Briefly describe the establishment and development of the Chinese People's Navy.

The establishment of the Chinese People's Navy can be traced back to the early 20th century. At that time, China was still in a semi-colonial and semi-feudal society, and its navy was very weak, with only some self-defense forces. With the gradual development of the country, the people of China began to realize the importance of maritime rights and interests. 1In September, 924, the Chinese Red Army of Workers and Peasants established the first red naval force with the assistance of the Red Guards in Nanchang, Jiangxi. Its main task is to destroy the enemy's maritime strongholds and cover the ship transportation in the Soviet area. 1949, People's Republic of China (PRC) was founded and the Chinese People's Navy was formally established. Since then, the navy has gradually developed and expanded, and has successively set up several fleets, such as the North Sea Fleet, the East China Sea Fleet and the South China Sea Fleet, realizing the transformation from no strength to gradually catching up with or even leading other navies. In 1970s, China began to reform and open to the outside world, and the navy also carried out reforms, focusing on technological innovation and modernization. During the period of 1990, China navy began to go to sea, actively participated in international peacekeeping and humanitarian relief operations, and improved its international status and influence. Since the 20th century, China Navy has continuously strengthened its modernization, introduced advanced technology and equipment, improved its maritime defense capability and combat capability, and become a powerful navy moving towards deep blue.
