Hi Wolfman! Yes, I practice baji as well, but only a little. My teacher is from northeastern China. So far, I have only studied the big baji form. There are a lot of other forms in the system, such as the small baji form, two-men sparring form, six big opening (liu da ghaai), and others. In comparison to other styles that I study, movements in baji are a lot simpler, but very direct and effective for short-distance combat. A lot of emphasis is placed on developing jing. I met a taiji/baji master from Beijing who told me that every stance in baji can be practice individually as pole standing exercises to develop different jing.
