On April 1st, the first day of commercial operation of Jinan Rail Transit Line 1, many citizens encountered many problems when taking the subway to "try early". On the afternoon of the 2 nd, the relevant person in charge of Jinan Rail Transit Group explained the eight major problems reflected by the public.

　　1. Face recognition can’t be brushed? It has been suggested to the public to send clear photos for system optimization.

　　"Brush your face" through the security check sounds very "tall", and many citizens have uploaded photo information early, just waiting for "brush your face and try it early" when taking the bus. However, some citizens have encountered the problem that "brushing their faces" cannot be recognized.

　　It is understood that the subway ticketing system of Jinan Rail Transit Line 1 is the first in the national subway. For the problem that citizens can’t accurately identify their faces when they brush their faces, the staff analyzed that, first, the system photos were uploaded by users themselves, and the input effect was different; Second, the recognition system is influenced by the environment and brightness; Third, the height and thinness of the citizens and the location of the distance recognizer have an impact on the recognition effect.

　　In response to this problem, the relevant person in charge of Jinan Rail Transit Group said that technicians have been instructed to optimize the face recognition modules in a targeted system, and at the same time, the surrounding environment and illumination of each face recognition module are analyzed again. "The face recognition system also has self-learning technology. With the gradual learning and improvement, the recognition speed and accuracy will be improved. At the same time, it is also recommended that the public upload clear photos and try not to upload outdoor photos or backlight photos. "

　　2. The bus card can’t be recognized? Some old cards have security vulnerabilities, so it is recommended to replace them with new cards.

　　During the operation of Line 1, some citizens who came to the bus with bus cards were stopped in front of the gates because of "invalid cards".

　　According to staff statistics, bus cards with problems are divided into two categories. First, activity cards including spring and autumn cards and green travel cards; The second is to issue older cards and bus cards.

　　The person in charge of Jinan Rail Transit said that the bus activity card had been notified before and could not be used when taking the subway. The older cards and bus cards were issued earlier because of the long time span and security loopholes. "Including buses, they are gradually replacing old cards with security loopholes. You can replace new cards at bus service outlets for free or apply for Quancheng Pass at subway stations." Among them, Quancheng Tongka can enjoy a 20% discount, but there are no free rides or other preferential activities.

　　3. Brush the QR code and allow it in and out? Confusion of multiple payment methods will optimize the APP interface.

　　On the first day of the bus ride, some citizens also encountered the problem of brushing the QR code into the station but unable to leave the station.

　　According to the person in charge of Jinan Rail Transit, after the statistics of the first day, most of the abnormal users used QR codes to enter and leave the station, which was mainly caused by the mixed QR codes of one-way tickets and stored-value tickets on the APP. "It is possible to brush the QR code of a one-way ticket when entering the station, and turn off the APP during the ride. Because the options of one-way ticket and stored-value ticket are close, the QR code of stored-value ticket was mistakenly selected when leaving the station, resulting in the inability to leave the station without pit stop information. " In this regard, they will optimize the interface when the subsequent version of Jinan Metro APP is updated. "The QR code of the stored value ticket is left on the home page, and the one-way ticket is placed on the secondary interface to strengthen the distinction." Among them, citizens can enjoy a 20% discount by brushing the QR code of stored value tickets, but there is no discount for one-way tickets.

　　4. What about the elderly and the disabled? Blind people can enter the station with a disabled card, and guide dogs can also enter the station.

　　The person in charge of Jinan Rail Transit said that according to relevant regulations, elderly people aged 60 to 64 can enjoy half-price concessions, and elderly people aged 65 and over can enjoy free rides. "If the old card can’t be brushed, you can arrange to take the green channel. It is recommended to replace the new card in time next time."

　　Disabled people who take the subway can enter and leave the station directly through the gate with their love cards, while blind people can enter the station directly with their disability cards and ride for free. Staff will be arranged at the entrance and exit of each station of Jinan Rail Transit Line 1 to help the blind. "Guide dogs can also enter the station". In addition, all stations are equipped with wheelchairs and wheelchair pedals to provide passengers in need.

　　5. The subway APP can’t be used? Users are advised to uninstall the ticketing version in time and download the latest version.

　　During the trial operation, Jinan Rail Transit launched the "Grab Ticket APP" to provide experience services for citizens who want to "try early". Since March 20, the APP has stopped serving. On the first day of operation on April 1, some unsuspecting users encountered obstacles when using the "grab ticket version APP".

　　In this regard, the relevant person in charge of Jinan Rail Transit said that the Jinan Metro APP has been downloaded simultaneously in Android and Apple, and the test version that originally included the ticket-grabbing activities for the visit has stopped serving. "Please ask the public to uninstall the ticket-grabbing version of the APP in time and download and install the latest version in the application market. Jinan Metro APP".

