For John Yeah. It is probably Master David Chin. He trains very tough students and makes them into good fighters. I was in awe of his students fighting power through stories back in the 80's. In fact it was watching one of his students, while deployed with a Special Ops team in Honduras, that I saw the beauty of Tai Chi and was told I needed to learn it well. I am still on that path... lol. I met Master Chin for brunch a few years back. He is training a former student of mine in Hung Gar and I believe Yang Style Tai Chi. I have not seen him in quite some time but I think Gary has talked with him and he is well. How is Ya Ya.
