    With the dream of "automobile power", he led the team to step into the "no man’s land" of scientific research again and again, overcome key core technologies, solve the problem of "stuck neck", and was determined to build "people’s car" with hard core "Chinese core".

    He and his colleagues are quite responsible, and it is difficult to attack the "core". They have successively completed the independent development and mass production of software and hardware of more than 30 controllers, and completed the loading application of 40 million domestic chips on the whole vehicle.

    Thanks to the efforts of him and his team, Wuling Hongguang MINIEV, known as the "people’s scooter" and the world’s single-model sales champion of new energy vehicles for seven times, has increased the localization rate of chips from 6% to 93% in three years.

    As a doctor of "returnees" majoring in combustion science, he has devoted himself to car-making for thirteen years, and always "burns" his burning dreams in the most efficient way in the process of transformation and cross-border.

    He is the "Eight Gui Model", the deputy general manager of the technical center of SAIC-GM-Wuling Automobile Co., Ltd. (hereinafter referred to as SAIC-GM-Wuling), the chief technology officer of control and software, and the deputy director of Guangxi New Energy Automobile Laboratory and professor-level senior engineer Liu Changye.

   "Black! Open up the second pulse of industrial governor. "

    "emergency! Urgent! "

    Put the hour hand back to the end of February 2022. Although it is early spring, it is still chilly. There is a tense atmosphere in SAIC-GM-Wuling. Due to the sudden interruption of the supply of imported chips, the steering controller of key components could not be supplied, and a large number of cars on the assembly line could not be off the assembly line.

    At that time, the "chip shortage" was sweeping the automobile industry. The price of some key components has skyrocketed. Although the price has doubled, it is still hard to find a "core", resulting in a shortage of controllers. SAIC-GM-Wuling introduced more than 40 measures to ensure supply before and after, but it still can’t completely solve the shortage of key components.

    "Before 2019, the controller was regarded as a’ black box’ by everyone, and it was purchased as a whole with parts. We don’t know its internal structure, let alone what chips are carried inside." Liu Changye said that it was not until the "chip shortage" spread in 2021 that enterprises deeply felt the pain of "sticking their necks".

    Production is facing stagnation, and engineers are in a hurry.

    I would rather fight hard than endure it. The grim situation has inspired everyone’s spirit of struggle and aroused the responsibility of "the more difficult it is, the more forward it is".

    "Black! It must be black! Key core technologies must be firmly in their own hands. " Liu Changye thought: "Perhaps the pain point of’ chip shortage’ is the key point to get through the second pulse of industry."

    As a result, the team immediately launched the "Black Box Action" to crack the internal mystery of the "black box" and determined to kill a bloody road on the unknown road of making domestic cars with domestic chips.

    The news of all parties was summarized in the technical center, and one of them attracted the attention of the team: a university in Shanghai with long-term and in-depth cooperation with SAIC-GM-Wuling has made a breakthrough in the application of domestic chips. Full of expectations, Liu Changye immediately went to Shanghai from Liuzhou with a research team of 20 people, and "chased the core" at full speed.

    "Our technology has no precedent for industrialization, and you are about to step into a’ no man’s land’." College experts told Liu Changye.

    The difficulties are far more than that. At that time, the COVID-19 epidemic in Shanghai was tight, so they had to move the scientific research equipment to the hotel, turning the hotel into a crucial place for the team, where they lived and ate. Lacking a testing ground, the underground parking lot became their testing ground.

    After fighting all night and repeated testing, the problems in the software code were found out one by one and corrected one by one. At the same time, Liu Changye also keeps in touch with suppliers, universities and Liuzhou base in production and logistics.

    Race against time. In just 8 days, the software development was completed, which solved the obstacle of related software from laboratory to industrialization. In another 6 days, 100% of the steering controller with domestic chips will be on the production line.

    This speed has shocked the industry.

    In the face of praise from all parties, Liu Changye, who started to set up a team to try to develop controllers at the end of 2019, was not satisfied. "We have mature and complete parts verification capabilities and technology industrialization capabilities, so that the technology of the institute can enter the market and enter thousands of households. There are still many ways to go."

    According to relevant data, in 2022, the global production will be reduced by 4.4 million vehicles due to chip shortage. The success of SAIC-GM-Wuling’s "Black-Breaking Action" ensured that 400,000 vehicles were successfully rolled off the assembly line, driving sales revenue to exceed 10 billion yuan.

