"Archive footage filmed in 1937 features Chinese troops fighting with Japanese forces during the 'War of Resistance Against Japanese Aggression'. Footage shows soldiers, both male and female, training and fighting on the battlefield and in a town. Military leader Chiang Kai-shek is seen addressing the troops. The video also shows civilians involved in digging trenches and other defence constructions. People can also be seen hiding in mountains during Japanese air raids. The Second Sino-Japanese War between China and the Japanese Empire had its roots in 1931 with the Japanese invasion of Manchuria, becoming the largest Asian war in the 20th century. It was reported to have resulted in the deaths of around 20 million people, mainly Chinese civilians. Following WW2, Japan formally surrendered on September 2, 1945, after the Soviet declaration of war, as well as the US atomic bombing of Hiroshima and Nagasaki. China holds its landmark 80th anniversary Victory Parade in Beijing on September 3, attended by many world leaders and dignitaries."
