The Chen style taiji quan falls into two categories - the old and new frames. The old frame was created by Chen Wangting himself. It had five routines which were also known as the 13-move boxing. Chen Wangting also developed a long-style boxing routine of 108 moves and a cannon boxing routine. It was then handed down to Chen Changxing and Chen Youben, boxers in the Chenjia Valley who were all proficient at the old frame. The present-day Chen style boxing boasts of the old routine, the cannon routine and the new routine. The Chen style taiji boxing is the oldest form, all the other styles of taiji quan having derived from it either directly or indirectly.

The Routine II of the Chen-style New Frame Taijiqun is called Cannon Hammer. The structure of routine is complicated. Its movements are quick, compact, swift and violent. It takes the Pulling Downward, Bend Backward, Elbow Stoke and Shoulder Stroke as its main forces, and Ward off, Stroke, Push and Press as its auxiliary forces. And stress on the exercise of the springiness force.
