　　During this time, an artificial intelligence chat system called ChatGPT was like a spring thunder on the ground, suddenly exploding the network.

　　"Judging from the current general conversation experience, the biggest highlight of ChatGPT is its excellent intention recognition and language understanding ability, which makes people realize that the interaction ability of artificial intelligence has achieved leapfrog progress."Analysys wisdom institute senior analyst Chen Chen evaluation.

　　This magical human-computer interaction experience has aroused people’s enthusiasm for racking their brains to ask questions to ChatGPT, and brought it an amazing number of users: the system was launched by the American artificial intelligence research company OpenAI more than two months ago, and it has reached 100 million monthly active users in January this year. The user growth rate is unprecedented.

　　This product is very popular, and its important behind-the-scenes contributor is the technology known as the pre-trained model in the industry. In the face of the explosion of ChatGPT, domestic technology institutions and enterprises have "shined their swords".According to the latest news, the Chinese version of ChatGPT will be available to the public next month.

　　ChatGPT answers questions about itself.

　　The scale of parameters skyrockets from millions to hundreds of billions

　　"At present, pre-training technology is an important breakthrough in artificial intelligence research," explained Su Zhong, head of the Future Technology Center of Ali Research Institute.In traditional research methods, the cost of labeling has been an obstacle preventing artificial intelligence algorithms from pushing towards larger data sets, while pre-training techniques can train a large-scale deep learning model without relying on data annotations.

　　The Science and Technology Daily reporter learned that because data annotation is not required, pre-trained models can often use larger datasets, so they can choose larger model sizes – which has given rise to pre-trained large models.

　　"Compared with the previous artificial neural networks, the biggest difference of the pre-trained large model is that it is large enough, and the deep learning network has many layers, many connections, and many parameters." Zhang Jiaxing, a lecturer at the Cognitive Computing and Natural Language Research Center of IDEA Research Institute (Guangdong-Hong Kong-Macao Greater Bay Area Digital Economy Research Institute), introduced in an interview with reporters that the deep learning network around 2012 has only a few million parameters; the mainstream pre-trained model around 2018 reached 100 million parameters; the large-scale pre-trained model that has been proved to be very effective has hundreds of billions of parameters, which have been improved thousands of times in just a few years.

　　ChatGPT answers questions about itself.

　　Quantitative change leads to qualitative change. Su Zhong analyzed that in the evaluation of various techniques of the pre-trained model, the performance of the algorithm showed a rule:The larger the data size and the more parameters of the pre-trained model, the higher the output accuracy of the algorithm.

　　In addition to the large scale, Zhang Jiaxing said that the current pre-trained large model is very suitable for parallel training due to the use of new structural models. At the same time, in terms of training methods, the pre-training tasks of artificial neural networks are similar to "problem solving", such as removing a word or the first half of a sentence and letting the pre-trained model use massive big data to recover the sentence. In this way, the pre-trained model’s "problem solving" ability will get better and better. Moreover, on the basis of large language models, the introduction of instruction learning can far exceed the benefits of model fine-tuning. On this basis, human feedback can help the model better understand human intentions and receive information, and the human-machine dialogue will become more and more smooth.

　　ChatGPT answers questions about itself.

　　"ChatGPT can be said to be a landmark artificial intelligence product in terms of underlying data, core technology, user experience, etc." Zhang Xiangyu, head of basic research at Megvii Research Institute, said,The core technology of ChatGPT is the artificial intelligence language model, the key is how to make the artificial intelligence model have logical reasoning ability, and how to make artificial intelligence learn the knowledge of the whole Internet.These ChatGPTs are basically achieved, thus making great breakthroughs in decision-making and knowledge.

　　Many domestic science and technology institutions have established a presence in related fields

　　According to foreign media reports, a number of foreign tech giants are investing heavily in pre-training models and artificial intelligence generated content (AIGC) track. The reporter learned that many domestic science and technology institutions and enterprises have laid out related fields.

　　Zhang Jiaxing told reporters that the IDEA Research Institute’s Cognitive Computing and Natural Language Research Center has been in this direction for a long time, and the center has the largest open-source model system in China – the list of gods. The 98 models that have been open-sourced are fully supporting the development of China’s AIGC, exploring the development of personalized and customizable models adapted to various fields, and supporting all natural language processing (NLP) tasks.