    The "Operation Breaking the Black" has boosted everyone’s confidence. After that, Liu Changye led the team to further break through the technologies of software algorithm, domestic chip application and vehicle calibration, and successively completed the independent development and mass production of software and hardware of more than 30 controllers, realized the domestic substitution of 486 chips, and accumulated 40 million domestic chips in the vehicle. Loading application.

    Wade through the deep water and gnaw hard bones. SAIC-GM-Wuling not only solved its own technical problems, but also made domestic chips have rich application scenarios in the field of automobile manufacturing, which promoted the rapid upgrade iteration of domestic chips for vehicles and accelerated industrialization.

   "The software has no accidental failure"

    "There is no accidental failure in the software, and the probability of failure is 0, which is 100%." This sentence of Liu Changye is deeply in the heart of Zhang Zhongjun, the electronic architecture integration manager of SAIC-GM-Wuling Technology Center.

    In the traditional automobile manufacturing process, due to mechanical errors and other factors, there are occasional failures. In a new model development test, the body controller of one of hundreds of cars failed. As usual, Zhang Zhongjun attributed this to "accidental failure" and wrote it into the report.

    Unexpectedly, this was severely criticized by Liu Changye: "There is a problem with the software of this car, and it will definitely appear in other cars! We must find the cause of the problem and give a solution. "

    Although he didn’t quite agree with him, Zhang Zhongjun did as required. Because he knows that Liu Changye’s self-requirements and requirements for product quality are extremely strict.

    "We checked for a week and found that there was a mistake in the software program. We improved the scheme." Seeing the new report submitted by Zhang Zhongjun, Liu Changye finally smiled with satisfaction.

    The phrase "there is no accidental software failure" deeply affects the team-you must not let go of any suspicious problems.

    To overcome difficulties, we need courage and perseverance, and we need to find the right path.

    In November last year, when developing the key safety controller, Wang Wei, the test and experience manager, encountered an unprecedented problem. "This test is bulky and difficult. How to speed up the completion as soon as possible to reduce the supply pressure of the production line? How to solve the problem of high cost of collision test? This makes us feel at a loss. " He said.

    Just when Wang Wei was at a loss, Liu Changye told him, "Don’t be afraid of difficulties, do the right thing."

    Liu Changye broke through the traditional "hard-hitting" crash test method, took everyone to collect more than 30,000 sets of real vehicle data, conducted simulation tests through signal simulation, completed the target task in 10 days, and built a complete signal simulation test system.

    "Software testing is not only qualified acceptance, but also repeated verification in various complex environments, reverse analysis of all possibilities, and efforts to ensure safety and stability." Liu Changye’s words helped Wang Wei find the way to work and the mission of struggle.

    The ancients said, "Who dares to be wrong if the child rate is positive?" With Liu Changye leading by example and setting an example, the team worked as one, and the technical problems of "sticking the neck" were broken.

    "He proposed a long time ago to promote the localization of chips with decoupling thinking, eliminate the problem that chip software and hardware cannot be matched among different enterprises, and make the joint innovation of politics, production, learning, research and use more efficient and forward-looking. At present, the controller and chip application sub-laboratory of Guangxi New Energy Vehicle Laboratory is promoting scientific research innovation and technical iteration under such a concept. "

    "He has a huge knowledge reserve and is called a generalist in science. Once the data didn’t match, he personally deduced the mathematical formula. "

    "He is always full of energy. He forgets to eat and sleep when he does a project. He is often the last person to leave the office. Sometimes he replies to the questions raised by the team on WeChat at one or two in the morning."

    "He is rigorous and meticulous, pursuing Excellence, and his positive and optimistic scientific research attitude infects everyone in the team."

    ……

    In the interview, colleagues outlined the image of this "benchmarking" scientific research worker.

    In fact, Liu Changye is not a talented player born to build a car. From studying physics and combustion to studying engines, to focusing on the development of new energy vehicles and solving the problems of controller development … He constantly challenges himself, which is the intensive work and study for years. Those foreign language documents that have been turned over have been repeatedly tested for thousands of times. The lights that are always on in the office at night and the gray hair on his head are the testimony of the "post-80 s" technical expert’s diligent work and courage to climb the peak of science and technology.