　　6. The ticket vending machine can’t buy tickets in cash? Only cash can be bought by the staff.

　　The person in charge of Jinan Rail Transit said that with the development of mobile payment technology, the amount of cash tickets purchased is getting less and less. Some cities have gradually cancelled the cash ticket purchasing function of automatic ticket vending machines, and gradually reduced the number of automatic ticket vending machines. At the beginning of the operation of Jinan Rail Transit Line 1, considering that most passengers are used to the convenience brought by mobile payment technology, Jinan Metro encourages passengers to use WeChat or Alipay to purchase tickets at automatic ticket vending machines. For passengers who really only have cash but can’t purchase tickets through WeChat or Alipay, they can pay the cash for the tickets to the on-site staff, and the staff will purchase tickets for the passengers through the ticket vending machine.

　　7. How to get an invoice for non-cash ticket purchase? Each station customer service center can receive an APP to provide electronic invoices.

　　The relevant person in charge of Jinan Rail Transit said that at present, citizens will provide invoices when purchasing tickets in cash at the customer service centers of all stations across the line. For citizens who use one-way tickets, bus cards and Quancheng Pass cards, they can collect invoices from the station customer service center with valid tickets.

　　For citizens who use the QR code and face brushing functions in Jinan Metro APP, they can use the "Electronic Invoice" function in the "Personal Center" interface of Jinan Metro APP to receive electronic invoices according to the prompt process.

　　8. How can I get a refund? If the ticket is not in the station, the refund will be automatically returned.

　　For the users who did not take the physical ticket or did not scan the code to enter the station for various reasons after purchasing the ticket, the person in charge of Jinan Rail Transit said that such users can apply for a refund in Jinan Metro APP, and the ticket will be "received in seconds" and returned to the personal balance. "If I forget to return the ticket, the system will automatically refund the ticket at 24: 00 on the same day, and the ticket will be returned to the balance of my personal account."

　　For users who have swiped a one-way ticket into the station but temporarily left the station at the intermediate site, the refund service cannot be provided. "When you leave the station, the one-way ticket has been automatically recycled, so you can’t refund it."

　　Kunming, August 26 (Xinhua) The reporter learned from the Forest Public Security Bureau of Jingdong County, Yunnan Province that a national second-class protected wild animal, the Chinese gazelle, recently broke into the homes of local farmers, and the farmers called the forest public security bureau for help.

　　On the 22nd, a "monster" suddenly broke into the home of a villager in Wenjing Town, Jingdong County. Its horns were like antlers, the head of a sheep, the hoof was like a cow’s hoof, and the tail was like a donkey’s tail, which was a realistic version of the "four unlike".

　　It strayed into the pigsty after a while in the yard. The villagers quickly shut it up and called the local forest public security bureau for help the next day.

　　The police of the Forest Public Security Bureau of Jingdong County rushed to the villagers’ homes. After careful identification, it was confirmed that the monster that broke into the farmhouse was named Chinese gazelle, which belongs to the national second-class protected wild animal. The police analyzed that it may be due to the heavy rain in the local area. After walking out of the nearby forest, the Chinese gazelle mistakenly broke into the villagers’ homes.

　　It is understood that the Chinese gazelle, also known as the Ming-bristle sheep, belongs to the family Bovidae and is a typical forest-dwelling animal. It is one of the typical animals in the tropical and subtropical regions of southeast Asia, and mainly lives in mixed coniferous and broadleaved forests, coniferous forests or rocky miscellaneous shrub forests at an altitude of 1,000-4,400 meters.

　　After careful examination, the police did not find that this Chinese gazelle was injured and aggressive, so it was judged that it had the ability to survive in the wild and was suitable for being released into nature. Subsequently, the police took this Chinese gazelle to a suitable location in the wild and released it to nature. (Miao Chao Zhou Wei)

　　That song "Have money and no money to go home for the New Year" has sung the voices of countless homecoming people.

　　All the way to the dusty, tired, as long as the plunge into the hot "home", a year of hard work is worth it.

　　But I don’t know when, the family reunion has changed its taste, adding a touch of awkwardness of being close to home.

　　Lin Yutang said: "Chinese’s face can not only be washed, but also thrown away, rewarded, contested and kept. Sometimes it seems that fighting for face is the first meaning of life."

　　The more people there are, the more you can’t escape the absurdity of "saving face"

　　01

　　How many people were kidnapped by face during the Spring Festival?

　　Face, the first meaning of visiting relatives and friends during the Chinese New Year.

　　In order to be "decent", it’s painful to punch a swollen face and fill a fat man.

　　1. You are a mature adult. It’s time to learn to pay a good New Year call.

　　The pain of being forced to show "communication skills" is comparable to talent show.

　　No matter how close you are to each other or how deep your friendship is, you have to smile, say hello warmly and take the initiative to greet each other, even if you don’t know the relationship at all.

