Xinhua News Agency, Hanoi, July 12 (Reporter Sun Yi) According to the report of the Vietnamese Ministry of Health on the 12th, in the first half of this year, nearly 40,000 cases of dengue fever were diagnosed and 8 cases died in Vietnam. Since the beginning of this year, the epidemic situation of dengue fever in Vietnam has eased compared with last year, but it has just entered the high-incidence season of dengue fever and the epidemic has spread rapidly in the north of the country.

　　Ruan Wenyong, director of the Insect Research Office of the Central Institute of Malaria, Parasitology and Entomology in Vietnam, told the media that more than 1,100 cases of dengue fever were diagnosed in northern Vietnam in the first half of the year, an increase of 60% over the same period last year. The worst epidemic is in ha noi, where 823 cases of dengue fever have been confirmed this year, nearly 3.5 times the number of confirmed cases in the same period last year, but no deaths have occurred. The main reason is that the weather in ha noi is abnormal in recent days, and the rainfall after high temperature provides a good breeding environment for mosquitoes.

　　Ruan Wenyong said that abnormal climate is a major cause of the rapid spread of dengue fever. According to the past rules, there will be a peak of dengue fever transmission in Vietnam every four to five years. However, in recent years, Vietnam’s climate has become hotter and wetter, with abundant rain, which has led to mosquito infestation. In the past five years, the number of confirmed cases of dengue fever in Vietnam has been at a high level every year.

　　Dengue fever is an acute infectious disease caused by dengue virus, which is mainly transmitted by mosquitoes and is prevalent in tropical and subtropical regions. Typical symptoms include persistent fever, headache, muscle pain, joint pain, etc., which can cause death in severe cases.

　　In order to curb the dengue fever epidemic, the Vietnamese Ministry of Health advised people to clean up the garbage in the house in time, try to wear long clothes and trousers to prevent mosquito bites, and cooperate with the local health department to take disinfection measures. When you have fever and other related symptoms, you should go to a medical institution for treatment in time, and you should not treat them at home.

Public opinion is out of control.

Netizen’s hot comment: strict investigation and severe punishment!

A netizen from Anhui shared the experience that her medical record information was leaked. Just after giving birth to a child and returning home, a liar called her to say that there was a maternity allowance. Apart from hospitals and clients, who will have such detailed medical records and personal information as women?

The netizen from Zhejiang sent a soul torture: How did the patient’s medical records leak? Except for stars and important people, can ordinary people’s medical records be read casually?

For everyone’s questions, a medical staff from Beijing said: The system of Beijing Hospital is that the internal staff of the hospital can view the medical records of any department and any patient. Before, a patient in her hospital was transferred to ICU. In the afternoon, the head nurse checked the system and found that the patient had passed away.

Everyone’s views on the disclosure of patients’ medical records are surprisingly consistent. They hope to investigate and severely punish the staff involved, and they can’t always condone this kind of thing without moral bottom line.

Many parties responded and the people involved were arrested.

On December 13th, the relevant staff of Shunyi Hospital of Beijing Hospital of Traditional Chinese Medicine, which is in the center of the whirlpool of public opinion, publicly responded: from the evening of the 12th, the hospital started to investigate this matter, and is currently under further investigation. The final investigation results will be announced through the official platform of the hospital.

On the same day, the staff of the Shunyi District Health and Health Commission in BeijingThe latest response said that the relevant situation has been concerned and the local police have been involved in the investigation.

On the evening of 13th, according to the Beijing News, two people involved in leaking medical records have been found and handed over to the police. People familiar with the matter said,One of the two people involved is an employee of the hospital involved.The other person is a friend of the employee.At present, the employees involved have been suspended from practicing.The hospital is awaiting the results of further investigation by the police.

The relevant staff of the hospital involved confirmed that the medical records transmitted by the internet are indeed the real medical records of the hospital, and the follow-up hospital will further handle them according to the results of the police investigation.

On the morning of December 14th, Ping An Beijing issued a briefing:On December 11th, Fu took advantage of the convenience of working in a hospital in Shunyi District for the purpose of showing off., taking photos of a patient’s personal medical record and sending them to WeChat group, which leads to information diffusion and bad social impact. At present,Shunyi Public Security Bureau has placed Fu Moumou in administrative detention according to law..

Coincidentally!

In fact, the privacy leaks of patients, especially star patients, are not uncommon.

In 2018,Kenny Lin angered a medical institution and its medical staff in Weibo.It is said that the medical record information of his hospitalization was leaked, which caused concern.

In 2019,JJ LinWhen holding a concert in Zhenjiang, Jiangsu,Go to the hospital because of physical discomfort. That afternoon, his medical information was leaked.Even more exaggerated, the medical staff of the hospital also took turns lying on the bed he had used. At that time, it also aroused great public concern, and the hospital responded quickly, and all 11 medical staff involved were dealt with accordingly, and they were suspended for more than half a year, and this matter was calmed down.

In addition, some doctors said: more than a decade ago, there was no cross-departmental firewall in China.He witnessed some medical students and residents who opened and disseminated the medical records of the stars at will in the hospital..

Of course, such a thing is not exclusive in China. The above-mentioned doctor said that he used to work in pediatrics at the National University Hospital of Singapore. At that time, a local official asked the hospital for access to his medical records in the past three days.

According to the results,The official’s medical record has been turned over by dozens of medical staff.The number is far higher than the actual demand for medical services.And many staff members who open medical records have nothing to do with the patient..

Leaking patient privacy is a "red line"

In this regard, many netizens expressed doubts. Do you want to condone such bad behavior by checking and leaking patients’ medical records at will?

In fact, all countries have clear regulations and penalties for medical institutions and practitioners to disclose patients’ privacy in their practice activities.

As far as China is concerned, according to the provisions of the Civil Code,Personal information such as a person’s name, portrait, reputation, honor and privacy are protected by law.. Personal information shall not be illegally collected, used, processed or provided to others without the consent of the person or his guardian. ifMedical institutions and their medical staff who disclose patients’ privacy and personal information or disclose their medical records without patients’ consent shall bear tort liability..

It is also clearly stipulated in the Basic Medical Care and Health Promotion Law, which came into effect on June 1, 2021.medical and health care institutionMedical information security system and safeguard measures are not perfect,If the medical information is leaked, and the circumstances are serious, it may be ordered to stop the corresponding practice activities, and the directly responsible person in charge shall be investigated for legal responsibilities..

In addition, the ninth paragraph of Article 37 of the Law on Medical Practitioners also emphasizes:When a doctor divulges the privacy of a patient in his practice, causing serious consequences., will face a warning or order from the health administrative department of the people’s government at or above the county level.Suspension of practice for more than six months and less than one year, if the circumstances are serious, its practice certificate shall be revoked, and if the case constitutes a crime, criminal responsibility shall be investigated according to law..

And article 253 of the Criminal Law of People’s Republic of China (PRC),If the circumstances of disclosing medical information are serious, it may constitute a crime of infringing citizens’ personal information. If the circumstances are particularly serious, they shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years and fined..

Here, Xiao Bian reminds all medical colleagues that they must stick to their professional ethics bottom line, don’t do illegal and criminal things, leaking patient information is a red line, and don’t die. At the same time, I also hope that all hospitals can strengthen management and don’t have similar things again!

