It’s estimated that at least 200,000 Chinese women were forced into sex slavery by Japanese troops during World War II. More than 70 years after the end of the war, director Guo Ke located some of the survivors and filmed them over a period of three years. The lives of these women can be seen in the new documentary, “Twenty Two”, which opened in Chinese theaters on Monday to coincide with the International Memorial Day for Comfort Women.
