How can I find out what film this is?

I owned a martial arts film 10 years ago. It was about two guys (one fought with a fan the other a sword) and a gang of thieves. It was set in the past like 100 years ago or more. I can't remember what it was called and it's really bugging me. The guy with the fan slept with prostitutes and the guy with the sword was more straight laced. Please someone help me!
