It’s bad luck to "bump into the topic", let alone bump into a famous mouth in the industry. Before the "Eleventh" holiday, because of a video of 1 hour and 20 minutes or a 16,000-word evaluation, the understanding of Weilai ES8 by countless melon-eating people changed from the original simple query to the so-called "semi-finished product". Li Bin, CEO of Weilai, responded, "(These criticisms)Besides, in some places, what he said is right, although in most places, views and arguments are untenable. "

Is it a "semi-finished product"? Or "most" criticism is "untenable"? Fortunately, I have driven this car after all.

Save the old jokes for later,If you just want to see the criticism, please skip here and drop down the page to about 2/3..

90% probability of falling down? Am I one in ten?

First of all, I don’t agree with Li Bin’s statement that "most arguments are untenable"most",but in that long video/article, there are really 30%, which is obviously inconsistent with my actual feelings.

For the mechanical performance of Weilai ES8, I will give 70 points at most according to the standard of BBA luxury car. If the standard is lowered as an independent brand, then I am willing to give 90 points. The official performance data of 650 HP, 4.4s breaking 100 and 33.8m braking have been basically restored and confirmed in both positive and negative reports, so there is nothing to say.

As for what was mentioned in Test No.38,Performance shrinkage at low power.I think it is necessary to give "friends on the other side of the fuel car" a general knowledge of new energy vehicles:Electric cars, all this bird..

In fact, as early as 2016, Tesla officially confirmed: Model S.(That’s horrible)0-100km/h acceleration will slow down with the decrease of power. The Model S P100D can run an amazing 2.3s when it is fully charged, but it will drop to 3.9s when it is almost exhausted. Therefore, this is neither a unique defect of Weilai ES8 nor a common defect of Weilai and Tesla, but is determined by the innate characteristics of electric vehicles, and it is also necessary for consumers of traditional fuel vehicles to know clearly in advance when choosing electric vehicles.But electric vehicle manufacturers should really "tell the whole story" when introducing performance parameters.

In the No.38 evaluation, Weilai ES8 ran for 4.2s at 70% power and about 5s at 30% power. In comparison, in the foreign media test, Tesla Model S P100D recorded 2.3s at 100% power, about 2.9s at 50% power, and the ejection start was directly disabled at 10% power, which took 3.9s to break. Both are reasonable and normal phenomena.

As for the braking performance, the No.38 evaluation specifically mentioned that Weilai ES8 recorded a good score of 35.3 meters, but "it should be considered as normal performance because the tires are Ma brand MC6." But in fact, the positioning of MC6, that is, MaxContact 6, in the horse brand product line is not "extremely inclined to dry and grab the ground"(Evaluate the original text, the same below)",but dry land gives consideration to wetlands, high performance and comfort. Ma brand MC6 targets Michelin PS4 series high-performance tires, which emphasize performance, but all the characteristics are relatively balanced, so it tends to be dry.(Like accusing Ma Pai MC6 of being partial and Wei Lai of failing in grades? )Is not accurate.

Let’s get down to business. All of the above are just the foreshadowing. Among the mechanical performance of Weilai ES8, the most shocking thing is "great dizziness", "having a double-digit friend … great physical discomfort, dizziness, nausea and vomiting on the spot", and "the rate of being laid down is 90%, which is no exaggeration"(all are evaluation original texts).

To tell you the truth, I looked silly on the spot-maybe I drove a fake Wei? I’m the one in ten who doesn’t faint?

I know that Weilai’s mechanical calibration is not good, but I don’t know that I have entered the "No.38 Roller Coaster Evaluation Center".

First of all, it is necessary to popularize the common sense of electric vehicles in the world. Most electric vehicles, especially newer and higher-end electric vehicles, will be equipped with a kinetic energy recovery system with considerable strength. In my relatively limited electric vehicle driving experience, Tesla Model S/X is stronger than ES8, and BMW i3 is also stronger than ES8. The recovery of kinetic energy is less than that of ES8, and almost only Beiqi New Energy, which is low-end and cheap and commonly used in shared car platforms, is available.(For example, the "very cheap Beiqi New Energy EX200" mentioned in the evaluation), Jianghuai, Chery and so on.(Do not rule out the special case of missing the net, welcome to add and correct me).

This is not nonsense. When Nissan launched the second generation Leaf electric vehicle last year, it introduced its e-Pedal electronic pedal in a large space, that is, based on a powerful kinetic energy recovery system, single fuel.(electricity)The door pedal can control the vehicle. When Audi launched the e-Tron electric car last month, it proudly told everyone that 30% of the cruising range of the e-Tron depends on recycling kinetic energy, and the braking force can reach 0.3g, and 90% of the braking operation can be undertaken by recycling kinetic energy.

Everyone knows that at present, the battery life of electric vehicles is one meter more, and the stronger the kinetic energy recovery, the better.

What about the dizzy problem? First of all, in the process of driving Tesla and BMW i3, I have mastered the driving skills of this kind of electric vehicle with strong power and strong kinetic energy recovery: lifting oil at night.(electricity)Door, less brake. In the past, when driving a fuel car, you can let go of the throttle to slide, but driving an electric car requires a small step on the throttle to keep it longer.(so I will be tired). In order to ensure the safety of emergency braking, once the situation requires emergency braking, the right foot needs to move faster and more resolutely.

As a result, in the daily road driving process, after the previous "education" on other brands of electric vehicles, I can drive the ES8 so that passengers can basically not feel dizzy.

In fact, it was quietly stated in the evaluation No.38 that "great discomfort" and "90% being laid down" all refer to the specific condition of "after experiencing the sudden acceleration in the exercise mode of ES8". In the later Weibo, it was also specifically stated that 90% of the dizziness rate was "according to the working conditions I mentioned", that is, "the movement mode accelerated sharply in the middle".

I’m not dizzy, but I’m excited for nothing. I’m not one in a million. As for the routine daily commuting conditions, are passengers dizzy? No mention.

Well, ok, I have personally confirmed that if you don’t take passengers seriously, ES8 can really throw up the passengers who love to take the express train. At the beginning, I turned on the Model S P100D to start the rage mode, and it was easy to achieve 100% indifference to the stun rate. When the electric vehicle with strong power(such as Tesla, Weilai)Coupled with strong kinetic energy recovery, when driving fiercely, strong forward and backward acceleration is frequently switched, which will easily lead to dizziness. You have to put a car like you’re risking your life(high performance)When the car drives to the limit, it really makes every car dizzy. As for the so-called "(Causes of dizziness)It is not fast, but slow ",that is, the accusation that the vehicle is slow first and then fast when accelerating. Forgive me for being stupid, but compared with most similar products on the market, there is no significant difference that ordinary people can perceive.

According to the daily commuting conditions, if you have driven Tesla before, then the ES8 can basically switch seamlessly; If you have never driven a car with strong kinetic energy recovery, it will take some time to get used to it.(It’s not that I can’t drive before I get used to it, but I’m really more dizzy.). In the end, it is not difficult to achieve the "vertigo index" as low as the level of fuel vehicles, and it is not difficult to have some practical driving experience. Is this adaptation tiring? No.38 evaluation is true, as mentioned earlier, it is really a little tired. Consumers need to be clear, not limited to Weilai and even Tesla and even Audi e-Tron, all electric vehicles with strong kinetic energy recovery are like this, and there will be more and more such vehicles in the future, and they will be used to driving fuel vehicles and then turning to electric vehicles.Either adapt early or adapt late, there is no need to be nervous.

