This is the most complete trilingual (English, Spanish, and Korean) Martial Arts guidebook in Tae Kwon Do (TKD), Hap Ki Do (HKD), and Joong Do Ryu (JDR), an original form of Martial Arts created by the author. Over 1,000 illustrations and colored photos span across the entire book alongside step-by- step instruction of the official TKD forms (Taeguek), traditional HKD techniques, and the complete JDR program from beginner level (white) to advanced level (black). It is intended for instructors as well as students, and covers in detail a wide array of the most fundamental aspects of these Martial Arts. The technical aspect is beautifully balanced with the philosophical teachings of Martial Arts, an introduction to Oriental Medicine, and personal insights from the author as a practitioner of Martial Arts for over fifty years. This book, a collaboration of three Grandmasters, can be of great value and excellent reference to any martial artist regardless of the type of Martial Arts practiced.
