Any documentaries on China/Taiwan involvement in WWII?

I know most documentaries in English on WWII is often centered on the US, on how they beat the Germans and Japanese and all that, but I know China was a major player in WWII as well as they were eaten up by the Japanese. So I wonder, are there any good documentaries about China’s involvement in WWII, in bot Chinese or English?

I remember seeing one on the rape of nanking…

Just for fun…
Look for the 3 Stooges
"Slowly I Turned/Niagara Falls skit filmed at a Navy Base. Look carefully at the flags flying in the background.
You will see one that can’t see today.

I learned a bit from this.
