The class teacher drew a super cute pinyin table, but half the students in the class had finished learning pinyin in advance.

  The summer vacation is about to return to zero. These days, not only students who have not finished their homework, but also novice teachers who are about to take over the first batch of students in their lives are in a state of intense preparation. For the new semester that will start soon, their hearts are both looking forward to and uneasy.

  Jiang Li, a teacher at Dinglan No.2 Primary School in Hangzhou, went to Qianbao reporter to tell her recent distress. Because Mr. Ding found that the "opening gift" that he started preparing for freshmen early may not be used.

  It is a difficult problem for freshmen to learn pinyin.

  She racked her brains to think of a way.

  Teacher Jiang is a post-1995, who just joined this year. After the new semester begins, she will be the Chinese teacher and head teacher of Class 1 (5) in the school.

  Because he is a novice, this summer vacation, Mr. Jiang has almost no rest and has been preparing for the new semester. Nowadays, all primary schools advocate zero-based admission, regardless of pinyin or literacy, they begin to learn after entering primary school. Therefore, when preparing lessons, Mr. Jiang thought a lot of countermeasures for the problems that zero-based students often encounter when they are beginners.

  "For children in grade one, pinyin is very difficult to learn. Because letters are too abstract for them, it is difficult to establish a connection between letters and pronunciations, and many letters with similar shapes and sounds are easily confused. " Teacher Jiang said.

  This summer vacation, she has been thinking about pinyin. How can we help children learn pinyin effectively?

  Not long ago, when practicing the standard writing of pinyin, Teacher Jiang had an epiphany and came up with a way — — Hand-drawn cartoon pinyin table.

  "In math textbooks, in order to let children remember the writing of numbers, each number will be integrated into cartoon pictures. Pinyin and numbers are abstract symbols. If pinyin letters are also integrated into cartoon patterns, they may have the same effect. " Teacher Jiang explained.

  After having an idea, she immediately started to work and spent an hour to finish the preliminary drawing of the cartoon pinyin table. On this pinyin table, some common animals or articles are painted, and one or two pinyin letters are "inlaid" in each pattern. "Now this is just a sketch. I’m going to ask the art teacher for help to further beautify and simplify the pattern, and then use it as a teaching tool for students to consolidate their knowledge and expand their thinking." Teacher Jiang said that she also considered letting students draw together, and the "mosaic" way of patterns and letters was designed by the students themselves.

  I have to say that this is a very creative idea. Adding vivid teaching methods such as pictures, jingles and finger dancing to the classroom can help junior children enjoy the class more quickly and develop their imagination.

  However, Mr. Jiang soon found that his "opening ceremony" carefully prepared for the students was probably not used.

  More than half the students in the class.

  I finished learning pinyin in advance.

  "I know that some students will definitely learn Pinyin in advance during the summer vacation, but the proportion should not be too large, and even if they want to learn, they will not learn it systematically." Teacher Jiang said.

  These two days, she made a home visit to the students in her class, and this idea was completely subverted. "I found that more than half of the students in the class have almost finished learning Pinyin in advance." During her home visit, she specially brought her textbooks to check on the spot. Many students who have studied pinyin have mastered the most difficult polysyllabic pinyin and can basically spell it freely.

  "I can understand the anxiety of parents who are afraid that their children can’t keep up with the start of school, but every teacher will prepare lessons according to the progress of the class before class. Such advanced learning will disrupt the teacher’s teaching plan." Teacher Jiang said helplessly. In her opinion, such advanced learning is not necessarily good for children.

  "In class, I will abide by the barrel principle and take students who have not mastered pinyin as the standard. I will not give up those who have not learned because most people have learned it." Teacher Jiang said. Moreover, during her home visit, she found that many students’ pronunciation was not standard when they were receiving off-campus training because the teacher didn’t teach them seriously. After all, Pinyin is the most basic thing in Chinese learning. If there are mistakes at the beginning, it will be more difficult to correct them later, which will also have a negative impact on children’s future study.

  After discovering this problem, Mr. Jiang was busy again, and the lesson plans that had been prepared for more than half a month needed to be readjusted.

  "In the past, preparing lessons was based on zero-based children. Now we need to redesign the way of class according to the differences in students’ learning level." Teacher Jiang said. In the future teaching, she will pay more attention to students with zero starting point and cultivate their interest in learning as soon as possible. For those children who have learned pinyin, she will pay attention to their learning methods and spelling methods, and get rid of some incorrect places, so that they can apply pinyin to Chinese learning as soon as possible.

