oh wait, scratch that - i got it wrong.
fist of legend is a remake of the bruce lee film "fist of fury". it's honestly a better version IMO, although i love Lee as much as anyone.
"the legend of fong sai yuk" was renamed simply "the legend" recently when it came back into print. it takes place in the fuedal era and has a very elaborate plot for a kung fu movie. there are two sequels to it that are great too. i highly recommend it for jet li fans!!
oh i watched some of fist of fury but i couldn't cope with it (although i did see the scene where the karateka attack the kung fu school). Li's version doesn't waste as much time it has a better plot and is culturally better; the original is very racist as the chinese hate(d) the japanese and lee really played that up.
Enter the Dragon just kicks some serious a$$ though. can't falter him on that.
Go seek the advise of a qualified instructor.
