　　[PConline evaluation] "Keeping pace with the times" is like the blood flowing in the body of a technology manufacturer. Without blood, you can’t survive; Without hematopoiesis, there is no vitality. And "keeping pace with the times" has different concrete appearances in different industries and different types of manufacturers. For example, in the notebook industry we are going to talk about next, "keeping pace with the times" means using the latest hardware and adopting a design language that fits the times and approaches consumers.

　　From the hardware point of view, the latest hardware is nothing more than Intel’s eight-generation (thin notebook)/nine-generation (game notebook) processors and NVIDIA’s MX (thin notebook) /RTX (game notebook) graphics cards. As a leader in the notebook industry, what kind of new hardware is connected in series and what kind of design is used to make Lenovo’s products stand out in the fierce competition in the market? This time,

　　Intimate design and accurate positioning of users

　　Just as black and white is an eternal classic, simplicity is a design that never falls behind. However, simplicity does not mean monotony, and how to distinguish simplicity from monotony, Lenovo Xiaoxin Air 15 2019 is realized by small corner LOGO embellishment.

　　The front of Lenovo Xiaoxin Air 15 2019 is treated with frosting and spraying technology. On the whole, it looks strong in metal texture, and it is dry and delicate in practice.

　　On the front of Nuoda, except Lenovo Logo in the upper left corner, the notebook has no other gaudy logo, which is concise and clear, not only conforms to the design pursuit of simplicity and fashion of young people at present, but also shows the neatness and competence of business elites when taking it on business trips.

　　When it comes to the use of business elites, Lenovo Xiaoxin Air 15 2019 is equipped with many practical interfaces. Among them, from the outside to the inside, USB 3.1 interface x 2, SD card reader and small hole with "one-button recovery" function are arranged on the right side. The external USB 3.1 interface can charge mobile phones, tablets and other devices even if the computer is turned off. The notebook is cleverly transformed into a large charging treasure, and there is no need to carry multiple charging treasures on business trips, which is easy and enjoyable; The "one-button recovery" function converted from the ThinkPad blue key can also help users get out of trouble easily when they encounter intractable problems such as system crash/computer blue screen.

　　As for the left side, the power interface, HDMI display interface, USB Type-C interface and 3.5mm 2-in-1 audio interface are listed in turn. With the addition of USB Type-C interface, the diversified interface support of the computer is realized. No matter what type of data cable the mobile phone uses, there is always an interface suitable for you.

　　At the back of the rotating shaft and the bottom of the notebook, a large fence corresponds to the cooling fan of the notebook, and the heat generated when the notebook runs large software also has sufficient cooling space.

　　In addition, different from the traditional four-corner foot pads, Lenovo Xiaoxin Air 15 2019 uses 2+1 rubber foot pads at the bottom, with long and thick rubber foot pads. With the first two small foot pads, the notebook can be used stably in more scenes.

　　Thanks to the flexibility of the rotating shaft, the opening and closing angle of Lenovo Xiaoxin Air 15 2019 model can reach 180. It is also very convenient to play drama on the sofa/bed in leisure time and discuss ideas with others at work.

　　The narrow bezel design that keeps pace with the times generally stays at a width of 7.5mm in the market, while Lenovo Xiaoxin Air 15 2019 has achieved a width of 4.25mm, which makes the notebook screen account for as much as 85.3%. The 15.6-inch notebook looks only the size of the traditional 14-inch notebook. When users are working, their horizons are wider and their mood is naturally brighter, and they can also feel greater vision when watching movies.

　　Due to the integration of the camera and microphone required for video, the forehead of Lenovo Xiaoxin Air 15 2019 is not as narrow as the borders on both sides, but it is still much narrower than the ordinary models on the market. On this narrow forehead, Lenovo skillfully added a physical peep-proof switch to the camera, turned it off to the left and turned it on to the right. In an era when privacy is increasingly valued, sometimes an excellent design language is a small and intimate design that meets the needs of the times.

　　Now that we talk about privacy protection, fingerprint recognition is indispensable for a light notebook that keeps pace with the times. In the lower right corner of the keyboard of Lenovo Xiaoxin Air 15 2019, the fingerprint recognition function is added to Lenovo Xiaoxin Air 15 2019. This pressed fingerprint key can be used as a power-on key, and it can be unlocked to enter the system when it is dormant, thus avoiding the embarrassment of inputting passwords in front of many people and effectively protecting personal privacy.

　　Maybe you will ask, with this button, what is the function of the power button in the upper right corner? Just as the "one-button recovery" function exists, a backup scheme is also needed for the safety of business use. The existence of the power key is not only the first entrance when fingerprint identification is not set, but also the second entrance when fingerprint identification fails.

　　In order to get a better feel, many users like an external mechanical keyboard. Going on a business trip means saying goodbye to the mechanical keyboard, but using Lenovo Xiaoxin Air 15 2019 does not mean saying goodbye to a good feel.

　　Lenovo Xiaoxin Air 15 2019 keyboard adopts an isolated chocolate keyboard, and each key exists independently, with a distance of 19.05mm, which is not easy to touch by mistake; The key stroke is 1.3mm, and the quick tapping response is quick; Coupled with the matte paint on the surface of the keycap, although the feel is not as good as that of the mechanical keyboard, it is definitely not bad for business trips.

　　In addition, it is not difficult to use the backlight at night by calling up the backlight through FN+ space bar. And the digital keyboard area that makes full use of space will greatly improve the office efficiency for friends who have to deal with numbers every day.

　　In the touchpad part, Lenovo Xiaoxin Air 15 2019 adopts an integrated glass touchpad solution. The area looks small, but it is very sensitive and smooth in actual operation. It can complete accurate operation only by clicking and gesturing, and it is not a big problem without a mouse in daily office.

　　Surrounding dolby pro logic with 15.6-inch ultra-narrow bezel and high color gamut full HD IPS full screen not only provides users with excellent audio and video experience visually but also audibly.

　　In terms of thickness and weight, Lenovo Xiaoxin Air 15 2019 is made of aluminum alloy metal, which provides sufficient strength guarantee for the fuselage, and also makes the whole notebook lighter. The thinnest part is 16.9mm, and the 15.6-inch fuselage with power adapter is only 2.3kg (1.76kg for the fuselage), so it is relatively light to carry on business trips.

　　Excellent configuration to enhance user experience On the screen side, Xiaoxin Air15 2019 adopts the popular "high color gamut IPS screen", which has a high color gamut coverage of 72%NTSC, and the screen resolution is 1920×1080. The surface layer is treated with anti-glare atomization, and with the high brightness of 300 nits, it also has a good impression under strong light.

　　On the processor side, Lenovo Xiaoxin Air 15 2019 is an eight-generation Core i7-8565U equipped with Intel’s latest Whiskey Lake architecture. This processor has been enhanced, and its performance is at least 10% higher than that of the i7-8550U introduced earlier, with a main frequency of 1.8GHz, a turbo frequency of 4.6GHz, 4 cores and 8 threads, a third-level cache of 8 MB, and a TDP of 15W.

