CCTV News:The pouring of the dome outside the nuclear island of Unit 1 of Taipingling Nuclear Power Station in Huizhou, Guangdong Province was completed on May 30, which means that the first ecological nuclear power station in China has completed the construction of the main structure of the first unit. Unit 1 is scheduled to be completed and put into operation in 2025, which is also the first "Hualong No.1" nuclear power unit in Guangdong-Hong Kong-Macao Greater Bay Area, and will provide 10 billion kWh of clean electricity every year.　

The reporter came to the dome of Unit 1 of Taipingling Nuclear Power Station. With the completion of the concrete pouring in the last area, the main structure of the containment of Unit 1 was officially completed. It is equivalent to putting a set of solid "armor" on the nuclear power unit, which can not only withstand the powerful impact of hundreds of tons from the outside world, but also resist the magnitude 9 earthquake and the magnitude 17 typhoon.

The outer containment of the nuclear island of the unit completed this time is a hemispherical dome structure with a radius of 36 meters and a height of about 11 meters, and the area is about the size of five basketball courts. This huge dome is densely covered with steel bars, which can form multiple protections with the inner containment and steel lining, and tightly lock the high-temperature radiation during the operation of the nuclear power unit inside.

Deng Liangwen, technical director of Taipingling Nuclear Power Project Department of China Construction Second Bureau, introduced that the main body adopts prestressed reinforced concrete tube structure, each steel bar has a diameter of 40 mm, which is twice the diameter of ordinary civil steel bars, and the content of concrete steel bars per cubic meter has reached that of ordinary civil buildings. Three times.

Taipingling Nuclear Power Plant plans to build six independent three-generation nuclear power units of "Hualong No.1" with a million kilowatts, which will be implemented in three phases. At present, Unit 1 is in the critical stage of installation and commissioning, Unit 2 is entering the peak period of equipment installation, and the two units are scheduled to be completed and put into use in 2025. A single unit will be able to meet the annual electricity demand of 1 million people every year.

Zhang Guoqiang, chief commander of high-quality nuclear power construction in Taipingling, CGNPC, said that after the project is completed and put into operation, the annual power generation will exceed 50 billion kWh, which can reduce the consumption of standard coal by over 15 million tons, reduce carbon dioxide emission by about 41.2 million tons, and the environmental protection benefit is equivalent to planting nearly 113,000 hectares of forest.

How to divide nuclear power technology into generations? What are their characteristics?

The reporter combed the blue book "China Nuclear Energy Development Report 2024" released recently. The data shows that up to now, there are 26 nuclear power units under construction in China, with a total installed capacity of 30.3 million kilowatts, and both the number under construction and the installed capacity remain the first in the world.

According to experts, from the perspective of intergenerational division of nuclear power plants, the first generation of nuclear power plants is an early prototype reactor, which proves the technical feasibility of nuclear power generation.

The second generation nuclear power plant is a large commercial nuclear power plant developed and built on the basis of the first generation nuclear power plant, which proves the economic feasibility of nuclear power generation. At present, most nuclear power plants in the world belong to the second generation.

The third generation refers to the advanced light water reactor nuclear power plant, which is safer and more powerful. The models include the American PWR AP1000 and China’s self-developed "Hualong No.1".

The fourth generation is the most advanced nuclear power plant at present, which is characterized by good safety, small waste production, high economy and prevention of nuclear proliferation, and is the long-term development trend of nuclear energy. China’s Huaneng Shidaowan high-temperature gas-cooled reactor nuclear power plant is the first fourth-generation nuclear power plant put into commercial operation in the world, which indicates that China has reached the world leading level in the field of fourth-generation nuclear power technology.

　　After Hunan Public Security Bureau detected Xinhuang’s "case of burying a corpse on campus" in the special struggle to eliminate evils, the case of "teacher Li Shangping was shot dead" was also refocused by the media.

　　Li Shangping’s family saw hope again, and they began to be busy, trying to recall the details of that year to visiting journalists.

　　On April 26, 2002, Li Shangping, a teacher in Heshan District, Yiyang, Hunan Province, was shot dead. Family members and people rumored that his death was related to a reported incident, and the case has not been closed so far.

　　In the past seventeen years, grief and helplessness have enveloped this family that has lost its backbone: Liu Yune, the wife of Li Shang Ping, who is also a teacher, left her hometown because she was refused to transfer her job and remarried a few years later; Li Sanbao, the father of Li Shang Ping, died in anger in 2012; At the time of the incident, Li Shangping’s 5-year-old son Li knew that he had been admitted to graduate school now, perhaps because of his father’s reasons, and he was silent.

　　Liu Yune and Li Shangjia (Li Shangping’s sister) said that for 17 years, their families were afraid to mention Li Shangping’s case in front of Li Zhi, for fear that he would be sad. And Li know also deliberately avoided all topics related to his father.

　　"He is a smart and sensible child. He would rather search his father’s case online than ask his family." Liu Yune said that the delicate son was probably afraid that his elders would be sad and never asked.

　　Report the past

　　When it comes to meeting Li Shangping for the first time, Liu Yune, a female teacher who has been tortured by fate for seventeen years, has a slightly sweet mouth.

　　In 1995, they were introduced by colleagues and got married the following year. In Liu Yune’s view, Li Shangping is a young man with "high IQ, talent, sense of justice, and sincerity".

　　Liu Yune said that Li Shangping’s talent is extraordinary: Li Shangping, who teaches English, did not have to play it through a tape recorder at that time, but spoke fluent English himself; He also worked part-time in the graphic channel of Yiyang TV station at that time to collect, write and process manuscripts; Before computers became popular, he bought a desktop computer and stayed up until after 2 am every night.

　　Liu Yune didn’t know until later that since January 2002, Li Shangping has been using the name of "Laojiu" every night to question the fact that more than 600 teachers in Longguangqiao Town have been deducted from their salaries on the Internet.

　　Li Shang’s diary before his life shows: "On March 15th, 2002, I called the mayor’s hotline and the Heshan district government to complain, but it was useless. They just kicked the ball at each other. In the evening, I wrote a paragraph titled "The salary of 800 teachers in Yiyang, Hunan Province was hacked in December 2001! "(Note: According to Southern Weekend, there were actually 635 teachers in the town at that time), posted them on the forum of Hunan Jingshi and the column of" People’s Voice "of Red Net, and sent emails to some media in Hunan and" Focus Network Talk "of Xinhuanet."

　　The contents of Li Shang Ping’s diary were confirmed by The Paper reporters: On January 15th, 2002, Li Shangping, in the name of netizen "Laojiu", reflected the phenomenon that teachers’ salaries were deducted and misappropriated on Hunan Red Net. On the same day, a letter of complaint was sent to the "Focus Network Talk" column of Xinhuanet.

　　On March 15th, 2002, Li Shangping once again wrote in the name of "Laojiu" that the salary of 800 teachers in Yiyang, Hunan Province was hacked in December 2001! The article was published in the forum of Hunan Jingshi and the column of "People’s Voice" of Red Net, and sent to some media in Hunan and "Focus Network Talk" of Xinhuanet by email.

　　Li Shangping’s online post attracted the exposure of local media in Hunan Province on the withholding of wages.

