"Eliminate mixing! "When we put this PPT on Weibo, we actually expected that there would be great controversy.

picture

This PPT was issued at its own press conference this afternoon. The following fine print is actually today’s theme: ultra-fast charging+high battery life+self-operation, which will change the industry structure.

picture

Therefore, many people don’t understand why He Xiaopeng wants to mix DISS at the super-replenishment conference.

In fact, before formally introducing his own charging network, He Xiaopeng talked about his own logic, and in the subsequent small-scale group visit, he also responded to the key dispute about which is better: ultra-fast charging or power exchange.

picture

Next, let’s take a look at Tucki’s super energy. Let’s talk about whether it makes sense to "eliminate mixing".

Let’s start.

First, Tucki’s ultra-fast charging

What is Tucki’s super energy?

To put it simply, by 2025, Tucki will build another 2,000 ultra-fast charging stations, with more than 10,000.Pile filling, the maximum charging power is 480 KW.

picture

As for why you say "again"? At present, 1,000 self-operated charging stations have been built in Tucki, including 799 self-operated overcharge stations and 201 self-operated destination stations, covering all prefecture-level administrative regions and municipalities directly under the Central Government.

picture

As a reference, as of August 13th, 2022, there are 966 overcharge stations and 839 destination charging stations in China.

1、S4

At today’s Tucki Super Charging Conference, Tucki’s S4 Super Fast Charge made its debut. He Xiaopeng introduced that S4 super-fast pile filling has three advantages: lighter, smarter and safer.

picture

Lighter means that the cable weight of the charging gun is reduced by 36%, and the cable is significantly reduced.

S4, the smarter representative, supports plug-and-charge, touch-and-stop, and intelligent power distribution. According to the official, the startup speed will be controlled within 15 seconds.

Safer, it is the addition of liquid-cooled cooling charging technology, which can actively monitor the temperature rise in real time.

Tucki also laid out specific data and "hanged" a friend.

picture

The maximum power of S4 single pile is 480kW, that of V3 is 250kW, and that of Turbo is 350 kW;;

The maximum current of S4 single pile is 670A, that of Tesla V3 is 631A, and that of Porsche Turbo is 500A;;

The peak charging power of S4 is 400kW, that of Tesla V3 is 250kW and that of Porsche Turbo is 270 kW;.

Under CLTC working condition, the battery life of S4 is 200km, that of Tesla V3 is 150km and that of Porsche Turbo is 120 km after charging for 5 minutes.

In the field measurement, the cruising range of G9 with S4 ultra-fast pile filling was increased from 55 km to 265km after 5 minutes of charging, which actually increased the cruising range by 210 km.

picture

In the QA session after the conference, we asked how long the highest power of S4 can last. The official answer is that it can last for more than 6 minutes depending on the SOC status.

3. Ultra-fast charging layout

He Xiaopeng asserted today that the next era will be the era of ultra-fast charging.

But as he said, ultra-fast charging is a complete system, involving cars, piles and networks.

For example, power batteries, electric drives and high-voltage PTC should all support 800V high-voltage platforms.

From pile to network, it is a more important layout.

He Xiaopeng said that the goal in 2025 is to build another 2,000 ultra-fast charging stations and lay more than 10,000 piles, so as to realize "worry-free travel". At present, there are more than 1,000 stations, and some of them will be transformed into S4 ultra-fast charging stations.

picture

From the perspective of splitting, Tucki will start the construction of S4 Super Express Station in the third quarter of this year, first of all, it will be laid out in the top ten cities with G9 orders, including Beishang Guangshen, Chengdu, Chongqing, Wuhan, Hangzhou and other cities, and it will also deploy stations at high-speed entrances and exits in several important areas of China.

In 2023 and 2024, Tucki will focus on the deployment of high-speed and destination charging stations, aiming to build energy stations with a radius of 3 kilometers in key areas.

picture

Afterwards, we asked, how many S4 ultra-fast charging stations are planned in 10 cities this year? The answer is within 100 stops.

By the way, I need to add that at the end of 2022, Tucki will launch a brand-new charging map application. We feel that we are directly targeting the "power-on" App of Standard Weilai.

Second, eliminate mixing?

After talking about Tucki’s grand 480 KW super charging network plan, we return to the controversial sentence of "eliminating hybrid".

In fact, before talking about "eliminating mixing", He Xiaopeng made a lot of preparations.

For example, the "unexpected" surge of pure electricity,

He Xiaopeng said that around 2020, he had predicted that the proportion of pure electricity in China would reach 35% by 2025. But judging from this year’s situation, "all players in the industry have never seen such an amazing growth before." 」

22.7% new energy penetration rate!this isAccording to the data in the first half of this year, He Xiaopeng even predicted that in the second half of this year, it will reach 30% in a single month, and it will be above 25% in the whole second half!

This means that in the second half of this year, for every four cars sold in China market, one car will be a new energy vehicle!

It goes without saying that new energy vehicles must be the future!

However, pure electricity OR hybrid, who is the future?

picture

This is the first part that He Xiaopeng focused on after he took the stage today, and he used four or five PPT.

The reason for this is partly from logic. New energy vehicles are not only pure trams, but also hybrids.

But it is speculated that more comes from competition.

For example, the competition between G9, the medium and large-scale flagship of pure electricity to be listed in Tucki, and L9, the newly released extended-range flagship.

If it is enlarged to hybrid, it will at least include the super hybrid products supported by Huawei, such as M7 and M5, and even Great Wall, and so on.

Therefore, I feel vaguely that He Xiaopeng’s exposition is actually explaining why ultra-fast charging is "the winner of the next generation of smart cars". Why should Tucki add 2000 S4 and S3 ultra-fast charging stations and ten thousand ultra-fast piles by 2025? And the uniqueness of Tucki facing the future, or moat.

