I. Overview of Industry Development

(A) the industry environment

5. Honors won

L Won the TOP100； of Shanghai Hard Core Technology Enterprise in 2022; L obtain AAA credit enterprise certificate; L was rated as an outstanding contributor to talent training by Southeast University;

1, the United States to engage in monopoly frequently suppressed high-tech enterprises in China.

Since the beginning of Sino-US trade friction, since 2018, the US government has repeatedly imposed unilateral sanctions and so-called "long-arm jurisdiction" on other countries on the grounds of national security and diplomatic interests. During this period, in many key technical fields, such as transportation, communication technology, wireless communication testing, artificial intelligence, etc., more than 300 enterprises in China were technically blocked, and the acquisition of American-made goods (including goods and technologies), the supply technology and parts purchase, and the signing of contracts were suppressed. The essence behind it is nothing more than monopoly, which restricts the technological development of related enterprises in China and foreign trade.

In addition, with the gradual entry into force of epidemic prevention and control and unconventional stimulus policies, the economic recovery of all countries in the world is unbalanced and inadequate, and the world economy still faces great uncertainty, which has caused new impacts on the cooperation among countries in the Belt and Road Initiative, prompting China to pay attention to independent industrial innovation internally and actively explore new paths for the development of the Belt and Road Initiative.

2. The world will share the market opportunity of China wireless communication test equipment.

In recent years, China’s attention and support for the wireless communication and RF microwave test instrument industry has been increasing, the technical level of domestic enterprises has been continuously improved, and the advantages of domestic equipment in product cost performance and after-sales service have gradually emerged. With the rapid development of 2G blank, 3G follow-up, 4G synchronization and 5G leading, China has become one of the countries with stable global economic development and good business environment, which further promotes the localization of domestic wireless communication test equipment, especially in the field of wireless communication testing, and gradually presents the characteristics that the domestic market realizes import substitution and exports to overseas markets such as Europe and America.

3. The national revitalization policy continues to bring great opportunities to the development of the industry.

The subdivision industry of wireless communication and RF microwave test instruments is the basic and strategic industry of the national economy, which has a strong pulling effect on the national economy and has been supported by national policies. In recent years, with the formulation and implementation of a number of policies, such as Made in China 2025, Special Plan for Scientific and Technological Innovation in the Field of Advanced Manufacturing Technology in the Thirteenth Five-Year Plan, the Tenth Five-Year Plan and the Outline of Vision in 2035 (draft), China’s attention and support for this industry has gradually increased. The policy provides financial, tax, technical and human resources support for the wireless communication and RF microwave test instrument industry, and creates a good domestic business environment.

(2) Industry characteristics

1. Financial strength and technological innovation have pushed up the industry gap barrier.

Wireless communication test equipment industry is a typical knowledge and technology-intensive industry, and the factors such as technology, capital, talents and industry standard formulation lead to high barriers to entry. Due to the periodic technological changes in downstream industries, enterprises in the industry continue to invest in research and development to ensure that they remain ahead in the new generation of technology. At present, the ratio of R&D expenses/operating income of well-known manufacturers in the industry has remained above 10% all the year round.

2. The import of high-end test equipment is highly dependent.

At present, due to the fact that China’s wireless communication test equipment is still in its infancy, the market scale is relatively small in the communication and electronic manufacturing industry, and the technical difficulty and high precision are required, as well as the industry is restricted by foreign invisible technical barriers, China’s high-end test equipment relies on imports, such as German technology, Germany’s Rhodes and Schwartz, American national instruments and other foreign large enterprises, and domestic equipment is in an embarrassing situation. According to statistics, in 2020, domestic test equipment will contribute less than 30% of the income to the market of electronic measurement and test instruments, and the remaining 70% will come from imported instruments. China electronic test equipment market has a large import substitution space.

3. The iterative R&D and construction stage of communication technology has become the critical point of periodic demand.

The application scenario of wireless communication test equipment is closely related to the communication industry, mainly used in communication, electronics and other industrial manufacturing industries, which have obvious cyclical characteristics due to the influence of technical standards and changes in supply and demand. Usually, the demand for test equipment is relatively high in the development period and construction period of the new generation of communication network standards, while the procurement between the two standard periods is mainly to maintain engineering test instruments, which belong to durable goods, and the demand is relatively stable. Take the three major domestic operators as an example, the capital expenditure of each generation of mobile communication technology will maintain a rapid growth during the research and development stage and construction period, during which a large number of equipment and corresponding test equipment need to be purchased, while upstream communication equipment manufacturers, antenna manufacturers and module manufacturers also need to increase the purchase of test equipment to ensure that their products meet the requirements of the new generation of technology.

Second, the industry competition pattern analysis

(1) Development of global wireless communication and RF microwave test instrument industry

(1) Market size

1. Wireless communication test instrument market

With the continuous improvement of global industrial level and the arrival of digital era, as well as the rapid development of information technology, electronic manufacturing, national defense and aerospace and other related industries, wireless communication test instruments have formed a huge market scale. It is predicted that the global wireless communication and RF test instrument market will continue to grow steadily in the future. By 2024, the market scale will reach 88.464 billion yuan, with a compound growth rate of 5.79% from 2020 to 2024.

China’s wireless communication test and measurement instrument industry started relatively late, and there is still a certain gap with foreign leading enterprises in key technologies. In the fields of national defense science and technology such as military industry and aerospace, some national research institutes have strong technical strength, but their marketization degree is low.

In recent years, with China gradually becoming the manufacturing center of the global electronics industry, the development potential of the domestic wireless communication test instrument industry has been stimulated in combination with the domestic industry and policy trend of replacing imports. In the future, with the vigorous development of domestic wireless communication, the market scale growth rate of China wireless communication and RF microwave test instrument industry will be significantly higher than the global average. It is estimated that by 2024, the market scale will reach 25.065 billion yuan, with a compound growth rate of 13.13% from 2020 to 2024.

(B) Industry demand analysis

1. The process of 5G construction accelerates the growth of wireless communication test demand.

The R&D and large-scale commercialization of 5G are inseparable from the participation of wireless communication test equipment manufacturers. China officially issued the commercial license of 5G in 2019. At present, 5G technology is gradually turning to large-scale application. In this process, communication equipment manufacturers, terminal manufacturers and application module manufacturers need to increase the procurement of test equipment to ensure that their products meet the requirements and specifications of the new generation of mobile communication technology. Different from the traditional mobile communication technology, 5G has three characteristics: high speed, low delay and wide connection. The integration of both base stations and terminals is getting higher and higher, and the performance test difficulty and test time of 5G communication equipment are doubled. With the help of advanced test and measurement instruments, designers of downstream manufacturers can explore new signals, channels, scenarios and topological structures, and further verify the commercial capabilities of equipment and solutions, so wireless communication testing becomes more important.

