From 1931 to 1945, the Chinese people endured extreme hardship during their 14-year war of resistance against Japanese aggression, which contributed greatly to victory in the World Anti-Fascist War. This struggle is vividly presented in the documentary film "Mountains and Rivers Bearing Witness," which combines a vast amount of video material, including rare footage of the Chinese people rising up against Japanese aggression under the leadership of the Communist Party of China. The film is set to hit cinemas on Friday.
