The new electric MINI is finally coming! In the recent list of the Ministry of Industry and Information Technology, a brand-new pure electric MINI appeared. As the first pure electric product of the next generation MINI family, the disclosure of the new electric MINI Cooper not only reveals that the new car is about to debut in China, but also more clearly highlights the brand essence that MINI will inherit after entering the electric age-the iconic minimalist design and kart-like driving pleasure.

From the era of fuel vehicles to the era of electric vehicles, many automobile brands are actively seeking changes, and MINI’s thinking is how to continue the classics in an innovative way and carry forward its own advantages, so we see the answer given by the new electric MINI!

Inherit the essence of the brand and make the electric MINI more MINI.

In the past 65 years, MINI, as a luxury brand with great personality and design sense, has never lacked the design elements that can be recognized at a glance. The classic car body proportion, the round elements that can be seen everywhere, and the "M-shaped flag" design all bear the core essence that the MINI brand has adhered to since its birth.

From the pictures released by the Ministry of Industry and Information Technology, we can see that the new electric MINI is familiar and refreshing. This is because the new car continues a lot of classic MINI elements, and it has the same body proportion as the family. At the same time, the advantages of electric vehicle architecture make its appearance more smooth, simple and modern, which is in line with urban positioning. In addition, the wheels of the new car are also placed at the four corners of the car body to the maximum extent, presenting a classic four-wheel four-corner design, which makes efficient use of the interior space and makes the control more agile and alert.

The front of the car inherits MINI’s iconic circular headlight design, and is matched with a striking new octagonal air intake grille, which strongly outlines the dynamic momentum of the front of the car. LED daytime running lights not only have three adjustable modes, but also can interact with people, showing welcome/farewell animation when turning on/off, and the interactive experience outside the car alone is full of ceremony.

　

On the side of the car body, the black threshold enhances the dynamic boldness of vision, visually reduces the height of the car body, and shows a more dexterous posture. The door handle is semi-concealed, which brings low wind resistance, but also takes into account the face value and the convenience of opening the door in winter. As always, the roof provides a variety of choices, such as white, red, black and gradient colors, which fully meets the DIY needs of users.

The brand-new rear design is definitely a bright spot, especially the innovative taillight outline still hides the "M-flag" element, which is full of rich British style. Combined with the simple and clear tail design, it is very refreshing. In addition, the matrix LED taillights also have three adjustment modes, which will greet you with familiarity.

In the interior design, the MINI brand design philosophy of "minimalism first" has been faithfully reproduced on the new electric MINI COOPER. On the classic Mini of that year, the designer only kept three basic elements-steering wheel, circular central display and lever switch, which constituted the purest design in the car, bold and simple. Now, the front area design of the new electric MINI fully pays tribute to this pure style, and vividly interprets the MINImalist characteristics of the mini with the same three basic elements.

Interesting and fascinating.

The interior of the vehicle not only follows the classic design philosophy, but also makes the interior more simple and refreshing through exquisite interior materials and innovative digital technology, creating a warm and interesting immersive experience.

As can be seen from the disclosed information, the modern two-color fabric of the vehicle interior adopts the knitting process specially developed by MINI, all of which are made of recycled polyester fibers, with diverse structures, excellent texture and easy care. For the first time, the large curved dashboard in the front row is made of renewable fabric, with two-color design, distinct layers and excellent feel, which can be customized for decoration and color matching. The seat is made of high-quality Vescin material, and all fabrics, fabrics and yarns used in the roof and floor are made of recycled materials. The door is also covered with exquisite fabric, and the multi-function buttons are integrated under the surface of the backlight fabric, showing exquisite style in the details.

In terms of digital experience, MINI, which is good at playing, takes the "simplification" and personalized skills to the extreme, raising the traditional driving interface to a new height. MINI has built the brand’s first circular OLED central display in the car, which is not only slim in shape, but also 240mm in diameter. This high-resolution touch screen integrates rich functions. In particular, there are eight "experience modes" that people can’t put down-initial mode (Core), Go-Kart mode, energy-saving mode (Green), relaxed mode (Balance), nostalgic mode (Timeless), customized mode (Personal), party mode (Vivid) and nomadic mode (Trail). Each mode has its own specific user interface design. What is even more amazing is that the entire dashboard can present colors and patterns that match the selected experience mode through the "magic of light", which makes the interior atmosphere full.

What the mind yearns for is not only the graceful interior style and full-featured digital function, but also the MINI has this innate advantage in driving. As we all know, MINI’s outstanding kart-like sports characteristics bring a direct, powerful and dexterous driving experience, which has always made a lot of MINI powder "top". Now, based on the pure electric drive architecture, with the addition of factors such as lower center of gravity, more outward expansion of four wheels, and faster power output, the driving interest of the new electric MINI has become more prominent, and it has fully verified the sentence "You can always trust the adjustment of BMW".

The BMW Group has also provided sufficient endorsement for the outstanding quality and luxurious texture of the MINI family. Even in the era of electrification, a wide variety of R&D tests are still the only way before the mass production of new MINI models. Extreme cold test in winter, high temperature test in summer, high humidity test, high altitude test, track test, endurance test, charging test, etc., are extremely rigorous and repeated tests and verifications, only to ensure the reliable performance of pure electric drive, and more outstanding MINI classic driving interest.