  "You can also let the children who have learned Pinyin study with other children to form a good learning atmosphere." Teacher Jiang said. (Reporter Jianwei Liang correspondent Chen Hongcheng)

Billion-level market is worth deep cultivation.

When choosing the target of agency products, its market depth and breadth are one of the most important considerations.

According to statistics, the national personal care market has an annual market size of about 80 billion yuan. Electric shaving, which is known as the "king of personal care", is the most important category, with a market size close to 30 billion yuan. With the development of industries and sub-categories, the new demands of consumers are constantly being met, and the market scale is still growing.

Category innovation hits the blue ocean of the market directly

No matter domestic or foreign brands, they have not upgraded their products for more than years, and they are clumsy in size, outdated in appearance and traditional in art, and generally make batteries/power cords/special charging stands inconvenient to carry and use every day.

In 2017, Xiaomi Eco-chain enterprise Xumei Technology was founded, and the "debut" product Mijia ultra-thin portable shaver, the pre-sale sales exceeded 40,000 units, and the sales in that year exceeded 500,000 units. This product is not only compact, but also the first to be equipped with a Type-C charging port. Since then, the category of "portable shaver" has been formally established in the market, and the Type-C charging port has been gradually applied to some razors.

Distinctive competition with distinctive characteristics

Traditional razor brands have been in the market for many years, and it is difficult for new brands to compete with them. Beard shaver focuses on the characteristics of "fashion and portability", which is different from traditional categories in product positioning, scenes and attributes, and specializes in "the second knife for men" and the personality choice of the next generation of youth. When people think of razors suitable for travel, or young people want to find different choices from their parents, beard shaver can make everyone shine.

Up to now, more than ten products have been launched in two series. Almost every one comes standard with IPX7 waterproof, all-metal body, Type-C charging, long battery life, boot protection and other functions. It has won many awards and is also loved by consumers. Among them, the T3 series of beard turbine shaver alone has created sales of 300 million.


Own factory, deep research and development

Unlike the "online celebrity" brand that has sprung up in the market in recent years, Xumei Technology is also a research and development enterprise with its own factory. It is a rare razor brand with complete self-developed reciprocating razor technology in China.

Because of the high research difficulty and large investment, reciprocating shaver has always been synonymous with the high-end shaver market. Some international brands of reciprocating shavers cost three or four thousand yuan at a time, and Xuman Technology has filled the gap in domestic reciprocating shavers and pulled the unit price of its products within one thousand yuan. With the improvement of people’s consumption power, the market share of reciprocating razors is rising, and opportunities are gradually emerging.

Tengshi N9 declaration information exposure vehicle length is over 5m 2 and wheelbase is over 3m 1.

After the flagship of MPV and sedan, the flagship of brand SUV is coming. After many spy photos were exposed, Tengshi N9 boarded the latest new car declaration catalogue of the Ministry of Industry and Information Technology.

As can be seen from the declaration, the overall design of Tengshi N9 is still very imposing, and the closed front face is not monotonous. There are C-shaped decorations on both sides of the front of the car, and a trapezoidal air inlet with a small area is left at the bottom of the front bumper. The side lines of the car body are relatively straight, but there is a curve that fits the wheel arch before and after, which makes the huge car body more harmonious. The rear part of the car is designed to be relatively full, and the taillights and high-position brake lights are designed in long strips, but they are not connected through.

Of course, there are different opinions about the appearance of Tengshi N9, but as a flagship model, it is not a bad thing to be more mature and stable. Moreover, the electronic exterior rearview mirror and the lidar on the roof highlight the scientific and technological attributes.

In addition, the detailed body dimensions are provided in the application information. The length, width and height of Tengshi N9 are 5258mm/2030mm/1830mm respectively, and the wheelbase reaches 3125mm, which is at the same level as that of Hehe. However, the curb weight of Tengshi N9 exceeds 3.1 tons, which is much heavier than that of the M9 and the ideal L9. The declared model adopts a six-seat layout.

In terms of power, Tengshi N9 will be equipped with a hybrid system consisting of 2.0T engine and 3 motors, in which the maximum power of the engine is 152kW, the maximum power of the front motor is 200kW, and the maximum power of the two rear motors is 240kW respectively. Therefore, although Tengshi N9 has a huge body, its dynamic performance is also very strong, and its maximum speed can reach 230 km/h. In addition, Tengshi N9 will be equipped with a group of 46.992kWh, with a pure battery life of 165km.

