Grandmaster Wong uses his leg to deflect Sifu Mark's knee attack

Instead of deflecting an opponent's kick with your hand, you can deflect the kick with your leg. This is the Wing Choon principle of "kheok lei kheok ha siew", or "when leg comes, counter with leg". Grandmaster Wong also shows how you may move to an opponent's back as he attacks, or how to make the first move to attack him.
