Is it reasonable to raise the small secret exemption limit of UnionPay card to 1000 yuan by default?

  Beijing, June 1 ST (Reporter Qiu Yu) Is there a word "flash payment" written on your bank card? If there is, you should pay attention. Starting from today, the single limit of small amount of confidentiality and visa exemption for UnionPay cards will be raised from 300 yuan to 1000 yuan.

  The reporter’s investigation found that many people don’t know that the bank "defaults" to open the function of small amount of confidentiality and visa exemption. What is a small amount of confidentiality and visa exemption? Is it reasonable for banks to open by default? Can I get compensation if my brush is stolen?

  What is a small amount of confidentiality and visa exemption?

  Simply put, this is a kind of "pay with one stroke" payment experience. Within a certain amount, you can complete the payment without entering a password and signature.

  Unionpay’s small confidential exemption visa was launched by China UnionPay in 2015, which is convenient and efficient.

  Which bank cards have this function? According to the announcement issued by UnionPay, cardholders need to use UnionPay chip cards or mobile payment devices with "flash payment" function. In other words, the magnetic stripe card cannot enable this function.

  The single limit was raised from 300 yuan to 1000 yuan.

  According to the announcement issued by UnionPay, starting from June 1, 2018, China UnionPay will jointly optimize the function of "small-amount confidential exemption and visa exemption" with member institutions. At that time, the single limit of small-amount confidential exemption and visa exemption for UnionPay chip debit cards and credit cards will be raised from 300 yuan to 1000 yuan.

  The reporter consulted a number of banks on May 31 and found that many banks have raised their quotas.

  According to the customer service staff of CITIC Bank in Beijing, the single consumption amount of small-sum confidential exemption and visa-free is no more than that of 1000 yuan, and the cumulative consumption amount of a single card per day is no more than 3,000 yuan.

  Bank of China, China Merchants Bank, etc. have issued announcements in official website to increase the quota, announcing that the single quota for small-sum confidential exemption will be raised from 300 yuan to 1000 yuan.

  Generally, the function is "default".

  You can pay by credit card without password, which makes many people worry about the security of bank cards. Then, when opening this function, did the bank get the consent of the cardholder?

  According to the information of UnionPay official website, small-sum confidential exemption and visa-free is a mature payment method in the world, and it is also the basic function of the default opening of bank cards, which makes cardholders pay more conveniently and quickly.

  According to previous media reports, Cardo, a newly-developed UnionPay chip in most banks, has opened a small amount of confidential and visa-free payment service by default, but the opening of this service does not require the prior consent of the cardholder.

  To this end, the reporter consulted the customer service staff of China Bank, Industrial and Commercial Bank of China and other banks in Beijing, and was told that this function is enabled by default, but cardholders can apply to close it.

  According to the information disclosed by UnionPay official website, if the cardholder wants to turn off this function, he can contact the issuing bank to turn it off. At present, most issuing banks have supported the turn-off function.

  Is the "default" opening reasonable?

  "If the bank sets the small amount of confidential and visa-free payment function as the default, there is a problem in the procedure." Li Jiquan, a senior partner and lawyer of Beijing Junbang Law Firm, said, "Users have the right to know and choose. Banks should fully and effectively inform users of relevant contents and risks when opening the above functions, and let them sign for confirmation. "

  Li Jiquan pointed out that the decision of the bank to raise the payment limit needs to be made known to the cardholder himself. In this way, the cardholder can realize the possible risks when the bank card is held by others.

  Xiong Dingzhong, secretary-general of Tsinghua University Internet Law and Policy Research Center, said in an interview with Zhongxin.com that opening the secret-free function will indeed bring convenience to users, but it will also increase users’ risks. This kind of service should be specifically informed separately in the format contract between the user and the bank, just as the bank can’t open the U shield payment function by default.

  If this function has been enabled by default, Liu Junhai, director of the Institute of Commercial Law of Renmin University of China, believes that banks can tell users about the small-sum confidential and visa-free payment function by SMS, and if users disagree, they should be able to cancel it at any time.

