It's weird when kids that you taught Kung Fu become men.. and also are doing stuff that you want to do. When I met (I guess he goes by D.J. now but when I knew him he was Zi Cong) he actually didn't speak English. But now he is vlogging up a storm.. something which I am just starting to wet my feet at, but am obviously not as fluent in.
A Sifu must never forget that everyone you teach, can also potentially teach you something, or perhaps teach either now or in the future.
