　　On Teacher’s Day in 2019, in the smart classroom of Friendship Campus of Northwestern Polytechnical University, students were sitting around a big screen. At the other end of the screen, Fang Shuting, an interpreter of Chen Wangdao’s former residence in Yiwu, was lovingly telling the students the story of Mr. Chen Wangdao’s translation of the communist party Declaration. The students listened attentively and were deeply moved by Chen Wangdao and the older generation of proletarian revolutionaries’ persistent pursuit of truth. This was a scene in which the school launched the "5G Ideological and Political Course".

　　Northwestern Polytechnical University also initiated the "5G+ Education for Poverty Alleviation" in China. Students from the folk band, symphony orchestra and chorus of college students’ art troupe showed and explained all kinds of musical instruments and sang the song My People，My Country for the children in Wang Xiaoxue, Weinan City, Shaanxi Province, to celebrate the 70th birthday of New China.

　　This is just a microcosm of educational informatization in Shaanxi Province. Shaanxi Province is located in the northwest of China, with a large number of poverty-stricken counties and districts. The development of education in urban and rural areas is uneven, and problems such as large class size, school selection fever and shortage of teachers have been restricting the development of education. In recent years, around the three-stage development strategy of "improving environment, expanding application and deepening integration", Shaanxi Province has comprehensively deployed and promoted the construction of educational informatization and big data, explored and built a new ecology of "Internet+education", promoted the innovative development of information technology and education, and created a unique development path for promoting education equity and improving education quality.

　　"Full participation, inclusion in the assessment, one-vote veto, delayed accountability" assessment and notification evaluation mechanism

　　Elaborate the Top Project of "internet plus"

　　Shiquan County, Shaanxi Province is a poverty-stricken county in mountainous areas. At the end of 2017, it was awarded the "first batch of educational informatization pilot units" by the Ministry of Education, and it is the only regional comprehensive pilot unit among the six excellent pilot units selected by Shaanxi Province. When accepting the pilot acceptance of the Ministry of Education, Zhou Yaoyi, the county magistrate of Shiquan County, said, "Under the unified deployment of the Shaanxi Provincial Department of Education, we set up a leading group for education informatization, set up an informatization unit in the county education bureau, and clearly established three 10% funding input mechanisms. Education informatization has achieved remarkable results in promoting the balanced development of education in Shiquan County."

　　As early as 2013, Shaanxi carried out the standardization construction of educational informatization management system and mechanism, and issued evaluation standards. By the end of 2017, universities and education administrative departments of cities and counties in the province had established systematic and complete educational informatization administrative promotion institutions, forming a perfect management system and mechanism.

　　In order to improve the political position, the Shaanxi Provincial Department of Education has always been headed by the "number one" director. Especially this year, after the Education Working Committee of the Provincial Party Committee and the Provincial Department of Education were co-located, the members of the leading group were adjusted in time, with the secretary and the director as the team leaders at the same time. The Education Informatization Department was also adjusted and established, and the mechanism of "full participation, inclusion in assessment, one-vote veto and delayed accountability" was established.

　　Wang Jianli, director of the Education Department of Shaanxi Province, told reporters, "We should take informatization as the endogenous factor of educational reform, focus on solving major problems of educational reform and development, promote educational equity and improve the quality of education, and vigorously promote the development of educational informatization in the new era, providing strong support for the modernization of education in Shaanxi and the construction of a strong education province."

　　Equity of Sharing "Internet+Education" in Urban and Rural Areas

　　"The teacher on TV came to our school, so kind!" A student from a nine-year school in Yankou Town said. Not long ago, Chengbei Primary School in Xixiang County went to Yankou Town Nine-year School to carry out long-distance interactive classroom teaching activities, with Yankou Town Nine-year School as the main classroom and Chengbei Primary School and Chazhen Nine-year School as the receiving classrooms, and carried out exchange lectures and recipient classroom experience activities, with online and offline dual synchronous teaching of Chinese and fine arts, which enriched the contents and ways of long-distance interactive teaching.

　　"In the past, teachers who could read microscopes in the nine-year school in Yankou Town could not be found. Now, remote interactive teaching can solve this problem. Driving teachers to learn and teaching, our goal was achieved through experiments. " Li Qingfeng, deputy director of the Education and Sports Bureau of Xixiang County, told the reporter that at present, there are 45 long-distance interactive classrooms in Xixiang County, namely, Xixiang No.3 Middle School, Lianhua Primary School and Dahe Town Nine-year School, Xixiang No.5 Middle School, Dongguan Primary School and Gao Chuan Town Primary School, which are 75 kilometers away, and Lianghekou Town Primary and Secondary School, which are 90 kilometers away, have crossed the time and space distance and entered a brand-new learning environment together with the last class. One school has many schools and one school has many points.

