Attributed to Zhang San Feng, a Taoist Immortal. In motion, the whole body should be light and agile,with all parts linked as if threaded together. The chi should be activated,The mind should be internally gathered. The postures should be rounded and without defect,without deviations from the proper alignment in motion, your form should be continuous, without stops and starts. The jin should be rooted in the feet, generated from the legs, controlled by the waist, and expressed through the fingers. The feet, legs, and waist should act together as an integrated whole, so that while advancing or withdrawing one can take the opportunity for favorable timing and good position. If correct timing and position are not achieved, the body will become disordered and will not move as an integrated whole. The correction for this defect must be sought in the legs and waist. The principle of adjusting the legs and waist applies for moving in all directions - upward or downward, advancing or withdrawing, left or right. All movements are motivated by Yi, not external form. If there is up, there is down, when advancing, have regard for withdrawing, when striking left, pay attention to the right. If the yi wants to move upward, it must simultaneously have intent downward. Alternating the force of pulling and pushing severs an opponent’s root so that he can be defeated quickly and certainly. Full and empty should be clearly differentiated. At any place where there is emptiness, there must be fullness. Every place has both emptiness and fullness. The whole body should be threaded together through every joint without the slightest break. Long Boxing is like a great river rolling on unceasingly.