Stepping into the electric age, MINI has not gone with the flow, but has been constantly exploring its own characteristics, and it has been continuously glowing with a long brand history, unique fan culture and unique product characteristics. So we have seen that MINI has brought the most unique brand-new category and brand-new vitality to the electric vehicle market, and has shown us the perfect electrification transformation of traditional car companies with practical actions.

Metal materials play an important role in the evolution of chip technology. In the process of shrinking the size of advanced processes, precious metals and their alloy materials play a key role in realizing small line width, low resistivity and high adhesion. After entering the 21st century, about 40 elements have been added to chip materials, of which about 90% are precious metals and transition metals.

Precious metal is one of the drivers of advanced chip technology. Intel has recently introduced antimony and ruthenium as metal contacts, which makes the capacitance smaller and breaks through the limitation of silicon. Previously, Intel took the lead in introducing cobalt materials into some interconnection layers of 10nm process nodes, which improved the electron mobility by 5-10 times and reduced the path resistance by 2 times.

Intel is not alone in the exploration of interconnected materials. Applied material is one of the first semiconductor technology manufacturers to use cobalt as wire material to replace traditional copper and tungsten. Grofonder also used cobalt instead of tungsten in the 7nm process. At present, Samsung and TSMC are also actively developing new interconnection materials. It is expected that in the near future, a new generation of interconnection materials, such as cobalt alloy, ruthenium and rhodium, will be on the scene, building a bridge for advanced process chips.

How to connect the roads in "Chip City"

"If a chip is compared to a city, then the transistor is its core area, which is responsible for the operation of information, and the interconnection layer is equivalent to the road of the city responsible for the traffic between information and the outside world." In an interview with the reporter of China Electronic News, Dr. Sheng Haifeng, a senior engineer of Magnesium Light, made such a vivid metaphor.

Sheng Haifeng believes that under Moore’s Law, when the transistors in the core area are getting smaller and denser, the road will become narrower and denser. When the density of the core area reaches a certain level, the transportation capacity of the road, that is, the RC delay of the interconnection layer, becomes the bottleneck of the speed improvement and power consumption reduction of the whole chip. In this case, the metal material of the interconnection layer needs to be upgraded to speed up the "road" of the transistor core area.

The continuation of Moore’s law is closely related to the evolution of interconnected materials. As the technical director, Chen Wang, a researcher from Tsinghua University, has worked for Intel and Fanlin Semiconductor, a chip equipment manufacturer, and has conducted in-depth research on high-end chip materials and advanced chip manufacturing and architecture. Chen Wang explained to the reporter of "China Electronic News" that the interconnection material is actually the wire for the interconnection and transmission of electrical signals between the front-end transistor layer and the back-end external circuit layer.

The enhancement of quantum effect is a big challenge for interconnected materials. Chen Wang told reporters that at present, the transistor has entered the sub-10nm scale in several geometric dimensions, and the quantum effect of materials has begun to be significant. If the transistor continues to be miniaturized, it will meet the challenges of materials, processes and device structures. As the core of connecting the front-end transistor layer and the outermost package ball layer, the miniaturization of interconnection materials at the middle and back ends is also facing the challenge of enhancing quantum effect.

Copper and "Damascus Process"

In the 1990s, the semiconductor manufacturing process entered the era of 0.18 micron, and the aluminum interconnection technology in the latter part met with a huge bottleneck. To this end, major semiconductor manufacturing companies in the world are looking for metals that can replace aluminum. Because copper is not expensive, has good conductivity and is easy to deposit, everyone thinks of copper in unison. However, because copper can’t be dry etched, the back-end interconnection problem can’t be solved for a long time.

In search of inspiration, an IBM engineer came to Damascus, which is known as the "garden on earth". By chance, he saw a craftsman who was engaged in metal inlaying in a remote corner.

When observing the craftsman’s mosaic technology, engineers keep seeing such scenes in their minds: carving is similar to etching, and mosaic is similar to deposition. He suddenly realized that copper can be deposited although it cannot be etched. Similar to Damascus process, engineers can etch the pattern film for metal wires on the dielectric layer first, and then fill the metal to realize multi-layer metal interconnection without etching the metal layer. In this way, the engineer successfully solved the technical problem of copper interconnection, and named this process Damascus process.

The times are progressing and the line width is shrinking. In 2018, companies such as Applied Materials used cobalt as wire material to replace traditional copper and tungsten wires in some areas.

Talking about the intergenerational changes of aluminum, copper and cobalt wires, Sheng Haifeng told reporters that copper replaces aluminum because it has better conductivity and can reduce the resistance in RC delay. In many logic chips, copper completely replaces aluminum, that is, all interconnection layers are upgraded to copper. But the substitution of cobalt for copper is different. Cobalt only has the advantage of conductivity to copper when the interconnect layer is very narrow, so cobalt only replaces copper in metal 0 layer (M0) and metal 1 layer (M1), and copper will continue to be used in other interconnect layers.

