Wing Chun....
Was a women who didnt want to get married, Ng Mui was a nun.
As for having to be small to learn it, absolutely not, it is just an art designed to be effective for small people. We have a guy in my WC class that is about 6'2" and around 250-260lbs, and he does just fine (rooting drills with this guy is like pushing on a brick wall! I am pretty sure he fell asleep last time him and I were doing our drills!)
I am not a small guy, about 6', 210 lbs and I really enjoy the art. It is about direct and structural straight line power not 'small' power.
I would think this extends to other arts in that they weren't necesarily built just for small people and even if they were, my sifu always says to take your art and make it yours.......