Third, the key logic

So, what is the key logic that He Xiaopeng thinks the future must belong to pure electricity?

The key three.

First, ultra-fast charging will bring about an explosion in the sales of pure electric vehicles with more than 200,000 yuan.

picture

He Xiaopeng believes that in the market below the price of 100,000 yuan, fuel vehicles are being rapidly replaced by pure electricity; In the market with the price of 100,000 to 20, at present, the performance of hybrid has been very prominent since last year. The key reason lies in economy. The price of this price is very sensitive, so the battery life will not be too high. The key is how to balance cost, battery life and convenience.

And "(pure electricity at this price) to solve this problem, it may take another two or three years, including the price of batteries, including the emergence of new technologies. 」

picture

In the market above 200,000, the growth rate of pure electric vehicles is relatively the fastest, and there is a new change in SUVs above 300,000.

Because people who buy large and medium-sized SUVs want to open in cities and suburbs, "poetry and distance are needed", which determines that large and medium-sized SUVs with new energy should solve not only the problem of endurance, but also the problem of mileage anxiety caused by recharging, and then have different solutions such as changing electricity, mixing and fast charging.

However, the current fast charging actually does not meet everyone’s demand for pure electric energy, and then Tucki decided to build ultra-fast charging models and networks to provide better experience services.

Starting from G9, all new or modified models behind (Tucki) will be equipped with ultra-fast charging as standard … basically, S3S4 is the core. ",and this means that Tucki’s energy replenishment will be two to three times faster than the fast charging network outside.

"In the past, we were able to charge the car from 10% to 80% in about an hour, and (later) from 10% to 80% in 20 to 30 minutes. 」

He Xiaopeng further indicated that the next generation of more than 200,000 mid-to-high-end and high-end electric vehicles will meet several special baselines.

The first is to have a long battery life.To achieve 700 km CLTC, it is equivalent to a real endurance of 500-550 (WTP conversion);The second is to charge quickly."I believe that cars with more than 200,000 vehicles must have ultra-fast charging. 」Finally, we mustDo a good job in charging layoutThe layout of cars, batteries and piles should be "three-in-one", and ultra-fast charging will become an entry requirement.

Second, pure electricity meets the needs of users in most scenarios, and the next car that plugs in users is often pure electricity.

picture

This is a very interesting judgment!

He Xiaopeng said that these judgments come from data analysis, for example, pure electricity has satisfied the vast majority of usage scenarios. He Xiaopeng said that most users in China drive less than 300km, and most of them charge once a week or 1.5 times a week.90% of the scenes are in cities and suburbs."There are more than 1000 km, but I think the proportion is less than 5%. 」

picture

And "in the past, many people asked a question, I use electricity in the urban area, is it more suitable to use oil in the suburbs?" "He Xiaopeng said, this is the logic of mixing. Recently, they saw a very good data-"After many people who bought hybrids got used to charging … once they found that they could charge, his next car idea was to buy a pure electric car with higher battery life. 」

Thus, brought hisThe third logic:Pure electricity is more practical than mixing!

How to apply the law? The explanation given by He Xiaopeng is that the electricity cost is lower; Driving experience, especially at high speed, is more comfortable and quiet; Even the average weekly charging times will drop from 2-3 times a week to less than or equal to 1 time.

The last explanation seems quite contradictory. But … now, as long as you charge at the charging station, you will probably agree with He Xiaopeng.

picture

He Xiaopeng said: When the battery life is higher, the charging efficiency is higher and the charging layout is better, the cost performance of pure electricity in the market of over 200,000 will be more prominent, and we are very confident that the ultra-fast charging, high battery life and self-operated charging stations will change the whole market structure. 」

I just don’t know if the ideal and asking car owners agree.

Five, fifteen questions

Question 1:Before that, the construction of the overcharging station in Tucki obviously slowed down. What are the reasons?

He Xiaopeng: The main reason is that in 2020, after thinking that ultra-fast charging is the future, we think that fast charging will basically be eliminated. The second reason, slowing down at high speed, is because it is found that many high-speed car owners expect a short waiting time for charging, which can only be met by ultra-fast charging. The third reason is that if you want to support all 800 V and silicon carbide in the car, you need to accumulate some technology.

Question 2: If we put all our energy into ultra-fast charging, it will have a great impact on the power grid, or have high requirements for the entire capacity and electricity facilities, and even build energy storage stations. Can it really be rolled out on a large scale in terms of cost?

He Xiaopeng: Ultra-fast charging can’t increase much (cost). My first is to judge the trend of technology, the second is whether it can be done, and the third is whether it is expensive or not, and whether the construction can continue. After judging all these points, I think the ultra-fast charging can be fully laid out in the second half of this year-it will be done well from the end of the third quarter of 2022, that is, next month.

Question 3: In what range is the unit price of S4?

He Xiaopeng: It is not convenient to disclose the price at present.

Question 4: Is there a specific site plan for S4 ultra-fast charging? How many piles are there in a site?

He Xiaopeng: Basically, there are four piles in one station; Medium-sized stations have eight piles. We will have some extra-large stations in the future, and some stations may have dozens of piles. It’s what we’ve always wanted to do, and it may be in a bigger city in the first line.

Question 5: Is it possible to lay out the layout in the high-speed service area?

He Xiaopeng: At present, we have seen a very gratifying change. The State Grid and China Southern Power Grid, including provincial highway administrations, are building high-speed fast charging piles, which may be 60kW, 90kW and 120kW. If the capacity is limited and the layout is capable, we will all cooperate with them. If not, it may use energy storage stations or layout at high speed. It is also convenient to lay piles at high speed. In fact, it is very convenient if it can be densely distributed at the high-speed port.

Question 6: What is the layout plan for 10 cities this year?

He Xiaopeng: There are not many piles this year, and the number of sites is probably within 100; Next year will focus on construction, the number will increase significantly.