　　Not only in Xixiang, in Ningqiang, but also in rural primary schools in the vast northwest, there is a micro-lesson, a test paper, a bowl of preserved eggs and lean porridge, a football, a song and a familiar face … … These stories all reflect the profound changes of educational informatization to rural schools. Since vigorously implementing the construction of "three links and two platforms", Shaanxi’s education system has made up shortcomings, promoted upgrading, and accelerated the construction of school information infrastructure. At present, it has achieved full coverage of broadband networks in all levels and types of schools in the province, and the proportion of multimedia teaching equipment in ordinary classrooms has exceeded 90%, and the gap between urban and rural environments has been narrowing.

　　How to further realize Urban-rural Education Fairness, so that every child can enjoy high-quality educational resources? By promoting the large-scale application of the platform for everyone in secondary vocational schools and primary and secondary schools, Shaanxi Province has realized the accurate push of high-quality digital education resources. The platform has been deployed in 8 cities and 75 counties (districts), achieving "one point access and sharing in the whole province", with nearly 400,000 registered teachers in primary and secondary schools and secondary vocational schools. The platform continuously integrates micro-lesson contest and other activity resources. At present, the total amount of high-quality educational resources is more than 8 million, covering all disciplines and study sections. The high-quality resources are continuously covered in rural areas, remote and poor areas, and the ability of teachers to integrate and apply has been greatly improved, realizing "sharing high-quality educational resources under the same blue sky".

　　From the past "people looking for policies" to the present "policies looking for people"

　　"Internet+Government Affairs Service" to Improve Education Governance Ability

　　The repeated attacks on campus are shocking, and the security incidents are thought-provoking. In the current digital era of open information, how can we use big data to build an "iron wall" for children, maintain campus security through information technology, and improve the ability of education governance? In the Big Data Application Service Center of Shaanxi Provincial Department of Education, you can see a series of big data construction achievements and educational governance methods. Campus security managers can access the surveillance videos of universities and primary and secondary schools in the province anytime and anywhere, even accurate to every corridor, every canteen operation room and every playground. Security incidents can be commanded in time and accurately, and emergency measures can be launched immediately in case of danger.

　　Liu Baoping, chief accountant of Shaanxi Provincial Department of Education, said, "The education system of the whole province is in accordance with the provincial party committee and the provincial government ‘ One Netcom Office ’ And ‘ Internet+government services ’ Relevant requirements, vigorously promote the construction and application of education big data, and strive to solve social hot and difficult problems such as large class size and school choice fever, which are strongly reflected by the masses. " In March 2018, Liu Baoping introduced at the press conference on student financial aid of the Ministry of Education that Shaanxi’s "precise funding" and "controlling dropping out of school" based on big data covered all students from families who set up files and set up cards, and dynamic monitoring, real-time early warning and day-to-day processing have been realized, which has improved the "accuracy" of education funding, effectively made information run more and students run less errands, and realized "changing management into service". In addition, Shaanxi Province has creatively built an "educational map big data analysis platform" to visually display the information of the province’s educational development, educational planning and the tracking of educational hot issues in the form of maps. The planning and distribution of primary and secondary schools are more closely combined with the population dynamic trend, and the layout is more reasonable.

　　The reporter also learned that Shaanxi education big data construction has gone through the stages of management information system construction, provincial data aggregation platform construction, education basic data aggregation, data governance and mining application, and realized the integration, aggregation and sharing application of core management data, and entered the era of education big data 2.0, initially forming a sharing system of education big data construction at the provincial, city/university, district/county levels, sorting out 429 business items and drawing 458 business flow charts. It has gathered more than 20,000 data of educational institutions and nearly 9 million data of teachers and students in the province, solved many hot and difficult problems through big data analysis, and formed a unique "Shaanxi model", which was affirmed by the leaders of the Ministry of Education, the provincial party committee and the provincial government, and its experience attracted colleagues from all over the country to study.

　　Build a stage for maker, innovation and creation.

　　"internet plus" gives new vitality to education in generate.