　　With a stronger eight-generation Core i7-8565U, Lenovo Xiaoxin Air 15 2019 also enables multi-mode support. Through FN+Q, users can switch between beast, mute and balanced modes at will.

　　When the external power supply is inconvenient for business trip, use the "silent" mode with longer battery life; Leisure and entertainment want to play games such as League of Legends to start the "beast"; Multi-mode selection also makes it better adapt to more usage scenarios.

Silent mode

Beast mode

　　Then, under different modes, what is the performance difference of Lenovo Xiaoxin Air 15 2019? We tested its lowest performance "silent" mode and the strongest performance "beast" mode through CINEBENCH R15. The results are shown in the figure, and the final results of the "silent" mode are: multi-core 542cb and single-core 160cb；; Final results of "Beast" mode: multi-core 694cb, single-core 171cb.

　　Judging from the score, the silent mode is quite different from the Beast mode, but don’t underestimate the performance of the silent mode, which is only a little lower than i7-8550U (single core 166cb, multi-core 561cb), which also means that in the silent mode, any browser can be opened more, office software can be used, or PS retouching, video editing and simple rendering can be done.

　　As for the "Beast" mode, the single-core performance basically exceeds that of the previous generation i7-7700HQ standard voltage. In other words, this processor has more than enough computing power to deal with some mainstream online games.

　　Since there is no problem with the computing power of the processor, the only other factor that may hinder the notebook from playing is the core temperature. We use AIDA for this part? 64 Carry out CPU copying test on Lenovo Xiaoxin Air 15 2019. Under the condition of 100% high load, we can see that the core temperature of i7-8565U fluctuates regularly between 70℃ and 90℃, and the whole process processor runs stably without sudden frequency drop. It is not easy to perform stably at high temperature. This achievement is not only due to the low power consumption of Intel processor, but also thanks to the design skill of Lenovo’s double fans, double copper pipes and die cooling of the whole machine.

　　During the copying process, we tested Lenovo Xiaoxin Air 15 2019 with infrared thermometer. Under the condition of room temperature of 26.1℃, the high temperature area of the machine is mainly concentrated in the heat dissipation port at the rotating shaft, with the highest temperature of 47.3℃. Only by touching that position with your hands can you feel the temperature.

　　As for the graphics card, NVIDIA MX250 has a core frequency of 1519MHz and a memory frequency of 1752MHz. It is full of blood without castration, and its performance is improved by 5% ~ 10% compared with the "full blood version" MX150, which can meet the needs of ordinary 3D online games and barely getting started eating chicken. In addition, the editing speed of general pictures and videos such as Photoshop, Illustrator, Lightroom and Premiere will be faster.

　　In the hard disk part, Lenovo Xiaoxin Air 15 2019 has a built-in 1T PCIe SSD. In the test of CrystalDiskMark, the sequential reading and writing speed of 1G file is as high as 3453MB/s and 2107MB/s, and the random reading and writing performance of 4K is 37.35MB/s and 77.78mb/s. To be honest, it is quite unexpected that the sequential reading and writing can reach such a high speed. This side reflects that Lenovo uses the same amount of materials in invisible places, and uses high-standard hardware at any cost, in exchange for a smooth user experience with 5 seconds of boot and rapid software response. In terms of product scalability, according to the official product introduction, Xiaoxin Air15 2019′ s memory supports a maximum of 20G dual-channel memory expansion. The SSD also supports dual SSDs, with extra M.2242 extension bits reserved, and supports PCIe bus and NVMe protocol as well as the main hard disk bits. As a thin notebook with a thickness of only 16.9mm, its storage scalability is still worthy of recognition.

　　The battery life-related part is a highlight of Air15 2019. Compared with the previous generation of 45Wh and the current situation that the products of the same level are mostly hovering at 50-60Wh, this year’s Air15 2019 battery has jumped to a super-large capacity of 70Wh, which is a ride in the same level of light and thin books. The official announcement has the longest battery life of 19 hours. Of course, this is the theoretical time. In fact, it is closer to the scene used by users. We recommend using PC Mark8′ s Work mode battery life test. Due to the compatibility problem with the language pack of PC Mark8, it is temporarily impossible to carry out the battery life simulation test on the test machine on hand. According to the results released by netizens at present, the longest working mode can reach about 7-8 hours. This has obvious advantages over the common score of about 5 hours.

　　In addition to the large battery, Air15 2019 also supports ultra-fast charging technology, claiming that it can be used for 4 hours after charging for 1 quarter of an hour, and it can use the fragmented time to quickly "return blood" to the computer. However, the description of 65W high-power adapter reminds me of Z6 Pro’s "27W fast charging adapter" some time ago, which is funny manually.

　　Summary:

　　Even if it is implemented in notebooks, the performance of "keeping pace with the times" is different because of different product segments. Lenovo Xiaoxin Air 15 2019, based on the common elements such as large screen, all-metal, thinness and uniqueness, also strengthened the two outstanding advantages of screen quality and battery capacity, and explained to you the configuration and design language that a large-size business thinness should have. Its version of i5/8G/1T SSD/MX250 is priced at only 5499 yuan, which is still very competitive in a light and thin book of 5000 yuan. .

　　According to the latest data released by the Ministry of Commerce of China, the actual amount of foreign capital used in China in the first month of the year was 127.69 billion yuan, up by 14.5% year-on-year. The scale has steadily increased and the structure has been continuously optimized, which shows that China is still a hot spot for foreign investment. International organizations and foreign-funded enterprises in China have expressed their optimism about China’s economic development prospects, believing that China’s economy will make generate more dynamic and bring more market opportunities and development dividends to the world.

　　In January this year, Standard Chartered Bank was granted permission to set up a wholly foreign-owned securities company in China, becoming the third wholly foreign-owned securities company approved after JPMorgan Chase Securities and Goldman Sachs Gaohua Securities. "China unswervingly promotes high-quality development, deepens reform and opening up, and especially continues to promote financial opening up on a higher level, which provides huge development opportunities for foreign financial institutions." Zhang Xiaolei, head of Standard Chartered Bank, said.

　　Schroeder Fund was recently approved to set up a wholly foreign-owned Public Offering of Fund management company in China, becoming the fifth wholly foreign-owned Public Offering of Fund company in China. Guo Wei, the person in charge of Schroeder’s investment, said: "This cannot be separated from the support of a series of favorable policies of the China government to expand the opening up of the financial industry. We will actively promote the preparatory work. "

　　According to the latest annual questionnaire survey of the German Chamber of Commerce in China, half of the enterprises surveyed expressed their willingness to continue to invest in the China market, and nearly 80% of the enterprises surveyed held a positive attitude towards the medium and long-term prospects of the China market, hoping to gain opportunities in the tide of scientific and technological innovation in China.