  If the brush is stolen, you can get compensation

  Several users who hold bank cards with flash payment function said that they did not know that the bank card had been opened with the function of small secret-free and visa-free payment. While pursuing convenience, how to ensure the safety of using the card has become the most concerned issue for consumers.

  Considering the security of bank cards, in order to enhance the cardholder’s confidence in using the card, UnionPay pointed out in the announcement that for the loss caused by card theft and loss, if the compensation conditions are met, the cardholder can get compensation within a certain amount within 72 hours before reporting the loss.

  According to the information of UnionPay official website, if a small amount of confidential and visa-free transactions are stolen within 72 hours before the loss is reported, you should call the customer service of the issuing bank as soon as possible after the loss is reported, and apply for compensation according to the process of the issuing bank. The application materials to be provided by the cardholder generally include the cardholder’s identity certificate, the UnionPay card transaction denial statement, etc. After the application materials are approved, the compensation funds will generally be returned to the account designated by the cardholder within 10 working days. The payment time limit of different issuing banks is different.

  In this regard, Li Jiquan believes that if the customer is in a known state for opening a small amount of confidential and visa-free payment function, then the compensation within 72 hours is a supplement to the contract between the two parties; If the customer doesn’t know about this function, it can only be said that it is a remedial measure for the bank’s own behavior.

  Liu Junhai said that "compensation can be obtained within a certain amount" is rather vague, and suggested that it should be changed to "full compensation", which is the key to enhance the confidence of cardholders and can relieve users’ worries about the safety of using cards. (End)

  Core reading

  The "enterprise problem clearing mechanism" initiated by Nanjing Customs strives to accurately focus on the development problems of industries and enterprises. By comprehensively using various communication channels of "internet plus Customs" and "online+offline", it explores and constructs a new communication mode between enterprises (citizens), realizing "zero distance" in communication and interaction between enterprises and enterprises, "zero obstacles" in solving problems, and striving for "zero inventory" in enterprise problems. Realize the "full chain" and "closed loop" management of enterprise demands, and ensure that "everything is echoed and everything is implemented".

  □ Our reporter Cai Yanhong

  How to get through the "last mile" of service enterprises, change the phenomenon that service enterprises are anticlimactic and their demands are delayed for a long time? Since the beginning of this year, Nanjing Customs has taken practical measures to optimize the business environment, focused on serving the people and solving problems, explored and innovated and established a set of "enterprise problem clearing mechanism", actively responded to the demands of enterprises, promptly solved problems and served the development of enterprises.

  Recently, the reporter learned in an interview with Nanjing Customs that from January to August this year, Nanjing Customs accepted 5,462 difficult problems of enterprises through various channels, and solved 5,358 problems, with a problem solving rate of 98%.

  Communication and interaction between enterprises and enterprises to achieve zero distance

  “‘ Enterprise problem clearing mechanism ’ The proposal stems from the feelings of Wu Haiping’s grassroots research. " Wu Wei, deputy director of Nanjing Customs Office, told reporters.

  Wu Haiping, Commissioner of Nanjing Customs, found that some enterprises raised a series of questions at different times, on different occasions or in different regions, but after listening carefully, many of them were "familiar". "Some problems have appeared repeatedly. On the one hand, they have not solved the problem in a real, deep and thorough way; On the other hand, some thorny problems are difficult to solve for a while, and it takes great efforts to make a long-term contribution. " Wu Haiping said.

  In this regard, on January 3rd this year, Nanjing Customs officially launched the "enterprise problem clearing mechanism", striving to accurately focus on the development problems of industries and enterprises. By comprehensively using various communication channels of "internet plus Customs" and "online+offline", we explored and constructed a new communication mode between enterprises (citizens), realizing "zero distance" in communication and interaction between enterprises, "zero obstacles" in solving problems, and striving to "zero inventory" in enterprise problems. Realize the "full chain" and "closed loop" management of enterprise demands, and ensure that "everything is echoed and everything is implemented".

