A little while ago I bought some DVDs at the Xidan Bookstore. One of them was “Stance Training”, apparently one of four by Zhang GuangYu. The DVD drive on my laptop is playing up a bit, so the video and sound are pretty choppy, but the DVD actually appears to be really, really good - just what I imagined yiquan to be like… I’m just wondering if anyone out there knows anything about Zhang Guang Yu, because Google turns up nothing apart from the DVDs, as far as I can tell…
