Xinhua News Agency, Beijing, May 24 (Reporter Qi Qi) the Supreme People’s Court issued the Interpretation of the Supreme People’s Court on Several Issues Concerning the Application of the Limitation System in the Trial of Judicial Compensation Cases on May 24, fully protecting the legitimate rights and interests of compensation claimants and unifying the understanding and application of the limitation system for requests. This interpretation shall come into force as of June 1, 2023.

　　According to reports, the judicial interpretation consists of thirteen articles, the main contents of which include the starting rules of the limitation of criminal compensation claims, the starting rules of the limitation of non-criminal judicial compensation claims, and the deduction rules of the special period of the limitation of claims. Based on the reality of judicial compensation, the above provisions fully consider whether there are factual obstacles and legal obstacles when the claimant applies for compensation, reasonably determine the starting date of the limitation of claims, and make it clear that the compensation Committee of the people’s court shall not actively apply the limitation of claims in the trial of state compensation cases, thus solving some controversial difficulties in the application of law and effectively implementing "fairness and efficiency".

　　"There are different understandings about whether the limitation of judicial compensation request is substantive limitation of action or procedural limitation of prosecution in nature." The person in charge of the the Supreme People’s Court Compensation Commission Office introduced that after in-depth investigation and extensive solicitation of opinions from all parties, a consensus was reached on this issue. It is generally believed that the limitation of judicial compensation claims is in nature a statute of limitations. After the expiration of the limitation period, the rights of compensation claimants are not protected by law, but the rights of compensation claimants are not eliminated. Accordingly, the judicial interpretation stipulates that "after the expiration of the limitation period for claims, the organ liable for compensation agrees to compensate or make compensation, and then raises a defense on the grounds of the expiration of the limitation period for claims or requests the claimant to return the compensation, the compensation committee of the people’s court will not support it."

　　On the basis of clarifying that the limitation of claim is the limitation of action in nature, the judicial interpretation stipulates that the organ liable for compensation has the right of defense against the limitation of claim, that is, "when the limitation of claim expires, the organ liable for compensation may raise a defense against compensation". However, if the organ liable for compensation agrees to pay compensation or has paid compensation after the expiration of the limitation period, and then raises a defense or requests the claimant to return the compensation on the grounds of the expiration of the limitation period, the compensation Committee of the people’s court will not support it.

At the room temperature of 25℃, plus the airtight protective clothing, Wang Zhaoe could feel the sweat dripping down, and a layer of fog had already appeared on the goggles.

Wang Zhaoe wrote down the sample number on the cover of each EP tube and collection column with a pen, and put it in the sample grid in strict accordance with the same position.

　　After half an hour, Wang Zhaoe took the sample out of the water bath, and Yu Hong took it and put it in the biosafety cabinet.

　　Biosafety cabinet is the most important equipment in the laboratory, and Yu Hong puts her hands into it to extract nucleic acid.

Yu Hong (left) and Wang Zhaoe have been working regularly since the outbreak. That night, the main operator was Yu Hong, and Wang Zhaoe was an assistant, responsible for sample checking and centrifugation.

　　Win the epidemic prevention and control war

　　After collecting samples, how was Covid-19 detected? Nucleic acid detection is an important part of COVID-19’s judgment, and everyone who is sampled has been waiting for a "verdict": whether the nucleic acid test is negative or positive. In the microbial detection laboratories of CDC at all levels, there are such a group of "virus investigators" who are burying their heads in the microscopic world invisible to the naked eye every day to find the virus. They are not in direct contact with patients, but they are trying to peel off the true face of the virus and provide scientific, effective and powerful "big data" support for the handling of the epidemic. A sample involves the overall situation of epidemic prevention and control, and they are responsible for each sample. From January 20th to now, 15 "soldiers" from the Microbiology Laboratory of Fengtai District Center for Disease Control and Prevention have been fighting for more than 40 days, 7×24 hours a week, and have tested thousands of samples … … Recently, Beijing Youth Daily reporters put on protective clothing and followed the "virus investigators" into the front line of virus detection to uncover their mystery.

　　The test results are related to personal and overall psychological pressure.

　　At 16: 00 pm on March 2, the second-level biosafety laboratory of Fengtai District Center for Disease Control and Prevention — — Outside the respiratory virus testing room, seven sample transfer boxes are stacked in a row on the ground. Some samples have just been collected by the district CDC, and some have been specially sent by local hospitals, with sputum and throat swabs, a total of 19 samples, all sealed in transfer boxes and ready to be sent to the laboratory for testing — — The owners of these samples are waiting for a verdict.

　　Covid-19 is highly contagious, and experiments must be carried out in strict accordance with biosafety standards. In the dressing room ten meters away, Yu Hong and Wang Zhaoe, virus detection technicians on duty, are working hard to change protective clothing. Their task is to extract all the nucleic acids from these 19 samples. Yu Hong has been in the Microbiological Laboratory of Fengtai District CDC for 14 years, and Wang Zhaoe is also a veteran with 9 years of work experience. The two sisters have been working regularly since January 20th. That night, the main operator was Yu Hong, and Wang Zhaoe was an assistant, responsible for sample checking and centrifugation.

　　Hat, shoe cover, disposable isolation gown, first layer gloves, N95 mask, disposable medical protective clothing, second layer gloves, disposable medical boot cover, second layer shoe cover, splash-proof isolation gown, goggles & HELIP; … Entering the laboratory means that there is a risk of exposure to the virus. Yu Hong and Wang Zhaoe check each other’s protective clothing at any time.

　　Yu Hong said, "The test results in our hands are not only related to the owner of the sample, but also to the life safety of people around him, as well as the overall situation of epidemic prevention and control. In the early days of the epidemic, the understanding of this disease was not so clear, and our psychological burden would be particularly heavy, especially when it was positive. " At this time, Wang Zhaoe joked: "At the beginning, when I was negative, I suspected that the experiment was not done well. When I was positive, I was afraid that I would be exposed." At the beginning of the epidemic, they were always in this tangled and contradictory state, so they always recalled every step they had done, whether they had done it right or not.

　　It takes nearly 20 minutes to take out the sampling tube and disinfect it at the same time.

　　After more than ten minutes of preparation, at 17 o’clock sharp, Yu Hong and Wang Zhaoe were dressed, and the reporter of Beiqing Daily also put on protective clothing and followed them through two protective doors to enter the laboratory. Next to the outer protective door, there is a transparent glass, through which Wei Xiuxia, a staff member sitting outside, can observe the internal state of the laboratory, and can meet at any time if there is an accident. On one side of the glass, there is a small transfer window through which samples have been sent to the laboratory in turn.

　　This laboratory is about 20 square meters, and the most important equipment in it is the biosafety cabinet about two meters high in the corner, which is where Yu Hong will extract nucleic acid. This biological safety cabinet only allows experimenters to put their hands into it for operation. The cabinet is equipped with a special internal circulation system and a special filter membrane, which can ensure the isolation of the air inside the cabinet from the air outside the cabinet and prevent viruses from running outside the cabinet.

　　Ready, Wang Zhaoe took the chlorine-containing disinfectant that had just been prepared and sprayed seven boxes containing samples in turn for disinfection. Open the box, take out the yellow 95 kPa sealed can, and pass it to Yu Hong after disinfection. Yu Hong has been seated in front of the biosafety cabinet. She took the jar, slowly opened the lid, took out the sealed bag, and then carefully sprayed the front and back sides of the bag with disinfectant. Through the sealed bag, you can see the throat swab and sputum samples inside. The reporter of Beiqing Daily found that it took nearly 20 minutes to take out the 19 samples from the transfer box just to completely inactivate the possible Covid-19 on the surface of each layer of sample packaging.

