Because I am from the William Cheung branch we do not use this at all. Over the years I have heard many arguments against this being used in any way or at least as a fighting stance. I have read a bit about it but not enough to really understand it. So I am going to ask what is it's uses and how is it used in your system if you use it at all? Cheung practiced Wing Chun under Ip Man I find it hard to understand why it's not used in our system if he had learned it. I have seen a few who come from other branches doing Siu Lim Tau and it seemed to me they left it out as well but I think they used it in other areas.

As a fighting stance I don't see it's usefulness although I have seen some similar techniques in other arts but they were used only as a step in transitioning between stances. One such example was talking about protecting the Femoral Artery during a knife attack. This came from a Ninjutsu technique I read about as a kid. I believe I have even seen Hung Gar people turning into such a stance but again it was a transitioning movement between stances.