Question 7: If there are 3,000 stations distributed all over the country in the future, how will Tucki maintain them?

He Xiaopeng: We have made some adjustments, putting the national after-sales team and the over-filled pile maintenance team together, and having a team of after-sales service system throughout the country. On this basis, through data management, if someone finds that the pile can’t be filled, they can tell us immediately, and we will remove the pile in the reservation system and then arrange maintenance.

Question 8: Some people say that the problem of infrastructure overcharge is left to the state, and it is a drop in the bucket for cars to do this. What do you think of this problem? Besides, what do you think of changing electricity?

He Xiaopeng: I don’t think this infrastructure should be considered if the vehicle is between 100,000 and 200,000 yuan. This is the scope that the more expensive and bigger the vehicle is, which is caused by different positioning. Secondly, I believe that the country’s infrastructure will be completed one day, which I believe very much, but at present, there are operational challenges, service problems and inconsistencies in various capabilities. Third, some people change power, some people mix, and some people take ultra-fast charging. There must be some solutions to the problem. I think there is no right or wrong, and they are all good solutions. However, we believe that such a scheme may be more suitable in the long term, from the perspective of globalization and energy security, and different schemes have different challenges in the short term.

Question 9: Will Xpeng Motors consider the mode of changing power stations in the future?

He Xiaopeng: We are now.Without considering changing electricity,The back is full of ultra-fast charging.

Question 10: Will the previous models consider iteration or upgrade? Will the previously deployed overcharge be adjusted?

He Xiaopeng: There are great differences between S4 ultra-fast charging and S2 fast charging systems, and they are basically new. The ultra-fast charging of S4 is compatible with the charging of S3 and S2, which is actually equivalent to improving the average charging efficiency of the original vehicle. However, from the perspective of the vehicle, it is difficult for the previous vehicle to upgrade from S2 to S4 because of the need for battery adjustment.G4 is supported by G9, S3 is supported by other configurations, and the actual requirements for batteries are different.

Question 11: Will S4 ultra-fast charging be open to third-party brands? Is it all backwards compatibility?

He Xiaopeng: We will be open in some places, but if our car owners have high demand, they will all enjoy it, because it is the most difficult to find electricity by themselves. As for compatibility, of course, all compatibility.

Question 12: What is the level of electricity charge and service price after S4 is super-fast charged?

He Xiaopeng: It’s the same at present.

Question 13: What is the battery decay life after using this high-power overcharge?

He Xiaopeng: Last year, we made a lot of efforts to customize batteries, and cooperated with battery companies to change the whole intelligence, the whole management, the power of the whole car, the module and the power module of the pile. This is the most concerned reason, so as to make everything unsafe and hands-free.

Question 14: Just now, we mentioned that there are about four piles in a station, all of which are 480kW power. If we want to run to full capacity, it means that there must be more than 160kW capacity. At present, the power grid is still difficult to support. How can Tucki solve this problem?

He Xiaopeng: At the same time, four cars are charging on this pile. I believe the probability will be lower. If you take one car for each pile, I can go at the highest speed. I may be different between two cars. Secondly, we just saw that 5 minutes is the fastest, followed by 10 minutes. After 20 minutes of charging, the speed will slow down. It is a charging curve. First, it will be charged quickly, and then gradually. When it reaches 90%, you will find it is very slow. It will charge slowly to ensure the safety of the battery. You will see that some cars may be at 70% of the time, and he doesn’t have to be so fast. He can give another car 10% or 30% of the charge, so there is no need to multiply the overall capacitance by 4.

Question 15: How much capacity does a single station generally need?

He Xiaopeng: That’s 480 kW.

(End)

A shares closed down in shock: the Shanghai Composite Index fell by 0.95%, while the Shanghai Composite Index fell by 1.47%.

The shock closed down, and the transaction between the two cities broke through one trillion yuan for five consecutive days.

The three major stock indexes of A shares opened lower collectively on March 22nd. In early trading, the two cities stepped out of the unilateral downward trend, and individual stocks showed a general decline. It picked up in the afternoon, and the decline of the three major stock indexes narrowed significantly.

From the disk, the indexes of CRO, lithium mine, battery recycling, gold, PEEK materials, photovoltaic, new energy vehicles and satellite navigation were adjusted back, while liquor, basic metals, insurance and agriculture were among the top losers. The cultural media sector is on the rise, and Kimi and high-speed copper connection are active.

By the close of March 22, the Shanghai Composite Index fell 0.95% to 3,048.03 points; The Science and Technology 50 Index fell 1.48% to 794.2 points; Shenzhen Component Index fell 1.21% to 9565.56 points; The growth enterprise market index fell 1.47% to 1869.17 points.

So far, this week, the Shanghai Composite Index fell 0.22%, the Kechuang 50 Index fell 1.79%, the Shenzhen Composite Index fell 0.49%, and the Growth Enterprise Market Index fell 0.79%.

Wind statistics show that 924 stocks in the two cities and the North Stock Exchange rose, 4,385 stocks fell, and 43 stocks were flat.

On March 22, the total turnover of Shanghai and Shenzhen stock markets was 1,097.3 billion yuan, an increase of 29.6 billion yuan compared with 1,067.7 billion yuan in the previous trading day, and it broke through one trillion yuan for five consecutive trading days. Among them, the Shanghai stock exchange traded 456.8 billion yuan, an increase of 19.2 billion yuan over the previous trading day of 437.6 billion yuan, and the Shenzhen stock exchange traded 640.5 billion yuan.

According to Great Wisdom VIP, 75 stocks in the two cities and the North Stock Exchange rose by more than 9%, and 18 stocks fell by more than 9%.