　　At room temperature of 25℃ and protective clothing, sweat dripped down.

　　In order to prevent the virus infection from harming the experimenters, the samples should be inactivated before opening the sampling tube every time. Wang Zhaoe put the packed samples into a water bath pot for 30 minutes at 56℃. Later, she wrote "17: 22-17: 52" in the blank of the small card of the experimental platform to remind herself of the time. Going back and forth, getting up, disinfecting and handing samples, Wang Zhaoe’s goggles have been fogged. With a room temperature of 25℃ and a closed protective suit, Wang Zhaoe said that the close-fitting coat was soaked and he could feel the sweat dripping down his body.

　　Taking advantage of this half-hour gap, the two began another crucial preparatory work. On one side of the experimental platform, seven white sample boxes with grids have been set up. In each box, 20 white EP tubes and collection columns are placed in sequence, 19 for processing samples and 1 for negative control to ensure the accuracy of the experiment.

　　There are a total of 19 samples on the seven sample delivery sheets, and the information such as the submitting unit, the name of the sample person, whether the sample type is throat swab or sputum, and the corresponding sample number has been marked on them. The two of them wrote down the sample number on the cover of each EP tube and collection column with a pen, and put it in the sample grid in strict accordance with the same position. For example, the sample number of Wang’s throat swab is fixed to 1011, and the position of the sample box is fixed, which is fixed at the first row.

　　At this point, there are still more than ten minutes before the inactivation is completed, and the two of them are sitting in the corner to rest. "This is a closed laboratory, and wearing a N95 mask will cause great resistance, so we mostly rely on eye contact." Wang Zhaoe calmed herself down, expecting the fog on the goggles to disperse quickly.

　　The risk of removing outer packaging layer by layer increases little by little.

　　Half an hour later, Wang Zhaoe took the sample out of the water bath pot, and Yu Hong took it and put it in the biosafety cabinet, and the sealed bag was still steaming. After standing for 10 minutes, it took nearly 20 minutes to disinfect, open the sealed bag, take out the sampling tube, disinfect, mark the number and put it in the sample rack, and then all these throat swabs and sputum samples were taken out and packed neatly.

　　The outer packaging is removed layer by layer, and the risk is increasing little by little. If there is Covid-19 in the sample and it has not been completely inactivated in the early stage, then the next step is the most dangerous. Six of the samples are sputum, which must be diluted before the next treatment because it is thick. Yu Hong must first add sputum digestive juice to these six samples. She held the lower part of the sampling tube with her left hand, and the cover with her right hand. She turned the tube carefully and slowly for about three or four turns, opened the cover, added sputum digestive juice in proportion, and then covered it, allowing the sputum to stand and fully dilute.

　　Yu Hong said that although it has been inactivated, no one can guarantee whether there is any inactivated virus attached to the cover. In order to avoid the generation of aerosol, it is necessary to be cautious and the action must be small.

　　Subsequently, the sample should be moved from the sampling tube to the white EP tube dedicated for the experiment before the next cell lysis can be carried out. Gently open the cover of the sampling tube, suck 140 microliters of sample with a pipette, add it into the EP tube, and cover it. At every step, Yu Hong’s movements are very slow and careful. In her own words, "I almost can’t feel my heartbeat when doing experiments, and I can’t feel myself panting. It is a very calm state."

　　A sample is related to a life, and every step must be carefully checked. Wang Zhaoe stood on the right side of Yu Hong, holding the list in his hand. Every time he took a sample, Wang Zhaoe read the position where the sample should be packed: "Swallow swab, 1015-1, four rows; Pharyngeal swab, 1016-1, four rows and two; 1017-2, four rows and three … …”

　　Translating liquid should bypass other sample surfaces to prevent contamination.

　　To extract nucleic acid, it is necessary to add lysis solution to crack the possible virus. Yu Hong explained that this process is the process of opening the capsid of the sample virus, and all the nucleic acids in the sample, that is, DNA, RNA and other substances, are released. Yu Hong picked up the pipette, connected the suction head, sucked up part of the liquid in the EP tube containing the sample and put it back, sucked it up and put it back. After coagulation for five or six times, the liquid was more uniform. After 10 minutes, the lysis solution added to the sample has completely lysed the cells. The next step is to collect the viral RNA.

　　At this time, it is necessary to translate all the liquid in the EP tube into the collection column. The reporter of Beiqing Daily noticed that Yu Hong moved very slowly in the process of translating the liquid. When she sucked the liquid with a pipette, she deliberately bypassed the surfaces of other samples in order to prevent other samples from being contaminated. After the translation of the sample, Wang Zhaoe put these collection columns into the centrifuge in turn, and centrifuged for one minute, and all the RNA in the sample was adsorbed in the white membrane. This process has to be operated twice to completely remove the lysate and adsorb RNA on the collection membrane. Wang Zhaoe handed the extracted RNA liquid to Wei Xiuxia, who had been waiting outside the delivery window for a long time, and sent it to another laboratory for RNA amplification and detection of Covid-19. It will take another three hours, that is, it will take seven hours to know the result.

　　"Sanshan Town Demon" on the card

　　On the workbench of the laboratory, the reporter of Beiqing Daily also found a small card that read: "Demons from Vulcan Mountain, Raytheon Mountain and Sanshan Town, Zhong Nanshan, hahaha", with a monster’s head painted next to it and three smiling faces behind "hahaha". Seeing that the reporter of Beiqing Daily found this card, Wang Zhaoe rushed over to "grab" the card, buckled it on the table, and said shyly, "Oh, don’t look, this was scribbled during the last experiment." Yu Hong said that while waiting for samples, they occasionally painted on paper to pass the time and wrote these words, hoping that the epidemic would end soon.

　　After nucleic acid extraction, it is necessary to "clean up the battlefield": clean and disinfect the biosafety cabinet, clean up experimental articles and protective articles, put them into garbage bags, sterilize the desktop and floor, and turn on the ultraviolet disinfection lamp & HELIP; … They finished all the work and walked out of the laboratory, which was exactly 9 pm. Take off their protective clothing, and their faces and hands are covered with ligature marks. The skin on both sides of Yu Hong’s cheekbones has been worn red by N95 mask. When asked about her feelings, while tidying up her clothes, she said lightly, "Nothing, I have long been used to it."

　　Yu Hong had lunch at 11: 30 noon that day, and the experiment ended at 9: 00 pm, during which she didn’t eat anything. "I didn’t dare to drink more water before I went in. I was afraid that I wanted to go to the toilet and I didn’t feel hungry. My spirit was concentrated on the experiment." In order to cope with it with peace of mind, Yu Hong sent her 7-year-old son back to his hometown in Hebei before the Spring Festival. "I miss him very much and hope to see him as soon as the epidemic is over."

　　Every member of this testing team is an ordinary hero. They have a common name, which is called "Fengtai District New Coronal Pneumonia Prevention and Control Testing Technical Team". The members include: Dong Xiaogen, Qin Meng, Zhang Ling, Feng Huiru, Xing Hongguang, Yu Hong, Wang Zhaoe, Wei Xiuxia, Zhang Zhimin, Yan Tao, Meng Zhiming, Li Lijun, Cao Jiaqi, Chi Xiuping and Liu Xiaoling.

　　According to the reporter of Beiqing Daily, the sample testing in Beijing is divided into two levels in urban areas. At present, the Beijing CDC is responsible for testing some key samples, and the CDC in each district is responsible for testing the samples submitted within its jurisdiction. In addition, there are 16 hospital laboratories with detection ability in the city, which are responsible for the detection of samples in this hospital. Text/reporter Jiang Ruojing

　　conversation

　　Worried that I will affect my family.

