This book, first published in Chinese in 1963, is still considered a valuable primary source by all fans of gymnastics and the martial art of Tai Chi (both in the PRC and in other countries). Its author was a student of the famous master Yang Chengfu (1883-1936), who created the modern standard of Yang style. Detailed practical instructions are based on more than twenty years of direct training from the master. The drawings that accompany the text were made from authentic archival photographs of Yang Chengfu. The main goal of this book is to explain the basics of Tai Chi Quan as a system of self-improvement and lay the foundation on which each practitioner should build his own skill.
