Ma Xiuying, born in 1922, survived by escaping to a refugee zone with her mother during the invasion of Japanese troops in 1937. Japanese troops occupied eastern China's Nanjing on Dec. 13, 1937, and began a six-week massacre. Chinese records show more than 300,000 people -- not only disarmed soldiers but also civilians -- were brutally murdered and thousands of women raped. In the past 79 years, the number of survivors decreases. After Zhang Fuzhi, 89, passed away on Nov. 26, 2016, the number of the registered survivors reduced to 108. With hurt that are unable to heal and tragic memory of suffering, survivors are the witnesses of the massacre. (Xinhua/Han Yuqing)
