Circles
Taiji moves in circles. All movements are circular: to the side, the front, horizontal, vertical. Hand movements are circles: ni chan (twining outward) and shun chan (twining inward). The whole entire body is held as a circle as if it were a globe, a ball, or a balloon. Twining enforces small circles of knees and elbows, of ankles and wrists. Shoulders match hips in circles.