　　I didn’t dare to enter the house for more than 40 days.

　　Dialogue: Dong Xiaogen, Chief of Microbiological Laboratory, Fengtai CDC

　　Beiqing Daily: As far as the test just conducted is concerned, are you relieved to stare at this test all the time and see the final test results?

　　Dong Xiaogen: Yes, it shows that the situation is improving.

　　Beiqing Daily: Now that machine testing is relatively mature, it can also save time. Why do you need manual testing?

　　Dong Xiaogen: Manual detection is a relatively primitive way. Machine detection is really mature, and it can be one hour faster than manual detection. However, this epidemic is urgent and fierce, and every sample is of great importance. To be on the safe side, we can use manual detection as much as possible to control every link.

　　Beiqing Daily: Apart from the COVID-19 epidemic, are other viruses usually detected manually? Will the protection level be so high?

　　Dong Xiaogen: Usually, when detecting common diseases such as norovirus, influenza virus and enterovirus, the detection methods are relatively mature. Generally, machines are used for detection, and the laboratory adopts secondary protection. But in the face of COVID-19, the epidemic situation is special, and it is a new disease. We must be responsible for every sample and our laboratory staff. To adopt the third-level protection, we must wear N95 masks and monkey suits.

　　Beiqing Daily: How did you feel when you were tested positive?

　　Dong Xiaogen: I can’t find an exact word to describe it. From the perspective of prevention and control, it can prevent proliferation, and it will be more fulfilling than the usual detection work. But I am also worried about this patient, not only about the patient’s health, but also about whether the patient will be discriminated against by people around him. As a team leader, I will also worry about my team members, especially when the epidemic just happened, fearing that they will be infected.

　　Beiqing Daily: What kind of ways will you use to ensure their safety?

　　Dong Xiaogen: I always remind them to protect themselves. Before going to work on the 20th, I specially trained them to wear protective clothing, and sent a colleague to check whether their protective clothing was up to standard every day. If it did not meet the standard, they would not be allowed to go to work. Now it is required that the working time in the laboratory should be strictly controlled at 4 hours.

　　Beiqing Daily: I heard that you just finished aiding Xinjiang and came to work before your vacation. How long have you been working in your post?

　　Dong Xiaogen: Yes, I helped Xinjiang for one year and came back on January 3rd. I could have taken a long vacation for a month, but the epidemic broke out suddenly and I came back to work on January 20. Our whole team, too, has been running around the clock since the first case was discovered in Fengtai District on January 20. Up to now, it has been 7×24 hours a week, and everyone basically eats and lives in the unit. There are 15 people in our testing team, and the samples can be tested at any time. In the laboratory, the room temperature is 25℃, wearing closed protective clothing, and the longest stay at the beginning is five or six hours.

　　Beiqing Daily: Have you been home during this time?

　　Dong Xiaogen: Because I was worried that I would affect my family, I didn’t dare to enter the house for more than 40 days, so I went back to the door of the community and took clothes twice. I stayed for less than two minutes each time, and my lover sent them to me. The last time I went back to get clothes, my wife cried when she saw me at the gate of the community. Neighbors all know about my disease control, and they deal with viruses every day. They are afraid that going home will make them worry, so they simply don’t go back and sleep in the office every day.

　　Now I dare not turn off my mobile phone every day, and I haven’t slept a good night’s sleep. I have to process information at any time, no matter day or night. I especially hope to turn it off and sleep for a few days. Text/reporter Jiang Ruojing

　　Recently, according to media reports, like most large retailers, Wal-Mart stores in the United States are planning to replace paper labels on shelves with small electronic screens, so that prices can be changed quickly and at low cost. But the conversion from paper to screen faces another problem — — The screen needs power. At present, Wal-Mart is cooperating with Osiya Company to adopt the technology of "long-distance charging", also known as "charging in the air" (Cota) to solve this problem.

　　Charging from a distance sounds amazing. What is its principle and how is it realized?

　　"Collecting" electromagnetic energy from space to realize charging

　　"Wal-Mart this ‘ Charging in the air ’ The principle of is not profound, it is ‘ Wireless charging ’ A specific application of technology. " Recently, Yan Huaizhi, director of the Institute of Computer Network and Countermeasure of Beijing Institute of Technology, said in an interview with a reporter from Science and Technology Daily.

　　Yan Huaizhi introduced that the so-called wireless charging refers to the wireless transmission technology of electric energy realized by non-physical contact.

　　The idea of wireless energy transmission has a long history. As early as more than 100 years ago, Tesla proposed the idea of realizing global wireless power supply through the atmospheric ionosphere.

　　The law of conservation and transformation of energy is universally applicable in nature, and electromagnetic space is no exception, which can be proved by Lenz’s law. The essence of Lenz’s law is that "the magnetic field of induced current always hinders the change of magnetic flux that causes induced current." When the magnetic flux in the coil increases, the direction of the induced current is opposite to that of the magnetic field generated by it, while when the magnetic flux in the coil decreases, the direction of the induced current is the same as that of the magnetic field generated by it. Because electromagnetic induction also follows the law of energy conservation and transformation, people can realize energy transformation and propagation through electromagnetic induction.

　　"Specifically, Wal-Mart’s charging method from a distance is that an electric energy transmitter provides an energy source and emits a certain frequency spectrum in a specific direction range, thus creating a three-dimensional electromagnetic energy space." Yan Huaizhi explained that electronic equipment in the space covered by the RF signal can receive the signal if it is equipped with a signal receiving device with the corresponding frequency spectrum, so as to realize electromagnetic induction with the transmitter, thus "collecting" the electromagnetic energy transmitted by the transmitter through the air from a distance and realizing wireless charging of the receiving electronic device.

　　Wei Zhiqing, an associate professor at the School of Information and Communication Engineering of Beijing University of Posts and Telecommunications, further explained that the working principle of Wal-Mart’s air charging equipment is similar to that of WiFi and Bluetooth, and it consists of a transmitter and multiple receivers. Hundreds of micro antennas are integrated in the transmitter, while the receiver is only the size of a coin and is installed on the equipment that needs charging. The receiver will send a request signal for charging to the transmitter when the power is low. After receiving the request signal, the transmitter will charge the equipment at a frequency of 100Hz per second. In the APP that controls charging, you can specify charging devices and charging strategies (for example, give priority to charging devices with low power), and you can charge up to 32 devices at the same time.

　　Yan Huaizhi said that the distance and charging time that people care about this kind of charging technology can reach mainly depends on two factors, one is the transmitting power of the wireless spectrum of the transmitting device, and the other is the transmitting frequency of the wireless spectrum.

　　According to reports, the laboratory prototype system of Wal-Mart’s air charging device is CotaTile, with the transmitting power of 20 watts, the receiving power of equipment at a distance of 1 meter is about 6 watts, and the receiving power of equipment at a distance of 2 meters is 2 to 3 watts, which can charge equipment at a distance of 10 meters at the farthest.

　　You can also see these wireless charging technologies.

　　In addition to this way of charging from a distance, there are many commonly used wireless charging methods.

　　Yan Huaizhi introduced that the first is electromagnetic induction technology wireless charging, also known as Qi standard wireless charging. At present, this method is mostly used for wireless charging of the latest models of Xiaomi, Huawei and Apple on the market. The user can put the mobile phone on the charging base to charge without charging cable.

