Introduction to the tragic atrocities committed by the Japanese army: On the night of the Mid-Autumn Festival on September 15, 1932, about 1,200 people from the Liaoning People’s Anti-Japanese Self-Defense Force, led by Liang Jufu, passed through Pingding Mountain to attack Fushun and burned the Japanese warehouses, factories, and police stations in Pingding Mountain. , offices, etc., and then marched to Donggang, Laohutai, Yangbaibao, Dongxiang and Guchengzi. On the way, they attacked the Japanese charcoal mining station in Yangbaibao and executed Watanabe Kanichi, the director of the charcoal mining station. Self-defense regiment leader Hirashima Zensaku and seven or eight Japanese set fire to the charcoal mining station. The Japanese army in Fushun had nothing to do with the anti-Japanese armed forces and angered the innocent civilians. Since the anti-Japanese armed forces passed through Pingding Mountain in the suburbs of Fushun and no one reported the residents here, the Japanese Fushun garrison determined that the residents here were "complicit in bandits". So it was decided to retaliate with massacre.