　　"It’s great to see the emergence of AIGC and ChatGPT in the tenth year of the rapid development of deep learning. Today, all these natural language processing tasks are being unified into the ChatGPT model. We are also integrating previous models and technologies to launch our ChatGPT-like model." Zhang Jiaxing said.

　　The reporter learned from Baidu that Baidu has invested in the development of related technologies similar to ChatGPT. The name of the project is determined to be ERNIE Bot. The English name is ERNIE Bot. It will be open to the public after the closed beta is completed in March. At present, ERNIE Bot is sprinting before going online.

　　"ChatGPT mainly involves natural language processing related technologies, which is one of the applications in the field of cognitive intelligence. iFLYTEK has a long-term and profound accumulation of technologies and applications in this direction." On the evening of February 8, iFLYTEK responded on the investor interaction platform that the company has open sourced a series of Chinese pre-trained language models in 6 categories and more than 40 general fields for the field of cognitive intelligence, and launched a generative pre-trained large model task in December last year. Artificial intelligence learning machine will become the first product to land this technology, and will be released at the product level in May this year.

　　In addition, 360 said on its investor interaction platform on February 7 that the company also plans to launch a prototype version of ChatGPT-like technology as soon as possible. "AIGC technology can assist in the improvement of digital security capabilities in addition to its application in search engines," 360 said.

　　From September 22 to September 27, the 2023 Hybrid Electric Vehicle Extreme Challenge, the first domestic hybrid car exclusive event jointly launched by China Automotive Xinke and Kunming Inspection Center, was successfully concluded in Yunnan. The competition items involved a number of key indicators to measure the buying point of hybrid cars, such as pure electric cruising mileage, power loss fuel consumption, high-speed real energy consumption, and plateau mountain extreme energy consumption. During the six-day challenge, this "AI intelligent electric hybrid car" Geely Galaxy L6, which is dedicated to building a new generation of intelligent electric hybrid comfort benchmarks, played a stable role in all aspects and lived up to expectations. It won the championship of the compact plug-in hybrid car group and the single championship of plateau extreme energy consumption in one fell swoop. At the same time, in 6 of the 10 test items (idling vibration, 60km/h and 80km/h power loss constant speed driving noise, pure electric battery life, power loss energy consumption, limit energy consumption), defeated the remaining 18 participating models and won the championship.

　　"Honors" at the same level: Low key can play, truebattery lifeSuper official data

　　The Geely Galaxy L6 participating in the challenge is a 125km starship of 2023. It uses a new generation of Raytheon hybrid 8848 power system, is equipped with a 1.5T hybrid dedicated engine with a maximum power of 120kW and a peak torque of 225N · m, and is matched with a 3-speed variable frequency electric drive DHT Pro. The maximum speed can reach 247km/h. In the plateau pure electric cruising range test, Geely Galaxy L6 delivered a perfect answer. After actual testing, Geely Galaxy L6 has a true cruising range of 131km, even 6 kilometers more than the official CLTC, which is really surprising and reflects the brand’s usual low-key and pragmatic.

　　At the same time, Geely Galaxy L6’s full-speed power and stable output performance have also been verified in long-distance battery life and fuel consumption tests. The test road in the competition is connected to many mountains, the road is long and winding, and there are many curves. With the McPherson-style front suspension and the rare multi-link independent rear suspension in the same class, Geely Galaxy L6 has precise steering and stable entry into corners. After exiting the corners, it can quickly increase to the best speed, achieving a delicate balance of speed and control.

　　Single champion: extreme fuel consumption, the lowest in the audience, focusing on a cost-effective

　　In addition to pure electric cruising, another important indicator for examining hybrid models is naturally fuel consumption. The big racing car tested the fuel consumption of the participating vehicles in the standard driving mode under the same conditions as the air conditioner setting of 25 ° C and the automatic air volume. Geely Galaxy L6 led the same class with a result of 4.74L/km.

　　The competition also tested the total energy consumption of the participating vehicles under the extreme working conditions of round-trip altitude climbing, long slope and steep descent of about 359 kilometers. In this project, Geely Galaxy L6 won the individual championship with a minimum extreme energy consumption of 3.94L/km. Geely Galaxy L6 is equipped with three-speed variable frequency DHT Pro, P1/P2 motor and an engine with 20 working modes and turbocharged suction. It has a wide range of working conditions and can provide the best power solution for different car scenarios. At a time when the popularity of self-driving travel in high-altitude areas continues unabated, the economy and convenience of Geely Galaxy L6 are undoubtedly very attractive to consumers.

