Does anyone know whatever became of Chinese qigong master Yan Xin? When I check what appears to be the offical Yan Xin webpage ( http://yanxinqigong.net/ ) and elsewhere, there seems to be no info on Yan Xin after about the early nineties or so. He seemed to be actively promoting his qigong through workshops and that sort of thing in the late eighties and maybe early nineties, but there seems to be next to no info about him after that period?
