The match was fought

on the stage of the Red Junk, Wong with a twelve foot Dragon Pole against Leung's pair of eighteen inch butterfly swords. Wong figured he had the advantage, and invited Leung to attack first. Wong found it very difficult to defend against the swift, tight techniques of the swords, and was forced to the edge of the stage. In desperation, Wong used the most deadly techniques of the pole, blocking Leung's double slash at his head with an upward bon kwun, then jabbing low at Leung's leg. Despite the almost simultaneous block and attack, Wong's strike missed, and he felt the cold steel of Leung's butterfly blade against his wrist. He had no choice but to drop his pole and concede defeat, begging Leung to teach him the superior techniques of Wing Chun.
Leung knew from the fight he had chosen well. Wong mastered the art of Wing Chun, and integrated its principles into the technique of the six-and-a-half strike Dragon Pole, thus making that weapon part of the Wing Chun system.
Next in the lineage was Leung Lan Kwai, a herbalist by profession, who introduced the Iron Palm training into the system. Leung Lan Kwai passed his knowledge to Leung Lee Tai, who then passed it on to Leung Jan, a famous herbal doctor in Fatshan. Leung Jan was famous for his Iron Palm technique.