　　Wei Zhiqing said that its working principle is that the wireless charging base and the mobile phone are respectively equipped with a transmitting coil and a receiving coil. By using electromagnetic induction, when they are close, the transmitting coil in the charging base is connected with alternating current to generate an alternating magnetic field, and the change of the magnetic field makes the receiving coil generate current, thus transferring energy from the transmitting end to the receiving end, that is, supplying power to the mobile phone from the charging base. The advantage of this method is that the charging efficiency is high, and the charging efficiency of smart phone can reach 80%. The disadvantage is that the charging distance is short, so it is usually necessary to put the phone close to the charging base.

　　Secondly, electromagnetic resonance wireless charging, which uses resonant devices to make the transmitter and receiver reach the same frequency, and the same resonant frequency is a necessary condition for energy transfer, and electromagnetic energy can be exchanged through magnetic resonance. Compared with electromagnetic induction, the advantage of this method is that there is no need to "cling". The charging distance of smart phones can reach 10 cm, but its charging efficiency is slightly lower, usually less than 70%.

　　In addition, there is wireless radio frequency technology, which uses space electric field as energy transmission medium and generates alternating current under the action of alternating electromagnetic field, thus realizing long-distance wireless transmission of electric energy. The advantage of this method is long charging distance, but the disadvantage is strong electromagnetic radiation and low conversion efficiency.

　　Although "wireless" is good, it faces many challenges.

　　"Compared with wired charging, the advantages of wireless charging are very unique, including the convenience of use, the security of transmission, the compactness of the device and the integration of the environment, but there are also many challenges, which are embodied in both technical and non-technical aspects." Yan Huaizhi said that technically, wireless charging involves technical problems such as wireless transmission of power signals, high-frequency conversion, coupling coil design, system collaborative control, electromagnetic shielding and electromagnetic interference. For example, although close-range RFID devices, smart phones, tablets, smart watches, hearing AIDS, etc., to long-distance drones and even spacecraft in space, they can be charged in the air. However, due to the principle of electromagnetic induction, any factors that damage or weaken the propagation of electromagnetic spectrum signals, such as electromagnetic shielding, insufficient power and unstable frequency, will have a fatal impact on it. On the non-technical level, there are problems such as high cost of wireless charging equipment, difficulty in unifying technical standards, and public doubts about electromagnetic radiation.

　　But he believes that these problems will be effectively solved with the further development of technology.

　　Wei Zhiqing added that the biggest problem of wireless charging is the low charging efficiency, which generally only supports 5W charging power, and the slightly faster charging power is only 7.5W. In addition, regarding the public’s concerns about the electromagnetic radiation that may be brought by wireless charging, it is necessary for enterprises and evaluation institutions to conduct rigorous experiments and extensive popularization of science, so as to dispel public concerns. Due to the wide charging range of wireless charging, it will have broad application prospects in the field of Internet of Things in the future.

The replacement of new energy sources with electricity is actually nothing new.

In 1896, Hartford Electric Light Company, born in Hartford, Connecticut, USA, introduced an electric van with replaceable batteries. The buyer only bought the vehicle, but did not include the battery, and then paid the charging and maintenance fee by mileage when using it.

The specific business model is that vehicles are sold to users by GeVeCo (a subsidiary of General Electric), and HELCO is responsible for holding and providing battery packs to consumers. As for users, they buy HELCO’s power exchange service in the form of monthly fee. From 1910 to 1924, HELCO’s power exchange service provided electric trucks with a cruising range of more than 6 million miles.

Nowadays, looking at the power exchange technology of new energy vehicles is more like a "technical revival" that lasted for nearly a hundred years. In the field of commercial vehicles, there are State Grid, Yutong Bus, Beiqi New Energy and other enterprises, while in the field of passenger cars, there are Weilai.

Today, most new energy vehicles have not yet achieved "separation of vehicles and electricity". In 2017, the technology of power exchange was explored, and the first power exchange station was put into operation in 2018. In more than six years, Weilai has built 2,435 power exchange stations nationwide. In these six years, many car companies only chose to follow up on a small number of models.

Even so, Weilai iterated the power station changing technology to the fourth generation. The fourth generation power station, which was officially launched in Guangzhou not long ago, comes standard with six ultra-wide-angle laser radars and four Orin X chips, and supports one-button automatic power exchange and independent power exchange when leaving the vehicle.

Compared with the previous generation, the speed of power exchange is increased by 22%, the fastest time is only 2 minutes and 24 seconds, the number of battery positions is increased to 23, and the maximum number of daily services can reach 480 times.

Moreover, the new power exchange station can also support multi-brand sharing power exchange, including Ledao, which makes many people daydream about the power exchange of more models.

However, in order to make more models have the ability to exchange electricity, it is necessary to build a large enough stage to introduce other car companies and ecological partners.

On November 21, 2023, Changan Automobile announced that it had reached a cooperation with Weilai, and the two sides would jointly research and develop battery-changing vehicles, battery-changing technologies and unified standards. Weilai’s battery-changing camp was expanded for the first time.

However, people’s real re-examination of this alliance may have originated from the dialogue between Li Bin and He Xiaopeng in early May this year. At that time, He Xiaopeng personally visited Li Bin and said that when Weilai replaced more than 5,000 power stations, he would consider joining the power exchange mode.

Soon after, FAW announced that it had reached a strategic cooperation with Weilai for charging and replacing electricity.

Today, the power exchange alliance has seven car partners, including Changan, Geely, Chery, Jianghuai, FAW, GAC and Lotus, as well as energy and power enterprises such as "Three Barrels of Oil", Shell, State Grid, China Southern Power Grid, Wanneng Group, Zhongan Energy, Contemporary Amperex Technology Co., Limited, Zhongchuang Singapore Airlines and Longji Green Energy, with considerable influence.

However, Yang Chao, assistant vice president of Weilai and head of energy product development, told Leifeng. com "New Smart Drive" more than once that Weilai hopes to realize the scale of power exchange infrastructure and share the power exchange mode with the whole China automobile industry, hoping that more brands will join the TV exchange family, so that more users can enjoy the more convenient experience of adding power than refueling.

The efficiency of energy supplement has always been an important factor for consumers to buy new energy vehicles. From the market feedback, the sales growth rate of plug-in hybrid extended-range new energy vehicles has also obviously accelerated.

According to the statistics of the Association, the sales volume of hybrid (including extended range) new energy vehicles in May this year was 308,773, a year-on-year growth rate of 61.1%; The sales volume of pure electric new energy vehicles was 495,825, with a year-on-year growth rate of 27.6%.

In Yang Chao’s view,The reason for the slowdown in the sales of pure electric vehicles is the fuel tank (energy replenishment efficiency).However, there are different technical paths for pure electric vehicles to improve the charging efficiency, such as overcharge +CTB(Cell To Body), battery replacement and so on.

The reason why Weilai set up a power exchange alliance and cooperated with many car manufacturers is actually that it hopes to conduct some benign discussions on the future development direction of pure electric vehicles.

At first, this kind of discussion only existed inside Weilai, focusing on several managers from the State Grid and some Weilai suppliers.However, after more than a year’s efforts, the leaders of all enterprises in the power exchange alliance have reached a consensus and will seriously consider this issue.

Yang Chao believes that this is only the first step, but even so, it has great positive significance:Because through Weilai’s efforts, at least more car companies will realize that what kind of energy supplement scheme pure electric vehicles will adopt in the future requires not only serious thinking, but also pre-research in the next generation of vehicles, and more importantly, how to realize applications more quickly in the current scenario, which will have a chain effect on the whole industry.

However, in his mind, he still has his own ideas about the form of changing power stations in the future.

