Chinese women in the Second Sino-Japanese War
Most women in China were profoundly impacted by the Second Sino-Japanese War (also referred to in China as the War of Resistance), in which the Empire of Japan fought the Republic of China starting in 1937, primarily due to the Marco Polo Bridge Incident on July 7, 1937. On September 2, 1945, Japan formally surrendered.
