David is a really cool lovely dude and he was a really great help every step of the way, from orienting me in Beijing, to putting me in touch with tai chi masters just to pass the time before I went to my actual month long training up a mountain. Only problem is my stories of the place sound like first draft scripts of 1970s Kung Fu movie. Which is, of course, how it should be.