  "Within the customs, through the comprehensive coordination, functional management, legal, business experts joint guidance of inter-departmental ‘ Consultation ’ Establish and improve the problem-solving mechanism, make precise efforts, and solve problems for enterprises. " Wu Wei further introduced that, at the same time, we should pay attention to the post-clearing evaluation of problems, guide enterprises and clients to conduct online evaluation of problems that have been solved or responded to, and the customs should pay a timely post-clearing visit, and regularly "look back" on the handling of difficult problems to ensure that the problems are really "cleared".

  "For summary and combing, it has been ‘ Clear ’ Typical problems, by analyzing cases from point to area, sharing experiences, popularizing solutions, warning risks, standardizing and unifying law enforcement, and promoting problems ‘ Batch clearing ’ ‘ Overall clearing ’ Strive to solve a difficult problem, solve a class of problems, serve an enterprise and facilitate an industry. " Zhang Yaping, deputy director of Nanjing Customs and director of Jinling Customs, added, we should strengthen functional guidance on common disputes, eliminate law enforcement disputes, give early hints on major risks and hidden dangers, draw a relatively unified law enforcement scale for the discretionary power with excessive flexibility, and do a good job in supporting and optimizing system norms.

  In order to establish a scientific, accurate, efficient and long-term working mechanism of enterprise problem collection, handling and feedback, on August 20th, "Nanjing Customs Enterprise Problem Clearing Management System" was officially launched. According to Shi Jianping, director of the Open Government Affairs Office of Nanjing Customs Office, through this system, enterprises can reflect problems at any time through computers and mobile phones without being limited by time and place, and realize "zero distance" in communication between enterprises and enterprises.

  Three ways to promote enterprise problem clearing

  China Communications Tianhe Machinery Equipment Manufacturing Co., Ltd. is a Sino-Japanese joint venture shield machine production and service enterprise. "Due to the change of the Malaysian government, the two shield machine contracts signed by the company and Malaysia could not be performed normally, resulting in the failure to implement and write off the corresponding import processing trade manual normally, which brought great tax and fee pressure to enterprises, thanks to the guidance and settlement of the customs." Now, talking to reporters about the past, Zhou Jun, the company’s deputy general manager, has a relaxed face.

  At that time, in response to the problems reflected by enterprises, Nanjing Customs, under Changshu Customs, set up a problem clearing working group headed by Commissioner Chen Xindong at the first time, and led relevant departments to go to China Communications Day and the company for on-site work. "Soon, we received the solution provided by the customs. According to the calculation, the company can reduce the cost by more than 10 million yuan." Ren Linyi, deputy manager of the company’s material procurement center, said gratefully.

  When interviewed by Changshu Customs, the reporter saw a "Contact Card for Enterprises" with a two-dimensional code, which was printed with the business functions of various departments of Changshu Customs and the contact information of the main person in charge. Enterprises can directly log in to Changshu Customs Enterprise "Problem Clearing" WeChat official account to make comments and reflect problems to the Customs. The customs has a special person responsible for maintenance, collecting problems and responding to feedback in time.

  "Changshu Customs has put forward various types for enterprises ‘ Question ’ , according to ‘ Clear ’ The idea is divided into three solutions. " Chen Xindong explained to reporters: for the problems within the scope of customs functions, answer and solve them on the spot, that is, "clearing them on the spot"; For the problems that are reasonable in appeal but need to be solved by the higher customs, we should actively reflect them, do a good job of tracking and coordinating, and strive for the "early clearing" of the problems; For the demands put forward by enterprises that do not conform to the provisions of national laws and regulations, we will solve doubts on the spot, and arrange relevant departments to jointly carry out policy research with enterprises, so as to maximize the benefits of enterprises through other means, get the understanding and support of enterprises, and realize the problem of "clearing the mind".

