A lot of movements in Taijiquan are from the waist and not from the hands

"Chin-na", an art of disabling opponents by using special ways of gripping, is an important aspect of Taijiquan, but not many Taijiquan practitioners may realize it. "Double Dragons Play with Pearl" and "Pushing Boat According to the Current of Flow" are two examples of chin-na techniques in Taijiquan. In "Double Dragon" the main movement comes from the waist and not from the hands. In "Pushing Boat" the palm of one hand should be placed on the wrist of the other hand, and not on the other palm.
