This year also marks the 80th anniversary of the victory in China's war of resistance against Japanese aggression and the World Anti-Fascist War. Unit 731, a top-secret biological and chemical warfare research base in Pingfang District of Harbin, the capital of northeast China's Heilongjiang Province, served as the nerve center for Japanese biological warfare in China and Southeast Asia during WWII. Historical records suggest that between 1940 and 1945, Unit 731 used at least 3,000 people in its human experiments, and more than 300,000 people in China were killed by Japan's biological weapons. "We hope this film will direct more attention to the understanding and study of Unit 731 and its history." "Through the power of cinema, we hope to bring the truth about Unit 731 before people around the world."