　　Anyway, pull my parents’ sleeves, smiling mother immediately prompt:

　　This is the second cousin of your third uncle, Grandma Wang, and we are close relatives. According to your seniority, you have to call someone an old aunt!

　　Then, you have to hide your embarrassment with a smile and pretend to be caring and attentive naturally.

　　The days of visiting relatives can be described as the peak period of social phobia patients.

　　In the eyes of many parents, if you can’t greet your relatives and friends warmly, you are guilty of a big taboo, because "giving others a face is giving yourself a face."

　　In Family with Children, Liu Xing’s good friend Mouse went to Liu Xing’s house with her mother.

　　Mother winked and poked at her son. Every time she poked, the mouse said a compliment with a grin on her face.

　　Mouse and Mom/Family with Children

　　Xia Donghai and Liu Mei also had to follow closely, returning an anodyne greeting.

　　Liu Mei and Xia Donghai/Family with Children

　　After several rounds of "full chat", the mother was still not satisfied, poked her son again, and muttered with a mouse:

　　Mouse and Mom/Family with Children

　　The same is true for holidays. I have been struggling for 358 days in complicated social relationships. I finally have 7 days to stay at home and raise my spirit to be "willful", but I still have to deal with the world.

　　A superficial greeting, the same courtesy, the greeting person is exhausted physically and mentally, and the person being greeted is also embarrassed.

　　Liu Xing and Xia Xue/Family with Children

　　In the end, whose dignity was fulfilled?

　　2. "How drunk you can drink means how much you can afford me."

　　Distant relatives I haven’t seen for many years, old classmates I haven’t gathered together for a long time …

　　Common topics are becoming less and less, and the exchange of feelings depends on a glass of wine.

　　Drinking is supposed to be fun, but there are always people who, in order to highlight their appeal, turn drinking into a "mutual test" to keep up appearances and gain prestige.

　　"If you don’t drink, you won’t give me face."

　　"You are embarrassing me."

　　After three rounds of drinking, toasting becomes persuading, and persuading becomes forcing.

　　No one wants to be labeled as "indifferent to feelings" and can only surrender under the coercion of "deep feelings and a stuffy mouth"

　　Drinking a few glasses of wine has become a sign of testing the depth of friendship, which only satisfies the vanity of the drinker.

　　In the eyes of many people, drinking is related to their own face. Not drinking is almost linked to "incompetence", and refusing to drink means "not being brothers enough".

　　In order to be a hero, talk about loyalty, and fight for wine without restraint, it is more than human feelings that are kidnapped.

　　Mr. Shi, 40, dined with his comrades-in-arms for many years.

　　Mr. Shi, who was weak in alcohol, was embarrassed to be a wet blanket and forced himself to drink six bottles of beer.

　　During the dinner, he couldn’t help but want to go to the bathroom to vomit, and he was afraid of being laughed at. As soon as the dirt in his stomach swelled up, he held his breath hard and pressed it back.

　　Finally, Mr. Shi’s abdominal pain was unbearable, and he fell down on the table. After being sent to the hospital for examination, he found that Mr. Shi’s esophagus was "exploded" by the gas of beer.

　　If you want to save face to a certain extent, even "living a life of suffering" is a luxury.

　　At a dinner party in Jinhua, Zhejiang, 10 people advised each other to drink, and one of them was lying in the lobby of the hotel to sleep because of lack of alcohol.

　　By the time everyone came back, he was out of breath.

　　The police introduced Mr. Shi’s misfortune due to excessive drinking/pear video

　　The other nine people who drank at the same table were found to need to pay more than 600,000 yuan to the families of the deceased because they failed to fulfill their dissuasion obligations and failed to send their drunken friends home.

　　For the sake of the so-called face, punching a swollen face and filling it with fat, breaking a tooth and swallowing it in the stomach, at most, it is a temporary pain.

　　If you bet your life and put your health in it, it is really too late to regret it.

　　3. Even if you overdraw, you have to have a "decent year"

　　What are you most afraid of when you go home during the Spring Festival?

　　Endless marriage, birth, comparison and entertainment …

　　At the end of the day, I am most afraid of meeting that "you are so bad" look.

　　People who have worked hard outside for a year return to their hometown with great joy, only to find that the taste of the year is getting weaker and weaker and the taste of money is getting heavier and heavier.

　　A few days ago, there was a hot search on the national lucky money map.

　　Red envelopes of several hundred yuan are normal, but in some places, lucky money has already reached tens of thousands.

　　National Lucky Money Map/Weibo @ Sina News

　　China News Network once made a statistic, how much does it cost to spend a decent year?

　　The result is very heartfelt, and it costs 8900~36000 yuan.

　　Spring Festival spending statistics/China News Network

　　No matter how the year goes, you should at least "pretend" to be decent, so as not to be looked down upon.

　　If you can’t return home with clothes on, you should also "rent" it.

