How to prevent Tai Ji Chuan's hip movements during the catwalk?

1. First of all, the "rotating sinking" on one side of the real leg will stabilize the body center of gravity on the real leg 100%, and the virtual leg will not bear any weight and be light.

2. Secondly, "leading the knees with hips" means that the legs of the limbs are driven by the body and realized by the "rotation and sinking" of the real legs. That is, when one side of the real leg "rotates and sinks", it prevents high and low hips.

3. Finally, after "rotating and sinking" on one side of the real leg, it is natural to avoid doing it deliberately, which can prevent high and low hips.
