Zhangzhou, China, April 15 (Reporter Bai Jiege) According to the Voice of China report, people who have played real CS are no strangers to simulation guns. However, a Fujian teenager never imagined that an online shopping brought him jail. Two years ago, 18-year-old Xiao Liu bought 24 "simulation guns" online from a seller in Taiwan Province, but they were seized by the customs. After identification, 20 of them turned out to be guns.

　　In August 2014, he was sentenced to life imprisonment for the crime of smuggling weapons. The court held that buying and selling simulation guns was prohibited by law, and the smuggled simulation guns were identified as guns, which constituted the crime of smuggling weapons, and the circumstances were particularly serious.

　　Although it is final, lawyers believe that the details of the purchase link are still controversial. This week, the Higher People’s Court of Fujian Province has filed a case for review. So, how did the simulation gun become a real gun?

　　The last time Ms. Hu saw her son Xiao Liu was on March 20th this year. She visited Zhangzhou Prison in Fujian once a month. Ms. Hu said that he was very pessimistic. He always feels that he has been sentenced to life imprisonment, and no matter how good his performance is, he will be about our age.

　　In 2014, at the age of 18, Xiao Liu bought 24 "BB guns for survival games" from a seller in Taiwan Province through the Internet in his hometown in Sichuan, with a total price of 30,540 yuan.

　　Ms. Hu said that she knew that he had discussed with herself, "He likes to play this game. We also told him at that time, so just buy one or two, not so many. He told us that if one or two were delivered in Taiwan Province, it would take 30,000 yuan to deliver the goods."

　　Xiao Liu didn’t get these guns, but waited for the customs staff at home: "The money was later returned. I heard that the seller told my son that this thing was detained by the customs and I will return the money to you." Ms. Hu said that it took more than a month from buying things to returning money, and it took more than half a month for people who came to the customs to go home.

　　Ms. Hu said that at first they didn’t realize the seriousness of the problem: "Because they didn’t receive anything, they didn’t see anything. We think it may be closed at most and will be released in a few months. "

　　On September 29th, 2014, Xiao Liu was arrested on suspicion of smuggling weapons. On April 30 last year, he was sentenced to life imprisonment by the Intermediate People’s Court of Quanzhou City, Fujian Province for smuggling weapons. On August 25, the Higher People’s Court of Fujian Province rejected the appeal and upheld the original judgment.

　　Lawyer Xu Xin, a professor at Beijing Institute of Technology Law School, became Xiao Liu’s defender after this. Last November, he met with Xiao Liu: "His state is very bad, and he feels very wronged and incomprehensible. He said that he just had such a hobby, and he was suddenly sentenced, and it was life imprisonment. He felt that life was hopeless and desperate. "

　　Combined with the materials written by Xiao Liu, Xu Xin filed a plea of innocence with the Higher People’s Court of Fujian Province: the main reason for making a plea of innocence is very sufficient, because one of the biggest problems found in the process of studying this case is that it is very likely that his simulation gun was not bought by the party concerned.

　　Xu Xin said that the judgments in the first and second instance only proved that Xiao Liu was shopping with a seller named "Blue Sea and Blue Sky" and that a couple from Taiwan Province delivered goods to Xiao Liu, but it could not prove that the couple from Taiwan Province were "Blue Sea and Blue Sky": "The key problem is that the guns he bought are different from the guns he was detained at last. The biggest difference is that the four long guns he bought are all rechargeable, but all the detained guns are inflatable."

　　Xu Xin also questioned some evidence in the judgments of the first and second instance. He said that Xiao Liu only bought a toy gun, and there was no subjective intention and no harm: he bought a gun for his own fun and collection, and subjectively there was no criminal intention. And objectively, he didn’t commit a crime. He didn’t get the gun at all, and objectively, he didn’t receive it.

　　For a non-standard gun that can’t fire standard ammunition, it also looks like a gun. Is it a real gun or a simulation gun in law? In the "Regulations on Performance Appraisal of Firearms and Ammunition Involved by Public Security Organs" issued by the Ministry of Public Security of China in 2001, the judgment standard is to shoot with a dry pine board with a thickness of 25.4mm, and the muzzle is 1 meter away from the board. If the warhead penetrates this pine board, it is judged that this gun is enough to cause death; The bullet or shrapnel stuck on the pine board, which proves that the gun is enough to hurt people. The above two cases are identified as guns, that is, real guns. In 2010, the Ministry of Public Security revised the "Work Regulations", which did not mention the identification method of this experiment, but clearly stated that the muzzle specific kinetic energy of the projectile fired was greater than or equal to 1.8 Joule/cm2, and it was all recognized as a gun. In 2007, the related Standards for Identification of Simulation Guns and Criteria for Forensic Scientific Appraisal of Guns’ Injuries have already mentioned the demarcation value of 1.8 Joules/cm2, which is based on the fact that it can affect the most vulnerable part of human body — — Bare eyes cause minor injuries, but they cannot penetrate the skin.

　　The change of this standard has caused controversy. Xiao Liu’s defense lawyer Xu Xin said: "His case involves the biggest problem, and it is also the biggest motivation for me to pay attention to this case because it involves more and more ordinary people. Because of the current identification of China simulation gun, the standard for identifying it as a real gun is very low, that is, the muzzle specific kinetic energy is 1.8 Joule/cm2, which is equivalent to one-ninth of the standard in 2001, which is much lower than the old standard. Only one red dot can appear at close range, and the skin can’t be injured. "

　　According to the inquiry of Zhu Zhengfu, a member of Chinese People’s Political Consultative Conference, the standard for determining the lethality of firearms in Japan and Taiwan Province is 20 Joules/cm2, which is 11 times that of the current standard of China Ministry of Public Security. Therefore, guns that are legal toys in neighboring countries and regions will be identified as "guns with China characteristics" as soon as they enter the country, and the punishment for the relevant parties will be the same as the real gun case. Therefore, in the proposal of the National People’s Congress this year, Zhu Zhengfu proposed to re-examine the relevant gun identification standards.

　　In order to visit his son and complain about his case, Xiao Liu’s parents left their hometown in Sichuan and went to work in Fujian. Xiao Liu’s mother, Ms. Hu, said that they had been unable to contact the sellers in Taiwan Province after the incident. She learned this week that the Fujian Provincial High Court has filed a case review of Xiao Liu’s case.

　　Some media also quoted the relevant person in charge of the Fujian Provincial High Court to confirm this statement.

