On November 15th, the national launch of the third generation power station of Easy Connect was held in Hangzhou, marking another solid and important step for Easy Connect in the field of automobile power exchange. The third-generation power station of Yiyi Interconnection has made greater breakthroughs in the aspects of "power exchange speed, power exchange reliability and power exchange safety guarantee", which also indicates that the operating market is welcoming the "power exchange outlet".

   The power exchange mode is a "potential stock", which will effectively complement the charging mode.

    As one of the important ways to replenish energy for new energy vehicles, the power exchange mode has always been an important direction to promote new energy infrastructure construction. In October, 2021, the Notice on Launching the Pilot Work of the New Energy Vehicle Switching Mode decided to launch the pilot work of the new energy vehicle switching mode application. There are 11 cities included in the pilot scope, including 8 comprehensive application cities (Beijing, Nanjing, Wuhan, Sanya, Chongqing, Changchun, Hefei and Jinan). In July 2023, "Several Measures on Promoting Automobile Consumption" proposed to speed up the popularization, application and construction of the power exchange mode.

    Although the current mainstream market for new energy vehicles is charging, according to market research and analysis of relevant experts, the mode of replacing electricity also has huge market potential and industrial expansion space.

    In the future, changing electricity will inevitably become one of the most important ways to replenish energy in the new energy vehicle market, and it is a "potential stock" for industrial upgrading, which will effectively complement the charging mode.

    "Easy Connect Technology Co., Ltd.", a subsidiary of Geely Automobile Group, is a firm practitioner and active promoter of automobile power exchange mode. In January 2017, the R&D team of power exchange technology was set up; In September 2020, the Chongqing Exhibition Station was completed, and the power exchange mode was released for the first time; In January 2021, he won the "Golden Intelligence Award of the Year" in the third China Automobile Golden Coconut Award; In September 2021, as a new power for power exchange, it appeared at the Beijing New Energy Automobile Industry Development Achievement Exhibition; In October, 2023, the brand vision was released: to build the first brand in the operation market.

   Create the industry’s first smart electricity exchange ecological platform and become a "strength school" for big travel.

    Easy Internet has been deeply involved in the power exchange industry for more than 6 years, and has accumulated leading industry experience. It has more than 1,000 R&D personnel and invested more than 1 billion yuan. It has thousands of technical patents in the power exchange fields such as "power exchange architecture, power exchange station, standardized battery pack, power exchange vehicle, and station control cloud platform", and has issued more than 30 related standards for power exchange, and its reliability verification test has exceeded 300,000 kilometers, making it the first in the industry to have "complete vehicle-battery".

    According to Yang Quankai, president of Yiyi Internet Technology Co., Ltd., Yiyi Internet’s third-generation power station has the advantages of "high modularity, high compatibility, high intelligence, high service capacity and high security", reshaping the new experience of replacing electricity and replenishing energy.

    (1) High modularity: The power station adopts a highly integrated modular design concept, which can increase or decrease the number of boxes according to the service capacity, realize rapid disassembly, strong reproducibility and rapid deployment, and can stop at the station within 24 hours at the earliest. The single station of the power exchange station covers an area of 120-200m2, with small floor space and high efficiency ratio.

    (2) High compatibility: the unique open power exchange platform architecture can achieve multi-vehicle compatibility and achieve wheelbase bandwidth coverage of 2700-3100mm. It has opened customized service for vehicles to the market, promoting the coordinated development of technology and the promotion of power exchange technical standards. The adaptive ambient temperature range of the power station is-30 ~ 55 C, which can adapt to the low temperature weather in most northern winters.

    (3) High intelligence: the intelligent temperature control system under all-weather conditions has the characteristics of constant temperature and slow charging, dynamic inspection, etc., which ensures the intelligent control of the whole charging environment, realizes the interconnection of vehicles, stations and cloud platforms, and realizes integrated operation.

    (4) High safety: The power exchange station has a three-level fire protection system, and 24-hour cloud monitoring is implemented for the power exchange battery by using 5G technology, and the battery life is prolonged by constant temperature and slow charging. Seven-layer safety measures are adopted to ensure the safety of the battery and the power exchange station, and advanced locking mechanism design has established a safety barrier in the whole process of power exchange.

    (5) High service capability: With the intelligent power exchange management system, the automatic power exchange operation can be unmanned, and the whole process takes less than 1.5 minutes (the mechanical power exchange part can be completed in 40 seconds at the earliest), and the number of power exchanges in a single station is ≥540 times a day, saving 1-2 hours for drivers in each shift. The annual power exchange capacity of a single station can reach 7 million kWh, and the annual revenue of a single station can reach 10 million yuan.

    In the next three years, Yiyi Interconnect will operate 2,000 power exchange stations nationwide, and unite the efforts of all parties to provide high-quality power exchange and energy replenishment services for drivers, making power exchange faster than refueling; At the same time, E-easy Internet will also launch power exchange and energy replenishment solutions that specifically match the operating market, and build the first brand of power exchange and energy replenishment in the operating market. Up to now, Yiyi Interconnect has deployed and operated over 300 power stations in more than 30 cities including Chongqing, Hangzhou, Guangzhou, Chengdu, Tianjin, Jinan, Xi ‘an and Shenyang. The number of power changes per day exceeds 20,000 times, and the power change per day exceeds 600,000 kWh, and the operating data is growing steadily.