　　Liu Yune recalled that after the teachers got the deducted wages, Li Shangping continued to recover the wages owed before.

　　According to Liu Yune’s recollection to The Paper, around mid-April 2002, Li Shangping’s mood suddenly became depressed, and she was told inexplicably that maybe one day he would die in "an unknown situation".

　　Just a few days after Li Shangping said this to his wife, Li Shangping was shot and killed.

　　According to the report entitled "A" tartar "teacher was shot by a killer in Yiyang, Hunan Province" on July 18th, 2002 in Southern Weekend, after Li Shangping’s death, the "teacher’s salary in Longguangqiao Town" attracted great attention of the Hunan provincial government, which allocated more than one billion yuan from the financial resources to solve the problem of paying teachers’ salaries in more than 20 difficult counties and cities in the province.

　　Transfer denied

　　After Li Shangping was shot, an urgent problem for his family is who will take care of Li Zhi and Li Shangping’s parents who have reached school age?

　　After Liu Yune and Li Shangping get married, they need to take at least two buses to work, and then take a ferry, which takes several hours. And the husband teaches in a school not far from home. Previously, the care of the elderly and children at home mainly depended on Li Shangping.

　　After the incident, in order to take care of the family, Liu Yune said that she had found the Education Bureau many times, hoping to transfer her work to a school slightly closer to home, but failed to do so.

　　"I am chilling, I just want to leave this sad place with my family as soon as possible." Liu Yune said that after this fierce debate, she finally chose to give up.

　　In September 2003, a media reporter contacted Liu Yune, saying that an education group in Jiangsu admired and sympathized with Li Shangping after seeing his deeds and experiences before his death, hoping to help the Li family, and offered to help the Li family move away from sadness and develop in Jiangsu, which could provide work and accommodation.

　　On September 4, 2003, Liu Yune left Yiyang to teach in Jiangsu.

　　Run for the truth

　　Li Sanbao did not accept the invitation to take his wife and grandson to Jiangsu. He gave two reasons at that time: he wanted to stay in Yiyang for his son to find the truth in his lifetime; You can’t let your son’s soul go home without his family.

　　After the incident, Li Sanbao and his wife endured the pain of losing their son in the next year and have been running for the truth about their son’s death.

　　Li Shangjia said that in order to seek the truth, parents first went to public security departments at all levels to inquire about the progress of handling cases. Once, in July of 2005, her father came home from Changsha with a look that made her afraid to look straight. I saw my father sitting motionless on the sofa, muttering to himself. Li Shangjia bent down to comfort his father. When he approached, Li Sanbao immediately turned his head to the corner and sobbed.

　　In Li Shangjia’s view, his father, who had been teaching for 38 years, was a stubborn man, and rarely showed uncontrollable emotions in front of his children in the past.

　　Li Shangjia recalled that because he didn’t know the way and was old and carsick, every time his parents went to Changsha, they were very bitter: before leaving, they would bring a few steamed buns to satisfy their hunger. Even in the hot summer of July, they were reluctant to buy a bottle of water. In the heart of the elderly, they also planned another thing, "Save money for their grandchildren to study."

　　Later, Li Sanbao and his wife began to collect all kinds of clues about their son’s case.

　　"When people say a little about the case, they will get to the bottom of it." Li Shangjia said that until this judgmental belief was used, he was cheated out of 4700 yuan.

　　In the first half of 2008, a middle-aged man about 50 years old came to Li Sanbao’s house and said that he had been paying attention to Li Shangping’s case and knew some inside information, so he could solve the case quickly through his "high-level relationship". The man offered to go to the "activity" for 20,000 yuan.

　　A few days later, the man hurriedly called Li Sanbao, saying that he was going to see the leader immediately and asked Li Sanbao to take 20,000 yuan to the bus station. Fortunately, Li Shangjia, who initially suspected the identity of a man, insisted on accompanying his father to the bus station. When the man saw someone accompanying Li Sanbao, he turned and left.

　　A few months later, a 25-year-old man claimed that he had a good relationship with the principal person in charge of the procuratorate and could help him to "say hello" and speed up the case, but he needed money to give gifts. A few days later, Li Sanbao took 4700 yuan and followed the man to the gate of the procuratorate. After the man took the money, he said that the person in charge was unwilling to meet the client, and he had to go in alone.

　　Li Sanbao sat at the gate of the procuratorate and waited until after work. Everyone left and never saw the man again.

　　After returning home that day, Li Sanbao was so angry that he didn’t eat dinner. Li Shangjia once again saw his father’s despair.

　　Four years later, in the cold winter, Li Sanbao died.

　　On the eve of his death, he specially told Li Shangjia that he had failed to fulfill his promise to find the truth for his son and hoped that she would not give up.

　　The task force stepped up efforts to solve crimes.

　　In the fourth year after going to Jiangsu to teach, Liu Yune was introduced to marry a local teacher. Fortunately, the current husband is very sympathetic to the Li family’s experience and supports Liu Yune to continue to find the truth for Li Shangping.

　　Every time Liu Yune returns to Yiyang, she will discuss the new news with Li Shangjia and try to get some new conclusions.

　　Besides looking for the cause of Li Shangping’s death, there is also a common focus between Liu Yune and Li Jiaren — — Li knows the healthy growth.

　　In the eyes of his mother and aunt, Li Zhi is a clever, sensible and taciturn child. They attributed Li’s cleverness to his father’s "good genes", while his reticence was mostly due to this unfortunate family.

　　For his son Li Zhi, the most urgent thing to know in the past seventeen years is the truth that his father, who named him "Zhi", was shot.

　　In 2002, when Li Shangping was shot, Li knew that he was five years old (nominal age), and now he has graduated from university and admitted to graduate school. His undergraduate and graduate majors have chosen journalism.

　　Li Shangjia introduced that Li knew that he was close to his grandfather since he was a child. From primary school, his grandfather rode a motorcycle to pick him up and drop him off, rain or shine.

　　In the winter of 2012, grandpa’s death was a great blow to Li Zhi, and he became more reticent. Until he was a freshman, Li knew that he had called his mother and cried bitterly, saying that he would dream of grandpa riding a motorcycle to pick him up every night.

　　There is a tacit understanding between the elders and Li Zhi, and they won’t mention the shooting in that year in front of each other. The careful Liu Yune found that his son often logged into his father’s online memorial hall.

　　"He knows more information from the Internet than we adults, but he is afraid that his elders will be sad. For seventeen years, he has never asked." Liu Yune said that her son would call her and grandma every two days to ask for help.

　　The deadlock was broken until the other day.

　　On July 2, Liu Yune called Li Zhi and said, "Son, you must be careful outside, and be careful that those who have harmed your father will harm you."

　　"Well, mom, I know, don’t worry." Li knows the answer.

　　After the exposure of Xinhuang’s "case of burying a corpse in the campus playground", the "Li Shangping case" was brought up by the media again, and the Li family once again faced the media intensively.

　　Liu Yune and Li Jiaren burst into tears when they were interviewed by reporters. At the end of the interview, I will ask the media not to interview Li Zhi, "The pain of the older generation will be left on the older generation and solved by the older generation."

　　"I just hope he can live a safe, healthy and happy life." Li’s family members almost unanimously expressed the same view.