The increasing demand for antenna testing in 5G base stations drives the development of test equipment industry. At this stage, the scale of China’s 5G base station construction is still showing explosive growth. According to the data of the Ministry of Industry and Information Technology, in 2021, the total number of mobile communication base stations in China reached 9.96 million, with a net increase of 650,000. Among them, there are 5.9 million 4G base stations and 1.425 million 5G base stations. Over 650,000 new 5G base stations were built throughout the year, and the number of 5G base stations in China accounts for nearly 70% of the global total. According to the data of iResearch, it is estimated that by 2024, the number of 5G base stations in China will reach 6.21 million. Because the antenna test of 5G base station needs to be completed in the shielding box, with the increase of antenna test demand, the market demand for shielding box continues to expand, and the wireless communication test equipment industry will develop steadily.

The application of 5G technology will greatly increase the demand for test equipment and solutions. According to the data released by the Global System for Mobile Communications, the number of China’s 5G network users will increase from 5 million in 2019 to 807 million in 2025, and the proportion of 5G network users will increase from 0.3% in 2019 to 47%. By then, the enhanced mobile broadband, massive Internet of Things and high reliability and low latency connection supported by 5G will drive the demand of terminal equipment for different test functions, and the demand for test solutions that can verify the performance of high-density data will also increase.

Frost&Sullivan predicts that by 2024, the global market of 5G test equipment and solutions is expected to reach US$ 2 billion, with a compound annual growth rate of 11.5%.

2. The increase in the number of Internet of Things connections enhances the market space for communication testing.

With the commercialization of 5G on a global scale, the era of the Internet of Everything has begun, and the number of terminals that need signal transmission will increase greatly in the future. It is necessary to test the equipment performance, network performance, terminal security and other aspects to realize large-scale commercial use of Internet of Things technology.

Intelligent IOT products need all kinds of communication test instruments to test and verify the products in the aspects of identification, information reading, information transmission and sharing, and the market scale of communication test has expanded rapidly. According to data released by the Global System for Mobile Communications, the total number of Internet of Things connections worldwide reached 12 billion in 2019, and it is estimated that by 2025, the total number of Internet of Things connections worldwide will reach 24.6 billion. With the increase of the number of connections and the improvement of network complexity, the difficulty of testing requirements is also increasing. At present, the main application scenarios of Internet of Things include smart city, smart transportation, smart home, industrial Internet of Things, car networking, wearable devices, etc. After the large-scale application scenarios of Internet of Things, the scale of wireless communication testing market will be greatly improved.

3. The ubiquity of Beidou satellite application enhances the urgency of product testing market demand.

At present, Beidou satellite navigation system has formed a complete industrial chain consisting of Beidou basic products, application terminals, application systems and operation services, and has been widely used in transportation, public safety, agriculture, forestry and fisheries, hydrological monitoring, weather forecasting, communication time system, power dispatching, disaster relief and disaster reduction, and other fields, resulting in remarkable economic and social benefits. According to the data released by Navigation and Positioning Association, the total output value of China’s satellite navigation and location service industry reached 403.3 billion yuan in 2020, an increase of about 16.9% compared with 2019. Among them, the core output value of the industry, including chips, devices, algorithms, software, navigation data, terminal equipment and infrastructure, which are directly related to the development and application of satellite navigation technology, increased by about 11% year-on-year, reaching 129.5 billion yuan, accounting for 32.11% of the total output value, with a slightly higher growth rate than last year. The associated output value derived from satellite navigation applications and services increased by about 19.9% year-on-year, reaching 273.8 billion yuan, accounting for 67.89% of the total output value.

With the advent of the 5G era, it will promote the ubiquity of Beidou satellite navigation user terminals in various fields of the national economy, and the quality of its products will also become one of the important factors affecting the healthy development of China’s satellite navigation industry and the formation of the application market. At present, there are many kinds of Beidou user terminals, but there are still a series of problems such as incomplete testing and errors in function, performance and reliability.

Therefore, it has become a widespread consensus and urgent demand to conduct accurate, comprehensive and standardized performance tests on Beidou satellite navigation products to ensure that their performance meets the corresponding technical specifications and the system can operate normally, reliably and stably. This will put forward higher requirements for the technical end and service end of wireless communication test equipment, and will also bring broader market demand for the wireless communication test equipment industry.

(III) Information on key enterprises in the industry

Iv. risks faced by the company and countermeasures

(A) the risk of intensified market competition

The wireless communication test instrument industry has long been monopolized by foreign giants, especially the high-tech products are mainly controlled by internationally renowned enterprises in Europe, America, Japan and other countries and regions. In recent years, with China’s increasing attention and support to the wireless communication test instrument industry, the technical level of the industry has been continuously improved, and the advantages of domestic equipment in product cost performance, after-sales service and geography have gradually emerged. The gradual rise of domestic industries may attract the attention of foreign competitors and intensify market competition. At the same time, with the rapid growth of the market demand for wireless communication test instruments in China, more domestic companies will be attracted to join the competition in this industry. If the company can’t carefully grasp the market trends and development trends of the industry, and can’t carry out technological innovation and business model innovation in time according to the technological development and customer demand, there is a risk that the business will be adversely affected by the weakening of competitive advantage.

Countermeasures: Wireless communication test equipment industry is a typical knowledge and technology-intensive industry, and the factors such as technology, capital, talents and industry standard formulation lead to high barriers to entry. Chuangyuanxinke has been deeply involved in this field for many years, and has a good accumulation of technology, capital and market. With the help of China’s leading position in the fifth generation mobile communication technology, it has actively deployed 5G/6G and millimeter wave, semiconductor testing, satellite communication, car networking and other fields; While doing a good job in expanding the domestic market, we will continue to expand overseas markets and strive to build a market-oriented marketing team; Continue to increase R&D investment in core technologies such as RF microwave, signal processing, basic algorithms and customized RF chips, make full use of the accumulation of cutting-edge technologies of major national projects, closely strengthen the integration with Industry-University-Research of research institutes such as Southeast University, establish joint research platforms with more universities, focus on customer pain points, and rely on innovation centers to jointly develop better application solutions with customers. In the field of wireless mobile communication test technology, with the development of 5G/6G and the Internet of Things, the company can overtake in corners and gain a place for the country in the global communication test instrument market competition.

(B) the risk of brain drain

As a high-tech enterprise in the field of wireless communication and RF microwave testing, the management and other core personnel of the company are mostly senior experts with complex knowledge. They not only have rich industry knowledge, master relevant professional technology, and are proficient in the performance of various instruments and meters, but also have good management experience and business risk management experience, which can ensure the smooth progress and sustained and steady development of various businesses of the company. With the intensification of industry competition and talent competition, it will bring some pressure on the company to retain the above-mentioned core personnel. If the company cannot maintain a good incentive system and team work environment, the loss of the above-mentioned core personnel will adversely affect the company’s business development.

Countermeasures: implement the company’s achievement sharing mechanism, and ensure that employees can share the achievements of the company’s rapid development through a series of incentive measures such as option schemes. The Company has implemented equity incentive twice, with a total of 113 incentive targets, accounting for 43.96% of the total employees at the end of the reporting period, and 6,307,300 shares were encouraged, accounting for 4.42% of the total share capital at the end of the reporting period. The company will use various incentive mechanisms to fully mobilize the enthusiasm and creativity of talents, especially core technical talents, create a good corporate culture, enhance the cohesion of the company and increase the sense of belonging of employees; Establish and improve the talent reserve mechanism, provide employees with more learning and training opportunities, establish a set of future-oriented training plans, provide employees with growth opportunities and development space, and fund employees to study for doctoral degrees in Southeast University; Stimulate the maximum "potential" of employees, while avoiding the phenomenon of "ceiling" of talents and increasing the overall development space of employees; Establish a good and perfect employment mechanism, and use legal means such as Labor Law and Anti-Unfair Competition Law to protect the legitimate rights and interests of the company.