In order to speed up the innovation and development of Guangzhou’s digital economy, focus on improving digital productivity and explore the construction of a new digital economy ecology with data as the key element, the Guangzhou Municipal Government recently issued the Implementation Plan for Building a National Digital Economy Innovation and Development Experimental Zone in Guangzhou (hereinafter referred to as the "Plan"). The "Proposal" proposes that Guangzhou will take the lead in exploring new ideas, new models and new paths for the innovation and development of the digital economy, and build Guangzhou into an experimental field for the circulation of digital elements in Guangdong, Hong Kong and Macao, a source of national digital core technologies, and a new benchmark for the transformation of the global digital industry.

Goal: By 2022, Guangzhou’s software and information service industry revenue is expected to exceed 600 billion yuan.

According to the "Proposal", Guangzhou strives to build a policy and regulation system, a public service system, an industrial ecological system and a technological innovation system that are suitable for the development of digital economy through experimental exploration in about two years. The contribution rate of the digital economy to the regional GDP and the penetration rate of industrial digitalization are constantly improving. By 2022, the output value of the electronic information manufacturing industry in the city will exceed 280 billion yuan, and the income of the software and information service industry will exceed 600 billion yuan.

The docking mechanism of digital economy rules in Guangzhou, Hong Kong and Macao is basically perfect, and the innovative elements of digital economy are fully converged, smoothly flowed and deeply applied in Guangzhou, Hong Kong and Macao. New breakthroughs have been made in the efficient allocation of data elements and key technologies of digital economy. Guangzhou will be built into the core area of the National Digital Economy Innovation and Development Experimental Zone (Guangdong), and a number of innovative development experiences that can be replicated and promoted will be summarized, which will strongly support the construction of Guangdong-Hong Kong-Macao Greater Bay Area and lead the high-quality development of the national digital economy.

Key tasks: By 2022, the city has built a total of 38,900 5G base stations.

The Plan puts forward six tasks: accelerating the construction of new digital infrastructure, promoting the safe and efficient circulation of innovation elements, improving the construction of digital economy innovation system, enhancing the advantages of core industries of digital economy, accelerating the digital transformation of industries in key areas, and strengthening the supply of digital public services.

According to the Plan, Guangzhou should speed up the construction of new digital infrastructure. Building a high-speed intelligent network of all things. Build 5G SA (independent networking) in an all-round way, promote the construction of F5G (fifth generation fixed network), and explore and test 10 Gigabit access capability by using 50G PON (passive optical fiber network) technology. On the basis of taking the lead in realizing the commercialization of 5G, expand the test and construction scale of 700MHz band radio and television 5G network. By 2022, the city has built a total of 38,900 5G base stations, and built a high-reliability, low-delay and wide-coverage 5G network to continuously cover the city. Pre-emptively deploy the construction of transmission infrastructure such as the next generation Internet, and further enhance the end-to-end connectivity of IPv6 (Internet Protocol Version 6). Accelerate the construction of applied digital infrastructure in industries such as industrial internet and car networking, and promote the formation of industry public service platforms. At the same time, accelerate the upgrading of traditional infrastructure "wisdom+". We will comprehensively promote the construction of smart airports, smart waterways, smart ports and smart city rail transit, accelerate the intelligent transformation of Guangzhou Baiyun Airport’s construction, operation and management in the whole life cycle, support Nansha Port to build a fully digital, intelligent and unmanned Bay Area demonstration port, and build a national smart city rail transit benchmark demonstration.

It is worth mentioning that in terms of the circulation of innovative elements, Guangzhou should explore the establishment of a government "chief data officer" system to promote the innovation of public data application scenarios. In the fields of population management, financial services, medical and health care, education, transportation, biological safety, etc., we will co-ordinate and organize the development and utilization of public data resources, establish a list of development and utilization directories, and clarify border conditions and regulatory measures. Explore the establishment of a sandbox experimental zone for data circulation and governance, and carry out pre-research on relevant laws and regulations such as data confirmation and personal data protection. Accelerate the legislative work in the field of digital economy and establish a full-chain system of data resources.

At the same time, we will strive for national support to implement cross-border open sharing and security management of data in Guangzhou, Hong Kong and Macao, take the lead in exploring the circulation rules of data elements in Guangzhou, Hong Kong and Macao, and promote the full convergence, smooth flow and deep application of data resources in Greater Bay Area.

Technical research: concentrate on the research and innovation of general technology based on digital economy

According to the "Program", Guangzhou should strengthen key technical research in key areas. Concentrate on the research and innovation of basic general technology, cutting-edge subversive technology and asymmetric technology of digital economy. We will continue to promote the implementation of research and development plans in key areas, and strive to break through key core technologies in key areas such as integrated circuit manufacturing equipment, materials and processes, basic software and industrial software.

In the key areas, it is emphasized that Guangzhou should explore the development of new integrated circuits such as FDSOI (fully depleted silicon on insulator technology) and heterogeneous integration. Support large industrial software enterprises to break through key core technologies such as CAD (Computer Aided Design), CAE (Computer Aided Engineering) and EDA (Electronic Design Automation). At the same time, accelerate the construction of major carriers and pilot demonstrations. We will comprehensively promote the construction of the national new generation artificial intelligence innovation and development pilot zone, the national artificial intelligence innovation and application pilot zone, and the national blockchain development pilot zone, and create a source of artificial intelligence and blockchain technology innovation, a new highland for agglomeration and development, a key area for open cooperation, and an experimental field for institutional reform.

Among them, Guangzhou should focus on breaking through the design of high-end general-purpose chips in the field of integrated circuits, vigorously develop the third-generation semiconductor chips, proactively lay out millimeter-wave chips and terahertz chips, give priority to the development of characteristic process chip manufacturing, support advanced process chip manufacturing, and actively promote the manufacturing of mixed digital and analog chips. Accelerate the construction of the second phase project of "Guangdong Core" in Guangzhou, and promote the IC design, packaging and testing enterprises to become bigger and stronger. Take the lead in implementing the national action plan for ultra-high definition video industry, plan to build the display capital of the world, and provide the hardware foundation for building the national ultra-high definition video application demonstration zone and content production base. In the field of smart cars, Guangzhou will promote the research and development and industrialization of high-precision sensors, car-level chips, intelligent operating systems, intelligent terminals, intelligent computing platforms, information security, high-precision maps (positioning) and other products.

The "Proposal" proposes that Guangzhou should strengthen the supply of digital public services. Among them, the digital government should accelerate the iterative upgrade. Through trusted identity, electronic license sharing, cross-departmental and cross-regional common maintenance and verification of government service data, materials, running, time limit and links will be reduced to the maximum extent, and the government service brand of "one network for running and the whole city for running" will be built, and the urban operation management center of "Sui Zhi Guan" will be built.

In terms of building a digital base for smart cities, Guangzhou proposes to build and deploy an urban brain neural sensing network with sensitive perception, interconnection and timely decision-making. We will further promote the development of intelligent transportation, speed up the two-way communication between Internet data and urban intersection signal control systems, implement flexible adjustment of traffic control with traffic flow, build a parking information platform, and improve the service levels of parking space inquiry, map navigation and parking space reservation. Actively promote the construction of smart light poles and accelerate the transformation of existing light poles with "one pole for multiple purposes".