    At present, there are "Cao Cao 60, Maple Leaf 80v, Maple Leaf 60s, Ruilan 9, Ruilan 7, British TX5" which can be used for power exchange in the power exchange station of Easy Connect. More automobile brands are developing power exchange models and joining the power exchange system of Easy Connect one after another.

    Change the electricity to the windward port, and the break is in the present. As an important part of the new energy vehicle industry, the development of power exchange mode is of great significance to promote the popularization and application of new energy vehicles. With its long-term accumulation of outstanding technical strength and strategic layout of the operating market, Easy Internet is bound to lead the industry trend and help the industry upgrade.

　　The idolize fever in middle age tends to be more turbulent.

　　Writing/Starry Night

　　Editor/Li Xuanqi

　　Accompanied by a deep and crisp "rush" from Big Brother Huang Niu, Zhang Qinglan followed a group of young people around the age of 20 and rushed into the studio behind the black curtain.

　　Zhang Qinglan, 42, met a scalper selling fake tickets on her first trip to idolize and offline activities. After a thrilling experience, she rediscovered what idolize was.

　　From "Fake Jin Dong" defrauding "Aunt" of her true feelings with inferior videos, to the fact that in recent years, more and more middle-aged people have joined the idolize team, and middle-aged people with more abundant financial resources and more mature ideas are using their own ways to create a different kind of spark in generate in the wave of idolize.

　　Zhang Qinglan is a newcomer in middle-aged idolize, and there are many middle-aged fans like her. Being cheated by scalpers, unable to play online, unable to find organizations and other reasons have caused them to look like outsiders. However, there are still more "Zhang Qingyi" who have become fans of love beans, and they have the latest and most comprehensive love bean trends in their hands, so it is easy to call on a group of fans to support love beans together.

　　But the same thing is, the idolize fever of middle-aged people often comes more turbulent.

　　Standing outside the rice circle, I experienced an embarrassment of spending money on fake tickets.

　　Zhang Qinglan, who drove for two hours to the outside of the performance venue, looked at her young sister with a fan, a handkerchief, a light sign and other AIDS in her hand, and some make a fool of oneself in her heart: If you don’t have any equipment, will it seem very careless?

　　But in contrast, buying tickets is the most urgent thing at the moment. Because she is not good at playing Weibo Chaohua, Zhang Qinglan always knows the journey of Aidou a step later. By the time she realized that Aidou was coming to her city, the opportunity to get tickets had already passed.

　　More than two years ago, Zhang Qinglan got to know Jackson Wang from a child’s mouth, and then she became a loyal fan. "In the past, life always revolved around the family, and I didn’t know much about the entertainment circle, but after knowing Jackson Wang, I felt that he was really a valuable boy." Since then, Zhang Qinglan has played Jackson Wang’s songs in her headphones and watched Jackson Wang’s programs, and she has become a real fan.

　　After more than two years of silent pursuit, Zhang Qinglan finally got the chance to meet Jackson Wang for the first time. Not knowing the form of ticket sales and the arrangement of the support club, Zhang Qinglan just dressed herself younger and went to the scene alone.

　　After arriving at the meeting place, a middle-aged man wearing a black T-shirt, black trousers and black sneakers went straight to Zhang Qinglan, and then whispered back to her: "Do you need a ticket?" Zhang Qinglan, who was wondering that she couldn’t find the ticket booth, concluded at a glance that this was a professional scalper, so she thought, "It’s such a rare opportunity. As long as you can enter the stadium, you can buy a scalper ticket." “

　　Shortly after Zhang Qinglan arrived at the scene, the scalper took the initiative to strike up a conversation.

　　After a few simple inquiries, the scalper said that he had a channel for the staff to bring Zhang Qinglan into the venue disguised as a staff member, and only needed 800 yuan. However, it’s just to bring in the show. The scalper will give him a work permit that is not his own, and there will be no seats after the show. It depends on the individual.

　　In a short time, there were more people standing beside Zhang Qinglan, including two college students’ sisters, and boys wearing several clothes of Jackson Wang design brand "TEAM WANG" from head to toe. Zhang Qinglan learned through conversation that these brothers and sisters bought scalper tickets from idle fish, Weibo and other channels and then went offline to find someone.

　　After waiting for about ten minutes, the scalper in charge of selling tickets found two other helpers, dressed in the same clothes, with the same dark skin and the same accent. There is no doubt that they are a group of scalpers fighting in teams. One of the scalpers carefully looked at the gathered fans, including Zhang Qinglan, and said, "Two young, one old and one male, wait for me to find a similar work card."

　　At this time, Zhang Qinglan and several other fans still think that they can really get a work permit, but they just need to use it carefully. However, the situation changed quickly. The scalper who claimed to be looking for a work permit just inquired about the surrounding situation and suddenly came back and said in a low voice, "Come with me quickly and go in now."

　　At 17: 29, according to the ticket gate, there is still one minute left, but there are still two hours before the event begins. Zhang Qinglan followed the big troops around a railing and trotted to the side door of the performance venue. On the way, two staff members saw the chaotic scene from a height, and they stopped it aloud, but everyone had only one idea in the chaos — — Run hard.

　　At 17: 32, Zhang Qinglan was shocked by the scene when he arrived at the side door. About 30 young faces crowded together, and three or five scalpers began to complain. "How did you bring so many people?" It will be discovered if it is too eye-catching later. At that time, Zhang Qinglan and several fans in the same trade realized that it was a pure scam to enter the stadium with a work permit. The scalper just found an unguarded entrance and stuffed them into the stadium, and everything would be fine.

