1920-1950 Asian history dramas

This one is soooooo boring besides the cool action scenes. Not recommended. Basically the Chinese communist army against the Japanese army.

Interesting story about Japanese occupation of a Chinese city where a church is the main focus of the story. The English is not very good but its still ok.

Japanese occupation of Korea.

Japanese occupation of Korea with a fictional superhero for Korea. 

Japanese scientists in WW2.

Chinese soldiers in WW2 against Japanese forces.

Chinese blood brothers join different war-groups in WW2 and meet again as enemies.