Drinking tea is a quiet activity, and drinking milk is beneficial to human health, but milk tea is a typical fast-moving product. People walked into the tea shop while saying that they would never drink milk tea again. What is the magic of milk tea that can’t escape the "law of true fragrance" that makes young people flock to it? Hong Kong-style, table-style, low-sugar, milk-covered … What’s in all kinds of milk tea? What is the impact on health?

First, the "milk" in some milk tea is to use non-dairy creamer instead of milk, that is, "fake milk". The main components of non-dairy creamer are hydrogenated vegetable oil, glucose syrup, sodium caseinate and sodium aluminosilicate. Among these components, partially hydrogenated vegetable oil contains trans fatty acids. Scientific research shows that the intake of trans fatty acids is positively correlated with the incidence of cardiovascular diseases. Dietary Guidelines for China Residents suggest that the daily intake of trans fatty acids should not exceed 2g. Milk tea made of non-dairy creamer contains 0.5g to 2.7g of trans fatty acids per 300ml (equivalent to a medium cup of milk tea). Drinking milk tea for a long time will increase the risk of cardiovascular diseases.

Second, milk tea is exciting because of "caffeine". Caffeine generally exists in coffee, strong tea and other beverages, and the single caffeine intake of healthy adults is best not to exceed 200mg. The average caffeine content in milk tea on the market is 270 mg/L.

Third, the sugar content is high. The sugar content of a cup of milk tea is about equal to that of a bottle of cola. Even milk tea with low sugar, no sugar or no sugar has sugar. The Dietary Guide for China Residents stipulates that "the daily sugar intake should not exceed 50g, and it is better to control it below 25g", while the sugar content of milk tea with normal sweetness reaches 35g per cup.

Fourth, milk tea tastes good because of its high fat. Fat can bring good flavor and taste, but excessive fat intake will lead to obesity. In milk tea with milk cover, the fat content is particularly high, with an average of 7g/100mL. The recommended daily intake of fat for adults is less than 60g. Drinking such a cup of milk tea is equivalent to eating the fat of two meals.

There are many hazards of drinking milk tea for a long time, such as coronary heart disease, osteoporosis, obesity and cardiovascular disease. However, these diseases will only appear if you drink too much for a long time. Of course, you can drink milk tea, but you should be careful not to be greedy.

This article is scientifically checked by Song Bingbing, a national registered dietitian and health manager.

　　A physical examination package with a group purchase price of 1056 yuan has the embarrassment of "finding the disease in the morning and recovering in the afternoon".

　　In November this year, Ms. Chen from Shanghai bought a health check-up package for middle-aged and elderly people with a price of 1056 yuan online, and made an appointment for a physical examination at the store by telephone according to the group purchase instructions. The contents of this physical examination include internal medicine, surgery, tumor markers, 11 items of liver function and 3 items of renal function.

　　"On the website, the cheapest medical examination package is only three or four hundred yuan, the expensive one is 1,500 yuan, and the middle-aged and elderly package of 1,056 yuan is above average." Ms. Chen is 32 years old. She told reporters that she has compared the packages of many well-known medical institutions such as ikang, Mei Nianda Health and Ruici Physical Examination. The price of 1,056 yuan does not belong to the ranks of "low-cost medical examination" in any medical examination center. "I specially chose expensive ones to make the institutions earn enough money, so I should never be cheated again."

　　However, later facts proved that she was wrong.

　　The physical examination report is inconsistent with the examination results of the top three hospitals.

　　During the physical examination, the "doctor" who did the neck B-ultrasound told Ms. Chen that her thyroid was "bad" and had serious inflammation. The B-ultrasound report showed that there was a serious "diffuse echo" in the thyroid gland. The "doctor" reminded Ms. Chen, "Go to Shou Feitai on the first floor and have a blood test of thyroid function. You don’t need to draw blood again, just pay."

　　During the surgical examination, the surgical "doctor" touched the thyroid gland of Ms. Chen’s neck and reminded her again, "You can already feel the nodule here, at least you have thyroiditis. Go to the first floor to pay for it and check the thyroid function."

　　This is not the first time that Ms. Chen has paid for the blood test of "thyroid function" in the United States. Last November, in the same health store, B-ultrasound showed that she had "thyroid nodules". To this end, she paid about 200 yuan’s thyroid function examination fee after the discount.

　　"Every time I say that there is a problem with the thyroid gland, check the function. If the blood is fine, it doesn’t matter." Two blood test reports of Ms. Chen showed that her thyroid function was normal.

　　This year, because of the "diffuse echo" accompanied by thyroid nodules, Ms. Chen went to the endocrinology department of a well-known 3A hospital in Shanghai for re-examination after the physical examination that morning. After introducing her physical examination to the doctor, the doctor gave a diagnosis of "thyroiditis" and asked her to do another B-ultrasound and thyroid function examination in the hospital.

　　This time, the doctor who did the B-ultrasound told her, "Are you thyroiditis? Congratulations, you have recovered. " Ms. Chen once again asked if her thyroid nodules were still there. The doctor of B-ultrasound told her with great certainty: "From the imaging point of view, your thyroid gland is all normal, without nodules and inflammation."

　　The blood test report is also the same result, and everything is normal. "I can’t believe that the surgical experts in the physical examination center in the morning can even find out that I have a big nodule; In the afternoon, the B-ultrasound of the regular hospital showed no nodules. " It is worth noting that when Ms. Chen told her family about her experience, her father, mother, father-in-law and mother-in-law all replied that they had also encountered the above situation. Four elderly people have never had thyroid diseases, and all the medical examination packages use the 1056-yuan beauty health package purchased online by Ms. Chen, and all of them pay for the thyroid function on the spot during the medical examination.

　　A few days ago, the reporter visited the Mei Nianda Health Check-up Center in Shanghai Pudong Changhang Hospital mentioned by Ms. Chen, and saw a long queue for paying fees on the first floor. All the people in the queue buy temporary physical examination items after purchasing the physical examination package, and six of the nine people pay for thyroid function examination.

　　A similar situation occurred in many medical institutions.

　　Coincidentally, the same problem happened to Ms. Lin and her colleagues in Luoyang, Henan Province, and the thyroid function test was the one that broke the problem.

　　"You have a big problem, diffuse thyroid disease." Ms. Lin still remembers the diagnosis given by the B-ultrasound "doctor" on the spot when she was examined at the Mei Nianda Health Physical Examination Center in Luoyang. The situation she encountered was almost exactly the same as that of Ms. Chen in Shanghai. The "doctor" reminded her, "You just took blood, so go and pay the money. You don’t need to take any more blood. Have a test."

　　"At the payment office, I met five or six colleagues who came to add money to do thyroid function (examination). It didn’t feel right." After consulting her brother who works in the county people’s hospital, Ms. Lin gave up the payment and went to the county hospital for re-examination the next day. The hospital B-ultrasound and blood test report showed that Ms. Lin’s thyroid gland was all normal.

