One hundred years ago, a group of Chinese young people studied in Britain to study the navy. After returning to China, the younger brother and others served as captains of the Beiyang Fleet, making the Beiyang Fleet the most powerful fleet in Asia.　　Japan accelerated the construction of its navy, and the emperor took the lead in donating money to enhance the quality of warships. The Qing government was full of corruption, and those in power embezzled the navy's military funds to repair the Summer Palace in order to curry favor with the Empress Dowager.　　Finally, Japan launched a naval raid on China, provoking the Sino-Japanese War. The Beiyang Naval Division resisted bravely, and at the moment of life and death, Deng Shichang, the captain of the Zhiyuan, drove a seriously injured ship to attack the enemy ship, but unfortunately was shot and sank. The emperor's personal letter: On this day, the world is full of tears, and there is a strong navy!　　The Beiyang Fleet was trapped at the base of Liugong Island, and Liu Buyun and other generals would rather die than surrender, and committed suicide in anger. And the younger brother was dissuaded and surrendered in humiliation for the sake of revitalizing the navy in the future. The emperor's change was suppressed by the empress dowager, and the Eight-Nation Coalition plunged China into an even greater desperate situation, and the younger brother led the Beiyang naval division to watch the foreigner warships slaughter the Chinese and was ordered not to return fire.　　Ten years later, the younger brother agreed to the request of the officers and men on the Wuchang River, and the fleet turned its guns and revolted, ushering in a new era in China.