   "Fighting spirit, changing the unknown"

    Interview with Liu Changye, we made an appointment at 8 pm. Through the window of Liu Changye’s office on the 5th floor of Wuling Hongguang Building of SAIC-GM, we can see that he is having a heated discussion with a group of people. It was not until half an hour later that the meeting ended that he came out and said apologetically, "Sorry to have kept you waiting!" "

    Walking into his office, there was a display screen for demonstrating PPT, two pieces of blue tooling, and various materials on the desktop … The most special thing was the form with a wall. "Key Controller Project Plan" and "Key Component Development Plan" … On the table, there are many key nodes, target tasks and development progress, and the time span is from 2020 to 2024.

    "When I have a sip of water, we’ll talk in two minutes." When we sit down, Liu Changye said. At this time, I saw Liu Changye’s eyes through black-rimmed glasses, which was a little tired.

    Before joining SAIC-GM-Wuling, Liu Changye studied physics and combustion, and went to Madrid University of Science and Technology and Delft University in the Netherlands to study. He was selected as the first batch of "National Project for Building High-level Universities" to jointly train doctoral students and went to Lund University in Sweden for further study.

    As we all know, new energy vehicles have no internal combustion engines. However, this expert who studies combustion is the first group of people who invested in the development of new energy vehicles by SAIC-GM-Wuling. Thanks to Liu Changye’s long-term study experience, he has developed his strong learning ability and logical thinking, which has become two sharp tools for him to carry out scientific research in the future. In his view, the internal logic of innovation and research and development are all interlinked.

    When studying in Sweden, the engine laboratory was next to his laboratory. "I was fascinated by the ingenious design of the engine in the laboratory. It was simply a perfect work of art." Speaking of which, Liu Changye’s eyes sparkled.

    After that, Liu Changye often went to the laboratory next door to observe. During the long-term exchanges, he deeply felt the gap between China and developed countries in car-making technology, and the seeds of dreams were quietly sprouting in his heart.

    "My parents are industrial workers and always respect and support my choices." The cold wind in Sweden gradually receded, and the moat of the castle began to shine, and winter went to spring. Standing at the crossroads of life, Liu Changye was a little confused in his heart until he met this engine. "I grew up in Liuzhou’s strong industrial and cultural atmosphere and watched the automobile industry surge. I am also the son of a worker, and I am always eager to use what I have learned. " Liu Changye immediately decided to go back to Liuzhou to work and devote himself to automobile research and development.

    In 2010, Liu Changye joined SAIC-GM-Wuling and was the second doctor recruited by the company.

    Nowadays, it has become the norm for "returnees" to return to their hometowns and doctors to enter the factory. Among the 4000 engineers in SAIC-GM-Wuling Technology Center, there are 26 doctors.

    Among the four apprentices Liu Changye is currently taking, there are two doctors. He also integrated the enlightened education of his parents into the process of mentoring.

    Alvin Wong, a post-90s doctor, is an expert in software testing and one of Liu Changye’s apprentices. "He always works late, but he never asks us to do the same." In Alvin Wong’s eyes, Liu Changye’s "being a teacher and a friend" is an example for learning and a yardstick for correcting mistakes.

    "When I first entered the company from campus, I always wanted to prove myself. In order to make an annual summary report, I want to present it in a bright way. " Alvin Wong said. However, Liu Changye told Alvin Wong that the road is simple, and it is not necessary to engage in fancy things in scientific research, but to be down-to-earth.

    Adhering to the fine tradition of "working hard and striving for self-improvement" and aiming at mastering key core technologies, SAIC-GM-Wuling is accelerating its global layout on the new track of new energy vehicles. A number of new energy vehicles, represented by Wuling Air ev, which shined brilliantly at the G20 Summit held in Bali, Indonesia in 2022, are shining frequently on the international stage with the expectation of Liu Changye and the team, and realizing the output of technology, standards and industrial chain.

    Under the leadership of Liu Changye, SAIC-GM-Wuling has set up a high-level scientific research team in the field of localization of automobile controllers and chips. On the stage of international competition, Liu Changye firmly believes that the self-controlled technology and reliable product quality will make the road for China automobile to "go out to sea" wider and flatter.

    In Kan Kan, Liu Changye described his dream of "automobile power".

    "Sorry, actually, I haven’t had dinner yet, and my brain can’t turn around …" At the end of our interview, Liu Changye said apologetically again. Only then did we notice that the sweets and biscuits on the table were used to satisfy his hunger when he was busy.

    Fighting spirit, changing the unknown.