　　Smart Cockpit Blessings:Enjoy safety quietly, praise from drivers who travel long distances

　　It is worth mentioning that the ride of the Geely Galaxy L6 is also very comfortable. In the test of the NVH dimension of the competition, the sound pressure level of the interior noise of the Geely Galaxy L6 at 60km/h and 80km/h under power loss is only 54.23dB and 57.09dB, which is the lowest in the same group. The idle vibration is also lower than that of the same group of models, and the NVH level is leading the same class.

　　In addition, Geely Galaxy L6 leads the same level in length and width, coupled with the use of silver-plated + LOW-E technology for shading and heat insulation double-dome canopy, spacious driving space. The whole system comes standard with 10.25-inch instrument + 13.2-inch central control screen + 16.2-inch co-driver screen three large screens, full-stack self-developed Galaxy N OS vehicle intelligence system, one-touch quick interaction, zero learning seconds to get started Android system, full scene visibility can be said, which greatly meets the various needs of users in driving. During the long journey of more than 1,000 kilometers, Geely Galaxy L6 industry’s first dual-partition marshmallow memory seat has strong wrapping, sedentary and not tired, and has also been well received by drivers. In terms of safety, Geely Galaxy L6 is based on the world’s leading new e-CMA intelligent electric hybrid architecture, with extremely strict standards. The proportion of thermoformed steel in the whole vehicle far exceeds that of the same level. The Aegis battery system is equipped to achieve battery protection and ensure the safety of the whole vehicle structure.

　　Overall, Geely’s Galaxy L6 has undergone comprehensive innovation in safety, performance, comfort, and intelligence, and its overall mechanical quality has surpassed that of its peers. The various achievements of the Hybrid Electric Vehicle Extreme Challenge confirm that this industry benchmark electric hybrid sedan is indeed trustworthy. Adhering to the concept of "building an intelligent boutique car for everyone", Geely undoubtedly has high hopes for the Galaxy L6, and has indeed achieved multiple "firsts". More highlights and details about the model need to be experienced and discovered by consumers in person.

　　"Your AI data manager, help you do business together!" Recently, the Ele.me retail merchant SAAS platform "Aoxiang" officially released the "AI business assistant" function for merchants in the retail industry. Through this new business tool, merchants can intelligently generate various business key reports and key data, further enhance business capabilities and seize business opportunities.

　　This business management tool driven by artificial intelligence technology integrates advanced natural language processing, intelligent decision support and deep learning capabilities, which can provide businesses with a full range of business services including weekly report push, index change attribution, competition for business alignment, and market trend selection.

　　AI technology solves business pain points

　　"Hello, I am your AI business assistant, welcome to our platform. I will provide you with weekly report analysis, intelligent interpretation and market opportunity suggestions to make your business decisions more informed." On Monday morning, Mr. Xu, the retailer of Ele.me warehouse store, opened the new version of the Aoxiang APP and found that a new business tool was launched in the upper right corner. After clicking the "View Business Weekly Report" button, the business status of his store in the past week was clear at a glance.

　　The reporter found that the intelligent weekly report generated by the "AI business assistant" not only includes core indicators such as the valid order amount of the store, the number of valid orders, and the estimated gross profit of the store, but also includes intelligent interpretation and overall business suggestions provided by artificial intelligence based on the business operation. For example, through the operation change indicators, the "AI business assistant" will judge which indicators may be abnormal according to the historical data of the merchant. The merchant can see the data fluctuations about the net sales volume of the store, the number of goods on the shelves, the original price of the delivery fee, and the platform bears the delivery fee. Further check the reasons for the fluctuation of the data, and adjust the business strategy accordingly.

　　In addition to its own business diagnosis, the "AI business assistant" can also help merchants further analyze the surrounding business opportunities in the business district where the store is located, as well as the overall market opportunities.

　　According to the introduction, through the "AI operation assistant", merchants can query the corresponding business district according to the specific store, find the surrounding TOP stores, and compare the monthly sales of goods in the shelf rate, out-of-stock return rate, product low price rate, performance timely rate, and manual reply timely rate. These analyses can provide store managers with operational optimization suggestions and the fastest way to grow orders.

　　In addition, the "AI management assistant" can also mine the most promising products in the business circle where the store is located, and provide merchants with product opportunity analysis and product selection suggestions. At the same time, the AI will also provide operators with corresponding sales strategies based on the data.