From cobalt to ruthenium and rhodium

Intel took the lead in introducing cobalt materials into some interconnection layers of 10nm process nodes, which improved the electron mobility by 5-10 times and reduced the path resistance by 2 times. The application material is one of the first semiconductor manufacturers to use cobalt as wire material to replace traditional copper and tungsten. Grofonder also used cobalt instead of tungsten in the 7nm fabrication process.

How to keep the resistivity at a low level at the scale of 20nm or even less is the core of the research and development of interconnection materials. Chen Wang said that although the introduction of cobalt has brought many problems in yield and reliability, it is a big leap in the field of interconnection materials, breaking through the existing copper material system and improving the overall performance of 10nm chips.

More importantly, the introduction of cobalt makes a good technical reserve for the later smaller node technology, and it is expected that the performance of the node will be improved more significantly after 7nm.

Interconnection materials are evolving towards ultra-thin, low resistivity, no barrier layer and low delay. At present, Samsung and TSMC are actively developing new interconnection materials. Chen Wang said that in the near future, a new generation of interconnection materials such as cobalt alloy, ruthenium and rhodium are also expected to appear.

At the same time, interconnection lines without diffusion barrier, even embedded interconnection rails under the transistor layer, are also the direction to solve the challenge of interconnection materials.

Introducing new metal materials to help advanced process

Precious metal materials play an important role in the evolution of chip technology. Chi Xiannian, an expert in semiconductor industry, told the reporter of China Electronic News that semiconductor chips are developing towards the trend of small size, high speed and low power consumption, which requires low contact resistance of contact points, good thermal stability and adhesion in a wide temperature range, and higher requirements are also put forward for lateral uniformity and thin diffusion layer.

Therefore, precious metals and their alloy materials play a key role in realizing small line width, low resistivity, high adhesion and low contact resistance in the process of shrinking the size of advanced processes.

In the process of continuous improvement of chip technology, the main challenge faced by transistors is to suppress short channel effect. Sheng Haifeng said that at this stage, the FinFET process is extended to 3nm at most. GAAFET technology is the main direction at nodes below 3nm. GAAFET mainly uses traditional materials, and the biggest challenge is process precision control.

Facing this challenge, the introduction of new metal materials is more critical. Sheng Haifeng told reporters that Samsung used lanthanum doping to improve Vt (threshold voltage). For the interconnect layer, the introduction of new materials is not only the interconnect layer metal cobalt, but also the barrier layer between the interconnect layer metal and the interconnect layer insulation layer. The function of barrier layer is to bond interconnect metal and insulating layer, and to improve the reliability of electron migration of interconnect layer. Tantalum and ruthenium are new elements that have been used and are being explored in the barrier layer.

At present, the horn of the global 2nm chip process war has sounded. In 2011, FinFET technology was introduced into 22nm node to replace planar transistor; New processes such as GAA and CFET are expected to be gradually introduced around the 3nm node.

These processes will involve a lot of material problems such as doping control and strain control. Chen Wang told reporters that at the sub-1nm node, the challenges of related materials become more and more prominent, and the quantum effect of materials will play a significant role. At that time, the quantum effect control of silicon-based materials, the atomic processing of materials and the single electron fluctuation of devices will profoundly challenge the existing material system and manufacturing technology. It is imperative to introduce new material systems, such as layered semiconductors, new principle devices and new processing technologies.

"It is reported that two-dimensional semiconductor materials are expected to help break through the advanced process of 2 nanometers due to their small size." Wan Qing, a professor at the School of Electronic Science and Engineering of Nanjing University, told the reporter of China Electronic News.

90% of the newly added chip materials are metal.

Precious metals have excellent electrical conductivity, stability and thermal conductivity, and are the key core materials in the semiconductor industry. After entering the 21st century, about 40 elements have been added to the chip materials, of which about 90% are precious metals and transition metals, which shows the importance of the application of metal materials in the chip field.

Metal materials used in the field of chip manufacturing have a higher "threshold". Chi Xiannian told reporters that the contact resistance and nano-scale adhesion should be considered in chip-level metal materials, so metals such as copper and cobalt can only be used in chip manufacturing after they are made into high-purity targets or alloy targets. At present, Hershey in Germany, Honeywell International Co., Ltd. in the United States and Tocao Co., Ltd. in Japan mainly produce chip-level copper and cobalt.

Affected by the situation in Russia and Ukraine, palladium has become one of the hottest precious metals at present. Russia’s palladium production accounts for about 40% of the global total, and palladium exports account for 35%. Palladium can be used in semiconductor components such as sensors and is also one of the important raw materials for chip packaging.

He Jinjiang, deputy general manager of Youyan Yijin New Materials Co., Ltd. told the reporter of China Electronic News that palladium and silver palladium alloy are important materials for preparing MLCC capacitors and resonators; In the packaging process of semiconductor, palladium alloy and palladium-plated wire are mainly used as wire bonding for electronic packaging instead of gold wire; In addition, palladium can be used as palladium alloy solder for precise connection of components. Based on the characteristics of palladium, new materials and applications are also being developed.