　　"From the extensive growth of scale and speed to the intensive growth of quality and efficiency, and from the drive of factor investment to the drive of innovation, the continuous reform in China will help achieve high-quality development." Kang Zhongzhi, an economist of the International Monetary Fund, said in an interview with this reporter that in recent years, China’s capital market has been more deeply integrated into the global financial market system, and the negative list of foreign investment access has been reduced for several consecutive years. At the same time, China has given full play to the decisive role of the market in resource allocation, continuously strengthened the protection of intellectual property rights and deepened the reform of the household registration system, which has enhanced the vitality of market competition and the mobility of labor. China has achieved tangible results in promoting structural reforms on the supply side, and the economy will further achieve high-quality development in the future.

　　On January 8th, China resumed China citizens’ outbound tourism in an orderly manner, and gradually resumed the entry and exit of passengers at land and waterway ports. A number of foreign countries in the Chinese Chamber of Commerce recently said that this move has brought obvious benefits to the regional economy and global trade. The British Chamber of Commerce in China issued a statement saying that as the epidemic prevention and control entered a new stage, the optimism of enterprises continued to rise, and "China has once again become a priority investment destination".

　　The report released by the African Development Bank in January believed that after China optimized and adjusted its epidemic prevention policy, Asia, as an important export market in Africa, would achieve steady growth, thus expanding the development space of Africa.

　　Park Zhi-shui, chief economist of the Asian Development Bank, said that China’s economic recovery will greatly promote the Asian economy. The sharp rebound in consumer demand in China not only boosted the exports of trading partners to China, but also benefited all value chains connected with China.

　　Goldman Sachs Group recently released a report saying that the accelerated recovery of China’s economy will boost global economic growth. "With the improvement of global financial conditions and the increase of international trade, the spillover effect of China’s economic growth will be even greater".

　　[Global Network Reporter Zhang Xiaoya] According to Agence France-Presse, the Brazilian government said on March 29th that China and Brazil had reached an agreement to trade in local currency instead of using the US dollar as an intermediate currency.

　　Agence France-Presse said that this agreement will enable China and Brazil, the largest economy in Latin America, to conduct large-scale trade and financial transactions directly, and exchange RMB for the real, and vice versa, instead of using the US dollar as an intermediate currency. The report said that the agreement was announced after the China-Pakistan high-level business forum held in Beijing. In January this year, the two sides reached a preliminary agreement on this.

　　"This is expected to reduce costs … … Promote bilateral trade and investment facilitation. " The Brazilian Export Investment Promotion Agency said in a statement.

　　Agence France-Presse said that China is Brazil’s largest trading partner, with bilateral trade reaching a record $150.5 billion last year.

　　Bloomberg reported on March 25th that before Brazilian President Lula’s visit to China, hundreds of representatives of Brazilian agricultural enterprises "flocked to Beijing" this week, seeking to increase export cooperation with China and attract investment. Reuters also said that the delegation visiting China is huge, including cabinet ministers, governors, parliamentarians and 240 business leaders. Most of Brazil’s beef, soybeans and wood pulp are exported to China. Brazilian Foreign Ministry officials said that Brazil hopes to expand its trade with China beyond the export of iron ore, soybeans, soybean oil and meat, and is ready to sign agreements on technology, innovation and sustainable development.

　　According to the news published on the website of the People’s Bank of China in February, recently, the People’s Bank of China and the Central Bank of Brazil signed a memorandum of cooperation on establishing RMB clearing arrangements in Brazil. The establishment of RMB clearing arrangements in Brazil will be beneficial to enterprises and financial institutions in China and Pakistan to use RMB for cross-border transactions, and further promote the facilitation of bilateral trade and investment.

As a means of transportation that relies on electric energy, it is essential to charge electric vehicles. However, different car owners have different ideas about the habit of charging electric vehicles. Some of them charge only when the power is running out, and some people charge frequently and charge every day. So, can electric vehicles be charged every day? The little expert made it clear once today and really learned it after reading it.

As for the way of "charging every day", it can’t be said that it is absolutely correct or absolutely wrong. After all, if the battery life of an electric car is only forty or fifty kilometers and you travel twenty or thirty kilometers every day, you have to charge it every day. Whether you can charge it every day depends on whether the advantages outweigh the disadvantages or the disadvantages outweigh the advantages. Let’s take a detailed look at the advantages and disadvantages of "charging every day" of an electric car.

Regarding the habit of "charging every day", what are the advantages of it compared with the need to use clean electricity to recharge? According to the expert’s summary, there are two simple and clear ones.

The first is to reduce the battery vulcanization reaction and slow down the battery aging speed:

What kind of battery is the fastest aging, that is, the battery with faster vulcanization speed, which leads to battery vulcanization, and the most important point is power loss. As long as the battery is discharged and not replenished in time, the sulfuric acid concentration of the battery is thin, and sulfide crystals will form, which will lead to battery capacity reduction and battery aging.

If the battery is charged every day, it can be replenished in time after discharge, and the concentration of electrolyte in the battery gradually increases, returning to the concentration before discharge, which can prevent the battery from vulcanizing and slow down the aging speed of the battery.

Secondly, there is no need to worry about the power failure halfway, and there is no need to take emergency treatment methods that damage the battery:

If the electric car is charged every day, there will naturally be no trouble in the middle of the road. As long as there is no electricity in the middle of the road, the emergency switch such as ACS provided by the manufacturer will not be used by the owner, and there is no need to worry about damaging the battery.

As for the ACS switch, it can still release electric energy when the electric vehicle shows insufficient power, but once it is turned on, it will release all the protection voltage of the battery, which is very harmful to the battery. If it can be used, try not to use it.

Talking about the advantages of charging every day, but since discussing this way, there must be advantages and disadvantages, otherwise there is no need to discuss it. Then, what are its disadvantages, you can also sum up two.

The first is the waste of cycle charge and discharge times of the battery:

No matter what kind of battery, as long as the cycle charge and discharge times are used up, the battery will be scrapped, and charging every day with enough electricity will inevitably lead to the waste of times, especially lead-acid batteries, which must be avoided. It only has about 300 charge and discharge times. If it is used once every three days, it can be used for three years. If it is charged every day, the usable time of the battery will inevitably be shortened.

Secondly, it is easy to accelerate the water loss rate of the battery;

There are two important structures in the battery, the first is the lead plate, and the second is the electrolyte. If the battery is charged every day, the battery temperature will inevitably rise, which will evaporate the electrolyte. If a battery is charged and charged infrequently every day, the water loss rates of the two will be obviously different. When the battery electrolyte is insufficient, the battery performance will be affected and its life will be shortened.

Through the above introduction, we can get an answer. It is not recommended to "charge every day" for electric vehicles. Of course, if the power of electric vehicles is not enough to maintain the battery life for 2 days, it can be "charged every day". Compared with daily charging, it is not perfect. The following experts share the correct charging method, which is conducive to improving battery life.

1. The power of the electric car is enough for more than 2 days. Don’t charge it every day. Recharge it when the power is about 20%.

2, equipped with a lithium battery, because the number of charge and discharge is more than 1000 times, you can charge according to your habits;

3. Charge electric vehicles to avoid sub-zero environment;

4. Every time the electric car is charged, the charger will continue to charge after it turns green to complete the floating charge;

There is no need to choose between the charging habits of electric vehicles. Whether electric vehicles should be charged every day depends on the battery capacity and battery type. Can electric vehicles be charged every day? Through the analysis, it can be seen that lithium batteries are completely ok, while lead-acid batteries have advantages and disadvantages. It is necessary to master the correct charging method according to the situation of electric vehicles and improve the battery durability. What do you think of this? Welcome to comment and exchange.