    Out of Liu Changye’s office, there is such a sentence printed on the head-on wall. Looking back on the interviews in the past few days, from Liu Changye and his team, we can see the hope and confidence of China automobile industry to lead the world in the new energy track. (Li Bin Rongyao)

Phoenix Auto News, recently, we learned from the official that the domestic Cadillac XT5 will be officially launched at the Beijing Auto Show in April 2016. It is reported that the domestic Cadillac XT5 will be equipped with a 2.0T engine.

The Cadillac XT5 is the successor to the Cadillac SRX. The new car features a new Cadillac design language, with sharp headlights and LED daytime running lights that extend from the headlights to the front bumper, making it very personalized.

The LCD screen of the CUE system has been upgraded to a larger size, and it still uses touch control to support Apple CarPlay. The specific use experience will not be known until the real car experience. Safety configurations include parallel prompt, lane keeping, adaptive cruise, front touch warning with automatic braking, etc. Convenience configurations such as automatic parking will also appear in the configuration menu of the XT5.

In the interior part, the Cadillac XT5 adopts a design language similar to the appearance, and the overall shape is very layered. The new car uses a four-spoke multi-function steering wheel, and a larger LCD screen is used in the center of the instrument panel. In addition, the new car is also equipped with a new version of the CUE system, which is compatible with Apple CarPlay and Android Auto systems.

In terms of power, considering the demand of the Chinese market, the Cadillac XT5 will not be equipped with the 3.6L engine used in overseas models, but will be replaced by a 2.0T engine.

On January 5, the news that actor Ming Dao’s brother committed suicide after strangling his wife and children shocked the Taiwan entertainment industry.

It is reported that the Neihu police in Taipei City received a report from the public on the 5th, saying that three bodies were found in the mountainous area of Antai Street with ligature marks on the neck. After receiving the report, the police dispatched supervisors and sealed off the scene, confirming that the three deceased were a husband and wife surnamed Lin and a child, and the male deceased was Ming Dao’s brother.

The police found in the phone of the man surnamed Lin that he had revealed his intention to die to a friend, saying that he owed tens of millions of dollars in debt, and his family blamed "I don’t want to live for a long time, I want to die". The police speculated that the man surnamed Lin strangled his wife and son because he could not pay the debt, and then hanged himself.

Then the police also revealed more details.

On the 5th, at noon, Mingdao brother, his wife Chen, and his junior son (12 years old) rode a motorcycle to the front of the Ford Palace, Lane 191, Antai Street, Inner Lake District. They parked the locomotive, and then followed the mountaineering trail next to them. After walking about 200 meters, Lin Nan walked into the barge next to the mountaineering trail and went down to the bamboo forest next to the hillside.

Lin Nan tied his son and wife’s necks with an electrician’s strap and strangled them to death. The children’s necks oozed blood on both sides of their necks, and Lin Nan hanged himself. The means are very fierce and cruel.

The Mingdao brother seemed to have already thought about the funeral. When the police arrived, they found that his mobile phone was fully charged and unlocked. Then the police found his conversation with his friends and revealed that he was in debt and was forced to pay. He bluntly said that he did not want to live.

After the incident, Mingdao responded to the incident and confirmed the news that his brother had committed suicide with his wife and children.

Mindao said: "The current situation in Mindao is very shocking and sad. I don’t know anything about this case and am trying to understand what happened. However, because I respect the law that the prosecutors’ investigation is not public, I can only speak to the police in the future. I will try my best to assist the prosecutors in sorting out the truth and comfort the family."

Mingdao’s father has also arrived at the police station, and a female family member has also appeared. It is reported that she is Mingdao’s sister. She is extremely unstable and burst into tears at the scene.

In this regard, netizens felt sorry for Ming Dao, feeling that he was too unlucky to meet this family.

In 2013, Mingdao’s brother borrowed money everywhere in the name of his younger brother. The creditor once had an event to ask Mingdao to collect debts in person. Mingdao could only repay 6 million of debts for his brother. At that time, Mingdao once described his brother as a "time bomb in the family" at a press conference. However, Mingdao’s brother still did not stop his gambling habit. In 2016, the same situation occurred. Mingdao had to issue a statement to make his brother responsible.

It was well known that Ming Dao’s family was not well off. His parents supported the family by selling vegetables in the early years, but later became indebted due to business failure. He made his debut at the age of 18 to pay off debts, and then took charge of the family’s life.