　　Before Zhang Qinglan and his friends recovered, the black curtain of the side door was suddenly opened by a staff member in the venue. At the moment, more than 30 people rushed in, and Zhang Qinglan, who was caught in the middle, had been wrapped into the field before he could react.

　　At 17: 38, about 30 people poured into the venue and scattered, each looking for a place to hide at will. However, Zhang Qinglan and several of his peers have begun to get anxious. One of the boys keeps looking for scalpers to talk on WeChat, while the other side continues to look for regular tickets that can provide places on idle fish.

　　In the face of doubts, the scalper quietly sent a message to Zhang Qinglan, "hide when checking tickets, or hide in the toilet first, and then find a fan with tickets to ask for an electronic code." Before everything was ready, the staff took the photos and looked for them one by one.

　　When the staff came to Zhang Qinglan and asked her to show her the tickets, she suddenly panicked and told the staff that she had been cheated by the scalper. When she arrived at the door, she realized that what she bought was not the tickets at all, but the opportunity to evade the tickets. After that, the staff seriously educated Zhang Qinglan and drove her out of the venue.

　　"That feeling is really shameful. I can’t be cheated by fake scalpers next time." After leaving the venue, Zhang Qinglan added several young fans’ WeChat, asking them to take her to find formal channels and grab tickets together next time.

　　In less than half an hour, Zhang Qinglan experienced embarrassment, panic and helplessness that may be difficult to meet at this age. On the way home, she saw the scalper who had just cheated her and took a new group of people to another path … …

　　Middle-aged people who are integrated into rice circles: buying endorsements and organizing activities to become big coffee in the circle.

　　Zhang Qinglan, who encountered an embarrassing and crazy scene in the initial attempt of offline activities, had extremely limited information because she stood outside the rice circle. But in fact, not all rice circles are led by young people, and many middle-aged people with strength and ideas are even more likely to stand in high positions.

　　In the seventh season of "Qi Pa Shuo", there is a debate topic: "Should I stop my mother from supporting male stars crazily?" Among them, the deer, as the debater of the opposing side, once broke the golden sentence: Why can’t there be a mother in the candlelight?

　　Zou Ying is such a mother in a light sign. She has never been to idolize before, but now she is an avid middle-aged groupie in the eyes of her family.

　　"Zhu Yilong is an actor who has unique insights and awe in performance. He has high requirements for himself, so we will also be infected." Zou Ying said of Zhu Yilong, "After the explosion of fire in 2018, he actually had many opportunities to make quick money on variety shows, but he didn’t. He was still working hard as an actor.

　　Zou Ying’s enthusiasm for Zhu Yilong stems from a recognition of the conformity of the three views. Zou Ying, who works in a well-known foreign company, originally belongs to a career-oriented woman who is serious and responsible for her work. She just turned 40 and managed a small team in the company. The leadership and management accumulated over the years also played a great role on her way to idolize.

　　Although it is difficult for Zou Ying to follow the front line and pick up and drop off the plane for work reasons, there are fewer opportunities for the export of first-line materials, but this is precisely an important way for fans to become big coffee in the circle.

　　Zou Ying’s advantage is that she has a more stable economic income compared with young fans, which enables her to support Zhu Yilong’s endorsements and magazines quickly at the first time, or even buy in large quantities at one time, and then send out the surplus products by drawing a lottery to call on other fans to do data, and the popularity and followers in the circle are increasing day by day.

　　Zou Ying opened WeChat to show the zinc scale the WeChat group, QQ group and Weibo group in his hand, and there are five in all. Under normal circumstances, what Zou Ying shares in the group is all about Zhu Yilong’s daily life, such as The Rebel, which was a hit some time ago. Zou Ying will discuss Zhu Yilong’s acting skills and role stories with the fans in the group every day.

　　But when a magazine is on sale or a new spokesperson announces it, Zou Ying will show his passion for doing projects at work on weekdays. "We usually call on the rich to hold the money field, and some people hold the people field. Magazines within 100 yuan hope to have one person and useful products can also be supported, but those beyond their own capabilities will not be respected. " If money is really tight and there is no demand for products, donating a free lunch with 1 yuan money can also be counted as part of Zhu Yilong’s data.

　　And Zou Ying, from Nongfu Spring soda water endorsed by Zhu Yilong to Chopin’s "Ice Cube" series rings of the same paragraph, all got in the bag. Even the coffee machine that was not used at home, Zou Ying moved to the office for colleagues to use for free. In this way, colleagues in the company also volunteered to help her vote for Zhu Yilong.

　　Purchasing power and leadership have become the important reasons why Zou Ying can’t do data and has no time to run the front line, but still has appeal.

　　The main force chasing the front line is young fans.

　　Fang Yu, who just celebrated her 50th birthday, is now mixed with rice circles. However, unlike Zou Ying, she has just retired from work, and she is tired of being a leader, but enjoys the feeling of being an ordinary fan.

　　"Before Sean Xiao’s endorsement was put on the naked-eye 3D screen of the mall, I followed the call of the support club to punch in offline. At that time, many fans were quite surprised to see me." The dialect mentions the scale of zinc. Although there are a lot of "Auntie Powder" in Sean Xiao, there are still a few people who can actively integrate into the circle like her.

　　Double-relaxed eye protector, usmile’s electric toothbrush, unified Manchu dinner, self-heating hot pot with small stove, double-set knife, stone robot … … All Sean Xiao’s endorsements and the same products can be found in Fangyu’s home. Because of the high degree of cooperation and sufficient disposable time, Fang Yu has been regarded as a priority batch of support team members by some big coffee fans of the support club. When organizing offline activities and punching in support occasionally, Fang Yu can have an admission ticket.

