What would you do if your arm is held by an opponent?

There is a kungfu saying that "the hands open the way, it is the legs that decide victory". The saying indicates that kicking attacks are very important in combat. The legs are also very important in defence. Here, Grandmaster Wong explains and demonstrates how by using good footwork you can neutralize all the four categories of attack, namely striking, kicking, felling and chin-na. He also shows the difference between having good stances and bad stances in the same combat situations.