　　Shaanxi Yangling is known as the "modern agricultural city". Relying on the advantages of science and education, all primary and secondary schools in Yangling actively promote wisdom education, closely combine school education with agricultural science and technology and ecological culture, develop school-based teaching materials and digital resources of animals and plants with regional characteristics, and stimulate students’ innovative enthusiasm for exploring nature. "We actively try to enrich the educational form by using the information system composed of the core system of wisdom education, feedback device, tablet computer and physical reminder machine, organize the primary and secondary schools to carry out plant identification competitions, and solve the shortcomings of insufficient intuition in previous animal and plant teaching through novel forms, which stimulates students’ interest in learning." Zhang Shaowen, director of the Education Bureau of Yangling Demonstration Zone, said.

　　Giving birth to innovation is a natural advantage and a deep mission of educational informatization. Shaanxi Province actively promotes new modes of educational informatization, such as artificial intelligence, maker education, STEAM education and smart campus, and leads all-round innovation in education and teaching from different levels of regions, schools, teachers and students. Shaanxi has held the information-based teaching innovation competition for primary and secondary schools and secondary vocational schools in the province for four consecutive years, with 150,000 teachers and nearly 10,000 excellent micro-courses and innovative resources. Xi ‘an High-tech No.1 Primary School started writing early under the network environment, which opened a new model of primary school students’ writing. Xi ‘an Daminggong Primary School develops the characteristic school-based curriculum "Serialized Micro-class" and carries out flip classroom teaching based on micro-class. Shaanxi has also built a "Youth Maker Love Challenge Platform", held a youth "Love Challenge" carnival and a youth Maker Creative Competition, and participated in 300,000 students. A batch of school maker spaces has rapidly emerged, which has become a new growth point and breakthrough point of school informationization.

　　[Autohome Industry] Autohome E Week, learn about the major events in the field of smart electric vehicles in the week. This week, the most concerned thing in the industry is the "third chapter of the grand plan" released by Tesla. Previously, Musk himself had warmed up to related events on Twitter, which caused Tesla’s share price to soar continuously. However, after the plan was officially released, Tesla’s share price actually ushered in a low ebb; after the release of Geely Galaxy, Changan Automobile issued a lawyer’s letter accusing the former of plagiarism in design; in early March, various companies rushed to release the sales report card in February, and BYD once again led by an absolute advantage… What other major events are there this week? Let’s take a look.

■ Falling below 390,000 yuan/ton, will the price of lithium carbonate continue to fall?
Audi announces latest plan for electrification transition
The third chapter of the ambitious plan: Musk wants to use 10 trillion to transform the earth
Sales of new energy vehicle companies in February: BYD wins the championship
■ Changan accuses Geely of plagiarizing the appearance of Galaxy, Geely refutes
■ Annual revenue 45.29 billion ideal release of 2022 financial results
■ Annual revenue 49.27 billion yuan NIO released 2022 annual financial report
■BYD will launch a new brand

Falling below 390,000 yuan/ton, the price of lithium carbonate will continue to fall?

　　According to data released by Shanghai Steel Union, on March 2, the price of battery-grade lithium carbonate continued to fall by 5,000 yuan/ton, and the average price has reached 382,500 yuan/ton. Compared with the high price of 600,000 yuan/ton in November last year, the decline has exceeded 30%.

　　Li Xiang, chief executive of Li Auto, attributed the continued fall in the price of lithium carbonate to falling demand. On Weibo, he cited insurance data showing that in the first two months of 2023, passenger car insurance fell by more than 25% compared with the same period last year. "Lithium carbonate prices are going to drop significantly anyway because demand is far less than expected."

　　Some time ago, power battery giant Ningde Times launched a lithium mine rebate plan to ensure power battery market share at the expense of part of the price. From the details, the company targets several strategic customers such as Ideal, NIO, Huawei, and JK to settle part of the power battery at a price of 200,000 yuan/ton of lithium carbonate in the next three years, but the companies that signed the cooperation agreement need to entrust 80% of the battery purchase share to Ningde Times.

　　According to Reuters, CATL recently sold its 5% stake in Australian lithium producer Pilbara Mining at a price of 601 million Australian dollars. Perhaps this transaction can also objectively reflect the giant’s expectations for the price trend of lithium carbonate.

Audi Announces Latest Plan for Electrification Transformation

　　Last month, the European Union Parliament formally approved the Zero Emission Agreement for New Fuel Cars and Small Vans in Europe for 2035, agreed by the European Commission and the European Council. The goal of the agreement is to stop the sale of new fuel cars and small vans in the 27 countries of the European Union in 2035. The ban will ensure that the European Union will achieve zero greenhouse gas emissions by 2050, based on the 15-year lifespan of ordinary household light vehicles.