　　The State Council, the Central Committee of the Communist Party of China recently issued "Several Opinions on Improving the System and Mechanism of Promoting Consumption and Further Stimulating the Consumption Potential of Residents".

　　Recently, although the Korean entertainment circle is shrouded in the shadow of star suicide, many stars have made their love affairs public. Cui Zhiyou and Li Zhenxu, Li Dongjian and Ye-ryeon Cha, Jiang Huizhen and Tablo, Han Gaoen and Jin Dongyuan have all become the targets of media pursuit, which is enough to sweep away the haze caused by suicide. According to media analysis, the biggest driving force for artists’ open love affair is the global financial crisis.

　　In February, Tablo, who disclosed the fact of love, once again disclosed the intimate photos with her lover Jiang Huizhen, and they showed their love at the dinner table. At the same time, Tablo also expressed his endless affection for his lover in his blog.

　　Active exposure type

　　Jiang Huizhen and Tablo

　　Jiang Huizhen, an actress, is much more high-profile. She recently made it public on a TV program that she is in love with the singer Tablo. She revealed that since the public affair, they don’t have to secretly date as before, so they feel very comfortable. According to reports, the two met through friends at the end of last year and soon developed into lovers. After that, Tablo also talked about love generously: "I feel very happy because she is here. She always brings me endless energy. I really appreciate her."

　　Coincidentally, Han Gaoen, an actor, suddenly exposed a new love affair on a TV program a few days ago: "I have a lover who has known each other for about 12 years and dated for 2 months. He is not an actor, and we have a good relationship. " As soon as this remark came out, it attracted media speculation. After verification, it was found that it was director Jin Dongyuan who captured Han Gaoen’s heart. After he became famous as an advertising director in the 1990s, he broke into the Korean film industry in 2006 through the popular film "One Head and One Master". The fate of the two can be traced back to 12 years ago. Han Gaoen’s first advertising work was written by Jin Dongyuan. Last November, the two quickly developed into lovers in the process of filming the movie "The City of Regret".

Han Zhihui was photographed by a Korean media when they went hiking together for a date.

　　Han Zhihui fell in love with the prosecutor.

　　Generally, artists meet secretly in the parking lot in front of their homes for fear of exposure. On the contrary, actor Han Zhihui (25 years old) enjoys public dating happily. At present, she is in love with A Jun, a prosecutor who is six years older than herself, and Han Zhihui also admitted that they have recently started dating since they met in January this year.

　　Mr. A, the hero who won Han Zhihui’s heart, is an elite prosecutor. Although he has not been in office for a long time, he has been recognized by his colleagues and predecessors with his honesty. A Jun not only graduated from Seoul National University, the highest institution in Korea, but also passed the judicial examination. He is a talented person with a bright future.

　　Xinhua News Agency, Valletta, May 5th(International observation) EU sanctions stick to Russian oil, European economy may be more hurt.

　　Xinhua News Agency reporter Chen Wenxian Li Jizhi

　　On the 4th, the European Commission formally submitted a new round of sanctions, including an oil embargo on Russia, and once again swung the sanctions stick at the Russian energy sector. The analysis believes that once the oil embargo is imposed on Russia, the European energy crisis will further deepen, ordinary families will bear higher energy bills, and the operating costs of related industries will also be raised, which will lead to an increase in the risk of European economic stagflation.

　　The energy crisis worsened.

　　The proposal of the sixth round of sanctions against Russia submitted by the European Commission on the 4th includes a total ban on the import of Russian oil by the end of this year, that is, the EU will gradually phase out Russian crude oil within six months and Russian refined oil by the end of this year.

　　After the EU announced on April 8 that it would stop importing Russian coal from August, the EU once again "cut the knife" to Russian energy to achieve the goal of greatly reducing its dependence on Russian energy. At present, about 40% of natural gas, about 30% of oil and slightly less than 20% of coal imported by the EU come from Russia, and Russian energy plays an important role in the EU energy consumption market and economic development.

　　Sanctions against Russian oil are a "double-edged sword" for the EU. While Russia’s oil revenue is greatly reduced, it is difficult for the EU to seek alternative sources from the already tight international market in a short time, and its own energy crisis will intensify.

　　Russia expects oil production to drop by about 17% this year. Market analysts believe that the reduction of Russian oil production will make the global oil supply more tense and aggravate market worries, and oil prices are expected to soar again.

　　Michael Holstein, chief economist of the German Central Cooperative Bank, believes that the oil embargo against Russia may continue to push up oil prices in the next few months, and the German inflation rate may remain at a high level for a long time.

　　There are obvious internal differences

　　Just as EU member states hold different opinions on Russian natural gas "ruble settlement order", countries also have differences on sanctions against Russian oil. There has been a heated debate within the EU for some time, but the final plan has not yet been fully agreed, and there are certain variables in the details of the plan.

　　Since the escalation of the conflict between Russia and Ukraine, the EU has repeatedly expressed its desire to "get rid of" Russian oil and gas in the round after round of sanctions, but it is quite difficult for the EU to really do this.

　　The sanctions against the Russian oil embargo need to be unanimously agreed by 27 member States before it can take effect. Ursula von der Leyen, president of the European Commission, admitted that it was not easy to pass the proposal because some member countries were highly dependent on Russian energy. At present, Hungary, Slovakia, the Czech Republic, etc. all said that they could not find alternative sources quickly and needed a long transition period.

　　Gullyas Gergely, Minister of the Hungarian Prime Minister’s Office, said that Hungary was "ready to veto" the relevant proposal, and it would take about five years and cost "a lot of money" to switch oil and gas sources.

　　Stagflation risk intensifies

　　Soaring energy prices, record high inflation and supply chain shortage have aggravated the risk of stagflation in Europe, which will hinder the recovery after the COVID-19 outbreak. According to Eurostat data, the euro zone economy grew by only 0.2% in the first quarter, while the inflation rate was as high as 7.5% in April.

　　The report of Bruggaier Institute, a Belgian think tank, said that the embargo on Russian oil would have negative consequences for the EU, at least in the short term, causing losses to the EU and the whole world economy.

　　Sarah Mathieu, a member of the European Parliament, said that these sanctions will not only harm the Russian economy, but also "affect the housing, jobs and wallets of EU people", which may increase social inequality, push up unemployment and aggravate energy poverty.

　　Eugenio Pinto, a professor of economics at Rome International Free University of Social Sciences, said in an interview with Xinhua News Agency that if countries that are highly dependent on Russian energy stop importing Russian energy, they will be forced to adopt an energy quota system and their economic recovery will come to a standstill.