He told Leifeng. com(WeChat official account: Leifeng. com)"New Smart Drive", just like gas stations, has formed a complete power exchange network in the whole country, which can be operated by the state, enterprises or third parties. The battery also has a set of standard system, and there are several different types of batteries to choose from for different models or mileage requirements. Under such a system, car companies develop models without unnecessary consumption of batteries.

On the contrary, car companies can carry out in-depth exploration in the dimensions of safety, application service, reliability, vehicle intelligence and automatic driving, and hand over the matter of energy replenishment to social resources to solve. Only in the specific practice process, Wei Lai’s team found that the choice of social resources-overcharge scheme can not solve the problem of power grid, nor can it solve the problem of sustainable development, and Wei Lai believes that changing electricity will be the "ultimate scheme" for new energy.

Of course, behind this kind of industry recognition, in fact, different manufacturers compete for battery standards.

In the communication with many car companies, Yang Chao was asked countless times such as "Tesla and BYD have no power exchange business, why others’ sales are very good". For Weilai, even if you tell these friends that your sales are really driven by the power exchange business, it is easy to be questioned.

Therefore, on the one hand, Weilai suggested that these friends conduct user surveys to see how many consumers chose Weilai out of the ability to change electricity.

On the other hand, it launched a new brand-Ledao. Since its birth, Ledao has been highly anticipated, because its sales will influence the promotion of power exchange technology to a certain extent.

Launching vehicle models is an important strategic layout for Weilai to verify and promote its power exchange mode, while the previous experience of fast pile filling shows from another angle that in order to speed up the promotion of a new technology, the most important thing is to formulate industry standards.

According to Yang Chao, Weilai, as an organizational unit or an important participant in China, has participated in the formulation of more than 30 power exchange standards, including the formulation of key standards such as safety, system composition and terminology interpretation.

In addition, Wei Lai also presided over the formulation of some IEC (International Electrotechnical Commission) standards together with State Grid. In IEC, it is rare for Chinese to preside over the formulation of standards.

Yang Chao explained that power exchange technology is a brand-new technology in Europe, and there is no specific standard. In order to ensure that all services meet local standards and regulations, Weilai and relevant European institutions jointly formulated industry standards, which gradually evolved into IEC standards.

Yang Chao said that all standards were originally formulated for safety reasons. Although there is a certain foundation in Europe at present, it is necessary to further strengthen this sense of existence to attract more European enterprises to participate in this process and jointly promote the improvement of standards.

Next, Weilai will further optimize the design of standards, integrate more excellent standards from different enterprises or institutions (such as China Power Research Institute and China Automobile Research Institute) for the market to choose from, and at the same time open its own Konw how to promote the unification and improvement of relevant standards for power exchange technology.

Yang Chao said,The establishment of many standards takes quite a long period. For example, the nature, size, capacity, connector, battery management, adaptability of the three power systems, etc., all need to take time to demonstrate and analyze.Different manufacturers in the alliance have their own design specifications, and if they want to reach an agreement, they need technical compromises.

"This is like a unified charging port for mobile phones. How many years did it take?"

Yang Chao said that it is not that anyone with a loud voice or a strong ability can complete it dramatically in a short time, but what Wei Lai can do is to verify it realistically and coordinate within the alliance until someone is willing (compromise). Just lean together as much as possible. Wei Lai hopes to prove that he can do it first and then help more people.

As we all know, whether it is a charging pile or a power station, the cost is often high when car companies directly participate in the operation. It is easier to "get what you need" with the help of social resources. According to Yang Chao, Weilai has already reached a cooperation with Zhongan Energy in Anhui Province to promote the construction of 1,000 storage, charging and exchange stations based on Anhui and radiating the Yangtze River Delta and the whole country.

The first power exchange station jointly built by Weilai and Zhongan Energy was officially launched in Luoji Service Area of G40 Hushan Expressway in Lu ‘an City, Anhui Province on June 13th, which is also the first Weilai fourth generation power exchange station launched in Anhui Province.

Yang Chao said that Weilai has been exploring the possibility of cooperation with the government. On the one hand, the operation and maintenance cost of changing power stations is high. On the other hand, besides economic benefits, Weilai has wider cooperation space with the local government and can get more policy or other support. Next, it may reach similar cooperation with the Wuhan Municipal Government.

Overseas, the layout of Weilai is also very suitable for the actual situation of the country.

For example, in Denmark, where the power grid construction is not perfect, the power exchange station originally used to serve the automobile business has also played a role in alleviating the pressure on the local power grid. By charging during the wave valley period and discharging during the peak period, many power exchange stations even achieved a profit of more than 4,000 euros per day. To this end, Weilai also specially adjusted the construction strategy of power exchange stations in Denmark, and built more power exchange stations in places where electricity consumption fluctuated to adjust the local electricity consumption situation.

In Hungary, Weilai was originally affected by the epidemic and the transportation cost was high, so it opened a local factory, and then completed some assembly tests of vehicles in China, and left the rest of the work to the Hungarian factory, which greatly reduced the cost.

Hungary was originally short of natural resources, so the government is very interested in the energy storage project derived from Weilai Power Exchange Station, hoping to further cooperate with Weilai, and Weilai also intends to promote the power exchange station integrating electricity exchange and energy storage to the whole of Europe through the pilot project with Hungary.

According to Yang Chao, Weilai has projects in Denmark, the Netherlands and Hungary, and has also cooperated with some universities in Germany.

As the batteries of the first batch of electric vehicles gradually reach the limit of service life, how to recycle and reuse the batteries reasonably has become the focus of the industry.

As an advocate of power exchange technology, Weilai will also face this problem directly, and the power exchange station, as a natural "battery maintenance center", can play a positive role in prolonging the service life of batteries through more reasonable and optimized management of battery storage environment and charging power.

According to Yang Chao, Weilai is currently promoting the life-cycle management technology of batteries to extend the service life of batteries as much as possible, and at the same time, it has also invested in research and development of technologies related to automatic disassembly and refined recycling of batteries to maximize the value of batteries. With the opening of the power exchange network, there are many stories told by Wei Lai to exchange electricity.

Original Dr. Wang Cardiovascular Doctor Wang Cardiovascular Doctor Wang

Many friends on the Internet consulted Dr. Wang and said that they had heart surgery. What should they pay attention to in the future?

Dr. Wang: There are many heart operations. Please specify what kind of heart operations?

Cardiovascular medicine has developed rapidly, especially many heart diseases can only wait for death many years ago, but now they have developed to the point where they can change their hearts.

Different heart diseases will choose different heart operations. What is the difference between these common heart operations?

We still compare the heart to a high-tech house first, with waterways, circuits, frames, doors and windows, etc., but the house sometimes has to be repaired, so there are various heart operations:

1, the heart stent:

Minimally invasive surgery in internal medicine, the patient is completely awake and does not need surgery;

It enters from blood vessels and is used for coronary heart disease, that is, cardiovascular stenosis or blockage. Stents are used to support the narrow place, so it is called heart stent. Cardiac stent is a good surgical method for angina pectoris caused by sudden occlusion of blood vessels in acute myocardial infarction and uncontrollable drugs.

Coronary heart disease, whether stent or not, needs to adhere to a healthy life and take medicine!

For example, the water pipe in our house is blocked, so we open it first, and then put a mesh shelf in the blocked pipe to prevent it from being blocked again.

2, heart bypass:

In surgery, patients need general anesthesia and even cardiac arrest;

Take a few blood vessels from other parts of the body and sew them on the heart, which is also used for coronary heart disease, that is, if the blood vessels are narrow or blocked, they are not suitable for stents, and they can be bridged to establish a new channel for blood supply. Most heart bypass operations also require thoracotomy.

After bypass surgery, you also need to take drugs for coronary heart disease for a long time and live a healthy life!

