Hi, I am new to the form, and I am looking for answer for these these questions. In the Siu Lim Tao form, can the Fook Sao be used as a strike for application, as I have tried this on the wall bag and I believe it looks like a crane strike? Also after Fak Sao (movement 101 to 102 of the form), we get into the double Lan Sao, I know that Fak Sao is a strike, but is there another application when get back to the Lan Sao? So after Fak Sao we strike outward, when we return back to Lan Sao, is this an application for ridge hand inward as a strike to the back of the head or something? Please advise.
