Not in school, but I've seen documentaries and read books---hundreds of thousands of Chinese civilians raped, tortured, and killed by Japanese occupation forces who often liked to take photos of what they were doing and send them home to Japan. Some chilling and sick stuff. The Nazi representative in the city was one of many people who tried to save the civilians, things were so horrible.
I just listened to a bit about it on CBC radio....sad the way people treat one another..
Wow. I just read a book about it.
It got so bad even the NAZI government of Germany tried to intervene !