  Those who can answer at the scene will never spend the night

  When Nanjing Customs is subordinate to Wujiang Customs, the reporter saw a thank-you letter from Changxu Electronics (Suzhou) Co., Ltd. (hereinafter referred to as Changxu Electronics). Changxu Electronics is a wholly foreign-owned enterprise controlled by a French company. Its products are mainly used in medical devices, consumer electronics and industrial control.

  Speaking of this thank-you letter, Ma Honglan, director of Wujiang Customs, still remembers it vividly. At 5 o’clock in the afternoon on August 19 this year, it was time to get off work. After a busy day’s work, Ma Honglan just breathed a sigh of relief when a middle-aged lady stormed in.

  "Commissioner Ma Guan, I am Zhang Xinhua, general manager of Wujiang Branch of Suzhou Customs Declaration Company. Please solve one problem." It turned out that Zhang Xinhua’s agent, Changxu Electronics, declared a ticket of equipment to Wujiang Customs. After the goods were inspected by Shanghai Customs, the system could not be released for a long time. As the equipment will be used in a new project of the company, the whole company and even customers attach great importance to it, and overseas engineers from the original equipment factory are also waiting in the company to assist in installation. Delivery one day late may cause customers to cancel their orders. Zhang Xinhua found the door with a try.

  After listening to Zhang Xinhua’s words, Ma Honglan grabbed the phone without saying anything, and told the relevant customs officers of the customs clearance department, who quickly contacted Shanghai Customs by telephone. At this time, the customs officers of Shanghai Customs were on their way off work and quickly returned to the customs after learning the situation. With everyone’s joint efforts, this batch of equipment was cleared and released that night.

  "Nowadays, trade protectionism is becoming more and more fierce, and a good business environment is extremely important for attracting investment. This incident makes us fully feel the enthusiastic service and efficient customs clearance efficiency of Wujiang Customs … …” This is said in the thank-you letter sent by Changxu Electronics to Wujiang Customs.

  For the "enterprise problem clearing" work, Wujiang Customs specially issued the "Implementation Plan of Enterprise Problem Clearing Mechanism", which made specific arrangements for the key issues, specific methods, internal mechanisms, feedback channels and work requirements of the enterprise problem clearing mechanism. At the same time, a closed-loop management chain of Wujiang Customs internal problems collection, registration, promotion and supervision, timely feedback and follow-up visit has been established. Put forward enterprise problems and clear "day — "Week" mechanism, that is, the on-site answer to the enterprise can not be solved overnight, and the solution that needs comprehensive consultation should not exceed weeks; At the same time, we have established and relied on the professional cooperation mechanism of this customs to integrate the new customs business, and established seven professional cooperation groups, including commodity inspection, animal and plant quarantine, health quarantine, and food and cosmetics safety, to provide effective protection for the enterprise problem clearing.

  Multi-channel unblocked problem feedback mechanism

  Suzhou hisilicon Co., Ltd. (hereinafter referred to as Haisi Company) is affiliated to Huawei Technologies Co., Ltd., and is mainly responsible for the import trade of Huawei chips. "In order to realize the localization process of chip manufacturing and save costs to a greater extent, in early May, Hisilicon proposed to export some high-end processing technologies. According to the export processing policy, the company must have the qualification of general customs certification or above, and the company is currently a general credit qualification, which does not meet the policy requirements of export processing, and it is urgent to obtain the qualification of customs certification enterprise. " Liu Xiaojian, head of the Credit Management Section of the Customs Enterprise Management Office of Suzhou Industrial Park, said.

  On May 7th, the Customs of Suzhou Park immediately went to the enterprise to conduct research and conduct on-site credit cultivation for the enterprise after learning the enterprise’s demands. On May 14th, the Deputy Commissioner in charge led a team to join the local government to go to Huawei’s headquarters for investigation, and quickly wrote an investigation report. At the same time, it reported the pain points and demands of the enterprise to Nanjing Customs, which was strongly supported by the leaders of the General Customs and the Enterprise Management Office. At the same time, the Customs of Suzhou Park appointed a special person to carry out seamless docking with the enterprise and cultivate it, doing its best to help the enterprise prepare for certification. On May 22nd, AEO Certification Group of Nanjing Customs carried out advanced certification for Haisi Company and passed it successfully. To this end, the enterprise presented a banner and medals made with the most advanced 7-nanometer chip in the world to the customs.

