i read an article on this the other day. Here's the abbreviated version: pak mei was a shaolin monk in the 1600's when the manchurians (or the 'ching') took power in china. these were rebellious times and the shaolin temple assisted in a rebellion against the ching. However, a monk was dismissed from the temple for breaking a sacred lamp. He betrayed the temple and led the manchurian forces to its destruction. 18 monks survived. Of these, 13 were hunted down and killed. The remaining 5 fled to a taoist temple to the north, where they developed a new system of kung fu. The monks challenged each other and it was found that, of all, pak mei was the most skilled. he was sent, with a small group of students, to spy on the ching royal palace. The group was captured. In order to save his students from torture and death, pak mei was forced to join the manchurians. He taught them his new style and led the army to the secret location of his comrades. All were killed and the temple once again was destroyed. pak mei was set free and spent his days teaching kung fu and taoism. word spread of his betrayal and his form became known as the forbidden style. he reputedly lived to over 100 years old.
