PROTECTING HAND – WU SAU

Overview
Wu Sau is the quiet guardian of Wing Chun, a simple, compact hand shape that protects the centreline while staying soft, alert, and ready to react. It is not a block, nor is it passive. Wu Sau holds the inside line with relaxed intent, maintaining perfect positioning for transitions into defence or attack.

Purpose of the Technique
The aim of Wu Sau is to provide a stable, neutral guard that keeps the body safe and poised for movement. Wu Sau teaches discipline, structure, and the ability to stay relaxed without collapsing.

Structure & Positioning
Wu Sau sits slightly forward of the chest with the elbow down and the wrist aligned. The position is compact, not extended, not retracted. The hand stays alive, ready to rotate, extend, or transform. The shoulder remains relaxed, and the pressure remains light. This shape offers protection without restricting mobility.

Using Wu Sau Under Pressure
Wu Sau responds instantly to changes. If pressure comes inward, it can transition into Tan Sau, Fook Sau, or Pak Sau. If the line opens, it becomes a punch. If force drops, it can become Bong Sau. Wu Sau is the base position from which all Wing Chun defensive shapes grow.

How It Connects to the System
Wu Sau appears throughout Siu Nim Tao, Chum Kiu, Chi Sau, and realistic application. It is central to the defensive cycle of Tan–Bong–Fook and is used constantly when resetting or controlling the inside line. Wu Sau embodies Wing Chun’s principles of centreline protection, relaxed readiness, and efficient movement.
