well I do not agree with you that all qigongs are the same - or that all these divisions are somehow artificial.
I don't want to argue about it but let's put it this way - why do you think so many qigong masters were experts in several systems? Why didn't martial arts masters in china just focus on medical qigong? Do yoyu really think people who know medical qigong only can apply qigong to chinese martial arts? Seriously. think about that. For real. Really think about it. Why is it that so many masters of high level chinese martial styles studied medical & martial qigong methods? do you think you are more informed than they were> Let's just consider wudang mountain(I won't go into hua shan, kunlun mountains, songshan(shaolin) etc.) - why did the monks learn several different qigong methods - including martial & medical systems? Is it because they were not as well informed as you are? Is it because they didn't know SFQ?
Seriously. Think about the history of qigong, chinese buddhism & daoism, and chinese martial arts before you speak.
I'm out of SFQ for now - if I want to come back I'll stop by.
