A couple more books back, from across the ocean:
Yang Tai Chi’s True Narrative – SC216, by Wang Yong Quan.
Wang was the teacher to Wei Shuren. Wang studied at an early age from both Yang Jian Hou and Yang Chen Fu, and this book contains his transmissions he is passing down when in his eighties. This is one of our most popular Tai Chi books when it is available.
Health Enhancing Tai Chi Ruler – TC 818, By Zhang Guang De. This full color book is a cut above many of the others, and actually instructs on more martial movements than are usually taught. Also comes with a nicely done VCD.