Precious metal materials have four main applications in the field of chips. Chen Wang told the reporter of China Electronic News that the first is the interconnected materials. For example, early aluminum to copper, to Al-Cu alloy and tungsten, and the latest cobalt and ruthenium under research.

The second is the metal gate material. Since Intel introduced the high dielectric-metal-gate transistor structure at the 45nm node in 2007, materials such as tantalum, tantalum nitride, titanium nitride and TiAlN have been widely used, and metal silicide contact has also undergone an evolution from titanium, cobalt and nickel to metal silicide system.

The third is metal barrier adhesion layer materials, such as titanium/titanium nitride, tantalum/tantalum nitride and other barrier adhesion layer materials commonly used in chip manufacturing and advanced packaging.

The fourth is metal materials for back-end packaging, including traditional lead-based alloys and lead-free antimony, tin, silver and indium-based alloys. In addition, the later substrate interconnection also involves a large number of precious metal materials. Among them, the nano-bottom interconnection metal, metal gate material and barrier adhesion layer material at the front end of the chip are all the frontiers of metal material research and development. Therefore, how to maintain the characteristics of high conductivity, low electromigration, uniform crystallinity, high thermal diffusivity and process integration at small scale has become the research focus of chip metal materials and the material bottleneck of the next generation of high-performance chips.

Metal price increases have little impact on chips.

Important precious metals in integrated circuits mainly include gold, silver and platinum. At present, the changes in the situation in Russia and Ukraine have had an impact on the global supply of non-ferrous metals and precious metals such as aluminum, nickel, palladium and platinum, which has led to an increase in the prices of related products and frequent fluctuations in the precious metals market. As the whole semiconductor industry chain is closed to some extent, the supply chain problem of the whole industry chain has been highlighted by the impact of COVID-19 epidemic in the early stage. Many people in the industry are worried that the fluctuation of the precious metal market is likely to further disturb the stability of the supply chain of the chip industry chain.

Precious metal is one of the important semiconductor materials, and its price fluctuation will have a certain impact on the cost of chip manufacturing. Chi Xiannian told the reporter of China Electronic News that with the fluctuation of precious metal prices, the cost of chip manufacturing will also change. For example, in the case of unstable precious metal supply chain, the purchase price of precious metals will rise accordingly, which will lead to a simultaneous increase in the price of finished chips.

However, due to the small proportion of precious metals used in chips and the small actual demand, Wan Qing believes that the fluctuation of precious metal prices has little impact on the chip industry.

Take palladium as an example. The increase in palladium price will lead to an increase in the cost of the semiconductor industry, but considering the small demand for palladium for a single semiconductor product, the increase in palladium price has little impact on enterprises with high raw material inventory water level. In addition, precious metals such as palladium can be replaced by other precious metals, so it is unlikely to face such a serious problem as supply failure.

In Chen Wang’s view, the impact of precious metal market fluctuation on the semiconductor industry chain needs to be viewed from both short-term and long-term perspectives. Chen Wang told reporters that the overall cost of the chip lies in the manufacturing cost, which mainly comes from the process cost. Precious metals are indispensable in chip manufacturing. If the international unstable factors are increasing, the shortage of a certain key metal material will continue to impact the chip price in the short term. However, due to the relatively low proportion of precious metals in the overall material consumption and cost of the chip industry, the fluctuation of precious metal prices has limited impact on the chip industry chain in the short term.

In the long run, the post-epidemic era and the continuous changes in the situation in Russia and Ukraine may bring some potential unstable factors. Chen Wang believes that the chip’s long supply chain characteristics also determine its own vulnerability. Unstable factors caused by the complex international situation may further test the chip-related industrial chain, such as affecting the layout and integration of materials, equipment and design industrial chains in the chip industry, and adversely affecting the layout and breakthrough of overall industrial optimization.

The superposition of various factors, such as the COVID-19 epidemic, makes the semiconductor supply chain in a relatively unstable state as a whole. Sheng Haifeng told the China Electronic News that the situation in Russia and Ukraine will definitely have an impact on the semiconductor supply chain, but this impact may not be limited to precious metals. For example, Ukraine is the main supplier of neon, and the complicated changes in the situation in Russia and Ukraine may affect the supply of neon. (Reporter Zhang Yiyi)

Xinhua News Agency, Beijing, August 25th Title: Nucleic acid certification, entrance and exit management, vaccination deployment … The countries that started school in autumn made these new adjustments.

Xinhua News Agency reporter Wang Linlin

Recently, many places in the country have announced the start time of autumn. Combined with the current national epidemic situation and the characteristics of prevention and control of infectious diseases in schools in autumn and winter, National Health Commission and the Ministry of Education recently issued the technical plan for prevention and control of COVID-19 epidemic in colleges and universities, primary and secondary schools and kindergartens (the fourth edition).

Compared with the technical scheme of the third edition released before, the technical scheme of the fourth edition has been adjusted and supplemented in the requirements of returning to school, the management of entering and leaving schools, the management of campus activities, and the control of key links, and put forward clear requirements.

Colleges and universities: Teachers and students should hold negative nucleic acid test certificates within 48 hours before starting school.

