Japan invaded northeast China in September 1931 and conducted the full-scale invasion on July 7, 1937, when a bridge that acted as a crucial access point to Beijing was attacked by the Japanese. Since then Chinese people began 8-year War of Resistance against Japanese Aggression. Famous historian Zhang Dongpan got old photos about China, the main battlefield in Asia during WWII, which reminds us of those war-ridden years. (Photo/Chinadaily.com)
