Extended range car： an innovative journey from germination to popularity

The development of automobiles.

In today’s era of continuous change and innovation in the automobile industry, automobiles, as a unique type, are gradually emerging in the market. It not only has the advantages of environmental protection, but also overcomes the endurance anxiety of pure electric vehicles to a certain extent, which has become the focus of many consumers and automobile manufacturers. Let’s review the development of automobile together and explore its trajectory from birth to gradual rise.

First, the origin of the car. The concept of automobile can be traced back to the early 20th century, when it was in a stage of rapid development, and people put forward higher requirements for the performance and reliability of automobiles. Some engineers began to think about how to improve the fuel economy and environmental protection of automobiles without sacrificing performance, so the new concept came into being.

Early cars mainly added a battery pack on the basis of traditional fuel vehicles, which were driven by electric motors and mainly used to charge batteries. Although this design concept has improved the fuel economy of the automobile to a certain extent, it has not been widely used because the battery technology and motor technology at that time were not mature enough and the performance and reliability of the automobile were not ideal.

Second, the tortuous road of technological development. In the following decades, the development of automobile experienced a long and tortuous road. With the outbreak and the continuous improvement of environmental awareness, people’s demand for new energy vehicles is increasing. However, due to technical and cost constraints, pure electric vehicles and hybrid electric vehicles can not fully meet the market demand for a long time.

During this period, some car manufacturers began to pay attention to cars again and invested a lot of resources in research and development. By constantly improving battery technology, motor technology and engine technology, they have improved the performance and reliability of automobiles. At the same time, the government has also issued a series of policies to support the development of new energy vehicles, providing a good policy environment for the development of automobiles.

Nevertheless, the performance of cars in the market is still unsatisfactory. On the one hand, due to the relatively complex structure and high cost, it is difficult to compete with traditional fuel vehicles and pure electric vehicles. On the other hand, consumers’ awareness and acceptance of cars are relatively low, and many people have doubts about the performance and reliability of this new type of car.

Third, the rise in recent years. Since the 21st century, with the rapid development of battery technology, motor technology and electronic control technology, automobiles have ushered in new development opportunities. Some emerging automobile manufacturers began to take automobiles as their main product direction, and launched a series of competitive models.

Take it as an example, its ideal L series models have achieved great success in the market. These models adopt advanced extended range technology, and the comprehensive cruising range can reach thousands of kilometers, effectively solving the problem of users’ endurance anxiety. At the same time, they also have spacious and comfortable interior space, rich intelligent configuration and excellent dynamic performance, which are favored by many consumers.

In addition to LI, the car series, such as car, also performed well in the market. The appearance of these models not only enriches the product line of automobiles, but also improves consumers’ awareness and acceptance of automobiles.

Fourth, the technical characteristics of the car. The core technology of automobile is range extender, which is usually composed of engine, motor and motor. The function of the range extender is to charge the battery when the battery is low and extend the cruising range of the vehicle. Different from the traditional fuel car, the engine of the car does not directly drive the car, but converts mechanical energy into electrical energy through the generator, and then the electric energy is converted into mechanical energy by the motor to drive the car.

This design concept makes the car have the following technical characteristics:

→1. Long cruising range: Due to the existence of the range extender, the car can charge the battery when the battery power is insufficient, thus extending the cruising range of the car. Compared with pure electric vehicles, cars have a longer cruising range and are more suitable for long-distance travel.

→2. High fuel economy: under urban working conditions, cars can mainly rely on battery to achieve zero emissions; When driving for a long distance, the range extender can work in the most economical condition to charge the battery and reduce fuel consumption.

→3. Good driving experience: Cars are usually driven by electric motors. The characteristics of the electric motors make the vehicle have a quick dynamic response and a smooth acceleration when starting, and there is no sense of shift frustration of traditional fuel vehicles.

→4. Good environmental protection performance: Although the car needs to consume fuel during use, its engine is mainly used to charge the battery instead of directly driving the vehicle, so its emission is relatively low and its environmental protection performance is better.

V. Future development prospects. With the continuous progress of technology and the continuous reduction of cost, the future development prospect of automobiles is very broad. On the one hand, with the continuous development of battery technology, the energy density and cruising range of batteries will be continuously improved, which will further improve the performance and competitiveness of automobiles.

On the other hand, as the government’s support for new energy vehicles continues to increase, cars will be expected to get more preferential policies and subsidies to reduce consumers’ car purchase costs. In addition, with the increasing awareness and acceptance of new energy vehicles by consumers, the market demand for automobiles will also increase. In the future, automobiles are expected to become an important part of the new energy automobile market and contribute to promoting the automobile industry.

In a word, automobile, as a new type of new energy vehicle, has experienced some twists and turns in its development process, but it has gradually risen in recent years and shown great development potential. It is believed that in the future, with the continuous progress of technology and the continuous maturity of the market, automobiles will play a more important role in the automobile industry.

During the year, 182 ＂recyclable transfer stations＂ and ＂bottom recycling＂ waste glass waste foam boxes will be built, and worthless waste products will also be collected at home.

　　Original title: During the year, 182 "recyclable transfer stations" will be built, and worthless waste products from "bottom recycling" waste glass waste foam boxes will also be collected at home.