　　The first batch of application merchants: AI is really fragrant

　　The reporter learned that, as an all-channel service SAAS platform for Ele.me retail merchants, Aoxiang has been the first in the industry to launch AI business tools after researching operators of different sizes, different industries, and different entry times. On the basis of the large model, the "AI business assistant" can disassemble the key data of store operations, and combine natural language to provide merchants with logical and clear data indicators and easy-to-understand business suggestions in a conversational mode.

　　The first batch of merchants to use "AI business assistants" also expressed "AI really fragrant" in the face of convenient new functions.

　　"The weekly report is really practical, and there is no need to summarize the data one by one for the weekly store review." Welcome Supermarket operates dozens of stores, and the person in charge of its operation said that the "AI management assistant" can quickly locate the problem through the index change, directly saving itself the time to locate the store problem. In addition, the indicators of the surrounding competition analysis are also selected accurately, which is the core focus of its daily operation.

　　Beiku Convenience said that although the number of stores it operates is not large, it feels that "weekly reports and data changes are very helpful" after using the AI business assistant, which allows merchants to quickly extract effective indicators from complex indicators and summarize them. The presentation of data and suggestions is also very intuitive.

　　"In the process of daily serving retail merchants, especially small and medium-sized merchants, we feel that merchants have obvious pain points in starting their business, obtaining industry data and analyzing business reports. Now through artificial intelligence data acquisition and analysis, merchants can effectively solve these pain points." Wang Xiaojie, head of Ele.me "AI business assistant", said that this new function is currently open to all Aoxiang merchants. Merchants can use the latest version of the Aoxiang APP. In the future, "AI business assistant" will also be gradually opened to all merchants in the retail industry in the form of tools to help merchants see their own business data.

summary

Judging from the listing situation,Belantamab mafodotin (GSK2857916) is composed of humanized targeting BCMA IgG1 and MMAF (tubulin polymerization inhibitor), which is the first targeted BCMA immunotherapy approved for marketing. At present, there are two CAR-T therapies that have been put on the market, developed by Bristol-Myers Squibb respectively.Abecma(Ide-cel), developed in cooperation with Janssen)/ Legendary Biology.Sidaki Orense injectionFrom the data point of view, the latter effect is better, the ORR is increased from 72% to 97%, and other indicators are relatively better.

Let us wait and see! From the therapeutic point of view, CAR-T therapy is at the forefront in terms of clinical data and market situation, but we can’t simply judge the advantages and disadvantages of these products. For example, better anti-BCMA CAR-T cell therapy requires more complicated preparation conditions and more expensive treatment costs, which are unbearable for ordinary families. Therefore, while continuing the existing research, it is necessary to study the potential mechanism affecting the curative effect in order to optimize BCMA targeted immunotherapy.

　　Details of participating institutions are as follows:

McDonald’s and KFC are believed to be the memories of a generation of Chinese people.

Fund Jun remembers that when he first ate it, he traveled to Shenzhen as a child. At the first meal, he clamored for McDonald’s, because he had long yearned for it in front of the overwhelming TV advertisements at that time.

There is a joke that says: the first English letter learned by kindergartens or primary school students was basically not A, but M, the M of McDonald’s.

After the reform and opening up, McDonald’s is one of the first two "foreign fast food" from the United States to enter the China market. After more than 30 years in China, I finally sold China’s business to China people.

(The first McDonald’s restaurant in mainland China at the east gate of Shenzhen)

Let’s take a look at the opening of the first McDonald’s in China.

On October 8, 1990, the first McDonald’s restaurant in mainland China &mdash; &mdash; Guanghua Restaurant was grandly opened in Dongmen Commercial Pedestrian Street, Luohu District, Shenzhen.

The queue for buying fast food went from the third floor to the first floor of the restaurant, and then turned around the whole Guanghua several times. Many people from Shenzhen went to taste McDonald’s food with their families. The customers who came to watch the grand opening of McDonald’s restaurant packed more than half of Dongmen Commercial Street.

The number of employees serving the opening of the new restaurant is nearly 1000. In addition to the first batch of more than 400 employees in China, McDonald’s temporarily transferred more than 500 employees from the Hong Kong company to help.