　　To everyone’s comfort, on July 2, the Hunan Provincial Public Security Department released a message: 17 years ago, Li Shangping, a teacher in Heshan District, Yiyang City, Hunan Province, was shot dead. Yiyang Public Security Bureau has been investigating the case. At present, the task force has increased its elite strength and intensified its efforts to solve the case. The Provincial Public Security Department has assigned criminal investigation experts to guide the case.

　　On the evening of July 9, the main person in charge of Heshan Public Security Bureau of Yiyang City Public Security Bureau came to Lijia and said: For seventeen years, Yiyang Public Security Bureau has been trying to investigate the shooting of Li Shangping; I hope that the family members will give feedback to the public security; The role of the media has been achieved, and now the provincial and municipal public security departments have deployed capable forces to guide the investigation, and ultimately it is up to the public security to handle the case.

In recent years, the Ministry of Public Security has focused on the telecom network fraud that people hate, comprehensively strengthened the construction of "four specialties and two synergies", and organized public security organs across the country to further promote the prevention and control work with unprecedented efforts and measures, effectively curbing the rapid rise of cases and effectively safeguarding the legitimate rights and interests of the people. At present, the crime situation of telecommunication network fraud is still grim, with 10 common fraud types accounting for nearly 80%, such as billing rebate, false network investment and wealth management, false network loan, impersonating e-commerce logistics customer service, impersonating public security law and false credit reporting, among which billing rebate fraud has the highest incidence rate, accounting for about one third of the cases, and false network investment and wealth management fraud has the largest amount of losses, accounting for about one third of the losses.

Brush-off rebate fraud

Online rebate fraud has gradually evolved into a major type of fraud with the largest variety and the fastest change. It has become the main drainage method for other complex frauds such as false investment and wealth management, loans, and other illegal crimes such as online gambling and online pornography. Major cases of being defrauded of more than one million yuan have occurred from time to time. Most of the deceived people are school students, low-income groups and unemployed people.

[Typical Case 1] Shao saw the message of "free gift, praise comments and commission return" and the QR code in the WeChat group, scanned the code, contacted the customer service and downloaded an APP as required, and then did the brushing task under the guidance of the receptionist in the APP. After completing five small tasks, I received the corresponding commission, and all of them can be withdrawn to the bank card. Shao Mou started to subscribe for a larger portfolio task list, and invested a total principal of 110,000 yuan. However, after completing the task as required, it was found that it was impossible to withdraw cash. The APP "receptionist" said that Shao’s operation error caused a "card slip" and he had to do another compound task to withdraw cash. Shao only found out that he was cheated at this time.

False network investment and wealth management fraud

In such cases, some fraudsters drag the victims into the so-called "investment" group chat in various ways, and then pretend to be investment tutors and financial advisers to send false news of investment success or "live classes" to defraud the victims’ trust; Some determine the marriage relationship with the victim through the dating platform, and then defraud the victim’s trust on the grounds of having special resources and loopholes in the platform to obtain high financial returns. Subsequently, the fraudsters induced the victim to open an account on the false investment platform to invest, and gave the victim a rebate for the small investment in the early stage. Once the victim increased the capital investment, it would be impossible to withdraw cash. Most of the deceived people are single people with certain income and assets or groups keen on investing and stock trading.

[Typical Case 2] While watching the live broadcast of stock trading knowledge on a live broadcast platform, Yu received Friend Request, who claimed to be the anchor. After a private chat, the two sides added QQ friends, and the other party will pull into an investment exchange group in a certain place. When Yu saw other people investing in an APP in the group, he downloaded the APP and made investment operations in the APP according to the instructions of the group administrator. The small-scale experiments were successful and successfully cashed out. When Yu felt profitable, he invested a total of 3.47 million yuan in the APP. Until the end of the month, Yu found that the balance in the APP could not be withdrawn and was blacked out by the other party, only to find that he was cheated.

False online loan fraud

Fraudsters post advertising information on handling loans, credit cards and cash withdrawals through online media, telephone calls, text messages, social tools, etc., and then pretend to be employees of banks and financial companies to contact the victims, falsely claiming that they can "mortgage-free", "exempt letters" and "lend quickly" to trick the victims into downloading fake loan apps or logging on fake websites. Then, on the grounds of collecting "handling fee", "deposit" and "agency fee", the victim is tricked into transferring money and remittance. After receiving the victim’s transfer, the fraudster closes the fake APP or fake website and blackes out the victim. Most of the deceived people are people who have urgent loan needs and are in urgent need of money turnover.

[Typical Case 3] Fan received a call claiming to be the customer service of a financial platform and asked if there was a loan demand. Because Fan just needed capital turnover, he added a WeChat friend of the other company and downloaded a "loan" APP. After Fan APPlied for a loan on the app, the other party asked him to transfer money on the grounds of paying membership fees, unfreezing money, and proving repayment ability. After Fan transferred 137,000 yuan to the other party, the other party still said that the loan conditions were not met and he could not lend, and then he lost contact. Fan found that the downloaded APP could not log in, only to find that he was cheated.

Pretending to be an e-commerce logistics customer service fraud

Fraudsters pretend to be e-commerce platforms or customer service of logistics express companies, falsely claiming that the goods purchased online by the victims have quality problems or the goods sold have been taken off the shelves due to violations, and inducing the victims to provide information such as bank cards and mobile phone verification codes on the grounds that they need to pay for "claim refund" or "reactivate the store", and guiding the victims to transfer money and remit money through screen sharing or requesting to download designated apps. Most of the deceived people are consumers who often shop online on e-commerce platforms or shop operators of e-commerce platforms.

[Typical Case 4] Du Mou received a call claiming to be "customer service" of an online shop, saying that the hair dye he bought a few days ago had quality problems, and now he needs to make a refund to Du Mou, and Du Mou believes it. The "customer service" induced Du to download an APP, through which he opened the screen sharing function of the mobile phone and followed the instructions. Subsequently, Du’s mobile phone received a text message that the bank card was transferred to 20,000 yuan, only to find that it was cheated.

Pretending to be a public security fraud

The fraudsters obtained the victim’s personal identity information through illegal channels, then pretended to be the staff of the public security organs, contacted the victim by telephone, WeChat, QQ, etc., threatened and intimidated the victim on the grounds that he was suspected of money laundering, illegal entry and exit, possession of drugs by express delivery, passport problems and other illegal crimes, demanded to cooperate with the investigation and keep it strictly confidential, and showed the victim false legal documents such as "arrest warrant", "wanted order" and "property freezing book" to increase credibility. At the same time, the victim is required to go to a closed space such as a hotel, "cooperate" with his work under the condition of blocking contact with the outside world, and transfer the funds to a "safe account" to commit fraud.

[Typical Case 5] Yang received a phone call claiming to be a policeman of Shanghai Public Security Bureau, claiming that a bank account under Yang’s name was suspected of illegal money laundering and asked him to go to Shanghai Public Security Bureau for handling. Yang said that he couldn’t go. The other party asked him to add QQ friends and sent a file showing Yang’s photos, which contained content such as being sentenced for money laundering. Yang was afraid. Subsequently, the other party asked Yang to cooperate with the investigation in the unoccupied room on the grounds of involving police secrets, and said that if Yang wanted to remove the suspect, he needed to transfer all the money in the card to a "safe account", and the money would be returned after the case was found out. Yang then transferred 50,000 yuan to the bank account provided by the other party. Later, due to the request of the other party to delete all chat records, Yang discovered that he was cheated.