　　According to "China Consumer News", in June this year, Ms. Shi, a citizen of Nanjing, found that "the right thyroid nodule is accompanied by calcification, and there is a hypoechoic nodule in the right thyroid lobe, the size is about 10mm×8mm". But later, when Ms. Shi was reexamined in jiangsu province hospital, the B-ultrasound showed that "bilateral thyroid glands were normal in shape, with clear boundaries, smooth surface and normal internal blood flow, and no obvious abnormal lymph images were found in bilateral necks".

　　In response to this problem, the medical examination institution in Nanjing replied that "the doctor was sick and paralyzed and returned to his hometown". In response to the error in the medical report, the person in charge said that "it may be caused by many factors such as doctor technology and medical equipment problems".

　　The reporter noted that the chaos in the medical examination market has already become the focus of public opinion. Previously, the "Analysis Report on the Development Prospects and Investment Forecast of Health Examination Industry" released by Forward-looking Industry Research Institute showed that the health examination industry in China grew to 94 billion yuan with a growth rate of more than 25% in 2015, which was more than twice the growth rate of 29.5 billion yuan in 2010. The compound growth rate of the industry in the five years from 2011 to 2015 reached 21%, which was higher than that of the entire medical service industry. It is estimated that the scale of the health examination market in China will reach in 2018.

　　Do medical institutions earn money by adding items?

　　"Some institutions rely on capital to promote physical examination business. It sells physical examination as a product, collects money by project, and gives commissions according to the total amount of fees." The relevant person in charge of the physical examination center of a public hospital in Shanghai told the reporter that taking the physical examination project of middle-aged and elderly people as an example, the products purchased by private institutions at a price around 1000 yuan may cost 1,200 yuan to 1,300 yuan in public hospitals. "It can’t lose money, so he wants you to add projects, and it is most appropriate to make efforts on the A-level and liver-level."

　　According to the person in charge, thyroid diseases mostly occur in women aged 30-50, and the incidence of liver diseases is higher in men, and both diseases have the characteristics of "B-ultrasound+blood test". "The package of medical institutions generally only contains B-ultrasound examination, and blood test items are purchased on site."

　　The reporter interviewed the relevant person in charge of the Health Marketing Department of Mei Nianda. The person in charge responded that the agency has a strict review system for the customer’s physical examination report, and customers can consult and answer questions by telephone or online according to the process. In response to the question of "adding thyroid function", the person in charge said, "From the perspective of disease screening, thyroid ultrasound and thyroid function are indeed more suitable for combined detection and cannot replace each other."

　　"Thyroid function should be a must-check item, and it is not necessary to have surgery or B-ultrasound abnormalities to do thyroid function (examination)." The person in charge said that the incidence of thyroid-related diseases is relatively high at present, so it is suggested that medical examination consumers list this as a "must-check item".

　　The reporter noted that in recent years, complaints and disputes against private medical institutions have continued. Some people took the medical examination institution to court because the medical examination failed to detect cancer, and some people claimed compensation from the medical examination institution through the Consumers Association because of the malicious addition of the medical examination. "Can’t find the problem, to complain; After finding out the problem, there is no problem after being examined by a regular hospital, and you have to complain. " The person in charge of the medical examination department of the above-mentioned public hospital told the reporter. With the improvement of people’s living standards, physical examination has become an important means of health management for many people to "check out their own pockets" every year. However, physical examination is not a formal treatment after all, and it can only play a role of prompting and reminding. "There will definitely be inaccurate situations, and eventually we will go to a regular hospital for review and follow-up."

　　The 2017 annual report released by Mei Nianda Health in the middle of this year shows that physical examination service is the main business of Mei Nianda Health. In 2017, this business achieved an operating income of 6.142 billion yuan, accounting for 98.54% of the total revenue and a gross profit margin of 46.61%.

　　China Youth Daily Zhongqing Online Reporter Wang Yejie

Li Yanhong, founder, chairman and CEO (CEO) of Baidu Company

　　　　　　　　The Paper (www.thepaper.cn) learned that on the morning of April 24th, Li Yanhong, founder, chairman and CEO of Baidu Company, was invited to give a speech at the CSRC. Prior to this, on February 10th, Ma Yun, Chairman of Alibaba’s Board of Directors, also gave a speech at the CSRC. At that time, the report was the first lecture in a series of lectures on frontier issues sponsored by the Innovation Business Supervision Department of the CSRC. The following is a quick reading of the essence of Li Yanhong’s speech at the CSRC:

Baidu hopes to return to domestic listing.

　　　　　　　　This year is the 10th year of Baidu’s listing. We listed on NASDAQ on August 5th, 2005. Many people have the impression that the stock rose by more than 350% on the day of listing, and many investors were very happy. When we went public, our market value was 800 million dollars. Today, 10 years later, it is close to 80 billion dollars, so it is 100 times the return in 10 years.

　　　　　　　　In the past ten years, Baidu’s reputation on Wall Street is still good. Of course, I have also expressed on various occasions that I hope that Baidu will have the opportunity to come back, go public in China, or benefit China investors in some other way. Because our market is in China, users are in China and customers are in China, we also hope that our shareholders and investors can be in China.

Gold Venture Portfolio = Baidu Technology+Tencent Products+Ali Operation

　　　　　　　　Compared with companies such as Ali and Tencent, the main feature of Baidu is that technology is something that we attach more importance to and are better at. As we all know, the entrepreneurial craze is very hot now. There are various VCs stationed in the coffee shop next to our building for a long time, talking with our employees there every day, trying to "fool" them out and start a business.

　　　　　　　　What is a golden venture portfolio? It is a person who is engaged in technology in Baidu, plus a person who is engaged in products in Tencent, plus a person who is engaged in operations in Ali. It is the easiest for such a person to get venture capital.

China’s logistics efficiency is low, so technology can be used to improve efficiency.

　　　　　　　　I saw a figure that the overall logistics in our country is actually very inefficient, and the logistics cost accounts for about 17% of China’s GDP. More than 40% of the trucks we run on the highway are empty. They are available from Beijing to Shanghai, but they are out of stock when they return from Shanghai, but there are still costs.

　　　　　　　　How to achieve refined operation? How to realize scientific scheduling? How can we make all the trucks have goods to pull?

　　　　　　　　People in Beijing may often see people wearing Baidu takeaway clothes on the street, that is, knights. In fact, these seemingly hard-working jobs are actually not low in technical content. For example, I can tell you where to stay at 11: 00 a.m., which order to pick up first, which order to pick up later, which knight to pick up this order, and which orders can be merged together … These are very complicated calculations, and when the scale is large enough, these efficiency improvements will lead you to become more and more competitive.

I don’t have to sell Baidu shares for the next three to five years.

　　　　　　　　In 2013, I made up my mind to say that we should transform from PC Internet to mobile Internet. We have to pay a price for this transformation, and this price is not small. Before the transformation, our operating profit rate was 53%. Two years later, when the transformation was completed, our operating profit rate dropped to 29%.

　　　　　　　　The older the company, the more afraid it is to make such a decision. Because its decision makers are often not founders, but tend to be professional managers to be the CEO of the company. These people may leave after five years or even a shorter time. He worked for a year, and once the profit rate dropped by five or ten points, the board of directors fired him.

　　　　　　　　As a founder, I think I will still be in this company in five or ten years. Even if I don’t work in the front line, my biggest interest is still the long-term interest of the company. I don’t have to sell Baidu shares in the next quarter, or in the next three to five years.