Li Qinfeng, Director of Domain Name Business Department of Domain Name Registration Management Center of Government Affairs and Public Welfare Organizations

With the extensive and in-depth application of information technology, especially the continuous development of e-government, the website of party and government organs has become increasingly prominent. It has become an important window to publicize the party’s line, principles and policies and open government information, and an important platform for party and government organs at all levels to perform social management and public service functions, do things for the people, understand social conditions and public opinion, and accept supervision by the masses. The Fourth Plenary Session of the 18th CPC Central Committee put forward that "network behavior should be regulated according to law", which requires us to institutionalize and standardize the management of online names of party and government organs according to law, so as to ensure that the websites of party and government organs are "be worthy of the name, standardized names, safe operation and healthy development", thus ensuring the safety of websites of party and government organs and institutions.

First, the connotation of website security of party and government organs and institutions

General Secretary of the Supreme Leader pointed out that there is no national security without network security, and it is necessary to strengthen the management of new technologies and applications in the network to ensure that the Internet can be managed and controlled. Internet is a double-edged sword, well used, it is the treasure house of Alibaba; It doesn’t work well. It’s Pandora’s box. The website security of party and government organs and institutions includes three aspects: identity security, integrity security and information security.

One is identity security. In the real world, party and government organs and institutions have their own office space, which can only be listed, publicized and provided with services for the public after being examined and approved by the establishment departments at all levels in China, so its identity is well known to the public and is safe and reliable. However, in the virtual space of the Internet, in recent years, criminals posing as party and government organs and institutions have frequently set up fake websites, which has had a bad influence on the authoritative image of party and government organs and institutions and also caused losses to the public. Therefore, the identity security of party and government organs and institutions on the Internet needs to be guaranteed, so that the public can clearly identify them and will not be deceived by fake websites.

The second is integrity and safety. With the development of the Internet, the public can obtain government information and communicate with the government online in real time. The government can also contact the public synchronously, instantly, trans-regionally and trans-temporally through the Internet, and feedback the public’s demands for the government at the first time, thus effectively conserving, maintaining and cultivating the people’s trust in the government. However, due to various reasons, a large number of news in the name of the government have been published and reprinted on the Internet, and the public can’t tell whether these news are true or false. Some rumors confuse the public and even cause group incidents, which is not only detrimental to the long-term stability of society, but also directly damages the integrity and authority of the government.

The third is information security. At present, the websites of party and government organs and institutions have become an important platform for policy release and interaction between the government and the people, and at the same time, they have also become the carrier of public personal information because of the public’s online business. The Internet is logically divided into three layers. The first layer is the basic layer, including bandwidth, IDC computer room and mobile interconnected base stations. The second layer is the basic resource layer, including domain name, IP and so on; The third layer is the application layer, including mail, website, application system and so on. Among them, the second layer represented by domain name is the key to information security risks. If the Internet is likened to a highway, the second floor is equivalent to signs and cameras on the highway. If the highway of China’s Internet is guided by English signs and monitored by foreign cameras, then security can certainly not be guaranteed. Therefore, if Chinese government websites use commercial domain names, each parsing data will be reflected in the root server of this domain name, which will be mastered by foreign countries. Once the website has security risks, the public’s personal information will not be guaranteed, which directly threatens China’s network information security.

In a word, it is very important for party and government organs and institutions to ensure the safety of their websites. This requires that the identity of the websites of party and government organs and institutions can be confirmed, the voice can be distinguished, and the information can be guaranteed.

Second, how to ensure the website security of party and government organs and institutions

Online name management refers to the four-in-one comprehensive management with the use of online names and online identity identification of party and government organs and institutions as the core and domain name registration, website audit, website labeling and annual report as the main contents. Through the monitoring, retrieval, identification and protection of the online identity of institutions, it is widely used in various platforms such as Weibo, WeChat and browser, and finally makes the online identity clearer, the network environment clearer and the online business more secure.

(1) Domain name registration

According to the Interim Measures for the Administration of Online Names of Party and Government Organs, Institutions and Social Organizations (hereinafter referred to as Document No.6) jointly issued by the Central Committee and the Ministry of Industry and Information Technology, party and government organs and institutions must register and use standardized Chinese domain names for ".government affairs" or ".public welfare". These two Chinese domain names are technically unique, highly recognizable in form and strictly managed by the organization’s establishment department, which makes them qualified as "online identity cards" for organizations, and also makes Chinese domain names the premise and core of online name management.

(2) Website audit and website labeling

In May 2014, the Central Network Information Office issued the Notice on Strengthening the Website Safety Management of Party and Government Organs (hereinafter referred to as Circular No.1), which clearly required the organization department to be responsible for the website start-up audit and qualification review of party and government organs, and to design and formulate the usage norms of website logos of party and government organs.

Website labeling refers to placing a unified website logo in a prominent position at the bottom of the website after the websites of party and government organs and institutions are approved by the organization department. Clicking this logo will display the basic information of the company and the online name, etc., so as to facilitate the public to distinguish the authenticity of the website.

(3) Annual report

According to Circular No.6 and the Notice on Doing a Good Job in Auditing, Qualification Review and Website Logo Management of Party and Government Organs’ Websites (hereinafter referred to as Circular No.69) jointly issued by the Central Editorial Office and the Central Network Information Office, online names and website logos are subject to a regular reporting system, and website owners should regularly report online changes in their qualifications, the use of online names and website logos to the organization establishment department.

Third, the significance and necessity of online name management.

(1) Why is the organization department responsible for the management of online names?

The organization establishment department holds the most accurate information of organization identity and name, and is managed by the organization establishment department, which can effectively ensure the "be worthy of the name and standardized name" of party and government organs and institutions on the Internet. Therefore, as early as 2008, the Ministry of Industry and Information Technology clearly stipulated that Chinese domain names for government affairs and public welfare should be managed by the organization department. In 2014, in the No.1 document issued by the Central Network Information Office, it was further stipulated that the organization preparation department was responsible for the audit and qualification review of the website of the party and government organs, and designed and formulated the usage norms of the website logo of the party and government organs.

(2) Why should we register and use standardized Chinese domain names?

Chinese domain names for government affairs and public welfare conform to the language and cultural habits of Chinese people, and can clearly reflect the name and functions of institutions, similar to the "online ID card" of institutions. For example, the Chinese domain name compiled by the central government is "Central Compilation. Government Affairs". Compared with its English domain name "scopsr.gov.cn", the Chinese domain name is clear at a glance, which not only embodies the authoritative identity of the organization, but also facilitates public recognition and memory, and is the basic guarantee for netizens to surf the Internet safely and do things with confidence.

Fourth, the significance of establishing an online ID card authentication and protection application system with Chinese domain names as the core.

