How to realize the change of reality and reality in Tai Ji Chuan's boxing process

Tai Ji Chuan's center of gravity transformation process is the change of reality and reality.

Under the guidance of the theory of Yin-Yang transformation, Tai Ji Chuan always has Yin-Yang transformation in every situation and every action, that is, the transformation of reality and excess. For example, the cloud hand, the left foot is empty and the right foot is solid, and the left foot steps sideways; When the left foot is solid and the right foot is weak, the right foot moves toward the left foot. The center of gravity of the body also changes with the actual situation of gait, and there will be no feeling of delay and heaviness. It is a change of reality.