Guanghua restaurant at that time could be settled in Hong Kong dollars or RMB. Unexpectedly, the front of the Hong Kong dollar settlement counter was crowded with Shenzhen people who were born and raised in Shenzhen. It is said that in order to come to McDonald’s to taste the fast food chain, they all prepared a sufficient amount of Hong Kong dollars in advance.

Yes, McDonald’s in China changed its name from "foreign" to "Chinese".

On August 4th, CITIC Hong Kong Stock Exchange announced that the acquisition of the controlling interest in McDonald’s business in China Mainland and Hong Kong was completed on July 31st. This will become the largest McDonald’s franchise business outside the United States, and the partners will operate and manage about 2,700 McDonald’s restaurants in China Mainland and Hongkong market.

CITIC announced on January 9th this year that CITIC, CITIC Capital Holdings, Carlyle Investment Group and McDonald’s, a subsidiary of CITIC Group, jointly announced that they had reached a strategic cooperation and established a new company. The new company will acquire McDonald’s business in mainland China and Hong Kong for a total consideration of up to US$ 2.08 billion (about HK$ 16.14 billion).

After the transaction is completed, CITIC and CITIC Capital will hold a total of 52% of the controlling shares in the new company, while Carlyle and McDonald’s will hold 28% and 20% respectively.

CITIC Group has a total of 176 companies with total assets of 2.1 trillion yuan, and its business involves finance, resources and energy, manufacturing, engineering contracting, real estate and other fields. In recent years, CITIC Group has also begun to lay out the consumption field. Just before the acquisition of McDonald’s China, Chunxin Capital, a subsidiary of CITIC Group, acquired 100% equity of Jianlibao Trade in the hands of Uni-President Group for 950 million yuan.

Quite simply, the good times in China market are gone.

Think about it, will you go to McDonald’s and KFC every day to solve the problem of eating?

The data shows that the market share of KFC and McDonald’s in China’s fast food industry has dropped from about 57% (40% and 17% for two brands respectively) to about 37% (24% and 13% for two brands respectively).

Unable to maintain high growth, the trick McDonald’s came up with to get out of the predicament is to sell its brand management rights in the China market for the next 20 years, including the management rights of 2,200 stores that are operating.

Both companies have obtained a lot of funds for this round of transactions, which will be an important source of their next investment from me. Both companies have a large number of restaurants waiting to be renovated &mdash; &mdash; No matter what kind of restaurant, young people want a more comfortable and fashionable dining environment. In order to find consumers in the fragmented market, they have to catch up with the trend of digitalization. These all need money, a lot of money.

Fund Jun did a search in Weibo. This kind of problem actually appeared.

Many netizens are asking:

Are there any cups, toilet paper, free wifi, ketchup and straws available for free?

You can’t get ketchup after that.

I just want to ask, when boycotting American goods in the future, should McDonald’s boycott [allow sorrow]

Can I go to McDonald’s to go to the bathroom in the future?

These strange questions can only be observed later.

Today, Fund Jun continued to talk about the development of overseas brands after Chinese capital acquired them.

On May 21st, 2012, Wanda announced the acquisition of AMC, the second largest cinema in the world, for US$ 2.6 billion. This is the first international merger of China’s cultural industry and Wanda’s total transaction amount is 2.6 billion US dollars, including buying 100% equity and taking on debt. According to the M&A agreement, after the completion of the merger, Wanda Group will take over 338 cinemas under AMC and operate AMC as its wholly-owned subsidiary, and at the same time inject no more than 500 million US dollars into it every year.

A masterpiece of Wanda’s overseas mergers and acquisitions is now caught in the dilemma of loss-making and layoffs. On August 2nd, AMC Entertainment Holding Company (hereinafter referred to as "AMC"), a subsidiary of Wanda Group, released its second-quarter performance forecast, with estimated revenue ranging from $1.2 billion to $1.204 billion, net loss ranging from $174.5 million to $178.5 million, and loss per share ranging from $134 to $1.36, compared with earnings per share of 24 cents in the same period last year. In the face of performance losses, AMC also indicated that it will cut costs through measures such as layoffs. However, under the situation that the global film market is relatively depressed, AMC faces greater challenges. For Wanda Group, the frequent performance difficulties of overseas assets are not conducive to the layout of Wanda Group’s global film and television industry.

In 2004, under the auspices of Yang Yuanqing, Lenovo acquired IBM’s PC business for a total price of 1.25 billion US dollars. This acquisition, which Lenovo called "snake swallowing elephant", made Lenovo become the third largest computer manufacturer in the world.