  Since the beginning of this year, Suzhou Park Customs has been guided by clearing the problem, constantly optimizing and smoothing the feedback mechanism of enterprise problem collection and research, and striving to solve the problems that enterprises care about the government. At the same time, actively promote the application of enterprise problem clearing system in this customs area, and guide enterprises in the jurisdiction to use the system through multiple channels.

  "Xiao Qingshan" is a volunteer service team composed of social forces such as customs officers and senior customs officers in Suzhou Park. The team makes full use of the advantages for customs groups and key enterprises to realize "zero distance" for answering questions for enterprises. "We have now set up 12 instant messaging groups, widely collecting daily problems of enterprises through WeChat, QQ and other channels, and focusing on answering questions on the backbone of customs business." Du Yang, the second-level sponsor of the Comprehensive Customs Business Department of Suzhou Park and the leader of the "Xiao Qingshan" volunteer service team, told the reporter that in order to make the enterprises in the jurisdiction make full use of the customs reform bonus, the team also actively assisted the local government to carry out research on key enterprises, tailor-made policy packages for them, and carried out "one-on-one" business guidance for pilot enterprises, trying to "find people when problems occur and find people to solve them" so that corporate problems can be "cleared" in the first time.

  From January to July this year, Suzhou Park Customs held 23 policy presentations and participated in more than 2,390 enterprises. Went to the enterprise for investigation 66 times, and accepted and solved 105 problems; Telephone, internet and other channels accepted more than 750 replies. "In addition to promoting the advanced certification of Haisi AEO, we have also solved a number of concerns of enterprises, industry associations and local governments such as the entry of Roche diagnostic serum and the import of used Philips medical equipment." Wang Yongmei, deputy director of Suzhou Park Customs Office, said.

Ministry of Agriculture and Rural Affairs: Scientific aquaculture can purify the ecological environment.

Conference site (Tang Shiying/photo)

Cctv news(Reporter Tang Shiying) At 10: 00 a.m. on February 15th, the State Council Press Office held a press conference. Yu Kangzhen, Vice Minister of Agriculture and Rural Affairs, and Zhang Xianliang, Director of the Fisheries Bureau of the Ministry of Agriculture and Rural Affairs, introduced the "Several Opinions on Accelerating the Green Development of Aquaculture" and answered questions from reporters. 

At the meeting, a reporter asked: "In recent years, some voices in the society have suggested that aquaculture has some negative effects on the environment. Excuse me, how does the Ministry of Agriculture and Rural Affairs view this issue? "

"We did learn that in some places, the relationship between aquaculture and water ecological environment was not handled very well, and aquaculture polluted the environment. Is it true that all kinds and methods of aquaculture will pollute the water ecological environment? Need scientific analysis. " Yu Kangzhen said that not all aquaculture varieties and farming methods will have a negative impact on the aquatic ecological environment, only high-density and unreasonable feeding farming methods will have a greater impact on the environment, and scientific and reasonable farming methods will not cause pollution to the environment. On the contrary, scientific and reasonable farming methods can also purify and repair the water ecological environment.

Yu Kangzhen introduced that according to the Bulletin of the First National Pollution Source Survey, aquaculture emissions are calculated by chemical oxygen demand and ammonia nitrogen, accounting for 4% of agricultural emissions. Most pollutants in aquaculture are organic substances such as nitrogen and phosphorus, which mainly cause eutrophication of water environment and have little impact on water body as a whole. In addition, filter-feeding fish such as shellfish algae in marine culture and silver carp and bighead carp in freshwater culture in China are all non-feeding aquaculture varieties. Among them, shellfish algae account for 83% of the total amount of marine aquaculture, and filter-feeding silver carp and bighead carp account for 25% of the total amount of freshwater aquaculture. These cultured varieties have good purification and restoration effects on the environment. It is estimated that in 2016, only silver carp and bighead carp culture can eliminate about 370,000 tons of nitrogen and 140,000 tons of phosphorus in water. 

