When a small regiment of troops came to Lai Tung and started to cause trouble, Yuen Mau had had enough. Having trained the monks in the art of Poon Kuen, the monks defeated the soldiers and brought peace back to the village (It is likely that the troops were either deserters or a group of bandits, as the army would have surely not taken an attack like this lightly; the other scenario is that the monks killed the troops and, being a small force, the army never went looking for them. As with all legends, there is always an element of truth to them). Yuen Mau then called the art Lai Tung Pai or “family of Lai Tung Village” after the town he helped defend.