The mobile Internet is a gradual improvement, not a subversive revolution.

Speech scene

　　　　　　　　Baidu’s current revenue from mobile phones also exceeds that of PCs. But this success does not mean that we are safe. The next thing we should consider every day is, although everyone is used to searching on mobile phones, is it still so important? Will search become less important with the development of mobile Internet? To raise this issue to a higher level is the change from PC Internet to mobile Internet. Is it a qualitative change or a quantitative change? Is it revolution or improvement?

　　　　　　　　My answer is: it is an evolution, not a revolution. We see that today’s Internet companies, the vast majority of the largest Internet companies have been produced in the PC era, and they have already made corresponding scales in the PC era, and then they will further move the original products to the Internet. But even if it is a gradual change and improvement, as I just said, we still need to pay a great price, and it will take a long time to realize the transformation.

　　　　　　　　An Internet company is at the forefront of the wave of technological revolution, and it is so painful and costly to make a slight turn and change direction, so it is really more difficult for traditional industries.

Traditional industries should make up their minds to pay the price to embrace the Internet.

　　　　　　　　In the past two years, we have seen that no matter what industry people are engaged in, they have really begun to seriously think about what I do has to do with the Internet, how can I embrace the Internet and how to do things by the Internet.

　　　　　　　　Including our government. In this year’s government work report, the Internet, cloud computing, big data, internet finance and so on have been mentioned countless times, as well as the "internet plus". When the Internet is combined with any traditional industry, there will be many opportunities.

　　　　　　　　I also see that the overall macro situation in the past two years is very beneficial to both Internet companies and traditional enterprises. Although the downward pressure on the economy is relatively great, there are more opportunities than difficulties if we can really study and make great determination to embrace the Internet.

China’s traditional media and retail industry are not determined enough to embrace the Internet.

　　　　　　　　What industries have the Internet subverted? A typical example is the media. Now the internet has become our main source of information, not TV, newspapers, magazines and so on. Last year, Zhang Ruimin of Haier Company also said that Haier would not put advertisements in newspapers and magazines in the future. This is an obvious sign that the media has indeed undergone a qualitative change. And our traditional media, in fact, is not fast enough and resolute enough to embrace the Internet. So now their influence is declining and their market share has been greatly affected.

　　　　　　　　The second industry that has almost been subverted is the retail industry. When we go to offline physical retail stores, we will find that there are very few customers, but e-commerce is booming and developing very fast. At present, the proportion of online retail in China and the United States is almost the same, but the annual growth rate of online retail in China is 50%, and that in the United States is 15%. Therefore, we can see that the impact on the retail industry in China in the future is far greater than that on the retail industry in the United States.

Artificial intelligence will bring convenience to human life.

　　　　　　　　The popular Kingsman is a little worried about the meaning of artificial intelligence technology. The characters in the movie can control people’s emotions through mobile phone chips. In the industry, founders of technology companies such as Bill Gates of Microsoft and elon musk of Tesla have publicly reminded people to pay attention to the dark side that artificial intelligence may bring. My position is more optimistic. At present, artificial intelligence brings us more convenience and efficiency, and it will always be like this in the foreseeable future.

　　　　　　　　Working in the CSRC, you will often check the information of various companies, and you should be very familiar with search engines and very dependent on them. But we think there is a more exciting possibility in the future. Baidu in the past can tell you how many dollars 108,000 yen is equal to and what the weather will be like tomorrow. Now and in the future, Baidu can meet more needs, such as which airport I am going to, and set it for me at 4 pm; At 8: 30 in the evening, I want to watch Speed and furious 7, and I want a seat in the fifth row. Book it for me. I will go on a business trip the day after tomorrow and what hotel I will stay in, all of which can be done. It can understand your words and it can do it.

　　Affected by the epidemic, children are taking online classes at home, which unexpectedly gives parents an opportunity to understand their children’s classroom performance. When they saw their children swaying and looking around in class, some parents were in a hurry and even said: Is the child suffering from ADHD? On related issues, the Economic Daily reporter invited Wang Fang, the attending physician of the Department of Psychiatry of Beijing Children’s Hospital, to answer questions for everyone.

　　Some parents have observed that children can’t be quiet when they need to be quiet, such as walking around in class, or climbing up and down, or even like "perpetual motion machine", "as long as they are awake, they keep moving"; Although some people can sit in their seats, they have a lot of small movements, such as kicking and shaking their bodies. Some people have short concentration time, often stay in a daze in class, and even play with toys for only a few minutes and then quickly change to a toy; Some are easily distracted and easily influenced by the external environment; Careless, often careless in study; Avoid tasks that require high concentration, such as homework.

　　However, is it that a child is ADHD as long as he has the above symptoms?

　　"In fact, it is not. To judge whether a child has ADHD, it is necessary to comprehensively evaluate the child’s age, development stage and other factors." Wang Fang pointed out that most people think that ADHD means too much activity, but in fact this view is one-sided. The full name of ADHD is "attention deficit hyperactivity disorder", which is a disease characterized by inattention and excessive activity.

　　"Children’s attention is constantly changing with age. The average attention time of children aged 3 to 6 in kindergarten is 5 to 10 minutes, and they can concentrate for about 20 minutes when they first enter primary school. In addition, when faced with more than two things, children have the problem of attention distribution. For example, there are toys, comics and other things that children are more interested in on the table. When children write homework, they are easily attracted by these things, and there is a problem that they cannot concentrate on their homework. " Wang Fang said.

　　Wang Fang believes that in combination with these laws of attention, it is suggested that children should also set up a special learning environment at home. There should be no distractions on the desktop, and the class time should be arranged reasonably to achieve a combination of work and rest, so as to ensure full attention in class.

　　"Parents should not worry too much about their children’s academic performance. Don’t worry about whether their children have ADHD just because they can’t sit still in an online class or because they are in a daze when they write homework one day. However, if you find that your child often has the above-mentioned multiple performances at home, and the teacher usually reflects that the child has hyperactivity or attention problems, you need to go to the psychology department and other related majors for treatment. The doctor will judge whether the child has ADHD and intervene as soon as possible. Don’t let the symptoms of ADHD have a serious impact on the child’s study and life. " Wang Fang said.

　　Cctv newsOn April 23rd, Li Xinggan, director of the Foreign Trade Department of the Ministry of Commerce, introduced that many new changes have taken place in the international market in the past three years. One of the important changes is that more and more consumers around the world are accustomed to online shopping. Through cross-border e-commerce platforms, people can buy all over the world without leaving home. At present, all countries in the world are vigorously developing cross-border e-commerce. According to the WTO report, global B2C cross-border e-commerce will maintain a growth rate of 27% by 2026. In recent years, cross-border e-commerce in our country has maintained a rapid development momentum, which has increased nearly tenfold in five years. In the first quarter of this year, it continued to maintain a high-speed growth momentum.