False credit fraud

Fraudsters pretend to be banks, China Banking and Insurance Regulatory Commission staff or online loan platform staff to establish contact with the victims, falsely claiming that the accounts previously opened by the victims through campus loans, student loans, etc. have not been cancelled in time, and the relevant accounts need to be cancelled; Or lie that the victim’s credit payment tools such as credit cards, flower beds, and borrowing beds have bad records, and it is necessary to eliminate relevant records, otherwise personal credit information will be seriously affected. Subsequently, on the grounds of eliminating bad credit records and verifying running water, fraudsters induced victims to make loans on online loan platforms or Internet finance apps, and transferred the money to their designated accounts, thus committing fraud.

[Typical Case 6] Wang received a phone call from a staff member who claimed to handle high-interest loans in China Banking and Insurance Regulatory Commission. The other party said that Wang had a bad record caused by loans overdue, which would affect his personal credit information. After some communication, Wang believed the identity of the other party and transferred money to three different accounts of the so-called "China China Banking and Insurance Regulatory Commission Certified Docking Account" three times, totaling 250,000 yuan, of which 230,000 yuan was the money borrowed by Wang from three financial platforms. "What other bank cards and loan apps have you used?" When the other party repeatedly asked this question, Wang just woke up and realized that he had been cheated.

False shopping and service fraud

The fraudsters posted advertisements such as "low price discount", "overseas purchasing" and "shopping in 0 yuan" on WeChat group, friends circle, online shopping platform or other websites, or provided advertisements of special services such as "writing papers", "private detectives" and "tracking and positioning" to attract the attention of victims. After getting in touch with the victim, the fraudster induced him to add friends through WeChat, QQ or other social software for discussion, and asked for private transfer on the grounds that private transactions could save "handling fees" or be more convenient. After the victim pays, the fraudster will trick the victim into continuing to transfer money and remit money on the grounds of paying customs duties, deposits, transaction taxes and handling fees, and then blacken the victim afterwards.

[Typical Case 7] Li saw an advertisement for selling a valuable liquor on the Internet, so he added the details as a WeChat friend according to the contact information left by the other party. The other party claims to be a factory direct seller, and can provide internal prices, but it needs to be traded privately. After agreeing on the price, Li transferred 11,000 yuan to his account. A few days later, when Li asked the other party for logistics distribution information, he found that he was blacked out and found that he was cheated. In order to find a liar, Li added a self-proclaimed private detective as a friend after searching for a private detective on the Internet. The other party said that he could find someone for Li through his mobile phone, but he had to pay 10,000 yuan of labor fee first. After transferring 10,000 yuan to the account provided by the other party, Li found that he was blacked out again and was deceived twice.

Pretending to be a leader and being familiar with human fraud

Fraudsters use the photos and names of the victim’s leaders, acquaintances or children’s teachers to "package" social accounts, add the victim as a "fake" friend, or pull it into WeChat chat groups. Subsequently, the fraudsters expressed concern for the victims as leaders and acquaintances, or imitated the tone of leaders, teachers and others to defraud the victims. Then ask the victim to transfer money to the designated account on the grounds that it is inconvenient to come forward and answer the phone, and constantly urge the victim to transfer money as soon as possible on the pretext of time constraints, thus implementing fraud.

[Typical Case 8] Li’s QQ account was pulled into a work group by fraudsters, and the names of the members in the group were all staff members of the company, so it was not verified again. A few days later, Li received a group message: the "general manager" pretending to be a liar said that he needed to pay the other party’s project money and asked Li to check how much money was left in the company account. After Li checked the funds in the company’s account, the "general manager" impersonated by the liar asked Li to transfer all the funds in the account to the other party’s designated account, and urged Li to transfer money quickly on the grounds of urgency. For fear of offending the "leader", Li transferred all 400,000 yuan from the company’s account. After the general manager of the company received a short message from the bank, Li found out that he was cheated.

Fraudulent trading of online game products

Fraudsters publish advertisements for buying and selling online game accounts, props and cards on social and game platforms, or get game props for free and at low prices, participate in lottery activities and other related information. After the victim actively contacts with him, the fraudster induces the victim to bypass the formal platform and conduct private transactions with him on the grounds that private transactions are cheaper and more convenient; Or ask the victim to add a so-called customer service account to participate in the lucky draw, and ask the victim to pay "registration fee", "unfreezing fee" and "membership fee" on the grounds of operational mistakes and insufficient grades, and then the victim will be blacked out after success.

[Typical Case 9] When playing a game, Shen saw a message in the game chat box "Join the group and get game props for free". After applying for joining the group, a person with the net name "dispatcher" told Shen that he could get a lot of game benefits by scanning the QR code in the group. After Shen used WeChat to scan the QR code and fill in the relevant information, the webpage suddenly showed that WeChat would be frozen, and Shen contacted the "dispatcher". The other party said that Shen had improperly operated and pushed a person named "Handler" to him. The "processor" said that it is necessary to prove that WeChat is my use through transfer, and all funds will be refunded after verification. At the request of the other party, Shen transferred 18,000 yuan to the designated account, only to be found cheated after being blacked out by the other party.

Marriage and dating fraud

Fraudsters collect a large number of self-portraits and life photos of "Bai Fumei" and "Gao Fushuai" through the Internet, create different identity images according to the scripts, and then publish personal information on dating websites. After establishing contact with the victim through social software, fraudsters use photos and pre-designed false identities to defraud the victim’s trust, and operate the love relationship with the victim for a long time. Subsequently, the fraudsters demanded money from the victims on the grounds that they were in urgent need of money and helped the fund turnover of the project, and constantly changed their reasons to ask them to transfer money according to the financial situation of the victims until the victims found out that they were cheated.

[Typical Case 10] Ms. Xie met a "foreign soldier" on the Internet. The other party claimed to be a military doctor stationed in a certain country and liked China culture very much. She hoped to settle in China in the future. In the process of chatting with this "soldier", Ms. Xie was gradually moved by the elegant conversation and daily concern of the other party, and confirmed the love relationship with the other party without meeting each other. "Soldier" said that he would transfer all his property to China so that he could live with Ms. Xie, but because she was intercepted by the customs, she needed Ms. Xie’s help to pay a fee to get through. Ms. Xie transferred 50,000 yuan to the account provided by her, and then transferred more than 400,000 yuan to the bank account provided by the other party because of the need to pay "thawing fee" and "handling fee", until she was blacked out by the other party, and Ms. Xie found out that she was cheated.

CCTV News:A few days ago, it was reported that the US government was asking South Korea to reply whether to join the "Four-Party Alliance of Chips" led by the US before August. The South Korean side indicated that it was discussing with the US ways to strengthen cooperation in chip manufacturing. At the regular press conference held by the Ministry of Commerce today (July 21st), some media asked the Ministry of Commerce what comments it had on this development and how it viewed the possible impact of the alliance on China’s semiconductor industry. A spokesperson for the Ministry of Commerce responded.

