Zhang Shuangbing looks at the screen of his laptop on March 2, 2016. For more than 10 years Zhang Shuangbing, a retired Chinese village teacher, painstakingly recorded the heart-wrenching experiences of 129 Chinese women who were forced into sexual slavery by Japanese invaders during World War II. Women forced into sexual slavery by the Imperial Japanese Army before and during World War II were called "comfort women." Research shows some 400,000 women in Asia were forced to be "comfort women" for the Japanese army during World War II, nearly half of whom were Chinese. However, the Japanese government has refused to acknowledge legal responsibility for the "comfort women" issue so far. Reporters from Xinhua spent many years to look for the victims and recorded their current lives. (Xinhua/Zhan Yan)
