This is a book for those who practice tai chi not only as a health gymnastics, but also as a martial art. The special “combat force” (jin) is usually only mentioned in passing in wushu (gongfu) literature. Master Yang Junming, the author of a series of best-selling books about Chinese martial arts and qigong, wrote the FIRST book in Western languages entirely devoted to this secret section of taiji. In Yang Junming's textbook you will find a complete classification of all types of jin, detailed instructions on their practice and combat use, and also the history and general theory of taijiquan and taiji qigong and commented translations of the most important ancient song instructions on taiji (with original Chinese texts). This book by Master Yang, like all his works, is supplied with numerous diagrams and photographs. The hieroglyphic spelling of the most important terms is given. Not for beginners.