Shu Yuting, spokesperson of the Ministry of Commerce:The stability of industrial chain supply chain is a global issue of great concern to all parties at present. China believes that no matter what framework arrangement, it should be inclusive and open, not discriminatory and exclusive; We should promote the stability of the global industrial chain supply chain, rather than damage and split the global market. Under the current situation, strengthening the open cooperation of industrial chain supply chain and preventing fragmentation is beneficial to all parties concerned and the whole world.

Domestic colleges and universities expose plagiarism again.

Recently, The Paper (www.thepaper.cn) received a report that a master’s degree thesis of Northeastern University was similar to a master’s degree thesis of Shanghai Jiaotong University in a large area.

These two papers are respectively the master’s thesis of Sun Yong, a graduate of Northeastern University majoring in mechanical engineering in 2008, "Optimal Design and Simulation Analysis of the Pneumatic System of Vacuum Cleaner" (hereinafter referred to as "Sun Yong’s thesis") and the master’s thesis of Li Bihong, a graduate of Shanghai Jiaotong University majoring in vehicle engineering in 2006, "Structural Design and Optimization of the Pneumatic System of Vacuum Cleaner" (hereinafter referred to as "Li Bihong’s thesis").

Cover of Li Bihong’s paper

Li Bihong’s thesis was completed in February 2006, and Sun Yong’s thesis was completed in January 2008. In terms of time, Sun Yong’s thesis was completed nearly two years later than Li Bihong’s.

The Paper reporter downloaded the above two papers from Wanfang Data Knowledge Service Platform. After comparison, it is found that the main contents of the two papers are highly similar, and several paragraphs are almost verbatim, and nearly 80% of the references are completely consistent.

On the afternoon of April 2, The Paper contacted the Academic Committee of Northeastern University and the Scientific Research Office of the School of Mechanical Engineering and Automation of Northeastern University. The staff of both institutions said that they were not aware of the matter and could not give a specific reply for the time being.

Later, The Paper contacted Yang Ying, the instructor of Sun Yong’s thesis and a professor at the School of Mechanical Engineering and Automation of Northeastern University. "Just follow the normal (reporting) channels." Yang Ying said to The Paper.

The content of the text is highly similar

After comparing the two papers, The Paper found that the research objects of the two papers are the gas path system of the vacuum cleaner.

The structure of Li Bihong’s paper is divided into five chapters, namely "Introduction", "Brief introduction of the air path system of the vacuum cleaner", "Structural design and optimization of the suction port of the vacuum cleaner", "Structural design and improvement of the gravity settling chamber of the vacuum cleaner" and "Summary and discussion".

Compared with the structure of Li Bihong’s paper, Sun Yong’s paper has two more chapters, which are divided into seven chapters, namely, introduction, brief introduction of vacuum cleaner and its working principle, analysis of working medium characteristics of gas pump, dust particle movement mechanism and design of suction port, simulation analysis and structure optimization of suction port, simulation analysis and optimization design of gravity settling chamber and summary and discussion.

Although the structural design of the two papers is different, part of the text is highly similar.

The third section of the first chapter of Li Bihong’s thesis.

The second section of the chapter "Introduction" of Sun Yong’s thesis.

Taking the first chapter "Introduction" as an example, Li Bihong’s paper wrote in the first paragraph of the third section of this chapter "Research Status and Application of Vacuum Cleaning Vehicles at Home and Abroad": "In developed countries abroad, the research on vacuum cleaning vehicle technology is gradually developed and perfected with the improvement of road sweeper performance. According to the relevant information, the technical research of vacuum cleaner abroad mainly focuses on these three aspects: 1. Providing the operating performance of products. New technologies such as control and information are applied to the vacuum cleaner, and an intelligent vacuum cleaner is developed. For example, the vacuum cleaner in Elgen, USA, adopts electromechanical integration design, applies microcomputer and automatic control technology, and has 57 functional designs; The vacuum cleaner uses more than a dozen sensors with superior performance, and transmits all kinds of information with different working conditions, different media, different parts, different environments and different functions to the control center (single chip microcomputer). After receiving the relevant information, the control center comprehensively processes the information, and then sends control instructions to the actuator to control the movement of relevant parts of the vacuum cleaner. 2. Improve the working efficiency of the gas path system. Optimize the product structure and improve the operation effect. For example, there is an’ S’ type dust particle separator in the large-volume garbage bin of EIGLN dust collector in the United States, which can separate dust particles more effectively and increase the dust removal efficiency. 3. Innovative product development methods. Combining virtual design and manufacturing technology with computational fluid dynamics analysis technology, it is applied to the design and production process of vacuum cleaner, forming digital design and production mode, speeding up product renewal cycle and improving product efficiency. "

The second section of the "Introduction" chapter of Sun Yong’s paper is "Research Status and Application of Vacuum Cleaners Abroad". In the first paragraph, the specific expression is: "The application of vacuum vacuum cleaner was earlier in foreign countries, and the research on vacuum cleaner technology was gradually developed and perfected with the continuous improvement of the performance requirements of public sweepers. According to relevant information, the research on vacuum cleaner technology abroad is mainly focused on the following aspects: 1. Providing product operability technology: applying new technologies such as control and information to vacuum cleaner, and developing intelligent vacuum cleaner. For example, the vacuum cleaner in Elgen, USA, adopts electromechanical integration design, applies microcomputer and automatic control technology, and has 57 functional designs; The vacuum cleaner uses more than a dozen sensors with superior performance, and transmits all kinds of information with different working conditions, different media, different parts, different environments and different functions to the control center (single chip microcomputer). After receiving the relevant information, the control center comprehensively processes the information, and then sends control instructions to the actuator to control the movement of relevant parts of the vacuum cleaner. 2. Improve the working efficiency of the gas path system: By optimizing the structural components of the gas path system and adopting different dust removal and filtering materials, the volume of the vacuum cleaner can be reduced and the working effect can be improved as much as possible. For example, there is an’ S’ type dust particle separator in the large-volume garbage bin of EIGLN in the United States, which can separate dust particles more effectively and increase the dust removal efficiency. 3. Innovative product development methods: combining virtual design and manufacturing technology with computational fluid soft mechanics analysis technology,When it is applied to the design and production process of vacuum cleaner, it forms a digital design and production mode, speeds up the product update cycle and reduces the product development cost. "

In the above two paragraphs, Sun Yong’s paper is almost identical with Li Bihong’s paper except for modifying individual wording, changing "fluid mechanics" into "fluid soft mechanics" and the difference of three punctuation marks.

Screenshot of the second chapter of Sun Yong’s paper on "the overall structure of vacuum cleaner".

For another example, the first section of Chapter 2 of Li Bihong’s thesis "The overall structure of vacuum cleaner" reads: "The vacuum cleaner is modified by adding a special device on the second-class chassis of the truck. The special device mainly includes two parts: gas path system and hydraulic control system. The gas path system is the core part of the vacuum cleaner, and its working condition determines the overall performance of the vacuum cleaner. The gas path system includes two subsystems: dust collection and dust removal, which are mainly composed of high-pressure centrifugal fan, gravity settling chamber, dust suction port, secondary dust collector, ventilation pipeline and other components. There are two main forms of power supply for the gas path system: single engine type and double engine type. " Li Bihong’s paper also presents the principle of single engine and double engine in the form of legend.

