Guosheng Securities: AEC heavy-duty computing industry chain has entered the era of Lian Heng. Guosheng Securities Research Report pointed out that AEC(Active Electrical Cable) is an active cable interconnection scheme, which is mainly used in short-distance high-speed data transmission scenarios in data centers. 1)AEC is expected to become the first step for optical module manufacturers to penetrate downwards. Optical modules need to master photoelectric conversion and high-speed data communication, and DAC/AEC/AOC products have relatively mature technical requirements compared with single-mode/multimode optical module products with longer transmission distance. 2) Copper interconnection is widely used by large CSP not only in NVIDIA. NVIDIA used a large number of high-density copper interconnects in B series products, which made the industry re-recognize the reliability and price advantage of copper interconnects in short-distance scenes. 3) In the era of Lian Heng, domestic manufacturers still have obvious advantages. Chip manufacturers, represented by NVIDIA, have been hoping to conduct a comprehensive industry consolidation and provide customers with a complete set of solutions. What CSP manufacturers want more is the decoupling of the industrial chain, and every link such as GPU, copper connection, optical module and switch can find corresponding suppliers. The heavy volume of AEC and the rise of CSP manufacturer's independent scheme indicate that the computing power industry chain has entered the era of Lian Heng, and we are firmly optimistic about the domestic related computing power industry chain.The weighted share price index of Taiwan Stock Exchange opened 0.2% lower at 23,002.37.Google reached a strategic cooperation with domestic consumer-grade AR glasses manufacturer XREAL.

Ministry of National Defense: Sun Tzu's Art of War belongs to both China and the world. On the morning of December 13th, Senior Colonel Wu Qian, director of the Information Bureau of the Ministry of National Defense and spokesman of the Ministry of National Defense, released a message on the recent military-related issues. Reporter: It is reported that the 10th International Symposium on the Art of War was held in Beijing, which aroused widespread concern at home and abroad. Please tell us more about the situation. Wu Qian: On December 5-6, the 10th International Symposium on Sun Tzu's Art of War was held in Beijing. More than 350 Chinese and foreign experts and scholars from nearly 30 countries conducted in-depth discussions on the theme of "Sun Tzu's Art of War and Mutual Learning of Civilizations" and achieved positive results. Sun Tzu's Art of War is not only China's, but also the world's. It not only shows the mystery of the Art of War, but also embodies the dialectical thought. The ideas contained in it, such as "stopping fighting for military power", helping each other in the same boat, knowing ourselves and preparing for victory, have already surpassed the scope of the country and become the common wealth of human civilization. Since ancient times, knowing soldiers is not bellicose. Studying Sun Tzu's art of war is not to follow the ancient times, but to learn from the present. Today's world should not be an arena where you lose and I win, but a garden where civilizations learn from each other. We are willing to take Sun Tzu's art of war as a bridge, study and discuss the way of peaceful development that transcends barriers through communication, conflicts through mutual learning and superiority through equality, actively practice the concept of community of human destiny, and contribute to the great integration and development of human civilization.Maotai Group had an exchange discussion with Huawei.