After the acquisition, Lenovo experienced a long run-in because of cultural conflicts and changes in management. Until 2008, Lenovo lost $226 million, and Lenovo CEO was changed from Amelio, who was originally from IBM, to Yang Yuanqing.

In the 12 months to the end of March 2017, Lenovo’s total revenue was $43 billion, a year-on-year decrease of 4%. It made a net profit of $535 million, but nearly 85% of it came from the income from selling houses in the past year. Other products, including personal computers, mobile phones and servers, contributed less than $100 million in profits.

In the past fiscal year, Lenovo’s PC business was not very good, facing the global environment of the fifth consecutive year of decline in shipments. And, although Lenovo’s market share as of the end of 2016 is still the first in the world, reaching 21.7%, the second-ranked HP has narrowed the gap from 1.8% to 1.3%. An important reason for the overall market search is that people don’t change computers as frequently as before: once in the past 3-4 years, now 5-6 years.

In October 2014, Lenovo Group acquired Motorola Mobility, with a total acquisition of about 2.91 billion US dollars, and Lenovo immediately became the third largest smartphone manufacturer in the world.

After the acquisition, nearly 3,500 employees from all over the world will join Lenovo, including about 2,800 employees in the United States.

Lenovo will adopt a dual-brand strategy, that is, the parallel strategy of MOTO and Lenovo. Moto will be a supplement to Lenovo’s high-end product line in China, and its product design, R&D and operation are completely independent.

Looking back at Lenovo Mobile’s strategy, it is widely believed that Lenovo failed to grasp the transformation of Internet mobile phones or the offline channel changes initiated by OPPO and vivo.

In terms of mobile business, the revenue of Lenovo’s mobile business group since 2014 decreased by 10% year-on-year to US$ 7.707 billion. Revenue outside the China market fell by 5.4%, and profit margin before tax fell by 1.9%. At the beginning of 2014, Lenovo still had the status of the second smartphone manufacturer in China, but in the past three years, its ranking dropped to ten, and it was overtaken by Huawei, Xiaomi, OPPO, vivo and other mobile phones.

On the morning of January 12th, 2016, the signing ceremony of Wanda Culture Group’s acquisition of American Legendary Pictures Company was officially held in Beijing. Wanda Group will acquire 100% of Legendary Pictures, a well-known Hollywood film and television production company in the United States, with a cash of no more than US$ 3.5 billion (about RMB 23 billion), which is also the largest cultural acquisition of China enterprises overseas. Thomas Tull, Chairman and CEO of Legendary Pictures, will remain in office and continue to be responsible for the day-to-day operation of the company.

One year after Wanda acquired Legendary Pictures, ThomasTull, founder, chairman and CEO of Legendary Pictures, announced his resignation.

On January 17, 2017, the American media "Hollywood Reporter" reported that Thomas Tour’s resignation was not voluntary, but was under pressure from Wanda. Wanda is dissatisfied with his management level and ability to operate the Great Wall, Pacific Rim 2 and other projects.

On January 19th, Dalian Wanda Group Co., Ltd. issued a statement saying that online media reported recently that Thomas, the legendary American CEO, resigned because of the failure of Great Wall. The report is unverified and seriously inaccurate.

On August 2, 2010, Geely Holding Group officially completed the acquisition of all the shares of Volvo Car Company, a subsidiary of Ford Motor Company.

When negotiating the acquisition of Volvo, Li Shufu met with Volvo engineers. The other party made a somewhat harsh request, asking him to explain in three words why Geely’s acquisition of Volvo is the best. The scene was a little tense, and the host tried to beat the circle. Li Shufu stopped him: no problem, I can answer, three words, very good, because, "IloveYou!" "

Seven years after Geely acquired Volvo’s passenger car business, the two sides plan to jointly enter the mid-to-high-end automobile market in the form of a joint venture.

On August 4th, Link Investment Co., Ltd. was established in Ningbo, Zhejiang. This is a three-party joint venture, with Geely Automobile Holdings Limited, Zhejiang Geely Holding Group and Volvo Car Group holding 50%, 20% and 30% respectively.

Many market participants are optimistic about the cooperation between Geely Automobile and Volvo. Ni Wei, an analyst at Everbright Securities, said in the research report that they are optimistic about the long-term cooperation between Geely and Volvo based on Lectra. "The company or its own brand will switch up one of the most certain targets." The research report predicts that the sales volume of the Lectra brand will reach 15,000, 150,000 and 300,000 respectively from 2017 to 2019.

