I've often compared Kiu Fung's adoptive Han parents, the Kius, to the Kents - the American farmers who raised the Kryptonian Kal-El to become the hero Superman. It was his Kryptonian heritage that gave Kal-El his great superpowers, but it was the strong morality with which the Kents raised Kal-El (as Clark Kent) that made him SUPERMAN, protector of the weak and champion of justice.
Do you think Kiu Fung's case was similar? His martial arts talent was his own, but his heroic character...did that come from the way the Kius raised him?
