On his travels, Chueh Yuan witnessed a bandit attacking an aged person. He saw how the attacker landed an apparently very strong kick seemingly, to the body of the traveler with very little or no effect. The old traveler only used minimal effort against the bandit's leg sending the attacker crumbling to the ground. This maneuver impressed Chueh Yuan enormously. Considering that Buddhist Shaolin needed a style that was more in line with Buddhist principles (not to do violence to others), this seemed like a good start. He introduced himself to the senior and inquired if he would be able to teach this art to him. Much to his surprise the old man did not know much of what he did and referred them to the local master Pai Yu-feng.

Pai Yu-feng was a friendly 50 year old and Chueh Yuan convinced him to accompany him back to the Shaolin temple. Over the next few years they, using the 18 Hands of Lohan, the 72 Fist Styles together with Pai Yu-feng's pressure point grappling/wrestling techniques' and redeveloped the Shaolin 72 Fist Kung Fu into the 170 exercises, a mixture Striking and Controlling, Evading and Countering. This was possibly the first official introduction of Vital Points to martial arts (it is now common for involved martial artiste to study the human body, meridians, joints, major organs and Dragon Points). This form of Kung Fu would endure for over 400 years before any significant changes were made