In terms of returning to school, the new version requires teachers and students in colleges and universities to hold negative certificates of nucleic acid testing within 48 hours before starting school, and take personal protective measures on the way. After arriving at school, nucleic acid testing can be carried out in batches according to local prevention and control requirements. Overseas teachers, students and employees will not return to school without receiving the notice from the school, and will be managed according to the relevant policies of China when returning to school.

In terms of entering and leaving the campus, the new version of the program requires that the school gate be strictly closed, that teachers and students should strictly check their identity and temperature when entering the school, and that outsiders should also check their health codes and travel cards. Reasonably set up express delivery points, strengthen the verification, registration and management of foreign sales and distribution and express delivery personnel (including names, units, visiting departments and personnel, car numbers, etc.), and strengthen the preventive disinfection of cold chain food packaging and mail express.

The reporter found out that in combination with the recent epidemic prevention and control requirements of key units and key populations, the new version of the plan has supplemented and detailed regulations on strengthening the management of public places, canteens, dormitories and activities.

These include: "major events such as the opening ceremony of colleges and universities should be held outdoors in principle", "large-scale indoor gathering activities are not organized unless necessary" and "no outsiders are allowed in the student dormitory".

In addition, in the part of implementing health education, the new version of the program has been added: actively advocate fragmented fitness activities, work and study for 1 hour, and get up for 10 minutes; Incorporate the knowledge and skills of infectious disease prevention and control into the "first lesson" …

As for the deployment of vaccination in colleges and universities after the start of school in autumn, the new version of the plan mentions that teachers and students who have no contraindications and meet the vaccination conditions should be vaccinated with Covid-19 vaccine.

"The prevention and control of epidemic situation in the education system has its particularity. The student base is large, the crowd is dense and the space is closed. Promoting vaccination should be an important measure for the prevention and control of epidemic situation on campus." Liu Peijun, deputy director of the Department of Sports Health and Art Education of the Ministry of Education, said.

Primary and secondary schools: We should do everything we can to get Covid-19 vaccination for school-age people.

It is slightly different from the requirements of returning to school in colleges and universities. For primary and secondary schools, the new version of the plan mentions that teachers and students in low-risk areas can return to school after their health status is verified by the school to meet the requirements of local epidemic prevention and control. Teachers and students who have left the country in summer, been to high-risk areas or other special circumstances must provide negative proof of nucleic acid test within 48 hours before returning to school.

In terms of entering and leaving the school gate, the new version of the plan requires that primary and secondary schools fully control all access roads to and from the campus, implement relatively closed management of the campus, and ensure that special personnel are responsible, the regional division is reasonable, and the personnel registration and investigation records are complete. No irrelevant personnel outside the school are allowed to enter the school.

Recently, according to the overall deployment of vaccination in Covid-19, all localities are promoting Covid-19 vaccination for people aged 12 to 17 in an orderly manner. In the deployment of COVID-19 vaccination in primary and secondary schools, the new version of the plan emphasizes that we should do a good job in Covid-19 vaccination for school-age people and plan the vaccination schedule reasonably.

Wang Huaqing, chief expert of immunization program of China CDC, suggested that children and adolescents are susceptible groups in COVID-19. There are four main considerations to promote vaccination for minors: First, with the continuation of the epidemic, the prevalence rate of children in some countries with serious epidemics is rising; Second, there are some severe cases among infected children, and some children die; Third, as long as Covid-19 is infected, it is a source of infection. From the perspective of controlling the source of infection, children should also strengthen management; Fourth, the global epidemic has not been controlled, and it is an indispensable part to establish a group immune barrier, and vaccination of children and adolescents.

"At present, according to the monitoring and analysis of adverse reactions, the incidence of adverse reactions of children and adolescents vaccinated with COVID-19 vaccine is not higher than that of adults over 18 years old." Wang Huaqing said.

In the part of improving the environment, compared with the third edition of the technical scheme, the reporter found that the new edition of the scheme added provisions on the safety of school food and drinking water, emphasizing that the canteen and drinking water equipment and facilities should be thoroughly inspected, cleaned and disinfected before the school starts, and the drinking water equipment and facilities should be qualified for industry testing and monitoring to ensure the safety of drinking water. Check the safety of food raw materials in school canteens. Strengthen the preventive disinfection of cold chain food packaging and mail.

As for the management of campus activities, the new version mentioned that campus gathering activities are not necessarily held, and activities that are really necessary should be reported to the local education department for approval, so as to reduce the scale, shorten the time, control the flow of people and keep the distance.

At the same time, the school should ensure students’ physical exercise time, with one hour of physical activity inside and outside the school every day; On that day, there was no physical education class, and the school should organize students to do collective physical exercise after class.

The new version of the plan suggests that there is no middle-high risk area within the county (city, district) where the school is located, and teachers and students may not wear masks in class.

Nursery institutions: teachers and nurses should be relatively fixed, and children’s gathering activities should be strictly controlled.

The requirements for kindergartens to return to the park in the new version of the scheme are roughly the same as those in primary and secondary schools: teachers and children in low-risk areas can return to school after their health conditions meet the local epidemic prevention and control requirements after being audited by the park. Before returning from overseas, high-risk areas or other special circumstances, faculty and children must provide negative proof of nucleic acid test within 48 hours.

