Current chinese main title: 楊子江風雲

I believe the character 楊 is just a mistake by the editor who added the movie, because I don't think the producers didn't know how to write Yangtze River correctly (see Alias 揚子江風雲). All sources I can find say 揚 (posters, onscreen title, advertisements found by google). I'll change the mentioned Alias into the main title soon, of no one objects.

I absolutely agree.

Corrected the Chinese main title and deleted the obsolete alias.

If nobody objects within 1-2 weeks, I will merge these two companies and change the name into Chinese only (as I can't verify any of the two english names) and delete it from the 1969 movie, because I think it was added accidentally due to the the same title/alias (一寸山河一寸血):
