In the government and enterprise market, the company's government and enterprise customers reached 15.53 million, a year-on-year increase of 37.56%; in emerging markets, the company expanded new development space for information services, focusing on international business, digital content, and mobile payments and other emerging areas.

On December 27, 2021, China Mobile disclosed an announcement on the results of the initial public offering of shares. The unpaid subscription amount of online investors was 743 million yuan, setting a record for the highest abandonment of A shares.

At 12:12 on December 7, the Ceres-1 Yao-2 carrier rocket was successfully launched from my country’s Jiuquan Satellite Launch Center. Five small satellites including Bauhinia-1 and 03 satellites were successfully sent into the scheduled orbit, and the launch mission was a complete success.

This mission is the second flight of the Ceres-1 carrier rocket.

The Ceres-1 launch vehicle is a small solid commercial launch vehicle developed by Beijing Galaxy Power Equipment Technology Co., Ltd., which can meet the launch requirements of low-Earth orbit micro-satellites.

On December 2nd, according to Tech Planet report, Tencent recently launched a new social app "doX". doX is a social platform designed for young people.

doX focuses on social networking with short video content. By shooting interesting short video content, you can meet like-minded friends on the platform.

Currently, doX is still in the testing stage, and users need a password to enter doX.

According to reports, the content page layout of doX is similar to that of Instagram. Users can watch short video content sent by other users in the App, and send messages to the author.

doX also supports users to shoot short videos and provides an "inspiration library" to assist video shooters in their creation.

The short video social track has been relatively hot in recent years. At present, many domestic manufacturers have participated in it. For example, ByteDance has launched "Multi-Flash", Kuaishou has launched "One Sweet Face Chat", Momo has launched "Eye", and Tencent "Maohu" has also been introduced before.

According to news on November 29, according to the official website of the Chinese Academy of Sciences, recently, the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences developed a large-scale laser communication calibration equipment for Beidou Global System to complete the satellite-to-ground high-speed downlink laser communication test.

The equipment has completed various test contents for the high-orbit and medium-orbit satellite terminals, and has realized the two-way tracking of beacons and signals, adaptive correction, uplink and downlink communication, and calibration of the satellite terminal parameters.

Because laser communication has the advantages of high speed and high confidentiality, it has become one of the important technical means in satellite data relay, high-speed data transmission, and satellite communication networks. Large-aperture laser communication calibration equipment is a must in laser communication networks. Device.

According to reports, the Beidou laser communication calibration ground equipment is the first time that Changchun Institute of Optics and Mechanics has applied adaptive technology to the field of satellite-to-ground laser communication. The wavefront correction accuracy is better than λ/8 (λ=1550nm), and the coupling efficiency before and after correction has been greatly improved. , Under the conditions of urban atmospheric turbulence, the satellite-to-ground downlink coherent optical communication is realized. The device can be used in vehicles to facilitate the deployment of mobile stations. Its first test has realized the second communication of coarse tracking between satellites in the same high orbit on the ground.

At present, Beidou laser communication standard calibration ground equipment has completed many test tasks of ground-to-medium orbit satellites and high-orbit satellites.

President Xi Jinping held a video meeting with US President Biden on the morning of November 16. The two sides conducted full and in-depth communication and exchanges on strategic, overall, and fundamental issues related to the development of Sino-US relations, as well as important issues of common concern.

Xi Jinping expounded China's principled position on the Taiwan issue. Xi Jinping emphasized that the situation in the Taiwan Strait is facing a new round of tension because the Taiwan authorities have repeatedly attempted to "rely on the United States for independence," and some people in the United States intend to "use Taiwan to control China." This trend is very dangerous. It is playing with fire, and playing with fire must burn oneself. The one-China principle and the three Sino-US joint communiqués are the political foundation of Sino-US relations. Successive U.S. governments have made clear commitments to this. The true status quo of the Taiwan issue and the core content of one China are: there is only one China in the world, Taiwan is a part of China, and the government of the People's Republic of China is the sole legal government representing China. The complete reunification of China is the common aspiration of all Chinese people. We are patient and we are willing to use our utmost sincerity and do our utmost to strive for the prospect of peaceful reunification. However, if the "Taiwan independence" separatist forces provoke persecution, or even break through the red line, we will have to take decisive measures.

Biden said that the US-China relationship is the most important bilateral relationship in the world. As two world powers, the United States and China have responsibilities to both the United States and China and the people of the world. The two sides should increase their understanding of each other's intentions through open and frank dialogue, and ensure that the competition between the two countries is fair and healthy, and will not evolve into conflict. I agree with President Xi Jinping's statement that history is fair, and US-China relations can only be done well, not messed up. China was already a big country more than 5,000 years ago. I would like to reiterate clearly that the United States does not seek to change China’s system, does not seek to strengthen alliances against China, and has no intention of conflict with China. The US government is committed to pursuing the long-term consistent one-China policy, does not support "Taiwan independence," and hopes that the Taiwan Strait will maintain peace and stability. The United States is willing to work with China to respect each other, coexist peacefully, strengthen communication, reduce misunderstandings, properly handle differences in a constructive way, strengthen cooperation in areas where the interests of the United States and China are the same, and jointly respond to global challenges such as new crown pneumonia and climate change. The people of the country can live a better life. Our younger generation should be encouraged to get in touch with each other more and understand each other's cultures, so as to make the world a better place.

The two sides also exchanged views on Afghanistan, the Iranian nuclear issue and the situation on the Korean Peninsula and other international and regional issues of common concern.

The capitals of the two countries believe that the meeting was frank, constructive, substantive, and fruitful, which is conducive to enhancing mutual understanding between the two sides, increasing the positive expectations of the international community on Sino-US relations, and sending a strong message to China, the United States and the world. Strong signal. The two sides agreed to continue to maintain close ties through various means to push China-U.S. relations back on the right track of healthy and stable development, and benefit the peoples of China and the U.S. and the peoples of the world.
