usually don’t use up all the drugs in a series of courses, and they will stop taking the medicine when their condition improves slightly, which is the main reason for the drug resistance of bacteria. In addition, excessive use of antibiotics in poultry and livestock feed is also a major cause of the outbreak of superbugs. At present, 80% of antibiotics in the world will flow into animal feed, and superbugs will be excreted with animal excrement, and these bacteria have evolved enough drug resistance in animal gallbladder before being excreted.

  For example, a salmonella that can hardly be subdued by antibiotics can easily spread between people and animals. At present, we can only passively defend against this superbug, but we can’t actively attack it. The main source of this superbug is almost all the intestines, and we are all likely to come into contact with these bacteria that were originally parasitic in the intestines. The World Health Organization admits that it is a very difficult clinical problem that Enterobacteriaceae is resistant to many commonly used and widely effective antibiotics.

  The influence affects all walks of life. In fact, bacterial drug resistance is not a problem that only exists in the health field. Statistics show that between 2000 and 2014, the standard dose of antibiotics used worldwide has increased by 50%. A research report published by the World Bank on September 19th, 2016 shows that by 2050, the medical expenses of drug-resistant infections will account for 1.1% ~ 3.8% of the world GDP. According to the current development trend, by 2050, the problem of bacterial drug resistance will kill 10 million people every year, and superbugs will also lead to global economic losses of $6.1 trillion. At the same time, problems such as labor shortage, rising medical costs and shrinking market will follow. At that time, the world economy may face a more serious blow than the 2008 financial crisis, especially for developing countries. By 2050, it is expected that the GDP of these countries will decrease by 5% as a whole.

  According to the research results of the European Bureau for Disease Control, the development speed of modern medicine is nothing compared with the speed of preventing bacterial drug resistance and bacterial variation. The resistance of human body to antibiotics is increasing, and the tools that human beings can use to deal with drug-resistant bacteria are almost used up. If market forces are allowed to allocate resources by themselves, it is impossible to complete the research and development of a new generation of antibiotics on time, and the candidates for research and development of antibiotics will be basically exhausted.

  The deadliest superbug.

  On February 27th, 2017, based on the clinical drug resistance, the mortality caused by drug resistance, the frequency of people’s infections and the burden of these infections on the health care system, the World Health Organization released the list of 12 superbugs with the highest priority for the first time. They are Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacteriaceae, Enterococcus faecalis, Staphylococcus, Helicobacter pylori, Campylobacter, Salmonella, Neisseria gonorrhoeae, and Campylobacter. The researchers classified them into three categories according to their degree of danger: emergency, high priority and medium priority.

  At present, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacteriaceae have been listed in the emergency level. These highly pathogenic bacteria will not only cause drug-resistant infections, but also bring a heavy burden to the existing medical system and take the lives of patients. Among them, Acinetobacter baumannii is resistant to carbapenem antibiotics, which is easy to cause serious infections in hospitalized patients, such as pneumonia, wound or blood infection. Pseudomonas aeruginosa is resistant to carbapenem antibiotics, which can easily lead to rash and ear infection in healthy people, and also lead to serious blood infection and pneumonia in hospitalized patients. Enterobacteriaceae bacteria inhabit human intestines and are resistant not only to carbapenems but also to cephalosporins. In 2014, among the samples of Escherichia coli (a common intestinal bacteria) collected by the World Health Organization, penicillin was ineffective in 60% of the samples, and about 25% of the samples were resistant to one or two other commonly used antibiotics.

  Enterococcus faecalis, Staphylococcus, Helicobacter pylori, Campylobacter, Salmonella and Neisseria gonorrhoeae are classified into high priority categories, and their main feature is that they are easy to cause infection in healthy people. At present, there is no particularly effective method to combat this kind of infection. The remaining Streptococcus pneumoniae, Haemophilus influenzae and Shigella are given medium priority. The resistance of these three pathogens to existing antibiotics is still increasing, among which Streptococcus pneumoniae, which is insensitive to penicillin, is easy to cause pneumonia, ear sinus infection, meningitis and blood infection.