The results of a consulting research project of China Academy of Engineering show that the algae culture of marine shellfish has an efficient "carbon fixation" function. Yu Kangzhen said that only marine shellfish culture can remove more than 1.2 million tons of carbon every year. "The contribution of marine shellfish culture in China to reducing atmospheric carbon dioxide is enormous. To make a metaphor, it is equivalent to afforestation of 500,000 hectares per year, and the ecological benefits are remarkable. "

Jiangsu was hit by a tornado. Big data reveals when and where tornadoes are prone to occur in China.

  China Weather Network News Affected by surface cyclones, severe convective weather occurred in many places in Jiangsu yesterday (July 20th), among which Suqian Shuyang and Lianyungang Guannan were even hit by tornadoes. As a small-scale weather system, tornado has a short life, but it is extremely destructive. It comes as soon as it comes, and people can’t avoid it. Is there a rule for tornadoes to follow? China Weather Network analyzes meteorological big data to reveal when tornadoes are most frequent in China and which areas are more prone to them.

  Tornadoes are extremely destructive and can blow cars and destroy houses.

  Tornado, as a kind of strong destructive convective weather, is a small-scale air vortex produced under strong unstable weather conditions. The central wind force can reach 50-150 m/s, and the diameter is generally between several meters and hundreds of meters.

  Tornadoes are generated and disappeared rapidly, often accompanied by strong convective weather systems such as thunderstorms, hail and heavy rain, which are extremely destructive. According to Fujita scale, the tornado strength is divided into six grades: EF0 to EF5, with EF0 being the lowest and EF5 being the highest.

  Tornadoes of EF2 and above are generally called strong tornadoes, and EF2 tornadoes will cause considerable damage, which may lead to the uprooting of trees; EF3 tornadoes often cause serious damage, and trains may be blown down. EF4 tornado may cause destructive damage, good brick-wood structure and frame structure houses may be destroyed, and some houses will be shoveled and leveled by Qi Gen; The damage caused by EF5 tornado is devastating. The house with frame structure may be thrown out together with the foundation, the reinforced concrete structure building will be seriously damaged, and the car may be blown away.

  Tornadoes have occurred in most parts of China, with the largest number in Jiangsu and Guangdong.

  Global tornadoes mainly occur in mid-latitude areas, and tornadoes occur every year in North America, Europe, Russian Federation, China, Japanese and Australian, among which the United States is the country with the most tornadoes, with an average of 1,141 tornadoes recorded every year (from 2000 to 2020), which is called "Tornado Kingdom".

  Tornadoes in China mainly occur in the eastern plain, and the middle and lower reaches of the Yangtze River are frequent areas. According to the statistical data of the National Climate Center from 1991 to 2020, there are 38 tornadoes every year in China, and there are more tornadoes in Jiangsu, Guangdong, Hubei and Anhui provinces, among which Jiangsu and Guangdong have the most tornadoes, with an average annual number of 4.8 and 4.3 respectively, followed by Hubei and Anhui, with two tornadoes.

  Strong tornadoes occur frequently in spring and summer in China, and most frequently in July.

  Spring and summer are tornado-prone seasons in China, and the number of tornadoes accounts for 92% of the whole year from April to August, with July accounting for the highest proportion, accounting for about 30%. Judging from the occurrence time of tornado of EF2 and above, it is also the most in July.

  According to the statistical data of "Temporal and Spatial Distribution of loong Tornadoes", there were 165 tornadoes of EF2 and above in China from 1961 to 2010, and the occurrence time was mainly from April to August. Looking at a single month, July was the most, accounting for 28% of the total number of the year, followed by April.