　　Some people collect "valuable waste products" such as cardboard boxes, plastic beverage bottles and scrap metal, but "worthless" waste products such as glass bottles, old clothes and foam boxes are obviously recyclable, but no one who collects waste products is willing to recycle them. According to the Municipal Urban Management Committee, before the end of the year, 182 "recyclables transfer stations" will be built in this city, the main task of which is to recycle and treat "low-value recyclables" such as waste glass, waste textiles, waste foam boxes and large garbage, so as to play the role of "bottoming recycling". This means that "low-value" waste products will soon be sold.

　　In Hualong Meiyu Community, the "waste recycling" personnel appointed by residents to manage the country on behalf of the country came to the door. Old cartons, wrapping paper holders, plastic bags for quilts, foam boxes for fresh food, glass bottles … The waste recycling staff sorted the waste that had been saved for more than a month on behalf of the country, and took out electronic scales to weigh it. After weighing and measuring all the waste products, the waste recycler indicated that he would take out his mobile phone on behalf of the country. "A total of 16 yuan, I will transfer money directly to WeChat."

　　Like this "paid recycling of waste products", 19 communities in Baizhifang area have achieved full coverage. Zhang Xiaobo, director of the Urban Management Office of Baizhifang Sub-district Office in Xicheng District, said that each community in Baizhifang has set up a garbage sorting station, which can recycle waste products with compensation. In addition, 13 fixed recycling points have been built, and 7 mobile recycling vehicles are equipped. If residents don’t want to go to the recycling point to trade waste products, they can also make an appointment for a recycler to collect them at home, just like managing the country on behalf of others.

　　"In many societies, only cardboard boxes, plastic beverage bottles and other recyclables with high recycling value are collected. In addition to recycling valuable waste products, we also recycle worthless waste products such as foam boxes, beer bottles and old clothes. " Yin Bo, director of the operation office of Beijing Jincheng Xinheng Renewable Resources Utilization Co., Ltd., said that the collected domestic garbage can not only be accumulated, but also be transferred by cash via WeChat and Alipay to meet the needs of different residents.

　　"In the next step, we also plan to introduce garbage classification points to deduct some property fees, and kitchen waste, other garbage and recyclables can participate in the points." Zhang Xiaobo said.

　　Soon, all the recyclable garbage in the city will be collected and disposed of. Wu Runjiang, a third-level researcher at the Solid Waste Department of the Municipal Urban Management Committee, said that in 2021, the city will build another 600 "domestic waste sorting stations". "At present, 339 buildings have been built in each district. In the next step, those that meet the standard requirements will be verified and accepted, and those that do not meet the standard requirements will be rectified. "

　　In addition, the city will also build a "recyclable transfer station". Wu Runjiang said that 182 buildings will be built by the end of the year, and now 151 have been built. The main task of the transfer station is to recycle and treat "low-value recyclables" such as waste glass, waste textiles, waste foam boxes, and large-sized garbage, and play the role of "bottoming out".

　　At present, the city has built two sorting centers for renewable resources, located in Chaoyang and Miyun respectively. Three temporary sorting centers have been put into trial operation, located in Daxing and Yanqing respectively.

　　Wu Runjiang said that in the next step, the city will start with low-value recyclables, introduce corresponding policies and measures, such as giving some necessary subsidies to low-value recyclables, and guide enterprises to promote the classification of recyclables by means of door-to-door recycling, so as to achieve all points and all receivables.

Difference between Ferrari sf90spider and sf90

SF90 Spider is the latest model of Ferrari. It is a roadster. The SF90 is a plug-in hybrid sports car of Ferrari, which is Ferrari’s first mass-produced V8 hybrid supercar.

The main difference between the two is that:

1. The power system is different: SF90 adopts plug-in hybrid power system, which consists of a 4.0-liter V8 engine and three motors; The SF90 Spider uses the traditional naturally aspirated V8 engine, and has no motor configuration.

2. Different appearance: SF90 Spider is a convertible design, and the roof can be folded up at high speed; The SF90 is a hard top design.

3. The performance parameters are slightly different: due to the different power systems, their performances in acceleration and extreme speed are also different. But overall, the performance of both models is excellent.

Compulsory internships that earn ＂headcount fees＂ must be curbed.

　　[Guangming Times Review]

　　Author: Xiong Bingqi (Dean of 21st Century Education Research Institute)

　　Recently, the Ministry of Education and other departments jointly issued the newly revised Regulations on the Management of Students’ Internship in Vocational Schools (hereinafter referred to as the Regulations), clarifying that "internships should not be arranged across major categories", "students should not be arranged to engage in simple repetitive work", "students should not be arranged to engage in manual labor of Grade III intensity or above or other internships harmful to physical and mental health" and "it is strictly forbidden to organize internships illegally for profit".

　　As early as 2016, the Ministry of Education, the Ministry of Finance and other five departments jointly issued the Regulations on the Management of Students’ Internship in Vocational Schools, which played an important role in regulating students’ internship in vocational schools. However, in recent years, there are still some problems in some areas, such as organizing students to work in the production line of enterprises in the name of internship, arranging overtime and night shift, compulsory internship, fee-based internship, and mismatch of internship majors.