To sum up the key points:

The topic of "dizzy or not" is over.

"kinetic energy recovery priority"? Autohold is "hard to use"?

I don’t quite understand these two slots. The former, that is, when the driver releases the accelerator and steps on the brake, Weilai ES8 will directly invoke the mechanical brake system, instead of increasing the kinetic energy recovery until the kinetic energy recovery system is not enough to slow down before starting the mechanical brake. In my opinion, this is the standard mechanical priority to ensure safety first, and there is no problem.(Of course, it is far from an advantage. It is nothing more than someone spitting to attract attention.).

On the premise of having a strong kinetic energy recovery system, there will be a lot of negative acceleration when the driver completely releases the throttle. At this time, if the driver has to step on the brake pedal again, it means that the situation needs to slow down or even stop the car as soon as possible, then immediately call the mechanical brake to maximize and stabilize the braking force. I don’t think there is anything wrong with it in theory, but I don’t feel it in practice.(Compared with other brands of electric vehicles)What’s different.

Again, in terms of kinetic energy recovery, the ES8 is not much different from electric vehicles such as Tesla and BMW i3.Everyone is about the same.. Of course, it’s not that "what Tesla does is right", but that this feature may not be to everyone’s taste, but it’s exaggerated and unfair to describe the common features of this electric car as the shortcomings or even defects of a certain car.

As for "there is no N gear, and the Autohold function is difficult to use", Wei Lai told us during the test drive that the use method is: short-term parking and deep braking to turn on the Autohold, and long-term parking and engaging in the P gear.(with hand brake). Autohold is turned on and off by stepping on the brakes deeply, that is, just stepping on the brakes directly, which is different from many other brands.(including some fuel trucks)Autohold is used in the same way. The so-called "Autohold intervenes differently every time according to the brake pedal pedaling intensity" and "it’s difficult to use", I failed to understand: just pedal to the end, do you have to test the small "pedal critical interval" where Autohold intervenes or not?

Control and chassis, rare recognized advantages.

In the full text of the 16,000-word evaluation, there are very few points that praise ES8, among which use"Give praise"(original)Three words, is the suspension system of ES8. If the car is judged by the strictest standards, there is only one advantage left in the end, and that must be the chassis and suspension-not the power, not the NOMI.(Of course not, spit later), not the queen’s copilot …

Our test drive includes a section of mountain road around the lake. I basically go at a speed of 60-90km/h when cornering. If it’s not a blind corner, I will have full oil and full braking: this should be properly regarded as a category of "intense driving". Of course, the premise is that the road conditions are simple and familiar, which can ensure safety.(BTW, practice shows that passengers will be 100% dizzy when driving this way. )

The so-called "the dynamic characteristics of vehicles are strange when approaching the limit" may be that I am stupid, but I didn’t feel "strange". The roll control of the vehicle is quite good, and the support given by the front suspension in the corner is also sufficient. The natural low center of gravity of the electric vehicle may also contribute. It gives me a feeling a bit like opening a new A8L on the roundabout road in Sanya in March, not boasting that the ES8 is comparable to Audi, but that the character of this kind of vehicle to take care of the road for you is somewhat similar. The steering feel, road feedback and righting strength of the ES8 are not as good as those of BMW, but if you have low expectations for electric vehicles before, such as Beiqi Jianghuai Chery, which is common in sharing cars, it should be able to give you a little surprise.

The same is true for vibration reduction, but it is slightly different from the "good handling of large vibration" in the above evaluation. ES8 is more comfortable to handle small road undulations, such as the slightly sunken manhole cover that is common on the road, which can basically pass quietly under the condition of "painless" passengers. For big obstacles such as speed bumps, ES8 is more conventional. On the whole, this performance is not comparable to BBA, at least in domestic independent brand cars. If combined with the support performance during intense driving, the suspension system may be the most likely place to leave a good impression on the ES8.

What about the shortage? When driving on the highway, the small steering of the ES8 has a negative effect. In the high speed of about 200-300 kilometers, there are indeed cases where the direction needs to be slightly revised frequently. At first I thought it was following the car for a long time.(Driving in formation)As a result, I failed to look far myself. However, on reflection, there are indeed some problems with ES8. Under the three driving modes, the steering wheel strength of the ES8 is not obvious, and they are all sensitive, which will make your fatigue increase faster when driving at high speed for a long time.(However, the power of the ES8 … it seems that there is no "long-term high-speed driving").

Product defects? Not really, the adjustment of the direction feel is not perfect, which is a small but reasonable demand for a new brand. However, the so-called "three modes can be defined as difficult, extremely difficult and super-fucking difficult". I must say that I have never felt "difficult to use" under such a description scale, and I don’t know how I got such a degree of emotion and disdain. If the steering feel of this car can be defined as "super * * difficult to use", then the double-digit models in China auto market can only be described as unspeakable foul language.

The more urgent need for improvement is noise control, especially at high speed.ES8 will not give you the feeling of "the electric car is silent" at all.. Low-frequency mechanical noise and subtle vibration always exist, but it seems that the performance of wind noise seems quite good. If a passer-by who eats melons is asked to do a double-blind test, there is at least a 70% probability that he can’t guess that this is a pure electric car.

Passengers will feel more comfortable at low speeds. Weilai claims that the torsional stiffness of the body of the ES8 is twice that of the Model X. When it is impacted at a low speed, the ES8 will not have the same kind of car-such as the Model X, such as the abnormal interior noise of the previous generation BMW X5. The overall feeling of the body and the feeling for passengers are better than many models of the same size.

Endurance and battery change, shortcomings and disputes

Unlike many people who eat melons, Wei Lai is actually quite frank about the short battery life of the ES8. Long ago, they released the official cruising range calculator, in which the high-speed cruising range of 120km/h was clearly marked as only 236km.(20℃, air conditioning off, 21-inch wheel hub). In this test drive, I simply counted, cruising at an average speed of about 110km/h, the battery life of the meter decreased by 51km and the odometer increased by 38km.(32℃, air conditioning 23℃, 21-inch wheels)It is basically in line with the endurance level of high-speed 200km+.

For real users, the cruising range of electric vehicles should be "discounted" on the basis of this discount. Because, after all, unlike driving a fuel car, there must be a gas station in Fiona Fang every few kilometers. Electric cars need to drive at least several kilometers to find public piles, or they need to rush back to their homes where they often go for 10 kilometers. To be on the safe side, they need to leave at least 10-20 kilometers of mileage. So in a word, ES8 can actually be used in the cruising range on the road. Generally speaking, 290±20km in urban area and 200±10km in high speed are more reliable references.

The actual cruising range of electric vehicles will definitely be smaller than the NEDC standard cruising range, which is also the necessary common sense for fuel vehicle users to switch to electric vehicles. Up to now, the endurance of the ES8 is no secret, and the data about 300km in the urban area and the early 200km at high speed are relatively reliable. Of course, the premise is the non-cold environment, the air conditioner does not turn on the extremely low temperature, and the driving habits are mild. If I hold the mentality that "it won’t cost a few dollars to power up anyway", I will have to charge when I drive the Model X 100D for more than 200 kilometers, which is a NEDC car with a mileage of more than 500 kilometers.