The first is to maintain authority. It is an important means to maintain their authoritative status in cyberspace to put on "anti-counterfeiting clothes" for institutions by standardizing online names and hanging website logos. The second is to make it safer to do things online. Marking the identity information of the organization on the Internet makes it easy for netizens to distinguish the true and false websites of the organization, which can improve the efficiency and facilitate the work on the Internet. The third is to ensure national information security. Party and government organs and institutions are the core political resources in China, and their information security on the Internet is particularly important. Strengthening the authentication and protection of its online identity can effectively guarantee the security of the country’s core information. The fourth is to make the organization management more scientific. Through website logo management, we can fully understand the online performance of institutions and provide scientific reference for the performance evaluation and management of institutions.

We maintain the seriousness and authority of the websites of party and government organs and institutions, protect the safety of the websites of party and government organs and institutions, and establish a green channel for the public to visit the websites of government departments and public welfare institutions quickly and accurately, so as to promote the popularization of Internet application and the development of government affairs openness and e-government in China.

Net exposure LAY holding hands

Netizen broke the news screenshot

Fans posted the original picture.

　 　 Today (September 5th), some netizens broke the news that LAY, a popular "little fresh meat", was in love with Diamond, the winner of the third season of The Voice of China, which triggered a hot discussion on the Internet. Subsequently, the reporter called the brokers of both sides of the incident, and both sides gave a denial reply. LAY’s agent responded: "(They) are really not in love", while Diamond laughed and said: "Where is this?" But then, some fans came forward to blame the idol, pointing out that the woman posted by the reporter was not Diamond, and uploaded the original picture to jokingly refute: "Is this our mother-in-law?"

??

　 　 A netizen named "Star Eight Gong" uploaded a group of photos suspected of LAY’s shopping in Weibo, and wrote: "LAY’s love affair was exposed. Some netizens witnessed LAY shopping with a mysterious woman, and it was very sweet to hug her waist and hold hands. It was verified that the woman was Diamond, the champion of "Good Voice of China" in the last season. " Suddenly triggered a hot discussion on the Internet, and netizens shouted unbelievable.

　 　 In this group of pictures, a man suspected of LAY is traveling in casual clothes, talking and laughing with a woman, and holding hands in public without any cover. However, because the photos were not clearly taken, the authenticity of the news was in doubt.

　 　 LAY, as the only mainland member of EXO, is very popular on the other side. Earlier, he was exposed to a secret love affair with Diamond, the champion of Good Voice 3. The whistleblower uploaded several photos of LAY holding hands and shopping with women, but most of them covered up the woman’s appearance, and then fans restored the original photos, pointing to the whistleblower as "malicious rumor". At present, Weibo, who broke the news, has been deleted, and fans have also shouted for LAY’s confidence, asking idols to concentrate on their work and not be influenced by rumors.

　 　 In this regard, the reporter immediately called LAY and Diamond’s agents, and both sides immediately denied it. LAY said it needed to respond to this rumor, and repeatedly stressed that the two were "really, really not in love". LAY’s agent added: "They are not friends. Diamond was a fan of LAY before, but they didn’t know each other."

　 　 After hearing the news, MISS ZHOU, the agent of Diamond, said with a smile: "Where is this?" And told reporters that there are many Korean artists. "Who said that if Korea comes back, it will have to be in love?"

　 　 Are the two friends? MISS ZHOU said that it was not long before he took over Diamond, and it was not clear.

　 　 People who go to the cinema to watch movies have more or less encountered such a situation and got a puzzling handwritten ticket; Obviously watching movie a, but the name of movie b is written on the ticket; The unit organized a group movie but didn’t get the movie ticket, so you can sit casually in it, anyway, it won’t delay you from watching the movie … … In fact, these are all manifestations of "stealing the box office".

　 　 In this regard, the Film Bureau of the State Administration of Press, Publication, Radio, Film and Television issued the Notice on Strengthening the Management of the Film Market and Regulating the Use of the Movie Ticketing System (hereinafter referred to as the Notice) on January 20, proposing to strictly improve the market access system for cinema ticketing software products. According to industry analysts, this move is the biggest "heavy punch" for the film bureau to purify the film market in the past decade.

Industry chaos：More than 5 billion box offices a year are "stolen"

　 　 In 2013, the national box office reached 21.769 billion yuan, compared with less than 1 billion yuan before the film industrialization reform in 2003. The development speed of China film market is amazing. However, in recent years, the situation of movie box office evasion and concealment has intensified. In April 2013, some netizens exposed the case of "stealing the box office" in a cinema in Sichuan. "I see, the staff of the cinema gave me a good ticket. Is this stealing the box office? "

　 　 There are many ways to steal the box office, which can be roughly divided into handwritten tickets, Zhang Guanli Dai tickets, group tickets, combined fares, changing system data, and dual systems (one system for bookkeeping and one system for reimbursement).

　 　 In view of the total box office in 2013, Wang Changtian, president of Light Film, bluntly said that at least 5 billion yuan of box office was stolen, and the real box office could at least exceed 26 billion yuan. According to the proportion of 40% of the total box office allocated to the production company, the producers have at least lost more than 2 billion yuan. According to the production cost estimate, the money is enough to shoot 12 films, 40 films and 60 films … …

　 　 On January 20th, the Film Bureau issued the Notice, relying on the Technical Requirements and Measurement Methods of Cinema Ticketing Management System (hereinafter referred to as the "13 Specifications"), and put forward a number of requirements, such as strictly improving the market access system of cinema ticketing software products, effectively strengthening the market application management of ticketing software products, strictly regulating cinema operation behavior, vigorously strengthening industry supervision, and intensifying the crackdown on illegal activities.

　 　 An industry insider who did not want to be named said that this move is tantamount to "playing the tiger in the film circle" and severely cracking down on those phenomena that leak and report the box office and disrupt the market. Its influence and meaning are significant and far-reaching.

Interpretation of the New Deal: How to check? Check the ticketing software and system one by one.

　 　 It is understood that all cinemas that join the cinema line for commercial operation in China must install a computer ticketing system. In order to regulate the use of this system, the former State Administration of Radio, Film and Television issued the "Technical Specification for Computer Ticket Management System Software in Cinema" in 2005. The "13 Specification" issued this time is the first major adjustment and revision of the 2005 Technical Specification.

　 　 1. Each ticketing software is "registered". The Notice emphasizes that the filing software must be consistent with the actual sales software. If the modules and functions required by the specifications are changed and upgraded, they need to be re-filed. This means that the characteristics of each ticketing software will be "registered", and the behavior of software vendors tampering with the program at will will no longer be allowed.

　 　 2. Spot check the cinema ticketing system from time to time. The "Notice" emphasizes that the film authorities at the location of the cinema are responsible for the acceptance of the cinema ticketing software after installation and the spot check during use. In addition, when cinemas use the cinema ticketing system to sell movie tickets, they need to submit box office data to the National Film Ticketing Integrated Information System within the specified time. Any information change is regarded as a serious business violation.

