Hello
First, sorry my bad english.
The Choy Li Fut set is Siu Mui Fa, Doc Fai Wong´s version, but mixed with a Lee Koon Hung flavor, specially some combo (Chi Nao - Poon Kiu - Chap and others), and some movements diferents.
This set isn´t form from GM Wong Gong (Kong Chow brach), is from GM Hu Yuen Chou (King Mui branch). GM Hu Yuen Chou learned this set from GM Chan Yiu Chi.
Un saludo.