(C) Technology R&D and product development risks

The wireless communication and RF microwave test industries are technology-intensive industries. With the rapid iteration of communication technology, increasing application scenarios and highly complicated communication equipment, the requirements for the test capability of communication test instruments and meters have been further improved. The company’s R&D mode is a combination of independent R&D and undertaking external scientific research projects. If the company’s R&D is not forward-looking, it fails to make a correct judgment on the market development trend and the experience and technology accumulated by external scientific research projects cannot be applied to the company’s products, it may lead to the technology R&D achievements not being recognized by the market and have a certain impact on the company’s operating performance.

Countermeasures: While insisting on independent research and development, the company will jointly track cutting-edge technologies with universities and leading enterprises with strong scientific research and technology accumulation in the fields of wireless communication and satellite navigation; By undertaking major national science and technology projects, we will continue to strengthen technology accumulation. At present, the Dongda-Chuangyuan Electronic Measurement Technology Research Center jointly established by the company and Southeast University has entered the third phase (microwave, millimeter wave, terahertz and communication test and measurement technology and instrument research and development); Establish an advanced satellite navigation technology collaborative innovation technology center with a famous university in China to track and study Beidou navigation related testing technology; In conjunction with Shanghai Institute of Advanced Studies, Chinese Academy of Sciences, the project "Prototype Testing and Verification of 6G Basic Chip for New Network" was undertaken, and 6G network testing technology was laid out.

(D) The risk that key core devices depend on imports.

The key core devices of wireless communication and RF microwave test instruments, such as high-end chips, rely heavily on imports. Some key core devices of the company’s equipment are dependent on foreign brands. If the above-mentioned key core devices are affected by factors such as trade prohibition and control in exporting countries, the company can’t purchase them in time as needed, which will adversely affect the company’s production and operation.

Countermeasures: At present, the key core devices mainly purchased by the company are general commercial products, and the management of supply chain will be strengthened. By selecting multiple suppliers, the risk of relying on centralized procurement will be dispersed, and at the same time, the production demand of the company will be guaranteed by establishing safety inventory; On the other hand, the company is also actively improving product technical solutions, increasing investment in millimeter-wave chip customization, and reducing the risk of relying on imports for key core devices; At present, we have established cooperative relations with many domestic core device suppliers to realize localization of some core chips, which not only solves the problem of neck sticking, but also reduces the product cost. In the future, the company will actively explore more cooperation with domestic enterprises.

(E) Risk of government subsidies

Most of the government subsidies of the company come from the funds for scientific research projects. If the company uses the funds for scientific research projects irregularly, there may be the risk of returning the special funds for scientific research and being punished, which will adversely affect the company’s production and operation.

Countermeasures: In view of the rational use of scientific research funds, the company has formulated a series of management measures and rules and regulations, such as "Measures for the Administration of Major Special Funds and Budget Implementation", and the capital expenditure is approved and used in strict accordance with the requirements, thus ensuring the smooth implementation of the project budget and ensuring the standardized and orderly use of scientific research funds.

(six) the risk of failing to obtain the qualification of qualified suppliers in time

The company has not yet obtained the qualification of qualified suppliers of Huawei and TSMC, and mainly sells test instruments and related equipment to Huawei and TSMC through its controlling shareholder Chuangyuan Electronics. The controlling shareholder and actual controller of the company have issued the Letter of Commitment on Avoiding Horizontal Competition and the Letter of Commitment on Regulating and Reducing Related Party Transactions. Chuangyuan Electronics is engaged in the business of selling test instruments and related equipment to Huawei and TSMC, all of which are purchased from the company at the same purchase price as the sales price. If the company obtains the certification of qualified suppliers from Huawei and TSMC in the future, Chuangyuan Electronics will no longer sign new contracts with Huawei and TSMC, and will immediately change its business scope, in addition to continuing to fulfill the signed contracts. To sum up, the company has not obtained the qualifications of qualified suppliers from Huawei and TSMC, which has not caused any significant adverse impact on the company’s current business development, and the testing related products have been recognized by customers. However, if the company fails to obtain the qualifications of qualified suppliers in time or the access conditions of qualified suppliers change, it will have an adverse impact on the company’s future business development and operating performance.

Countermeasures: The company is actively communicating with Huawei and TSMC to apply for qualified supplier qualification.

Greece ningfu goddess theme SPA

Keywords: detoxification

Main raw materials: seawater and seaweed.

In Greek mythology, Nymph is the goddess in charge of the sea, lakes, springs and rivers. She lives in a silver cave at the bottom of the sea, with a beautiful voice and graceful dancing. She often soaks in seawater and has beautiful hair, smooth and flawless skin.

The Nymph-themed SPA takes care of the skin with the help of the rich resources and seaweed in the deep sea. Seawater is highly skin-friendly, can quickly penetrate into the inner layer of skin, deeply moisturize and activate skin, and enhance skin regeneration ability. Seaweed absorbs inorganic elements as nutrients every day, so it contains more natural inorganic elements than land plants, which can provide human needs, improve circulation, help the body detoxify and purify, replenish water and nourish.

Pure body and mind in blue sea water

The ocean foot bath containing marine microalgae appeared first. When your feet are gently immersed in the hot water mixed with lemon grass and green tea ingredients and light blue sea salt, it seems that your feet feel much relaxed at once, and the room is full of fresh and beautiful atmosphere of the sea. The micro algae from the Pacific Ocean make the next bath more relaxing and soothing. The natural Porphyridium and aloe essence contained in it can improve circulation, help the body to detoxify and purify, replenish water and nourish, and make the skin smoother. Being in it feels like floating on the blue water waves, and the sound of the waves lapping on the beach is lingering in my ears, so I can swim in the blue ocean to my heart’s content. This bath is especially suitable for people with poor sleep quality.

In order to further help skin exfoliate and detoxify, deep-sea white seaweed particles can be used to massage the body with lymphatic detoxification aromatherapy massage oil, which can stimulate lymphatic flow, detoxify and remove water, and reduce metabolic stagnation. The final nourishing and repairing body dressing is rich in spirulina essence, seaweed powder and soybean extract, which can effectively detoxify, improve edema, promote health, whiten and smooth skin, repair and resist aging, and nourish and moisturize.

During the whole nursing process, the room was very quiet except that the beautician occasionally asked softly about his feelings. The Indonesian massage used is different from the traditional Chinese acupressure acupoints. It uses more palm force and forearm force, and uses techniques such as palm strike, massage, kneading and reflection. The strength of each movement is just right, and each pressing place is a part that needs to be appeased urgently.

Cleopatra theme SPA

Keywords: anti-aging

Main raw materials: milk, pearls and honey.

Cleopatra Cleopatra is charming, glamorous and sexy. It is said that it was later discovered that Cleopatra bathed in milk on weekdays, scrubbed her body with sea salt, spread honey all over her body and face, and covered her face with gold foil every night, which eventually created a legend of immortality.

