I am studying the Yang Lu Chan basic form of Tai jiquan, from Erles book, he also has a book called Reflex Violence, that teaches instinct fighting and such. People say the Cheng Fu version has taken out alot of the Fa-Jing out of the form, and this is what most people know the derviations of the Yang Cheng Fu, intending for healing. but the Yang Lu Chan form which was made by Cheng Fus grandfather Lu Chan, is about dimmak and has all types of fajing. espeacially in its advance levels.
