Hello. I recently viewed an instructional on Shanxi Xing Yi. I noticed the persons hand would continue moving after his foot landed. For example, when he did Pi Chuan and his foot landed his hand was still stiking outward. Is this correct for Shanxi style? I study Hobei style from Chen Pan Ling and YWChang lineage and thats a big no no for us. I was just curious what everyones take on this would be.

Perhaps this particular person wasn't any good?

If the hand stops moving forward before the weight of the body arrives, the technique would be less effective; but, it is also true that if the weight and foot arrives too much after the hand that the technique will also have less potential power.

On the video in question, (leaving aside the issue of the the technical requirments of that style of hsing-i) if the hand keeps moving only momentarily after the foot arrives than you can keep in mind the analogy of a log being thrown onto a beach by the action of a wave. The wood being moved by the water does not stop exactly at the moment that the wave crests on the sand of the beach. But being hit by that piece of debris will certainly make an impression on you. ;-}

Most of the Shanxi styles advocate generating force in a wave-like (as Michael pointed out) or whip-like manner.

If you want to crack a whip, the handle (center) has to stop moving to transfer the momentum out of the tip of the whip (hand).

Thanks Michael and Tim. Your statements are sound. It is interesting to hear other views. I appreciate your views...

Some videos I came across on Shanxi XYQ

How does dai xinyi compare to xingyiquan, do you think?