On March 22nd, northbound funds had a total net outflow of 3.138 billion yuan, and once reduced their positions by over 6 billion yuan in the afternoon. Among them, Shanghai Stock Connect sold 1.714 billion yuan and Shenzhen Stock Connect sold 1.424 billion yuan. This week, northbound funds accumulated a net sale of nearly 7.8 billion yuan.

Household appliances strengthened against the market, and insurance stocks fell sharply.

In terms of sectors, household appliances strengthened against the market, Fujia shares (603219) rose by over 4%, Changhong Meiling (000521), Biyi shares (603215) and Hisense Household Appliances (000921) rose by over 2%.

Coal stocks strengthened, while Jinkong Coal (601001), Shaanxi Coal (601225), Meijin Energy (000723) and mountain coal international (600546) rose.

Media stocks performed well, with Huace Film and Television (300133), Reader Culture (301025), Zhongyuan Media (000719), Zhongguang Natural Selection (603721) and Palm Reading Technology (603533) rising by more than 10%.

Non-ferrous metals were among the top losers, with Sheng Da Resources (000603), Zhongrun Resources (000506), Feinan Resources (301500) and Xianglu Tungsten Industry (002842) falling more than 4%.

Insurance stocks fell sharply, dragging down non-bank financial sectors, with China Ping An (601318), Rendong Holdings (002647), Xinli Finance (600318) and New China Life Insurance (601336) falling more than 2%.

The computer sector performed poorly, with Zhilai Technology (300771), Rice Information (688631), Desai Siwei (002920), Haofeng Technology (300419) and Chuanda Zhisheng (002253) falling more than 6%.

It is more likely that the subsequent market will enter the shock stage.

Guotai Junan said that the index is in a sideways shock stage, and it is recommended to pay attention to the theme concept sector. In the morning, the two markets opened lower and went lower. The Shanghai Composite Index once fell below the 20-day moving average, but there were only more than 20 stocks that fell more than 7%. There was no obvious panic. In the afternoon, AIGC themes such as media and data confirmation rose sharply, driving the index to stabilize. It is more likely that the follow-up market will enter the shock stage, mainly due to the lack of new impetus for the expected revision. The rebound of the superimposed market has accumulated a large increase, and the upward momentum of the index has weakened. However, from the mid-line point of view, the market microstructure is clear, and the reports of the two sessions clearly put forward "enhancing the internal stability of the capital market", and the bottom of the stock market has appeared. The market is expected to show an exponential shock and the theme concept plate is active.

On the theme, it is suggested to focus on new quality productivity and low-altitude economy/domestic computing power/emerging hydrogen energy. Decision-makers frequently mention "new quality productivity", and policies are expected to focus on the cultivation and development of new industries/new models/new kinetic energy, focusing on: 1) low-altitude economy: policies at all levels lead the acceleration of commercialization, and are optimistic about aircraft manufacturing/parts and flight service companies. 2)AI computing power: led by the "artificial intelligence+"action, the construction of domestic intelligent computing centers is expected to accelerate, and we are optimistic about the domestic optical interconnection/computing chip/Huawei intelligent computing industry chain. 3) Emerging hydrogen energy: industrial policies are intensively introduced, and the hydrogen production-storage and transportation-industrial hydrogen link is opened. We are optimistic about hydrogen production/storage and transportation equipment and fuel cells. 4) Domestic substitution.

Guosheng Securities said that since February, A-shares have experienced nearly one and a half months of repair, and the trading activity has gradually increased. In the case of foreign capital and "domestic capital" simultaneously adding A-shares, the market may have certain sustainability. Technically speaking, the selling pressure around 3090 points of the Shanghai Composite Index needs to be released, and the short-term defensive position is 3030 points. The upward breakthrough needs to continue to enlarge the trading volume, and it is not broken or a good opportunity to add positions. The active theme may continue to focus on new quality productivity, artificial intelligence, low-altitude economy, etc., and pay short-term attention to the main branches such as carbon fiber, AI+PC, consumer electronics and semiconductors. In operation, it is suggested to give priority to bargain-hunting layout and pay attention to high-low switching.

Founder Securities said that China’s cross-border e-commerce continues to be stable and positive, and it is expected to become a new foreign trade format with the fastest development and the greatest potential in the future. AI has rich application scenarios on the supply side of e-commerce (writing emails, optimizing Listing, after-sales service, etc.) and on the demand side (recommendation system, voice assistant, image search, etc.), and it is one of the core tracks for the commercialization of AI at present. At present, with the continuous iteration of AI technology, the continuous enrichment of subsequent related functions is expected to drive the penetration rate to continue to rise. Platform enterprises with AI service capabilities are also expected to form new differentiated advantages through product stickiness, further consolidate their market share and achieve industry leadership.

The female driver of the online ride-hailing car recorded 62 passengers in 4 months. The story is about to be published in a book (Photos)

Jiang Meixia organized the four passenger stories she recorded into a book and named it "Right Heart · Listening".

  Ms. Jiang took more than 200 rides for about four months and recorded the stories of 62 passengers, about 70,000 words. "Living in other people’s lives, truly feeling their joys and sorrows, switching between emotions, unable to help herself," she wrote at the end of the book. "Having such an experience is worth sobering up and satisfying."

  And behind her recording these stories is the mutual trust and tolerance between strangers.

  The 62 passengers covered all walks of life, of different ages and classes. Most of them started with the appearance of the passengers and the place where they got on the bus. Their stories could be described as strange.

  "No matter what everyone is going through, they are generally satisfied and have their own little happiness." Jiang Meixia said that she set the tone for herself from the beginning to record these "positive energy" things.

  Chengdu Business Daily reporter, Yu Zunsu, Lu Wangyi, photojournalist, Zhang Jian

  After 120 days of online hailing and carrying more than 200 strangers, Jiang Meixia recorded the content and experiences of her chats with passengers in 60,000 to 70,000 words, bound into a book and titled "Right Heart · Listening". Just like Pu Songling, who set up a stall for tea in exchange for stories, in just four months, Jiang Meixia used online hailing to "break" into the lives of strangers in this city, and exchanged them for ordinary and touching stories. At present, she is still revising these stories, "hoping to find a suitable publisher to publish these stories."

