What is the sequence of the movements of the waist, hips, legs and feet when moving in and out of traditional Yang's Taijiquan?

According to traditional taijiquan theory, taijiquan practitioners need to abide by the principle of "Three Harmonies" - Hands and Feet, Elbows and Knees, Shoulders and Hips.

In the specific macro, it is reflected in the hips, shoulders, elbows, knees, hands and feet are moving together, a quiet and quiet. Simply put, the same in and out, the same static and movement. In the microcosm, there are more detailed sequences - the variations of which are inexhaustible and require constant practice and refinement to experience. But the specific requirements of the hands and feet, elbows and knees, shoulders and hips are unchanged.

And in different schools and contexts, these requirements are modified accordingly. For example, some schools of pursuit of beautiful and generous action, often the first foot, and then move the waist and hips, and finally hands; and in the stage performance, in order to make the action more hierarchical, but also often require the table to be the first to move the foot, and then move the waist and hips, and finally hands.
