On May 15, 1942, the Japanese army launched the Zhejiang-Jiangxi campaign in order to get rid of the U.S. army’s threat of air strikes against the Japanese homeland. On May 21 of the same year, Japanese troops invaded Yiwu. On September 3, 1942, a Japanese army’s plane flew in low altitude over Chongshan Village. The plane didn’t throw bombs, but emitted a long trail of smoke-like substance from the tail of the plane. After over 10 days, the belly-up dead rats could be seen everywhere in the village. On October 12 of the same year, villager Wang Huanzhang has plague symptoms of Yersinia pestis and died in 3 days. It was just a beginning. The plague rapidly spread in Chongshan Village and surrounding areas. On December 8 of the same year, within two months, 403 persons died in the plague and 23 families died in Chongshan Village. The death toll accounted for one third of the whole population.

During that period, the Japanese 731 troop and Nanjing Rong Zi 1644 troop invaded the village for two times, and dug up the new tombs of the victims to take away the limbs and livers. Even worse, they conducted vivisction. They named the Yersinia pestis bacteria extracted from villagers of Chongshan Village as “Songshanzhu” and used the bacteria as the breeding mother. In order to destroy the evidence of the germ warfare, on November 18, 1942, the Japanese army set fire to the village, and burned down 176 households or 421 rooms, which led to the displacement of over 700 villagers.