In 2016, Haier Group announced on January 15th that it would acquire the home appliance business of General Electric (GE). The acquisition amount is $5.4 billion, which will take over the personnel of GE’s home appliance department and its business base in the United States. At the same time, it will also obtain intellectual property rights and "GE" brand, which will be used as a foothold for officially opening up developed countries such as Europe and America. GE and Haier also announced that they will establish a long-term strategic partnership and explore cooperation in industrial internet, medical care and advanced manufacturing.

On the evening of March 30, 2016, Midea Group announced that Midea intends to acquire 80.1% equity of Toshiba’s white goods business with its own funds of about US$ 473 million after negotiation between the two parties. With this transaction, Midea will receive 40 years of global authorization from Toshiba brand, more than 5,000 patents related to household appliances, and the markets, channels and manufacturing bases of Toshiba household appliances in Japan, China and Southeast Asia. However, Midea’s acquisition needs to undertake about $220 million in debt from Toshiba’s home appliances.

TCL Group, one of the pioneers in the field of household appliances in China, and Thomson Company, the fourth largest consumer electronics supplier in the world, formally signed an agreement in Guangzhou to reorganize their color TV and DVD businesses and form the largest color TV supplier in the world &mdash; &mdash; &mdash; TCL&mdash; Thomson electronics company. This is also the first time that China’s home appliance enterprises have merged the mainstream business of the world’s top 500 companies.

The total assets of the merger and reorganization of the two parties will exceed 450 million euros. TCL International Holdings will become the major shareholder of the joint venture company, accounting for 67% of the shares, while Thomson will hold the remaining 33%. The newly established joint venture company has more than a dozen production bases in Europe, America and Asia, with an annual sales of 18 million color TV sets, making it the largest color TV supplier in the world.

On June 21, 2016, Tencent announced that it had acquired 84.3% equity of Supercell after consulting with Finnish mobile game developer Supercell84.3% The transaction amount is expected to be 8.6 billion US dollars (about 56.6 billion yuan). Supercell is a game giant from Finland. As of March 2016, the number of daily active users (DAU) of its games has exceeded 100 million.

According to sources, any buyer of Supercell must agree to the condition that six founders control the company. The new owner can’t force an IPO or fire the existing management team. At present, Supercell has launched games such as Clash of Tribes, Cartoon Farm and Raiders of the Island for the global market. In contrast, Zynga, which has more mobile game products, has about 21 million daily active users, while Gameloft and Glu have about 19 million and 5 million respectively. King, the developer of Candy Legend, has more than 130 million daily active users. Among them, the "local tyrant game" and "clash royale", which are well known by netizens, were also developed by them.

　　As the world’s first exclusive intelligent body control system for new energy, Yunqi has been receiving much attention since its release in April. Nowadays, the cloud system has been gradually installed on various models of BYD, allowing more users to experience the power of cloud technology. The cloud system was developed by BYD, which made BYD the first enterprise to master the 3-way 6-degree-of-freedom body control technology. BYD’s first product matrix of Yunqi, which currently includes Yunqi -C, Yunqi -A, Yunqi -P and other products, can greatly enhance our driving experience in many aspects such as comfort, handling, safety and off-road.

　　It is luxurious to carry, and Yunnian -C creates a new experience of driving and leaping forward.

　　Yunqi -C intelligent damping body control system can realize rapid and continuous variable adjustment of damping through thousands of signal inputs per second. At the same time, with the cloud algorithm, the optimal damping control scheme can be output in real time to meet the needs of users in different scenarios.

　　During the test drive of Han DM-p Ares Edition, it can be clearly felt that Yunqi -C makes the chassis "hard" by adjusting the damping, which provides greater support for the body and makes the driving and handling feeling of the whole vehicle more stable. At the same time, in the face of bumpy road conditions such as speed bumps and gravel roads, Yunxiao -C can make the chassis "soft", effectively buffering the impact of the road surface on the whole vehicle and greatly improving driving comfort. Whether it is a test of the sense of control or an experience of comfort, Yunqi -C’s performance is amazing.

　　Exercise and comfort are perfectly compatible, and Yunnian -A sets a new benchmark for luxury and comfort.