　　Peter Adrian, president of the German Chamber of Commerce and Industry, said that rising oil prices will increase the financial pressure of enterprises, especially for energy-intensive industrial and logistics enterprises. In extreme cases, enterprises may be forced to close down for cost reasons.

　　Molditz Jobaugh, research director of Eurasian Center of Hungarian john von neumann University, said in an interview with Xinhua News Agency a few days ago that sanctions alone will not help to solve the conflict between Russia and Ukraine, and negotiations must be held, because it is not a good solution to completely cut off diplomatic, economic and commercial ties with Russia.

　　[car home Engine Analysis] Today, with the increasing popularity of electric vehicles, many manufacturers are still insisting on the development of internal combustion engines. After all, in the domestic and even global markets, oil vehicles still have an irreplaceable position in many application scenarios. Speaking of SAIC MAXUS, many consumers may immediately think of their hard-core SUVs, pickup trucks and RV products, and today it is from SAIC MAXUS Xuanyuan Power that we want to talk about.

　　Speaking of diesel engines, in the traditional cognition of many consumers, diesel engines have the advantages of durable leather, high torque, low fuel consumption, etc., and are suitable for use on complex roads, climbing hills, heavy loads, etc., so they are also the first choice for many hard-core off-road vehicles. However, noise, pollution and other problems have also discouraged many consumers. What changes can diesel engines make in the hands of SAIC Chase engineers?

What is SAIC Chase Xuanyuan Power Technology?

　　The brand-new SUV territory of SAIC Chase MAXUS is equipped with the first diesel light hybrid power technology in Asia, which combines a 2.0T SAIC π Bi-Turbo double supercharged diesel engine, a ZF 8AT automatic transmission and a 48V hybrid architecture. The technology is named "SAIC Chase Xuanyuan Power Technology", and this diesel engine has also won the reputation of "Top Ten Engines of China Heart" in 2020.

2.0T SAIC π Bi-Turbo Dual Supercharged Diesel Engine

　　As one of the top ten engines of the year, this 2.0T twin-supercharged engine has its own good skills, and it is also the core of this Xuanyuan power. Let’s take a look at what "black technologies" it has.

　　The vehicle adopts WGT+VGT two-stage turbocharger, which is adjusted by three vacuum valves to realize the free switching between high and low pressure stages, and has three working modes, namely, the low-speed stage uses small blades, the middle-speed stage uses two blades at the same time, and the high-speed stage uses large blades, which improves the engine efficiency. When the engine speed is 1000rpm, the turbine will intervene and reach the maximum torque output at 1500rpm, which will increase the low-speed torque and power of the vehicle by 15% and 30%.

　　The water-air intercooler adopts water cooling and air cooling at the same time. Under the same air-fuel ratio, the engine power will increase by 3%~5% for every 10℃ drop in the temperature of pressurized air.

　　At the same time, this engine also applies the intelligent single-axis continuous variable vortex control valve for the first time. When the engine is in high working condition, the control valve will open a relatively flat intake port, so that air can enter the engine cylinder quickly and smoothly. When the engine is under low load, the control valve will open the air passage with spiral cross section to help the air entering the engine cylinder produce better vortex effect, so that the pressure difference of each cylinder can be less than 3%, and the air intake can be more uniform, thus making the combustion of each cylinder of the engine stable, achieving smoother power output, and reducing the emission of particles and carbon monoxide and fuel consumption.

　　This diesel engine adopts a two-stage variable oil pump, which can adjust the oil pump flow in real time according to different speed loads while meeting the oil pressure demand. Low-pressure mode is adopted at medium-low speed and medium-low load; When there is a high speed and high load demand, the high pressure mode is adopted. Through adjustment, the oil pump can run at the lowest energy consumption, thus reducing fuel consumption. Through the NEDC (New European Cycle Test) cycle test, the fuel consumption of the whole vehicle can be reduced by 2~3%;

　　In addition, this diesel engine is equipped with a double-shaft balancing mechanism and a double-loop EGR system, in which the balancing shaft is asymmetrically arranged to balance the engine covering torque, which greatly reduces the second-order vibration, makes the engine run more smoothly, and also reduces vibration and noise. The dual-loop EGR system can reduce the warm-up time, reduce fuel consumption and improve the heating effect of air conditioning. (EGR is the full name of exhaust gas recirculation system. By re-injecting some exhaust gas into the engine cylinder, the combustible mixture is diluted and the combustion efficiency is reduced, so as to achieve the purpose of controlling the working temperature of the engine, reducing Nox emission and reducing urea consumption. )

　　In addition to the above, this diesel engine also adopts Bosch’s ultra-high pressure fuel injection system, which can obtain more accurate fuel supply control, and crankshaft offset technology, which can effectively reduce the running noise and wear of the engine piston. At the same time, a number of NVH optimizations have been carried out.

48V light mixing system

? The 48V light mixing system of the vehicle adopts Valeo 48 BSG motor, with special bidirectional tensioner, and the gear train speed ratio is as high as three times, which further amplifies the output torque of 48V BSG and effectively improves the low-speed torque characteristics of diesel power. When the 48V battery is charged, the engine is started by BSG, and the vehicle starts more smoothly, the starting time is shortened from the traditional 0.6 seconds to 0.3 seconds, and the starting noise is reduced by 10-15 dB. With the assistance of the motor, the torque of the power system is increased by more than 30%, and the starting acceleration of the vehicle below the medium and small throttle of 30%-50% is increased by more than 33%; 0-100km/h acceleration time is shortened by 0.4 seconds.

　　In addition to performance, fuel economy has been further improved. Under high-speed working conditions, the surplus torque of the engine drives the 48V motor to charge and store energy. The fuel consumption under WLTC can be saved by 8%, while Nox emission can be reduced by more than 50% in RDE test at most.

The first China Cross-border E-commerce Fair was held in Fuzhou, Fujian this year. Buyers learned about the products on display in front of a 3C product booth. Xinhua News Agency reporter Lin Shanchuan photo

Starting from September, the parcels collected through the warehouses in Yiwu or Shenzhen’s core industrial belt can fly directly to Southeast Asian destinations from the nearest air port. "Most parcels can be delivered door-to-door in 3 days, and can be delivered to consumers within 48 hours at the earliest.".

