Cheng Man-ch’ing’s Taiji “Cloud Hands” stepping and other alternatives

In this video, Cheng man-ch’ing’s way of teaching “Cloud Hands” is shown and then compared with the timing of the sideways stepping based on his more-advanced concept of dong dang, which he wrote about separately in two books. Also examined are (a) the question of where the center of the circular motion of each hand is located and (b) the idea that the centers of the hands move basically one above the other rather than laterally apart.