Zhao Changjiang, general manager of Tengshi Sales Division, once said on social media that Tengshi N9 will be an SUV that peers can’t catch up with in five years. Therefore, in addition to the oversized body size and easy three-way technology, Tengshi N9 may have more functions and configurations worth looking forward to.

Telephone flow, material supply … Nearly 1,000 young volunteers in Chaoyang District support epidemic prevention and control.

Chang Kai, a takeaway rider, recently changed his post. He parked the takeaway electric car, left his small home, dragged a big suitcase full of laundry, and joined the "Youth Guarantee Commando" in Chaoyang District to become a volunteer. In a warehouse in Sunhe Township, he skillfully packed protective clothing, masks, gloves and other epidemic prevention materials and distributed them to the "Dabai" who worked in the control area.

 

Since the current epidemic in Beijing, there are still many volunteers from all walks of life like Chang Kai fighting in the front line of epidemic prevention, including social workers, real estate agents, take-away riders, and courier brothers … The reporter learned from the Chaoyang Youth League Committee that three youth epidemic prevention volunteer service teams have been set up, including the youth insurance commando team, the community bayonet supervision service team and the migrant volunteer service team. As of November 17th, Chaoyang Youth League Committee recruited 979 young volunteers from 26 volunteer teams to participate in epidemic prevention and control through socialization of various youth communities.

Material support point: takeaway riders should contribute to epidemic prevention.

 

Chang Kai has a WeChat group named "Beautiful Chaoyang Knight". The group friends are all courier brothers and takeaway riders from Chaoyang District who have won the title of "Beautiful Chaoyang Knight". The group often forwards notices of public welfare activities, and Chang Kai always takes an enthusiastic part as long as he has time.

On the evening of November 10th, Chang Kai suddenly saw a message in the group that Chaoyang Youth League Committee had called volunteers to support this round of epidemic prevention and control. "In the last round of the epidemic, I also signed up as a volunteer. At that time, I was a’ big white’ in a community in Wangjing Street. So when I saw the recruitment notice on the evening of the 10 th, I signed up without hesitation. " In 2018, Chang Kai came to Beijing to become a takeaway rider. In his view, the rider’s specialty is that he is very familiar with the streets and lanes, and the efficiency of receiving goods is high. "It is indispensable to participate in the prevention and control of the epidemic. This is my specialty. I must sign up."

 

Simply packed up and changed clothes. At 2 pm on November 11th, Chang Kai and several other volunteers arrived at the material support point. This is a warehouse temporarily converted from a gym in Sunhe Township, Chaoyang District. Volunteers divide the gym into No.1 warehouse and No.2 warehouse according to the area, in which No.1 warehouse stores protective clothing, and No.2 warehouse stores masks, screens, gloves, etc. These materials are neatly stacked on the wall according to different categories. Loudspeakers are also stored on the shelves of the warehouse, which are also good helpers for "Dabai" to work in the control area.

 

Every morning is the busiest time for volunteers. They have to distribute the materials to Dabai in the control area according to the quantity on the form. In order to avoid mistakes in busy work and improve the efficiency of distribution, Chang Kai and his colleagues divide the work of "dispatching". "For example, I am responsible for distributing protective clothing, and the other two colleagues are responsible for distributing masks and gloves, which is fast and not easy to make mistakes." Chang Kai said.

 

After the "morning rush", the pace of work of volunteers slowed down. However, Chang Kai, who is restless, always goes to the volunteer leader of the security point for work, either cleaning the warehouse again or checking the inventory with the material list. During the epidemic, many caring units donated epidemic prevention materials, which also need volunteers to classify and transport them to the warehouse for storage.

 

"If doctors and nurses who directly face infected people are regarded as the’ first post’ of epidemic prevention and the’ big white’ of the community is the’ second post’, then our volunteers are the’ third post’. Each of us is like a link in the’ chain’, and no one can drop the chain, but we must twist it into a strength and rush forward. " From November 11th to today, Chang Kai has been working in the security point for a week. "I will continue to be a volunteer. I want everyone to know that our takeaway riders will not only deliver food, but also do good public welfare and contribute to epidemic prevention."

