I wouldn't waste time what others said, it sounds like they don't know, what I told is what was. That is why our Art is in trouble, few learned the things/facts they should have, then they say strange things that don't make sense. One Master said that there was no Nam Pi, it was made up, I guess I should go in and throw all those Nam Pi lessons away. That sounds like a fox hunt, "Talley ho the fox", I am sure he was trying to say Tsoi Li Ho.
I chose a poor word "system", group would be better, all he knew was our Art, from my research I don't even think Ho was a proper use, all Jimmy was saying is those three are the families that our Art came from. Chan Sai Mo, the son of the man who taught Jimmy said Jimmy only knew Choy Li Fut when he left China.
If your instructor said Ah Soo he probably studied with a Woolsey student unless he was old enough to study with Frank.
I am afraid that when us old timers go, there will be no one to correct these stories/facts, this is why I have researched the information for my book. Several people who I have interviewed have died since the interviews.