As for a series of problems brought about by power exchange, it has been discussed in the previous "Weilai IPO rings the bell tonight, where is the road of" 3-minute power exchange ". Weilai officials also confirmed that the ES8 chassis space is indeed available to ensure that all models of the brand have universal battery packs. As an "exchange", the laying of Weilai Power Station is still in progress.

For the power exchange station, Wei Lai disclosed some technical details this time:

There are still many questions about Weilai’s power exchange station, and the most typical one is that "the loss of new batteries caused by power exchange is greater than that of original batteries" and the resulting derivative problems. In addition, we also want to know the landing difficulty of Weilai Power Station in laying, such as whether there will be obstacles in facing the fire department. And the user level, can the owner choose a single power change?(Currently included in Weilai’s "Worry-Free Energy" service package)How to calculate the single price, how to use the power exchange station for the owner of the whole vehicle with battery, and so on.

As of mid-September, we have learned that the number of power stations in Beijing has increased to six. When Li Bin opened a store in Chengdu a few days ago, he mentioned that he would speed up the deployment of power stations around the expressway. "The company will give full play to the inherent advantages of Weilai Automobile’s structure.(Exchangeable). As mentioned in the last article, whether Weilai can successfully and timely land the power exchange system will have an important impact on Weilai’s next development.

Weilai has been wasting a lot of time on the "one-click power-on" service, but the fact is that everyone knows that this uneconomical and inflexible way is not a long-term solution. If electric vehicles really want to reach the majority of people and the broader market, they will eventually rely on recharging.(Charge & Exchange)Perfection, normalization and scale of facilities. Not long ago, Weilai supported some users to drive ES8 in Xinjiang, and as a result, it was criticized for "scooter dragging charging car". Even Weilai himself knows that in the future, the mobile charging car will only be a supplementary part of the whole NIO Power system, but at this stage, other charging facilities are not mature enough, so they have to take on more charging tasks.

Picking holes? Queen’s copilot, NOMI, big screen UI…… …

It’s common for people who sing bad songs to complain about ES8, that is, there are too many gimmicks. I subjectively understand that Weilai, as a new brand, is the first new car that dares to position itself as a "luxury brand". Strategically, it needs to create selling points in all aspects. But objectively, some of these patterns of ES8 really seem to be more gimmicks than reality.

A typical example is the Queen’s copilot. I have to say that Weilai knows the car habits of Chinese people very well. In the past, this kind of semi-reclining seat only appeared in the right back seat of executive-class cars, and even SUVs with the same price were mostly lacking. Wei Lai clearly realized that for China families who drive by car, the co-pilot is far more important than the right back seat, and this design idea is worth encouraging.

However, on the ES8, perhaps due to the cost limitation, the use steps of the Queen’s copilot are a bit cumbersome, so it is hard for me to imagine who will use it frequently. You need to adjust the three electric switches on the right side of the seat cushion, put down the foot rest-raise the leg rest-and level the back of the chair. There is no key in place and no position memory. It is up to your right hand to keep pressing a switch to determine the tilt angle. If you want to maximize the legroom, you need to toggle another manual switch on the right side of the seat cushion, and then move your hips to make the seat move back greatly.(i.e. parent-child mode). The recovery method of foot rest is also manual or manual.

To achieve the best comfort of leaning back greatly, this operation takes at least half a minute, and the right hand does not stop all the time. It’s not so much the queen’s co-pilot, but rather the sleep-supplementing co-pilot: it’s not cost-effective not to sleep once. Indeed, it is too suitable for sleeping, and my right media colleague in the same car personally verified it. The question is, having achieved such "meticulous", why is there a lack of "one key in place"?

If you choose the standard version of ES8 now, NOMI is an option worth 4,800 yuan, which is good news in reality.

It is absolutely unfair for NOMI engineers to "put a little love classmate in the car". When you get into the car for the first time, it turns its head and smiles, which will give people a good impression emotionally. However, compared with the current intelligent voice assistant(Not limited to vehicle)Similarly, NOMI can’t have the intelligence beyond this era, which also determines that it can’t be as considerate and powerful as the promotional film in many cases. However, ES8 relies too much on NOMI, which will bring problems.

For example, ES8′ s panoramic sunroof switch is not a common two-stage switch, that is, it can’t be opened and closed with one button, and it must be held by hand all the time when it is fully opened, or-call NOMI voice to give instructions. But as we said before, the female throne of the ES8 is very easy for the co-pilot to fall asleep … If you want to close the skylight at this time, you can only work hard for yourself-this inconvenience will not appear in traditional luxury cars.

There is a similar situation. For example, there is no physical switch for seat ventilation and heating.(After all, it is normal to have a big screen.)However, their UI switches in the central control screen are hidden in the air-conditioning interface and need to be adjusted in the 3rd floor menu. This means that if the environment is inconvenient for you to call NOMI by voice, the only choice is to click the screen once and for all. Perhaps Weilai’s UI designer will think "it doesn’t matter that there is NOMI", but the fact is that it is not uncommon for drivers/passengers to make noise.

In terms of intelligent interaction, NOMI has indeed not surpassed the times. In quiet environment, it can accurately recognize speech, but there are too many noisy times in the car. The whistle outside and the conversation between relatives and friends in the car will affect the recognition accuracy of NOMI.(Of course it’s not NOMI’s fault). In addition, the ability of continuous dialogue is not brilliant. If the recognition fails, you need to call "Hi NOMI" again and start over. In short, NOMI is not weaker than most similar assistants, but intelligent voice assistants are still unable to undertake and should not be given too many tasks.

During our short test drive, there was also a bug that NOMI black screen crashed and did not respond, and it didn’t return to normal until it was restarted after turning off the car. This does not affect driving like a more serious bug, but it also shows that NOMI should not act as an important operation mode.

Vehicle OTA and privacy security

These two points should be the least controversial in the 38 th evaluation. Vehicle OTA(FOTA)For the challenge of the stability of the on-board system, in the following ES8 owner @ Yadong(Weibo)Exposed in the crash bug encountered. As mentioned above, I have also encountered a small bug of NOMI black screen crash.

This is actually easy to understand. Generally speaking, the development cycle of a new car is as short as three to five years and as long as longer. During this period, the software and hardware of the whole car will be tested for a long time and gradually finalized. When the feasibility of OTA appears, the updated firmware may only go through a few months of real vehicle testing. Although manufacturers always claim that they have passed strict and perfect security tests, considering that Windows developed by thousands of top engineers in Microsoft still can’t move the blue screen, Apple’s stable iOS will inevitably appear "white apple". Ordinary users who don’t know anything about computer code have any reason to believe that more complex vehicle firmware can be foolproof?

Not only ES8, but also Tesla, the promoter of vehicle OTA, has bug problems. Coincidentally, the Model X test drive I met in my last company actually encountered the bug of the crash of the central control panel. The problem is not as serious as that of the ES8 owner, but it also shows the challenge of OTA upgrade to system stability. OTA should not be rejected, but it should not be rushed.It is even more impossible to use "OTA can quickly fix loopholes" to ignore the premise fact of "why there are loopholes in vehicles".

In May of this year, Tesla Model 3 was criticized by Consumer Report for its braking problems. Later, Tesla discovered that it was a vehicle software problem, and the emergency OTA upgrade firmware was solved. Although this is OTA’s contribution, it cannot be ignored that Tesla has a major fault in software defects.

