7. I absolutely believe that looking at the physical aspects of the various arts for common structures and concepts is just as important as looking at any lineage stories. I can see Wing Chun, Tang Yik Wing Chun, and White Crane coming from a common source or sources and then evolving in their own directions. To me, Weng Chun is even more like "ancestral" White Crane than is Wing Chun! So I could see this proto-typical art at some point combining with a "snake" art to produce what we think of today as Wing Chun. From what I've seen and experienced, Wing Chun definitely has a more "snakey" aspect than Weng Chun, while both have a "craney" aspect. But if we are going to take seriously this analysis of form and concept, then we have to account for the Hakka arts and why some of them are so similar to Wing Chun. As I stated before, to me there is a lot more physical and conceptual commonalities between Wing Chun and Southern Mantis than there are between Wing Chun and Hung Kuen. Yet everyone seems to just accept Hung Kuen as a Wing Chun predecessor. Disclaimer here......Sifu Michael Tang does not agree with the idea that Weng Chun came from a "White Crane" ancestor. I told him my theory as just stated above and he disagreed with me. He holds to the story of Chi Sim taught a distillation of Shaolin systems and that this was the root of Weng Chun.
KPM, there is no need for any White Crane or even Hakka Boxing to explain Wing Chun
- go to the old villages in countryside in Guandong Province, take a look at the various Lo, Siu and Fa Hong Kuen styles they practice and ask them to explain some concepts to you.
It is true that styles like Naam Pai Tong Long have a lot of commonalities with Wing Chun, but one thing to consider... Traditionally, Hakka people would not teach their art to non-Hakka, which means that these styles would not have been widely available such as the various forms of Hong Kuen were.