  Hundreds are harvested every day

  But not RMB, but text

  "When I experience my own joys and troubles, I think from time to time. Are others as happy as I am? Are others as worried as I am? What kind of life are they living?" – From Right Heart · Listening

  Due to the need to take care of her daughter in the third year of high school, Jiang Meixia has no online car-booking now. A bound "book" is kept at home, full of the experience of driving and soliciting customers. In her words, "I get hundreds of dollars every day, but unfortunately it is not RMB, but some scattered words."

  Even though she is already a mother, Jiang Meixia still maintains a curious heart about new things. Last year, she signed up for a ride-hailing account. "I just want to experience it, not to make money, not to meet strangers, just to learn about new ways of getting around." During the four months from May to August last year, Jiang Meixia drove her Toyota SUV and started driving online hailing in the main urban area of Chengdu.

  Once near Taikoo Li, a male passenger "collapsed" in the passenger seat as soon as he got on the bus. "I was really depressed." The way the other party talked made Jiang Meixia unable to adapt for a while. "I also chatted with him naturally, like real-world friends who have known each other for a long time." She said that the man told her that he was a special ride on the Internet to chat with strangers. "This should be one of the first 10 passengers I pulled, and it is also the first time I met a passenger not to go somewhere, but to chat." Jiang Meixia said that this is the first time in her life that she has acted as a confidant sister for a stranger.

  "In fact, every passenger has their own thoughts that are inconvenient to share with their family and friends." Since then, Jiang Meixia, who has always liked to code, has the idea of deliberately digging into the stories of strangers around her. "I want to treat myself as a driver and break into their lives." After that, there are more notebooks and pens in her car, and she will record the interesting stories one by one and organize them when she gets home.

  By August last year, Jiang Meixia had run an online taxi for about four months. She received a rough count of more than 200 orders and recorded the stories of 62 passengers, about 70,000 words.

  The trust and tolerance of strangers

  Four months of feeling like living someone else’s life

  "Baby, don’t worry, it’s been a long time! Just like that, enjoy it casually, happily, and carefree, and grow up slowly." – From "Right Heart · Listening"

  After graduating from college, Jiang Meixia worked in sales for many years. "To do sales is to ask for people. Although customers change from unfamiliar to familiar, they have interests, so it is difficult to have such a simple and easy chat." Before that, Jiang Meixia believed that there was no trust and deep communication between strangers. "I take a taxi and never talk to my master." However, the experience of driving an online car-hailing made her feel that strangers can also chat like this – like friends, talk about work and life.

  "When I experience my own happiness and troubles, I think from time to time, are other people happy like me? Do other people have the same worries as me? What kind of life are they living?" This is the passage at the beginning of Jiang Meixia’s book. In four months, her passengers include elderly people in their late 80s, babies waiting to be fed, junior high school students, newcomers in the workplace, sweet couples, successful people… Different people tell different stories.

  At the end of the book, Ms. Jiang writes, "Living in other people’s lives, truly feeling their joys, sorrows and sorrows, switching between various emotions, and not being able to do it yourself. Having such an experience is worthy of sobriety and satisfaction."

  She said that the little happiness expressed by strangers moved her, and she had met people who were full of complaints due to the pressure of life, but everyone was looking forward. Behind the recording of these stories is the mutual trust and tolerance between strangers.

  Zhang Lan, a psychology expert, said that common topics are the basis for chatting with each other, and the enclosed moving space of the carriage creates such a chatting environment for passengers and drivers. "Everyone has the need to share and talk, but you may not find someone willing to listen in life. There is no interest relationship between strangers, they are psychologically equal, and there is no cost from the beginning to the end of the communication."

  This also explains why so many strangers are willing to take the initiative to chat with Jiang Meixia, allowing the online ride-hailing driver, who majored in Chinese and worked in sales in college, to have the opportunity to record the stories of unfamiliar passengers.

  62 passengers from all walks of life

  "Everyone has their own little happiness"

  "Living in other people’s lives, really feeling their joys and sorrows, switching between various emotions, and not being able to do it yourself. Having such an experience is worthy of sobriety and satisfaction." – From "Right Heart · Listening"

  Looking at Jiang Meixia’s book that tells the stories of unfamiliar passengers, the 62 passengers cover all walks of life, of different ages and classes. Most of them start with their appearance and boarding location, and their stories can be described in various ways.

  In the book, a primary school student told her that the study pressure was too great, and she had to go to the training class to make up lessons during the holiday, and she had to play the piano after making up lessons. Once, a 73-year-old lady got on the car, and few elderly people would use the software to call a car. Jiang Meixia praised a few words, and the cheerful old man said that if she had not had diabetes for more than 20 years, she would be in better spirits. Thinking that her mother had just been diagnosed with diabetes, Jiang Meixia paid attention to ask more questions. The old man very enthusiastically advised Jiang Meixia not to worry, and also recommended to her the medicine he had been taking.

  In the account, Jiang Meixia once again mentioned a male passenger who had been picked up in Taikoo Li. The other party said that he had started from scratch to invest millions to open three tea restaurants in the city center, and he was sitting in several luxury cars. He seemed to be a successful person in the eyes of his relatives and friends. But others did not know how tired he was. He rolled his sleeves and washed dishes when he was busy in business, couldn’t even pay the chef’s salary when he was in bad business, and his wife was unwell. The huge mental pressure made him unable to breathe, but he couldn’t tell his employees and friends that he "always had to stretch".