 

In the closed control area of Chaoyang District, there are also volunteers. Guo Lingjiang, deputy secretary of the Communist Youth League Committee of non-public enterprises, has participated in many public welfare emergency distribution activities. In this epidemic, he called on riders to join the volunteer team to provide material distribution support for the closed control area of Anzhen Street.

 

It was not easy at first, Guo Lingjiang told reporters, "Some riders were unable to take orders because of the pop-up window, and there was a shortage of capacity." What if there are not enough hands? Guo Lingjiang’s company is a take-away food delivery enterprise, so he held an emergency meeting with his colleagues to find ways to optimize the transportation capacity and deploy human support from other areas such as Haidian. In the end, it not only provides voluntary service for material distribution in the closed control area, but also ensures the daily distribution needs of citizens.

 

At present, Guo Lingjiang has called on more than 50 young people to join the volunteer team. "We are ready, and we will rush up as soon as necessary." Guo Lingjiang said.

"44th Street": Do a good job of telephone flow, and don’t add chaos to the community.

 

There are 43 townships in Chaoyang District, but there is a "44th Street" in Baiziwan. In this special "street", about 50 volunteers form a youth volunteer service team by telephone to provide strong support for epidemic prevention and control in townships.

Speaking of the origin of the name "44th Street", Yang Jie, a social worker of the Community Youth Exchange, said with a smile: "We 50 people come from 43 townships in the whole district, so we simply named our service team" 44th Street ".

Volunteer Yang Jie (right) and her colleagues are making a phone call. Photo courtesy of respondents

In order to do a good job in telephone streaming, Chaoyang Communist Youth League set up a hotline call platform for 48 hours, giving full play to the advantages of social mobilization, coordinating the Youth League Committee of Chaoyang District Lawyers Association to provide site and workstation support, and coordinating the enterprises where the Youth League Committee members are located to set up a call center platform. The second-level non-governmental organizations also sent volunteers a public lunch.

 

Telephone traffic control is an important part of epidemic prevention and control. Yang Jie is an old traffic control volunteer, so in this volunteer service, she is mainly responsible for teaching the technical essentials of telephone traffic control to "novices" and filling in the traffic control form accurately as required.

 

Making a phone call seems to be a simple job, but it requires patience and meticulousness. Yang Jie said: "In the list we got, some people may need to stay at home for seven days, while others may need three days and two inspections. The situation is not the same. Moreover, some people in the form don’t have addresses in Beijing, so we have to ask carefully when doing the flow adjustment to confirm their specific addresses in Beijing, so that we can accurately feedback to the community. " Recently, the volunteer service team has increased its manpower, and everyone is divided into four groups to carry out telephone streaming. Every day, when colleagues finish the task of flow adjustment, Yang Jie always checks these lists again to see if there are any omissions.

Yang Jie worked as a volunteer in Chaoyang District CDC before. Compared with the last experience, she felt that the pressure was even greater this time. "The last time I worked with the teachers of the Center for Disease Control and Prevention, I could ask questions at any time. I always felt that the teachers could give us the bottom, and I was practical. This time, I am the team leader and also responsible for training. Without a disease control teacher around, I dare not have any omissions in my work. We must not add chaos to the epidemic prevention and control in the streets and townships because our work is not in place. "

 

The reporter learned from the Chaoyang Youth League Committee that the volunteers came from many caring enterprises in Chaoyang District, as well as universities such as Beijing Information Science and Technology University, university of international business and economics and beijing international studies university. In order to strictly abide by the epidemic prevention regulations of colleges and universities, college volunteers are currently conducting online volunteer service.

 

Community bayonet: real estate agents become health code inspectors, and residents give thumbs up.

These days, real estate agent Ding Guanghui runs the community more frequently.

"When I don’t take customers to see the house, I often run to the community, and I have to check whether the QR code of the bayonet meets the requirements." Ding Guanghui told reporters that after the current epidemic, he signed up for the "community bayonet supervision service team", whose main task is to check whether the community has achieved "one bite and one yard".

Before taking up his post, Ding Guanghui participated in online volunteer service training and realized the importance of "one bite and one yard" for accurate epidemic prevention and control. Therefore, after becoming a volunteer, Ding Guanghui regularly goes to the bayonet of each community, scans the QR code of the bayonet with his own health treasure to check whether it is normal or not, and then uploads the scanned code results to the information platform through the mobile phone.