　 　 3. Movie tickets must be clearly marked. The cinema must exchange all kinds of movie cards, coupons, two-dimensional codes, online ticketing vouchers and other viewing credentials held by the audience for computer tickets through the computer ticketing system approved by the cinema. The fare printed on the computer ticket must be the same as the ticket actually paid by the audience. The film title printed on the computer ticket must be consistent with the film actually watched by the audience. It is strictly forbidden to sell or use movie tickets without clear film titles.

How to punish? Stop the film lightly, or disqualify it severely.

　 　 At the same time, the new regulations strengthen the punishment for violations. For general violations, in addition to the contractual stakeholders’ investigation of the breaching party’s liability for breach of contract according to the contract, depending on the degree of violations, warning, notification within the industry, media exposure, suspension of film supply, cancellation of various financial support and reward qualifications, cancellation of the qualification to participate in the evaluation of star-rated cinemas, and delisting of star-rated cinemas are taken. For serious violations of relevant national laws and regulations, the cinema’s "Film Projection Business License" shall be suspended or revoked.

Interpretation in the circle: "flies and tigers should fight together"

　 　 "Stealing the box office is a commercial fraud in a sense and a criminal act." In the view of Wang Changtian, president of Light Film, "(the introduction of the New Deal) will make the whole film industry enter a benign, orderly, fair competition and benefit-sharing mechanism. Let everyone’s labor achievements be respected, and let creation, intellectual achievements and intellectual property rights be protected. "

　 　 Wu Hehu, deputy general manager of Times Jindian Cinema, bluntly said that cracking down on box office evasion, regardless of tigers and flies, should be fought together. "Flies should also be severely punished, and some illegal theaters should not feel that even if they catch the problem, they will be punished less and earn more." He suggested that the cinema manager should be blacklisted and removed from the industry for cinemas that deliberately evade the box office.

　 　 Cao Yong, the head of Beijing Huaxing UME Cinema, said, "The introduction of these policies by the state is very good and timely, and great efforts should be made to implement them. Once found, the theater will be disqualified from commercial screening. It is not worth the loss to steal 100,000 yuan from the box office, so they dare not do so. "

The value-added tax invoice data with a wide penetration is a window to observe the production and operation of market players. According to the data released by State Taxation Administration of The People’s Republic of China on May 28th, in April this year, the sales revenue of national enterprises increased by 12.9% on average for two years, which continued a steady and positive trend.

On the whole, in April this year, the sales revenue of Chinese enterprises continued to grow steadily, the industrial economy continued to recover, consumption and investment steadily improved, and the recovery growth trend of the national economy continued to strengthen.

Zhao Lianwei, deputy director of the Revenue Planning and Accounting Department of State Taxation Administration of The People’s Republic of China, said: "The VAT invoice data shows that in April, the sales revenue of national enterprises increased by 24.6% year-on-year, 27.5% over the same period of 2019, and the average growth rate in two years was 12.9%, continuing the steady and good trend since the second half of last year."

In terms of industrial enterprises, the sales revenue of industrial enterprises increased by an average of 10.1% in two years, reflecting the steady recovery of the industrial economy. Zhao Lianwei said: "Among the 41 major industries, 38 industries have achieved positive growth on average in two years, and 16 industries have achieved an average growth rate of more than 10% in two years."

In the wholesale and retail industry, the sales revenue of the wholesale and retail industry increased by 12.3% on average in two years, one of which is the rapid growth of upgrading consumption. "VAT invoice data shows that in April, the national wholesale and retail sales revenue increased by 26.2% year-on-year, an increase of 26.1% over the same period in 2019, and an average increase of 12.3% in two years. Among them, the consumption of upgrades has grown rapidly, and the retail sales of watches, health care equipment, photographic equipment and nutrition and health products have increased by 21.6%, 46.7%, 9.4% and 25% respectively in two years. " Zhao Lianwei said.

In the construction industry, the sales revenue of the construction industry increased by an average of 14.5% in two years, and the construction of new infrastructure was accelerated. According to the data of VAT invoices, from January to April this year, the sales revenue of the national construction industry increased by 39.6% year-on-year, by 31.1% compared with the same period in 2019, with an average increase of 14.5% in two years, reflecting the continued recovery of investment. The investment structure was gradually optimized, and investment in new infrastructure increased.

In addition, State Taxation Administration of The People’s Republic of China also released the relevant data of newly established tax-related market entities. "Newly established" means that they have gone through the relevant procedures for the registration of market entities, and "tax-related" means that certain production and business activities have taken place. The data shows that thanks to the continuous release of a series of policy dividends, such as tax reduction and fee reduction, "streamline administration, delegate power, strengthen regulation and improve services" reform, and optimization of business environment, in April, there were 1.336 million new tax-related market entities, an increase of 5.1% compared with March, an increase of 21% and 20.3% respectively compared with the same period in 2020 and 2019, with an average increase of 9.7% in two years.

In terms of types, the number of newly-established individual industrial and commercial households reached 621,000, which is about half of the total number of newly-established businesses. The executive meeting of the State Council made it clear that we should continue to provide targeted support to small and micro enterprises and individual industrial and commercial households, including implementing tax reduction and fee reduction measures and helping them cope with the impact of rising prices of raw materials.

　Fan Chunhai is a member of the Central Committee of Jiu San Society, a professor at the School of Chemistry and Chemical Engineering of Shanghai Jiaotong University, and a member of the Shanghai Municipal Political Consultative Conference. In 2019, he was co-elected as an academician of China Academy of Sciences.

At the age of 26, he received a doctorate in biochemistry and molecular biology from Nanjing University.

At the age of 33, he was supported by the Outstanding Youth Fund of the National Natural Science Foundation of China.

At the age of 42, his team developed a new method for inducing nano-scale precise mineralization by DNA self-assembly structure, which was published in Nature, and achieved the first breakthrough in the field of DNA nanotechnology by China researchers.

He has been selected as a "highly cited scientist in the world" in the past six years.

At the age of 45, he was elected as an academician of China Academy of Sciences, the youngest among the Shanghai academicians in 2019.

He is Fan Chunhai, member of the Central Committee of the Jiu San Society, member of the Shanghai Municipal Committee of the Chinese People’s Political Consultative Conference, and director of the Shanghai Municipal Committee of the Jiu San Society.

Fan Chunhai’s office is located in the Translational Medicine Research Center of Shanghai Jiaotong University. Next to the simple and bright office is a uniform laboratory. The experimental platform is filled with all kinds of equipment. The window is bright and clean, with few other colors except black and white. Fan Chunhai, who has just been interviewed by his alma mater, is still immersed in the memories of middle school life. Talking about today’s achievements, he said with emotion: "These 20 years happened to be a period of rapid development in China, and the conditions and level of scientific research have undergone tremendous changes. I am glad to catch up with such a good era and let me make great achievements in scientific research."