  "You and I don’t know each other, and the chance of meeting again is too small, so I won’t drive today, thank you for being my audience." Arriving at the destination, the man said, feeling better after complaining, and thanked Jiang Meixia apologetically.

  "No matter what everyone is going through, they are generally satisfied and have their own little happiness." Jiang Meixia said that she set the tone for herself from the beginning to record these "positive energy" things.

  In fact, it is not easy to chat with unfamiliar passengers every time. Jiang Meixia does not shy away from this point. She said that in fact, there are also some passengers who are very negative. She also recorded such passengers in her book: She once picked up a lady in Shiyangchang. After getting on the bus, the other party began to complain about her family and business. "Alas, business is too difficult now. The noodle shop became annoyed and couldn’t find a way to live in the clothing factory the day before yesterday. It’s so hard to make money!"

  She said that she tried her best to keep the passenger from being so depressed, but she seemed a little powerless. "Sometimes, people are infected by this negative emotion." But later, she thought that the passenger might feel better after complaining.

  Last September, because her daughter was in high school, Jiang Meixia stopped driving online taxis, and she began to organize the 62 passenger stories she had written down. She named the story and mood told by the passenger sitting on her right "Right Heart · Listening". In addition to the preface and postscript, the first chapter "Listening to the Wind" tells the little happiness of ordinary people, the second chapter "Slow and Long" records the cuteness and troubles from elementary school students to college students, and the third chapter "Practice" is the richest. It contains 32 stories, all of which are the mental journey of passengers in the workplace or with rich social experience.

  For now, she is still revising the stories, "hoping to find the right publisher to publish them."

  The passengers recorded by Jiang Meixia

  ● Hit the "flying" Lairong to eat the fly restaurant

  Received a call from Beijing. As soon as they got on the bus, two passengers, a man and a woman, discussed the twice-cooked pork and cold white meat for lunch, and smacked their tongues. "Are you here for business?" The female passenger rushed to answer: "We are here specifically for Chengdu cuisine. We don’t go to a single scenic spot, we find a place to eat every day, then go shopping, then eat again, go shopping and eat, hahahaha." The two who jokingly called the tour "foodie journey" laughed.

  I suggested that the two refer to the rankings of Dianping, but the male passenger said that he did not want to go to the big-name restaurants that are blooming everywhere, and he chose the small restaurants that the locals like to go to. The taste is authentic.

  ● Bad luck

  I made an appointment to pick him up at the entrance of Fuqin Community, and I saw a man in a gray jacket standing handsomely in the middle of the isolation pile, holding a small floral umbrella in one hand, looking at his mobile phone, and then looking at the direction of my car. Parking close to him, he quickly folded the umbrella, carefully placed the umbrella next to his right foot, and turned to me: "Go to He’s Orthopedic Hospital."

  "Oh, it’s raining too much, I can’t go out at all." The man looked at the continuous rain outside the window and sighed.

  "A few days ago, the newspaper also reported that an uncle sent two children to school and was washed into the river and disappeared. It’s terrible." The attentive man turned his head and said, "Drive slowly on rainy days.

  "Well, you can see little scrapers everywhere on the road these days." I smiled gratefully at him, "So don’t think I’m driving slowly."

  "How could it be? I am a person who has suffered a loss, and I will definitely not be too slow." The man saw my doubtful expression and patted his right arm wrapped in a jacket, "I am going to the orthopedic hospital to change my medicine. I got off work a little late one day last month. Because I live in Wenjiang, I wanted to go home quickly. I rode a battery car on the express lane at a speed of about 65 yards, but I was hung up by the taxi and broke my shoulder blade. Fortunately, the reflector of the taxi hung me down. If the car hit me directly, the consequences would be unimaginable."

  "However," the man changed the topic, "Thank God for giving me such a profound experience when I was young. At least, in the next few decades, I won’t have any accidents because of my’fast ‘. The so-called disaster and fortune depend on each other, I’m really grateful."

  ● Sales

  Driving in the direction of home, I received a list.

  A man and a woman got into the car with raindrops all over their faces, and the boy also opened the door of the car to let the girl get into the car first. After getting into the car, the two continued to talk enthusiastically. The girl’s tone was obviously dominant and dominant, and the boy seriously echoed

  Suddenly, I felt the girl lying on my driving chair, a little uncontrollable excitement: "Sister, how much is your car insurance? Did you buy it?"

  "The car insurance must have been bought long ago, and it hasn’t expired yet." I thought to myself, "Are you afraid that if I don’t buy insurance, I won’t be covered if there is a problem on the road?"

  "Sister, your drivers should have a group, right? You usually communicate there? Our company has an event where we can give you as much red wine as you buy insurance. For example, if you buy insurance for 5,000 yuan, our company will give you 5,000 yuan worth of red wine, which is very cost-effective."

  "Really? There’s such a good thing? Then how do you make money? You always have to make money, right?" To be honest, I was a little on guard.

  "Look, I just said, you have to ask how you make money." The boy saw the stitches and teased a little. Feeling that the girl rolled her eyes at the boy, the boy immediately became silent.

  "During the current promotion period, we mainly want to promote the brand of our red wine. When the popularity is established, we will naturally make money."

  "Sister, do you have a lot of WeChat? I’ll add your WeChat, and I’ll send you the information about the red wine."

  I haven’t had time to answer yet.

  "Sister, this is my business card. If the introducer comes over, call me and promise to give you a commission." The girl’s tone was unquestionable.

  (Due to layout reasons, it has been slightly deleted.)

Samsung admitted that the previous adjustment was wrong, and the Galaxy Note 20 series and S20 FE mobile phone updates are still monthly.

IT House reported on April 5 that Samsung Electronics recently adjusted its product update push plan to reduce the frequency of security updates for Galaxy S20 and Galaxy Note 20 series mobile phones, from monthly to quarterly (once every three months).

