This topic examines the national defense and diplomatic achievements of New China. The historical event reproduced in the above three photos is the success of the atomic bomb explosion; Nixon's visit to China; The return of Hong Kong. In 1950s and 1970s, China also made achievements in national defense construction, including the successful explosion of the first hydrogen bomb and the successful development of missile nuclear weapons.