　　How does the disorderly idol economy market collide with aunts?

　　After many adverse events, the rice circle actually seems to have been crowned as a "scourge". But in fact, according to the data, the total scale of China’s idol industry may exceed 130 billion yuan in 2020. At the same time, the scale of the new tea market, where the competition is white-hot, is still at the node of breaking through the 100 billion yuan mark.

　　It is not difficult to see that the cake of idol industry is really mouth-watering.

　　According to media statistics, groupies are the largest, most sticky and highest consumption kinetic energy group in the field of pan-entertainment. Among them, female students in first-and second-tier cities, unmarried and rich are the main force of groupies.

　　However, in recent years, with the advent of the new media social era, the frequency of Internet star-making is faster, and the coverage circle is constantly breaking through. According to the results of a questionnaire, 34.05% of the "post-60s" idolize group are willing to spend more than 5,000 yuan for idolize every month, which can be said to be ahead of fans of other age groups.

　　A common way to call fans to do data in rice circles is to draw a lottery.

　　To some extent, middle-aged people with economic strength and mature thinking ability are more responsible for their idolize behavior. However, at present, the fast-running idol economic market and disorderly idolize behavior appear side by side, and the middle-aged people are also facing the mutual integration with the rice circle culture.

　　In this process, the ticket market in the idol economy is chaotic, and the problem is more and more obvious after the middle-aged groupies join. The repeated prohibition of scalpers actually has an important relationship with the irregular professional ethics of the staff in the entertainment market. Zhang Qinglan told Zinc Scale that the scalpers responsible for ticket sales and leading the way actually reached a profit-sharing cooperation with the infield staff who opened the curtain.

　　Take the tickets of 800 yuan purchased by Zhang Qinglan as an example. If she successfully hides and watches the normal performance, the income of 500 yuan will go to the infield staff, and the rest of 300 yuan will go to the scalper who sells tickets and leads the way.

　　In addition to this kind of private transaction that violates professional ethics, irregular wild speculations have also become a big mess. Zhang Qinglan later learned that she bought fake tickets in 800 yuan, some fans spent 500 yuan, and some fans spent 1200 yuan. If she didn’t happen to meet someone who bought them through a unified channel, it would be difficult for her to tell whether the price was normal.

　　Not to mention for a long time, the scalpers in the ticketing market have countless tickets, but fans can’t grab a ticket, which is not unrelated to the above chaos. Under such circumstances, it is more difficult for middle-aged fans like Zhang Qinglan who have not yet stepped into the rice circle to buy regular tickets.

　　With the diversification of Internet star-making methods, the number of middle-aged groupies will continue to increase, and the expansion of fan scale is positively related to commercial value, so the middle-aged groupies with leadership and purchasing power will also receive more and more attention. On the optimistic side, mature middle-aged groupies may bring a new cultural collision to the rice circle culture and eventually form a more benign atmosphere.

　　But on the pessimistic side, the crazy and disorderly idol economy market may isolate middle-aged groupies from the rice circle for a long time, and the coverage and market scale will be affected.

　　But in the final analysis, rice circle culture is not a heinous scourge, but more like a child who lacks spur and discipline.

　　END

　　On July 6, Shu Yuting, spokesperson of the Ministry of Commerce, introduced at a regular press conference that from January to May 2023, China’s service trade maintained an overall growth trend. The total import and export of services was 2,605.54 billion yuan (RMB, the same below), up 10.2% year-on-year. Among them, exports were 1,098.22 billion yuan, down 4.7%; Imports reached 1,507.32 billion yuan, up by 24.2%; The service trade deficit was 409.1 billion yuan.

　　Kevin·Z, an associate researcher at China Service Outsourcing Research Center, told the Economic Information Daily that the growth of China’s service trade continued to improve from January to May, and the import and export volume of services achieved double-digit growth year-on-year. It can be predicted that with the acceleration of international cooperation in China’s service industry, China’s total service trade will reach a new high in the whole year.

　　It is worth noting that while the total volume has maintained rapid growth, the structure of China’s service trade has continued to optimize, and the proportion of knowledge-intensive service trade has increased. From January to May, the import and export of knowledge-intensive services was 1,122.78 billion yuan, up 13.6% year-on-year, accounting for 43.1% of the total import and export of services, up 1.3 percentage points over the same period of last year. Among them, the export of knowledge-intensive services was 656.59 billion yuan, up by 17.2%, and the import of knowledge-intensive services was 466.19 billion yuan, up by 8.8%.

　　In Kevin·Z’s view, this is the concrete embodiment of the continuous improvement of the development quality of China’s service trade. "From the data point of view, China’s knowledge-intensive service trade continued to maintain a rapid growth trend in the first five months, accounting for a steady increase in the total import and export of services, and has become the strength to build a new development pattern of services and promote the high-quality development of trade in the new era."

　　In addition, travel services have obviously recovered. From January to May, the import and export of travel services reached 552.54 billion yuan, a year-on-year increase of 67%, making it the fastest-growing service trade field. Among them, exports increased by 53.4% and imports increased by 68.1%. Kevin·Z analyzed that from January to May, China’s travel service achieved a leap-forward growth, with a year-on-year increase of over 60%, and the recovery momentum was strong, which became an important driving force for the steady growth of service trade.