Back to ES8, in mid-September, Weilai released "Developed day and night"(Uygur)Version 1.0.8 firmware, and said that this will be the last large-scale offline update. It is this version 1.0.8 firmware that will enable the ES8 to have the OTA capability of the whole vehicle, that is, the owner will be able to write the new firmware by himself, thus upgrading the core system of the vehicle.Security and stability are the first,I hope this will be the last time for Weilai firmware development team to "travel day and night"(except, of course, fixing bugs).

Privacy is another big problem. Past experience and lessons tell us that the threat to users’ privacy is inevitable and severe when everything meets the word "intelligence", not just cars. In fact, compared with Tesla, domestic new cars, and even some new models of traditional car companies, Weilai’s external sensors need to collect no more information. As for the so-called Weilai Club collecting passenger conversations, it is also stated in the privacy agreement that "the system may collect them when NOMI is turned on", that is, it may be recorded when calling NOMI. However, in the ES8 car, this camera, which was originally used for passengers to take selfies, brought people much more discomfort. In particular, it is also a super wide-angle lens, which can clearly take a panoramic view of the car.

A very simple example, in 2016, a photo of Facebook CEO Zuckerberg’s desk caught public attention. His Macbook front camera was taped. Obviously, even the top IT companies in the world can’t completely eliminate risks, and a piece of tape is the simplest solution. For Weilai ES8, it is really necessary to add physical shielding such as baffle to the camera in the car. It adds a very small cost, but it fundamentally reassures users.

As for other information collection behaviors, such as the address, mobile phone address book, music playing and a series of information in the car system, Weilai’s "eyes and ears" are indeed a little far. Although we are willing to believe in Weilai’s integrity and management level as a big company, users are objectively in an information asymmetry position, and what they need is privacy and security that they can confirm. When consumers choose goods, of course, there are also elements of choosing values. "Consumers who don’t agree with values can not choose this car." Then, from another perspective, enterprises whose values are inconsistent with society will not be recognized by consumers.

ES8 also has some small advantages, such as the display area of HUD is much larger than usual, and there is basically no need to look down at the instrument when driving on the speed limit section; The front central control and lower package place, the front armrest box are large and deep, and the rear central passage is completely flat, which gives full play to the advantages of electric vehicles; There are also air outlets on both sides of the rear roof, which is more stereoscopic for the air conditioning of the rear passengers.

What about the criticism of ES8? Look at it in several ways. The driving performance is not perfect, and the ES8 is indeed immature with distinct advantages and disadvantages. But as far as the short-term test drive is concerned, its shortcomings are not beyond the degree of "imperfect adjustment", and it is not as shocking as the so-called "semi-finished product".

ES8 has an excellent chassis and suspension system, and its powerful power and brakes are solid. Due to the common kinetic energy recovery system of electric vehicles, it is really easy to cause dizziness when driving fiercely; The steering texture has reached its due level, but the stability at high speed still needs to be tempered; As for battery life, it is already a shortcoming that official website admits in disguise, and it needs Weilai to speed up the construction of charging and replacing system to make up for it.

More slots come from in-vehicle and in-vehicle systems. The UI of the car’s big screen failed to find a balance between beauty and convenience, and NOMI, which has no actual substitution function, was given too much responsibility. Coupled with occasional system bugs, large and small, at least at present, ES8 can’t guarantee to give users a 100% complete, 100% stable and 100% easy-to-use in-vehicle system, which requires Wei Lai to calm down and take safety and stability as absolute goals in stages.

Small slots include some unreasonable facilities in the car, for example, the skylight does not have one-button opening and closing, for example, the UI menu design still needs to be considered, for example, the queen’s throne is designed without one button in place. These are not serious shortcomings, but they will eventually affect the user experience. If manufacturers pay attention to them, it is easy to improve them in the next generation of products. At the same time, some small advantages should not be ignored, such as the improvement of the position of the co-pilot, such as a large-scale HUD, such as a series of rethinking of storage space.

There is no doubt that OTA and privacy security are re-examined. Although these are new technologies that exist in many so-called "future" cars, we should not treat each car factory with the mentality of "the law does not blame the public". The advantages of vehicle OTA are obvious to all, but at the same time, the challenges to safety still need to be carefully considered by every manufacturer. Once you choose the road of OTA, you must accept the challenge of stability and security. Consumers don’t need to care about how many kilometers have been tested and how many days and nights have been developed. Whether the final result is good or not and there is no bug is the only test standard.

Privacy security is even more so. "It is difficult to protect privacy in today’s society" is not an excuse for a certain manufacturer’s inadequate privacy protection. In Weilai’s privacy agreement, there are indeed a considerable proportion of terms that are not beneficial to users, and users obviously have no responsibility to help manufacturers develop and test, let alone risk that privacy may be leaked. In-car cameras without any physical shielding can easily cause some privacy-sensitive users to be nervous and uncomfortable.

Generally speaking, ES8 is the first work of Weilai, a new brand. If this identity is taken into account as a prerequisite, the answer to this paper is satisfactory. But for ordinary consumers, they have no reason and no responsibility to lower their standards.

So, regardless of this identity, judging by normal standards, ES8 does have some shortcomings and immaturity in many aspects, but the description of "semi-finished products" is somewhat sensational. For example, many "defects" in machinery are actually common in most electric vehicles and should not be defined as the defects of ES8 individuals. More importantly, these so-called "defects" are not serious enough to affect health and safety in daily use. They should be defined as the shortcomings of the ES8 as a car, rather than the "product defects" exposed by the so-called "semi-finished products".

As for the above shortcomings, you should have a good idea by now.(Please capitalize and bold the word "shortcomings").

After graduating from the police academy, Yuan Zijie returned to his hometown Liulin and became a criminal policeman. Shortly after entering the police, he cracked the case of Wang’s gang robbing a taxi.

"This kid does have two brushes." Li Qiutian, then the squadron leader of the Second Squadron of Criminal Police of Liulin County Public Security Bureau, made no secret of his appreciation for Yuan Zijie. Since then, Yuan Zijie has become one of the elite police forces that the county bureau will deploy every project. Although the criminal police brought Yuan Zijie a sense of accomplishment, he always remembered his grandfather’s words: "The countryside is a good place, with a vast world and great achievements."

In 2002, in order to exercise himself, Yuan Zijie gave up his job in the criminal police team of the county bureau and applied to be a grassroots policeman in the Mengmen police station with the most difficult conditions. In 2012, he served as the instructor of Liuyu Town Police Station. For more than ten years, I have been rooted in the mountainous areas and dedicated my youth to the people in the mountains.

"It’s not easy for people in mountainous areas. It’s a help. Go, dad supports you! " The support of his family encouraged Yuan Zijie.

On New Year’s Eve, when Yuan Zijie first arrived in Mengmen Town, there was a case of picking quarrels and making trouble in the local area. After receiving the police, Yuan Zijie and his colleagues immediately went to the police and launched an investigation. 12 inquiry materials were sorted out overnight, and 6 illegal persons were administratively detained. On New Year’s Day, Yuan Zijie and his colleagues cooked some dried noodles at the police station after a busy night, thus spending his first Spring Festival at the grassroots level.

People in mountainous areas have been farming for generations, and they don’t pay attention to the registration. Living in the most remote tower village in Liuyu Town, there is a father and son. In 2012, after Yuan Zijie learned about the situation of the father and son during his visit, he immediately began to investigate and collect evidence and reissued the account for the father and son. Since then, the father and son can receive 4000 yuan compensation every year, and also enjoy old-age insurance and medical insurance.