Pearl+milk+honey = young skin

The skin-beautifying effect of fresh milk bath has been described in the poem "Agar Jade Dew Wash and coagulate fat" as early as. And natural whitening and moisturizing milk+honey rich in vitamins+anti-aging holy pearl is a good combination of beautiful skin.

At this time, rose petals and long lemongrass floated in the white bathtub filled with warm water, and the beauty therapist slowly poured a can of milk and mixed it evenly. The room suddenly exudes a thick sweet smell, arousing the feeling of happiness from the heart. Gently pour a pool of flower water from the neck, shoulders, back and limbs … When taking a bath, soak the skin surface evenly in milk as far as possible, and gently massage it for 2~3 minutes, so that the nutrients in milk and pearl powder and honey can penetrate deep into the skin. When the skin is bathed in it, it will soon become tender, smooth, delicate, moist and whitening. This bubble bath is especially suitable for people with dry and dehydrated skin and mental fatigue.

It turns out that pearl milk can not only help skin exfoliate, but also relieve stress and relax. When used as body membrane, it can also lighten scars, improve skin color and make skin tender and smooth. During the process, the beauty therapist did not forget to remind that although milk is natural, safe and convenient, its effect is relatively short, and it can only stay on the skin surface, so it cannot completely replace other skin care products. In addition, milk contains high oil, so don’t forget to clean it before the end of nursing, so as to prevent clogging of pores and affect the normal function of the skin.

Can Cleopatra’s gold foil dressing really keep her face? Today, beauticians have improved it, using nano-pure gold combined with cytokines, active peptides, hydrolyzed silk protein and other ingredients to do facial care. After continuous use for one month, it has antioxidant, antibacterial and anti-inflammatory effects, stimulates self-renewal, makes skin shiny and transparent, and makes the feeling of firmness and brightness more obvious.

Thai royal herb

Health ball Massage

Keywords: anti-fatigue, relieving body ache

Main raw materials: a variety of herbs.

According to legend, this mysterious royal herbal secret recipe was only enjoyed by nobles in ancient times, and then it was gradually introduced to the people. It was found that the herbs used in it included tropical plants unique to Thailand, such as Casamona ginger, bergamot, lemon grass, tamarind fruit, derris, fennel, turmeric and white crane ganoderma lucidum. It makes use of the warm effect of hot-infiltrated herbal balls to penetrate the drug into the skin and supplement the energy elements belonging to the nursing part.

The refreshing effect of herbal balls

The massage technique in the process is quite unique. Massage important parts of the body with special aromatherapy oil. The beauty therapist uses the weight of his hands, arms, feet and his whole body, and uses unique methods such as pushing, pulling, stepping, pressing and pressing, and acts on muscle fascia and joints by pressing his feet, pressing his waist, stepping on his spine, and judo-style big back span, so as to relax muscles and bones, relieve stress and relax his mind.

The following hot herbal ball massage techniques are also very brilliant, especially the two hot herbal balls alternately act on the whole body skin, clicking, pressing, pushing, kneading or rotating, with various techniques. The beauty therapist will take turns to click and slide the herbal secret recipe health ball on the shoulder, neck, waist and other places that need to be comforted most. It is a little hot at first, but the skin will feel very comfortable after slowly adapting. Repeatedly several times, the herbal secret recipe health ball always keeps the appropriate temperature. Finally, the beautician will put the health ball on the waist and rub it back and forth. At this time, a hot air will be generated in the body, which can be kept for several hours.

Recently, MediaTek unveiled its new generation flagship 5G generative AI mobile chip Tianji 9300. The innovative all-core architecture design combined with the new generation AI processor APU and MediaTek’s unique cutting-edge technology, its powerful performance provided support for generative AI applications and created a vivid and substantial generative AI experience. At the same time, MediaTek shared resources with many AI companies in the industry, and jointly created an adequate AI ecosystem on the mobile side.

The brand-new seventh-generation AI processor APU 790 is born for generative AI.　　　　　

With the increasing demand of users for generative AI applications, the advantages of end-side generative AI such as convenience and security are highlighted. Of course, deploying the end-side AI language model requires strong AI computing power support.

Tianji 9300 is equipped with MediaTek’s seventh generation AI processor APU 790, which is designed for generative AI. It has a hardware-level generative AI engine, which can realize higher-speed and safer edge AI calculation, and deeply adapt to Transformer model for operator acceleration, with a speed eight times higher than that of the previous generation.

At the same time, the performance and energy efficiency of APU 790 have been significantly improved, and the integer operation and floating-point operation capabilities have been improved to twice that of the previous generation. Zurich ETHZv5.1 AI-Benchmark Mobile Soc scored 2109 points, and the AI performance successfully dominated the list, and the power consumption was reduced by 45%. With the support of powerful AI performance, images can be generated within 1 second. Tianji 9300′ s powerful AI computing power, innovative all-core CPU architecture and Immortalis-G720 GPU all lay a solid performance foundation for end-to-end running of generative AI.

At the same time, based on the characteristics of the large language model with hundreds of millions of parameters, MediaTek has developed the mixed-precision INT4 quantization technology, which, combined with the memory hardware compression technology of MediaTek, can make more efficient use of memory bandwidth, greatly reduce the terminal memory occupied by the large AI model, break through the memory limit of mobile phones for running the large AI language model end-to-end, and help the larger parameter model land on the end-side.

Based on the above, Tianqi 9300 landed a 7 billion-parameter AI language model on the side of vivo flagship mobile phone for the first time, with a processing speed of 20 Tokens per second. Not only that, MediaTek has broken through the industry limit, and has successfully run a large language model with 13 billion parameters on the end side with vivo. Even, Tianji 9300 has taken the lead in successfully running the AI language model with 33 billion parameters on mobile chips, leading the industry.

Tianji 9300 also supports multi-modal generative AI model, creating rich and interesting end-to-end experiences such as "Wen Sheng Poetry", "Wen Sheng Picture" and "Wen Sheng Interesting Picture".

It can be seen that Tianqi 9300′ s AI computing power and end-to-end generative AI capability are ahead of the industry, which is enough for users to be full of AI creativity anytime and anywhere.

The end-side skill expansion of generative AI model brings comprehensive and rich end-side generative AI experience.

Different from the cloud-side generative AI solution, due to the difference of hardware environment, the deployment of end-side generative AI also needs to consider factors such as mobile phone memory, storage capacity, and upper load limit. Therefore, MediaTek took the lead in proposing advanced solutions.

APU 790 supports NeuroPilot Fusion, an end-side skill expansion technology of generative AI model. It can continuously carry out LoRA (Low-Rank Adaptation) fusion on the end-side based on the basic big model. With the empowerment of hybrid AI, it can complete the fusion of n functions on the end-side based on one basic big model through cloud training, giving the basic big model more comprehensive and richer generative AI application capabilities.

For example, based on the "drawing GIF animation" function of the AI model end-side skill expansion technology, users can change different styles or even expressions according to a photo, and play an expression pack with a personal style, and the second expression pack is small.

NeuroPilot, an AI development platform, accelerates the end-side generative AI ecological layout.