For example, the water pipe in our house is blocked, but we can’t open it. What should we do? Build a new pipe to pass water.

3. Pacemaker:

Medical surgery, patients with local anesthesia, need to open a small incision;

It’s just that the heart beats too slowly, and if there is no way to control it, it will faint and die, but the blood supply and ejection function of the heart are ok. Simply put, the heart’s own battery is not working. Put an artificial battery to power the heart and make it beat normally. There is also a pacemaker for the treatment of heart failure, which says heart transplantation, but after all, it costs a lot and there are few donors, but people with advanced heart failure also need treatment. There is a three-chamber pacemaker for the treatment of heart failure, which belongs to internal medicine treatment.

After ordinary pacemaker surgery, it is necessary to check regularly every year to see if the pacemaker works normally, monitor whether the battery is charged, and do not need to take medicine after the heart rate is slow; Three-gun pacemaker, simply understood, is to make the heart beat more normally, and drugs for heart failure need to be taken regularly.

For example, our house was cut off and we bought a generator, but this generator can only be used for 8 years, so we have to replace it.

4, cardiac radiofrequency surgery:

Keywords internal surgery, minimally invasive, vascular operation;

It says that the heart rate is too slow. You can use a pacemaker to treat it. Install a battery. But the heartbeat is chaotic, that is, the circuit in the heart is broken, and the heart is always jumping or beating too fast, so try to burn this circuit short with electricity, which is the radiofrequency ablation of the heart. Burn the extra road, the heart can only beat according to the normal route and return to normal.

Radio frequency surgery, some heart diseases with fast heartbeat can be cured, no need to continue taking medicine!

It’s like the circuit in our house is out of order. Let’s rearrange it.

5, cardiac occlusion:

It belongs to minimally invasive surgery in internal medicine. One is that the left atrial appendage is a method to treat atrial fibrillation with thrombosis. Atrial fibrillation is prone to thrombosis, and cerebral infarction will occur when the thrombus falls. We try to plug the place where the thrombus forms, so that the thrombus will not fall and the cerebral infarction will not occur.

After operation, it is necessary to monitor whether the heart rhythm recurs and take anticoagulants for a period of time.

There is also a congenital heart disease, which is more common in young children. After birth, it is found that there is a hole in the wall of the heart, and some people try to mend it.

For example, there is a leak in the house, and we try to plug it with something.

6, heart transplantation, heart change:

It should be the biggest operation among all heart operations. You can understand that it is very high-tech to cut off the patient’s heart and transplant another heart to the patient. It also needs a heart provider. It is a very big operation, and the cost is relatively expensive. There are also a certain number of heart providers. People who generally need a heart change are mostly in the late stage of heart failure, and the drugs are basically ineffective, but other organs are not bad and young, so they will consider a heart change.

This is easy to understand, the house is not working, change the house!

These are several common cardiac operations. The development of various cardiac operations has improved the symptoms of many patients and extended the life span of many patients, but again, many diseases can be prevented.

The best treatment is not surgery, but prevention!

GAC Trumpchi E8 is sure that everyone is not unfamiliar with it. Since its listing, this car has quickly become an absolute hit in the 200,000-class new energy MPV market. To some extent, it has formed a very large competitive pressure on the Odyssey under the same GAC. On various platforms, the E8 is often used for direct comparison with the Odyssey.

Boss, the Trumpchi E8 new energy information you want.

Not long ago, Trumpchi E8 launched a new version, called the glory version. This glory version is completely different from BYD’s glory version. Compared with the original plug-in version E8, the biggest change of the E8 glory version is that it replaces the entire power system. The original is a 2.0LPHEV plug-in system, and the glory version has become a 2.0L oil mix system. The price has also changed compared to the plug-in version. The new car is now priced at 16.68-17 9,800 yuan.

So for this new version of Trumpchi E8, the price has changed, and the power system has also changed. How should I choose between its two versions?

As mentioned earlier, the biggest change in the Trumpchi E8 Honor Edition is its power system. In fact, to be fair, this oil mixing system is actually quite interesting. First of all, the engine is the same as the plug-in hybrid version, or the hot topic efficiency 2.0L self-priming hybrid special engine, with a maximum horsepower of 140 horsepower. Let’s not say that its engine power is not good, let’s read it down first.

This car is equipped with a front 182 horsepower single motor, and the 140 horsepower of the engine adds up to a maximum output of 322 horsepower, which is not weak at all. You may think it is strange when you see this. Don’t oil-mixed cars use the engine as the main force, and the motor is generally very small in horsepower? Why is the motor of the E8 Honor Edition so powerful?

In fact, what’s more interesting is that if you just look at the whole power system, you will find that whether it is engine horsepower or motor horsepower, it is almost no different from the plug-in hybrid version. To put it bluntly, the overall structure of the oil-mixed system on the Honor version is similar to that of the plug-in hybrid version, with only two changes: first, because this is an oil-mixed system, its battery is much smaller than the plug-in hybrid version (which is also the source of its cost reduction and car price reduction), and secondly, because it is an oil-mixed and the battery is small, it cannot be charged directly with a charging pile like a plug-in hybrid. The logic of the entire electronic control system is also a typical oil-mixed logic. In other words, its high-power motor and small battery necessarily mean that the car does not have much pure battery life. It is a very typical oil-mixed car working mode.

However, according to the official data of GAC Trumpchi, the WLTC comprehensive fuel consumption of this car can also achieve 5.58L, and the comprehensive cruising range is not mentioned, but the fuel tank of this car is 60L, and as a fuel hybrid car, the actual fuel consumption is very close to the official standard data (the fuel hybrid car does not have any feed fuel consumption), so this car can actually calculate the actual cruising range of at least 700 kilometers.

The Trumpchi E8 Honor series is divided into two versions, namely the 166,800 Zhizai version and the 179,800 Honor version. These two versions are completely consistent in terms of body size, wheelbase, etc. Equipped with the oil mixing system introduced above, the front McPherson rear torque beam suspension has not changed, but the appearance can still distinguish these two versions, low with front and rear 17-inch wheels, high with front and rear 18-inch wheels.

In addition to the above, there is naturally no difference in the basic configuration such as basic airbags. The price difference between the two versions 13,000 is actually mainly reflected in the intelligent driving system. Highly equipped with a full-featured L2 auxiliary driving system, all mainstream L2-level functions are available, but limited by positioning, this L2-level system does not have any NOA autonomous driving function.City NOAOf course, there is no high-speed NOA. And the L2 system has no low-end configuration at all, so it can be said that the existence of the L2 system is the most obvious configuration difference between the two versions.

Of course, they also have some other configuration differences, such as high with electric tailgate and low with no, high with LED daytime running lights, low with no daytime running lights, the structure of the E8 car does not have a panoramic sunroof, but high with front and rear segmented multiple sunroof, low with only one sunroof in the front row. Of course, high with front sound insulation glass low with no, high with induction wipers low with full manual wipers, high with front with 50W mobile phone wireless charging board low with no at all, high with front seats with heating and ventilation, low with no, high with front co-pilot electric seat, low with co-pilot please adjust manually. High with second row with zero gravity seat, low with no.

Boss, the Trumpchi E8 new energy information you want.

To put it simply, the two versions are actually very different in configuration. Obviously, Trumpchi’s positioning for these two versions is very clear. If you are buying a car for home use, it is natural that you should choose a high-end model. After all, the low-end model lacks too many configurations, and these missing configurations are quite important for home use.