This is the cross-border express logistics service from China to Xinmatai officially launched by Best International in China International Fair for Trade in Services in 2021 not long ago. The business accurately points to the trend of multi-polarization of cross-border e-commerce in Southeast Asia, showing that China’s cross-border e-commerce continues to maintain a good momentum and has become a new fulcrum in the rapid growth of foreign trade.

"From January to June this year, the import and export volume of cross-border e-commerce was 886.7 billion yuan, a year-on-year increase of 28.6%." At the Cross-border E-commerce Forum of "2021 China E-commerce Conference" held recently, Zhang Li, deputy director of the Foreign Trade Department of the Ministry of Commerce, said that cross-border e-commerce has become a new foreign trade format with the fastest development, the greatest potential and the strongest leading role in China.

Stimulate market vitality

In recent years, under the background of the deep integration of the Internet and economic globalization, the global trade format has undergone major changes, and the new economic form of "digital trade" represented by cross-border e-commerce has achieved rapid development from scratch and from small to large.

Zhang Dawei, vice chairman and secretary general of China International Economic Exchange Center, said recently that China’s series of measures to support the development of cross-border e-commerce have greatly stimulated the market vitality of cross-border e-commerce, played a pulling role in the global cross-border e-commerce market, and enabled countless small and medium-sized enterprises and practitioners to directly integrate into the global industrial chain supply chain and directly enter the global consumer market.

"Cross-border e-commerce is favored by consumers around the world with its unique advantages of low cost, high efficiency and breakthrough in time and space." Hong Yong, an associate researcher at the E-commerce Research Institute of the Ministry of Commerce, said that in recent years, the scale of cross-border electronic commerce transactions in China has continued to grow, and it has become a new kinetic energy for foreign trade development, a new channel for transformation and upgrading, and a new starting point for high-quality development.

Sang Baichuan, president of university of international business and economics Institute of International Economics, believes that with the help of the Internet platform, new trade modes such as cross-border e-commerce have greatly satisfied the information symmetry between the supply and demand sides, and also improved the efficiency of bilateral trade. At the same time, because China’s product system is complete, it can provide products to other countries on a large scale and in a concentrated way, reducing import and export costs, thus meeting the needs of consumers and investors. It can be said that a large number of products with high quality and good price are also the reasons for the rapid development of cross-border e-commerce in China.

Last year, when the COVID-19 epidemic had a profound impact on the global supply chain and traditional economic and trade activities, cross-border e-commerce in China bucked the trend, achieving an annual import and export volume of 1.69 trillion yuan, up 31.1% year-on-year, nearly 10 times the scale five years ago, which strongly supported the growth of China’s import and export trade. In July this year, the General Office of the State Council issued the "Opinions on Accelerating the Development of New Foreign Trade Forms and Models", which once again released major favorable policies in the field of cross-border e-commerce.

Improve the institutional framework

Since 2015, China has set up 105 cross-border e-commerce comprehensive experimental zones in five batches, covering basically the whole country. The scale of the "experimental field" where cross-border e-commerce is tried first has been continuously expanded, and the development pattern of land and sea linkage and two-way mutual assistance between east and west has been further improved.

"The Ministry of Commerce and other departments have formed nearly 70 mature experiences and practices through active exploration, and built a cross-border e-commerce system framework with’ six systems and two platforms’ as the core." Hong Yong said that, for example, China’s customs declaration mode of "list verification and summary statistics" has improved customs clearance efficiency, and cross-border e-commerce tax preferential policies such as approved collection have greatly reduced the burden on enterprises. The scope of cross-border e-commerce B2B export supervision pilot and retail import pilot continued to expand. The list of cross-border e-commerce retail imports was further optimized to better meet domestic consumer demand. In addition, a series of regulations on the management of cross-border e-commerce import and export returns have been issued, which makes it more convenient for consumers to return goods.

According to Wei Hao, a professor at the School of Economics and Business Administration of Beijing Normal University and director of the Department of International Economics and Trade, the support policies for cross-border e-commerce should focus on the pain points and difficulties in the development of cross-border e-commerce and put forward pragmatic measures that meet the expectations of enterprises. "We must not only solve the short-term problems that restrict development, but also pay attention to the improvement of infrastructure and mechanisms for long-term development."

In the short term, we should attach great importance to the construction of overseas warehouses, focus on strengthening subject cultivation, promoting digital development, strengthening standard construction and improving overseas warehouse network, and support the construction of overseas warehouses with various investment and financing methods and increasing export credit insurance. In addition, it is necessary to constantly improve the management policies for cross-border e-commerce import and export returns and ease the operating pressure of enterprises, especially small and medium-sized enterprises.

In the long run, it is necessary to study and formulate intellectual property protection policies for cross-border e-commerce, improve various support policies such as finance and taxation, vigorously cultivate large-scale international logistics enterprises, explore the construction of overseas logistics intelligent platforms, build independent large-scale international e-commerce platforms, and strengthen infrastructure construction, so as to lay a solid foundation for the long-term development of cross-border e-commerce.

Dealing with development risks

At present, China’s cross-border e-commerce has also encountered some bottlenecks in its overseas development. Due to the different laws, cultures and business habits of different countries, cross-border e-commerce businesses will encounter various risks and challenges.

"This is an inevitable problem in the development of the industry." Hong Yong said that some cross-border e-commerce merchants were forced to be removed from the cross-border e-commerce platform on a large scale because they were suspected of violating the rules of the platform by brushing bills and comments. In addition, affected by the rebound of COVID-19 epidemic, the international shipping price has been rising, and the profits of cross-border e-commerce enterprises have also been severely squeezed.

"These problems highlight the unstable foundation for the stable development, rapid development and long-term development of cross-border e-commerce in China, the imperfect mechanism and system, and the development environment still needs to be optimized." Wei Hao believes that the main reasons for these problems are the lack of independent e-commerce platform, especially the support of a large platform with a large international market share, insufficient international logistics and transportation capacity suitable for the rapid development of cross-border e-commerce, insufficient understanding of relevant rules in developed countries such as Europe and the United States, need to pay more attention to intellectual property protection, and lack of awareness and ability to deal with international risks.

Wei Hao said that we should speed up the construction of cross-border e-commerce online integrated service platform to reduce the burden on enterprises and improve efficiency; It is necessary to attach great importance to regulatory issues such as risk prevention and control, standardize the development of the industry, and enhance the ability of the industry to cope with risks; Steadily promote the construction of cross-border e-commerce comprehensive experimental zone, provide a leading role for the future development of cross-border e-commerce, and actively copy and promote the mature experience and practices of cross-border e-commerce comprehensive experimental zone to the whole country.