　　The favorable factors for the development of China’s service trade are still accumulating. Kevin·Z said that with the accelerated popularization of the new generation of information technology and the accelerated development of digitalization and intelligence, digital trade with digital technology, digital products, digital services and data information as its subject matter is booming. China’s digital industry has developed rapidly. At present, it is the second largest digital economy in the world, with a number of digital enterprises with strong international comparative advantages. At the same time, it benefits from a super-large market with a population of 1.4 billion, which provides fertile ground for the development of digital trade and has great development potential. In the future, digital trade will become a new engine for the development of China’s service trade, and will also make greater contributions to the prosperity and development of global trade.

　　People’s Daily Online, Beijing, May 13 (Yang Xi) Recently, the release of the main data of the seventh national census has aroused great concern from all walks of life. Some netizens found that the trend reflected by the census data published this time is inconsistent with that published in non-census years, so they raised some questions about individual data.

　　In this regard, the National Bureau of Statistics answered the above questions and related questions of population statistics.

　　How to count and publish population data?

　　At present, China’s demographic survey mainly has three ways:

　　The first is the national census, which is conducted once every ten years in the year when the mantissa meets "0", and the census data is published in China Census Data.

　　The second is the national 1% population sampling survey, which was conducted in the year when the mantissa met "5", and the survey data was published in the National 1% Population Sampling Survey Data.

　　Third, the national sample survey of population changes, the sample size accounts for about 1&permil of the total population; In addition to the census year and the sampling year of 1% population survey, it is conducted once a year, and the survey data are published in the Statistical Yearbook of China and the Statistical Yearbook of Population and Employment of China.

　　The main statistical indicators of the above three types of population data will be published in the annual data in the database of the National Bureau of Statistics.

　　Why is the trend reflected by census data inconsistent with that published in non-census years?

　　The population in non-census years is calculated according to the sampling survey data of that year. Due to the missing rate of sampling surveys in some years, there will be some deviations in the estimated population as a whole, and these deviations will continue to accumulate with the passage of time.

　　Carrying out the population census once every 10 years can comprehensively find out the number, structure and distribution of China’s population, let us know more clearly the development of China’s population in the past 10 years, and provide extremely valuable data for better studying population issues and formulating population-related policies.

　　So how to deal with this inconsistency? According to international practice and common practice, after the census, the annual data published between the two censuses are generally revised according to the census results, so as to reflect the population development track more truly and objectively. In the sixth national census and the just-concluded fourth national economic census, historical data were also revised according to census data. At present, this work is in progress, and the relevant data will be released on schedule after the revision is completed.

　　Is the population statistics based on household registration or residence?

　　At present, China’s population census and population survey are counted and summarized according to the resident population. The time standard for judging the permanent population is half a year, and the space standard is township, town and street.

　　The resident population is an important basic data for formulating the national economic and social development plan, evaluating the national economic production capacity, and evaluating the welfare level of residents. It has a wide range of applications, such as financial expenditure, urban construction, housing construction, allocation of public facilities, education investment, medical investment and public utility investment, etc., which need to be planned according to the size of the resident population.

　　The registered population refers to the registered population in a certain area, regardless of whether they go out or not, as long as they register their permanent residence in the public security household registration management department. The data of registered population is counted by the public security department. For a long time, China has established a set of perfect household registration statistics and management system, which has played an important role in social management.

　　How is the floating population data counted?

　　Floating population refers to the population whose residence is inconsistent with the township street where the household registration place is located, and who has been separated from the household registration place for half a year or more (excluding the separation of households within the municipal area). The survey indicators used to judge and reflect the floating population include: the place of registration, the place of residence at the time of investigation, the time of leaving the place of registration and the reasons for leaving the place of registration. The National Bureau of Statistics formulates a demographic survey system according to the Statistics Law of the People’s Republic of China, conducts demographic surveys on a regular basis, and publishes major demographic data such as permanent population, birth population, dead population, urban and rural population and floating population.

　　"It only takes a few lines of code to build a regression model." Programmers recognize the performance of Google AutoML and think that the model designed by AutoML is comparable to that designed by machine learning experts. A few days ago, Google engineers introduced the Google AutoML project in China and Silicon Valley respectively.

　　Confused doubts followed — — AI evolved again? ! Already self-developed? Can control their own evolution? Is it to get rid of humans?

　　How many steps does evolution take?

　　AI has indeed evolved, and it can do more and more things and achieve remarkable results. Behind it is the "triple jump" of AI implementation path — —

　　Zhao Zhigang, a researcher at the Big Data R&D Department of Jinan Center of National Supercomputing, said: "At first, we used mathematical formulas and ‘ if… … then’ Wait for the statement to tell the computer what to do in the first step and what to do in the second step, teach it by hand, and then give the machine N groups of inputs and outputs. The rules or laws in the middle are learned by itself. "

　　"Before, many smart minds spent their whole lives studying how to extract effective features." Mo Yu, CTO of Smart Point, which focuses on intelligent shopping guide dialogue robots, explained, "The invention of neural network algorithm and the emergence of deep learning technology have made AI evolve to 2.0, and the work of extracting features is carried out by AI itself, and our work has also changed accordingly."

　　It is easy to explain the transition from "1.0" to "2.0" with the model of mathematical function: if the tasks of image recognition, semantic understanding and chess playing are all regarded as different Y=f(X), that is, the input picture, voice or chess move of "cat" is "x", and the output cat, answer and chess move is "y". Before deep learning, people find the formula corresponding to function F through their own analysis and tell it to AI. After deep learning, people input a lot of correspondence between x and y, and AI finds the formula corresponding to function f by itself.