During more than three years in Liuyu Police Station, Yuan Zijie has reissued accounts for 2,722 people.

"This Eva is really good! Willing to do things for the masses. " Anyone who has dealt with Yuan Zijie will give a thumbs up. Over the years, Yuan Zijie insisted on the convenience service, and delivered more than 1,000 certificates to the elderly over 70 years old, which was well received by the people in mountainous areas.

On July 18, 2012, more than 100 migrant workers from Jiangsu province reported that their wages of more than 900,000 yuan could not be cashed. He learned more about these 100 migrant workers’ brothers in detail, obtained evidence from many parties, consulted materials, and repeatedly negotiated with the contractor to persuade them. In the end, both sides were moved by his sincerity, and more than 100 migrant workers’ brothers successfully got hard-earned money and sent it to a plaque with the words "Liulin police warm people’s hearts, Jiangsu migrant workers are deeply grateful".

An expert in criminal investigation keeps one side safe.

When the Ministry of Public Security launched the "Clean-up Action", Yuan Zijie took the initiative to fight, and thoroughly investigated the fugitives in the area one by one, and cleared all the fugitives in the area.

It is worth mentioning that when Liu, an intentional murderer who had absconded for 16 years, was arrested on Mid-Autumn Festival night in 2011, in order not to leave a psychological shadow on Liu’s young children, Yuan Zijie suspended the opportunity to arrest him and held on for one night. The next morning, he and his comrades-in-arms successfully arrested Liu while his children were in school. Liu, who learned of the incident afterwards, was completely influenced by Yuan Zijie and was willing to plead guilty.

In the past 16 years, Yuan Zijie has detected 139 criminal cases and arrested 157 suspects. 246 cases of public security were investigated, and 273 offenders were punished. The incidence rate of criminal cases in the jurisdiction is decreasing year by year, which greatly improves the people’s sense of security and satisfaction.

Due to his outstanding work performance, in April 2014, Yuan Zijie was awarded the honorary title of "Shanxi Model Worker" by the Shanxi Provincial Committee of the Communist Party of China and the Shanxi Provincial People’s Government; On October 28, 2014, he was awarded the honorary title of "National Model of Public Security Organs Caring for the People" by the Ministry of Public Security, and took the stage as an award-winning representative to accept the award from the central leadership. He was cordially received by the party and state leaders such as the Supreme Leader General Secretary and took a group photo. In January 2015, he was awarded the honorary title of "the second-class hero model of the national public security system" by the Ministry of Public Security. He is the only advanced individual in Liulin County who has been awarded this honor by the Ministry of Public Security since the founding of the People’s Republic of China. In February 2015, Gao Piao was selected as one of the top ten "Most Beautiful Lvliang People" in the "Most Beautiful Lvliang People" selection campaign conducted by the Propaganda Department of Lvliang Municipal Committee and Lvliang TV Station. In August 2015, he was elected as the candidate of "China Good Man" by the Propaganda Department of Shanxi Provincial Committee of the Communist Party of China; In October 2015, Yuan Zijie’s family was awarded the nomination family award of "the most beautiful family in Sanjin" by Shanxi Women’s Federation; In April 2016, he was rated as "Advanced Individual in Network Security Work of Public Security Organs in Shanxi Province" by Shanxi Provincial Public Security Department.

Hold a dream and hold up a sky. The relationship between the police and the people is like fish and water. Fish cannot live without water, and the police cannot live without the masses. Yuan Zijie revealed his magic weapon: only by having a heart-to-heart relationship with the masses can our work be carried out smoothly; Only by communicating with the masses can our cause flourish; Only by communicating with the masses can our dreams be within reach. He has fallen in love with the land and people where he works.

　　　　With the continuous improvement of the upgrading speed, the mobile phone configuration is also constantly refreshing the record. Ten-core processors and 4K screens have already appeared, and even the running memory has been upgraded to 6GB last year. At this year’s CES 2017, let’s see the debut of the first 8GB running memory mobile phone. In the past, 4GB was called Little Monster Level, so what is the concept of 8GB now? Today we will talk about 10 things about the running memory of mobile phones.

8GB is here. Does the mobile phone really need such a large storage?

　　　　1、How is the 8GB mobile phone stored? "come"?

　　　　There are many factors for the development of mobile phone running memory, the most important of which is the support of mobile phone SoC for mobile phone running memory. When the 64-bit processor began to be used, the smart phone officially announced that it had entered the era of 4GB running memory. With the advent of Qualcomm Xiaolong 820 processor, it supports up to 6GB of running memory, while Qualcomm Snapdragon 821 processor supports 8GB of running memory, and Samsung officially mass-produced 8GB of RAM particles. Hardware conditions allow, and 8 GB of running memory will naturally come.

　　　　2、What exactly is the running memory of a mobile phone?

　Dream is the first Android phone with 192MB of running memory.

　　　　If memory is mentioned, the first thing that users should think of is storage memory. When buying a mobile phone, they will first ask how big the memory is and how many "things (APP//blockbusters)" they can hold. Generally, the size of running memory is not asked. Running memory refers to the memory when the mobile phone runs the program, also called RAM (referred to as transport memory). In short, in theory, the larger the running memory of the mobile phone, the smoother the system runs.

　　　　3、Will the memory conference not have the problem of "excess" like the processor?

The first mobile phone with 1GB running memory-Samsung Galaxy SII

　　　　The running memory of a mobile phone is not like a processor. In a sense, there will be no "excess" problem, because as long as you open more applications, how much running memory will be filled, so there is no such problem as the processor.

　　　　4、How much storage does Android phone take up in daily use now?

Mobile phone system and daily multitasking occupy a lot of running memory.

　　　　Since the first release of Android Beta in 2007, after nearly ten years of continuous evolution and upgrading, the system has occupied more and more memory. From the original 1.0 native system only occupied 100M of memory, to the present 7.0 system occupied nearly 2GB of memory, plus various apps used daily, taking a 4GB mobile phone as an example, there may usually be only more than 1GB of running memory left.

　　　　5、Why is the Android phone stuck when it is used?

LG Optimus II is the first mobile phone with 2GB of memory.

　　　　"Caton" has always been a pain point that Android mobile phone users have to face. Speaking of the Android system, the mobile phone is stuck. In fact, this has a great reason with the mechanism of Android. Android and iOS are very different when dealing with garbage collection. Android’s garbage collection mechanism needs extra memory for garbage collection. When an Android application ends running, the mechanism needs more memory than it to recover the memory occupied by the application. In addition, more and more mobile phone programs are installed, the function of mobile phone APP is becoming more and more powerful, and the demand for ROM and RAM is becoming more and more powerful. Over time, mobile phones begin to get stuck.

　　　　6、How to clean up the special garbage of Android and iOS phones?

Samsung Galaxy Note 3, the first smartphone with 3GB of memory.

　　　　The special garbage collection mechanism of Android phone is similar to the eraser principle. A piece of white paper is full of dirt, and the eraser is erased word by word. The advantage is to accurately remove the dirt and keep the content needed on the paper. The disadvantage is that the recycling mechanism is slow to process. Once a large number of different Android applications run, the problem will follow. If the memory of Android phone is not enough to call this mechanism, the running speed will slow down. IOS has done a lot better in this respect, tearing off the dirty paper and opening a new page, which is fast, but when users switch back to these applications, they will experience the waiting process of restarting.