Fan Chunhai belongs to the Ministry of Chemistry in the published results of the co-election of academicians of China Academy of Sciences. He once won the Tan Jiazhen Prize for Innovation in Life Sciences, one of the most influential awards in the field of life sciences in China. After returning to China, he chose the Shanghai Institute of Applied Physics of Chinese Academy of Sciences as his work unit. Under such a "cross-border", it seems difficult to define his professional field. His explanation for this is: "Subject field and research direction are different concepts, and my research direction has not changed for more than 20 years. I have been engaged in basic research on biosensing since I was a graduate student, just to explore the unknown world and need a broader vision. "

In 1992, Fan Chunhai, who was preparing to take the college entrance examination, applied for the Department of Biochemistry of Nanjing University. "At that time, the choice of biochemistry was blind and I didn’t understand it at all. But I vaguely feel that biochemistry has both biology and chemistry. This name is cool! " Fan Chunhai recalled.

樊春海在南京大学读书时，生物化学系就有浓郁的学科交叉氛围，系里的口号是“学不好化学，就做不好生物化学”。我国生物制药技术研发的开拓者之一，肝素、尿激酶工业的创始人朱德煦时任系主任，中国科学院院士、生命分析化学概念的创导者和生命分析化学国家重点实验室创始人陈洪渊的博士李根喜在生物化学系任教，樊春海在研究生期间得到他们的指导，在生物化学和生命分析化学两条学术传承线的交叉点起步，从事电化学生物传感器的研究，这在当时属于前沿交叉学科。

在前沿学科里不断前进，必须更多地了解国际上的科研动态，“我读书那会儿，经常需要看国外文献，遗憾的是那时看到的文献会滞后至少半年。”樊春海偶然读到《先进材料》（Advanced Materials）杂志对圣塔芭芭拉加州大学（UCSB）艾伦？黑格（Alan J. Heeger）教授（诺贝尔化学奖获得者）的专访文章。文章中黑格表示，自己在获诺贝尔奖后希望做一些以往不敢做的事，比如生物学，特别是生物传感方面的研究。樊春海内心有种一拍即合的快感，随即就向黑格教授申请了博士后，并最终获得认可。

Allen? Haig is a professor in the Department of Physics, but he always advocates interdisciplinary research. Many years later, Professor Haig said modestly in a speech in China: "I knew nothing about biology at that time, even the most basic knowledge such as DNA molecular structure was taught by Chunhai."

"Studying in a Nobel Prize winner’s laboratory, the vision of seeing problems and the way to deal with problems are very different from those in an ordinary laboratory." Fan Chunhai admits that when he was working as a postdoctoral fellow, he realized a deeper connotation about interdisciplinary. Working in Haig’s laboratory, Fan Chunhai had to carry out multiple scientific research projects at the same time, which once overwhelmed him. "You just pick the most important thing to do." This sentence of the tutor made Fan Chunhai enlightened, and he still often guides him to make judgments.

Under the guidance of Professor Haig, Fan Chunhai has made some research progress, and related research work has been published in authoritative magazines such as Proceedings of the National Academy of Sciences (PNAS) and Journal of the American Chemical Society (JACS). Among them, an electrochemical DNA biosensor named E-DNA has been developed, which has been widely praised by international peers. American Chemical Society C&E News rated it as one of the important chemical progress in 2003.

The postdoctoral experience has greatly broadened Fan Chunhai’s horizons and strengthened his confidence in interdisciplinary research. At that time, China was in the initial stage of discipline construction and needed a lot of new blood. In January 2004, Fan Chunhai joined sinap with the support of the "Hundred Talents Program" of China Academy of Sciences. Coincidentally, the day when he joined the defense was the day when the Shanghai Synchrotron Radiation Light Source Project undertaken by the Institute was approved after ten years of hard preparation. This internationally advanced synchrotron radiation light source was completed in only five years. The scientists who participated in the project are not afraid of hardships and hard work, and are praised as "Shanghai Light Source Spirit". In the past five years, under the inspiration of "Shanghai Light Source Spirit", Fan Chunhai built a laboratory from scratch.

In 2008, Fan Chunhai and others established a physical biology laboratory and set up a multidisciplinary research team integrating physics, chemistry and biology. This unique interdisciplinary research atmosphere not only enabled the biosensor research to advance rapidly, but also broadened more frontier research directions. In 2016, the important achievement of the laboratory, "Research on Mechanism, Regulation and Application of Biomolecular Interface", won the second prize of National Natural Science.

In recent years, Fan Chunhai’s team has applied biosensing probes detected in vitro to cells, and is committed to developing frame nucleic acid cell imaging technology. "It doesn’t matter what technology you use, physics or chemistry, or nanotechnology. What matters is that you find some new methods and use some new technologies to observe and decipher the mysteries of life."

"Individual growth cannot be separated from excellent collectives"

Fan Chunhai always appreciates the strength of the collective. Whether it is the study and life in middle schools and universities or the scientific research work, Fan Chunhai believes that the excellent collective has given him the motivation for personal growth.

He recalled that he was never the best student in middle school. "I am a person who knows by learning, not a person who knows by birth." In high school, many of my classmates were excellent. Everyone always discussed problems harmoniously and equally, forming a rich learning atmosphere. Under the professional guidance of teachers, everyone was growing and making progress. In the end, the whole class handed over an excellent answer sheet in the college entrance examination. "

There is such a collective star effect in scientific research, such as the famous Cavendish laboratory, which has trained more than 20 Nobel Prize winners in the past 100 years. "So scientific research has never been alone, and the progress of each group cannot be separated from individual efforts, and the growth of individuals cannot be separated from an excellent group." Fan Chunhai said.

At the beginning of this century, the scientific research conditions in Chinese universities were still relatively difficult, and the information was not as developed as it is now. It was the dream of many analytical chemists in China to be able to publish papers in Analytical Chemistry in the United States. At that time, only Mr. Chen Hongyuan in Nanjing University published papers in this magazine. Fan Chunhai published a paper in Analytical Chemistry as the first author under the guidance of his tutors, and achieved a breakthrough.

Interdisciplinary cooperation is also inseparable from the cooperation between scientists and the whole team. Fan Chunhai, deeply inspired by the "Shanghai Light Source Spirit", hopes to do the same internationally influential research work in Shanghai Institute of Applied Physics, Chinese Academy of Sciences. Mr. Li Mingan and researcher Hu Jun are early explorers in the cross-research of nano-organisms in China. With their guidance and help, Fan Chunhai gradually made it clear that DNA nanotechnology is the starting point to form research characteristics.

DNA nanotechnology is to use the excellent self-assembly and recognition ability of DNA molecules as a nano-material to achieve accurate nano-construction. In 2006, the nano-scale "Map of China" assembled by DNA molecules was successfully created and published in both Chinese and English editions of Science Bulletin, which made an international appearance with China characteristics and became the second published work in the frontier cross field of "DNA origami", which was jointly completed by Fan Chunhai, Hu Jun and Academician He Lin of Shanghai Jiaotong University.

After years of accumulation, Fan Chunhai’s team developed a new method to induce nano-scale precise mineralization by DNA self-assembly structure, which improved the mechanical properties of DNA nano-structure while maintaining its exquisite design, and opened a new door for the construction and analysis of bionic nano-channels. This research achievement was published in the journal Nature, which achieved the first breakthrough in this field by researchers in China.