Of course, the reason why Ming Dao was so caring and attentive to his brother was also because he had been kind to his brother. It is reported that Ming Dao once revealed that he had muscle weakness when he was in kindergarten, and he relied on his brother to carry him to and from school every day, which made him very grateful. When his brother grew up and got married, he also took care of the marriage expenses. It can be seen that the relationship between brothers is very deep.

Now that such a thing happened, it was very surprising. But as netizens said, it was not a disaster for his wife and children, and Brother Mingdao’s extremism was really shocking.

　　"Such a famous store has also been taken offline. I used to order takeout for big brands, and this can also be’hit ‘."

　　Liu Changsheng, a Beijing resident sitting opposite the reporter, looked helpless and shook his head repeatedly.

　　Because there are old and young, Liu Changsheng will choose to order takeout to his home when he is really busy with work. It is also because there are old and young at home that Liu Changsheng is extra cautious when ordering takeout, and he was even ridiculed by his wife as "ink". His tenet is that expensive, eaten, and chain brands are the best.

　　However, even so, Liu Changsheng "broke down" when he saw the offline list online.

　　This list comes from the Beijing Municipal Food and Drug Administration and is a list of governance since December 2016. 225 unlicensed catering stores on Baidu takeaway, Meituan takeaway, and Ele.me were taken offline, including many well-known or chain restaurants.

　　"Where to go? Maybe takeout has become an indispensable part of urban life, but so worried, how to continue?" Liu Changsheng’s question may also be the question mark of many people in 2017. The answer to this question needs to be given by takeaway platforms, merchants and regulators.

　　The platform shirks

　　In addition to considering the health of his family, the reason why Liu Changsheng ordered takeout cautiously also came from his own experience.

　　"One day in July last year, I ordered takeout from a takeaway platform. After eating, my stomach started to overwhelm at 3:00 in the morning. I had abdominal pain and diarrhea and wanted to vomit… I didn’t eat anything else at night except crayfish, water, and chewing gum (delivered by the seller). The next day, I continued to have diarrhea, abdominal pain, nausea and nausea, and I couldn’t vomit." Speaking of that night, Liu Changsheng said "it’s just unbearable to look back on".

　　However, the focus is on the back, but there is no way to complain about a bad stomach.

　　"The platform’s complaint is completely a decoration, and when I tell the store about it, I don’t even admit it. It seems that my bad stomach is my own fault, not theirs. Because it’s just gastroenteritis, that is, diarrhea, abdominal pain and vomiting caused by unclean food, the average person will recover without medicine within 48 hours. Neither the merchant nor the platform seems to pay attention to it, and if I can make a sloppy eye, I will never admit it." Liu Changsheng said, "I can only treat myself as unlucky, who calls myself poor physique and can’t afford to eat unhygienic crayfish…"

　　However, there are also competitors, such as Su Meili, a white-collar worker in Beijing.

　　The same is to eat a bad stomach, and the takeaway platform is also inactive, repeatedly shirking.

　　"I had a fight with the platform and said I was going to report it. The platform finally gave me a 60% discount coupon," Su Meili said. "I thought it was fine at the time, but when I placed an order of 50 yuan, I found that it was only reduced by 8 yuan."

　　The next thing, Su Meili described it like this: Fortunately, my math is good and I was not deceived, so I contacted customer service immediately. The customer service said that the coupon is capped at 8 yuan, and the attitude is tough.

　　"My original intention was actually to say’sorry ‘. The platform made a mistake and refused to apologize?" Su Meili said, "Later, the other party found a supervisor and talked for an hour, but still did not give a solution."

　　The final result was that Su Meili called 12315. The staff believed that according to the regulations, the platform should compensate 12 yuan for the price difference, and said it would help Su Meili coordinate the solution.

　　"After I finished defending my rights, I directly deleted the takeaway platform. The internal management is so chaotic, and the customer service who is so reasonable if they are wrong is probably the same attitude when they really eat problems. Life is more important," Su Meili said.

　　"Ranking" into decoration

　　According to Li Jiang, director of the food market supervision department of the Beijing Municipal Food and Drug Administration, "among the 225 stores that were taken offline this time, in addition to unlicensed stores, there are also some stores that appear to have licenses but actually use other people’s licenses or forge licenses."

