In this classic book, Black Belt Hall of Famer William Cheung unravels the mysteries of the elusive energy known as chi. The wing chun kung fu master recommends exercises to increase and direct the flow of chi and explains how chi affects the body. He also covers the philosophy of the yin-yang symbol, pressure points and the 32 meridians, the principles behind dim mak (the often-misunderstood “death touch”) and more. This book is a must-read for not only kung fu students but also practitioners of other martial arts — and anyone interested in Eastern philosophy.