Based on powerful AI computing power, advanced memory hardware compression technology and AI model end-side skill expansion technology, the APU 790 of Tianji 9300 has raised the speed and breadth of end-side generative AI to a new level. At the same time, in order to accelerate the deployment and popularization of generative AI in the end-side, MediaTek has also built a rich AI ecosystem with its AI development platform NeuroPilot, from the underlying hardware to the tool chain, model center and development ecosystem, helping the ecosystem to deploy end-side generative AI applications quickly and efficiently.

NeuroPilot, the AI development platform, supports leading-edge mainstream AI models such as Android, Meta LIama 2, Baidu ERNIE Bot Model and Hundred Rivers Intelligent Hundred Rivers Model.

More importantly, NeuroPilot has a complete and advanced tool chain, including low-rank adaptive fusion of NeuroPilot Compression, Speculative Decoding acceleration and model optimization and transformation technology.

MediaTek Tianji Developer Center can also provide one-stop developer resources for end-side generative AI landing, and share end-side model deployment cases to improve development efficiency. At present, more than 20 generative AI partners have joined the ecological co-construction.

MediaTek also works with industry contract partners to create a wonderful generative AI application experience. ArcSoft’s generative AI super-resolution technology is based on the edge computing power of Tianji 9300 APU, and its performance can be improved by 30% compared with the previous generation. When shooting at a magnification of 25 times, using the generative AI super-resolution technology, you can shoot more realistic image effects.

The generative AI semantic search technology of Extreme Sense Technology is also based on the edge computing ability of Tianji 9300 APU. Compared with the previous generation, the performance can be improved by 260%. For example, searching for photos in the photo album of a mobile phone and describing the content of the photos can accurately find the corresponding photos in milliseconds. Moreover, it can also be searched when the network is disconnected, and privacy will not be revealed.

Morpho’s video call real-time digital avatar generation technology is also based on the edge computing ability of Tianji 9300 APU, and its performance is improved by 26% compared with the previous generation. The general virtual portrait generator needs to manually select the appearance style, which takes time. However, based on the video call real-time digital avatar generation technology, the user can operate easily, and the digital avatar can be generated instantly only by opening a single frame of the camera.

Based on the edge computing ability of Tianji 9300 APU, the performance of Hui carp’s generative AI anti-glare technology can be improved by 60%. With the help of this technology, whether outdoors or indoors, if there is glare when shooting, you can eliminate glare interference as long as you relax and darken it.

It can be seen that under the trend of AI-side cloud convergence, Tianqi 9300 has shown comprehensive advantages in AI computing power, generative AI user experience and ecology, setting a new benchmark for a new generation of flagship end-to-end generative AI experience, and powerful generative AI will use Tianqi.

In addition, MediaTek and other pioneers of generative AI are constantly carrying out technological innovation and ecological layout, vigorously promoting hybrid AI computing, providing a unique and efficient solution for end-to-end generative AI deployment, and devoting themselves to promoting the widespread application of generative AI at the end-side, so that more users can experience personalized end-to-end AI applications and build a new panoramic intelligent experience, thus enabling technology to better serve the public.

　

Dancing, reading, fitness … Here, everyone can always find their own interesting activities, and walk into the "Neighborhood Home" activity center for the elderly at No.1 Yintian Changxing Lake, Changxing Community, Guankou Street, Liuyang City. It is a "base" for residents’ activities and a "conference hall" for residents to make suggestions and suggestions.

On April 26th, the "Good Neighborhood House" was officially unveiled with the cheers of everyone. Combined with local conditions, the street adheres to the way of party building leading, government leading and social participation, and builds the "Neighbourhood House" of Yintian Changxing Lake No.1, which realizes the construction of leisure activities venues integrating table tennis room, chess room, reading room and conference hall, and also provides services such as rest, drinking water and emergency charging to meet the diversified service needs of residents. At the same time, we will set up functional areas such as "Hello Neighbor Neighborhood Council" and Neighborhood Pioneer Post, extend the service "tentacles" of the Party organization from the general branch of the community to the districts and communities, and build red positions around the residents to realize community governance and residents’ service at the same frequency.

At the beginning of the construction, the general party branch of the community took the lead, with the participation of the community party branch, the industry committee, the property company, the members of the volunteer service team and the neighbors. Relying on the red platform of the community, the opinions of the masses were fully collected, and the residents’ representatives were mobilized to hold a good-neighborly meeting. After many discussions, it was finally unanimously decided that the community party branch would take the lead, the industry committee would raise funds, and the elderly association would assist in the management, so as to build a "good-neighborly house" of about 400 square meters on the eight overhead floors of the community. Really make "small things about people’s livelihood" a major event of "benefiting the people and benefiting the people".

At the opening ceremony of the Good Neighborhood House, the neighbors got together, singing and dancing. Accompanied by cheerful music, the performance kicked off in the opening dance of "Gathering Together". The dance "I Love Beautiful China" and other programs fully demonstrated the vitality and spiritual outlook of residents, and condensed and conveyed the positive energy among neighbors.

"Now, we have our own activity center. I dance when the weather is fine, and play chess and ball games when it rains. It’s really good …" Liu Yi, 58, said happily, waving a ping-pong bat, "Neighborhood House" has built a communication platform for residents, which has brought neighborhood relations closer, enhanced neighborhood feelings and further enhanced the sense of belonging and happiness of community residents.

Complete convenience service facilities, comfortable chairs and sofas, neatly arranged books … This warm and diverse neighborhood space closely revolves around the working idea of "co-construction, co-governance and sharing", and strives to extend services to people’s doorsteps and send warmth to people’s hearts.

In recent years, Guankou Street has actively built a "good neighbor’s house" activity position, and carried out neighborhood cultural activities in a normal way, so that "strangers" become "friends" and "friends" become "relatives". In the next step, Guankou Street will be guided by residents’ needs and rely on the "Good Neighborhood House" to carry out a variety of neighborhood activities to create a "happy life circle" with more family flavor and human touch.

　　Mp3 is still here today, not the player of that year. The author’s impression of mp3 players began in high school. At that time, I was still using a heavy tape walkman, but "wearing headphones and hanging an mp3 player around my neck" has quietly become a campus fashion. At that time, the mp3 player was relatively large, connected with wired headphones, and looked from a distance, as if a stethoscope was hung around his neck.

　　At that time, I was lucky enough to experience my roommate’s mp3 player. It was very convenient to listen to songs, but it was inconvenient to find songs. The playing modes were only sequential playing, random playing and single loop. As an expert in using the rewind button of the walkman, I can judge the position and rewind time of a song according to the diameter of the tape reel, so the mp3 player is really "hehe" in my eyes.

　　Unfortunately, the good times didn’t last long. As soon as I graduated from high school, digital products such as walkman and tape were swept into the history museum along with the "rewind skills" that the author was proud of. But they were not killed by mp3 players, but by more advanced mobile phones. When I was in college, I used a mobile phone called "Nokia". Now children may not have heard of this brand. Back in those days, Nokia dominated the mobile phone industry with its Symbian intelligent system. It could not only listen to mp3 music, but also watch movies on a 2: 00-inch screen. Of course, more importantly, it saved money on mp3 and mp4 players.