　　The compulsory practice of earning "headcount fee" is nominally "school-enterprise cooperation", and the essence is to treat students as cheap labor. Schools charge management fees by exporting labor services to enterprises, while enterprises fill the labor shortage with student labor services. Most of the enterprises that vocational colleges force students to practice are low-end labor-intensive enterprises. It is difficult for these enterprises to recruit workers through the labor market and turn to schools for "cooperation" to obtain cheap labor. Students are arranged to do assembly line repetitive work unrelated to their majors, which not only infringes on students’ rights, but also misleads students’ understanding of vocational education and skilled personnel. Many students have not learned skills and think that skilled personnel have no way out. The existence of this kind of low-end practice actually hinders the improvement of vocational education quality and affects the image of vocational education.

　　The revised "Regulations" focus on curbing the compulsory practice of earning "headcount fee", protecting students’ legal rights and improving the quality of practice. To implement the Regulations, in addition to improving the accountability mechanism, we must seriously blame the off-campus vocational colleges that illegally organize internships, we must also strengthen investment in vocational colleges, eliminate backward enterprises that have been unable to recruit laborers from the labor market, and promote the establishment of a modern vocational college system to carry out high-quality integration of production and education.

　　For the illegal organization of student internships in vocational colleges, most of the current treatments are just to stop illegal internships, without further treatment and accountability. In this regard, we should increase the punishment, blacklist the schools that illegally organize students’ internships, disclose the school’s illegal behaviors to the public, reduce its enrollment plan or even revoke its qualifications for running schools.

　　In addition to the relevant personnel profiting from it, there are also vocational colleges that illegally organize student internships as a way to obtain school funds and improve teachers’ treatment. In recent years, some intermediaries have also seen this demand in vocational colleges and intervened to organize student internships as business opportunities. Regarding the participation of intermediary agencies in students’ internships, the Regulations specify that the tripartite agreement on internships must be signed by vocational schools, internship units and students, and reiterate that students’ internships cannot be organized, arranged and managed through intermediaries or paid agents. The warning significance of this is that institutions that enter the field of vocational education can’t make profits and take organizing student internships as a business. The school’s self-"labor intermediation" is more worthy of attention. In this regard, it is necessary to increase investment in vocational colleges, improve the treatment of vocational school teachers, and let schools concentrate on running schools.

　　Practice is an important link in the practical teaching of vocational school students, which is not only a necessary way for professional learning and technical skills training, but also an important way to temper the will quality, get familiar with the post in advance and guide integration into society. In order to achieve the goal of practice teaching, it is necessary to eliminate the practice of working in the post.

　　In the final analysis, organizing students’ internships in vocational colleges is an educational matter. To avoid vocational schools sending students to work in enterprises that do not have internship conditions, it is necessary to play the role of the school professors’ committee, which makes internship teaching plans, selects qualified internship enterprises, designs internship teaching contents, supervises the internship teaching process and evaluates the internship teaching effect. This is the key to establish a modern vocational college system and to improve the quality of running a vocational college.

　　Guangming Daily (January 27, 2022, 02 edition)

China is the country with the largest amount of marine plastics. How can plastic waste be discharged into ocean currents？

Several ways for plastic garbage to enter the ocean;

1. Dump directly into it. For some plastic wastes with no recycling value, in order to reduce the cost, they are either directly burned or dumped into rivers and finally merged into the ocean. This phenomenon is particularly common in rural areas of China, and at present, the treatment capacity of landfill sites in China is mostly saturated, and there is no matching treatment capacity with a large number of plastic wastes. In addition, some of them are daily garbage produced by human life, which are randomly discarded in rivers, beaches and the sea due to the incomplete recycling system and the lack of environmental awareness. The widespread use of disposable plastic packaging aggravates this situation, and the related garbage collection system may be underdeveloped or even non-existent.

2. Sewage outlet. Mainly discharged into rivers through sewage pipes of sewage treatment plants. The waste water of industrial products may contain plastic particles, and in some places where supervision is not strict, large pieces of plastic waste may be directly discharged with the waste water through the sewage outlet.

3. Secondary pollution caused by improper garbage disposal

(1) landfill leachate pollution caused by improper landfill. The plastic particles contained in these leachate will penetrate deep into the soil and pollute the groundwater. The groundwater and the water flow in inland lakes are complementary, and these polluted groundwater will enter the river through the lake and finally flow into the ocean.

(2) Non-standard treatment of plastic recycling family workshops in China. In these small workshops, it is often necessary to use a lot of clean water to clean plastic waste, and these plastic-washed wastewater will not be treated harmlessly, so it will directly carry a large number of plastic particles or even whole pieces of plastic into the river. Like these sewage, the remaining plastic garbage residues will be directly dumped on the river bed.

4. Maritime activities

Including marine aquaculture and fishing, exploration and development, all kinds of garbage and ship coatings discharged during the ship’s driving. Some large-scale maritime accidents, such as capsizing of ships and leakage of raw materials, will also lead to plastic waste entering the boundless sea.

What impact will plastic waste have on the ocean?

People call the plastic garbage floating on the ocean the "seventh continent" as a whole, and plastic pollution has become the "unbearable weight of life" for many marine creatures in the vast ocean.

The harm of plastics to wild animals is unimaginable to human beings.

