The style of Chen Taiji's biography is characterized by generous posture, light and steady footwork, natural posture, inner strength dominating the whole body, winding strength as the core and waist as the axis. When you move, your whole body does not move, and all the bones are still. Action is like running water, continuous, and it is loose when it is excited. Requirements in practice: empty collar, tall and straight body, loose shoulders and heavy elbows, chest and waist collapse, depressed mood, natural breathing, loose hips and knees, full crotch, clear distinction between reality and reality, up and down, rigid and flexible, alternating speed; The appearance is curved, the inner strength is spiral, the hand pulls the body, the waist is the axis, and it is wound round and round, gradually producing an inner strength that seems soft but not soft, seems rigid but not rigid, and is extremely heavy and extremely soft, such as cotton wrapped with iron, soft outside and rigid inside. The whole set of boxing has no plane, no straight line, no discontinuity, no convexity and concavity, no stretching, no promotion intention, and it is completely round and qualified. Turn wrist to shoulder, waist to cross, ankle to knee, chest and waist to fold, forming a set of continuous spatial curve movements from head to toe.
