File photo taken on March 31, 1939 by a Japanese army surgeon shows Japanese soldiers posing for a photo after they beheaded a Chinese in east China's Jiangxi Province. During WWII, around 400 million Chinese people were involved in the war of resisting against Japan's aggression. A large number of them suffered starvation, illness, injury and torture from Japanese invaders who had committed crimes of destruction, pillage, rape and slaughter since they invaded northeast China in September 1931. As of a full-scale invasion on July 7, 1937, random killings and indiscriminated bombings not only made mass casualties of innocent civilians but also rendered tens of thousands people homeless. Some 35 million Chinese soldiers and civilians were killed or injured during the war which lasted until 1945. (Xinhua)