The prevention and control of epidemic situation in kindergartens protects young children with poor resistance. According to the characteristics of children’s age, the new version of the program requires that kindergartens implement relatively closed management in the park, and irrelevant personnel are not allowed to enter the park. Parents pick up and drop off their children in strict accordance with the pick-up and drop-off time of child care institutions, so as to prevent traffic congestion around child care institutions and crowd gathering at the gate of the park. Parents don’t enter the park when they pick up their children.

In the management of activities in the park, the new version emphasizes that teachers and nurses should be relatively fixed to reduce the flow overlap between different groups. According to the epidemic situation, national and territorial epidemic prevention and control policies, children’s gathering activities should be strictly controlled and large-scale gathering activities should not be organized.

In order to ensure the nutrition and hygiene of children’s diet, the new version of the program requires strict control of purchase channels, and raw materials such as food are purchased from formal channels to ensure traceability. Strengthen the hygienic management of food and drinking water, strictly control the quality of food, and strictly implement the inspection and record system of food purchase.

Ma Jun, a professor at Peking University Children and Adolescent Health Research Institute, suggested that autumn and winter are the high incidence seasons of respiratory infectious diseases. The difficulty of epidemic prevention in nurseries is that if children have common infectious diseases such as influenza or common cold in autumn and winter, they will also have symptoms such as fever and cough. Because these symptoms are similar to those in COVID-19, the most difficult thing is to distinguish and identify them. Therefore, improving children’s physical resistance is a very effective way to prevent and control the epidemic in nurseries.

The new version of the plan mentions that kindergartens should arrange physical exercise with appropriate content and form, outdoor activities for more than 2 hours a day, and moderate and above-intensity physical activities for children over 3 years old for at least 1 hour.

Nancai Finance All-Media Reporter Feng Yuyi reports from Zhuhai.

On the evening of January 28th, Dong Mingzhu, wearing a pink embroidered silver-gray dress, appeared at the 10,000-person conference of "Gree 2024 Global Dream Festival", nearly six years after the Gree 2018 Dream Festival.

Dong Mingzhu, Chairman and President of Gree Electric, said at the meeting that night that 2023 was the best year for Gree since its establishment 33 years ago. It is estimated that the operating income will be 205 billion-210 billion yuan, the net profit will be 27 billion-29.3 billion yuan, the company’s tax contribution will be about 17.6 billion yuan, and the annual dividend in the past five years will average over 14.073 billion yuan. She mentioned that she hoped that Gree Electric’s tax revenue to the country would exceed 20 billion yuan in 2024 and strive to double its performance in the next five years. This is also the mark that Gree Electric’s revenue has returned to 200 billion yuan since 2019.

Behind the great increase in Gree’s performance

Looking back on 2023, the global air-conditioning sales market is quite positive. According to the PSI monitoring data of AVC, in 2023, the production of household air conditioners was 163.282 million units, up 12.3% year-on-year; Sales reached 156.946 million units, a year-on-year increase of 10.4%. Among them, 90.541 million units were shipped domestically, up 12.9% year-on-year; Exports reached 66.405 million units, a year-on-year increase of 7.3%.

The relevant person in charge of Gree Electric Marketing Department said in an interview with Southern Finance and Economics all-media reporter that with the recovery of the domestic consumer market in 2023, consumers’ demand for durable consumer goods such as air conditioners was released, and the air-conditioning production capacity was greatly expanded, superimposed with the ever-high temperature weather, and the global temperature rise made many European countries and regions that did not use air conditioners start to increase their demand, thus achieving the unexpected growth of the air-conditioning market.

According to industry online data, the cumulative shipments of Gree Electric in the first 11 months of 2023 increased by 1.5% year-on-year, of which domestic sales increased by 4% year-on-year, while exports decreased by 4.8% year-on-year. The growth rate was slightly weaker than that of the industry, and the market share of domestic and foreign exports declined slightly by 2.2pct and 1.8pct.

Compared with the full expansion of the domestic market, the above-mentioned person in charge said that for overseas markets, Gree has started to implement different overseas market development models, including self-owned brand model and OEM model, in addition to constantly seeking cooperation with world-renowned enterprises and establishing cooperative partnerships to realize resource sharing and complementarity, and at the same time, it has found distributors and partners in various places to form a differentiated development strategy.

According to the annual reports of Gree in 2020, 2021 and 2022, the total operating income in the three years was 170.497 billion yuan, 189.654 billion yuan and 190.151 billion yuan respectively. The outside world has been discussing that the revenue of 200 billion yuan is the "entry ticket" of the world’s top 500 companies in the past two years. It is worth looking forward to whether Gree can break through the top 500 companies with its performance in 2023.

Dong Mingzhu had previously responded by saying that she didn’t care about falling out of the world’s top 500. She said at the party on the 28th, "I still reiterate that Gree Electric doesn’t care about the stock price because we don’t live on it."

Industry insiders predict that in 2023, with the blessing of many favorable factors such as the right time, the right place and the right people, the domestic and foreign markets of China air conditioners will perform remarkably. However, in the current situation that the domestic air-conditioning demand is narrowing, and the overseas export market is always faced with uncertainties such as geopolitics and exchange rate fluctuations, it will be difficult to replicate the higher shipment scale in 2024.