Maybe you never thought that the plastic rope you threw away would sink into the sea and entangle with countless marine life. It is reported that at least 344 species have been caught in the pain of being entangled with plastic so far.Including all turtle species, more than two-thirds of seal species, one-third of whale species and one-quarter of seabirds.

The seemingly dazzling and exquisite packaging plastic paper is also "hidden" after flowing into the sea. Most marine life has eaten plastic fragments by mistake. According to the records of the media and related institutions,At least 233 marine species, including all turtle species, more than one-third of seal species, 59% of whale species, 59% of seabird species, 92 species of fish and 6 species of invertebrates, have ingested plastics..

In addition, touching or colliding with plastic products can also threaten the lives of marine animals. For example, fishing gear has been proved to cause wear and damage to coral reef ecosystem during collision.

The report "Marine Garbage: Understanding, Preventing and Mitigating the Adverse Effects on Marine and Coastal Biodiversity" issued by the Secretariat of the United Nations Convention on Biological Diversity collates the field investigation of polluted marine organisms since 2012. The report shows that plastic pollution has involved various marine biota such as fish, algae, marine birds, marine mammals and marine reptiles.

To make matters worse, plastics are encroaching on the habitats on which marine life depends at an alarming rate. UN Secretary-General Guterres pointed out that pollution, overfishing and the impact of climate change are seriously damaging the health of the oceans. He said that according to a recent study, by 2050, the total weight of plastic waste in the ocean may exceed that of fish.

▍Marine plastics are difficult to degrade.

Plastic is a synthetic macromolecular polymer, and its molecular structure is difficult to be destroyed by biodegradation. If plastic is to be completely degraded into small molecules, a large number of chemical bonds need to be completely broken. For polyethylene molecules, this requires a lot of energy. Therefore, it may take hundreds of years to completely degrade plastics. A BBC report mentioned that a plastic cup can "survive" on the earth for half a century, which shows that the degradation of plastics is very difficult. Unlike land, the refrigeration effect of seawater slows down the degradation process caused by sunlight and high temperature. Therefore, the process of comprehensive decomposition of marine plastic waste is more long and arduous.

-It is difficult to recycle marine plastics.

The vast majority of monomers used to make plastics, such as ethylene and propylene, come from fossil hydrocarbon maps. None of the commonly used plastics is biodegradable. Plastics will eventually accumulate in landfills or natural environments rather than decompose. The only way to permanently eliminate plastic waste is through destructive heat treatment, such as combustion or pyrolysis. Therefore, the near-permanent pollution of the natural environment with plastic waste is an increasingly serious problem. Plastic fragments have been found in all major ocean basins, and it is estimated that the plastic waste entering the marine environment in 2010 alone reached 4-12 million tons. Fresh water system and terrestrial ecological environment are increasingly eroded by plastics.

Nowadays, plastic waste is everywhere.

Sea water is flowing, and plastic will drift to all directions with the water flow; Seawater is also unfathomable, and plastics with different weights and qualities will be divided into different depths. No matter how hard people try, there is no guarantee that there will be no more plastic in the seawater of a certain area. When the plastic is turned into tiny particles, things become more complicated, the difficulty of recycling suddenly increases, and the harm is even greater.　

-There are limitations in monitoring marine plastics

1. There are disputes about the data model and sampling method of plastic waste.

A few days ago, a number of experts and scholars announced their monitoring results of microplastics off the coast of China at the APEC seminar on innovative ways to prevent and control marine debris. Although the monitoring scope is the same, their data results are quite different. Luo Yongming, a researcher from Yantai Coastal Zone Research Institute of Chinese Academy of Sciences, said that this is due to the differences in sampling tools and methodology.

Not only are there great differences in domestic research results, but the sampling and research methods of marine plastic waste have not been unified internationally. Li Daoji, a marine environmental expert, once pointed out that the international model research on the amount of marine plastic waste has not measured the amount of plastic waste discharged by various countries, and the research method is still open to question.

2. It is difficult to monitor and treat marine plastic waste.

It is very difficult to track the input and distribution of marine plastics, and there is a great difference between the annual input of plastics and the ocean and the estimated value of surface plastic accumulation. This difference is called the "missing plastic" problem. The monitoring of microplastics is even more difficult, because the particle size of microplastics is very small, and the analysis is very difficult. Therefore, the economic strength of different research teams, the ability to obtain data, the advanced analytical instruments and the feasibility of analytical technology will all have an impact on the monitoring results, which leads to great uncertainty in the monitoring of marine microplastics.

Therefore, it is unrealistic to try to clean up all the plastic garbage in the ocean by manpower. What human beings should do is how to reduce the production and use of plastics, improve the recycling and utilization rate of plastics, and control the source of pollution.

Tens of billions of years ago, the first single-celled life on the earth was born in the ocean, but there is no doubt that these white ghosts created by ourselves are slowly destroying the source of life. It is difficult for us to predict where the plastic bottles we throw away will float, just as we can’t predict what node these plastic wastes will bring to the fate of six billion human beings.

Boxster’s past lives. It brought Porsche back to life.

　　[History of car home Cars] Today, Porsche is one of the most profitable car manufacturers in the world. However, in the 1990s, it suffered a serious crisis and almost went bankrupt. How did Porsche get out of the predicament step by step and realize its legendary revival? Among them, (|), the two-seater roadster to be discussed in this paper, plays a decisive role.

