The Chinese film 731 Biochemical Revelations, which revisits the horrific World War II-era human experiments conducted by Japan’s notorious germ warfare unit 731, is set to premiere on September 18, 2025. On that special day, one of the darkest moments in the history of human civilization will be unveiled when screens light up in film theaters.

Every year on this day, the wail of air-raid sirens resounds through 14 cities in Liaoning Province, standing as a recollection of the atrocities committed by Japanese invaders, and a poignant reminder of the national calamity. As part of the events commemorating the 80th anniversary of the victory in the Chinese People’s War of Resistance Against Japanese Aggression (1931-45) and the World Anti-Fascist War, the bell of the 9.18 Historical Museum in Shenyang will ring again on September 18, 2025. Meanwhile, the film 731 Biochemical Revelations will resonate with the echoes of the alarm bells, touching the heart of everyone.
