Hi erdweir, sorry Mt. Hua is in Shannxi, near Xi'an, way west and north of me, very holy mountain--one of the five sacred mountains of China. I don't know much about the Taoist there.
Huangshan, Yellow Mountain, is in Anhui, closer to me. There are Taoists on both mountains of course. I know a little of the Taoists on Huangshan from some reading I've done of DV's and others who visited there last year for a training and shared the experience with me. But I have no direct experience.
Please let me know when you come to visit, Hangzhou is a lovely city and pretty convenient to a lot of other things in China.
