Bang and Chih

Bang and chih are a Chen Village training tools that provide strength training and flexibility for the upper body while practicing joint locks. These tools can be used to provide resistance at a variety of angles allowing the practitioner to build strength within reeling silk movement in martial application specific configurations.

Bang (pronounced bong) is often translated as "ruler." A better translation seems to be "dowel."


Chih is often translated as "angled ruler." A better translation is "stick."



• Learn mechanics of several joint locks, primarily wrist locks
• Learn strength training and flexibility training for the arms
• Perform soft fit-ins with a partner to get a real feel for the lock
• Perform fast/hard locks on the bang/chih


Simulate what you want to practice
Chih can be sized for a wrist or elbow. Angle is usually greater than 90º.
Bang can be forearm length or full arm length. The full arm length dowels are often used to practice throwing applications. The forearm length dowels are typically 16” L 1.75” D.

Type of wood
• One practitioner indicates that it is traditional to use a “warm” wood, not a “cold” wood. A wood used in China is Chinese Pepperwood. Rock maple sanded to 80 grit seems to have the right grip and maximal weight for the bang. The grain of oak does not give the same grip as rock maple.
• Oak works well for the chih, where the hands don’t need to slide on the implement. Note that I have a plywood chih from a traditional Chinese teacher.


• There are some traditional stepping patterns (ba gua, seven stars), but don’t use those patterns as limitations
• Use the concept of the Japanese term “tai sabaki” in simulating the lock that you are performing. Tai Sabaki: footwork to avoid an aggressive action while positioning yourself to counter-attack.