　　　　7、With a large amount of storage, Android phones will run faster?

The first smartphone with 4GB of running memory-

　　　　If the processor of Android phone has strong performance (speed up processing) and large memory capacity, it will have a unique advantage. It can ensure a large number of simultaneous operations, and the large memory capacity is convenient for the "Android garbage collection mechanism" to call memory, so that the system can maintain a relatively smooth state. And the user switches back to the previous application and remains in the last intact state.

　　　　8、What is the relationship between GPU performance and running memory?

Mobile phone GPU operation occupies running memory space.

　　　　Different from PC, smart phones often don’t have independent graphics cards, because the size and heat dissipation of mobile phones are limited. In other words, the GPU of the mobile phone also needs to call the running memory, so it is necessary to increase the capacity appropriately. At the same time, with the improvement of screen resolution, demand, and even popular virtual reality applications, mobile phones are required to have better graphics capabilities. In addition to the performance improvement of GPU, the larger the running memory, the better the performance of GPU.

　　　　9、Is it really necessary to equip a mobile phone with 8GB of running memory?

The first smartphone running 6GB of memory-

　　　　With the continuous expansion of smart phone functions, the volume of systems and applications will become larger and larger. More and more systems and applications will force mobile phone manufacturers to constantly upgrade their memory, which is a process of mutual promotion and spiral rise. Simply put, when 6GB is widely used, the demand for memory of systems and software will be further improved, and it is very necessary to store 6GB at this time. The same is true when 8GB of running memory arrives.

　　　　10. What is the relationship between the standard of LPDDR and running memory?

Development process of mobile phone memory standard

　　　　LPDDR is a kind of DDR SDRAM, which is a communication standard for low-power memory formulated by JEDEC solid-state technology association of the United States. In short, mobile phone memory particles are calibrated by this standard. The LPDDR RAM used in mobile phones is the abbreviation of "low power consumption double data rate memory", while the current LPDDR R4 for mobile platforms can bring equivalent performance (speed) and take into account less energy consumption. In addition, compared with the previous generation standard LPDDR4, two new features are double data rate and low power consumption; That is to say, the speed of speaking is 50% faster and the power consumption is low.

　　　　Write it at the end

　　　　In order to meet consumers’ pursuit of performance and the continuous expansion of mobile phone functions, mobile phone manufacturers have been upgrading processors and improving running memory. The memory of a mobile phone is like a driveway on a highway. The more and wider the driveway, the smoother it will be to drive, so the greater the operation of a smart phone, the smoother it will be to use. In addition, it should be noted that when you buy a mobile phone, you should not blindly pursue the absolute size of running memory, but also look at the remaining space under normal use of the mobile phone.

　　　　That’s all for today’s talk about the running memory of mobile phones. You are welcome to leave your views on the running memory of smart phones in the comments section.

　　Our reporter Li Xiazhi

　　"Fall in love? Destroy your whole family. " If you haven’t seen the recently hit online drama "East Palace", maybe you simply can’t understand a large number of new quotations such as "finding candy in the glass slag" invented by these self-proclaimed "East Palace girls" when chasing the drama. At the same time, another online drama "Falling in Love with the Big Dipper Boyfriend" with a completely different theme has become a "sweet pet drama in online celebrity" which has attracted much attention from netizens recently, because the plot of "making sugar" between the protagonists is so sweet and greasy that it is off the charts. The trend changes rapidly, the youth idol drama turns to the collective, and young people are keen on the relaxed and happy theme of "love brain", which is "collusion" between society and industry to some extent.

　　More than a dozen movies a year, "sweet pet" has become a new trend.

　　Since last year, the types of online drama explosions have begun to turn, and suspense and thriller themes have changed lanes. In 2018 alone, more than ten "sweet pet dramas" have been launched. From "Two-time Spoiled Princess 2" and "Love the First Love of Chitose Adults" to the recently broadcast "Why BOSS wants to marry me", "East Palace" and "Love the Big Dipper Boyfriend", the sweet interaction between the male and female protagonists has become the highlight of the plot. It seems that "kissing and hugging and holding high" is very popular among Internet audiences. For example, "Two-time Spoiled Princess" with a low cost and a brand-new lineup once created a record of 3.6 billion plays, and "Why BOSS wants to marry me" also quickly attracted network traffic, and the attention was once overwhelmed by "Biography", a sequel to "Story of Yanxi Palace" in the same period.

　　This trend is not unique to domestic online dramas. "Life is hard. I eat sugar with my mouth open and stick to ‘ Sweet pet ’ The film and television works of the label are popular in China, Japan and South Korea. In terms of Korean dramas, last summer’s "Why is Secretary Jin like that" and the recent hit "Touching the Heart" have made many viewers feel full of sweetness. " Drama critic Dai Taojiang pointed out that "Touching the Heart" is still at the top of the list of recent Korean dramas, although the plot itself lacks new ideas and just "sends candy" on the protagonist’s love bridge. At present, the number of official Weibo readers of "East Palace" has exceeded 2.1 billion, ranking second in the super-topic community, and only last year’s "explosive drama" Zhen Soul of Youku can rank ahead of it.

　　Even though Li Chengyin and nine princess Xiaofeng, the protagonists in the East Palace, are in love with each other, the story of sweet pet comes to an abrupt end because of the reversal of the fate and personality of the characters in the later period. Many viewers can’t accept it, calling for the story to continue to "distribute sugar" in the barrage, and even giving the play a nickname "Hua Mei Drama" (referring to the tragedy that the hero and heroine are crazy about "spreading sugar" and the audience can’t stop).

　　Subdivide the audience and aim at "light" women

　　"Sweet pet drama is a branch of traditional romantic comedy, and its success in the market benefits from the high certainty of this type." Dai Taojiang said that compared with the traditional romantic comedy, the protagonist’s emotional evolution may go through various hardships, while the sweet pet drama is "sweet" from beginning to end. "The heroine is the first and only emotional hero, and the heroine is the absolute winner in the emotional relationship. All that is needed in the process is the romantic experience brought by the hero." In her view, this highly deterministic structure and setting satisfies the mentality of some viewers to watch easily, and the audience can get great psychological satisfaction without putting too much emotion into it.

　　For the market, this type of drama that directly hits the audience’s preferences is precisely the audience segmentation and precise positioning pursued by the current online drama. Naran, a drama critic, was shocked to notice that the audience around him who loves to watch sweet pet dramas are mainly female audiences after 1980s and 1990s. For most young women, romantic love dramas are a spiritual supplement to reality. "If the emotional needs in real life are not met, at least you can get a good mood by watching sweet pet dramas."

　　According to Tencent’s 2018 Index Report, Tencent’s video drama-chasing users account for 54% and 18% after 90 and 00, respectively. The proportion of program users under the age of 24 has increased from 51% in 2017 to 55%. The post-95 and 00 generations with diverse tastes have gradually become the main audiences in all dimensions, and the user groups tend to be younger. According to the data published by various video websites, the user base of video websites is still dominated by women. Ying Dai, vice president of Aiqiyi and general manager of the self-made drama development center, also said that taking Falling in Love with the Big Dipper Boyfriend as an example, Aiqiyi focused on "light-cooked" women in her era to launch light-cooked sweet comedies, which was an extension to more vertical subdivisions under the broad theme of youth. It is not difficult to get the favor of producers and platforms for sweet pet dramas aimed at young female audiences.