  "Drug-resistant bacterial infections are posing a serious threat to our health care system today," said the head of the drug-resistant infection division of Wellcome Trust, a British medical charity. "The list of superbugs made this time is very important to guide the research and development of antibiotics against drug-resistant bacterial infections. If new antibiotics are not developed, 10 million people will die every year because of drug-resistant bacteria infection. In addition, if we fail to develop new drugs against deadly infections, then some treatments and means that could have saved lives, such as chemotherapy and organ transplantation, may also induce death. "

  Superbacteria ravage many countries.

  Recently, the European Bureau for Disease Control issued a warning against the current situation of bacterial drug resistance: a superbug is sweeping across Europe. In a physical examination report on animals and food published by the European Union, the name of bactericidal antibiotic clarithromycin appeared for the first time, which is almost the last line of defense antibiotic for those infected by super bacteria. Inspectors can find traces of them in animals and food, indicating that some people have easily used such drugs for some reasons.

  The report also pointed out that in the pork tested in Europe this time, the staff have found a very small number of drug-resistant Escherichia coli. If these Escherichia coli or Salmonella are transmitted to humans by pigs or cattle, then we will not have any effective antibiotics to deal with them. The report also shows that people in northern and western European countries are generally less resistant to bacteria than those in southern and eastern Europe, which is probably caused by the abuse of antibiotics.

  At present, Russia is being invaded by superbugs. Scientists have found three kinds of bacteria on the list of superbugs of the World Health Organization in 15 big cities, including Moscow and St. Petersburg. "Three kinds of superbugs were first discovered in the laboratory of St. Petersburg Institute of Children’s Clinical Infectious Diseases," pointed out Yuri Robzin, an academician of the Russian Academy of Sciences. "They can cause abscess, meningitis and septicemia. If we don’t take action now, in the next 10 to 15 years, human beings may die from the humble acne suppuration. "

  On May 26, 2016, US health officials reported that the first case of bacterial infection resistant to all known antibiotics had been discovered in the United States. The patient was a 49-year-old woman from Pennsylvania. At that time, she went to the clinic because of urinary tract infection, and the doctor used colistin, an antibiotic specially used to fight "nightmare bacteria", but the condition was not controlled. The journal of American Society for Microbiology, Antimicrobial Agents and Chemotherapy, published a report on this infection case. The report said that this superbug itself was first infected by a small DNA molecule called Plasmid, and the plasmid carried the mcr-1 gene that was resistant to colistin. "This shows that there are truly pan-drug-resistant bacteria," warned Tom Freeden, director of the Centers for Disease Control and Prevention (CDC). "This is the first case of mcr-1 reported in the United States. We face the risk of being in the post-antibiotic world. If this super bacteria is allowed to spread freely, it may’ devour’ everyone in the future. "

  Real countermeasures

  However, some medical experts have pointed out that the term "superbugs" has actually existed for many years, and some superbugs have even become very common. But in our environment, superbugs are still a minority after all, so you don’t have to panic too much.

  Facing the challenge of superbugs, we should change our thinking: instead of investing more powerful antibiotics to "exercise" them, we should let them return to the ecological competition of the original colonies. Among bacterial colonies, if there is no selective pressure of antibiotics, it will not optimize the "particularly powerful role."

  In addition, we should strictly abide by the guidelines for the use of antibiotics in clinic: try not to use antibiotics for patients with bacteria who have no signs of infection. In fact, without the intervention of antibiotics, drug-resistant bacteria are more likely to be replaced by wild drug-resistant bacteria and then disappear from the human body. Abuse of antibiotics will only "strengthen" the strength of drug-resistant superbugs while killing other bacteria. Therefore, adhering to good hygiene habits and striving to improve physical fitness are the truly effective ways to avoid bacterial infection and combat superbugs. Although the iterative update of antibiotics can control the temporary disease invasion, it also gives birth to more powerful drug-resistant bacteria. I would like to ask, in the long run, when is the head?