　　Among the 225 stores that were offline, including such restaurants: Wangshunge (Fortune Center Store), Milk Tea Marrying Powder (Jiaomen East Store), etc. were offline on the "Ele.me" platform; Ikeda Sushi (Longde Plaza Store), Yang Guofu Malatang (Beijing Xiaoyueyuan Store), etc. were offline on the Meituan takeaway platform; Shrimp Eating Shrimp Shabu (Liuliqiao Store), Mali Mala Fragrant Pot Grilled Fish (Guoao Store), etc. were offline on the Baidu takeaway platform.

　　"When I first ordered takeout, I looked for those with high sales and rankings, or even the top 10, but later found that it was not the same thing at all. Some takeout was produced by small workshops, and it was impossible to match the evaluation and sales." Liu Changsheng said that later, he chose takeout from more famous restaurants, "but it was still’hit ‘."

　　"Don’t believe those so-called rankings, popularity, and even user reviews. Most of them are artificial propaganda. They have nothing to do with the quality of the merchant’s food. When it’s time to have diarrhea, you won’t show mercy… In addition to using this information to fool people and induce users to place orders, there is no guarantee about the safety of their food, so that complaints are just a decoration." Cui Yonghua, who just resigned from a food delivery platform at the beginning of this year, said. "Many times, the platform only focuses on marketing strategies, but forgets that the most important thing for a company is the product and service."

　　In addition, according to Cui Yonghua, it has been exposed in the past that there are many "ghost restaurants" on some takeaway platforms, which means that merchants share addresses or share business licenses and health permits. "Those who do business development work in takeaway platform companies have to refresh new stores for performance, which makes there are many’zombie stores’ on the platform, especially beverage stores and dessert stores, which actually do not place orders at all."

　　"Brushing’zombie stores’ has performance, and everyone can earn a little more. Although I know that brushing orders is wrong, I feel that this is the normal situation of the industry after a long time, and it is understandable. The most torturous thing every time I rush the performance is whether to refresh the store. I know that brushing new stores will not make the business develop at all, but I still place orders for a little salary." Cui Yonghua said that the takeaway platform he once worked for has been promoting a business plan. Merchants can choose to go online voluntarily and charge a 5% commission as a technical service fee. There is no fee for not going online. "But the difference between going online and not going online is too big. Merchants who go online can get good rankings and positions, and merchants who don’t go online are ranked very low. For example, the ranking of the merchants I did not push online is basically after the mobile end is ranked ten screens, and they will not be seen by consumers at all. "

　　Liu Changsheng said that if takeout really cannot be effectively managed, there is no other way but to eat less or even no takeout in the future. "No matter how popular it seems, people can only avoid it. After all, there are many bad businesses, and more people simplify the food processing process for profit, but health is their own."

　　Takeaway delivery problem

　　No other way is not the best way. In addition to the merchants on the takeaway platform, diners are also finding another way.

　　Liu Changsheng once considered buying independent brands of takeout, "because of independent production and delivery, I think they should still be trustworthy, but recently I found a batch of such independent merchants’dead ‘."

　　The "independent brands" that Liu Changsheng refers to are those that promote their own kitchens or even central kitchens and can be delivered independently. Around 2015, this kind of takeaway to solve the problem of white-collar lunch took off.

　　Sun Tianqi, a former bank executive, was in this batch of "going to the sea", but his store only operated until the end of 2016.

　　Due to the central kitchen, Sun Tianqi can also order meals through WeChat and deliver them by himself. The average daily sales of Sun Tianqi’s box lunches are nearly 30 boxes, but the average daily sales of 100 boxes is far from the break-even point.

　　"The main reason is that the market has not yet opened," Sun Tianqi recalls, even if the customer base is increased, "but because the price of 25 yuan per serving is high for some people, the customer repurchase rate is high but the purchase frequency is low, even if you think the product is good, you can’t eat it every day."

　　The biggest barrier for "independent brands" compared with price is delivery.

　　Sun Tianqi is targeting the daily lunch market for office crowds, and the delivery time is highly concentrated. "We usually complete the meal packaging before 10:40 to 11:00, and stop receiving orders at 11:00 to formulate delivery tasks." Sun Tianqi said that the team includes three chefs, one customer service, plus me, a total of five people. "In the case of more than 30 packed lunches per day, due to the scattered orders, it is already full of staff."

　　If we continue to expand the scope of publicity and spread the distribution range from a 1-kilometer radius to a 3-kilometer radius, Sun Tianqi alone will definitely not be able to keep up with the logistics distribution.

