More Than Techniques

Inner Gate Inner presents Ngo Cho Kun—also known as Five Ancestor Fist or Wuzuquan—as a complete training system in which body, breath, structure, and attention are developed together through disciplined practice.

Rather than treating martial arts as external technique alone, the book reveals the deeper internal principles that govern force, coordination, perception, and disciplined movement.

Rooted in the teachings of Chua Giok Beng and preserved through the Beng Kiam lineage, Inner Gate brings the training logic of Five Ancestor Fist into clear, modern language while remaining grounded in traditional practice.

At its core, the book shows how external form, internal function, breath, structure, and intent become unified through sustained training.
