It was a guy who wears a straw hat in the 70's-80's kungfu movies called the lotus man what film was that?

in the film he had a alter ego kinda like superman and clark kent where he pretented to be weak and not know kungfu and the straw hat covered his face so you could not see it when he became the lotus man.He fought a guy at the end of the movie who pretented to be the lotus man and they wore white gi's with black belts and straw hats as a matter a fact they looked like raiden on the 1st mortal kombat games.So thats my question what was the name of this film?
