1On August 3rd, 937, 700,000 Japanese troops (including most elite troops) launched a three-month war against China in Shanghai. Although China's army paid a huge price, the Japanese army with superior forces finally defeated China's army and occupied all areas except the concession by force.

Therefore, in 1938, the Japanese occupied Shanghai (except the concession), and the French concession in Shanghai and the half of the Shanghai concession south of Suzhou River began an island period of more than four years.

Politics: At this time, various forces at home and abroad were mixed and wrestled with each other, forming a unique period in history.

Culture and Art:1In the 1930s, a large number of cultural celebrities gathered in Shanghai. In the 1930 s, American Hollywood movies were very popular in Shanghai. During this period, the Daguangming Cinema on Jing 'an Temple Road in the public concession and the Cathay Theatre on Joffrey Avenue in the French concession were established one after another, with luxurious facilities, specializing in showing Hollywood movies. Second-and third-rate cinemas also show domestic films. At that time, China's film industry was basically concentrated in Shanghai.