Speaking of the future development of cross-border e-commerce, Hong Yong believes that we should focus on the functions of overseas warehouses, the protection of intellectual property rights and the establishment of international rules for cross-border e-commerce. At present, most overseas warehouses do not have the functions of providing customs clearance services, supply chain financial services, after-sales services and personalized services. At the same time, some products of cross-border e-commerce sellers involved in intellectual property infringement, which also affected the overall image of China sellers to some extent. Due to the different development priorities and interests of cross-border e-commerce in different countries, no unified international rules for cross-border e-commerce have yet been formed. China should actively participate in international exchanges and rules exploration of cross-border e-commerce, and launch the "China Program" for cross-border e-commerce in the multi-bilateral cooperation mechanism. (Reporter Feng Qiyu Ji Leilei)

　　Cctv newsOn April 23rd, 2020, the State Council Press Office held a press conference to introduce the development of intellectual property rights in China in 2019 and answer questions from reporters.

　　The reporter asked what new progress has been made in the construction of China’s intellectual property operation system in 2019.

　　Shen Changyu, director of China National Intellectual Property Administration, said that intellectual property work is a chain, which includes creation, protection, application, management and service. Creation is the source, application is the purpose, protection is the core and management is the key. Among them, application is a very important purpose of intellectual property, and it is a key link to promote the realization of intellectual property value and promote economic innovation and development. Relevant statistics show that in recent years, China’s comprehensive development index of intellectual property rights has been continuously improved, and the application of intellectual property rights has made remarkable progress.

　　In 2019, the number of patent transfer, licensing and pledge operations nationwide reached 307,000, a year-on-year increase of 21.3%. The amount of patent and trademark pledge financing reached 151.5 billion yuan, a year-on-year increase of 23.8%. The turnover of technology contracts involving intellectual property rights in China reached 928.69 billion yuan, up 137.7% year-on-year. A number of intellectual property operation projects and platforms are also accelerating. By the end of 2019, the number of key cities for the construction of intellectual property operation service system has increased to 26, and 9 national intellectual property operation platforms have listed 121,000 pieces of various intellectual property rights, with 284,000 registered users. The construction of intellectual property operation system has achieved new results.

What would it be like if Apple released a pair of AR glasses?

It has been ten years since Steve Jobs left us, but people will still miss the amazing feeling brought by the first generation and the classic design of the iPhone 4. When it comes to the impression of the Cook era, people are keen to discuss only the "little bangs", some product details of Pro Max’s lidar scanner and Apple’s market value of $3 trillion.

What will Cook bring to Apple? The question that everyone has been thinking about seems to have a new answer recently. Recently, when Cook was interviewed by many media, he called himself the "number one fan" of AR, and even said, "We don’t talk about the meta-universe, we only talk about AR". Therefore, AR glasses are most likely to become one of the iconic products of Apple in the Cook era.

Apple’s products have always been known for their high aesthetics, high standards and strict requirements. Cook once said that there is no AR glasses on the market that can satisfy him. Just like before Apple officially launched the AppleWatch, Cook also said something similar, saying that no wearable product satisfied him. So what kind of AR glasses does Cook want to make? Can it reproduce Apple’s past glory and lead a new consumption storm again?

These questions have made people pay close attention to the dynamics of Apple’s AR devices, and they all want to know what the AR glasses made by Apple will look like. We look forward to Apple’s AR glasses with you by taking stock of the information of Apple and Apple’s AR equipment.

Of course, the related AR patents may also be applied to head displays, mobile phones, watches and even automobiles. After all, Apple is making more and more money, and the consumer business involved is getting wider and wider. However, as the first AR device, AR glasses are still very likely to be applied to these patented technologies.

What are the highlights of Apple’s upcoming AR glasses that are worth looking forward to? By reading the patent documents, we infer that Apple AR glasses may have the functions of environmental application model, object-centered scanning, establishing virtual space and providing spatial audio.

▲ Apple obtained a summary of patent information related to AR glasses in 2021.

In this year’s 11 patents, we saw three more interesting patents, which also decrypted the "true face" of Apple’s AR glasses.

1. You can draw a floor plan by taking a picture. Is it a necessary "artifact" for designers?

In the past, people mainly used tape measure to measure the room area. This method was time-consuming and laborious, but if people put on Apple’s AR glasses, they might be able to get the floor plan of the room by looking around.

Moreover, because there are objects such as tables and sofas in the indoor environment, the lines of the room will be blurred, which makes it difficult for people to build accurate floor plans according to videos and sensors.

Faced with these problems, Apple chose to measure the structure of the room and create a floor plan through 3D Point Cloud technology and 3D display technology. These technologies mark the boundaries, walls, doors and windows in the room through words or symbols, and have special measurement methods.

▲ Measure the structure of the room through the camera head.

In this way, users can preview the floor plan of the room in real time while wearing AR glasses.

2. How will Apple create a "metauniverse"? Build an avatar to play first.

Apple has previously released the function of imitating my expression, which can imitate the user’s expression synchronously. Originally, the mimetic expression only imitated the user’s head movement, but now this range can be extended to the whole body. This patent is mainly designed for HMD at present, but it may be applied to some AR products in the future.

This technology will collect your posture information through multiple cameras, and you can customize a virtual avatar. Similarly, your avatar will change according to your movements. For example, if you talk and gesture, your avatar will also talk and gesture. This will enrich the creative form of video, and it may have a wider application range when linked with game products.

▲ Similar to Doug Roble, director of software research and development in Digital Domain, and his avatar.

3, spatial touch/audio: Apple "patted" your head and made you turn around.

In terms of enhancing spatial tactile perception, AR glasses will shift users’ attention to virtual phone conference or other places through tactile guidance. For example, users wearing AR glasses can feel that the pattern in front of them is moving to the left, and prompt users to turn to the left by vibration.

▲ FaceTime has updated the functions related to spatial audio.

Similar to the guidance mode of spatial touch, spatial audio mainly adjusts the sound change according to the user’s head change. This technology will monitor the head changes of users through image sensors, and also provide filters and visual guidance, so that users can have a better music experience.

At present, only AirPods Pro, AirPods Max and Xiaomi True Wireless Noise Reduction Headset 3 Pro support spatial audio applications, and there are not many other products that support spatial audio functions.

4, AR knows people/cars: specially built for Didi? Never have to worry about getting on the wrong bus again.

