Kung Fu movie name...?

Please help me find this movie. It's bothering me so badly. It's a
Kung Fu movie, and I don't remember much, other than there's this
scene where a girl (a wife or girlfriend of the main character) fights
the main character in a match of some tournament or something and
beats him. I think the main character is trying to get some kind of
item, I don't remember what he does with it. But the wife (or
girlfriend or whatever) was angry or something because he went off to
fight, so she went and fought him in one of the matches. Please help.
I know it's not a lot I remember but I want to know so badly.