　　Ms. Liu, a white-collar worker in Shanghai, rented a 20,000-yuan bag to go back to her hometown this year. "There are many classmates and family gatherings to attend, and I need a decent bag."

　　The person in charge of the operation of a rental platform revealed, "In the first half of the month, the booking demand of some luxury brands began to rise sharply, but because many users will directly renew their leases, many users have not rented them."

　　It is understandable to show your success and pursue decency. If you deliberately show off, it will change its taste.

　　Netizens lamented the excessive pursuit of decency and the taste of the New Year/Weibo

　　People who really care about you, whether you get ahead or not, will leave a pair of bowls and chopsticks for you to have a hot meal with.

　　Too much care about other people’s eyes, trouble and money to cover up, but failed to live up to this hard-won reunion.

　　02

　　The face piled up by matter is doomed to be fragile.

　　In his autobiography "My First Half Life", Puyi once recalled the luxurious imperial life.

　　Even the daily thing of eating, the royal family can toss out a huge set of ostentation and extravagance, and decorate the decency to the extreme.

　　"The biggest ostentation and extravagance that consumes manpower, material resources and financial resources is eating.

　　I ordered a’ pass the meal!’

　　The little eunuch in front of him said the same thing to the eunuch in the temple on the Ming Temple in hall of mental cultivation,’ Pass the food!’

　　The eunuch in the temple passed this on to the eunuch standing outside Yangxin Gate, and he passed it on to the eunuch waiting in the imperial kitchen in West Strip … So it has been passed into the imperial kitchen.

　　Before the echo disappeared, a procession like a dowry had walked out of the imperial kitchen.

　　This is a team composed of dozens of eunuchs dressed neatly, carrying seven dining tables, holding dozens of red lacquer boxes painted with golden dragons, and heading straight for hall of mental cultivation. "

　　These dishes are just a formality. I don’t know how many times they have been reheated in order to complete the above process.

　　Puyi doesn’t eat these things, but wastes them in vain.

　　Confucius’ phrase "Never tire of eating fine food, never tire of eating fine food" originally emphasized the etiquette of life, but it has changed from generation to generation.

　　The culture of advocating etiquette and norms has created Chinese’s unique face view.

　　The royal family has its own strength to show off its prestige, while ordinary people pretend to be "face-to-face" for the sake of others’ eyes, so they can only eat their own bitter fruit.

　　Some scholars put forward the concept of "status consumption", which means that consumers convey their social status to others and improve their image through conspicuous consumption.

　　In short, it is to spend money to buy face.

　　According to the American magazine Jing Daily, by 2025, the luxury goods purchased by China’s post-90s and post-00s consumers are expected to account for 46% of the global market.

　　At the same time, the debt-to-income ratio of the post-90s generation in China reached an astonishing 1850%.

　　Behind the prosperity of luxury consumption, there is a worrying debt risk.

　　China tourists buy luxury goods/vision china.

　　Mr. Shen Lao, who lives in Shanghai, has a history of uremia for many years and relies on drug treatment to maintain his life.

　　Over half a year old, but I owe 1 million foreign debts.

　　This debt is owed by the adopted daughter.

　　Before that, he had paid off more than 1.3 million debts for his adopted daughter, patched things together and ran around …

　　Shen Lao’s self-report on bitter family affairs/"Case Focus"

　　In July 2017, Mr. Shen Lao’s adopted daughter suddenly disappeared, leaving a "suicide note" that listed all the foreign debts he owed.

　　"suicide note"/"case focus" left by adopted daughter

　　Mr. Shen Lao can’t believe it. The adopted daughter is a kindergarten teacher. How can she spend so much money?

　　According to a friend, Miss Shen spends a lot of money and is keen on buying brand-name clothes, cosmetics and bags.

　　My friend said that Miss Shen loves luxury bags/Case Focus.

　　When I first borrowed money, I just wanted to change my computer.

　　I tasted the sweetness of "decency" and gradually indulged in luxury goods that did not match my income, which gradually ruined a stable life.

　　In "Super Speaker", player Zhang Xiaolei has a thought-provoking passage:

　　Face is the most precious luxury in the world. How many people let go of their own limits and principles for it? They should take care of others’ faces and observe others’ glances.

　　You can build a decent face with materials, but after all, it is still a mirror, deceiving yourself.

　　03

　　Focus on the "lining"

　　Face is as funny as it looks noble.

　　Dou Wen Tao, the host, once filled a venue for the "buddy".

　　Many years ago, an unknown young man went through several layers of relationships and found Dou Wen Tao to help him marry.

　　Dou Wen Tao recalled helping to preside over the wedding/"Round Table"

　　The wedding scene was quite spectacular, and all the local dignitaries were present.

　　Dou Wen Tao also "played enough" and didn’t give a clue.

