One thing you can say with Yao Cheng Guang is everyone who goes over to trainwith him comes back saying these really do fight, and he really does fight - they run a fight gym. I've never heard anyone come back and say otherwise. For me, I can't say that I think they promote Yiquan in exactly the right way, though - the Yaos. I can understand - and it's very, very generous of them to put all the training material up for free - amazingly generous. But their Western students should be advising them, look, you've got to video the sparring, and put that up. Without that, it's just like all the other theory over practice video sets... cheesy China generation game aside...
