Book excerpt: Step-by-step instructions on the deadly techniques and tactics of the Vietnamese Cao Dai, which follows an ancient religion that has its thousand-year-old roots in a land often ravaged by warfare. Cao Dai kung-fu stresses both the physical aspects of martial arts and the psychology of tactics. HaHa Lung explains both in detail, including lessons on: Where To Strike; The Five Kinds of Weapons; Subterfuge and Stealth; and Strategy and Tactics.
