The Pingdingshan massacre was a conflict between Japanese troops against anti-Japanese Chinese militia during the Pacification of Manchukuo on September 16, 1932.
On September 15, Anti-Japanese Red Spear militia, not from the area, but passing through Pingdingshan village, fired on Japanese soldiers and later attacked the Japanese garrison in the nearby industrial city of Fushun. The next day in retaliation Japanese soldiers and police in tracking the rebels as they fled back through the villages, assumed all who were in the vicinity either to be members of the militia or their confederates and punished them, by burning homes and summarily executing, bayoneting and machine-gunning village residents and killing some three thousand men, women, and children, leaving few survivors. The bodies were burned and the village of more than eight hundred houses was burned down.
In 1972, remains of 800 dead compatriots were found in a mass grave 80 by 5 metres in size. A memorial hall was constructed to house these remains. It is situated in Xinbin Manchu Autonomous County in the prefecture of Fushun, China.