　　After the banquet, the groom confided to Dou Wen Tao: "This wedding is fake, it is for parents."

　　It turned out that the bride and groom had no intention of getting married.

　　The whole day’s fleet scheduling and luxury brothers lineup are all to show the neighbors who once looked down on the groom’s family how prominent their family is.

　　The so-called wedding is actually a sad farce.

　　"Face this thing can’t be defined. It’s like honor, but it’s not like honor.

　　It can’t be bought with money, it can give men or women substantial pride.

　　It is empty, men fight for it, and many women die for it. It is invisible, but it can exist only by showing it to the public. "

　　Sociologist Erving·Goffman’s parody theory reveals the essence of face: it is the social position or prestige that an individual obtains in society.

　　What many people can’t see through is that a person’s social status and external evaluation do not depend on the external appearance, but on the internal quality that a person has.

　　The evaluation standard of the world is always determined by value, and it is by no means a secular vision.

　　How much weight you have, how much face others will sell you.

　　Calm down and think about it, and you will find that 99% of what happens to yourself every day is meaningless to others.

　　There’s a line in The Master:

　　People live a lifetime, some people become face, some people become lining.

　　"If you don’t return to your hometown with wealth, you will never know." The overlord of the place of Xi Chu, who knows how to save face, will also be ridiculed as "dressed like a monkey."

　　Face is the facade to decorate the lining. As long as it is the facade, it may collapse in an instant.

　　As a "lining", the inner cultivation and personal qualities are invisible and intangible, but they really support a person’s solid spine.

A new invention: thermal liquid sensor was tested and verified in Chentian laboratory.

　　During the awarding ceremony of the 2017 Qiu Chengtong Science Prize, I talked with Professor Yao Qizhi, an academician of the Chinese Academy of Sciences, an academician of the American Academy of Sciences and a Turing Prize winner.

　　On the eve of the Spring Festival, Li Chentian, a 17-year-old high school student from Zhuhai, went to the United States at the invitation of Tsinghua University to participate in the "Global Innovation Experience Camp" jointly organized by Tsinghua and Washington University. He won the best project award in this innovation challenge by virtue of the "active high-voltage power line deicing monitoring system" invented on the spot. Later, he flew back to Beijing, as a participant in the last ISEF (International Science and Engineering Grand Prix), and introduced his experience to the young people who were participating in the 2018 ISEF project selection and international exchange winter camp.

　　He invented the fluorine-free electronic refrigerator at the age of 9, the solar intelligent outdoor manhole cover management system at the age of 12, and the programmable terminal and operating system at the age of 13. So far, he has nine national invention patents … What kind of "awesome person" is Li Chentian? Why have you achieved so much at such a young age? The all-media reporter of Guangzhou Daily takes you to know the young man who is praised by the outside world as "Edison" in China.

　　At the age of 5, I designed light-controlled lanterns for myself.

　　Last weekend, when the reporter saw Jerry Lee Tianshi, he wore an old school uniform and black-rimmed glasses, which was very low-key; He was a little shy when he didn’t talk, but when he started talking about his invention, Li Chentian hardly stopped for more than two hours, and he spoke as fast as a machine gun. When I met some professional terms, I was a little confused when I watched the reporter. He kept changing his body movements to explain it.

　　Li Chentian’s family said that his whimsy began in childhood. My father said that he showed a strong interest in electricity when he was learning English in the early morning. Every time he was carried out by his mother and saw the neon lights flashing on the street, he would dance. "How can anyone be on the TV?" "How can a toy car automatically turn?" ….. Since I was two years old, I have often asked my parents who are all from liberal arts to be speechless.

　　Because of her strong interest in electronic products, at the age of five, Chen Tian borrowed her cousin’s middle school physics textbook for self-study. On the Spring Festival that year, the family was going back to their hometown. Before leaving, they were worried that the red lanterns hanging on the balcony of Zhuhai’s home were left unattended in the morning. They had been on for more than ten days, which was both a waste of electricity and a fear of causing safety accidents. He sprouted the idea of designing a light-controlled switch. "It will automatically turn off the lights when there is sunshine during the day and turn on the lights at night when there is no sunshine." As a result, he removed a sensitive relay from a radio through two days of fiddling, and really made such a switch through transformation.

　　However, in the eyes of Chen Tian, the first real invention was the "fluorine-free electronic refrigerator" he built when he was 9 years old. Later, he was out of control. At the age of 12, he invented the "solar intelligent outdoor manhole cover management system", and at the age of 13, he developed the "programmable cloud-and-thing terminal and operating system" … At the age of 12, he won the first prize in the Guangdong Youth Science and Technology Innovation Competition for six consecutive years and won the national first prize three times. At the end of last year, Chentian won the Science Award and the Silver Award in Computer Science in the 2017 Qiu Chengtong Middle School Science Award Global Finals with his paper "Universal Power Adaptation Protocol (UPP) and Its Implementation". From provincial and municipal competitions to going abroad to represent China teenagers in ISEF, Li Chentian has won more than 30 scientific and technological innovation competitions, and has successfully applied for 9 national invention patents.