　　"Due to the cost, I didn’t plan to build my own logistics, so I chose the takeaway platform." Sun Tianqi said that he had never wanted to go to the platform, mainly because there were too many management fee deductions. "To put it bluntly, these are all pure profits, which directly leads to the improvement of my profit and loss balance point. I have to reach an average of 125 copies per day to not lose money. But the platform has its own promotion attribute bonus and can solve the logistics and distribution problem, so in order to solve the main contradiction, I decided to go to the platform."

　　After contacting the delivery platform, Sun Tianqi could only describe his experience as "desperate":

　　The special delivery service of some platforms has restrictions on the delivery range, that is, within 3 kilometers, but Sun Tianqi’s target market is five or six kilometers, which cannot be delivered at all;

　　It is outsourced by the takeaway platform, but the outsourced rider is a part-time job, and there is no requirement to force the order. If the customer places an order but there is no outsourced rider to take the order, he will either deliver it himself or refund the order.

　　Sun Tianqi has also tried to communicate with the takeaway platform to expand the scope of special delivery, but the freight will also increase. Considering that the freight of 25 yuan products to the target market is about 5 yuan, if Sun Tianqi subsidizes the freight and deducts the management fee, there is almost no profit; if the customer bears the freight, the product price is even less competitive.

　　"If the distribution problem is not solved, it cannot be fully promoted, and the existing sales volume and potential market are far from enough to reach break-even, and the whole operation has entered a vicious circle." Sun Tianqi said, and finally chose to stop and suspend business.

Hu Ge

On November 7, the film "Hello, Zhihua", which was produced by Chen Kexin and directed by Shunji Iwai and starred Zhou Xun, Qin Hao, Hu Ge, Du Jiang, Tan Zhuo and others, held its world premiere in Beijing. All the creators appeared to promote the film. Hu Ge, who had not been seen for a long time, caused the audience to scream as soon as he appeared.

When greeting everyone at the beginning, Hu Ge said mischievously: "Hello everyone, I’m the one who owes the flat." The audience laughed.

Hu Ge

After that, a fan interacted with Hu Ge and said: "I want to pull him out and beat him up after watching it," Hu Ge jokingly replied: "I don’t know if my understanding is correct, this is a kind of praise for me." When it came to why he decided to participate in this role, Hu Ge admitted that he was the first fan of the director and did not want to miss this opportunity. In addition, he also thought that this role was very challenging and had a lot of space, which made him have a lot of impulses and a lot of creative desire.

　　On March 12th, Weibo’s topic "millet SU7 price" rushed to the first place in the hot search list of Weibo.

　　Under this topic, many netizens expressed their views on the pricing of Xiaomi SU7. Some netizens said that the pricing of SU7 would take the cost-effective route of Xiaomi, and it would be very conscience to price Xiaomi in the same configuration.

　　Previously, Lei Jun, the founder of Xiaomi, said that Xiaomi SU7 was designed according to the DreamCar standard, and the investment was very large, so it was a bit expensive, but it made sense.

　　Lei Jun also dismissed the rumored price of 199,000 yuan on the Internet, saying that the prices of 9.9W, 15.9W and 19.9W were all "joking".

　　It is reported that the length, width and height of Xiaomi SU7 are 4997/1963/1440mm, the wheelbase is 3000mm, and the drag coefficient of the whole vehicle is 0.195Cd, which is very excellent.

　　In the car configuration, the SU7 is based on the concept of Xiaomi’s car owner, equipped with Qualcomm Snapdragon 8295 chip and Xiaomi’s surging OS, with a 16.1-inch screen, providing 3K resolution and supporting CarPlay and AirPlay.

　　In addition, the SU7 will be equipped with a reversible dashboard and HUD head-up display, and the rear row will support the mounting of Xiaomi tablet for expansion.

　　According to industry insiders, Xiaomi SU7 has achieved three major ecological empowerment, integrating Xiaomi application ecology, hardware ecology and Xiaomi CarIoT ecology open to third parties, bringing a smart space experience.

　　On the evening of October 9th, Beijing time, the Royal Swedish Academy of Sciences announced that the 2019 Nobel Prize in Chemistry was awarded to Goodenough, a professor at the University of Texas at Austin, Whittingham, a professor at the State University of New York at Binghamton, and Akio Yoshino, a Japanese chemist, in recognition of their contributions in the field of lithium-ion batteries.

　　The three will share the prize of 9 million Swedish kronor (about 6.47 million yuan) equally. The Nobel Committee commented that "they created a rechargeable world".