But can you say that the low-end car has no purchase value? No, no, the low-end car is actually for business reception purposes. To put it bluntly, it is bought by the rental car company as a reception car, or the company buys it as a company reception car. People with this purpose are very sensitive to price. On the contrary, configurations such as L2 system, zero gravity seats, and whether there is double-layer sound insulation glass in the front row are not important to the needs of business. Anyway, this kind of use is basically driven by a full-time driver.

In fact, we believe that there is still room for adjustment in the price of the low-end version, or Trumpchi actually has the relevant price of government and enterprise vehicles for the low-end version of this car. After all, its low-end version seems to be tailor-made for government and enterprise vehicles.

Seeing this, you will naturally recall the Odyssey, which is an old rival of the E8 car series. In fact, to put it bluntly, these two cars have a history. But since the E8 is now directly competing against the Odyssey, let’s briefly talk about how it and the Odyssey should be selected.

In fact, it is also very simple. The appearance difference between the E8 Honor Edition and the Odyssey is very obvious. If it is a more composed style, then the Odyssey is the first choice. If you prefer a young maverick, then the E8’s headlights can also satisfy you. The appearance alone is actually enough for consumers to make a choice.

As for the low-end version of the E8 Honor Edition, as I just said, this version is for government and enterprise use, and it does not need to compete with other competitors.

One Shen Teng and the other Jason Wu have become historic actors in Chinese film history, but Jason Wu’s box office appeal is even more abnormal.

It’s not difficult for The Battle at Lake Changjin to break 4 billion, and many platforms predict that it will become the next 5 billion box office movie.

Behind Jason Wu, there are Changjin Lake 2, Wandering Earth 2 and War Wolf 3. Once these three films are released, as long as the quality is equal to or slightly better than the previous ones, the box office will be high.

At that time, Jason Wu was definitely the "One Super" in the six Mesozoic Era, while others were "How Strong". Although he is now the "One Super", what will happen to Jason Wu’s status and influence after The Battle at Lake Changjin?

The flattery of other stars, the change of other capital and the enthusiasm of other stars can show Jason Wu’s status.

He created a military action film, which revived China’s sci-fi film Dirty Land and made the Chinese values in Chinese-language films recognized.

Let the main theme return to the C position of mainstream movies, turn the rational trend of bad movies into word of mouth, and let middle-aged and elderly people enter the cinema.

Before that, Zhang Ziyi was an international chapter, and there were few opportunities for Jason Wu to be on the same stage with her, because their coffee tables were very different.

However, after Jason Wu reached the top of the box office champion in China’s film history and became Mr. Billion Box Office with two films, Wolf Warriors 2 and The Wandering Earth, Jason Wu completely turned over and became a big shot.

During the publicity of "My Father and I", Zhang Ziyi was a "Jingge", and he was very kind. Maybe he didn’t even look at Jason Wu before.

At that time, Jason Wu played a brilliant supporting role in "kill the wolf", and it was just a short time before Donnie Yen and Jason Wu could be compared.

Therefore, the discussion about the street fighting between him and Jason Wu in kill the wolf is not very hot, but after 2017, the street fighting has an unprecedented flow.

The media kept asking questions, and Donnie Yen kept responding, and even used it as an explosive stalk in the Tucao Conference.

At the beginning of the 20th century, there were also TV dramas with high popularity, such as Fengyun, come drink with me and The Legend of Wu Mei Niang.

It was only later that he "made" his own superstar road. After Jason Wu’s fire, he was all kinds of enthusiasm, and the manuscript said that he starred in War Wolf 3.

All three of them used to be bigger than Jason Wu, but now they have become the beneficiaries of Beijing.

After Hero, commercial films appeared on the historical stage, and various blockbusters emerged one after another. Golden Flower in the City and Banquet were the mainstream of that period.

After Xú Zhēng’s "Embarrassment of Thailand" became the first domestic comedy in China to break 1 billion, the comedy became a big hit, dominating the domestic box office for ten years, and the heat is still there.

After "Wolf Warriors" became a dark horse, China added a new genre of military action movies, and the "country" in the world became a box office panacea.

After the release of The Wandering Earth, the box office kept rising due to its good reputation, and domestic sci-fi films gave the audience hope, although "Shanghai Fortress" almost failed the "Hundred-day Innovation of Sci-fi Films".

Fortunately, The Wandering Earth has brought many special effects talents to China films, and "home" in the world has also become a box office medicine.

Those who commit crimes against China will be punished far away; Home is our root. Even if the earth is in danger, we will not run away, but wander with it.

This kind of values that every mainlander has carved in his bones since childhood is not comparable to Tsui Hark’s "Taking the Tiger Mountain Outward" and Lin Chaoxian’s "operation mekong" and Operation Red Sea’s.

Bad movies, dogma and rigidity are all synonymous with it. As soon as the audience sees it, they want to poke their eyes and ask people around them for a pair of eyes that have never seen the film at a high price.

Thematic blockbusters such as "The Founding of the People’s Republic of China" and "beginning of the great revival" are rare, and the reputation at that time was not very ideal, and the popularity was also supported by the luxury version of the star lineup.

Even if there are no big names and stars, they can have a high popularity, such as "1921" and The Pioneer.

Later, My People，My Country and My People My Homeland are rare scenes to reproduce word-of-mouth and box office in Qi Fei.

This is a good thing that Huang Jianxin couldn’t even think about before, and it is also a booster for the country to try to reverse people’s public opinion.

The appearance of "Wolf Warriors 2" broke the rule that bad movies have high box office, and the hammer’s "to the sky kingdom" could not find the north, which also made "to the sky kingdom" a stepping stone for good money to drive out bad money.

This stone "Beijing" has caused a thousand waves of China movies, and word of mouth has become the most important thing to measure the quality of movies, but the number of stars is no longer important.

Jason Wu-based large-scale production of main theme blockbusters has made many people who have rarely set foot in cinemas in the 1960s and 1970s become frequent visitors to cinemas again, increasing the audience of movies.

He, like Jackie Chan, is a favorite actor of CCTV. Last Spring Festival Gala, he definitely won the C position. At the same time, Jason Wu and Jackie Chan will encounter new troubles, and they may never play the villain, so they all have to be positive images.

This may be a pity for the fans, because they will never see kill the wolf, Wei Cheng, Handsome, and True Men again.

　　From January 1 next year, the "late payment fee" for bank credit cards will be cancelled, and the overdraft interest rate can be up to 30%, and the interest-free repayment period may exceed 60 days. This is undoubtedly full of benefits for people who often use credit cards.

　　In April this year, the Notice on Matters Related to Credit Card Business issued by the Central Bank (hereinafter referred to as the "new regulations") will be implemented the day after tomorrow. Recently, the Beijing Morning Post reporter investigated the credit cards of many banks and found that most bank credit card centers have posted relevant implementation announcements, while some banks have begun to implement some new policies.

　　The new regulations have increased the market pricing attributes of credit cards and made the rights and interests of credit cards more diversified. In the future, when consumers use credit cards, they can shop around and choose the card that suits their card habits.

　　1 overdraft interest rate changed to 0.035% to 0.05%.

　　"The bank has changed the overdraft interest rate to the range of 0.035% to 0.05%, and it will be implemented from January 1 next year." The staff of the Credit Card Center of Guangfa Bank told the Beijing Morning Post that from January 1 next year, if the cardholder touches the overdraft interest rate, it will be implemented in accordance with the new regulations. Cardholders with different comprehensive credit background will also enjoy differentiated overdraft interest rates. The reporter’s investigation found that at present, banks generally adjust overdraft interest rates to the range of 0.035% to 0.05%.

　　In fact, if the cardholder fails to repay on time after using the credit card, he needs to pay the interest according to the overdraft interest rate stipulated by various banks. Banks generally stipulate that the number of days to pay interest is from the date of cardholder’s consumption to the date of return.