　　However, the author’s college roommate Z still keeps the habit of using mp3 player. His mp3 player is a famous brand product in Japan, which costs thousands of dollars. It is said that the sound quality is excellent when used with a pair of German brand headphones costing more than 300 yuan. I’ve listened to it, too, and it’s really good, but if it’s too good to be wanted, it’s not too bad.

　　This Z student not only has an mp3 player, but also an mp4 player with a bigger screen than his face, which is the originator of the current big-screen mobile phone. At that time, I thought that it was just around the corner for mobile phones to replace mp3 and mp4 players, and the practice of Z students could only be simply evaluated as rich and powerful.

　　However, classmate Z gave me an unexpected answer. He said: "the computer is very powerful, right? But every time I turn on the computer, I always change my original intention unconsciously. For example, I originally wanted to watch a movie, but I played a game." I wanted to listen to music, but I got online. So I think that computers are used to play games online, mp4 players are used to watch movies, and mp3 players are used to listen to music. "

　　Some people may say that this is your classmate Z’s poor self-control. But just imagine, if you were given a computer with Internet access and full of movies, music and games to learn English, how long would you last without external supervision?

　　Once upon a time, the author was superstitious about self-control, but if we contact the supervision mechanism, we will find that in a relaxed environment, facing a world full of temptations, people basically have no self-control, and the probability of getting lost or even sinking is extremely high.

　　"The keyboard starts and ends, and you know exactly that 88 keys are there. You can’t go wrong … I like it, and I can easily cope with it … in that infinite spreading city, everything is there, but there is no end, no end at all. What I can’t see is the end of all this, the end of the world. " At the end of the movie legend of 1900, the hero 1900 uttered such a sigh.

　　I don’t know how many netizens have had similar ideas to 1900 when facing computers and mobile phones. Or perhaps, many netizens have lost themselves in the abyss of network information and forgotten the original intention of using computers and mobile phones before they have time to express their feelings.

　　Many years later, when I bought a certain brand of electronic paper book reader, I remembered the classmate who listened to music with mp3 player in college. Someone asked me: Why spend more than 800 yuan to buy a digital product that is slow to respond and can only read books?

　　To this, I can only answer: because my self-control is too poor.

　　As the saying goes, "a thousand dollars can’t buy old people to lose weight." Nowadays, many old people have joined the army to lose weight, and it seems that they will be healthy if they lose weight. Recently, a study published in the American Obesity magazine shows that the elderly’s deliberate weight loss may affect their bone health.

　　Body mass index BMI= the square of weight/height, which is an accepted standard to measure obesity. In this study, 77 students with an average BMI of 33.6 (usually 18.5≤ BMI index ≤ 23.9 old people with normal weight, more than 29.9 are severely obese) were given weight-loss intervention for 18 months, and the overall weight of the old people and the bone mineral density of the areas (total hip, femoral neck, lumbar vertebrae and trabecular bone) were monitored and scored at 18 months and 30 months. The results show that the decline of hip bone mineral density will last for one year after weight-loss intervention for elderly obese patients, whether they rebound or not. The study also found that fat loss and weight loss reduced the bone mineral density of hip and increased the risk of osteoporosis.

　　Gou Bo, a professor in the Department of Health Sciences of Xi ‘an Institute of Physical Education, said that if the elderly lose weight improperly, such as excessive diet control, resulting in insufficient nutrition intake, or lose weight too much and too fast, resulting in significant weight loss, it will lead to a decline in bone density. Older people do not have to lose weight if they are only slightly obese and have no obvious cardiovascular disease. If there are some contraindications to exercise, and it is not suitable for exercise to lose weight, you can seek nutrition, medical care and other methods to control your weight under the guidance of a doctor. If obesity is accompanied by other chronic diseases, lose some weight appropriately. In principle, adopt safe and effective methods to achieve the goal at a slower speed such as diet control and exercise.

　　Many old people find that even if they eat and exercise as much as when they were young, it is easy to "gain weight". The reason is that the basal metabolic rate and muscle mass of adults decrease year by year with age. Therefore, even if the elderly eat less, their digestion and absorption ability are poor, and the balance of energy in and out is still "less in and out", in which case it will be "fat".

　　Gou Bo emphasized that obesity will directly affect heart function and vascular health, and it is easy to suffer from various cardiovascular and cerebrovascular diseases. The ideal situation is to "gain muscle and lose fat" on the premise of ensuring basic nutrition.

　　Old people can’t take extreme measures to lose weight, let alone go on a diet like young people. We can start with the moderation and choice of dinner, eat some coarse grains instead of staple food, eat food with high protein content for breakfast, and control the staple food at about 2 Liang at noon. It is not recommended to choose diet pills or surgery to lose weight.

　　In sports, it is suggested that aerobic exercise should be combined with strength training, and it is best to take some soothing forms, such as Tai Ji Chuan, yoga, walking, etc. As long as you can persist every day and achieve a certain amount of exercise, you can lose weight completely.

Dr. Guan Kang Kang You from the Department of Nuclear Medicine talks about thyroid gland.

1. What is pepsinogen?

Pepsinogen (PG) is the precursor of pepsin. According to its biochemical properties and immunogenicity, it can be divided into two subgroups. The immunogenicity of 1~5 components is the same, and it is called Pepsinogen I (PG I), which is mainly secreted by the main cells of gastric fundus gland and mucus neck cells. Components 6 and 7 are called pepsinogen Ⅱ(PGⅡ), which can be secreted by the main cells and mucus neck cells of gastric fundus gland, and also produced by mucus neck cells of pyloric gland of cardiac gland and gastric antrum and upper duodenum.

Usually, about 1% PG enters the blood circulation through the capillary of gastric mucosa, and the PG entering the blood circulation is very stable in the blood. Serum PG ⅰ and PG ⅱ reflect the number of glands and cells in gastric mucosa, and indirectly reflect the secretory function of different parts of gastric mucosa. When pathological changes occur in gastric mucosa, the content of serum PG also changes. Therefore, monitoring the concentration of PG in serum can be used as a means to monitor the status of gastric mucosa.

Detection of pepsinogen (PG), an early warning indicator of gastric cancer

1. Chronic atrophic gastritis is an important "transitional event" in gastric mucosa canceration.

Gastric cancer is one of the common malignant tumors in China, and its mortality ranks first among all kinds of malignant tumors. Its early diagnosis and early treatment have become the only way to improve the quality of life of patients and reduce the mortality. At present, the main methods for diagnosing gastric cancer are fiberoptic gastroscopy and upper gastrointestinal radiography, among which gastroscopy is called the "gold standard" for diagnosing gastric cancer.

At present, it is believed that partial atrophy can be reversed, and once it enters intestinal metaplasia, it is difficult to reverse it. Therefore, there is an urgent need for a tool that can keenly detect the atrophy of gastric mucosa. At this time, the detection of pepsinogen plays a powerful role.

