Nanjing was the capital of china during WW2. The Japanese invaded, killed everyone, and raped almost every female alive from the age of 3 to 100+. Male chinese were forced to rape dead female chinese or risk getting killed. Once they followed the order, they were subsequently killed anyway.
Families were forced to commit incest of risk getting killed. Sons were made to rape mothers, Fathers forced to rape their daughters, brothers forced to rape their sisters. Thereafter, the males are killed and the females are gangraped by the Japanese.
Pretty female chinese are taken away and used like "public toilets". They are housed in "comfort stations" and chained or tied down. Japanese soldiers would line up outside and take turns to rape them. Once a female becomes too sick/disgusting/worn-out to arouse the japanese, they would be killed.