Home of the car

　　In the early 1990s, although Porsche owned three models, 928, 911(964) and 968, the sales situation was not satisfactory, which caused the company to fall into a terrible business crisis. In order to save the enterprise, Porsche has carried out drastic reforms. On the one hand, Toyota production mode is introduced to save costs and improve production efficiency.

　　On the other hand, adjust the product range, stop production of the expensive 928 and 968 equipped with front-mounted 4-cylinder engine, and instead develop a sports car with more attractive price that can capture the hearts of young consumers. In addition, in order to raise more funds, Porsche and Audi jointly built a high-performance station wagon RS2 and designed a sedan C88 for the China market.

　　In 1991, Porsche, which was in deep crisis of survival, tried various solutions, including a two-seat convertible concept car with a mid-engine layout-Boxster. The design of the car was inspired by the concept car Panamericana built by Ferrari Porsche on his 80th birthday. The short rear suspension and short body, the front suspension extending forward and protruding from the front axle and the exhaust tailpipe arranged in the center of the rear of the car continue the classic design of Porsche.

　　Boxer is a combination of the words "horizontally opposed engine" and "roadster". This name contains the initial setting of horizontally opposed engine, which is also a prominent technical feature shared by the 356 models launched in 1948 and the 911 models from 1963 to the present. The concept of mid-engine is derived from the predecessors 550 Spyder, 914/6 and 718 racing cars.

　　Boxster concept car is equipped with Porsche’s first mass-produced water-cooled horizontally opposed six-cylinder engine, with an initial displacement of 2.5 liters and a maximum power of 204 HP. Because of the water cooling system, four valves and variable intake timing, its design meets more stringent emission standards. The car’s innovations also include a balanced weight distribution, a quick-opening movable roof, a braking system derived from racing, and the best drag coefficient (Cd=0.31) in its class.

　　The research and development work is in full swing. According to Grant Larson, the designer in charge of Boxster concept car, "We originally planned to show our concept car at the Geneva Motor Show in the spring of 1993. But we decided to choose Detroit in January because we didn’t want to waste any time. More importantly, our focus on sports cars was on the American market, when Porsche did not perform well in the American market. Mazda Miata and BMW Z1 have already appeared in the market. "

　　The Boxster concept car unveiled at Detroit Auto Show was very popular. "Boxster received overwhelming praise from the public and experts, which obviously had an impact on development," Grant Larson continued. "Shortly after the exhibition in Detroit, we were asked to stop the design and development of Boxster immediately, and instead, we were asked to produce it as a concept car!" Time has proved that this is a wise decision.

　　In October 1996, Porsche Boxster was officially released, which filled the gap of entry-level models below 911. It is worth mentioning that Boxster is not only manufactured in Zuwenhausen factory in Stuttgart, but also subcontracted to Valmet company in Finland, which is the first time that Porsche models have been produced outside Germany since the early Austrian factory.

Attention! This ＂subsidy＂ must not be received!

"Individual labor subsidy in the fourth quarter of 2023"

It has been distributed now.

Receive such an e-mail

Don’t get it yet!

This is a new trap for swindlers! !

Real case

Recently, Ms. Lou (Hua’s surname) of Chengxiang Street in Xiaoshan received an email entitled "Application for Personal Labor Subsidy in 2023" at home, which required "scanning the QR code registration information in the document and receiving the labor subsidy for on-the-job personnel." Ms. Lou didn’t think much, scanned the code and opened the link, and filled in personal information such as ID number and bank card number as prompted. However, when she filled in the verification code and payment password, she received a debit message from the bank, showing that the deduction was 6900 yuan, and she realized that she was cheated.

Routine analysis

Step 1: Send fake mail.

Liars illegally embezzle the mailboxes of internal managers of enterprises and send emails to employees in batches. The contents are official documents of relevant government departments on issuing "labor allowances and subsidies" with QR codes attached.

Step 2: Induce to fill in personal information.

The swindler induces the deceived person to scan the code and log in to the fraudulent website, click "Confirm Collection" on the page, and fill in personal information such as ID number, bank card number and bank card balance as prompted.

Step 3: Induce the input of verification code.

After the deceived person receives the short message of the bank’s verification code, he is induced to input information such as verification code and bank card password to steal the balance in the victim’s card.

1. If you receive an email similar to "scan the QR code to receive subsidies", check with the relevant departments of the company in time, and don’t believe it easily.

2. Don’t scan the unknown QR code at will, and protect personal information such as ID number, bank card number, balance and mobile phone verification code.

3. In case of online fraud, keep relevant evidence materials such as chat records and transaction records, and call 96110 in time.

The holding group will mainly assume the role of innovation incubation base camp.

