In 2007, a group of Liberal Democratic Party (LDP) lawmakers denounced the Nanjing Massacre as a fabrication, arguing that there was no evidence to prove the allegations of mass killings by Japanese soldiers. They accused Beijing of using the alleged incident as a "political advertisement". That same year, Xia Shuqin won a defamation of character suit against Japanese massacre denialists who argued that she had fabricated testimony relating to the death of seven of her eight family members during the Nanjing Massacre. Only eight at the time, Xia had herself been bayoneted, but survived, while her four-year-old sister escaped detection under the bed quilts.
