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, answered a reporter's question on whether the PLA would conduct exercises.

Soldiers have no constant potential and water is impermanent. Whether and when to hold the exercise is up to us to decide independently according to our own needs and the struggle situation. No matter whether the exercise is held or not, the PLA will not be absent or soft in fighting for "independence" and promoting reunification. Any act of "seeking independence by relying on foreign countries" and "seeking independence by force" will be severely punished and doomed to failure.

Shenzhen accelerates to build a new generation of world-class automobile cities. The total output of automobiles this year is expected to exceed 2.8 million.

(Shenzhen Special Zone Daily)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 30-year Treasury ETF rose sharply at the opening, hitting a record high.