　　All whimsy comes from life.

　　"There is no epiphany in science. I just invested enough time in invention and creation. I just started the accumulation of’ 10,000 hours’ earlier." Li Chentian said modestly that to make inventions, we must first have a strong interest and then invest a lot of time.

　　Chen Tian said that you should be curious when making inventions and pay attention to everything that happens around you. All my whimsy comes from life. The idea of the project "Active High-voltage Power Line Deicing Monitoring System" when I participated in the Innovation Challenge in the United States originated from the ice disaster in 2008. He was deeply impressed by the embarrassing picture of manual mechanical deicing in the power sector on TV, so he always had an idea, "If the frozen wires can be deiced automatically, even the wires in the alpine zone can not be frozen!" Over the past few years, he has done a full technical demonstration for this project, and this global innovation experience camp just gave him such an opportunity. Chen Tian said, "Due to sufficient technology accumulation, the original prototype of this project took only two days, and finally won the highest award’ ‘Best Project Award’ in the participating projects."

　　The topic he is working on, "Variable Temperature and Pressure Pump", was inspired by his parents taking him skiing in Harbin during the winter vacation in 2016. At that time, he saw a small vendor barbecuing with liquefied gas on the street, and the fire went out. As a result, he saw the small vendor cover the gas bottle with a towel, pour some boiling water on the towel, and the fire "sprayed" again. He said that when he saw this phenomenon, he was very excited and thought that this phenomenon might solve the problem of transporting low-viscosity liquids such as refrigerants that he had always wanted to solve. If the pressure in the pump chamber is changed by changing the temperature instead of moving parts such as piston, wouldn’t it be possible to manufacture a pump without moving parts?

　　Parents support the "disruptive" behavior of disassembling and tampering with household appliances from an early age.

　　Chen Tian said, "If I make small achievements, I would like to thank my parents for their tolerance and support." Since childhood, his parents never forced him to attend interest classes, and he was not required to be a schoolmaster. He said that he has never attended any cram school since he went to school. During the holiday, he either stayed at home to make inventions or participated in scientific and technological competitions and exchanges in various places.

　　Parents also fully support the "disruptive" behavior of dismantling household appliances that they have shown since childhood. Just in the first grade of primary school, in order to study the temperature control switch, I dismantled a newly bought electric heating plate imported from Germany at home in the morning. At that time, the market price was more than 2,000 yuan. When he was 9 years old, he developed a fluorine-free electronic refrigerator. In order to buy a refrigerator, his parents took him to Beijing to find many shops, and finally spent three days scouring Zhongguancun for the desired products.

　　In order to support his son’s innovation and invention, his father set up a "morning lab" for him at home. In this laboratory, the reporter saw a laser positioning machine, a small supercomputer with 72 cores, a multifunctional calibration measuring instrument with data stability of 2ppm, a multifunctional vector network analyzer and a very advanced mixed-signal oscilloscope.

　　"Over the years, the equipment in this laboratory alone has invested more than one million yuan, not including thousands of old electronic products that he invents and buys every time and dismantles." Chen Tian’s father smiled and said, "If we only talk about the electronic laboratory, my laboratory may be the best in Zhuhai."

　　However, apart from scientific and technological inventions, Chen Tian has no other hobbies. As long as he doesn’t go out to participate in scientific and technological competitions and exchanges in his spare time, he basically stays in this laboratory.

　　Learning computer programming in the fifth grade of primary school is painful to cry.

　　Li Chentian does not agree with the reputation of the outside world as a "genius boy". His parents have repeatedly stressed that their children have only shown strong interest in electrical appliances and circuits since childhood, and they are ordinary teenagers. "He is only willing to spend time on electronics," my father said seriously. "Since I was a child, I love to disassemble things. Others sell old household appliances at home, and my family often buys them back from outside."

　　Chen Tian added that every design or invention is not always smooth sailing, and there are many failures. There are two or three thousand discarded circuit boards at home. And when learning theoretical knowledge, I once had the idea of giving up. With the deepening of scientific research, he had to learn computer programming for a project in the fifth grade of primary school. Most of the electronic components encountered before are concrete things, while computer assembly language is too abstract. For a child in the fifth grade of elementary school, it is like reading a gobbledygook at first. "If you don’t understand, you can’t learn!" Sometimes I read until late at night, and in the morning I said that I was so miserable that I cried and wanted to give up several times. Finally, with the encouragement of his father, he persisted, and it took him more than a month to write the first program-"digital clock". Looking at the success of the first string of code written by myself, Chentian jumped with excitement. "He was yelling, and then he ran downstairs from upstairs and kept shouting, Dad, I made it up." Dad recalled.