　　Cross-border e-commerce is a growing point of foreign trade growth. Around the development of cross-border e-commerce, we will do the following four things:

　　First, develop "cross-border e-commerce+industrial belt". Relying on our country’s 165 cross-border e-commerce comprehensive test zones, combined with the industrial endowments and location advantages of various places, we will promote more products with local characteristics to better enter the international market. That is to say, while doing a good job in consumer-oriented B2C business, we will also vigorously support our traditional foreign trade enterprises, expand sales channels, cultivate brands and expand trade scale through cross-border e-commerce, especially expand the scale of B2B trade and service capabilities for enterprises.

　　Second, build an online integrated service platform. In recent years, various comprehensive test areas are actively promoting the construction of online integrated service platforms, and the concept is "let enterprises run less errands and let data run more". At present, there are more than 60,000 cross-border e-commerce enterprises served by these platforms, which is about 60% of the national cross-border e-commerce enterprises. It is also necessary to support and guide these cross-border e-commerce comprehensive test areas, further optimize the functions of service platforms, and guide overseas warehouse enterprises to dock online comprehensive service platforms. We strive to integrate the functions of customs clearance, taxation, finance and overseas warehousing, and realize the "one-stop access" comprehensive service, so that such a convenient integrated service can benefit all cross-border e-commerce enterprises.

　　Third, improve the assessment, promote excellence and help the strong. According to the requirements of the State Council, starting from 2021, we will carry out the assessment of the comprehensive test area together with relevant departments. This year, we will continue to optimize and adjust the assessment indicators in combination with the new characteristics of cross-border e-commerce. Through the assessment, we will guide the comprehensive test area to optimize the development environment, enhance the innovation level, accelerate the cultivation of a number of key enterprises, and enable outstanding enterprises to grow up better and faster, thus enhancing international competitiveness. At present, we are also preparing for the work promotion meeting of our national cross-border e-commerce comprehensive test area, exchanging local experiences and sharing effective practices, so as to better play the leading role of the excellent comprehensive test area.

　　Fourth, guide compliance management and prevent and control risks. Actively cooperate with China National Intellectual Property Administration, speed up the introduction of guidelines for the protection of intellectual property rights of cross-border e-commerce, help cross-border e-commerce enterprises understand the intellectual property rights in the target market, and do their homework in advance. As we all know, the protection of intellectual property rights at the national level has been increasing in recent years. In the field of cross-border e-commerce, we should set an example to protect intellectual property rights, put an end to counterfeit and shoddy products, and make cross-border e-commerce platforms and enterprises in China the base camp of "authentic, excellent and beautiful" products. At the same time, let cross-border e-commerce platforms and cross-border e-commerce enterprises become spokespersons for fast fashion consumption, thus attracting more consumers, especially young consumers, and fully protecting the legitimate rights and interests of global consumers.

Original title: Experts comment on the dark horse masterpiece "Keep you safe": the highest comedy is to perform real life.

Wen Shu Zhou Su (member of Chinese Literary Critics Association, deputy editor of Beijing Normal University Press, president of higher education branch)

Special feature of 1905 film network The realistic comedy film directed and starring has won nearly 350 million box office less than 10 days after its release, and has become a dark horse masterpiece of domestic films in the post-Spring Festival. The film tells the story of Wei Ping-an (Dapeng), a middle-aged man who went to prison for his friends out of loyalty. When he was a cemetery salesman after he was released from prison, he set foot on a rugged and difficult road to redress the wrongs for his dead client Han Lu (ornaments). In the end, Wei Ping-an fulfilled his promise to customers and also completed the redemption of his unbearable life. The film’s solid and close story, exquisite and realistic star-studded acting skills, profound and thorough social metaphors and warm and sincere moving emotions bring the audience a "warm realism" viewing experience with tears in laughter. On the whole, Keeping You Safe embodies exquisite and profound creative skills in three aspects: narrative completion, role shaping and emotional resonance, which can almost be called the pinnacle of Dapeng’s "directing+acting" series in recent years.

First, the presentation of mature narrative ability

In terms of narrative completion, "Keep You Safe" has achieved "telling a story well". In the past, Dapeng’s "director+starring" films often chose to "collage" stories with slightly blunt highlights of subculture, which was a bit "overexertion" because of their eagerness to achieve success (for example); Or series films with pure blood "feelings" clues, which are slightly "impulsive" due to lack of rationality (for example).

In terms of narrative skills, Keep You Safe has truly realized the mature transformation of Dapeng from a "cyber-big" director to a film director — — With rational and sophisticated narrative techniques, he chose the core clue of "seeking the truth" throughout the film, and quickly inspired the audience to produce "one-of-a-kind effect" from a limited narrative perspective; The film strictly follows the mature narrative law of commercial films, and promotes the story in the closed loop of plot design, logical presentation and echo. For example, in the scene of "Escape from the Chamber of Secrets", it not only successfully creates the atmosphere of many classic horror films, but also smoothly grafts into the comedy film "One Stop, One Meal" to adjust the audience’s mood freely, reflecting the skillful control of the film’s rhythm relaxation.

The film keenly uses "cyber violence", the core topic that causes people’s emotional explosion, to achieve the audience’s emotional resonance and value recognition of the work. For example, through Wei Ping’s sister (decoration), she uttered the thought-provoking words — — When you open your mouth and say that a woman is a lady, whether she is her or not, she is already. Reality is always more bizarre than the plot that the screenwriter came up with. In the film, Wei Ping-an was also infinitely distorted by online rumors in the process of clearing Han Lu’s grievances. For example, Wei Ping-an originally experienced that "his brother’s daughter-in-law was sleeping, and he helped his brother to fight each other", but after the amplification of the network, it became the absurd rumor that Wei Ping-an "slept his brother and then beat his brother’s daughter-in-law", which condensed the limit of "laughter" bred by extreme drama contrast.

Furthermore, the film reveals a more profound "human nature" topic behind the cyber storm — — The melon-eating spectators hiding behind the screen actually only want to see the "truth" they want to see; When people see that others are better off than themselves, there will be a kind of "malicious" speculation in human nature instinct. For example, in the film, when people learned that Han Lu, a young woman, had donated more than 1 million yuan naked to the welfare home before her death, they aroused the great imagination of "a villain’s heart is a gentleman’s belly", and people were waiting for the "black belly" answer they wanted behind the question of "why did she earn so much money". Just like the final ending in the novel Malicious, when Wei Ping-an finally caught the rumor monger in the film, he found that the source of this "malicious" answer, although disgusting to outrageous, was so simple and ridiculous.

It is through these "reasonable" rhythms and "reasonable" emotions which are different from Dapeng’s previous works that the film achieves the "reasonable" degree of story completion, thus truly enhancing the "real arrival rate" of the works’ thoughts to the audience. The realm of "reasonableness" achieved in film narration is particularly commendable among many domestic films that pursue short, flat and fast commercial returns.

Second, the role of three-dimensional shaping control

The plump three-dimensional presentation of characters and the extremely real "sense of hierarchy" in acting are another outstanding creative advantage of Keep You Safe. The success of this role-building is mainly reflected in the outline of the character’s pre-history and the psychological presentation of the role.

