Yuan,
Ill ask my Sifu what sect it is and get back to you. Since the art was made from Lao Tzu's senior disciples i guess you can trace it sect to Lao Tzu?
Where did you get your info from?
it's exactly what you describe. it's Primordial Chaos sect. parent sect of Black Turtle sect. tell me about your style?
Im still new to the art of Wun Yuen, mostly its using No Intent and the body is controlled by the Buttock muscles. So for your arm to move the buttock will do it etc so alot of training in turning, rotating, squeezing, releasing the Glute muscles.
The healing hands and some of the body breathing meds use some intent but just to activate the chi.
hope this helps for now,
regards
Garry