　　"Sending sugar" is illogical, so be alert to aesthetic fatigue.

　　From Yunxi Hug in Yunxi Zhuan, Wei Long CP in Story of Yanxi Palace, to gratitude in Sweet Honey as Heavy as Frost, there are more and more sources of sweet pet dramas, but the means are slightly single, which also brings "too sweet" and "too tired of sweet".

　　“‘ Sweet pet ’ It mainly relies on daily interaction and intimacy to create an atmosphere, which has extremely high requirements for the face value and romantic bridge setting of male characters in the play, and also puts forward certain requirements for the audience of actors. " Dai Taojiang has no doubt that many producers have seen the market prospects of sweet pet dramas, but failed to see the structural and plot defects that such dramas often bring to satisfy the "sweet pet". "Most of the sweet pet dramas have logical flaws in the relationship construction, the characters do not have basic action logic, and many plot settings seem blunt and abrupt. In addition, the means of sweetness and pampering in intimate relationships are nothing more than infinite tolerance and intimate contact. Over time, it is easy for the audience to breed aesthetic fatigue and produce boredom. "

　　After the Korean drama "Touching the Heart" was broadcast in the middle period, it still repeated "sprinkling sugar", which has already made many viewers choose to abandon the drama. After the popularity of domestic sweet pet dramas, there have been many similar themes on the market in the past year, but there are not many works that can reach the same flow as "Sweet honey is as heavy as frost" or "Two-time pet princess". It is worth noting that many works are "sweet for the sake of sweetness" or fabricate high-sugar plots that violate the logic of life for the sake of "sweet pets", which have actually aroused the audience’s disgust. Su Zhan, an industry critic, said that in the past, the audience hated the story of sadism just because they hated the suspension of the giant fighting drama. Nowadays, the threshold of sweet pet drama is lower, and creators can take advantage of the wind to extend the "sweet abuse" indefinitely, but don’t push them to suspension and entertain themselves. Whether it is an emotional drama focusing on sweet pets or sadomasochism, only under the correct guidance of reality can it go on for a long time in the market.

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.

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)

　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.

　　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。

[Lead: New energy vehicles that are licensed after December 31, 2022 will no longer enjoy the purchase subsidy, and the "state subsidy" will become history, which makes a number of car companies face the pressure of price increase. The price increase of battery raw materials is another main reason for the price increase of new energy vehicles. This means that the new energy vehicle has officially opened the "head-on confrontation" mode with the fuel vehicle. 】

Author | Cai Jialun, Editor | Hezi

The price increase of new energy vehicles is imminent. Is it the foil of marketing strategy or the influence of dynamic changes of policies and markets? 2022 is coming to an end, and major car companies have also reached the stage of sprinting at the end of the year. The sales volume at the end of the year determines the development direction of the next year. According to the overall market sales this year, major new energy vehicle companies will inevitably have a fierce battle at the end of the year. Although the marketing strategy is a way to drive the purchase, this time it is not aimless. Because as early as the end of last year, the Ministry of Industry and Information Technology and other four departments have informed that the policy subsidies will end on the last day of this year.

"National compensation" will eventually become history.

In order to vigorously develop the new energy vehicle market, after discussion by relevant departments, since 2010, consumers who purchase new energy vehicles can enjoy state subsidies according to the types of vehicles they purchase. According to the relevant data of China Automobile Association, from January to October this year, the production of new energy vehicles in China reached 5.445 million units, an increase of 111% over the same period last year; Sales reached 5.28 million units, up 105% year-on-year. It can be seen that the development of new energy vehicles in China is quite outstanding, and both products and technologies have achieved a qualitative leap. "National compensation" plays a vital role in promoting the development of China’s new energy vehicle market.

With the continuous growth and maturity of the new energy vehicle market, the sales volume and ownership of new energy vehicles are also rising. At this time, the role of "subsidy" to promote the development of new energy vehicles will naturally not be as "important" as when the market just started. According to the current market situation, the relevant departments made timely adjustments and decided to cancel the subsidy policy for new energy vehicles: new energy vehicles that are licensed after December 31, 2022 will no longer enjoy the purchase subsidy, and the "state subsidy" will become history.

Subsidies have been cancelled, and manufacturers have "made moves"

With the withdrawal of the state subsidy policy, car companies have to face the cost "pressure" again. In order to ensure that their profits are not affected by a large area, many car companies have "made moves" to open their own marketing strategies. The first move is. A few days ago, the official issued a price adjustment statement, announcing the price increase of a variety of products including its Dynasty series and Ocean series, with the price increase ranging from 2,000 to 6,000 yuan. As the first car company in China to stop selling fuel vehicles, this is the third price increase this year. In the explanation, it is also clear that the reason for the price increase is directly related to the cancellation of subsidies.

It was Ian who announced the price increase. On November 30th, Ai ‘an released the explanation about the price adjustment of the vehicle models, which clearly stated that it would raise the price of its related models by 3,000 to 8,000 yuan. Similarly, consumers who pay the deposit before January 1, 2023 and complete the contract will not be affected by this price adjustment and continue to enjoy the relevant rights and interests. At the same time, many enterprises such as Wenjie, Tucki, etc. have also issued the statement of "National Supplementary Insurance Price" according to their own conditions. For example, in Tucki, as long as the order payment is completed on December 31st, they can enjoy subsidies, and even if the listing time is delayed, the corresponding difference will be borne by the enterprises.

Of course, not all car companies choose to raise prices in response to the withdrawal of the national subsidy policy. Not long ago, on the basis of the highest price reduction of more than 30,000 yuan, the official announced the second "price reduction". This price reduction will be given back to consumers in the form of subsidy insurance. If the car is picked up on time in November, the owner will enjoy an insurance subsidy of 8,000 yuan, while the corresponding subsidy will be halved for consumers who pick up the car in December. There is also a zero-run for price reduction promotion. For its hot-selling models, consumers can complete the deposit payment before December 4 and complete the licensing before December 31, and then they can get a cash back subsidy of up to 12,000 yuan.

Is it really the best time to buy new energy vehicles?

To put it bluntly, it is only a matter of time before the new energy car companies raise prices after the withdrawal of the state compensation. In recent years, the price of new energy vehicles has been unstable. Due to the epidemic, the cost of raw materials and the price of power batteries have soared. Many car companies once announced the suspension of production because of "lack of core". High costs and meager profits can be said to make major manufacturers miserable, and canceling the subsidy policy is tantamount to adding a "heavy burden" to enterprises. In order to protect their own interests, price increase is definitely the most effective and direct way. But for consumers, the "extra" increase in car purchases is undoubtedly a big loss.

Whether it is the best time to buy new energy vehicles now mainly depends on whether the new energy vehicles are actually bought. First of all, let’s look at the price. After the withdrawal from the market, the most serious impact will be the pure electric vehicles from 150,000 to 250,000. After all, in this price range, fuel vehicles still have strong competitiveness, and it is difficult to completely replace its "Jianghu status" in a short time; Secondly, most consumers who choose this price will pay more attention to the practicality of vehicles. The problem of charging energy and mileage anxiety of pure electric vehicles is also the main reason why they keep waiting and seeing. After the withdrawal of the state compensation, the product strength of new energy vehicles has once again ushered in a test.