Sun Yong wrote in the second section of the second chapter "Overall structure of vacuum cleaner": "Generally, vacuum cleaner consists of a general vehicle chassis and a van-type working device. The chassis is usually the second-class chassis of freight cars, and the working device mainly includes two parts: the gas path system and the hydraulic control system. The gas path system is the core part of the vacuum cleaner, and its working condition determines the overall performance of the vacuum cleaner. The gas path system includes two parts: dust suction and dust removal, and is mainly composed of high-pressure centrifugal fan, gravity settling chamber, dust suction port, subsequent dust collector, ventilation pipeline and other components. The gas path system can be divided into single engine type and double engine type according to the different power supply forms. " Sun Yong’s paper also presents the principle of single engine and double engine by drawing.

There is no difference between the above two paragraphs except that the first sentence and the last sentence are simply rewritten, and the "secondary dust collector" is changed to "subsequent dust collector", and other contents, including diagrams, are all the same.

Part of the contents of the fourth and fifth chapters of Sun Yong’s thesis are similar to some of the contents of the third chapter of Li Bihong’s thesis.

Screenshot of the content of the third chapter of Li Bihong’s paper "The take-off process of dust particles".

Screenshot of the fourth chapter of Sun Yong’s paper "The take-off process of dust particles".

For example, in the third chapter of Li Bihong’s paper, he wrote: "Under the action of wind, when the average wind speed is about equal to a certain critical value, individual prominent dust particles start to vibrate or swing back and forth under the influence of turbulent velocity and pressure pulsation, but they do not leave their original positions; When the wind speed increases beyond the critical value, the vibration will also be strengthened, and the head-on resistance and rising force will increase correspondingly enough to overcome the action of gravity. The larger rotating torque urges some of the most unstable dust particles to roll or slide along the bed surface first. Due to the diversity of geometric shapes and spatial positions of dust particles and the variability of stress conditions, during the rolling process, some dust particles will gain great momentum when they meet with raised dust particles on the surface or are impacted by other moving dust particles. Dust particles with great impulse will quickly change their movement mode, from horizontal movement to vertical movement, and suddenly jump up into the airflow to start moving. "

The fourth chapter of Sun Yong’s thesis also has a section on "the take-off process of dust particles". The specific content is as follows: "Under the action of wind, when the average wind speed is about equal to a certain critical value, individual prominent dust particles start to vibrate or swing back and forth under the influence of turbulent velocity and pressure pulsation, but they do not leave their original positions;" When the wind speed increases beyond the critical value, the vibration will also be strengthened, and the head-on resistance and rising force will increase correspondingly enough to overcome the action of gravity. The larger rotating torque urges some of the most unstable dust particles to roll or slide along the bed surface first. Due to the diversity of geometric shapes and spatial positions of dust particles and the variability of stress conditions, during the rolling process, some dust particles will gain great momentum when they meet with raised dust particles on the surface or are impacted by other moving dust particles. Dust particles with great impulse will quickly change their movement mode, from horizontal movement to vertical movement, and suddenly jump up into the airflow to start moving. "

The above two paragraphs are exactly the same.

Screenshot of the content of the first section of chapter 3 of Li Bihong’s paper, "Performance simulation analysis of dust suction port".

Screenshot of the fifth chapter of Sun Yong’s paper "Performance Simulation Analysis and Structure Optimization of the Dust Suction Port".

For another example, the third chapter of Li Bihong’s thesis mainly discusses "the performance simulation analysis of the dust suction port". This section begins with an overview of computational fluid dynamics, which mainly involves the application field of computational fluid dynamics, the simulation process of computational fluid dynamics, CFD software structure and so on. Among them, the first paragraph reads: "Computational Fluid Dynamics (CFD) is the product of the combination of modern fluid mechanics, numerical mathematics and computer science. It analyzes the system including fluid flow and heat conduction through computer numerical calculation and image display. The basic idea of CFD can be summed up as follows: replace the original continuous physical fields in time domain and space domain, such as velocity field and pressure field, with a series of sets of variable values at a limited number of discrete points, establish algebraic equations about the relationship between field variables at these discrete points through certain principles and methods, and then solve the algebraic equations to obtain the approximate values of field variables. "

The title of Chapter 5 of Sun Yong’s paper is "Performance Simulation Analysis and Structure Optimization of Dust Suction Nozzle", which also begins with "Overview of Computational Fluid Dynamics", including "Application Field of Computational Fluid Dynamics", "Simulation Process of Computational Fluid Dynamics" and "CFD Software Structure". The first paragraph reads: "Computational Fluid Dynamics (CFD) is the product of the combination of modern fluid mechanics, numerical mathematics and computer science. It analyzes the system including fluid flow and heat conduction through computer numerical calculation and image display. The basic idea of CFD can be summed up as follows: replace the original continuous physical fields in time domain and space domain, such as velocity field and pressure field, with a series of sets of variable values at a limited number of discrete points, establish algebraic equations about the relationship between field variables at these discrete points through certain principles and methods, and then solve the algebraic equations to obtain the approximate values of field variables. "

The two paragraphs listed above are verbatim.

Taking the fourth chapter of Li Bihong’s thesis and the sixth chapter of Sun Yong’s thesis as an example, it is found that the two chapters are similar in a large area.

For example, when discussing the spatial structure of the gravity settling chamber, Li Bihong wrote: "The gravity settling chamber of the vacuum cleaner is installed on the vehicle chassis, so the size of the vehicle chassis is a factor that affects the structural design of the settling chamber. The length, width and height dimensions of the gravity settling chamber shall not exceed the dimensions defined by the vehicle chassis. The size of gravity settling chamber should be arranged according to the principle of short, wide and long. If the settling chamber is too high, the dust particles on the upper part will settle to the bottom for a long time, and the dust particles will often be taken away by airflow before falling to the bottom. After the cross-sectional area of circulation is determined, the width increases and the height can be reduced. However, in the vacuum cleaner, the ash box and the settling chamber are integrated, and the height of the ash box must be reduced as much as possible on the basis of ensuring the requirements of solvent C. Lengthening the length of the settling chamber can improve the dust removal effect of the settling chamber. "

The sixth chapter of Sun Yong’s paper also has related discussion, specifically: "The gravity settling chamber of vacuum cleaner is installed on the vehicle chassis, so the size of the vehicle chassis is a factor that affects the structural design of the settling chamber. The length, width and height dimensions of the gravity settling chamber shall not exceed the dimensions defined by the vehicle chassis. The size of gravity settling chamber should be arranged according to the principle of short, wide and long. If the settling chamber is too high, the dust particles on the upper part will settle to the bottom for a long time, and the dust particles will often be taken away by airflow before falling to the bottom. After the cross-sectional area of circulation is determined, the width increases and the height can be reduced. However, in the vacuum cleaner, the ash box and the settling chamber are integrated, and the height of the ash box must be reduced as much as possible on the basis of ensuring the requirements of solvent C. Lengthening the length of the settling chamber can improve the dust removal effect of the settling chamber. "

The above two paragraphs are exactly the same.

