Wing Chun was the name of the nun who the style was past down to from another nun Ng mui. So its come through two sisters. The nuns trained in it were formidable aversaries for not only the town bullies and war lords men but the thieves and soldiers who would try it on with them too.
The style is very balanced between thehard styles and the soft stlyes. It came originally from a mixture of all the animal styles from the south of China .
When the manchuians (i think it was) from the north took over goverment in the south. the Shao lin temple was the secret meeting point of the planned revolution. Many masters from the south joined in and all placed everything they knew and talked it out how to form a newart thatcould be taught faster and had the beest from each style in order to overthrow the goverment.
A spy working both sides sold them out and they were all surrounded and all burned along with the original temple. the only one to escape that had the knowledge of all the mixed martial arts from all the past meetings that were to be used to train a new army into revolt was a lady nun Ng mui who later in life past it onto the adopted girl of the monastry who was named Wing Chun (which means litterally "hope for the future").
