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