Flying Crane
Sr. Grandmaster
I have always understood that Tibetan and Fujian crane developed independently. They do not share a history, one did not derive from the other, they did not diverge from a common ancestral method. If you look at their forms, they are quite different. Not just the choreography, but the foundation and fundamental methodology of their techniques. To even the casual observer it is evident that they are completely different approach.Makes senses, there's a long cultural connection between the two.
Keep in mind both went through centuries and centuries of military dynasty pressure to be effective or die on the battlefield.
Different people in different geographic regions found inspiration in the same animal and the fact that they both call their system White Crane is coincidental.
