Also during the thirteenth century AD, Chiao Yuan, another practitioner of Bodhidharma's fighting system, systemized Kempo techniques, basing them on the movements of five creatures. Although he made a significant contribution to Kempo, since he only taught his system to Buddhist priests, his system did not become widely known. Yuan's system was categorized as follows:
- Dragon: Assume a natural position and coordinate body and spirit. At the proper moment, attack with the swift power of a dragon swooping from the sky.Tiger: Use the power of the arms and hips in a body movement similar to an attacking tiger leaping from the forest.
- Leopard: Leap nimbly, similar to a leopard, and move with its agility.
- Snake: Move with the fluidity of a snake and strike with your fists similar to a snake strike.
- Crane: Assume the calm, stately poise of the crane and attack with grace and smoothness.
