(II) Coordination: Tai Chi Chuan is an exercise for the whole human body. It calls for the movement of all parts at the same time, and good coordination among them. In executing the “cloud hand,” for example, when the waist is turned, it drives the arms out to draw circles in the air with the palms turning inside and outside together continuously with the movement of the buttocks, and the legs supporting the entire body to move and turn to the 1eft or to the right, while the head also turns naturally with the torso. At the same time, the eyes look at the upper hand. In this way, the whole body moves in coordination, with close cooperation between all the body's elements.