The road to transformation is full of thorns

With air conditioning as the core category, air conditioning business in Gree Electric accounts for about 70% of the total revenue in the first three quarters of 2023. In order to reverse the single development model that relies heavily on air-conditioning business, Gree has been emphasizing diversified development in recent years, trying to show the world a multi-faceted and three-dimensional enterprise structure and competitive strength.

All-media reporters of Southern Finance and Economics combed Gree Electric’s financial reports in recent years and found that the diversified layout of Gree is not comprehensive. The logic is basically to extend the industrial chain through the upstream and downstream layout of household appliances, from smart equipment and precision molds in the vertical direction of the industrial chain to refrigerators, washing machines, water heaters and drinking fountains in the horizontal direction of products, and then to new energy vehicles, mobile phones and prefabricated vegetables, and so on, stepping on the tuyere of almost every industry.

Taking intelligent equipment as an example, intelligent equipment has always been a main line of Gree’s diversified business development. Tracing back to this main line so far, Gree has made great strides.

In 2013, Dong Mingzhu personally established the Automation Office, Automation Equipment Manufacturing Department, Automation Technology Research Institute and Intelligent Equipment Technology Research Institute, which defined the development direction of "independent innovation and independent creation" and opened Gree’s entry into the field of intelligent equipment.

In 2015, Gree Intelligent Equipment Manufacturing Division independently established Gree Intelligent Equipment Co., Ltd., and proposed industrial robots and high-end CNC machine tools as the company’s two major research fields in the future. The industrial robots independently developed by Gree also made their debut. At the same time, Midea and Yaskawa Electric set up a joint venture robot company, took a stake in KUKA for the first time, and officially announced their entry into the robot industry.

At the end of 2022, Gree established Zhuhai Gree Prefabricated Vegetable Equipment Technology Development Co., Ltd., and the Guangdong Prefabricated Vegetable Equipment Industry Development Federation, which was led by Gree in the following year, was officially unveiled, and a prefabricated vegetable smart factory was built to March into prefabricated vegetable equipment in an all-round way.

Yang Ce of china galaxy Securities Co., Ltd. believes that Gree Electric is better than sales in revenue growth, which is expected to benefit from the improvement of income diversification level after the company’s product structure optimization and business transformation.

However, judging from the revenue structure in the first half of 2023, Gree’s industrial products, smart equipment and green energy projects accounted for 5.53%, 0.25% and 2.94% of the revenue respectively. The "second growth curve" created by Gree still has a long way to go and faces many challenges.

Now, it has been four years since Gree put forward the reform of "new retail" mode, and Gree has continuously laid out new retail channels to reduce operating costs. According to the latest public information, starting this year, Gree will fully implement a new retail model in Shandong, Guangdong and other provinces, in which dealers directly sign contracts with the company’s Zhuhai headquarters and place orders from the cloud platform, so as to shorten the sales chain.

Regarding the marketing reform, Dong Mingzhu had previously responded to the media, saying, "The first thing to reform is to change your own life. Gree’s past marketing model was created by me, and it hasn’t changed much for more than 20 years. But the background of today’s era is completely different from that of that year. The arrival of the Internet era is indeed a huge challenge for Gree. "

Special feature of 1905 film network On the 11th day of Cannes Film Festival, all 21 films of the main competition were finally shown. The three films that appeared on the last day were LGBTQ movies from France, Russian director Sergey Dvortsevoy’s and Ceylon’s last-minute shortlist.

　

The day before the Palme d ‘Or was officially announced, the "One Concern" unit took the lead in winning the prize. Bi Gan’s works, which had caused extensive discussion before, were not harvested, and the grand prize was won by Swedish fantasy movies.

Retro interpretation of love in "Stab in the Heart" & Color "Little Guy" is exhausting.

　

Among the films in this main competition, "Stab in the Heart" is a relatively large category. The main characters of the film are a lesbian couple making same-sex movies and their LGBTQ friends. They exaggerated the abnormal killings they encountered in the form of images, and under the picture full of retro flavor and extreme eroticism, "Stab in the Heart" actually tells the story of two extremely pure love relationships, one is a lesbian couple who fell in love but failed to stay together in the film, and the other is two little boys in where will you go who were brutally separated by their father in the movie. Compared with the simple plot, The Stab in the Heart is more like an experimental tribute to the shadows.

　

There are "rumors" that Ayka, the heroine of "Little Guy", is likely to launch an impact on the best actress award, and the film continues the consistent style of Russian films at international film festivals — — Focus on social problems and endless suffering of the bottom people. Ayka, who just gave birth, not only has no job, but also has debts to repay. Throughout the film, the director led the audience to "bear" Ayka’s predicament with a strong sense of documentary camera language, and experienced her double physical and psychological pain. Tragedy is real, but as a film work, endless repetition makes people feel distressed about the role and endless fatigue and aesthetic fatigue. In short, it is another work with more practical significance than artistic expression.