Galaxy S20, Galaxy S20+ and Galaxy S20 Ultra have been on the market for four years, so it is understandable to reduce the push frequency of security updates.

but Galaxy Note 20, Galaxy Note 20 Ultra and Galaxy S20 FE were released six months later than the above three models.Therefore, adjusting the push frequency has made many users feel puzzled and dissatisfied. The revised updated equipment list is attached to IT House as follows:

Samsung then updated its product page, saying it was a mistake.The update frequency of the above four models will continue to maintain the monthly rhythm and will get the security update in April.

Mistaking bald heads for football AI’s poor eyesight is not only due to less training.

  Ai growing pains

  Editor’s note In recent years, artificial intelligence has developed rapidly and its application fields have been expanding. However, at the same time, AI "rollover" cases are frequently searched. Based on this, this edition opens the column "AI Growing Pains" to focus on AI "rollover" events, analyze the phenomenon, analyze the reasons, explore the solutions, and look forward to its growth.

  Intern reporter Dai Xiaopei

  After the game, it is probably unprecedented for fans to ask referees to wear hats or wigs.

  At the end of October, Scottish fans experienced an "unforgettable" football match. In the Scottish Football Champions League match between Furness and Elven, the AI cameras on the sidelines turned a blind eye to whether the players passed the ball or attacked with the ball. Instead, they followed a linesman and took a close-up of "C position" from time to time. It turned out that the AI camera mistakenly identified the referee’s bald head as a football, so he chased the whole game crazily.

  Fans who watched the 90-minute game at home spent most of their time not watching the ball, but watching the bald heads. Many netizens joked that this game really "saw a loneliness".

  Why does the AI camera regard the bald head as a football? What do we need to do to prevent AI from making similar mistakes? Can you think that AI is "weak" when there is a "rollover" incident?

  Unconscious "provocation" from bald referees

  From direct participation in sports events to recording athletes’ performance, to live broadcast of competitions and analysis of athletes’ health status, AI is becoming the darling of the sports world. A few months ago, Barcelona Football Club (Barcelona) also joined hands with video technology company Pixellot to create an artificial intelligence coaching solution.

  Unexpectedly, AI, which has made great strides in sports, unexpectedly encountered an unconscious "provocation" from a bald linesman. Because the linesman’s bald head is too bright and the sun shines, the AI camera can’t tell which is the ball and which is the head. Previously, because the Furness team said that the AI tracking technology they used could clearly transmit the live images to the homes of every season ticket buyer, so that fans who could not go to the home due to the COVID-19 epidemic would not miss any game.

  It is reported that the camera used in the live broadcast of this competition is the multi-camera system provided by Pixellot, which cooperates with Barcelona. The system is powered by NVIDIA’s graphics processor (NVIDIA GPU), and the captured video resolution can reach 8K. These cameras can be installed in a fixed position without being manipulated by the camera operator. In order to capture the key moments, Pixellot collected hundreds of thousands of hours of sports videos to train its algorithm on the NVIDIA GPU of the local workstation.

  With a huge amount of available data, using deep learning algorithms and high-performance GPU computing blessing, it has three major driving forces to push AI forward. Why did Pixellot’s AI camera "roll over"?

  After the event, the relevant clubs and the technology companies that make cameras reflected. The problem seems very clear: the size and shape of football are similar to those of a human head, and the direct sunlight makes the AI camera fall into "confusion". I hope this will not happen again, because the Furness team responded that it knew the problem and will improve the next game to bring a better experience to the audience.

  Pixellot also said that it is not difficult to solve this problem. The existing target detection and tracking technology is mature. Pixellot didn’t consider the influence of bald head in the design stage, so it needs to collect some data of football and bald head to fine-tune the algorithm to eliminate the interference from bald head.

  Some technicians said that not only "this is a ball" data set, but also a "this is not a ball" data set is needed when training the AI camera of the live ball game. Bald head, bright white shoes, lighting, balls on the training ground next to the competition field and balls used by players to warm up are all interference factors that need to be considered when training AI.

  AI "poor eyesight" is the norm.

  Although the performance of AI cameras can be improved by increasing data "feeding", strengthening training and improving algorithms, some professionals believe that with the gradual expansion of AI application scenarios, such "rollover" incidents will exist for a long time.

  “AI‘ Rollover ’ It’s normal, no ‘ Rollover ’ It’s strange. " Professor eecs and Huang Tiejun, president of Beijing Zhiyuan Artificial Intelligence Research Institute, spoke frankly when interviewed by Science and Technology Daily reporter.

  Huang Tiejun believes that on the surface, the failure of the AI ? ? camera may be due to insufficient pre-training, but the main reason is that the current computer identification system is only trained with specific data. For example, in the above example, the neural network trained with a large number of football videos has surpassed humans in identifying football, but it ignores that this network is more sensitive to bald heads.

  It is common to recognize or "turn a blind eye" unknown objects at random.

  Machine vision is to endow the machine with visual perception, so that the machine has the scene perception ability similar to that of biological vision system, which involves optical imaging, image processing, analysis and recognition, execution and other components.

  "Take the camera as AI ‘ Eyes ’ In real scenes, there is still a long way to go for AI to recognize football and baldness like human eyes. " Huang Tiejun said.

  When can I finish this road and even realize that the eye of AI surpasses the human eye?

  It depends on when machine vision will bridge the gap with biological vision. "The brain in the skull senses the outside world in real time through more than 3 million nerve fibers, of which there are more than 1 million behind each eye." Huang Tiejun said, "The machine vision developed to this day is still a drop in the bucket compared with the biological vision system that took hundreds of millions of years to evolve."

  The human eye has strong adaptability, can identify targets in complex and changing environments, has advanced intelligence, and can use logical analysis and reasoning ability to identify changing targets and summarize laws. On the other hand, machine vision can use artificial intelligence neural network technology, but it can’t identify the changing target well. Due to the constraints of hardware conditions, the current general image acquisition system has poor color resolution.

