Don’t really have one. Don’t know him. Although I have seen his name on the back of the Pa Kua Journals for as long as I can remember. I want to hear what others think, hence the reply to put the thread back on top. 
He states that he is a disciple of Feng Zhiquiang is this true?
BTW, how many disciples does Master Feng have anyways?
Thanks for the info Wujidude. To confirm Harrison has gone to China multiple times this last year. Maybe I will ask him about Jerry. The reason I ask is their is a medical qigong text book written by him . I’m curious if its any good.
Peace
