Why did the old China have a sea, so the new China Navy could defend the maritime border of the motherland? Can you give an example?

1949 when the navy was first established, there were only a few wrecked ships left over from the Japanese puppet regime and a few small boats from the Kuomintang uprising. Navy commander Xiao Guangjin will go to Ahava to inspect Liu Gongdao. He didn't have a boat, so he had to borrow it from a small fisherman. The fisherman said, "You borrowed my boat as a naval officer?" After Xiao boarded the dock, he said with a heavy tone to the entourage around him: "Write it down. On March 1950, the naval commander visited by fishing boat." North Sea Fleet Resident: Qingdao Port of Call: Qingdao, Jiaonan, Lushun, Huludao, Weihai and Chengshan North Sea Fleet currently has three military naval bases: Lushun Base Qingdao Base Huludao Base Donghai Fleet Resident: Shanghai Port of Call: Shanghai, Wusong, Zhoushan, Dinghai, Hangzhou East China Sea Fleet currently has three military naval bases: Shanghai Base Zhoushan Base Fujian Base South China Sea Fleet Resident: Zhanjiang Port of Call: At present, the South China Sea Fleet has three military naval bases: Zhanjiang Base, Guangzhou Port Base and Yulin Base. The naval base of the Chinese People's Liberation Army troops stationed in the Hong Kong Special Administrative Region is stationed by the South China Sea Fleet and is also commanded by the South China Sea Fleet during operations. Outstanding achievements have been made in naval construction: guided missile destroyers and nuclear submarines, and the navy's multi-arms are driven to sea by warships, aircrew, submarines, military boats and land teams. Why did the old China "have no defense against the sea" and the new China Navy defend the maritime border of the motherland? In old China, the national strength was weak, the coastal defense was slack and it was unable to resist foreign attacks. New China is backed by powerful national strength and powerful modern naval defense force. The people's air force was established on the basis of the army, and it faced this war as soon as it was born. Can you name a few heroes in this war and their deeds? Wang Hai shot down four enemy planes and wounded five. Liu shot down six enemy planes and wounded two. Zhang shot down four enemy planes, shot down five enemy planes and wounded two. Why can his behavior be praised by the Chinese and Korean people? What inspiration did you get from it? 1 was born when the China Air Force was just born and the enemy was extremely powerful. Because he protected the interests of the people of China and Korea, he was not afraid of strong enemies, dared to fight and fight, and bravely killed the enemy, and achieved brilliant results. 3 inspiration is to dare to face up to challenges and bravely accept tests; We should work hard to protect people's interests or improve people's living standards. Compare the development of the People's Air Force and the Navy, and tell the similarities between the two armies? Is getting stronger; The content of modern science and technology is higher and higher; China has developed more and more weapons independently. How did China's military aircraft develop? How did it buy-imitate-develop 歼 5 歼 6 歼: China imitated the Soviet model and laid the foundation for China to develop its own fighter. 歼歼 7 and its portable weapon 歼 -7: It is the first fighter independently developed by China, and its model is modeled after the MIG -2 1 fighter of the Soviet Union, from which 歼歼 7-air has many high-tech achievements developed by China. The thrilling action is always the most beautiful flying leopard: it is an air destroyer and bomber developed by Hercules, a self-propelled fighter in China. It can be used as a fighter or a bomber flying leopard, which is a new field of China Air Force. Because its bomb load is much larger than that of ordinary fighters, it is also called "Hercules". Bomber: H -5 fighter: a series of fighter transport planes developed by Qiang in the 1950s and 1970s: Yun -5 tanker: Changhong. I would like to add that the active force of the Chinese Army is 65.438+0.7 million, including infantry, artillery, armored forces, engineering, communications, chemical defense and other specialized arms, as well as electronic countermeasures, surveying and mapping and aviation units.
