In Chinese the term kung fu translates as hard work. A more appropriate translation would be "hard work over time to achieve perfection". So with that being said what have you guys done that is kung fu? With me I am good at intellectual things my physical side needs work. Case in point at the end of wushu "Kung Fu" class we are "tested" over the meaning of Chinese terms or other things that have to do with the martial art if we get the answer wrong we do push ups. Very rarely can the teacher ask me a question that i don't know the answer to.
