There’s just no way to say it other than straight: some styles of Kung Fu are in danger of going away (is it more powerful to say “endangered”?) just like some exotic birds and threatened forests. The Eight Immortals Style has nothing to do with the Eight Drunken Immortals, so popular in Southern China. Here is a survey/DVD showing the essence of this relatively little known style.
Note there is a little historical background from this page (not much but the best we could do) if you are interested in its origins.
