I teach the Gao style system as taught by Luo de Xiu, but occasionally add other Nei Gung elements, plus some Tai Chi, Hsing-I or even Eskrima to illustrate points as seems necessary.
Class usually consists of a little standing meditation, ji ben gung, and either circle walking practice or straight line forms with fighting applications.
Class has been running for about a year now. We are just about to start on Tienjin circle form #6, and Line 1.5.
Beginners are welcome to join at any time, as are continuing practitioners.
