add a twist

From the basics of baguaquan page of http://www.baguaquan.idv.tw/

“A solid stance should keep solid, that means when we move our whole body, the stance ( ankle, knee, kwa ) shouldn't move or shake, when we walk on the circle, we twist our torso to the center, but the pelvis should still face to circle, if the stance follow the torso turn to same direction, there is no twist at all, a twist means one end of the twist keep steady while the other end twisting.”

From just an attempt at applying these principles, I feel that right away I notice differences: a more solid stance, and less strain on the knee, less hunching of the shoulders.