　　Although the German transport minister has said that he will not support the above-mentioned agreement, the German car company Audi has made more radical adjustments to its electrification transformation strategy. According to the company, starting from 2026, Audi’s new models launched for the global market will be fully switched to pure electric vehicles, and by 2033, the production of internal combustion locomotives will be gradually stopped. Under the guidance of the global strategy, Audi is steadily advancing the preparation of pure electric vehicle production at its own production base.

　　Data show that in 2022, although Audi’s sales declined by nearly 4% compared with 2021, reaching 1.61 million vehicles, it can achieve outstanding results in the field of electrification. The cumulative sales of electric vehicles reached 118,000 vehicles during the year, an increase of 44.3% year-on-year.

　　In China, Audi FAW’s new PPE plant started in June last year and is expected to start production in 2024. The first mass-produced model is the Audi A6e-tron. According to the previously announced plan, the company will provide 5 locally produced pure electric vehicles in the domestic market by 2025, and about 30 new energy vehicles globally.

The third chapter of the ambitious plan: Musk wants to use 10 trillion to transform the earth

　　On March 1, local time, Tesla held an investor conference and officially released the third chapter of the grand plan. But after the conference, the feedback from capital markets was relatively dismal. On the day after the release, the company’s stock price fell by more than 5% after hours. The next day, the company’s stock price closed down 5.85%, wiping $27.557 billion off its market value. On the third day, although the stock price rebounded, it still did not reach the level before the conference.

　　The reason for the sluggish stock price trend can be attributed to the content of the third chapter of the grand plan. Musk spent a lot of time to introduce his grand ideals, including the complete transformation of electrification, not only in the field of transportation, but also in industry, family life, shipping and shipping; to build a 240 TWh energy storage system, so that the grid can bear the pressure of full electrification; to achieve energy sustainability, to build 30 TW of renewable power generation. To achieve this goal, Musk believes that it will cost $10 trillion, equivalent to 10% of global GDP in 2022.

　　The above plan is so ambitious that some investors are worried about whether it can come true. Outside the grand framework, Tesla has not released the "details" that the outside world is concerned about, such as the legendary Model Q, 4680 battery, self-driving hardware HW4.0, etc.

　　However, in terms of manufacturing, Tesla has released a lot of strong news. The company said it will change the car production model, carry out more in-depth automated production, assemble all parts of the vehicle at the same time, and then assemble the whole vehicle according to demand, which will reduce the production cost of next-generation cars by 50%; the next-generation power platform will no longer use rare earth materials, and reduce the use of silicon carbide by 75% to save $1,000 in costs.

February new energy vehicle sales rankings: BYD wins the championship

　　According to the information released by the Federation of Passengers, the national new energy passenger vehicle market picked up smoothly in February. The market trend is expected to increase by 30% compared with January and 60% compared with February last year, basically achieving a "good start". From the perspective of sales of various new energy companies, BYD won the championship with a crushing trend.

Changan accuses Geely of plagiarizing the appearance of Galaxy, and Geely refutes

　　Some time ago, Chongqing Changan Automobile joint stock company issued a lawyer’s letter to Zhejiang Geely Automobile Co., Ltd. and Geely Automobile Group Co., Ltd., accusing the latter of "Galaxy Light" prototype car and Changan Automobile concept car, production car has a lot of similarities, suspected of infringing Changan Automobile intellectual property rights.

　　In response to the above accusations, Geely Automobile Group issued a statement saying that Geely Galaxy Light is Geely’s original design, which is completely free of plagiarism, and gave the inspiration for many details of the design. Yang Xueliang, senior vice-president of Zhejiang Geely Holding Group, retweeted the statement and said on social media: "We must have healthy competition, not internal strife; we must transform and develop, not fight in the same room; we must be united, not divided and smeared."

"Galactic Light"

　　It is reported that the Galaxy Light model came from Chen Zheng. Chen Zheng served as the global design director of Changan Automobile Group and worked under Changan for more than 20 years. Chen Zheng left at the end of 2021 and joined Geely Automobile in February 2022 as the vice president of Geely Automobile Group. His first work in the Geely era was Galaxy Light.

