Locking

My teacher is good at locking my arm when doing single hand pushing hands. By locking, I do not mean those locks used in judo or other martial arts, in which arm locks are used. I am referring to my teacher putting his wrist on my wrist, and I am unable to move my arm without locking myself.

The feeling is this. He puts his wrist against mine. He doesn't push or pull, or do anything at all. Yet when I try to use peng to move his arm, I find that I cannot move his arm. The more I try to turn my kua to move my waist so as to peng, the more I find myself locking my arm against my body. And of course, using brute force does not help at all. My teacher simply uses whatever force I bring against him to put me off balance.

When I ask my teacher how to counter this, he tells me to peng. But of course, he says my peng is not able to move his arm yet because my kua is still not able to turn properly. Basically, the kua of both legs must be able to turn fully before a person can peng properly. Otherwise, there will still be a bit of ding (resisting force) left, which is why my teacher is able to lock my arm without having to do anything more than putting his wrist against mine.

I guess it is back to practising lan que wei...