During the epidemic in COVID-19, due to the lack of Covid-19 RNA reference materials, the performance of nucleic acid detection kits could not be evaluated, and the competitiveness of high-quality domestic kits could not be strongly proved. Faced with this situation, with the deep participation and support of Fan Chunhai’s team, Shanghai Jiaotong University and Shanghai Institute of Metrology and Testing Technology jointly set up a research team and started the research and development project of Covid-19 RNA reference materials. After more than 40 days of repeated trials and improvements, two kinds of "novel coronavirus standard materials for RNA transcription in vitro" were successfully developed. These Covid-19 reference materials, like a "biological standard ruler", can help people to evaluate the indicators of the virus nucleic acid detection kit and help the detection laboratory to confirm the results, thus further reducing the probability of "false negative".

Facing the students from different majors in the team, Fan Chunhai advocates teaching students in accordance with their aptitude and effective guidance. "Students are not managed, but grow up freely under appropriate guidance. My task is to tap students’ interest in scientific research, help them establish correct values and lofty aspirations, and become firm supporters of students."

The road of scientific research has always been bumpy. The life of researchers is more like an ascetic monk to many people, but in their hearts, they are happy because of their love for science. In Fan Chunhai’s view, this happiness is not equal to comfort. He encourages students: "To do scientific research, we should be brave enough to go out of our comfort zone and challenge new things."

"Teamwork and independent thinking are equally important. I hope that every student can choose his own topic under the background of team research, and actively explore various possibilities without relying on authority." Despite his busy work, Fan Chunhai will try his best to take time to communicate with the students face to face, not sitting in danger, but full of relaxation and pleasure.

Fan Chunhai always tries his best to support and encourage students’ decisions and every attempt. Under his training, two students have been supported by the National Science Fund for Distinguished Young Scholars, and four postdoctoral students have been selected for the "Super Postdoctoral Program" in Shanghai in 2020.

Communication and cooperation promoted Fan Chunhai’s scientific research work, and also made him know Li Xinxin, chairman of the Shanghai Branch Committee of the Shanghai Municipal Committee of the Chinese Academy of Sciences of the Jiu San Society. The warmth of the Jiu San Society and the spirit of patriotism, democracy and science attracted him. In 2014, he joined the Jiu San Society.

After joining the club, Fan Chunhai successively served as deputy director and director of the Shanghai Municipal Committee of the Jiu San Society. Although his scientific research work is still busy, he will still find time to engage in popular science work. "Popular science work is actually a kind of inheritance. Whether it is exploring the unknown world or promoting the country’s scientific and technological development, it needs the efforts of generations. However, the concept of scientific research is not exactly the same as that of textbook education in primary and secondary schools. Our popular science work is not a simple strengthening of textbook knowledge, but a broader vision for children. "

In his mind, interests are hierarchical. The interests of primary and secondary school students are often in textbook knowledge and the use of known world knowledge, while real scientific talents need to keep their interest in exploring the unknown world. Spreading the seeds of science in children’s little hearts will not only keep them interested in exploring the unknown world, but also make the city form an atmosphere of obeying and respecting science, which is also the future light of the construction of Shanghai Science and Technology Innovation Center.

Looking back on his own growth experience, Fan Chunhai said with emotion: the cultivation of quality is more important, and the knowledge learned by the school is constantly updated, and the quality cultivated by the school will accompany people all their lives, and good quality will push people forward.

Good quality also made Fan Chunhai on his way to school recognized by teachers. "I am very relieved about what I have told him. No matter whether I get satisfactory results or lessons from failure after completion, he will definitely reply to me and have a serious discussion with me." Professor Li Genxi said of his students, "He is patient in learning and can hold his breath. Once his goal is set, he will be firm and forge ahead. His success is no accident."

In the interview, Fan Chunhai rarely talked about specific difficulties, because he believed that difficulties always existed, and problems could be solved as long as he worked hard and was good at learning and observing. In the communication with his students, Fan Chunhai has always conveyed a belief: optimistic and unyielding. "The development of science is not a full stop, but a comma. The success of scientific research depends on whether you have the courage to face failure and the determination to be more frustrated on the road of exploration. I hope that all students can work hard for the scientific dream of mankind."

It has been nearly thirty years since I entered the university and contacted the interdisciplinary subject of biochemistry. Along the way, Fan Chunhai has grown from an ignorant teenager to an internationally renowned scientist: he was selected as a Fellow of American Association for the Advancement of Science (AAAS), American Academy of Medical and Biological Engineering (AIMBE), international society of electrochemistry (ISE) and royal society of chemistry (RSC), and concurrently served as the deputy editor of ACS Applied Materials & Interfaces Journal of American Chemical Society. Co-chairman of the editorial board of ChemPlusChem, royal society of chemistry, has been selected as a "global highly cited scientist" continuously since 2014. In 2019, he was elected as an academician of China Academy of Sciences, and won the ho leung ho lee foundation Science and Technology Innovation Award, the American Chemical Society’s Lecture Award for Progress in Measurement Science and the 12th Tan Jiazhen Life Science Innovation Award, and in 2020, he was awarded the title of "National Advanced Worker".

Faced with many honors, Fan Chunhai said calmly: "It is curiosity, responsibility and initial heart that lead me to climb to the peak on the road of science." In the future, he said that he will continue to keep his initial heart and forge ahead, lead students to "look up at the stars, be down-to-earth, persevere and make contributions for a long time", constantly explore the frontiers of science, and make due efforts to promote the scientific and technological progress of the country and society.

Fan Chunhai’s goal is to promote his basic research work to clinical application and protect human health. After joining the School of Chemistry and Chemical Engineering of Shanghai Jiaotong University, Fan Chunhai built the laboratory of "Framework Nucleic Acid Design and Nano-medical Diagnosis and Treatment" based on the newly completed national major scientific and technological infrastructure of translational medicine, and devoted himself to transforming and applying the developed new methods of nucleic acid analysis and detection to clinic. In particular, he received the full support of Academician Tan Weihong, Dean of the Institute of Molecular Medicine of Shanghai Jiaotong University, and actively carried out clinical cooperation in Renji Hospital, trying to apply biosensors to the detection of practical clinical samples such as prostate cancer, and exploring the possibility of developing low-cost medical detection.

"The road is long and Xiu Yuan is awkward, and I will search up and down." Fan Chunhai is still moving forward on the road of seeking. In 2019, in order to commemorate the tenth anniversary of the publication, "Nature? The magazine Nature Chemistry specially invited more than 50 internationally renowned scholars to write a monograph on "The Road to Chemistry". As one of them, Fan Chunhai raised a challenging question in the field of chemistry: "An exciting frontier of the discipline is to understand how artificially designed nucleic acid structures are assembled and function in living cells and animals. Creating new tools to control the assembly process of natural and artificial nucleic acid molecules in living cells will probably bring revolutionary changes to the field of nucleic acid chemistry, thus promoting the development of nano-diagnosis and treatment and precision medicine. In the longer term, another promising research direction is to explore and develop DNA or RNA robots with artificial intelligence and work in animals and humans. " (Huang yun)