　　At the same time, Zhang Yong announced that the complete spin-off of Alibaba Cloud Intelligent Group has started, and it is in the most critical period of upward development, so we must devote ourselves wholeheartedly. At the same time, in order to adapt to the future development norms and requirements, it is not appropriate for him to serve as chairman and CEO of the two companies at the same time. With the approval of the Board of Directors of Alibaba Holding Group, Zhang Yong will step down as Chairman and CEO of the Board of Directors of Alibaba Holding Group on September 10th this year. After that, Zhang Yong will be the full-time chairman and CEO of Alibaba Cloud Intelligent Group, focusing on the development of Alibaba Cloud, continuously enhancing Alibaba Cloud’s industrial competitiveness and global competitiveness, and allowing Alibaba Cloud to provide better, safe and convenient basic services for the digital intelligence upgrade of various industries, especially small and medium-sized enterprises.

Ali announced a coaching change: Zhang Yong will step down and they will take over.

　　On June 20th, Zhang Yong officially started the handover with Cai Chongxin and Wu Yongming.

　　This year is the sixteenth year that Zhang Yong has worked in Ali. Zhang Yong joined Ali as the CFO of Taobao in 2007, became the CEO of Alibaba Group in May 2015, and became the Chairman of the Board of Directors of Alibaba Group in September 2019. Since December last year, he also served as the president of Alibaba Cloud Intelligent, and was directly in charge of nailing.

　　Jack Ma, founder of Alibaba Group, spoke highly of Zhang Yong. In 2019, when Ma Yun stepped down as the chairman of Ali’s board of directors, he published an open letter, in which he wrote, "(Zhang Yong) has demonstrated outstanding business talent and firm and calm leadership since he became the CEO of Alibaba Group, and achieved healthy and sustained growth in Alibaba’s performance for 13 consecutive quarters."

　　"Alibaba’s relay torch was handed over to him and the team he led. I think this is the most correct decision I should make now. My cooperation and cooperation experience with Zhang Yong in recent years has made me full of confidence in him and the new generation of Alibaba leadership team he led! "

　　For the new successor, Zhang Yong also expressed his support in an open letter. He wrote, "Cai Chongxin (Joe C.
Tsai) will succeed me as Chairman of the Board of Directors of Alibaba Group, Eddie Yongming.
Wu) will succeed me as CEO of Alibaba Group. Both of them are founders and partners of Alibaba. They have made important contributions to the historical development of Alibaba Group and have rich experience. I believe that under their leadership, the company can move towards a more brilliant future. "

　　Cai Chongxin is Ma Yun’s most trusted entrepreneur and is currently the executive vice chairman of Ali Group. From the establishment of the company in 1999 to 2013, he served as CFO of the group, and in 2014 he led the company to go public in new york, and then he was responsible for strategic investment.

　　Wu Yongming has served as the chief technology officer of many important businesses such as B2B, Taobao and Alipay, and led the construction of the underlying technical architecture of related businesses. Led the creation of the group’s core business, Ali Mama Platform, and the innovation hatched the mobile phone Taobao, which promoted the wireless of the group.

　　More than two months ago, Alibaba announced the establishment of a "1+6+N" organizational structure, that is, under Alibaba Group, six business groups and a number of business companies were established, including Alibaba Cloud Intelligent, Taobao Tmall Business, Local Life, International Digital Business, Rookie and Big Entertainment.

　　According to the "listing timetable" of Alibaba Group’s sub-board, Alibaba Cloud will be split up and listed independently in the next 12 months, and Cainiao and Box Horse will be listed within one and a half years, and the international digital business group will start external financing.

　　It is worth noting that some media reported that in late May, Ma Yun called the business leaders of Taotian Group and held a small-scale communication meeting. Dai Shan, CEO of Taotian Group, Hai Wang (flower name: Qigong), Liu Peng (flower name: Aowen) and Liu Yiman (flower name: Yiman), the head of Taobao live broadcast, Cheng Daofang (flower name: Daofang) were present.

　　Ma Yun said at the meeting that the methodology that Ali used to rely on for success may no longer be applicable and should be quickly changed. He pointed out three directions for Taotian Group: returning to Taobao, returning to users and returning to the Internet. In addition, Ma Yun believes that Taotian should be further flattened in organization.

　　Attached:

　　Zhang Yong, Chairman and CEO of Alibaba Group, sent a full letter on June 20.

　　Dear Ali people,

　　Since I became the CEO of Alibaba Group in May 2015, I have always written several letters to you every year. Maybe everyone is used to it. When you see the letter I sent to all employees, you will know that there are important changes in the company. I wrote to you again today, which brought you an important change about myself.

　　Since the "1+6+N" organizational reform was announced in March this year, all the work is progressing smoothly and orderly. When the financial report was released last quarter, we announced the composition of the boards of directors of various business groups, and at present, all the boards of directors have started to operate. We also announced a number of plans for various business groups and business units, including the complete spin-off and listing of Cloud Intelligence Group from Ali Group, the listing of Cainiao Group and Box Horse, and the independent financing of overseas digital business groups. The whole Alibaba is heading for the future with a new attitude.

　　As we all know, the development of core technologies such as cloud computing, big data and artificial intelligence will bring great changes to society, which is of great strategic significance. At present, the complete spin-off of Cloud Intelligence Group has started, and it is at the most critical moment, which requires me to devote myself to it. At the same time, considering the requirements of standardized corporate governance during the spin-off, I personally should no longer be the chairman and CEO of both groups. Therefore, the board of directors of Alibaba Group discussed and accepted my request: from September 10, 2023, I will no longer serve as the chairman and CEO of Alibaba Group, but concentrate on doing the work of chairman and CEO of Alibaba Cloud Intelligent Group full-time. At the same time, the board of directors of Alibaba Group decided that Cai Chongxin (Joe
C. Tsai) will succeed me as the chairman of the board of directors of Alibaba Group, Eddie Yongming.
Wu) will succeed me as CEO of Alibaba Group. Both of them are founders and partners of Alibaba. They have made important contributions to the historical development of Alibaba Group and have rich experience. I believe that under their leadership, the company can move towards a more brilliant future.