 

Real estate agents and many residents in the community are old friends. When Ding Guanghui came to "scan the code", the neighbors in the neighborhood could not help but exchange greetings. Familiar uncles and aunts gave him thumbs up, and residents who used to buy real estate through Ding Guanghui even pulled him to chat. Ding Guanghui is very happy, because this job has been understood and cooperated by the residents, and he is more energetic as a volunteer.

This year is the first Spring Festival travel rush after the successful application for World Heritage during the Spring Festival, and it is also the Spring Festival travel rush with an 8-day Spring Festival holiday. "The demand for travel such as visiting relatives and traveling will be further stimulated, and the passenger flow in Spring Festival travel rush will continue to grow on the basis of last year’s high base." Yang Zhusong, an associate researcher at Tsinghua University Institute of National Studies, said.

China has made joint efforts from many places and departments to ensure a convenient and warm trip to Spring Festival travel rush. Beijing railway station improves the way of passengers entering and leaving the station and improves the traffic efficiency; Shenzhen North Station cooperates with China Railway Express and Shenzhen Airport to set up service points. Passengers can check in and check their luggage immediately after getting off the high-speed rail.

The high-speed railway with a mileage of 48,000 kilometers is the main force in Spring Festival travel rush. In 2024, a new high-speed railway line of 2,457 kilometers was put into operation in China, making it more convenient for passengers to travel in Spring Festival travel rush.

In shanghai hongqiao railway station, Wang Qinran’s family took the G1627 train back to their hometown of Huzhou to visit relatives and have a holiday. The Shanghai-Suzhou-Lake high-speed railway connecting the Yangtze River Delta was opened at the end of 2024, and it only takes about one hour to return to Huzhou from Shanghai. "Not only is the driving time reduced by half than before, but the number of optional trains has also increased significantly. Spring Festival travel rush is very comfortable this year. " Wang Qinran said.

In 2025, self-driving travel will occupy the main position in Spring Festival travel rush, and it is estimated that the scale of cross-regional self-driving travel will reach 7.2 billion. With the successful application for the World Heritage in the Spring Festival, it has become a new year’s way for many people to bring their families to go on road trip and experience different folk customs in different places. According to the data of Zhongxin Tourism Group, the number of people traveling in the Spring Festival in 2025 is expected to increase by 46%.

Guo Wei and his family drove north from Tangshan, Hebei Province. On the first day in Spring Festival travel rush, he arrived in Fuxin, Liaoning Province to experience folk tourism. He was very interested in local activities such as paper-cutting and posting Spring Festival couplets.

"The successful application for the World Heritage has added a special flavor to the Spring Festival." Guo Wei said that his trip to Spring Festival travel rush will continue in the next few days. "We plan to drive all the way to Harbin to deeply experience the folk customs of the Spring Festival in Northeast China".

Influenced by favorable factors such as the new policy of 240-hour visa-free transit and the increase of entry and exit ports for visa-free transit personnel, the popularity of "China Travel" has not diminished, and more and more foreign faces have appeared in the "Spring Festival travel rush Army". According to a report by Ctrip, the number of foreign tourists’ travel orders in China in the Spring Festival of 2025 increased by 203% year-on-year.

Polish tourist Magdalena and his family were waiting at Shanghai Pudong Airport on the 14th, preparing to fly to Shenyang to start a trip to Northeast China. In the next few days, they will also take the high-speed train to Anshan and other places.

"I have heard of Spring Festival travel rush in China, and it feels very special to catch up this time. You can enjoy the beautiful scenery along the way, appreciate the folk customs and have a different experience." Magdalena said.

Foreign media are worried that "killing robots" will move towards autonomy and urge the introduction of bans to restrict research and development.

The reference news network reported on December 17. The US media said thatWeapons that can kill people without direct human participation, the so-called "lethal autonomous weapons" will soon appear.

According to the US Forbes biweekly website reported on December 15, on September 14, 2019, a small number of drones attacked the Hureis oil field and the Bougueg refinery in Saudi Arabia. In addition to disrupting 5% of the world’s crude oil production, the attack also highlighted some challenges brought by the use of these remote-controlled weapons.

The report said that the first is that it is difficult to be accountable. Nearly three months after the incident, it is still unclear who made the attack. Like hackers in cyber warfare, the attackers left almost no trace. Another problem is that such weapons are small in size and relatively low in cost, so they may be attractive to a small group of militants or terrorists and some countries.

