Nihao; I'm not sure if my post got through or not as my computer hiccuped just as I was about to post. I am a teacher of Nei gung and have been since the early 1970's. I am willing to share my journey and arts to anyone who might be interested. I learned from another master and he from a master in Northern China. The arts are ancient but not secret. The system of Kung fu I study is called Tao Ping fa. Personnally I can change my weight 60 pounds, make a guitar hum at 10 feet, and move people visably around plus another bunch of stuff.. Kinda' cool when you think about it. Well so long for now. - Sifu