In addition, in the "summary and discussion" section, the summary of Sun Yong’s paper is the same as that of Li Bihong’s paper, except that it does not contain the "subject innovation" of the latter’s paper.

Screenshot of Li Bihong’s paper "Thanks".

Screenshot of Sun Yong’s paper "Thanks".

More than half of the references are consistent, and the words "thanks" are the same.

The two papers are highly similar in content, and there are similarities in references and acknowledgements.

The Paper comparison shows that there are 34 references in Li Bihong’s paper and 33 references in Sun Yong’s paper. Among them, 26 of the 33 references in Sun Yong’s paper are consistent with those in Li Bihong’s paper.

Looking at the thank-you part again, Li Bihong wrote in the first paragraph of the paper "Thanks": "This paper was completed under the careful guidance and care of the tutor Professor Chen Jie, and each chapter embodies the painstaking efforts of the tutor and expresses heartfelt thanks to Mr. Chen for his education and guidance. In the past three years of postgraduate study and life, Mr. Chen’s profound knowledge, rigorous and truth-seeking attitude, dedicated work attitude and innovative spirit have left a deep impression on me, which has benefited me a lot and will be enjoyed for life. "

The first paragraph of Sun Yong’s paper "Thanks" reads: "This paper was completed under the careful guidance and care of my tutor, Professor Yang Ying, and each chapter embodies the tutor’s painstaking efforts. I would like to express my heartfelt thanks to Mr. Yang for his education and guidance again. And I would like to express my gratitude to all the teachers and leaders of Northeastern University who have been teaching me earnestly in the past three years of postgraduate study and life! Their profound knowledge, rigorous and realistic academic attitude and dedicated work attitude left a deep impression on me, which benefited me a lot and will be used for life. "

In the above two paragraphs, many adjectives are the same. At the same time, Li Bihong and Sun Yong thanked their wives and family members with the same words "shared a lot for me, silently supported me and inspired me to finish my studies".

Instructors suspected of plagiarizing papers: follow normal channels

Although Sun Yong’s thesis and Li Bihong’s thesis have a large area of similarities, both master’s degree theses have an Original Statement.

The authors of both papers said that their master’s degree thesis was the result of independent research work under the guidance of their tutors. Except where quotations and acknowledgements have been indicated, it does not include research results that have been published or written by others. Both of the original statements bear the author’s personal signature and date.

Due to the completion time of the paper, Sun Yong’s paper was nearly two years later than Li Bihong’s, and Sun Yong’s paper, which was completed in January 2008, was suspected of copying Li Bihong’s paper.

On the afternoon of April 2, The Paper called the Academic Committee of Northeastern University to verify the alleged plagiarism of Sun Yong’s paper. A staff member told The Paper that they had not received a formal report on this matter and could not give a specific result. If a formal report about academic misconduct or plagiarism is received, the investigation will be accepted.

Subsequently, The Paper contacted the Research Office of the School of Mechanical Engineering and Automation of Northeastern University, and the office staff also said that they were not aware of this matter and needed to know more.

The Paper also contacted Yang Ying, the instructor of Sun Yong’s thesis and a professor at the School of Mechanical Engineering and Automation of Northeastern University. "Just follow the normal (reporting) channels." Yang Ying said this on the phone.

The Paper learned from official website of Northeastern University that in April 2016, Northeastern University published the Detailed Rules for the Investigation and Punishment of Academic Misconduct in Northeastern University in official website, in which Article 14 stipulates that if a student has academic misconduct, the relevant functional departments of the school will give him corresponding punishment according to the relevant regulations on student management according to the identification opinions or reconsideration results. If academic misconduct is directly related to obtaining a degree, he can be treated as delaying the award of a degree, not granting a degree or revoking the degree according to law.

　　BEIJING, July 8 (Yuan Xiuyue) On the 8th, the Disney live-action movie Mulan made its debut. As soon as the trailer was released, Liu Yifei’s makeup caused a heated discussion on the Internet.

　　In the film, Mulan was arranged by her family to go on a blind date, and she was carefully dressed from clothes to makeup. However, Mulan’s makeup seems a little out of line with modern aesthetics. A red face, a yellow forehead, black eyebrows, and red flowers painted between them. Some netizens commented that such makeup could not even hold up the "fairy sister".

　　Then, in the Northern and Southern Dynasties, how did women make up, and what popular makeup did they have?

　　There is a cloud in Mulan Poetry: "When the window is decorated with clouds, it will be yellow for the mirror." Among them, "flower yellow" refers to forehead yellow makeup. In the Northern and Southern Dynasties, influenced by Buddhist culture, women took the makeup of Buddha statues as beauty. Some women were also inspired by the Buddha statue and painted their foreheads yellow. In poetry and prose, the forehead yellow is also called crow yellow, pistil yellow, about yellow and flower Huang Zhi.

　　For example, in the poem "Three Butterflies" by Li Shangyin, "Princess Shouyang wears makeup when she marries, and the eyebrows in the eight-character palace are yellow." Liang Jian Wendi Xiao Gang’s "Beautiful Women" also said: "About the yellow energy efficiency month, cutting gold and making stars skillfully."

　　In addition to painting the forehead yellow, there are yellow hard paper or gold foil cut into patterns and pasted on the forehead. Because it can be cut into stars, moons, flowers, birds and other patterns, it is also called "flower yellow". In Chen Houzhu’s "Picking Lotus Songs", there is: "Note the mouth with the appropriate cleverness, and the flowers will be yellow."

　　In fact, as early as the Warring States period, women began to apply powder and makeup. After the Han dynasty, the number of people wearing red makeup increased day by day. In "Mulan Poetry", there is "A sister hears that her sister is coming, and she will manage the red makeup." The raw material of red makeup is rouge, which is mixed with lead powder and rice flour and applied to cheeks. There are faint red makeup, peach blossom makeup and oblique red makeup.

　　In the Northern and Southern Dynasties, there was plum blossom makeup, that is, plum blossom-shaped makeup was attached to the forehead. It is said that Princess Shouyang, the daughter of Emperor Wu of the Southern Song Dynasty, was lying on her back on the seventh day of the first month. The plum tree in front of the temple was blown by the breeze, and a plum blossom fell right on the princess’s forehead. The forehead is stained like a petal, and it can’t be washed away. Seeing this, women in the palace followed suit and cut plum blossoms and stuck them on their foreheads. Later, plum blossom makeup gradually became a fashion.

　　During the Northern and Southern Dynasties, women attached great importance to face makeup, and developed a variety of styles, including white makeup, purple makeup, Buddha makeup, crow makeup, half-face makeup and so on.

　　White makeup is to apply white powder to the face, not rouge, and pursue the beauty of elegance. Purple makeup, as the name implies, is to apply purple powder to the face, which is made up of rice flour, Hu powder and sunflower juice. Buddha makeup is similar to forehead makeup, except that the whole face is painted yellow.

　　During the Northern and Southern Dynasties, some weird makeup styles were popular, such as crying makeup and half-face makeup. Crow makeup is to apply powder under the corner of your eyes, just like crow marks. Half-face makeup is only half-face, which comes from Xu Fei, the concubine of Emperor Liang Yuan.

