At an international symposium on Japan's Unit 731 in Harbin in 1995, two Japanese scholars reported an outbreak of pestis in Chongshan Village in Yiwu City of Zhejiang Province. They concluded that the outbreak was the result of Unit 731's germ warfare. Wang Xuan, who attended the meeting, was shocked to know that the village is her father's hometown. Wang's uncle was also killed by the epidemic when he was 13 years old.

 

Wang decided to quit her job and help victims' have their voices heard. Wang and Japanese lawyers and scholars began to investigate and collect evidence of Japan's germ warfare in China during World War Two. In 1997, a plaintiffs' group was founded in China by 180 members, many of whom are victims of the war. Wang was selected as the head of the group.

 

Since then, Wang has led the group to sue the Japanese government all the way from a Tokyo district court to Japan's Supreme Court. During this long process, many victims have passed away without an apology from Tokyo. Wang thanked many Japanese friends for their efforts to assist these victims and unveil the war crimes committed by their country. Despite the Japanese courts refusing to rule in their favor, Wang vows to continue her fight.