　　This change is not only for the company, but also for me personally, which is the beginning of another new stage and a new journey. How time flies! This year is my sixteenth year in Ali. I have been traveling together for 16 years, especially since I took over as CEO of the Group in 2015 and Chairman of the Board of Directors of the Group in 2019. It is precisely because of your trust, support, encouragement and tolerance that I have devoted myself to this position that I never imagined. I am sincerely grateful and grateful to you. In the past 16 years, because of the opportunity of social progress and market development, I have the honor to witness the historical stage of Alibaba’s rapid development with you, and participated in many creations that have benefited ordinary people’s lives from scratch, from small to large, from the digital process of enterprises to the beautiful society; Together with all of you, we have withstood the challenges of COVID-19 epidemic in recent three years and various tests brought by external environmental changes. No matter in good times or bad times, we not only grew up together, experienced together and spent together, but also gained a lot of friendship and friendship more valuable than our career.

　　In the past 24 years, we have had many such moments of self-change. Now, we all stand at a new starting point together and start a new stage of future development through self-transformation. I believe that everyone will support the work of Joe and Wu Yongming and other senior students in the new group. Everyone can find their own stage and their own career, and finally contribute to society, achieve the company and achieve themselves. I will also stand on a brand-new stage with the students of Cloud Intelligence, and explore the new technologies of cloud computing, big data and artificial intelligence to serve the huge prospect of digitalization and intelligence in thousands of industries. I am full of longing and expectation for this.

　　Castle peak will not change, green water will flow forever, create a new river and lake, meet again, and be happy!

8.7 points, 19 bans, how exciting is this crime Korean drama？

The writer of this article is writer @ Luo Baikou.

A popcorn at the cinema

In 2017, Incheon, South Korea.

A 17-year-old girl abducted an 8-year-old girl and brutally killed and dismembered her.

At first, the police diagnosed the murderer as a schizophrenic. However, as the premeditated murder plan surfaced, she was finally judged as a psychopathic murderer and deserved a heavier sentence.

This case caused an uproar in South Korea because of its bad nature, cruel means and the calmness of the murderer, and caused public outrage.

Even scholars began to study:Does the perverted murderer carry the innate crime gene?

On the basis of this case, Korean dramasMouseCome into being, toA high score of 8.7It has been on the hot list of douban for several weeks.

　

The story began in 1995, and a code-namedHeadhunting killerThe abnormal madman killed more than ten people in a row, with skillful and calm techniques and high-profile arrogance.

Every time he cuts off the victim’s head, ascollectionTake it away and leave the police with an indistinguishable headless body.

One snowy night, the headhunter came out of the mountain again and stared at a camping family of four. He did the same thing to get rid of his father and mother, and finally left two children. My brother was seriously injured, and my brother Gao Wuzhi was rescued by the police in time.

The headhunter escaped as usual, leaving no trace. But Wu Zhi recognized his photo in the hospital and identified the murderer as a nationally famous doctor.Han xujun.

In the first half of the drama, Dr. Han, who appeared as a good man, respected the old and loved the young, was gentle and considerate, and loved his wife deeply.

He not only won the trust of the public, but also received the good man card early in the audience. However, hiding the head in the snowman and his wife’s testimony made him completely exposed.

After Han Xujun’s identity was pointed out, he finally showed his ruthless true colors. He has no normal feelings, and the so-called love for his wife is only out of "wanting a second generation of Han Xujun".

With his imprisonment, this serial murder case that shocked the whole country came to an end.

The actor who plays Han Xujun is Ahn Jae Wook, the first male god of Korean Wave.

In 2020, that is, 25 years later, the son of the former victimGao Wuzhi has grown into a capable policeman..

He can’t forget the past tragedies. He often goes to prison to meet Han Xujun, who was sentenced to life imprisonment, and vent his anger and hatred in painful complaints.

Within the jurisdiction of Gao Wuzhi, incrediblyThere has been another serial murder..

The murderer despised the existence of God so much that he broke each victim’s fingers and pointed to the cross.

Its superb anti-reconnaissance ability, calm psychological quality, cruel modus operandi and ritual sense of committing crimes can’t help but remind people of Han Xujun, a perverted murderer 25 years ago.

Gao Wuzhi was aroused and determined to fight the murderer to the end. But what he didn’t expect was that his colleagueZheng policeman, friendsCui PDKnow, knowLuo prison guardandDoctor chengHave been involved in this case.

Who the hell is the murderer? Will he have anything to do with Han Xujun?

　

Start with a murder case and then continue with a murder case., is a typical move of criminal Korean dramas.

But the innovation of "spy" is that it puts forward aHigh concept setting: the killing gene will be inherited.