When the gastric fundus gland atrophied, the number of main cells decreased and the level of PG ⅰ decreased. However, because there are more cells secreting PG ⅱ, PG ⅱ can still maintain a high level at this time, and the ratio of PG ⅰ to PG ⅱ decreased significantly. When atrophic gastritis is accompanied by intestinal metaplasia and gastric antrum gland extends to the stomach body, and pseudopyloric metaplasia of gastric fundus gland occurs, the level of PG ⅱ increases more, and the ratio of PG ⅰ to PG ⅱ decreases further. Therefore, the decrease of PG ⅰ level is a reliable sign of gastric fundus gland mucosa atrophy, and PG ⅰ/PG ⅱ profile reflects the degree of gastric fundus gland mucosa atrophy.

2. Helicobacter pylori infection is the initiating factor for the development of gastric cancer.

The occurrence of gastric cancer is the result of multiple factors. The multi-step hypothesis of gastric cancer, that is, from chronic non-atrophic gastritis (formerly known as chronic superficial gastritis) → atrophic gastritis → intestinal metaplasia → intraepithelial neoplasia (formerly known as dysplasia) → gastric cancer, has been generally accepted. Helicobacter pylori (Hp) infection has become the most important initiating factor, and Hp infection has been recognized as an independent risk factor for gastric cancer.

Therefore, active detection of Hp has become one of the important measures to prevent and treat gastric cancer. Hp detection is mainly divided into invasive and non-invasive methods. For Hp-positive infected people, the major guidelines have reached a consensus that Hp infection-related gastritis is an infectious disease and it is recommended to eradicate it.

Hp infection can also significantly affect the serum PG level. At the beginning, PG ⅰ and PG ⅱ both increased, and the increase of PG ⅱ was faster, then PG ⅰ/PG ⅱ decreased, and the larger the Hp infection focus, the greater the decrease of PG ⅰ/PG ⅱ. However, the results of pepsinogen test are lack of specificity, and special Hp test is still needed to judge whether Hp is infected or not.

Third, pepsinogen Ⅰ(PGⅠ),

The results of pepsinogen Ⅱ(PGⅡ) were analyzed as follows:

Four, "pepsinogen" test results misunderstanding:

Myth # 1: If only PG ⅰ is measured during physical examination, nearly 70% of the results are in the range of 40~70ng/mL, which seems to be lower than 70ng/mL on the surface, and gastric atrophy is suspected, but the results are difficult to explain because PG ⅱ and ratio are not measured. When PGⅡ is retested, the ratio of more than 90% is greater than 3. This kind of situation is due to the high incidence of chronic superficial gastritis in China population, which belongs to normal physiological gastric acid secretion insufficiency.

Myth 2: PG-positive means "stomach cancer theory": positive means people at high risk of stomach cancer. PG project is a simple screening project for gastric cancer in the early stage of physical examination, replacing X-ray and ultrasonic screening for gastric cancer. The main significance lies not in diagnosis but in early detection and prevention. Normal people are 15%PG positive, and those with PG positive have a high risk of developing gastric cancer, and the early detection rate of gastric cancer is 1%~2%.

Myth # 3: Pay attention to the change of reference range values of PG ⅰ and PG ⅱ, but not the ratio. Because the secretion of PG ⅰ in gastric mucosa changes greatly (above 70~800ng/mL) under the attack of inflammation, the secretion of PG ⅱ is relatively constant. When comparative value > 3, the degree of PG ⅰ increase can only be combined with clinical analysis to determine the type of gastric diseases. When comparative value < 3, it is suggested that further in-depth endoscopy or pathological sampling should be taken to confirm and warn the high risk of early gastric cancer, and follow-up monitoring should be carried out in the last five years. The incidence of gastric cancer was 2% in PG-positive patients who had no gastric cancer in the same year and in the following five years.

Five, Japan’s experience for reference ("ABC" method+endoscopic screening)

Our neighbor Japan, as a country with high incidence of gastric cancer, has done a very good job in early cancer screening. Their screening strategy for early cancer firmly grasps the two controllable factors of Hp infection and whether gastric fundus gland atrophy occurs.

The Kyoto Consensus of Japan made the following recommendations for the national early cancer screening strategy: first, for Hp infection, the Kyoto Consensus emphasized "shoot to kill", and after everyone sterilized and eradicated Hp, PG was evaluated. The ratio of PG ⅰ/PG ⅱ is ≤3.0, which is regarded as the critical diagnostic value of atrophic gastritis, and as the screening standard of high-risk population of gastric cancer.

Vi. A Long Way to Go-Strategies for Early Cancer Screening in China;

China has a large population base and the incidence of gastric cancer remains high, so it is imperative to find a simple, accurate and effective screening method for gastric cancer. In 2017, the China Consensus on Chronic Gastritis highly affirmed the value of PG, and the guidelines gave the following recommendations: The detection of serum pepsinogen (PG) ⅰ and ⅱ and gastrin -17 may help to judge whether there is gastric mucosal atrophy and its degree. Detection of serum PG ⅰ, PG ⅱ, PG ⅰ/PG ⅱ ratio combined with anti-Hp antibody is helpful for risk stratification management.

The Expert Consensus on Early Gastric Cancer Screening Process in China, published at the end of 2017, not only affirmed the value of serum PG, but also put forward a new gastric cancer screening scoring system, in which the elderly, male, Hp antibody positive, low pepsinogen ratio (PGR) and high serum 17(gastrin-17 (G-17) level are high risk factors for gastric cancer.

Among them, G-17 is a new item in China Guide. G-17 is an amidated gastrin synthesized and secreted by G cells in gastric antrum. Its main physiological function is to stimulate gastric acid secretion and promote the proliferation and differentiation of gastric mucosal cells. G-17 is one of the sensitive indexes to reflect the endocrine function of gastric antrum, which can indicate the atrophy of gastric antrum mucosa or whether there is abnormal proliferation. G-17 itself can also promote the occurrence and development of gastric cancer. When the serum G-17 level rises, it may indicate the risk of gastric cancer.

In addition, different from the Kyoto consensus, the consensus in China put forward the critical value of serological detection for the first time, that is, when PGR<3.89 and G-17> 1.50pmol/L, the risk of gastric cancer increased significantly. The critical value of PGR defined by Kyoto Consensus is ≤3.

According to the score, the guide divides the population into three groups: low risk, medium risk and high risk, and gives the screening strategy.

At the same time, however, we should also see the shortcomings of the China guidelines. The screening population is over 40 years old, and there are other risk factors such as high incidence area of gastric cancer, Hp infection, previous precancerous diseases of gastric cancer, first-degree relatives of gastric cancer patients, diet and so on. However, at present, the onset age of gastric cancer is getting earlier and earlier, and I believe it will definitely enter prospecting stage in the future.

To sum up, serum PG combined with Hp detection is helpful to evaluate the risk of gastric cancer, and can be used as a routine screening method for gastric cancer for ordinary people. However, it cannot replace gastroscopy, and gastroscopy is still strongly recommended for high-risk groups.

　　Cctv newsOn January 19th, the joint prevention and control mechanism of the State Council held a press conference on epidemic prevention and control during the Spring Festival.

　　At the meeting, a reporter asked whether people who have not yet been infected with Covid-19 can safely return home for the New Year. What are the suggestions on protection? Do people who have recently been infected with Covid-19 still need protection when traveling?