　　In fact, whether it is forehead yellow makeup or red makeup, it reflects women’s pursuit of beauty at that time, leaving an indispensable stroke for China’s makeup history and an infinite imagination space for us today. (End)

On August 16th, the spy photos of the first model of Zunjie under HarmonyOS Zhixing were just exposed yesterday. Today, another group of spy photos of the new car M8 were exposed by the media. The new car is between M7 and M9 and is expected to be officially unveiled at the end of the year.

According to spy photos and related information, the new car is close to the M9 in size, and the length of the car is about 5 meters, slightly smaller than the M9. And the news revealed that the new car will adopt a six-seat layout to locate a large SUV.

In terms of details, the front face of the new car is closer to the design style of the M7, and to a certain extent, it is a fusion of the two. The spy photos of this exposure show that there is no luggage rack and lidar on the roof, but earlier, another set of M8 spy photos exposed online showed that the roof has luggage rack and lidar.

Considering that at the end of this month, the car will launch the car M7 Pro without lidar, it is expected that the car M8 will be distributed in one step, and the car with pure vision and intelligent driving will be launched simultaneously. As the basic version of Huawei Intelligent Driving ADS, under the premise of pure vision, it has also supported NAC intelligent driving navigation assistance for national expressways, and supported the ability to automatically go up and down ramps and automatically bypass obstacles such as construction roads and cones.

Earlier, there were also interior spy photos of the M8, which was also the same triple screen design of the M9. The function and style were basically the same as those of the M9. Of course, it is not excluded that only the M9 accessories are directly used for testing vehicles at present.

In addition, in the rear part, we can see that the design of the whole rear of the new car is similar to that of the M9, and it is equipped with the same taillight of M9, and also supports the programming function of light language.

According to the previous plan, the sales target is 600,000 vehicles in 2024, and the M8 is planned to be released and mass-produced this year. At the latest, the new car will be officially unveiled before the end of the year, and we will continue to pay attention to it.

　　Snowflakes are fluttering in the north and rainy in the south. On the 14th, the largest range of rain and snow weather since winter came online. What is the reason for the rain and snow? What will the weather be like in the future? The reporter interviewed relevant experts.

　　The snowfall in the north has a large impact range and strong intensity.

　　Fang Yi, chief forecaster of the Central Meteorological Observatory, said that around the 14th, the snowfall in the north was generally characterized by a large impact range and strong intensity, which was the largest and strongest snowfall in North China since winter. There are small to medium snow or sleet in central Inner Mongolia, Hebei, Beijing, Tianjin, Henan and other places, which gradually weakens after nightfall that day. Snowfall in Liaoning, Shandong and eastern Inner Mongolia will last until the morning or day of the 15th.

　　Just two days ago, the snowfall on the 12 th has already surprised many small partners in the north. It is also snowing, but the snow on the 14th is somewhat different from that of the previous days.

　　Fang Yi pointed out that the difference between the two snowfall processes lies in the different sources of cold air and water vapor. This round of snowfall is due to the continuous eastward movement of cold air in northern Xinjiang and southward along the northwest road. Before the influence of cold air, the ground inverted trough and the low-level southerly wind were significantly strengthened, which transported the warm and humid airflow from the south to the north, which was beneficial to the formation of snowfall in Huanghuai area of North China. On the 12th, the snowfall process was mainly caused by the return of cold air from the East Road. In addition, there was an easterly wind in Bohai Sea to transport water vapor, which led to snowfall in Huanghuai area of North China.

　　Strictly speaking, the snow on the 14th was the third snowfall in Beijing recently. Not only that, since February, there has been obvious snowfall in many places in the north, including Beijing.

　　Chen Lijuan, chief of the Climate Prediction Office of the National Climate Center, said that the precipitation situation is closely related to the coordination of cold air activities, water vapor transport and other conditions. In February, there were two strong cold air processes affecting China. At the same time, the subtropical high in the western Pacific is stronger than normal, and it is north by west, which leads a lot of water vapor from the northwest Pacific and the South China Sea to be transported to China, especially to the north of the Yangtze River, where it merges with the cold air guided by the trough from Mongolia to Northeast Asia, forming favorable conditions for precipitation in the north. Because the temperature is obviously lower than normal, it appears in the form of snowfall.

　　The continuous rain in the south has lasted for a week.

　　Since February 7th, there has been continuous rainy weather in southern China for one week. Fang Yi said that due to the strong and stable subtropical high, the south branch trough is more active, the low trough keeps moving eastward, and the warm and humid airflow is strong, resulting in continuous rainy weather in the south.

　　He said that in the coming week, there will be continuous rainy weather in Jiangnan, South China, Jianghuai, Jianghan, Chongqing and Guizhou. In particular, it should be noted that from 17th to 18th, heavy rain may occur in parts of central and western South China and central and western South China, and the possible secondary disasters should be prevented in time.

　　Fang Yi pointed out that for the northern region, Xinjiang, Tibet, Qinghai and other places will have small to medium snow, local heavy snow or blizzard from 14th to 16th. Around the 18th, there will be a snowfall mainly with light snow in south-central North China, Huanghuai and other places, and moderate to heavy snow may occur in some areas of Huanghuai.

　　Chen Lijuan said that from December 1, 2018 to February 13, 2019, the national precipitation was 29% higher than the normal average, but the spatial distribution was extremely uneven. The eastern region was "less in the north and south, more in the middle", that is, less in the northeast, north China and eastern South China, but more in Jianghuai and Jiangnan, and more in the western region as a whole.

　　Ruixue is a good year, especially for the northern region. Because of less precipitation in the early stage, snowfall is very beneficial to alleviate drought and agricultural production. However, the continuous rainy weather in the southern region will affect the growth of crops to a certain extent.

　　The global climate is closely related, and El Ni? o "adds fuel to the fire"

　　Looking around the world, not only has there been precipitation in many places in China recently, but there have also been frequent snowstorms in Europe and the United States.

　　Chen Lijuan pointed out that Europe, influenced by the Atlantic warm current, belongs to a temperate maritime climate, and the water vapor conditions are still abundant in winter, which is favorable for precipitation. If cold air from the polar regions moves southward, it is easy to form snowfall. Influenced by the water vapor transport conditions in the western Atlantic Ocean and the eastern Pacific Ocean, the United States is also prone to heavy snowfall when it encounters strong cold air activities. From January 26 to 30, the polar vortex invaded the United States southward, and two-thirds of the United States suffered from extremely cold weather, and the temperature dropped to the lowest in many years.

　　She said that from the global climate background, since September 2018, the tropical Middle East Pacific has entered an El Ni? o state, which will form an El Ni? o event, which is conducive to transporting more tropical ocean water vapor to the southern United States. El Nino event has no direct contribution to the cold wave in North America, but when the cold wave occurs, if more water vapor is transported to the mainland of the United States, it will easily lead to heavy snowfall, thus aggravating the disaster and influence of cold wave activities.

　　At the same time, when El Ni? o occurs, it is beneficial to transport more water vapor from the western Pacific Ocean and the South China Sea to China’s land areas, creating conditions for precipitation in the eastern part of China, and cooperating with the process and intensity of cold air activity in the middle and high latitudes, causing rainfall or snowfall in different parts of China.