Twenty-five years ago, Han Xujun’s friendDanielHe’s a psychiatrist. While headhunters are rampant in committing crimes, Daniel put forward the latest research results: abnormal killers have the same genes.

And he can test whether he carries this gene in his belly, so as to judge whether he has the potential to be a future murderer.

Although people can’t change the killing gene, they can decide the survival of the fetus, thus killing the murderer in the cradle.

This proposal is not only a biological issue, but also involves the issue of human relations, so it was not passed by the government. But mothers who doubt whether their fetuses have killer genes can go to Dr. Daniel for testing.

Dr. Daniel’s institute ushered inThree anxious parentsOne is Han Xujun’s wife, who is worried that her fetus will suffer from bad inheritance;

The second is the wife of another researcher, whose fetus may have a mutated abnormal gene;

The third is a government official, who doesn’t want anyone to know about it.

Dr Daniel once explained the killing probability of abnormal gene carriers:99% will be criminals and 1% will be geniuses.

If it is determined that your fetus has abnormal genes, then do you choose to have children or have an abortion? thisDilemmaWas thrown to every unfortunate mother.

From the perspective of probability, it is much safer to choose abortion; But out of the feeling of flesh and blood, which mother is willing to give up her child?

The whole story of Spy is based on this high concept. The story 25 years ago is just a short introduction, and the story 25 years later is the focus of the whole play, because thoseChildren with abnormal genes grow up..

This play is also known as“Mouse”, which means "mouse". In the context of this play, what does "mouse" mean?

First of all, it symbolizesExperimental mice.

From Dr. Daniel’s point of view, criminal gene carriers are all mice used for experiments. Before they were born, they were judged by the test report; They grow up as if their parents were using the control variable method to influence them.

Judging from the current plot, many viewers speculated that Daniel had exchanged the test reports of three children. If he is a scientific madman, it is indeed possible.

Secondly, it symbolizesMurderer in the dark.

The first-generation killers are very similar to the second-generation killers. They are good at camouflage and wear many masks to play games. They are only interested in sadistic games. The police and the victim always stand in the light, while the murderer lurks in the dark, quietly stirring the water more turbid.

Crime and suspense are often two complementary types of drama. "Spying" is no exception. If the criminal content prohibited by 19 is challenging the audience’s functional limit every second, then the ubiquitous suspense point is the source of attracting drama.

Just as the core of Please Answer 1988 is "Guess Husband", the core of "Spy" is"Guess the son".

Twenty-five years ago, the second generation of Han Xujun, the son of a researcher and the son of a government official, died before and after.

Fifteen years ago, an unidentified boy did a lot of evil: he would feed the mice he picked up and raised to the snakes; Will threaten teachers and classmates; Can draw all kinds of scary cartoons; Poison goldfish and bury cats alive; It is also inextricably linked to the death of four other people in the family.

The boy felt that he was a monster abandoned by the gods.

Put the timeline back to the present, and the cruel serial pervert murderer has committed countless crimes. Which child was he in those days?

Up to the latest episode 6, important characters have appeared one by one, and there are not a few people suspected of committing crimes.

Zheng policemanThe enthusiastic and helpful little policeman is deeply loved by the neighborhood. One of the victims was his friend, so he actively participated in the investigation activities of the police in Gaowuzhi and often helped run errands.

Lee Seung Gi, the popular "national brother", plays Zheng Patrol.

However, the image of Zheng patrolman before and after seems a little different.

In front of the high police, he would rather be hit by a car than save the bird; But when a person is alone, because he thinks the bird is too noisy, he cleanly breaks its neck and dumps the body.

Doctor cheng, medical skill, young and promising, is very cold.

From the medical point of view, he seems to have something in common with Han Xujun. Dr. Cheng’s home is covered with photos of the victims and often appears at the crime scene.

However, with Xiaowan’s years of experience in pursuing dramas, at first, people who were like murderers were generally not murderers. Dr. Cheng is likely to have some connection with the murderer or have a strong interest in it.

balluteThe police who were transferred here to help Gao Wuzhi are always talking and not being conformal. Although he looks like a supporting role in soy sauce, he should be the son of a government official.

In the passionate discussion and infinite brain hole of netizens, in addition to the above three people, Cui PD of TV station, Dr. Cheng’s friend, Gao Interpol’s brother and Dr. Daniel are all suspected of murder.

Tuyuan Douban "Spy" TV Series Group

Under the suspense of "guessing the son", "Spying" fully mobilized the audience’s sense of participation.

Everyone has studied all kinds of details and foreshadowing in the play, guessing what it is.Who is the second-generation killer? Who is Han Xujun’s son? Are the second-generation killers and Han Xujun’s son the same person?

"Guess the son" and the subsequent trend of the plot actually lead to a more complicated proposition:If you have abnormal genes, can you "set things right" through acquired intervention?

"Spying" wants to discuss not only a biological issue, but also"beginning of life, inherent vice" and "similar in sex, far from each other"The proposition of human nature.

If sin is established, will redemption still be useful?People who are born evil, is it because genes don’t give him a chance to change? Or is the world not giving him a chance to change?

If we can persist in discussing this issue, then "Spy" will undoubtedly be a spring drama. I just hope that the next ten episodes can keep the momentum, and don’t fall into a vicious circle of high opening and low walking.
