Can anyone tell me the name of this kung fu movie?
Details: one of the mean character was a silver head(long white hair) expert who weak spot was hard to find,he hardly smiled ,had mastered several martial art techniques.He practiced with fire9hands punching hot charcoal),water,etc..At the end his opponent found his weak spot which was at the bottom of his feet(I think had to make him laugh). I was a small child when it came out I believe in the 70's or early 80's,no guns or cars in it old style country Chinese movie.
TIA