Annual revenue 45.29 billion ideal release of 2022 financial results

　　On Monday, Li Auto announced the fourth quarter and full year earnings of 2022. Data show that the company achieved revenue of 17.65 billion yuan in the fourth quarter, an increase of 66.2% year-on-year; gross profit margin returned to health, reaching 20.2%; quarterly operating profit was 568.70 million yuan. Annual revenue was 45.29 billion yuan, an increase of 67.7% year-on-year; annual gross profit reached 19.4%.

　　In the field of research and development, the company’s R & D investment in the fourth quarter of 2022 was 2.07 billion yuan, an increase of 68.3% year-on-year; the R & D investment in 2022 was 6.78 billion yuan, an increase of 106.3% year-on-year. In the case of increasing R & D investment, as of the end of the fourth quarter, Li Auto’s cash reserves reached 58.45 billion yuan.

　　In terms of channel construction, as of January 31, 2023, Li Auto had 296 retail centers across the country, covering 123 cities; 320 after-sales maintenance centers and authorized plate spray centers, covering 222 cities. The ideal sales expenses in 2022 are already lower than R & D expenses.

　　Facing the future, Li Auto expects to deliver 5.2-5 5,000 units in Quarter 1 in 2023, an increase of 64.0% to 73.4% year-on-year. According to Li Xiang, founder, chairperson and CEO of Li Auto, the company will challenge to win 20% market share in the entire luxury SUV market in the price range of 300,000 yuan to 500,000 yuan. It plans to build 3,000 overcharging piles by 2025, with a total cost of 10 billion

Total revenue 49.27 billion yuan NIO released 2022 financial results

　　On March 1, NIO released the fourth quarter and full year earnings of 2022. The report shows that the company achieved revenue of 16.06 billion yuan in the fourth quarter of 2022, an increase of 62.2% year-on-year, and positive growth for 11 consecutive quarters. R & D expenditure 3.98 billion yuan. The total revenue of 2022 reached 49.27 billion yuan, and the total R & D expenditure was 10.84 billion yuan; the cash reserve was 45.50 billion yuan.

　　Although revenue hit a new high, the company’s losses further expanded. Data show that in 2022, NIO’s operating loss was 15.641 billion yuan, an increase of 247.9% year-on-year; net loss was 14.437 billion yuan, an increase of 259.4% year-on-year; gross profit was 514 million yuan, a decrease of 24.6% year-on-year.

　　Facing 2023, NIO’s guidance on delivery is Quarter 1 to achieve 31,000 – 33,000 vehicles, and Quarter 1 revenue guidance is 10.62 billion yuan – 11.54 billion yuan. Since the company is currently in the transition period from NT1 to NT2 platform, there are measures such as vehicle clearance, national subsidy withdrawal, and financial interest discounts. Superimposed Q1 main delivery models are ET5, with low gross profit, resulting in greater pressure on Quarter 1’s overall financial indicators.

　　Li Bin, chairperson of NIO, said that if raw material prices reach the expected rate of decline according to the current trend, NIO will be on track to achieve the goal of break-even in the fourth quarter of 2023. In terms of sales volume, NIO’s sales target in 2023 is to double compared with 2022, about 250,000 vehicles. With the successive delivery of ET5 Touring, new ES6, new ES8 and other models, the overall product portfolio is expected to achieve the monthly sales target of 30,000 vehicles.

BYD will launch a new brand

　　BYD officially announced that it will launch a new professional personalized brand. In the future, its product matrix will include sports cars, off-road, coupe and other categories. The first mass-produced product will be a hard-core off-road product, which will be benchmarked against the Mercedes-Benz G-Class. Previously, some sources said that the overall price positioning of the brand will be comparable to that of luxury car brands such as BBA.

　　At present, BYD owns the BYD brand (Dynasty Network + Ocean Network), the Tengshi brand, and the Yangwang brand, etc., and the positioning and distinction between each brand are more obvious. The new brand to be launched this time will be internally codenamed "F Brand", which will be between Tengshi and Yangwang. And this brand is also the key layout for BYD to complete the coverage of "from home to luxury, from mass to personalization".

　　Previously, the consulting firm Reese has criticized BYD’s internal brand/category planning in the form of a report. The company believes that BYD has exploded in the layout of categories, but there is some confusion in the brand planning. The hidden danger is that BYD’s single brand covers multiple categories, which can easily lead to cognitive ambiguity; if multiple models are deployed in the same price range, the car sea strategy will lead to serious internal friction in the brand; if high-end brands lack category planning, the group will be hindered.

　　With the successive launch of new brands such as Yangwang and "F Brand", BYD’s overall development layout will undoubtedly become clearer. (Text/Autohome Chen Can)
