I have just now received proof that the master I'm studying under is the real thing.
During one of the positions in the movement exercises, my hand was at the wrong angle. The master walked past me, brushed a finger along the back of my hand. A blood vessel burst under my skin right when he did that. So with my hand at that angle, it was unbalancing the flow of blood, and doubtlessly the flow of chi/qi as well.