  In addition, the months of tornadoes in different regions are slightly different. South China frequently occurs from April to May, the middle and lower reaches of the Yangtze River frequently occur in April and July, North China frequently occurs from June to July, Northeast China frequently occurs from June to August, Southwest China mainly occurs from July to August, and Northwest China frequently experiences tornadoes in July.

  Tornadoes prefer the afternoon and the evening.

  In addition to seasonal differences, the time of the tornado’s haunting in one day also has certain rules, and the tornado prefers to "haunt" in the afternoon.

  According to the statistical data of "Temporal and Spatial Distribution of loong Tornado", from 1961 to 2010, tornadoes occurred from 12: 00 to 20: 00, accounting for 70% of the total number of tornadoes whose time records can be found. The reason for the high incidence in this period is that the atmospheric stratification is unstable after daytime solar radiation, and strong convective weather is most likely to occur, which is easy to promote the formation and strengthening of tornado weather system.

  In addition to the high-incidence period in the afternoon, the tornado often appears in the early hours of the morning. According to statistics, there are also 10 tornadoes generated from 0: 00 to 2: 00. Tornado occurred less in the morning, with the least occurrence from 10: 00 to 12: 00, only once.

  There are 38 tornadoes in China every year, with a maximum of 75 in 2005.

  Judging from the interannual changes, the periodicity of tornadoes is also obvious. According to the statistics of tornado data recorded from 1991 to 2020, there are an average of 38 tornadoes every year in China. There were relatively many tornadoes from the mid-1990s to the beginning of this century. There were relatively few tornadoes in the early 1990s and from 2006 to 2020. Among them, the number of tornadoes was the highest in 2005, reaching 75, and the least in 2020, only 13.

  What should I do if I encounter a tornado?

  Tornado is a kind of severe convective weather. After the tornado is formed, it usually lasts for ten minutes to several hours. Its attack range is small, but its destructive power is great. Once encountered, how should we defend ourselves?

  First, if you are at home, be sure to stay away from doors, windows and the outer walls of houses, and hide in the wall or small room opposite to the tornado. The basement or semi-basement is the safest place to avoid the tornado;

  Second, in the emergency of pole falling and house collapsing, the power supply should be cut off in time to prevent electric shock or fire;

  Third, when there is a tornado outside the field, you should look for low-lying ground nearby, but stay away from trees, telephone poles, billboards, fences, etc. to avoid being smashed, crushed or electrocuted;

  Fourth, when you encounter a tornado when you go out by car, you should drive in the opposite direction, or leave the car immediately and take shelter in a low-lying area.

How much automobile coolant is appropriate?

The standard amount of automobile coolant is usually in5 to 6 litersBetween, this is an ideal range. If the coolant is too much or too little, it will adversely affect the normal operation of the car.

It is very important to know the types and characteristics of coolant for maintaining the good operation of automobile cooling system. The following is an introduction to several types of coolant:

Alcohol-based coolant:

This type of coolant used ethanol as antifreeze. Although it is cheap and has good fluidity, its boiling point is low, it is easy to evaporate and lose, and its freezing point is easy to rise, so there is a risk of flammability. Because of these shortcomings, it has been gradually eliminated.

Glycerol coolant:

Glycerol-type coolant has the advantages of high boiling point and low volatility, is not easy to burn, and has low toxicity and corrosion. However, its disadvantage is that the effect of lowering freezing point is not good and the cost is relatively high, so only a few Nordic countries are still using it.

In addition to the above two types of coolants, there are other types of coolants, such as glycol coolants and water-based coolants. Choosing the appropriate coolant according to the specific needs and environmental conditions of the vehicle is very important for maintaining the normal operation of the automobile cooling system.

In daily maintenance, it is a key step to check the quantity and quality of cooling liquid regularly and supplement or replace it as needed to ensure the stable operation of automobile cooling system.