　　Text, map/wide newspaper all-media reporter Chen Zhijia

　　CCTV News:According to the website of the Central Meteorological Observatory, in the coming week, the atmospheric diffusion conditions and wet removal conditions in most parts of the country are good, and there is no large-scale haze weather.

　　The specific forecast is as follows:

　　Xing Tu Xing Ji Yuan ES is Chery’s flagship model, which uses Chery’s most advanced technology in all aspects. So what hard-core technology does Xing Ji Yuan ES have?

　　First of all, Xingyue ES comes from E0X high-performance electric platform, which is a brand-new platform built by Chery for the future of electrification. Now, building a car is nothing more than two dimensions of intelligence and comfort, and so is E0X platform. E0X platform consists of two parts, one of which is a high-performance physical platform architecture, mainly around the aspects of battery, electric drive, driving control, safety and lightweight, and the other is a high-intelligence electronic and electrical architecture, mainly including high-computing hardware and software, secure communication and high-speed OTA.

　　Specific to Xingyue ES, the high-equipped models are based on the 800V high-voltage platform, and the charging, discharging and energy storage efficiency will be improved under the high-voltage platform. At the same time, the power devices are made of SiC silicon carbide materials, and the working efficiency will be higher.

　　Xingyue ES supports charging for 5 minutes and charging for 30% to 80% in 15 minutes, which can match 750V-1000V ordinary fast-charging piles and super-charging piles. At the same time, ES also has a 400V low-profile model, and the price is more acceptable. The battery supplier is Jiangsu Times, which is owned by Contemporary Amperex Technology Co., Limited. There are lithium ternary batteries and lithium ternary batteries mixed with Ferrous lithium phosphate. The battery capacity ranges from 60 to 97 degrees, the power consumption of CLTC is 11.7kWh/100km, and the battery life of CLTC ranges from 570 to 900 km.

　　E0X platform is Chery’s main platform for the future. Within two years, based on this platform, 15 pure electric vehicles will be launched, including cars, SUVs and MPVs.　

　　The second highlight of Xingyue ES is its pan-tilt chassis. The whole chassis system includes a series of air suspension, CDC shock absorption, brake by wire, intelligent torque distribution and lightweight materials. Suspension structure: front double ball joints, double wishbone and rear five links are made of a large number of all-aluminum materials, and the front suspension swing arm, front and rear knuckles, rear subframe and brake calipers are all made of all-aluminum. With air suspension +CDC vibration reduction, it means that the suspension height is adjustable, and the suspension damping can be adjusted in real time and actively through intelligent algorithm, and with other software and hardware, the suspension damping can be adjusted in advance.

　　In order to cooperate with the advanced driving assistance function in the later period, Xingyue ES is equipped with a brake-by-wire system, which has a fast braking response, improves the active braking performance, and allows the motor to recover the braking energy to the maximum extent. For the four-wheel drive version, the intelligent vector four-wheel drive technology can switch the power between two-wheel drive and four-wheel drive within 0.2s.

　　The chassis of Xingyue ES is almost full, which is a big killer. More than 200,000 people have air suspension, which was unthinkable before. Xingyue ES has pushed these configuration thresholds to a new low.

　　The third highlight is that Star Age ES is equipped with iFLYTEK Spark Cognitive Model for the first time. This model is mainly aimed at human-computer interaction and intelligent driving. Needless to say, human-computer interaction is nothing more than voice assistants, landing applications and localized services. In the intelligent driving part, the mid-and-low-equipped model of Star Age ES is equipped with Horizon Extended Range 3 chip, with 5 cameras, 8 ultrasonic radars and 2 millimeter-wave radars, which can realize L2-class driving assistance. The top model adopts two NVIDIA DRIVE Orin chips, with 12 cameras, 12 ultrasonic radars, 5 millimeter-wave radars and 1 laser radar. Due to the improvement of hardware and computing power, it supports high-speed and urban elevated roads, urban roads and parking lots, covering the whole scene, and can realize the functions of high-speed NOP, urban NOA and intelligent parking AVP.

　　　 On March 11, 2024, the new Porsche Taycan (parameters | inquiry) was launched globally at the Porsche Experience Center in Shanghai. The new car will be introduced into seven domestic models, including Turbo, Turbo GT, Turbo Cross Turismo, etc. It is planned to start pre-sale in mid-April. Although the appearance of the new Porsche Taycan has not changed much, the motor, chassis and other parts have been significantly improved, which can be said to be a first大规模中期改款。