  "Compared with biological visual neural networks, the visual neural networks of artificial intelligence are far apart in structure and scale, so their functions are much worse." Huang Tiejun said, "In real applications, machine vision ‘ Rollover ’ It is not an accident. It is only a case to identify the bald head as a football. Similar problems actually exist in large numbers. "

  Huang Tiejun said: "This time, the technology provider can make up for the loophole that the bald head mistakenly thinks of football, but there are still more loopholes. Deceiving the face recognition system with antagonistic picture training is only the tip of the iceberg."

  Different technical routes are racing.

  "Machine vision based on deep learning has made great progress in image recognition, but it has not really solved the perception problem." Huang Tiejun believes that deep learning is far from grasping the complexity of human visual system.

  Deep learning is based on the training of image and video big data, which is far from the biological vision that actively perceives the dynamic world, and it is still not out of demand for computing power. For example, if the video frame rate is increased from 30 to 30,000, the computing power of deep learning needs to be increased by 1,000 times.

  Biological neural network is a pulse neural network, which is more suitable for completing visual information processing. Huang Tiejun believes that learning from the neural network structure and information processing mechanism of biological vision system and establishing a new set of brain-like vision information processing theory and technology is the hope of restarting machine vision.

  Experts said that there are two main technical routes to develop artificial machine vision. One is to build a powerful intelligent system by collecting more data, increasing the amount of data and strengthening training; The second is to imitate the biological nervous system, follow the gourd painting gourd ladle, clarify the structure and even mechanism of the biological nervous system, and develop future intelligence on this basis.

  Huang Tiejun believes that the second path is more effective than the first one. "In a short time, the first one is easier to achieve results. But in the long run, it is more direct to start with biological neural networks and more confident to achieve the goal. "

  At present, most AI scholars support the first path, that is, to develop artificial intelligence including machine vision through "big data+big computing power". Huang Tiejun set foot on the road taken by a few people because he firmly believed that the biological visual neural network had great potential to be tapped. "Biological brain is the product of hundreds of millions of years of evolution, and it is the best transcendental structure. Powerful intelligence must rely on complex structures and stand on the shoulders of evolution. It seems difficult, but it is the fastest. "

  Turing, the "father of computer science", has long expressed his admiration for the biological brain. At the beginning of 1943, Shannon suggested that "cultural things" could be instilled in the electronic brain. Turing once retorted in public: "No, I’m not interested in building a powerful brain. What I want is just an ordinary brain, just like the head of the chairman of AT&T."

  Is developing machine vision, or artificial intelligence, starting from scratch, imitating biological neural networks, or is there another way? There is no conclusion yet. On different tracks, artificial intelligence is accelerating.

  Although there are many cases of AI "rollover", such as the practicability of Google AI eye disease diagnosis system is greatly reduced in Thailand, Tencent AI translation made a joke at the Boao Forum in 2018. But the AI era is accelerating and unstoppable.

  "It must be admitted that AI has indeed solved many practical problems, and it will gradually replace some functions of people. But we can’t exaggerate it too much. It is still far from our imaginary intelligence and needs more breakthroughs. " Huang Tiejun said that to keep an open mind and bridge the gap between "experimental simulation" and "real world", the development of AI technology has a long way to go.

How did the National Open University exam come?

The undergraduate course of National Open University is recognized by the state. The undergraduate course of the National Open University is the undergraduate course of the Open University, including the undergraduate course of the National Open University and the undergraduate course of the open universities in various provinces and regions. It is an open education and a series of national education. So how did the National Open University exam come? If you have any doubts about this aspect of the National Open University, you can take a look at it with Xiaobian.

1. Written test

Some courses in the Open University may arrange traditional written tests, and candidates need to take the tests at the designated time and place, and complete multiple-choice questions, fill-in-the-blank questions and short-answer questions on the test paper.

2. Online examination

With the development of technology, more and more open universities switch their examination methods to online examination.

  CCTV News:According to the website of the Central Meteorological Observatory, the Central Meteorological Observatory issued a yellow typhoon warning at 10: 00 on July 26:

  This year’s No.6 typhoon "Fireworks" weakened to a strong tropical storm level in the west of Hangzhou Bay at 9: 00 am today (26th), and its center landed again at 9: 50 am along the coast of pinghu city, Zhejiang Province.

At 10 o’clock in the morning, its center is located in Pinghu, Zhejiang, which is 30.7 degrees north latitude and 121.1 degrees east longitude. The maximum wind force is 10 (28 m/s), and the lowest pressure in the center is 978 hectopascals.

  It is estimated that "fireworks" will move to the northwest at a speed of about 10 kilometers per hour, and its intensity will gradually weaken. It will move into Jiangsu at night today, turn to the northeast on the 28th and move into the Yellow Sea on the 30th.

  Defense guide:

  1. The government and relevant departments shall, in accordance with their duties, do a good job in typhoon prevention and emergency rescue.

  2. Water operations and passing ships in relevant waters should return to Hong Kong to take shelter from the wind, strengthen port facilities, and prevent ships from anchoring, grounding and collision.

  3. Stop large-scale indoor and outdoor gatherings and dangerous outdoor operations such as high altitude.

  4. Reinforce or dismantle structures that are easy to be blown by the wind. Personnel should not go out at will. They should stay in windproof and safe places as far as possible, so as to ensure that the elderly and children stay in the safest place at home, and the dangerous people will be transferred in time. When the typhoon center passes by, the wind will decrease or stay still for a period of time. Remember that the strong wind will suddenly blow, and you should continue to stay in a safe place to avoid the wind, and the dangerous people will be transferred in time.

  5. Relevant areas should pay attention to prevent flash floods and geological disasters that may be caused by heavy precipitation.
