One notable example is the late master Wang YongQuan (汪永泉） and his student, master Wei ShuRen （魏书人）。 Their style is called Yang-style tai-chi, the Old-Six (杨家太极拳，老六路). It was claimed that their style is the original style, and is quite different from the now commonly called Yang-style as taught by Yang ChengPu (杨澄浦) who, for whatever reason, modified the original form when he moved from Beijing to Shanghai. In other words it is said to be more authentic, more combat-related. I find the six little theory books by Wei most interesting, in particular the book called The theory of Nei-Gong (内功理法).
I find the little book interesting in the following ways:
1. The training method stresses on power-generation through chi as a core competence of tai-chi (corollary: tai-chi movement without this core competency is NOT tai-chi).
2. It covers both chi-generation in stationery form (as in zhan zhuang) as well as chi-execution in moving forms (which is more difficult to do).
3. It makes use of Taoist Neidan concepts in chi-generation (like back three-gates 后三关, use of Du-Mai (督脉) to generate chi-circles etc).
4. It makes use of chi-activated points (as in point-meditation) to form a power structure in both stationery and moving form executions.
Fair to say Master Wei is not the first tai-chi master who "revealed" these principles of authentic tai-chi, but certainly he is the one who did it very systematically and concisely.

PS: This book is an advanced theory book (in Chinese), those without a good foundation in an internal martial art form will likely to find this book rather incomprehensible or irrelevant to their needs.