　　Yunqi -A intelligent air body control system can give consideration to both driving maneuverability and comfort, and at the same time, output precise control strategies through Yunqi Intelligent Computing Center to realize dynamic adjustment of vehicle stiffness, height and damping, and bring more detailed and diversified control to the whole vehicle.

　　In the process of experiencing Tengshi N7 equipped with the standard version of Yunqi -A, the most intuitive feeling is convenience, comfort and luxury. It can realize the functions of welcoming guests and taking things conveniently by adjusting the height, which makes it more convenient for us to get on and off the bus and move things in our daily life. In case of sudden acceleration or sudden braking during driving, the iCCT intelligent comfort control technology carried by Yunqi -A can achieve stronger anti-pitching ability, effectively restrain the vehicle from raising its head and nodding, and greatly reduce the discomfort of the passengers.

　　However, when faced with the scene of high-speed steering such as Panshan Highway, Yunqi -A can not only restrain the roll of the car body, but also integrate suspension, braking and driving through iCVC intelligent vector control technology. Even in the face of the difficult continuous mountain curve, it can easily enter and exit the curve with a very steady posture, and it is handy to control. With the help of iADC intelligent drift control system, drift is no longer the exclusive skill of "high-level players", and even ordinary people can enjoy drift with one click. Yunqi -A has achieved a perfect integration between luxury driving and interesting handling, and the overall experience is impressive.

　　Let cross-country have no threshold, and Yunqi -P brings subversive experience.

　　Yunqi -P intelligent hydraulic body control system integrates three core technologies of machinery, hydraulics and electronic control to fully meet the off-road needs of users. Yunqi -P can adjust the height, damping and stiffness. When driving U8 in mountain road, you can obviously feel that the road vibration is filtered completely, and the support is also in place in the corner. It is not like the traditional hard-core SUV, and there will be no many small vibrations. For Yunnian -P, this kind of comfort experience on unpaved pavement is unprecedented.

　　Looking up at U8 and Equation Leopard 5 under the blessing of Yunnian -P can not only realize the long suspension adjustment stroke, but also have the "hidden function" ultra-high and ultra-low mode. Therefore, even a behemoth like U8 can "hold the bottom" in extreme off-road conditions and "touch the head" in the urban restricted highland basement. At the same time, Yunqi -P with strong off-road performance has also added intelligent genes. The four-wheel linkage function can intelligently distribute the oil pressure through the central control cylinder, so that the four wheels can keep touching the ground at all times, which greatly improves the off-road passability. When parking in the wild, you can also keep the vehicle absolutely level by camping leveling function, so that the rest in the car will no longer be disturbed by terrain. It can be said that Yunqi -P greatly lowered the cross-country threshold, allowing Xiaobai to cross-country easily, bringing unprecedented experience to drivers and passengers.

　　BYD leads the industry with cloud technology.

　　Most importantly, Yunqi started from the systematic control of the vertical direction of the whole vehicle, and realized the safety of the whole vehicle. On the one hand, it can greatly reduce the risk of vehicle rollover and increase the safety of passengers by restraining the change of body posture; On the other hand, the cloud system can adjust the posture of the car body at any time through 3-to-6-degree-of-freedom fusion control under complex road conditions such as snow, mud and water. The cloud chariot system can not only effectively protect the safety of passengers, but also effectively protect the car body, and truly realize the dual protection of people and cars.

　　In the future, BYD will also launch Yunqi -X, which represents the highest level of the global body control system. At the press conference, BYD had already demonstrated the power of Yunqi -X by looking up to U9 for dancing and three-wheeled driving. Recently, Porsche Active Ride, the new hydraulic active suspension system of Porsche’s third generation Paramera, has also earned enough attention in the form of "dancing". Different from Porsche, BYD Yunqi -X is more advanced in system design ideas and realizable functions through innovative new energy architecture. This also proves that BYD has been at the forefront of the industry in the field of body control, and will continue to lead the development direction of the industry with forward-looking technical layout.

　　Through the experience of the whole family of Yunqi, we can clearly feel the overall improvement of the comfort, handling and off-road performance of Yunqi. There is no doubt that Yunqi is a super technology with the ultimate experience and safety. As BYD’s cutting-edge black technology, Yunqi’s birth not only fills the gap in the field of domestic body control technology, but also enables more domestic users to experience the high-end driving and control experience, and further realizes the technological transcendence of established western car companies and promotes the world’s automobile technology to a new height.