First of all, focus on Wei Pingan, the protagonist played by Dapeng. Behind his seemingly idle external behavior, he is actually full of bitter life ups and downs. For example, why did he keep his promise in the film and help a dead person to wash away seemingly meaningless online grievances? Why can’t you turn a blind eye and do what you want and finish the work of moving the grave? A large number of prehistory hooks at the front end of the film echo each other with the carefully designed egg plot at the end of the film, giving a secret answer: It is precisely because Wei Ping’s family life is not perfect that he unconsciously projects his heart into the lives of Han Lu and his lover, hoping that their spirit in heaven will replace him to get a happy "good end".

For another example, Wei Ping-an’s motivation to make money desperately is clearly explained in the film: It is precisely because his only daughter, Wei Moli, left a huge birthmark on her leg because of Wei Ping-an and his divorced ex-wife that Wei Ping-an tried his best to earn huge medical expenses, hoping to make up for her daughter’s more dignity. However, because of Wei Ping ‘an, her daughter was photographed with a birthmark on her leg by campus bullying, and Wei Ping’s most concerned "scar" was completely uncovered. Dapeng performed that kind of heartbreaking despair. Because he couldn’t go back to protect his daughter, his acting skill of beating the window glass painstakingly touched countless audiences. It was a true and simple emotional expression of a father, and he performed the helplessness and despair of "the collapse of an adult in an instant". The window glass he beat was like the shackles of life that he couldn’t break through at that time, and the full three-dimensional sense of character hierarchy was interpreted by Dapeng.

Secondly, Dapeng accurately designed the image of Wei Ping-an, the role he played. Green hair, cheeks painted red, messy and untidy image, and weird and unruly body language all form intertextuality with the tragic classic clown image played by Phoenix in the film The Clown. The sense of loss that nobody understands in a busy city, as well as the fact that after finally doing a good thing at the end of the film, Wei Ping-an saw the "666" fireworks scheduled by Han Lu before his death, with tears in his eyes and subconsciously nodded his head. At that moment, Dapeng vividly performed the persistence of a small person in society, which can be called "acting to seal the gods."

In addition, "Keep You Safe" continues to bring together many domestic first-line comedians. However, unlike the past, this time, Dapeng did not let these stars simply show their faces to enhance their attention, as in the past "diors man", but carefully designed to put each comedian in the most suitable role position for them, reflecting its ability to use people accurately as a director. For example, the constant use of golden sentences for the role of "sissy", the clever interpretation of Li Xueqin’s secular wisdom, the accurate handling of smooth and cowardly but essentially kind characters, and the interpretation of the image of the hypocritical bully boss, etc., make Dapeng’s films no longer rely solely on good popularity to make comedy stars simply "punch a card" in the movie like "Water Margin", but really go deep into the needs of the role and inspire these grounded comedy actors, such as. At present, the phenomenal popularity of TV series The Knockout is largely due to the sympathetic "human feeling" of a wicked person who plays Gao Qiqiang. Similarly, behind a good work, it not only reflects the actor’s strong role-building ability with a strong sense of hierarchy, but also lies in the extremely detailed foreshadowing of the character’s pre-history and the full design of the character’s motivation.

Third, the real emotional resonance of life

The above excellent "shape" of the plot and performance permeates the ingenious conception of the details in "Keep You Safe" and is all over the nuanced response to the narrative. However, compared with the skillful technology and rich experience in form, "God" is the core competitiveness of "Keep You Safe". Only when the director really "attentively" experiences the lines of the film and the emotions of the actors, completes the "empathy" between the director and the works first, and then fully exerts the inner tension of the film "vividly", can the audience and the works be helped to form a true and empty inner resonance.

A famous actor once summed up his acting experience and said that acting should not be performed, and emotions cannot be performed.

Comedy is the most difficult to shoot, because it is difficult to grasp the measure and depth of tears in laughter, because there must be recognized values rooted in the hearts of the audience behind this measure to support the theme. Dapeng, who has been honed for many years, in the comedy "Keep You Safe", shows a thorough understanding of the world’s coldness and ups and downs of life, and sincerely "flows into" the audience’s heart through comedy communication. Just as there was a video on the Internet that was widely circulated, the title was "There is no acting, but it’s just life". In "Keep You Safe", what supports Wei Ping’s efforts is his instinctive fatherly love for his beloved daughter, but when her daughter was scarred by campus bullying because of her own values, the belief supporting Wei Ping’s efforts collapsed. But the film didn’t stop there, but designed the daughter to comfort and encourage her father in turn, giving the adult great courage, which further sublimated the theme of emotional value in the film. This true interpretation of how ordinary people help each other and encourage them to live well is the most touching.

In addition, many metaphors in the film subtly echo the theme core of this warm realism. For example, when Wei Ping-an struggles whether to sacrifice himself again and stand up for a dead customer, the film presents this inner entanglement with spider pictures entangled in spider webs; Another example is the repeated appearance of the white horse image, which is actually like the moral sense of "superego" in the personality structure, realizing the inspiration of Wei Ping-an’s "id" and finally helping Wei Ping-an find back his persistence and courage of "self". It is precisely because of the great pressure caused by the violent invasion of public opinion in the internet age that this persistence is so precious. Even though Wei Ping-an is a "nobody" in the movie, his choice itself proves that he seems to be a "diaosi" and is actually a real "strong man".

Dapeng’s interpretation conveys that although the reality is cruel, he still chooses the kind "ordinary hero" realm, "Do what you think is right, whether it is worth it or not." "Do what you think is right." is also the core value that Dapeng wants to convey inside and outside the film. "Keep you safe" can invite many big-name comedians, especially many comedians from the bottom, which not only proves Dapeng’s sincere friendship, but also reflects his understanding of the ups and downs of life. "Keep You Safe" is like an "author’s film". In the film, the details of the plot such as opening a coke and the internal design of lines such as "Call Me Little Brother" echo the open-minded and optimistic experience that has passed away, that is, it is precisely because the director has a deep observation and understanding of life and loyalty that he can interpret this touching and vivid emotion and arouse the audience’s internal resonance.

The producer of "Keep You Safe" has been on the program "Please Advise the Director", in which her understanding of the film’s emotion is the same as the core theme of "Keep You Safe". For example, in the short film made by the director she supported in the program, she always said, "This film is the best film I have ever seen, and it made me firmly remember two lines: the fake can’t be proved, and it really doesn’t need to be proved. With these two sentences, this film will stand. " As written in Dialogue with Inner Fear — — "Emotion doesn’t need IQ, it is IQ itself." This film "Keep You Safe" produced by Chen Zhixi also continues this expression of true feelings. When it can express sincere feelings from the heart based on skillful and exquisite imaging technology in a limited time, it will surely win the hearts of the audience.

The reason why "Keep You Safe" stands out in the post-Spring Festival is precisely because it shows this kind of "both form and spirit": the seemingly unpretentious but skillful image language skills are the carrier of its "form", while the "spirit" of the film is reflected in the director’s sincere and thorough perception of life. Perhaps this is the reason for the success of "Keep You Safe": the most advanced comedy is the performance of real life.

Special fund support for national film industry

　　【PConline talk】 Since the popularity of smart phones, their endurance performance has become the main factor for everyone’s criticism. Although the current mobile phone has a large battery of three or four thousand mAh, it still cannot escape the situation of heavy users rushing every two days or even every day. At present, limited by the development of electrode materials/structures, the energy density of lithium batteries cannot be increased indefinitely. Therefore, charging has become an essential part of our daily life. So what is the knowledge of charging mobile phones? Today, the author talks to you about "how to charge correctly and safely."

