HARBIN, Sept. 18 (Xinhua) -- "The real history is far more brutal than what the film can depict," said Jin Chengmin, curator of the Exhibition Hall of Evidence of Crime Committed by Unit 731 of the Japanese Imperial Army.
Unit 731, a top-secret biological and chemical warfare research base, was established in the Pingfang District of Harbin, and served as the nerve center for Japanese biological warfare in China and Southeast Asia during World War II.
Historical records suggest that between 1940 and 1945, at least 3,000 people were used in human experiments by Unit 731, while more than 300,000 people in China were killed by Japan's biological weapons.
