Biu Jiu Speedy?: Outer Linear Speed vs Inner Angular Acceleration

When we say to do Biu Jee one should move speedily, it can mean different things. In one scenario of “speedy” elbowing (Common mechanism 1 in the post Kneeing Elbow in Biu Jee – Tangential Force and Sucking in Whirlpool Analogy), the arm does so by travelling at high speed throughout a very noticeable distance.Continue reading “Biu Jiu Speedy?: Outer Linear Speed vs Inner Angular Acceleration”

Swirling: Active Rib Cage Circling Shoulder Joint Socket

This post is a continuation of the post Kneeing Elbow in Biu Jee – Tangential Force and Sucking in Whirlpool Analogy, which ends with the pending question: What is still lacking for creating the whirlpool effect? Recall the 5-gear analogy put forward in The Book of Wing Chun (Vol. 1, pp. 225-229; also refer toContinue reading “Swirling: Active Rib Cage Circling Shoulder Joint Socket”

Kneeing Elbow in Biu Jee – Tangential Force and Sucking in Whirlpool Analogy

The consecutive elbow-kneeing is an iconic move of Biu Jee. (“Kneeing elbow” is translated from a term in Chinese used by Grandmaster Chu in his Book of Wing Chun.) It refers to the elbowing moves in the first few parts of Biu Jee, and often serves as the preparatory drill before actually practising the BiuContinue reading “Kneeing Elbow in Biu Jee – Tangential Force and Sucking in Whirlpool Analogy”

Weak Bong Sau Due to Weak Forearm – Clear-through, Curve to Point

When practising Bong Sau, it is typical to point the fingers forward along your centreline. This is something most emphasised when your Bong Sau doesn’t seem to stand up incoming force at the forearm and your instructor repeatedly guides you to point it more focused, and more intently. Have you ever had such experience? DidContinue reading “Weak Bong Sau Due to Weak Forearm – Clear-through, Curve to Point”

The Wrapping Intent – Wrapping around the Contact

What I am trying to depict in this post may be considered to be too imaginative, prone to be criticised as unrealistic and in fact unnecessary. However, it appears to me as something can’t be omitted should the exposition of the point-linked mechanism be completed, as it manifests the gist and essence of the mechanism.Continue reading “The Wrapping Intent – Wrapping around the Contact”

What’s Happening at Forearm Contacts? – Microscopic Deflection

“Why are multi-directional forces a desired advantage? When the opponent exerts a strong force on your forearm, at any particular moment the force is strong in one direction only. However, at that same particular moment your contact with him is rich in diverse forces – some are in directions appropriate for containing his unidirectional force,Continue reading “What’s Happening at Forearm Contacts? – Microscopic Deflection”

Illustrations – Project, Converge, Elbow Pin, Multi-directional Forces

I try to illustrate by drawings what have been covered in some previous posts, namely, How to Focus? Converging for Control Zone – Amoeba Membrane Analogy, What is Elbow Power? – Solid and Immense to Opponent, Light to You, and Multi-directional Forces in the Arm – Pinning Elbow Tip in Space. Two movements in the second partContinue reading “Illustrations – Project, Converge, Elbow Pin, Multi-directional Forces”

Multi-directional Forces in the Arm – Pinning Elbow Tip in Space

In the last post we explored how elbow power represents the body momentum, and proposed that its properties are preferably described as solid and immense, in contrast to the idea of heaviness people usually aim at. In the end of the post I highlighted that such elbow power is foundational to multi-directional forces in armContinue reading “Multi-directional Forces in the Arm – Pinning Elbow Tip in Space”

How to Focus? Converging for Control Zone – Amoeba Membrane Analogy

Forward focus, aiming forward, pointing, facing and heung (in Cantonese)…… All these terms may sound familiar to you as early as you first started your Wing Chun training. In most cases they intend to refer to the same thing, one of the core principles of Wing Chun, which is essential due to the following. YouContinue reading “How to Focus?

From Centre of Mass to Linked Point Structure – QnA (Harry, Scott)

Harry Leung (extract): …… I would appreciate if you could explain CST’s wing chun of COM (does it feels like a ball spinning inside our body?), generally on how it is developed and used and whether it is always spinning or spins it only when we want to execute a movement eg, liking walking? orContinue reading “From Centre of Mass to Linked Point Structure – QnA (Harry, Scott)”