The report said that this is scary enough. However, in view of the current development direction of the arms industry, these concerns cannot be compared with those that may arise in the future.

As the Dutch NGO "Peace" pointed out in a report published a few weeks ago, the world is on a dangerous path, and those weapons that can kill people without direct human participation, the so-called "lethal autonomous weapons", will soon appear. The more common name of this kind of weapon is "killing robot".

According to the report, this nickname is misleading to some extent, reminiscent of fantasy things such as "Terminator" in science fiction movies. In fact, these tools are similar to more traditional deadly devices: unmanned combat aircraft, tanks, submarines; What has changed is not the shape of the weapon, but its degree of autonomy. At present, completely autonomous offensive weapons have not been deployed in actual combat, but machines are becoming more and more advanced, and the dependence on human control is decreasing.

One example is the "Cargou" autonomous attack four-axis UAV developed by the Turkish state-owned enterprise STM. According to reports, it will be deployed in the border area adjacent to Syria in eastern Turkey in 2020. According to an article in the Turkish newspaper Freedom, each "Cargou" fleet will consist of 30 drones, all of which are equipped with artificial intelligence and facial recognition systems. Depending on the coordinates or images of the target, these Cargou UAVs will be able to complete all tasks autonomously. Fortunately, human operators can still choose to "abort the mission" and "return to the base" at all stages of the drone attack.

According to the report, Russia’s T-14 Amata main battle tank is equipped with unmanned turrets and computerized systems, so it is often regarded as another equipment case that will soon achieve complete autonomy-although some people doubt whether this will really make it more effective on the battlefield.

Perhaps not coincidentally, countries such as Russia, Israel and the United States strongly oppose banning the development of "killing robots" in advance. The United Nations discussed the issue of pre-banning such weapons at a meeting in Geneva in November.

As The New York Times pointed out in a recent special report, the measures to ban blinding laser weapons in advance were successful. Therefore,Theoretically, this ban may also apply to "killing robots". The general public awareness and strong support for the ban may change the situation, which is what is missing at present.

[Extended reading] Lifting the ban on "killing robots"? The US military AI development strategy involves ethical disputes.

The reference news network reported on February 15. According to the British "Daily Mail" website reported on February 14th, the US military hopes to expand the application of artificial intelligence (AI) in the war, but said that it will pay attention to the deployment of this technology according to national values.

According to the report, in a 17-page report, the Pentagon explained how to inject artificial intelligence into future military operations and how to keep up with the technological progress of Russia and China in the future.

The report entitled "Using Artificial Intelligence to Promote Our Security and Prosperity" marks the first time that the Pentagon has formulated a strategy on how to deal with the rise of artificial intelligence.

The strategic plan calls for accelerating the use of artificial intelligence systems in the whole army and carrying out a series of tasks, from intelligence gathering actions to predicting maintenance problems of fighter planes or ships. It urges the United States to rapidly advance such technologies before they are weakened by other countries.

"Other countries, especially China and Russia, are also investing heavily in artificial intelligence for military purposes, including those applications that have been questioned by the outside world in terms of international norms and human rights," the report said.

The report makes little mention of automated weapons, but quotes a military directive in 2012 that requires manual control. A few countries, including the United States, have been obstructing the international community from setting a ban on "killing robots" at the United Nations. One day, this completely autonomous weapon system may wage war without human intervention.

The United States believes that it is too early to try to regulate "killing robots".

The report believes that the strategic report released by the Pentagon this week focuses on more immediate applications, but even some of them have triggered ethical debates.

After Google’s internal protests led the technology company to withdraw from the Maven project last year, the Pentagon encountered obstacles in the field of artificial intelligence. Maven project is to analyze aerial images of conflict areas by using algorithms.

Other companies are trying to fill this vacuum, and the Pentagon is working with artificial intelligence experts in industry and academia to formulate ethical guidelines for their artificial intelligence applications.

Todd Probert, vice president of artificial intelligence department of Raytheon, said: "Everything we see is decided by human decision makers."

Probert said: "The project is using technology to help speed up this process, but it has not replaced the existing command structure."

[Extended reading] Expert warning: Killing robots may lead to an arms race or lead to the massacre of civilians.

The reference news network reported on November 21. The British "Star Daily" website published a report entitled "The Killing Robot Arms Race" on November 17th.

