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

A Particular Case: Using Elbowing of Biu Jee to Rectify Problem in Rising Up the Spine

Kwan: After several years’ attempt in rising up the spine, I now feel more confused than before. It seems that I can never get it right. Or it’s just due to my stupidity?

Two-centre Operation – Part 2: What are Virtual Centres Representing?

How are the two centre points connected? In the scenarios described in Part 1, the two points are aligned along a supposedly upright, straight spine. This is the most perceived picture. Indeed, this might have been the very important emphasis you have been receiving in your training so far! Nevertheless, let’s examine the last formContinue reading “Two-centre Operation – Part 2: What are Virtual Centres Representing?”

Two-centre Operation – Part 1