　　It is worth mentioning that Goodenough, born in 1922, is 97 years old this year. This award has also set a new age record for the Nobel Prize.

　　Lithium batteries have completely changed life.

　　Li-ion battery research, which has been "running with you" for many years, finally won the Nobel Prize in chemistry this year.

　　After this year’s awards were awarded, the academic circles have said that the three scholars won the awards as "widely expected". Jiang Xuefeng, a professor at the School of Chemistry and Molecular Engineering of East China Normal University, commented that the three Nobel Prize winners played an important role in the basic model construction and industrial promotion of lithium-ion batteries.

　　The Nobel Committee commented that lithium-ion batteries have completely changed our lives since they first entered the market in 1991. Today, mobile phones, cameras and even electric cars, as well as pacemakers, etc., the most important energy source is lithium-ion batteries.

　　In addition, lithium-ion batteries are widely used to store other renewable energy sources, such as solar energy and wind energy, thus effectively reducing greenhouse gas emissions.

　　Lithium-ion battery is a kind of secondary battery, also known as rechargeable battery. Inside the battery, lithium ions (charged atoms) move along the path between two electrodes, thus generating current.

　　"Lithium atom has a unique property, its outer layer has only one electron, which is very easy to lose. Lithium batteries use the property that lithium atoms are easy to lose electrons, so that electrons can be transmitted on external wires and power equipment that needs electricity. " Jiang Xuefeng interprets the principle of lithium batteries.

　　Jiang Xuefeng introduced that if the battery wants to be recycled, it needs to turn the gain and loss of electrons into a reversible process, which requires selecting the anode and cathode materials of the battery. "It can be seen that three scientists have been using different materials to solve such problems in the development of lithium batteries."

　　The design foundation of today’s lithium-ion batteries was laid during the oil crisis in the 1970s. At that time, Whittingham, who worked for Exxon, an energy company, drafted the initial design scheme of lithium battery, using titanium sulfide as cathode material and metallic lithium as anode material, and made the first new lithium battery.

　　Ramster Romm, a member of the Nobel Prize Committee and a professor of chemistry at Linnaeus University in Sweden, introduced at the press conference that the potential of lithium metal batteries in Whittingham reached 2V. "The alkaline battery we use today is only 1.5V, so in terms of potential, this battery is quite good." Ramster Roma said.

　　In 1980, another Nobel Prize winner, Goodenough, discovered that lithium cobaltate could be used as cathode material for lithium ion batteries. The potential of this material is higher, reaching 4V— — As stated in the award speech, "the potential of the lithium battery has doubled".

　　Up to now, lithium cobaltate is still the most widely used cathode material for lithium ion batteries. Moreover, Goodenough also developed Ferrous lithium phosphate and other new lithium battery materials, and he was also honored as "the father of lithium batteries".

　　Solve the security problem and officially enter the business.

　　Lithium is a very active element. In order to avoid reacting with air, pure lithium is usually kept in oil. This also means that there will be safety hazards when lithium metal is used in batteries; In Whittingham’s early experiments, battery short-circuit explosion is common. This is one of the reasons why the above lithium battery can’t get out of the laboratory.

　　Scientists have been looking for ways to tame lithium.

　　In the 1980s, Japan’s consumer electronics industry was developed, so there was an urgent need for a lightweight and rechargeable battery to power camcorders, wireless phones and mobile computers.

　　Akira Yoshino, a chemical engineer working for Asahi Kasei Company, tried to find a safe and commercially available lithium-ion battery from Goodenough’s research. According to Goodenough’s theoretical model, he used lithium cobaltate as cathode and tried to use various carbon-based materials as anode. Yoshino Akira was very careful when testing the safety of the battery, and even put the testing work in a room dedicated to explosives inspection.

　　In 1985, Akira Yoshino replaced the reactive lithium in the anode with petroleum coke, a carbon-based material, thus completely eliminating metallic lithium and completing the world’s first commercialized lithium-containing alkaline lithium-ion battery.

　　Solved the safety problem, which means the arrival of the commercial era of lithium batteries. This new type of safe lithium-ion battery is favored by Sony. In 1991, Sony and Asahi Kasei released the world’s first commercial lithium-ion battery, which opened the "lithium-ion battery revolution" of consumer electronics products.

　　The Nobel Committee commented that this "lightweight and durable battery can be recharged hundreds of times before its performance declines". (Nanfang Daily reporter in Beijing Wang Shizhen Planning: Zhang Zhichao)