　　"The specific content of the function F found by AI may be better than that found by humans, but humans don’t know it, just like a black box." Mo Yu said, "But the form of F is designed by AI researchers through research. If deep neural network is used, the modules in the network and the organization between modules are also designed in advance."

　　With the maturity and popularization of deep learning technology, there has been a specific pursuable experience in model construction. "The release of various common neural networks has made the threshold for employment lower and lower. Some ordinary model construction and optimization, just graduated students can get started in online learning tutorials. " Zhao Zhigang said.

　　When modeling becomes a learnable skill, AutoML appears. What it can do is the model design work of AI researchers. "It will help different companies build artificial intelligence systems, even if they don’t have extensive expertise." Google engineers recommend this. AI successfully evolved to 3.0.

　　In fact, AutoML still replaces the work that human beings can extract experience. "If people described a set of ‘ Road network ’ With the technical assistance of deep learning, the machine can find the optimal path as quickly as possible; Then AI can now design its own road network. " Zhao Zhigang was concise.

　　It can be seen that both deep learning and AutoML only replace the work that some groups of human beings have studied thoroughly. "What machines can do, try not to work by hand" is the life creed of many programmers, which gave birth to AutoML. Based on the same creed, Microsoft developed DeepCoder. "It can be used to generate programs that satisfy given input and output." Mo Yu said, but its performance is not satisfactory at present, and only some simple programs can be written.

　　Who is "God"

　　There is no doubt that the answer is human.

　　Since AI has evolved to a higher level of model design, what changes have taken place in the "hand of God"?

　　"An alchemist", Mo Yu vividly talked about his work in two words. "Smart is a professional intelligent customer service. The work of R&D personnel mainly focuses on problem modeling (how to turn actual problems into problems solved by artificial intelligence technology) and algorithm optimization (how to improve the effect of artificial intelligence algorithms)."

　　"refining" means constant debugging and improvement. "For a specific person, the more you throw your temper, the better. The more accurate the answer, the better." Mo Yu said, "Our X is the customer’s question, Y is the reply of the robot customer service, and the middle function F needs training."

　　This is not an easy task. If we divide the experience of human society into three categories: definite rules with formulas, knowledge that can be expressed in words, and feelings that can only be understood but cannot be expressed. The last category is the most difficult to ponder.

　　"Therefore, we try to build a perfect closed-loop feedback, understand the preferences of specific users, and finally achieve what they like through the expression of emotions and interests." Mo Yu said, "At present, it is in the stage of man-machine collaboration, but the acquisition of more and more samples will help our intelligent customer service to give accurate and pleasing answers."

　　It can be seen that not all fields are suitable for AI’s self-development. For example, in the aspect of problem modeling, how to abstract practical problems into machine learning problems can not be completed by AI. In the stage of AI2.0, R&D personnel also need to design the form of function F manually.

　　So, what will be the future of AutoML popularization?

　　"Humans are liberated from lower-level jobs." Zhao Zhigang said, "If the model design can be done by AI, then AI researchers will explore more the design of the basic modules that make up the model."

　　"Developing AI models with AutoML is similar to children playing with ‘ Lego ’ Toys. " Zhao Zhigang put it in simple terms, and the designers of Lego disassembled the whole world into detailed modules, so that everything could be used and then combined into complex models. The higher level of human work is to find basic units, that is, modules, for AI in different fields. For example, in the field of image recognition, humans have designed various modules such as convolution and pooling. "AutoML can build a model based on this, and constantly adjust the module combination to obtain a more reasonable output. The finer the module, the more versatile it can be, and the more self-developed AI can be used. " Zhao Zhigang said.

　　Extended reading

　　 Where are the talents needed by the industry?

　　Alleviating the shortage of talents is the main selling point of AutoML. "AI systems are blooming everywhere, but AI talents are far behind." Google explains why AutoML is indispensable. What is the current status of AI talents?

　　In 2017, the Global AI Talent Report and the BAT Artificial Intelligence Talent Development Report were released one after another. "The shortage of AI talents is real." Xu Wenjuan, vice president of Shengshi Investment Group, said, "The shortage of talents in start-up and development enterprises is particularly serious. From the current global perspective, the United States has the largest number of AI talents, and China’s AI talents can’t be compared with it in terms of number of people and experience. "

　　Zhao Zhigang has the same feeling: "China’s AI field is short of veterans, experts, generalists and top masters." The optimization and debugging of the model requires experience, the exquisite design of the model requires superb skills, and the application of AI in various industries requires compound talents. In addition, there are only a handful of top talents leading the development direction of AI, and most of them are abroad.

　　Xu Wenjuan introduced that China has the most AI talents in BAT (Baidu, Ali, Tencent). Generally, there are several kinds of background experiences of such talents, such as returnees, BAT work experience, or from universities or research institutes.

　　"AI self-development should not be able to replace people’s work in the short term, and there is still a long way to go." Xu Wenjuan said. Zhao Zhigang analyzed from an academic point of view: "Only when human beings design AI models in different application fields and further decompose them into a series of general modules, such as the periodic table of elements in chemistry, DNA and RNA in biology, can this self-development have more applications."

　　According to the Southeast Network (Reporter Feng Chuanye correspondent Song Yaxin), the "May Day" holiday is coming, and many car owners have already made travel plans. The reporter learned from Fujian Expressway Energy Company that Fujian Expressway has laid out charging stations in more than 100 pairs of service areas and built more than 900 charging piles, of which the coverage rate of fast charging stations is as high as 88%, and the charging service network of expressway intercity traffic in the province has basically taken shape.

