This book explores a practical martial art developed in southern China, focusing on close-range combat and efficient movement. Unlike many traditional fighting systems, it was designed for real-world self-defense rather than sport or performance. The content examines core principles like centerline control, simultaneous defense and attack, and using structure rather than brute strength. It discusses how the art adapts to modern needs while staying true to its roots, covering training methods, common applications, and realistic pressure testing. The writing avoids exaggeration, instead presenting honest assessments of what works and what requires adaptation in contemporary scenarios. Readers will find straightforward explanations of techniques, training approaches, and how to develop practical skills for self-protection. The material balances respect for tradition with practical considerations for today's world, making it useful for both beginners and experienced practitioners.