An artificial intelligence expert revealed that the United States, Britain, Russia, Israel and other countries are involved in a competition to build a killing robot army.

From self-shooting guns and drones to remote-controlled super tanks, prototype robots in the United States and Russia have been successfully built and ready to go. And humanoid robots on the battlefield will only appear in a few decades-and outline a terrible prospect for the world.

Noel sharky, honorary professor of artificial intelligence and robotics at the University of Sheffield in the UK, told SciDev.Net: "An arms race has begun."

Sharky said: "What we are seeing now is that the United States, Israel and Russia (the killing robot arms race) has begun. If these things appear, then they may accidentally trigger war at any time. "

He also said: "How can we ban them? You can put these things on hold forever, but they only need to be recharged to start again. "

Nowadays, artificial intelligence robots are setting off a craze around the world. Professor sharky is worried that the research and development of killing robots may also have such an amazing speed. Therefore, he is leading a global movement to ban killing robots.

After this website disclosed the latest development-American robots do backflips-the expert warned that the latest project in Russia was "absolutely frightening".

Sharky said: "There is something terrible … The Russians have developed this thing called’ super tank’, and it is the most advanced tank in the world, which is much ahead. It is definitely a monster with great destructive power, and they can remotely control it. They are still trying to turn it into a fully automatic robot at the fastest speed. "

Although autonomous armed robots are ahead of humanoid robots for many years, Professor sharky is worried that the possible humanoid robots may bring disaster to the world-leading to the massacre of civilians.

When warning about the terrible consequences of killing robots, Professor sharky said: "This can’t be in line with the laws of war. Can they distinguish whether a target is a military target or a civilian target? This is the key to the law of war. "

He said: "It is also not allowed to kill people who try to surrender. I know that many people think that surrender means raising a white flag, but actually surrender means any gesture that shows that you are no longer fighting, such as lying on the ground unarmed … but robots can’t distinguish this. My biggest personal concern is what kind of damage this will cause to global security-because an arms race for such weapons has already begun. "

[Further reading] German media said that the United Nations wanted to restrain the development of "killing robots" so far without results.

The reference news network reported on November 16. According to the German Daily Mirror website reported on November 13th, in the near future, completely autonomous killing robots will decide people’s life and death on the battlefield. Discussions on prohibiting or at least restricting the use of such weapon systems have not stopped in recent years, but so far there is no result. The United Nations recently began discussions on this issue in Geneva.

What is a killing robot?

Its official name is "lethal autonomous weapon system". At present, there is no universally valid definition. The United Nations and the International Red Cross explain it this way: it can set targets, launch attacks and clear targets without human help. In other words, once programmed, these weapon systems can independently analyze data, navigate to the combat area and use weapons such as cannons or rockets. In recent years, the great progress in the field of artificial intelligence constitutes the basis for the development of killing robots.

The drone that is already in use is still controlled by soldiers, so it is not a killing robot. Although it doesn’t seem far away from its independent operation.

How far has it developed?

Russian Deputy Prime Minister rogozin, who is in charge of armament, released a video this spring, in which a humanoid killing robot like Terminator can be seen. This is more of a propaganda category. It doesn’t matter whether the appearance is similar to that of human beings. Experts from Human Rights Watch believe that "the autonomy of weapon systems developed by the United States, Britain, China, Israel, Russia and South Korea is increasing". At present, there are already prototypes in use.

Supporters argue that it will minimize the danger of soldiers. But this may lead to the lowering of the threshold and the increase of wars-thus leading to more civilian casualties. People can already see this development in the use of remotely controlled drones.

The picture shows a military drone equipped in the United States.

Who will bear the consequences?

This is a fundamental ethical issue that is inseparable from the killing robot. Ethical and moral actions, the distinction between good and evil, right and wrong, the evaluation of the consequences, and the responsibility for one’s own actions all do not exist in future wars. Although the robot has artificial intelligence, it has no feelings such as pity or regret, and it has no sense of guilt. It has no way to start with concepts such as moderation. But this is written in the so-called law of war: the parties to the conflict must avoid unnecessary damage and unnecessary pain to each other. We must be kind to civilians, injured, incapacitated and captured soldiers. Experts believe that this cannot be programmed. In 2013, policy experts warned in a report to the United Nations Commission on Human Rights that these "tireless war machines" may turn armed conflicts into endless wars-diplomacy will not be able to stop the killing of machines dedicated to fighting even if there is no hope.