　　This year’s "May 1 ST" holiday arrangement is: April 29 to May 3, a total of 5 days. Free passage time is five days during the May Day holiday in 2023 (from 0: 00 on April 29th to 24: 00 on May 3rd), and Fujian Expressway will continue to implement the free passage policy for passenger vehicles with less than 7 seats (including 7 seats).

　　The high-speed department predicts that the public’s willingness to travel during the "May 1" Golden Week this year is very strong. Combined with the comprehensive analysis and judgment on the changes of expressway traffic in the whole province during the May Day holiday in recent years and the Qingming holiday this year, it is predicted that the overall expressway traffic in our province will rise sharply during the May Day holiday this year, which is expected to break through the level of the same period in previous years and hit a new record high. The travel groups are mainly long-distance inter-provincial tours and short-distance trips to go on road trip. It is suggested to plan the route scientifically and rationally stagger the peak trips.

　　In order to facilitate the travel of electric car owners, Fujian Expressway has sorted out the list of service areas where charging stations have not yet been laid out, helping car owners to plan their trips in advance, avoiding entering the service area without charging stations by mistake and improving charging efficiency.

　　The service area of the charging station has not yet been laid out as follows:

　　Fuzhou area: Longtian service area of Fuzhou-Xiamen Expressway and Wutong service area of Puyan Expressway;

　　Zhangzhou area: Huangtian service area of Pingmei Expressway, Banzi Yutang service area and Meifeng service area of Guping Expressway;

　　Longyan area: Rentian Service Area of Zhangwu Expressway, Ancient City Service Area of Xiamen-Chengdu Expressway and Tufang Service Area;

　　Sanming area: Fengxi service area, ancient ginkgo service area of Shaxia Expressway and Dajin Lake service area of Puwu Expressway;

　　Tips for using charging piles

　　1. During the charging process, the vehicle should be parked and turned off, and it is not allowed to move at will.

　　2. Check the charging pile, charging cable and charging gun for obvious appearance damage before charging the gun. If there is any damage, charging should be prohibited.

　　3. When charging, the charging gun should be inserted to the end, otherwise the equipment protection function will be prohibited from being electrified.

　　4. After starting charging, the charging equipment and lines are electrified at this time. Despite multiple protection measures, you should try to avoid touching the charging equipment again.

　　5. It is forbidden to plug and unplug the charging gun forcibly when the charging is not over, and it is forbidden to press the emergency stop button in non-emergency situations.

　　6. Non-professional operation and maintenance personnel are strictly forbidden to disassemble or modify the charging equipment.

　　Situation of high-speed power exchange stations in the province

　　In cooperation with Weilai Energy Company, Fujian Expressway Energy Company has operated five power stations in three pairs of service areas with large traffic and high power demand in the province, including one second-generation power station and four third-generation power stations.

　　Compared with the second-generation station, the third-generation power station has the advantages of higher efficiency, stronger service and smarter operation. It only takes 3-4 minutes to complete the power exchange, and the daily service times can reach 408 times, which can realize the functions of calling vehicles and automatically changing power, and can comprehensively improve the experience of power exchange owners.

　　Tips for using Weilai Power Station

　　1. Navigate to the nearest power exchange station by calling NOMI, and the locomotive system will prompt whether it is necessary to make an appointment for power exchange in advance, click OK, and then go directly to the power exchange station;

　　2. After arriving at the power exchange station, a power exchange prompt will pop up on the central control panel, and the owner can choose to park automatically and enter the power exchange station, or back up by himself and let the power exchange station staff back up and enter the power exchange station;

　　3. After the vehicle stops in the power exchange station, it will automatically start to change power. After the power exchange is completed, the vehicle will give a prompt, and then it can directly drive out of the power exchange station.

　　In the next step, Fujian Expressway will encrypt the network layout of power stations, and strive to achieve one power station every 100 kilometers of expressway. It is estimated that 11 power stations will be added to Fujian Expressway during the year, which will radiate the sections of Shenhai Expressway, Jingtai Expressway and Changshen Expressway in the province. This will greatly enhance the convenience service capacity and provide a strong "green power support" for high-speed electric vehicles to travel to Fujian Expressway.

　　Line up for spicy food.

　　Tempting Gansu mala Tang.

　　"Bouquets of vegetables" are one after another, and enthusiastic diners are one after another. After Tianshui Mala Tang went out of the circle, this "sky-splashing flow" also began to flock to Lanzhou, and the passenger flow of major Mala Tang shops in the city continued to rise obviously. Embracing this wave of traffic dividends, on March 20th, famous local restaurants in Lanzhou took advantage of the situation to offer a new "Gansu Mala Tang" and add another fire with innovative dishes. Even the University of Science and Technology Beijing, thousands of miles away, issued an official announcement, "The campus canteen window, authentic Tianshui Mala Tang in Gansu, is officially launched"!

　　A Lanzhou hot spicy dip famous store huo Shang Jia huo

　　When visiting Lanzhou, Jin Lan Mala Tang in Anning District must be on the must-eat list.

　　At noon on March 19, looking at the endless diners, Ms. Chen, a citizen of Lanzhou, lamented: "Jin Lan Mala Tang, which is deeply loved on weekdays, has become more popular recently!" This is an old-fashioned Mala Tang shop in Lanzhou. The proprietress’s name is Wen Jinlan, and she is from Longnan, Gansu Province. She has been here for more than 20 years. After the hot spicy dip in Tianshui, more and more diners came here, and sometimes they even had to wait in line for an hour to eat.

