The Chum Kiu is about bridging the gap. The hands and arms are hereby referred to as bridges. You are going to search for the hands with the intention that you make contact with the hands and arms in order to createt a bridge. Bear in mind the principles. If the hands of your opponent are behind his back, you are not going to create contact but hit right through the center to the center of the opponent.
Chum Kiu, in contrast to the Siu Lim Tao, combines most movements: usually two arms are engaged at the same time. Often this is an attack and defense at the same time. Also legs are at work in the Chum Kiu. Whereas in the Siu Lim Tao you were fixed to one position, the Chum Kiu combines walking, turning and kicking.
