Reprint of the Expanded Edition of "Dai-style Xinyi Liuhe Quan: Essential Techniques for Combat" This book is a comprehensive guide to Dai-style Xinyi Quan, a martial arts system passed down through generations, encompassing Xinyi Liuhe Quan, Xingyi Quan, Yiquan, and Taiki-ken. It covers the history, theory, and training methods (Dantian exercises, footwork, techniques, applications, and Mo Shou) of these martial arts, along with detailed explanations of specific techniques, secrets, and hidden teachings, accompanied by illustrations and easy-to-understand diagrams.