Brief introduction of charging principle of mobile phone lithium battery

　　Charge first①In the constant current stage, the actual battery voltage is lower than the charging voltage (mostly 4.3v), and the battery voltage rises during the constant current charging process. When it rises to about 4.3v (the battery charge is about 85%), it enters.②Constant voltage mode, charging current gradually decreases, charging is about to be completed, and then enter.③Trickle charging mode, charging with pulse current, extending battery life.

　　Let’s start with a charging process diagram of mobile phone charging (lithium battery):

Battery charging curve

　　It doesn’t matter if you don’t understand the above one. In fact, in simple terms,The whole charging process of smart phone can be divided into three parts.：

　　①Constant current stage, when the actual battery voltage is lower than the charging voltage. The battery voltage (red solid line in the figure) gradually rises from a low value to a fixed value, but the current (blue solid line in the figure) remains unchanged. This is the constant current process of lithium battery charging.

　　②In the constant voltage stage, after the battery voltage reaches a fixed value, the current output to the battery gradually decreases, and the charging efficiency also begins to decrease. And this process is a constant pressure process.

　　③Trickle charging mode, finally, when it is close to full, enter the trickle charging mode and charge with pulse current until it is completely full, and the battery charging is completed.

Have you tried all these wrong charging methods?

　　1. Buy a new machine and charge it for 12 hours to "activate" the battery.

　　Many friends around me like to charge their new mobile phones for 12 hours, saying that this will activate the battery. In fact, the activation of lithium battery is not so troublesome. After long-term storage, lithium battery will indeed enter a "dormant" state, and its capacity is lower than normal. At this time, it only needs to be charged normally for 3~5 times (without deliberately charging/discharging) to activate the lithium battery and restore it to its normal capacity.

　　So you don’t need to drain the battery and charge it continuously for 12 hours when you buy a new machine.

　　2. Plug in the charger and play with your mobile phone while charging.

　　We often hear in the news that someone’s mobile phone explodes or gets an electric shock while charging. The final investigation results show that most of them are caused by shanzhai chargers, so if you need to buy a non-original charger, you must buy a product that has passed the national 3C certification, and the input/output parameters are correct, and the manufacturer information is available.

　　Simply put, when choosing a charger, you need to pay special attention to the following situations:

— — （1）.The input voltage is preferably a broadband voltage, that is, 100~220v/50~60Hz.In some areas, the charging head only has 110v input. If you take it back to China, you can burn the charger directly, or burn the mobile phone!

— —（2）.The output voltage is about 5v (4.9/5.1), and the larger the output current, the better (if it is too small, the charger often heats up at full load and the output is unstable), but if one end of the wire is a microUSB port, it will basically not exceed 3a, and the Type-C port may have more than 3 A.The amperage here only represents the allowable output current, not the real output current.

— —（3）.National 3C certification is a must.

— —（4）.Manufacturer information must be available.

— —（5）.The work of the cottage charger is rough (especially the beard insertion and the sealing edge of the shell) and the font is fuzzy, which must be distinguished.

— —（6）.Mobile phones that support fast charging are not recommended to use too thin wires for charging. VOOC flash charging can only use original wires, and QC fast charging wires must ensure the integrity of D+/D- lines (that is, connecting computers can identify devices).

　　In addition, we should not play while charging. After all, when charging, the battery and charging related circuits will emit a lot of heat. If the Soc of the mobile phone runs at high load, the body temperature will be too high. The mobile phone with too high temperature will also control the heat by reducing the performance and charging speed, which will lead to the slow charging experience.

　　3. Charge only when there is no electricity, and it will be full as soon as it is charged.

　　Don’t wait until the battery of your mobile phone is completely exhausted, and there is no need to fully charge the battery every time.Most of the current mobile phones are lithium batteries, and the emphasis is on "eating less and eating more meals". The life of lithium battery is measured by the charging cycle, not the charging times as everyone thinks. The charging cycle refers to the process that all the battery charges from full to empty, and then from empty to full. If there is a 2000 mA battery, you will be fully charged after every 200 mA, then you have to charge it 10 times to calculate a charging cycle (2000 mA =200mAh times 10 times).

　　The lithium battery that the mobile phone is now equipped with has no so-called memory effect. There is no need to worry about the impact of insufficient charging on battery life.Fill it if you want, and pull it out if you want.

　　4. When charging, the fever is obvious. Still wearing a mobile phone case.

　　Nowadays, almost everyone on a smart phone will give him a gorgeous "coat". I don’t know that lithium batteries will be hot when charging. These gorgeous "coats" will hinder the heat dissipation when charging the mobile phone, thus affecting the charging speed and even accidents.

　　If the user finds that his mobile phone is not obviously hot when charging, there is no need to take off the mobile phone case. If the mobile phone is hot when charging, he will take it off decisively.

Tip: How to charge quickly?

　　1. Shutdown charging/flight mode charging

　　　Many people know that the screen and processor are the most power-consuming places of mobile phones, but in fact, the RF module of mobile phones also consumes a lot of power, that is, even if you turn off the screen, if the mobile phone is still synchronizing data (for example, WeChat is still receiving messages), then your charging speed will not be fast.

　　So, when needed,urgentWhen charging, turning off the power of the mobile phone is the fastest charging method. In addition, we can also switch the mobile phone to flight mode, cut off the synchronization of data and improve the charging efficiency.

　　2. Make the phone cooler

　　In addition, too high/too low temperature will also affect the charging efficiency of lithium batteries. Apple said that the iPhone has the highest charging efficiency at room temperature of 22℃.

　　Android phones also use lithium-ion batteries or lithium-ion polymer batteries, so the appropriate charging room temperature should be close to iPhone. Therefore, avoiding too high or too low temperature during charging is also a way to improve the charging efficiency of mobile phones.

　　3. Avoid using computer USB port to charge.

　　When choosing a charger, many people will plug their mobile phones into the USB port of the computer conveniently, but the current output from the USB port of the computer is usually less than 1a(USB 2.0 500mA, 3.0 900mA). Therefore, it is recommended to use an independent power adapter, and the output current of the power adapter (charger) is suitable to be larger, so that the charger can output more current when the mobile phone has greater charging power demand, and it also avoids the unstable output caused by the long-term high-load operation of the charger (the one with small output current).

How to store the lithium battery of mobile phone?

　　1. Occasionally fully charge and discharge, and reserve a certain amount of electricity.

　　Although there is no memory effect in lithium batteries, there is no need for deep charging and discharging every time, lithium batteries, like other batteries, will have an "inert effect". If the chemicals in the batteries often do not participate in the reaction (that is, they are often not fully charged), they will also lose a certain capacity. Therefore, if the mobile phone is not used for a long time, it needs to be fully charged/discharged occasionally (once every 3 months or so), while lithium battery storage should avoid full charge/zero charge, and it is best to have about 40% power.

　　2. Avoid high temperature storage and physical impact.

　　Mobile phone lithium batteries that have not been used for a long time should be placed in a cool place to avoid electrostatic fire caused by being too dry, and should not be placed in a place that is too humid, because temperature and humidity will make lithium batteries self-discharge.
