Abstract: In the 1950s, China's navy was weak in equipment and professionals. In order to build a new Chinese naval force, China sent naval cadets successively to study in the Soviet union under the background of Sino-soviet friendship. Confronted with the hard life and the intense study, China's naval cadets successfully finished study after continuous efforts. After returning to China, they became the backbone of the People's Liberation Army Navy. With the advanced naval technology and the advanced naval strategy and tactics they learned in the Soviet Union, they served the Chinese navy construction and the talent cultivation, and made outstanding contributions to the development of the People's Liberation Army Navy.
