I just came across a documentary called Nanking (2007) on Netflix, about Nanking Massacre during Japanese occupation in WWII. That was the city I was born and grown up in. In the end, the movie showed some street views of modern Nanking and brought up my memory.
When I was at school there, seldom was I told about how those Westerners protecting Chinese. I didn't know they saved 250, 000 lives there. (In contrasted, Japs killed 300,000 people there.)
If the Jewish people never forget Schindler, Chinese should never forget those who saved us during the Japanese occupation.