During the rush hour, there are often many network cars waiting for their customers on the roadside, but because of the large number of vehicles, customers are often prone to get on the wrong bus. In response to this situation, Apple’s new patent has created an AR system. When you wear AR glasses, you may be able to find your own network car at a glance from many vehicles.

The system will join hands with the online car software and provide two-way AR identification service, that is, drivers can find their customers in the crowd in time, and customers can also find their online car in the car sea in time. Since Apple invested one billion dollars in Didi Chuxing in 2016, and according to public information, Apple did not invest in other taxi software, therefore, this AR system may be specially built for Didi.

▲ Frame diagram of augmented reality system for proximity sensing.

The system can capture images through the camera of the mobile device, identify the corresponding vehicles and passengers with indicators or identifiers, and display them on the device. By simply displaying the signs, you will avoid the embarrassment of getting on the wrong bus during the rush hour.

What kind of experience will Apple’s AR glasses bring to people, and can they really help consumers in their daily lives? As the next generation of smart wearable devices, AR glasses play an important role in displaying information in the digital world for consumers, which can accelerate the combination of information in the digital world and the physical world. However, AR glasses on the market still have some shortcomings in data transmission and information display.

According to patent documents, Apple is giving new solutions to these problems through point cloud and virtual information display technology.

1. Overcome the data problem and speed up the data through point cloud compression.

Point cloud mainly refers to the data set of the midpoint in space, and usually 3d scanner obtains the relevant data of three-dimensional objects. Apple’s LiDAR lidar scanner on the iPhone 12 Pro series can support data collection and transmission of point clouds.

The new patent report indicates that "point cloud compression" can be formed by lidar scanner, providing more information for reality.

This technology can be used in VR, AR, geographic information system serving maps, sports replay broadcasting, museum display, autonomous navigation of Project Titan and many other projects.

2. The gospel of the road-crazy party: displaying virtual guidance information in the real environment.

In September this year, Apple obtained a patent related to displaying virtual information in a real environment, which allows users to locate and navigate to their destinations through mobile devices.

At present, the information service in the AR field usually needs to be completed by different technology combinations, and it is impossible to update the information in time according to the changes of the scene. In addition, some conventional GPS display technologies often cannot provide accurate location information.

The new system will display at least one piece of virtual information according to the real scene data, and will also display remote virtual information with low accuracy.

▲ Display the patent schematic diagram of virtual guidance information in real environment.

Specifically, when the user is close to the target area, the relevant information of other irrelevant areas will gradually disappear or be roughly displayed, and the digital information in the target area will be more detailed. Not only that, as people get closer to the target area, the relevant data will be more accurate.

To create a product that can cause a new consumption storm, we need not only technical support, but also innovative and creative talents as a strong backing.

As one of the first players in AR layout, Apple has an AR research team of nearly 1,000 people. According to Bloomberg News, the executive in charge of Apple’s AR business is Mike Rockwell, and his superior is Dan Riccio, Apple’s senior vice president of hardware engineering.

Mike Rockwell, a former executive vice president of Dolby and a senior researcher at Dolby Labs, is now one of the "candidates" for Apple’s next CEO.

▲ Mike Rockwell (Source: Patently Apple)

The team also includes new employees involved in video games, audio guidance, computer vision and special effects, as well as old Apple employees with rich experience in supply chain and program management. For example, Fletcher Rothkopf, who was in charge of watch design at Apple, and Tomlinson Holman, who created the sound standard THX.

In recent years, Apple has successively recruited talents from all over the world to expand its own AR R&D team. Previously, Apple had poached Li Zeyu from Magic Leap to be its own advanced computer vision algorithm engineer.

Not only that, Cody WHite, the former chief engineer of Amazon’s Lumberyard virtual reality platform, and Avi Bar Zeev, who worked in Hololens and Google Earth, have joined Apple’s VR/AR research team one after another, but interestingly, these two experts have left their jobs for reasons that have not been disclosed.

In addition to the talent pool, Apple has also strengthened its technical pool by acquiring a number of companies.

After Apple acquired Israeli hardware company PrimeSense in 2013, Apple successively acquired more than ten companies related to the AR field, involving sensors, AR software, AR content ecology and even AR lenses.

▲ Apple’s acquisition of company information related to AR glasses over the years.

To sum up, Apple has made a good talent reserve and technical reserve in the AR project. Now, everything is ready, except for the formal product launch and the test of the market.

Although Apple’s AR glasses have not yet officially appeared, Apple has already made many attempts in the AR field, not only bringing ARKit 5 system platform to the 2021WWDC conference, but also launching many AR-related functions such as Object Project and RealityKit 2.

Apple said that at present, 7,000 developers have developed 10,000 iOS apps that support AR. During the epidemic, people can purchase goods or complete home decoration through related AR software.

Not only developers can create their own products on ARKit platform, but also some amateur AR enthusiasts can DIY their own AR software on ARKit development platform.

In addition, the Apple TV+launched by Apple at this autumn conference may also become an important source of its future content ecology.

Although Apple has not launched its own AR software store, its AR content ecology and platform planning can gradually take shape, which will become one of the outstanding advantages of Apple AR glasses.

Strong technical library support, excellent R&D team and technical personnel, and rich content ecology, it seems that Apple AR glasses have occupied many advantages before the release, but for a consumer-grade product, performance is the standard to test everything, and it is also the most important grasp of the product.

In terms of chips, according to The Information, the chip design of Apple AR glasses has been completed, and now it has entered the trial production stage.

According to the report, the chip uses TSMC’s 5nm process technology, with CPU and GPU, but no neural engine belonging to Apple. It is reported that Apple’s chip may be connected to some host devices through wireless communication, and the host will bear the computing power.

Not only that, according to industry news, the CMOS image sensor version of this SoC is extremely large, and its size is close to that of a head-mounted lens. This may be to capture high-resolution image data from the user’s surrounding environment faster and provide better scene rendering or other AR services.

In addition, Apple’s AR glasses may be more lightweight and split-type, and Bloomberg has also said that Apple will produce a special version of Jobs. Major designers in the industry have also used their brains to "help" Apple design new AR glasses.

Korean designer Martin Hajek designed the concept map of the new AR glasses with reference to the dial of Apple Watch and the color matching of iPhone.

▲ The appearance of Apple AR glasses designed by Korean designer Martin Hajek

Judging from the design released by Martin Hajek, a three-dimensional artist in the Netherlands, Apple AR glasses may be similar to ordinary glasses. He used metal material in the frame, and placed a wireless antenna and sensor inside, with WiFi and Bluetooth parts on both sides of the frame.