Although the withdrawal of the state subsidy will have a certain impact on the new energy vehicle market, it will also "sound the alarm" for the new energy vehicle market. Cars really can’t be built by anyone. There are no "genuine" products that can be obtained, and no matter how good-looking PPT is, it is also a verbal check. Those "empty shell" companies that "fill in the blanks" and take policy subsidies will eventually be eliminated by the market.

comment

Without the blessing "protection" of the national subsidy policy, new energy vehicles finally ushered in a "positive confrontation" with fuel vehicles. This also urges car companies to increase investment in technology research and development, product upgrading and other aspects. With the delisting of the state, the new energy automobile industry will eventually usher in a transformation. Although the price is no longer "cheap", the more standardized market environment is undoubtedly a major benefit to consumers. After all, only excellent products can be invincible in the market. Some "weak" car companies will also fall in the "post-subsidy era".

Recently, The 12th International Conference on Learning Presentations (ICLR 2024), one of the top conferences in the field of international machine learning, announced the paper recruitment list. Professor Lu Baoliang from the Department of Computer Science and Engineering of School of Electronic Information and Electrical Engineering, Shanghai Jiaotong University, together with Shanghai Zero Unique Technology Co., Ltd., has been selected as the ICLR 2024 Spotlight paper "Large Brain Model for Learning Generic Representations with Tremendorus EEG Data in BCI". There are 7,262 papers submitted worldwide, with an overall acceptance rate of about 31%, of which 5% were selected as Spotlight papers.

Research background

At present, deep learning models based on electroencephalogram (EEG) signals are usually designed for specific data sets or brain-computer interface (BCI) application tasks, which limits the scale of the model and fails to give full play to the representation ability of EEG signals. Recently, Large Language Model (LLM) has made epoch-making progress in text processing. Under this background, Professor Lu Baoliang’s team started to study large-scale EEG model (LEM). Although they are in different fields, they have something in common in the task of data decoding. Researchers use the successful concept of text processing for reference to explore new methods for analyzing EEG signals and building brain-computer interface models, and expand the scientific research vision and application prospects in this field.

However, compared with text data, EEG data sets are usually very small in scale and different in format. The development of large-scale EEG models faces the following challenges:

1) Lack of sufficient EEG data

Compared with natural language and image data, it is extremely difficult to collect large-scale EEG data. In addition, the annotation of EEG data usually requires a lot of energy from domain experts, resulting in only a small number of labeled data sets can be used for specific tasks in BCI, and the EEG signals of these tasks are usually collected from a few subjects, and the duration is usually less than tens of hours. Therefore, there is not a large enough EEG data set to support the training of LEM.

2) Diversified configuration of 2)EEG signal acquisition.

Although there is an international 10-20 system to ensure the standardization of EEG signal acquisition, users can still choose to use EEG caps with different electrode numbers or patch electrodes to collect EEG data according to actual application needs. Therefore, how to process EEG data in different formats to match the input unit of neural Transformer is still a problem to be explored.

3) Lack of effective learning paradigm of EEG representation.

The low signal-to-noise ratio (SNR) of EEG data and different types of noise are very difficult problems. In addition, balancing temporal and spatial features is very important for effective EEG representation learning. Although there are various EEG representation learning paradigms based on deep learning (such as CNN, RNN and GNN) that can be used to process the original EEG data, many researchers still tend to design artificial EEG features because of the above problems.

research results

The goal of this paper is to design a general large-scale EEG model called LaBraM. The model can effectively process various EEG data with different channels and lengths. Through unsupervised training of a large number of EEG data, the research team envisages that the model will have universal EEG representation ability, so that it can quickly adapt to various downstream tasks of EEG. In order to train LaBraM, researchers collected more than 2,500 hours of EEG data of various tasks and formats from 20 public EEG data sets.

Firstly, the original EEG signal is divided into EEG signal channel segments to solve the problem of different electrodes and time lengths. Neural markers with rich semantics are trained by vector quantization neural spectrum prediction to generate neural vocabulary. Specifically, the marker is trained by predicting the Fourier spectrum of the original signal. During the pre-training, some EEG segments will be masked, and the goal of neural Transformer is to predict the masked marks from the visible segments. The research team pre-trained three models with different parameter sizes, 5.8 million, 46 million and 369 million, which is by far the largest model in BCI field. Subsequently, the research team fine-tuned them on four different types of downstream tasks, including classification and regression.

Fig. 1 overall architecture of lab ram. First, all the input EEG signals will be divided into EEG signal segments through a fixed-length time window, and then the time characteristics will be extracted by applying a time encoder to each segment. Then, temporal and spatial embedding is added to segment features to carry temporal and spatial information. Finally, the embedded sequence is transmitted to the Transformer encoder in fragment order to obtain the final output.

In this paper, neural Transformer is introduced, which is a general architecture for decoding EEG signals, and can process any input EEG signals with any number of channels and length of time, as shown in Figure 1. The key operation to achieve this goal is to divide EEG signals into blocks, which is inspired by fragment embedding in images. Because of the high resolution of EEG in time domain, it is very important to extract time features before segment interaction through self-attention. A time domain encoder composed of multiple time domain convolution blocks is used to encode each EEG segment into segments for embedding. Temporal convolution block consists of one-dimensional convolution layer, group normalization layer and GELU activation function. In order to make the model aware of the temporal and spatial information of fragment embedding, the researchers initialized a temporal embedding list and a spatial embedding list. For any fragment, the corresponding temporal embedding and spatial embedding are added to the fragment embedding. Finally, the embedded sequence will be directly input into the Transformer encoder.

This paper verifies the effectiveness of LaBraM on two downstream task datasets: TUAB and TUEV. We designed three different configurations of LaBraM: LaBraM-Base, LaBraM-Large and LaBraM-Huge. The parameters of LaBraM-Base are 5.8M, LaBraM-Large is 46M and LaBraM-Huge is 369M.

Tables 1 and 2 above list the best baseline results of TUAB and TUEV and the results of LaBraM. Obviously, LaBraM-Base model is superior to all baseline models in various evaluation indexes of these two tasks. Especially in the more challenging TUEV multi-class classification task, the model has achieved significant performance improvement. It is observed that with the increase of model parameters, LaBraM-Huge model performs best, followed by LaBraM-Large model, and finally LaBraM-Base model. The research team believes that this good performance is attributed to the increase of pre-training data and model parameters. The paper concludes that as long as there is enough EEG data, large-scale EEG models can learn more general EEG representations, thus improving the performance of EEG signals in various downstream tasks.

Figure 2 compares the performance of the model on TUAB and TUEV data sets, and whether it is included in the pre-training process.

In the pre-training process, the research team hopes that the model can learn the general EEG representation that is not specific to any specific task. Although tag data is not used in the pre-training, in order to eliminate the influence of pre-training data on downstream tasks, this paper compares whether the downstream task data set is included in the pre-training results. It is worth noting that the records of TUAB and TUEV do not intersect with the records of pre-training data sets. As shown in Figure 2, whether the downstream task data set is included in the pre-training process of the model has little influence on the performance of the model on downstream tasks. This shows that the model has the ability to learn general EEG representation, and provides guidance for collecting more EEG data in the future, that is, researchers do not need to spend a lot of energy labeling EEG data in the pre-training process.