　　Chang Zhaorui, a researcher at the Center for Disease Control and Prevention of China, said that people are generally susceptible to Covid-19. Some people who have not been infected do not rule out the influence of travel fatigue and frequent contacts during the Spring Festival, and the risk of infection will increase. It is suggested that relevant personnel should continue to do personal protection, keep regular work and rest, eat reasonably, exercise moderately, disinfect well and wear masks. The public who have been infected with Covid-19 should continue to do personal protection to prevent infection of other respiratory infectious diseases, including influenza.

Ashton Kutcher, the American movie star who plays Jobs, has just joined Lenovo Group. According to the USA-Today website, Kucher signed a cooperation agreement with Lenovo on the evening of 29th local time to serve as Lenovo’s product engineer and spokesperson.

Lenovo held a new product launch conference in Los Angeles at 7 o’clock that night, and launched the world’s first "legged" tablet computer &mdash; &mdash; Yoga tablet. The conference was broadcast live on Youtube for global users to watch. At the press conference, Kucher held a Yoga tablet computer, just like the way Jobs introduced Apple’s new products. After the conference, Kucher will meet Lenovo engineers and executives in China in the future.

Kucher introduces Lenovo Yoga tablet computer.

Kucher said at the press conference that modern people often encounter two situations in their daily lives: lying in bed and using a tablet computer is easy to slip into their face because of their hands; The battery of a tablet or smart phone is useless, so everyone has to bring a brick-like mobile power supply. These two common details made the audience laugh, which is indeed an experience that many people have had. The new products launched by Lenovo just solved these two problems: the small bracket liberated people’s hands; The battery life that can work continuously for 18 hours on a single charge can help people reduce the weight of their backpacks. In addition, you can also charge your smartphone with a tablet computer, and the USB interface on the tablet computer can easily achieve this.

Lenovo’s new tablet has 8-inch and 10-inch versions, and the price is $249 and $299 respectively. These two products will be available from October 30, just in time to "play against Taiwan" with the Apple tablet iPad Air, which was officially released on November 1. However, Lenovo’s products are much cheaper than Apple’s iPad Air, and the lowest price of the new generation iPad is $499.

Kucher, 35, graduated from the University of Iowa in the United States, majoring in biochemical engineering (but didn’t graduate). She was once kicked out of her dormitory because she was too noisy and crazy. However, he is now Walden Schmidt, the hero of the popular comedy Two and a Half Heroes, which was launched by CBS in the United States, and also a famous angel investor in Silicon Valley. In addition to Skype, Kucher’s investment also includes Foursquare, Flipboard and Path.

Kucher at the new product launch is very much like Jobs.

Kucher has also cooperated with Google and Apple. When talking about why he joined Lenovo, Kucher said, "Lenovo’s hardware is very, very good. I want to make their products as consumer-friendly as possible. " Kucher will make suggestions on the design and software of Yoga tablet.

USA-Today said that this cooperation is a prepared risk for both sides. And Kucher said that this is precisely the reason why he joined Lenovo. "If you look back on my career, you will find that I have always liked adventure &mdash; &mdash; Lenovo, too, "Kucher said.

Phoenix. com said that some fruit fans commented that Kucher had joined Lenovo: He should know more about Apple culture after playing Jobs, and now it’s a bit disappointing to advertise Lenovo for money. It seems that he is not a real fruit fan. Since he is not a fruit fan, no wonder he can’t play Jobs well.

Lenovo and Kucher did not disclose the salary of this cooperation.

Stills of the movie Jobs

Liam Neeson talks to the mystery man with a serious face.

1905 movie network news A few days ago, the action suspense film has met the audience in North America. The action scenes of life and death and the suspense reversal of wits have made the film gain excellent box office results and word of mouth after its release. With a series of films, liam neeson, who successfully created the screen to "rescue professional households", once again "returned to his old job". As an ordinary white-collar uncle, he was not only accidentally involved in a conspiracy, but also single-handedly searched for a mysterious passenger on the commuter train in new york and eliminated the danger, which was exciting and suspenseful.

The Commuter tells the story of Macaulay, the hero played by liam neeson, who meets the mysterious girl Joanna on his way home by commuter train in new york. Joanna offered Macaulay a tempting task &mdash; &mdash; Find out a passenger in the car and get a huge sum of cash in return. But in the process of searching, Macaulay gradually found himself not only involved in a deadly conspiracy, but also unable to quit, and a rescue operation full of suspense and excitement began. When the commuter train close to everyone’s life scene becomes a runaway and deadly journey, how Uncle Liam can solve the puzzles lurking in the commuter train and rescue the passengers is expected.

Liam Neeson turned into a white-collar uncle, running for his life.

With a series of screen roles to rescue relatives in distress, liam neeson deserves to be a "rescue specialist" in Hollywood. In Taken3 series films, he plays a retired agent who chases across many countries and rescues his daughter and wife from foreign evil organizations. Whether it is a sharp and professional lynching trial or a quick skill of one enemy and ten, the image of a loving father who is eager to save a woman and the fierce domineering of fighting violence with violence have made him numerous; In the movie, liam neeson, who plays the plainclothes air marshal, changed the battlefield again, fighting wits and wits with the hijackers lurking among the passengers at high altitude, reversing Gan Kun in the air at the peak of 10,000 meters, finding out the black hand behind the scenes from the clues, and at the same time, fighting hand-to-hand in the narrow cabin to rescue the passengers of the whole plane &hellip; &hellip;

It can be said that with a series of invincible rescue operations, Uncle Liam not only successfully created an IP movie with the theme of "rescue", but also made himself a leading figure in Hollywood action heroes and won fans all over the world to call him crazy.Different from films such as Taken3 and NON-STOP, the role played by liam neeson in The Commuter no longer has the aura of skills such as special agent and air marshal, but becomes a white-collar office worker. Playing an ordinary person in an action movie for the first time, he not only had to make a living, but also struggled with the complicated and demanding needs of his boss and customers. At the age of 60, he lost his job and lost his direction in life, and he didn’t know how to face his family and future. It is a challenge for talented liam neeson to play such an ordinary middle-aged man who is involved in a life-and-death rescue operation at the same time. In the film, liam neeson, who was laid off, was lured by the mysterious girl into a gambling conspiracy because of the pressure of life.

Liam neeson moved the wrench to rescue the commuter train.

Jaume serra, the director who has cooperated with liam neeson for four times, praised Uncle Liam’s performance. He recalled his experience in shooting The Commuter, saying, "Every day when shooting, I am like a child looking forward to a Christmas present, waiting for the performance surprise brought by Nelson. His style and his eyes, he can completely change and create new roles with various nuances."

Not only is it more interesting in acting, but the action scene of the film is also thrilling. In the closed tense and high-speed train space, liam neeson should not only race against time to crack the true identity of the man behind the scenes, but also use all props in the train to fight, constantly resolve the dangerous ambushes and rescue the passengers on the train. The gradual reversal of the plot and the rapid and sharp action scenes have all upgraded The Commuter’s performance and action scenes.

In addition to liam neeson, the film The Commuter also featured famous Hollywood movie stars Vera Farmiga, Patrick Wilson and sam neill, and was directed by NON-STOP’s Hollywood genius jaume serra. The film has been released in North America and is expected to be introduced to Chinese mainland in 2018.