▲ The appearance of Apple AR glasses designed by Dutch artist Martin Hajek

On the display side, Guo Ming said that Apple’s AR glasses may use OLED screens. Since Apple has previously acquired a company related to AR lenses, it is very likely that Apple will develop its own AR glasses.

In terms of whole machine OEM, Goer is currently the world’s leading OEM player of high-end AR/VR equipment, and once worked for Sony and Facebook. According to industry forecast, the AR/VR equipment assembly of Goer shares will account for 80% of the global market in 2021. Since Goer has also OEM AirPods and other related products for Apple before, based on its long-term cooperative relationship with Apple, the OEM of Apple’s AR glasses may be undertaken by Goer.

We can see that Apple has invested a lot in technology, talents and funds for its own AR glasses, and also tried to bring some new ways to play the display technology.

The concept of AR glasses has been around for a long time, but no mature products have appeared. For example, although Microsoft and Google have released some smart glasses products, they have not been widely recognized by users. Steven Law Corasa, head of AR at Adobe, once said that "Head Display, AR and other technical products are in our roadmap, but none of them have reached the critical quality that we can deploy."

The release of Apple’s AR glasses has become a major event of concern to the whole industry. Every time Apple’s press conference, we see that everyone pays close attention to Apple’s AR glasses. According to the industrial chain news, Apple will launch this AR glasses around 2023. Whether the upcoming products can cause other software, hardware and content eco-players to join the AR market, we will continue to pay attention to the latest trends.

Original attention to cutting-edge technology qubits is included in the topic # Huami 1# Chip 4# The technology circle is paying attention to 70.

Yang Jing is from Hefei

Quantum bit report | WeChat official account QbitAI

If it weren’t for being in Hefei, I would have thought it was a release conference of a song by a certain Vida.

At the beginning, the CEO came straight up with a huge wafer.

This big disc is engraved with 4000 chips made by ourselves.

In the next hour, it was even more confusing. Four shots were fired in succession, and the technique was very vertical.

There are chips, operating systems, AI algorithms, and MRI nuclear magnetic resonance equipment.

If I want to say again, this is a press conference of watch factory, I don’t believe it myself.

The conference of "Watch Factory"?

As you may have guessed, it is Huami, a watch factory headquartered in Hefei.

It made its debut in mi band, and then became the fastest-growing wearable manufacturer representative in NYSE with its endless product strength.

Chip has become the traditional artistic ability of Huami. In 2018, Huami bet on RISC-V architecture and launched the first AI chip in the field of smart wearable in the world-Huangshan No.1, which was mass-produced in the following year. Last year, at Huami’s first non-product conference, Huangshan No.2 chip was unveiled.

As the first launch of this conference, Huangshan 2S chip is called 2S, but it is not a simple improvement of the second generation.

It adopts dual-core RISC-V architecture. Among them, the large-core system can perform high-load calculations such as graphics and UI operations, and also integrates FPU to support floating-point operations. The small core, on the other hand, has low power consumption, and can process sensor data for 24 hours to realize continuous monitoring of biological data all day.

Large core and small core, clear division of labor, achieving a balance between computing power and power consumption.

Compared with the previous generation chip, the computing efficiency of Huangshan 2S is improved by 18%, the running power consumption is reduced by 56%, and the sleep power consumption is reduced by 93%.

Three years, three chips, realize the transition from usable to easy to use. The core-making project of Huami has entered the fast lane.

In addition to the chip, there is Zeppos, the native smart watch operating system that debuted.

As another field that is difficult to overcome in the intelligent hardware industry, the reason why Huami has to do it is also because of user demand and market drive.

There are two mainstream operating systems on the market at present. Either it is based on the mobile phone system magic change, but it is too cumbersome and complicated for wearable devices.

Either it is a ready-made embedded real-time operating system, which is more suitable for industrial control equipment and ordinary IoT products. It is directly used in smart watches that pay attention to experience, and some of them are not acclimatized.

Therefore, if Huami wants to do OS, there are two requirements first: lightness and user experience.

In terms of memory, the bottom layer of Zepp OS system is based on FreeRTOS micro-kernel open source code, which takes up very little space, and the system package is only 55MB, which is about 1/28 of Apple watch OS.

In terms of battery life, the running power consumption of Zepp OS is 65% lower than that of the previous Amazfit OS, thus ensuring continuous health data monitoring for 7×24 hours.

For developers, Zepp OS is also equipped with a watch applet framework-Zeus mini-program framework, which is convenient for developers to develop applets with a lower threshold.

In addition, the system also integrates 150 dials, including 15 dynamic dials. According to reports, the graphical development environment will be opened in the future, and individual users can also participate in the dial design.

In addition to the appearance of software and hardware, there is a brand-new AI algorithm-Pump Beats blood pressure monitoring engine. As a function with the highest voice in the whole conference, it can directly solve the current needs.

The smart watch equipped with this engine can measure blood pressure with one button in 30s. At present, Huami has started clinical experiments with the First Hospital of Peking University, and it is expected to be available in the fourth quarter.

According to the Report on Cardiovascular Health and Disease in China in 2020, there are as many as 245 million patients with hypertension in China, of which the adult prevalence rate is 23.2%. In recent years, the number of deaths related to hypertension is as high as 2 million every year.

After more than five years of research by Huami team, this engine has taken an important step in the field of non-invasive and sleeveless blood pressure measurement technology.

At the end of the conference, it also showed the latest medical field exploration promoted by Huami through investment-portable MRI (nuclear magnetic resonance) equipment, which corresponds to medical pain points.

Traditional medical MRI is a huge thing with high cost and high environmental requirements, and it is often hard to find a machine, so patients need to make an appointment a long time in advance.

Portable MRI not only occupies a small area, but also does not need a special shielding room. Compared with traditional high-magnetic MRI, portable MRI can achieve high-quality imaging at low field strength even when the signal-to-noise ratio is 300 times different.

Regardless of Huangshan 2S chip, Zepp OS, PumpBeats blood pressure monitoring engine and portable MRI (nuclear magnetic resonance) equipment, Huami’s various release actions have shown that the core of the enterprise adheres to: global self-research.

How did Huami embark on this road?

As early as 2015, Huami layout chips began to have a fixed number, but now with the maturity of technology, this road has gradually become clear.

Simple eight-word summary: global self-research and pursuit of the ultimate.

