The Body Moves from the Center
The body moves from and around the vertical core or ‘ding’. The ‘ding’ is a vertical axis that hangs from bai hui, a point at the top of the head to the hui yin, a point at the base of the perineum. At the end of each form the body settles back into place with ding being upright and central. In the winding the full body is connected with the winding center that moves through the waist.
The left (or right) arm does not pass the left (or right) side, each arm does not pass the center line, the core, the center of the chest. Arms move because the center core, ‘ding’, moves in a winding manner. When the body turns the arms move, but not too far. The arms stay aligned with the center of the body in the front of the chest. Moving from left side to right occurs only because of waist turning.
When the body moves from the center the elbows are connected and move together, likewise hand with hand and hip with hip. When moving stay smooth. Each form is executed as one smooth move without stops and with an even flow with twisting and turning.