　　In order to meet the huge passenger flow, it is normal for Wen Jinlan to get up early for nearly 20 hours every day. The reason why it is popular, in the view of the proprietress Wen Jinlan, is because of "popular taste, everyone likes it". The raw materials such as Gangu pepper, Wudu Dahongpao pepper, vermicelli specially customized from Dingxi and grain vinegar produced nearby have jointly contributed to the mouth-watering "spicy and hot".

　　"A large pot of vegetables, all kinds of ingredients wrapped in red juice, a spoonful of crisp sour radish, and the smell of oily spicy seeds between chopsticks directly hit the taste buds." Every meal, Yanji Mala Tang in Zhengning Road, Chengguan District, all the tables inside and outside the store are full. Many people ask, after more than 30 years of opening, people are so popular that there must be an exclusive secret recipe, right? Mr. Zeng, the boss, said frankly: "My wife and I are out-and-out Jianyang people in Sichuan. We have lived in Lanzhou for decades. We improved and adjusted the proportion of juice according to the tastes of local people, which reduced the hemp degree of pepper. It brings together Gansu local materials such as Dingxi Kuanfen and Gangu Chili, forming a unique flavor of Gansu Mala Tang. "

　　B Lanzhou local catering enterprises innovate dishes.

　　On March 20th, Duanji Hotel in Yantan, Lanzhou officially launched the new dish "Gansu Mala Tang". Yang Guoyan, Chairman of the Folk Food Committee of Longcai Association and Deputy General Manager of Lanzhou Duanji Catering Management Co., Ltd., told Benben News reporter: "In order to meet this wave of traffic, we have developed a new dish close to Tianshui Mala Tang, with ingredients such as Gangu Chili, Dingxi Kuanfen and Qin ‘an Zanthoxylum. As a Longcai hotel, our goal is to create a ‘ Ganwei hot spicy dip ’ The alternative ingredients will be more extensive, adding lily, yak meat and so on. " Yang Guoyan said that many employees in the store are from Tianshui. Through repeated trial production for many days, this new product has been officially launched.

　　"After Tianshui Mala Tang is on fire, how can we seize this wave of traffic and continue to undertake this heat to Lanzhou? In fact, we still have to work hard on product innovation." Yang Guoyan said, "Gansu is more delicious than mala Tang, Wuwei ‘ Three sets of cars ’ , Zhang Ye ‘ Stir-fry firecrackers ’ , Longnan stirred up the group … … Longshang cuisine has a long history. How to make use of this mala Tang craze to make all kinds of snacks in Gansu known to more people and promote them to the whole country requires not only the help of the cultural tourism department, but also the joint efforts of the catering industry and other departments. "

　　C "Gansu Mala Tang" online orders skyrocketed.

　　According to the data of Meituan, since March, the search volume of keywords related to "Gansu Mala Tang" has increased by 18.5 times from last month, and the number of public comments has soared by 13.2 times. The take-away orders of Gansu Mala Tang increased 66 times from last month. Beijing, Xi ‘an, Jinan, Shanghai and Tianjin are the top five cities in search volume.

　　At the same time, the popularity of Tianshui Mala Tang has also driven the growth of local cultural tourism consumption. The booking volume of travel orders in Tianshui City, Gansu Province increased by 71.8% compared with the same period of last year. Among them, the order volume of hotels and homestays increased by 73.6% year-on-year, and the order volume related to scenic spots increased by 216.8% year-on-year. Maijishan Grottoes, Fuxi Temple, Maijishan Hot Springs, Xianrenya and Yuquan Temple are the top five scenic spots in terms of order volume. Shaanxi, Henan, Jiangsu, Guangdong, Ningxia, Beijing and Sichuan are the top provinces and cities in the source of off-site orders.

　　On various social platforms, many netizens called for authentic Gansu Mala Tang to be eaten in their hometown, and called on Tianshui people to open stores in their hometown. Some physical stores that see business opportunities are trying to seize the opportunity … …

　　Gansu Beijing Office, located in Beijing Feitian Mansion, has recently put up "Gansu Mala Tang", attracting many netizens to taste the punch card. And a female shopkeeper from Tianshui also decided to open a Gansu Mala Tang restaurant in Sanlitun, one of the hottest business districts in Beijing, which is expected to be officially opened in half a month.

　　On March 19th, University of Science and Technology Beijing issued a document saying that "Gansu Tianshui Mala Tang" will be launched in the school cafeteria at noon. In order to reflect the authenticity, the school emphasized that "soul juice" is all from Gansu, and it brings together two ingredients of Tianshui, namely Gangu pepper and Qin ‘an pepper. The potato powder is elastic and smooth, Gangu chili pepper is full of oil, and the most delicious thing is the intersection of fresh hemp and Qin ‘an pepper. In fact, as early as 2012, the school established a fixed-point assistance relationship with Qin ‘an County, Gansu Province, and purchased Qin ‘an pepper every year. This year, a new potato powder procurement project was added, and the canteen master went to the local area for research and study, bringing students a better experience.

　　Searching with "Gansu Mala Tang" as the key word through Tianyanchao platform, in the past three months, there have been more than 200 new Mala Tang shops in China. Among them, since February this year, there have been more than 150 newly opened Gansu Mala Tang shops in China. According to the data of Tianyancha Professional Edition, up to now, there are more than 9,600 mala Tang related enterprises in Gansu, while there are nearly 900 related enterprises in Tianshui City alone.