Chip is the extreme of hardware, operating system is the extreme of software, and the pursuit of AI system is the extreme of algorithm.

With the appearance of the operating system, Huami has opened up a global self-research from chips, algorithms to operating systems.

In fact, this path of self-research from chips, OS and algorithms is not unfamiliar. For example, Apple and Huawei.

Apple built S5 and S6 chips and Watch OS for Apple Watch.

Huawei has Kirin A1 chip and the newly launched HarmonyOS system.

The advantages of doing so are obvious. Combine software and hardware, and use your own chip to adapt to your own software ecology.

Manufacturers have great autonomy, no invisible constraints, and can customize product functions to form their own product strength.

In recent years, Huami has applied for more than 1,000 patents, of which invention patents account for half.

The ultimate in technology means the growth of R&D investment in Huami.

In the last three years, Huami’s average R&D investment has reached 410 million yuan every year. In 2020, R&D investment will reach 538 million yuan.

This kind of investment is equivalent to 2 times or even 3 times that of some emerging Internet companies and IoT intelligent hardware companies.

With such a big investment and pursuing the ultimate in technology, what does Huami think?

Considerations behind global self-research

First of all, the so-called knowing people and discussing the world is closely related to the development stage of the industry.

The first stage, let’s call it the mode verification period.

Back in 2013, Samsung released its first smart watch, Galaxy Gear, and officially entered the wearable field.

However, due to poor performance, it has been criticized a lot, so there is not much spray.

In the second year, Huawei, Apple and Xiaomi collectively entered the market, which really set off a wave of smart wear in China.

At the beginning of 2014, Huawei released the smart bracelet TalkBand B1 at the Mobile World Congress, which started the first shot.

In September, Apple released the Apple Watch, and then kept the frequency one more time a year.

It was also this year that Huami and Xiaomi joined hands and became an explosion through a cost-effective smart bracelet.

Huami also became famous in World War I and established its status as a river and lake.

Prior to this, the prospect of smart wearable was still in doubt. But when the explosion comes out, there is no doubt about the business prospects.

From 2015 to 2020, the market size of smart wearable devices industry in China increased from 11.48 billion yuan to 63.22 billion yuan, with a compound annual growth rate of 40.7%.

More importantly, smart wearable is widely regarded as the next growth point in the field of consumer electronics after mobile phones.

So the second stage-short and fast replication period-also came.

Now that the smart wearable Qian Jing and its prospects have been verified, and as a new growth point of consumer electronics, it is inevitable that new players will flood in and giants will copy quickly.

Smart wearable copying is actually simple and direct, and the advantages are obvious-you can take the volume quickly, you can make large-scale profits after taking the volume, and you can still make quick money.

However, shortcomings or hidden concerns are naturally obvious.

Low prices are cool for a while, but who is still alive by low prices in the field of mobile phones? The doctrine of taking is very easy to use. Isn’t the risk of getting stuck in the neck and cutting off the confession direct enough? Finally, following the trend of homogenization, you can only live in the shadow of "cottage" forever.

Therefore, for smart wearable manufacturers, or consumer electronics companies, there are opportunities to stand out from the crowd during the pattern verification period and the short and fast replication period.

But if we want to operate sustainably, make it bigger, deeper and longer-term, we must build our own moat.

For example, Amazon and JD.COM in the e-commerce industry also had their previous growth periods, but later decided that their ability to go deeper and further was self-built logistics of "humiliation and burden-bearing".

Self-built logistics undoubtedly requires a large investment, and it will also focus on the whole company and business, which runs counter to the "light assets" advocated by technology Internet companies.

However, it is self-built logistics that has become the guarantee for Amazon and JD.COM to build a long-lasting business and provide better and longer-tail services.

It has become a moat that truly enables enterprises to operate sustainably.

For the current smart wearable industry, for Huami, isn’t the global self-developed chip and system just "self-built logistics"? Isn’t it to build a moat for the long term?

In fact, if we return to the company’s goals, especially the pressure of regular financial reports faced by listed companies, it may not be an easy way to do research on the whole stack.

However, even under such pressure, Huami still chose the self-developed system and chip, and insisted on the difficult and correct road, which shows its ambition and its long-term ambition.

On the other hand, from the perspective of users and consumers, a consumer electronics company that has proved that its actions will continue to provide long-term value is a company that will be trusted.

Nowadays, Huami is naturally a vertical champion in the wearable field, but don’t ignore that the global giants like Apple are racing together on this track.

Competing with a company like Apple can only run like water. It’s not a matter of time, but a matter of time.

Only by going deep into chips and systems can we have the qualification and ability to talk endlessly.

From this perspective, the road of Huami is no longer difficult to see through.

How to evaluate the way of huami?

Look back at Hua Mi’s movements.

From a technical point of view, Huami has done more and more "deep", from chips and systems to consumer brands. Nowadays, in addition to Amazfit, there are Zepp, and there are related OEM businesses upstream.

Forming a closed-loop technology will certainly highlight the product strength of Huami more and more, enhance the brand effect and expand the benefits.

Does that mean that Huami has to take a closed road?

On the surface, it is, but it is not.

On the one hand, based on the current business needs, Huami needs to open its products to the outside world after reaching a certain level.

At the press conference, Huang Wang announced that he would open the chip and operating system to third parties through Yitong Technology.

The products pass the stage of practical verification, providing solid evidence for Huami technology, which is conducive to building brand trust in the industry and more conducive to the healthy development of the whole industry.

On the other hand, from the perspective of the industry, global self-research represents Huami’s determination to deepen the health field.

As mentioned before, with the intensification of industry competition, other competing products are caught in the whirlpool of low-price competition, system takenism, homogenization function, etc., but there is still more potential hidden behind the fog in the field of healthy wear, which has not yet been developed, which requires industry entrants to concentrate on exploring more integration points between technology and human needs.

In this matter, Huami will go her own way.

This can explain why Huami is not only self-researched, but also hopes that some IoT partners such as smart door locks, smart cars and sweeping robots will participate, and finally connect the whole ecology through opening ports. In fact, the Zepp OS operating system of Huami’s conference can support the entire RISC-V ecosystem.

To some extent, smart wearable is just a representation, and the value of Huami lies in pushing the health industry forward.

Numerous industry stories in the past have long shown that if an industry or field wants to develop healthily, it is far from enough to rely only on cross-border systems and marketing methods. What will wearable health equipment look like for you and me in the future?

Need Huami, and even more enterprises to explore the possibilities of the industry to participate.