Swedish film won the "One Concern" unit award. Bi Gan’s "The Earth" is unfortunately zero.

　

On the day before the official closing of the film festival, the "One Concern" unit announced the results of various awards. As the chairman of the jury of this unit, actor Benicio Del Toro spoke first at the award ceremony. He evaluated the 18 finalists as winners in a sense, and the excellent quality of each work shocked several judges. However, they still need to select five works to share five awards.

　

Previously, Bi Gan’s "The Last Night of the Earth" was widely discussed after the screening, and it was also highly anticipated by domestic media and fans. Unfortunately, however, the film did not win any awards that day. A focus unit award was won by the Swedish fantasy film Border. In addition, The Girl, which was highly praised during the Cannes Film Festival, won the best performance award. Victor, the leading actor, plays a deformed ballet dancer in the film. Only 16-year-old, he is still in school today. The director received the award for him and expressed the hope that this role would express his understanding and support for this kind of group.

Ceylon’s Wild Pear Tree focuses on father and son and the script of the times is solid and informative. 　

　

Ceylon’s new work Wild Pear Tree, which was added to the main competition unit at the last minute, was scheduled for the last screening on the last day. The film is more than 3 hours long, which is the most shortlisted film in this year’s Palme d ‘Or. Fortunately, compared with the last one that won the Palme d ‘Or, the appreciation of Wild Pear Tree has improved a lot, and the script is absolutely solid, but the intensive lines bring so much information that the three editors all sigh: these three hours seem to have finished reading a book (with English subtitles) in the cinema.

　

"Wild Pear Tree" has designed several important scenes with the hero as the dot, and each scene contains a lot of dialogues. Through these life-oriented lines, Ceylon shows the personality of the younger generation in Turkey and the confusion they face, as well as the huge "generation gap" between the young and middle-aged generations: the boy in Grade Two shows "blind self-confidence" when facing famous writers, which makes people feel angry and can’t help but smile for his childish courage; The scene of middle-aged people who have successfully dropped out of high school and "taught" young people who have received higher education but are still confused in society with their own social experience also makes the audience’s empathy particularly real.

　

There is no doubt, however, that the overall plot line running through Wild Pear Tree is still the relationship between father and son. Two men with different personalities and egoism maintain an uneasy relationship in most parts of the film. My father, who has been working hard, always has a restless heart, while my son, who thinks he has grown up, has been silently remembering his childhood teachings in his heart while looking down on his father. Both of them are persistent enough about what they like.

　

My son’s first novel "Wild Pear Tree" became an opportunity for the relationship between father and son to break the ice. When everyone, including his closest mother, didn’t finish reading this book, his father had already learned the contents of "Wild Pear Tree" by heart. The film also completes the topic in this part: in fact, fathers and sons are like the fruits of wild pear trees. They look unpleasant on the outside, but they taste delicious.

　　At the press conference on the prevention and control of novel coronavirus epidemic in Beijing on December 19th, Tu Zhitao, member of the Party Committee of Beijing Municipal Health and Health Commission and director of Beijing Administration of Traditional Chinese Medicine, said that recently, a large number of positive infected people in Beijing have been rehabilitated in isolation at home. According to the requirements of epidemic prevention and control and the actual situation in Beijing, in order to do a good job of releasing isolation and returning to work after home rehabilitation of infected people, and further optimize the prevention and control policies, after organizing disease control and clinical experts to study and demonstrate, the suggestions for releasing home isolation of positive infected people are as follows:

　　First, for home isolation rehabilitation infected people, from the date of symptoms, home isolation must be over 7 days.

　　Two, such as home isolation for 7 days, without the use of antipyretics, fever symptoms subsided for more than 24 hours, and other symptoms improved, can lift the isolation; If there are still fever symptoms, release the isolation after the fever symptoms subside for more than 24 hours and other symptoms improve. After the isolation is lifted, you can return to work without nucleic acid and antigen testing.

　　Three, special industries and jobs isolation rehabilitation and return to work requirements, in accordance with the provisions of the competent department of industry. (Reporter Wu Wenzhao)

　　

Dominic Frisby, a gold analyst and founder of Flying Frisby, said that the officially disclosed gold holdings in China are far from the reality. He said that China is secretly buying a large amount of gold, which is twice as much as that of the United States. He thought that the country could consider supporting the RMB with gold. He predicted that the price of gold will reach $3,000 next year, and bitcoin will exceed $100,000.

　　

According to the latest data from China, the Bank of China bought gold for the 12th consecutive month in October. The World Gold Council (WGC) reported that the latest purchase was about 23 tons, increasing the total holdings to 2,215 tons. Generally speaking, the China government has recently become one of the largest gold reserves, and the central bank’s gold purchases seem to have reached a record high this year.

　　

Frisbie told Kitco News that although China has become the leader in gold accumulation, the actual figures are much more important.

　　

"They are gently announcing the news, and China is ambitious," Frisbie said. "I may study this problem more deeply than anyone else, and I will tell you why China’s gold holdings may be 10 times what they say. The mathematical calculation in this regard is very simple."

　　

China is the world’s largest producer and importer of gold, but Frisbie said that its motto is "We can’t be too dazzling".