　　虽然是中期改款车型，外观改动并不是非常大，但是机械层面的变化可是非常巨大。新款车型有下面三个特色：

　　● 更高：充电速度增加50kW，最高可达320kW。超过300kW的充电速度可持续长达5分钟，即使在低温下充电性能也不会受到太大影响。

　　● 较高车速的动能回收最高可达400kW（原为290kW），绝对不浪费一分能源！

　　● 更快：0-100km/h最多可提高0.6秒。Taycan Turbo S仅需2.4秒。

　　● 续航里程增加了35%，达到最大678km（WLTP）。所有Taycan车型均可在18分钟内将电池从10%充电至80%！

　　首先，新款Taycan Turbo GT在线上完成了首发，该车正是此前缔造纽北圈速7分07秒55原型车的量产版，该圈速比Taycan Turbo S快了26秒，相当于甩开了1.3km的距离。据悉，该车最大功率可达1108马力（815kW，超增压功率，持续2秒），峰值扭矩1340牛?米，极速可达305km/h，0-100km/h加速仅需2.2秒，在新型900A逆变器加持下，Attack Mode（进攻模式）还可在10秒钟内额外获得120kW的功率。

　　中期改款的保时捷Taycan依旧是我们熟悉的样子，不过在车头部分的细节还是有所变化。最大的不同在于采用了全新大灯组，同时新车大灯具备HD Matrix（高清矩阵）技术，灯组内部拥有超过32000个LED光源组成的像素阵列。这样的好处在于能够实时调整照明区域和亮度，做更精细的分区。例如夜间对向来车时，大灯能够关闭一部分LED像素来防止直射对方驾驶员的眼睛，或者是针对路标照明。而其远光灯的射程可超过600米。

　　In addition, the air inlet shape of the front face of the new car has also been adjusted, and the aerodynamic effect is even better. The new Taycan Cross Turismo has also been upgraded for configuration, including aluminum alloy roof rack, Sport Chrono components, passenger display, PASM dual-cavity air suspension, and sports car sound wave simulation, which are all called standard for the whole series.

　　The new models come standard with optimized, aerodynamic wheels and tires that reduce rolling resistance. The 21-inch wheels and tires were also redeveloped for the car, and officials say the new rims increase the range by up to 40 kilometers (under WLTP conditions).

　　The shape of the side and tail has not changed much. It is worth mentioning that the mid-term replacement Porsche Taycan has also made great efforts in lightweight, whether it is the body material or the motor, etc., the weight has been reduced, so the weight of the whole vehicle has been reduced by 15kg.

　　The interior can be said to be a highlight of this new car, but the shape has not changed significantly from before, and it is more reflected in the material, function and other aspects. Specifically, the mid-term replacement Taycan will provide a new two-color interior for consumers to choose from. The interior material adds a soft bag material for the door. Not only that, but wireless charging is also provided in the car.

　　In addition, the new car has been redesigned for the function display of the in-car instrument, which can display information such as the current charging power of the vehicle and the maximum power supply provided by the infrastructure. In terms of car-machine functions, Apple CarPlay + has been added for the car-machine interconnection. In addition, for the passenger display, a private viewing mode has been added.

　　In terms of safety configuration, the mid-term replacement Taycan has been upgraded for the assisted driving system, with standard configurations such as reversing images, lane change assistance, traffic congestion assistance, and 3D environment simulation display.

　　If frenetic tram acceleration doesn’t satisfy you, models with Sport Chrono components can add 70kW of power (depending on the model) by pressing the "Supercharge Mode" button for 10 seconds. On the Taycan Turbo S, it can add 140kW, increasing the output power to 700kW/952PS.

　　Equipped with a new rear axle motor, which generates 80kW more power than the previous model, an improved pulse inverter, software, a more powerful battery, improved thermal management, a next-generation heat pump, and an improved recovery and four-wheel drive strategy, the new Taycan is all different.

　　In addition, the chassis suspension is also a highlight of this car. All new Taycan models come standard with adaptive air suspension. The new Porsche Active Ride suspension is available as an optional package for the four-wheel drive version. It is equipped with the same chassis suspension system as the Porsche Panamera. From the previous three-chamber air suspension to the dual-chamber air suspension with dual-valve shock absorbers, it can achieve faster, more sensitive response speed and higher comfort.

Competitor: Tesla Model S Tri-Motor All-Wheel Drive Plaid Edition

　　As the "leader" of electric vehicles, Tesla has always been the target of everyone’s pursuit, even if it is a sports car family with a good pedigree like Porsche, it can’t help but be compared with Tesla. Accelerating and cracking, fast, is the first impression of Model S, although its control and Taycan can can’t be compared, but relying on the power of the miraculous rim law, it also has good results on the track. More space is its advantage, and in terms of power management, Tesla has always had its own unique.

● Conclusion

　　These enhancements make the new Taycan even more attractive. Although Porsche has not performed very well in the smart cabin smart driving function, few car manufacturers can compare it in terms of driving. Although the price of the new car has become higher, but various aspects of evolution, such as faster charging speed, better chassis response, and the charming Porsche logo, what is there to hesitate about?