　　According to the new regulations of the central bank, the upper limit of credit card overdraft interest rate is 0.05% and the lower limit is 0.7 times of the upper limit. The method of calculating and settling interest on credit card overdraft, whether to calculate and pay interest on credit card overpayment and its interest rate standard shall be determined by the bank.

　　Before the implementation of the new regulations, there was no floating space for overdraft interest rates, and the interest rates implemented by banks were generally 0.05%. For the overpayment, at present, all banks basically do not pay interest, but in the future, for the sake of competition, some banks may break this "convention".

　　The central bank said that at present, the risk control ability and pricing ability of credit cards of various card issuers are uneven, and guidance on the upper and lower limits of interest rates is conducive to preventing individual card issuers from blindly reducing prices and fighting price wars. "Under the current situation that the information disclosure mechanism needs to be strengthened, setting an overdraft interest rate ceiling is conducive to preventing individual card issuers from unreasonably charging excessive interest and protecting the legitimate rights and interests of cardholders."

　　The interest-free repayment period is determined by the card issuer.

　　According to the new regulations of the central bank, the conditions and standards for cardholders to enjoy the interest-free repayment period and the minimum repayment amount for overdraft consumption are determined by the card issuer. Previously, the central bank stipulated that the maximum interest-free repayment period of credit cards was 60 days, and the minimum repayment amount in the first month should not be less than 10% of the overdraft balance of the month.

　　Dong Zheng, a senior credit card expert, said that this means that there may be 90-day interest-free products for bank credit cards in the future. When cardholders choose credit cards, they may compare them in this respect. For small banks, such products can increase their competitiveness.

　　In the reporter’s investigation, it was found that most banks still maintain an interest-free period of up to 60 days. However, for the minimum repayment amount, some banks have indicated that it will be implemented according to 5% or 10% of the overdraft balance of the month.

　　The central bank said that the previous regulations made card issuers lack flexibility and space for differentiated services to customers at different levels, which was not conducive to independent innovation and service improvement by card issuers. The new regulation cancels the above restrictions, aiming at giving card issuers more independent decision-making space. Card issuers can flexibly combine the interest-free repayment period and the minimum repayment amount according to their own business strategies and the risk level of cardholders, providing cardholders with diversified choices and forming a market structure with dislocation competition and complementary advantages.

　　3. Exceeding the credit line shall not be charged with exceeding the limit fee.

　　If when you use a credit card, in a billing cycle, the accumulated amount of credit line exceeds the credit line actually approved by the card on the billing date, you have to pay a certain percentage of the excess fee in the past. However, according to the new regulations of the central bank, if the card issuer provides card services that exceed the credit line, it shall not charge the over-limit fee.

　　In the reporter’s investigation, it was found that many bank credit cards have cancelled the over-limit fee. CITIC Bank said that the bank will cancel the "credit card over-limit fee" service item from June 1, 2013, and will continue to adopt the free strategy. In September this year, China Merchants and other banks cancelled the credit card over-limit fee. Banks such as Shanghai Pudong Development Bank, Shanghai Communications Bank and Ping An Bank said that they would cancel this charging item from New Year’s Day next year.

　　As for the prohibition of charging over-limit fees, the central bank said that at present, card issuers have been able to automatically control transactions exceeding the credit line through technical means, and the purpose of covering costs and risks can also be achieved by charging interest on over-limit overdrafts. Therefore, it is forbidden for card issuers to charge cardholders over-limit fees to standardize the service charges of card issuers.

　　4 Cancel the agreement on whether to collect liquidated damages.

　　According to the new regulations of the central bank, the late payment fee for credit cards will be cancelled. For the cardholder’s overdue repayment, the card issuer should agree with the cardholder whether to collect liquidated damages through agreement, as well as the relevant collection methods and standards. In addition, the card issuer shall not charge interest on the service fees such as liquidated damages, annual fees, cash withdrawal fees and currency exchange fees charged to cardholders. This new regulation is regarded by the industry as the most influential one in the Notice.

　　The reporter’s investigation found that at present, most banks have cancelled the late payment fee and increased the amount of liquidated damages. At present, the penalty imposed by most banks is "5% of the unpaid minimum repayment amount", which is consistent with the previous late payment policy.

　　Dong Zheng said that changing "late payment fee" to "liquidated damages" is not just a change in name. Late payment fees are more "administrative", while "liquidated damages" are more negotiable. And compared with the interest charged for the overdue fine, the service fees such as liquidated damages will not be charged with interest.

　　Take ICBC as an example. In its announcement, it is stated that the liquidated damages are "charged at 5% of the unpaid minimum amount, with a maximum of 500 yuan RMB or HK$ 500 or MOP 500 or US$ 100 or Euro100 per period (the remaining foreign currency accounts are charged at a maximum of US$ 100 equivalent in foreign currency) or as agreed".

　　In addition, the reporter found that banks have different regulations on the minimum amount of liquidated damages. Among them, Guangfa, CITIC and other banks charge 20 yuan the lowest penalty, while banks such as transportation and investment promotion charge 10 yuan the lowest penalty.

　　5 The cash withdrawal amount is raised to a maximum of 10,000 yuan per day.

　　From the day after tomorrow, the amount of cash withdrawal by credit card will be raised to a maximum of 10 thousand yuan per day. According to the new regulations, cardholders can obtain the funds within the cash limit of credit cards in cash through self-service machines such as counters and automatic teller machines (ATMs), and the accumulated amount of each card should not exceed RMB 10,000 per day.

　　In fact, the current daily accumulated RMB per card is only 2000 yuan. The central bank said that for other cash advance business limits, the card issuer will independently agree with the cardholder through an agreement according to the business strategy, the cardholder’s risk level and the limit setting requirements.

　　Not only that, the new regulations also stipulate that card issuers can decide whether to provide cash recharge service and agree with cardholders on the daily limit of each card, but they are not allowed to transfer the funds within the cash limit of cardholders’ credit cards to other credit cards or non-cardholders’ bank settlement accounts or payment accounts.

　　In the reporter’s investigation, it is found that most banks still retain the credit card transfer function, but some banks have suspended the credit card transfer function.

　　■ correlation

　　Double-label credit cards will gradually withdraw from the market next year.

　　In addition to the changes brought by the new regulations to credit card holders, the withdrawal of dual-label cards will also affect the use of cardholders to some extent. In November, the central bank held a meeting on the issuance management of foreign currency single-label cards and double-label cards, and decided to suspend the issuance of double-label cards in the future, and the expired double-label cards will also become single-label cards.

　　Dual-label cards that have been circulating in China for 14 years, as well as "China UnionPay+Overseas Card Organization", are regarded as "deformed children" by the industry, and will gradually withdraw from the historical stage of China in the future.

　　People familiar with the matter said that the central bank reiterated the withdrawal of dual-label cards in this meeting, and stressed that banks should not release new products of dual-label cards, but the dual-label cards currently in use can still be used, but the expired dual-label cards can only become single-label cards operated by only one card organization.

　　"It is not overnight for the central bank to stop the double-label card." Dong Zheng said that the central bank had repeatedly asked the dual-label card to withdraw from the market. "The central bank reiterated that it is likely to pave the way for overseas card organizations to enter the China market next year."

　　Many cardholders feel a little troublesome when they spend money abroad. However, Dong Zheng said that double-label credit cards are generally magnetic stripe cards, which are not as safe as single-label cards of chips.

　　In addition, some insiders suggest that people who often go abroad can carry three single-label cards, one UnionPay, one Visa and one MasterCard, of which one is "full currency".
