So some of the recent posts and discussions have been about styles and how it can different. We see this in taji for example when I try and look online to find a starting point it seems one of the main branches comes from Wang Zongyue. Yet out of that we have today Chen, Yang, Wu, Sun and Hao. This I think happens in many styles, but I've been looking more into researching and reading books on taiji so that's what I mentioned I am thinking that every time a person learns a style and reteaches it changes a bit from the original. I also think that people will add something to it from time to time. Like Wong Fei-Hung and Hung Gar. He was credited for adding his own sequences into the training. Do you feel that this change is inevitable and good or do you think that if an art changes then it's not being taught correctly or the student is just not understanding? this question was sparked by Xu Yusheng Yang style, and discussions of Cheng Manching and how the techniques vary from others it seems.
