The standard story that seems to be passed down the Yip Man lines about Ng Mui developing a system for Wing Tsun to beat up an admirer seems to be about the only one around on the internet. Wikipedia offers a different and as far as I can determine unique origin story with Wing Chun having been developed by assassins to get past guards.
there doesn't seem to be much in the way of references for this account though.
Anyway, does anyone know whether there's any real basis for this alternative?
Also, how many other origin stories are there floating around?