How to establish legal norms?

So far, no. This UN conference will not legislate, but will only explore its political, ethical and legal space in a "political statement". A ban is out of the question.

Since these systems do not actually exist at present, Germany and France propose to define autonomous weapon systems first. A group of technical experts, including military representatives, will explain the risks of new weapons. The representative of the "International Campaign to Stop Killing Robots" thinks that this is not enough, and these weapons must be banned in advance.

Only 19 countries have asked for a ban. Behind the scenes, it is precisely the countries that are leading in integrating artificial intelligence with combat equipment. Recently, more than 100 experts wrote in an open letter that killing robots are the third combat revolution after gunpowder and nuclear bombs. If new weapons fall into the hands of tyrants and terrorists, what awaits people will be complete terror.

More than 8 models of Tiggo were exposed to brake failure, and the problem pointed to brake by wire!

If you are the owner and prospective owner of Tiggo 8 PRO or Tiggo 8 PLUS, please note that there is something wrong with Chery’s brake-by-wire technology.

Recently, Master Jiao learned from relevant channels that Chery’s brake-by-wire technology has brought troubles to many car owners. The specific performance is as follows: 1. There will be a buzzer when braking; 2. The brake pedal becomes hard; 3. Brake failure; 4. Brake jitter. At present, it is understood that some car owners have formed rights protection groups and shared fault cases in the groups.

Please step on the brakes when the vehicle starts, but the owner has been stepping on the brakes.

The corner master found that a car owner was driving at a low speed of 30 kilometers per hour, and suddenly the brake pedal rebounded, and then a fault code appeared in the dashboard. At this time, the brake pedal felt hard and the hard-vegetable pedal vehicle appeared jitter.

At present, the official has not responded to this problem, and the owner has locked the root of the problem in the brake-by-wire technology. Because some owners of Tiggo 8 PRO and Tiggo 8 PLUS do not have such problems, the problem owners are mainly concentrated in the vast version of Tiggo 8 PRO and Tiggo 8 PLUS pride+,so what is Chery’s brake-by-wire technology?

In March 2022, Chery Automobile announced a major innovation when it launched the Tiggo 8 PLUS version. The braking system of the car was upgraded and the integrated brake-by-wire system of Bethel WCBS was adopted. The core technology of this system is to integrate the vacuum booster pump, master cylinder, electronic vacuum pump, EPB and ESC. The following figure shows the comparison between the integrated brake-by-wire system module and the traditional vacuum booster pump. Its main purpose is to reduce costs and enhance the competitiveness of products. In addition to cost reduction, the official said that this system can also coordinate energy recovery system and high dynamic pressurization capacity. In other words, most of Chery’s new energy vehicles will adopt the brake-by-wire system in the future.

Integrated brake-by-wire system

Traditional vacuum booster pump

However, at present, it is obvious that the technology is not yet mature, and some car owners equipped with brake-by-wire technology have become "mice". Master Jiao then went to the domestic third-party vehicle quality complaint platform to investigate and found that there have been centralized complaints about the models equipped with brake-by-wire technology in the Tiggo 8 PRO plate, and the most complained car in the Tiggo 8 PLUS plate is Haoqing+,which is also equipped with brake-by-wire technology.

Up to now, Chery officials have not responded to the vehicles with problems in the by-wire control technology. Judging from the problem of concentrated outbreak, Master Jiao’s personal guess may be that there is a problem with a batch of vehicles equipped with wire control technology. The failure of the brake system is a major personal safety hazard, and the manufacturer must attach great importance to it, and it is necessary to complete the upgrade, optimization and even recall of the problem model in a short time.

A few days ago, Chery Automobile just released the sales data in July 2022, and the group’s sales volume was 131,533, a year-on-year increase of 57.7%. This figure successfully surpassed 122,633 vehicles of Geely Automobile and 101,920 vehicles of Great Wall Motor. In terms of splitting, Chery’s total sales volume was 131,533 vehicles, of which 50,614 vehicles were exported, up 90.1% year-on-year. The sales volume of new energy was 25,614 vehicles, a year-on-year increase of 253%. It can be seen that the sales of new energy have surged, and in addition, the export volume has reached a new high. This is the happy side.

However, the safety hazard brought by the brake-by-wire technology hangs over Chery like a time bomb. However, if it is detonated, it will surely face the collapse of product quality reputation, and all efforts will be wasted.
