This Book explores the history, philosophy, and real-world application of Kung Fu San Soo, a martial art designed for self-defense rather than sport or performance.

This book breaks down the core principles of movement, awareness, and adaptability, showing how they apply in modern confrontations—whether on the street, at work, or in everyday life. Through firsthand accounts and clear explanations, it reveals why this combat system has endured for generations: because it prioritizes survival over style, efficiency over tradition, and practicality over flashy techniques. Whether you're new to martial arts or an experienced fighter, this guide offers insights into an approach that values real results over theoretical perfection.
