Here is SPJ's book that I personally found insightful:
The Treasure Book of Chinese Martial Arts (Volume I): How to master technical fighting and the three golden methods of study (Hardcover)
by Peter Jaw (Author) "What is a technique in martial arts?..." (more)
Key Phrases: golden methods, technical fighting, martial moves, Tong Bei, Tai Ji Quan, Chan Key (more...)
