Kunf fu movie with a iron shirt kung fu style, pacifist sort of guy

[7crossroads]

The movie, as far as i remember, tells the story of a young martial artist, who learned iron shirt kung fu  and basically been kicked and punched by the bad guys the major part of the movie (while remembering his masters saings "tolerate"). His pacifist master was killed by those bad guys.  Eventually at the end, he fights back and destroy the bad guys.
Someone remember this movie? Thank you!
