Shaui Jiao does exist in the states. About 20 years ago there were many articles discussing it in "Inside Kung Fu" magazine. Off hand I recall there were schools in Calif., Ohio. I've never run into it myself, but seeing those video's I can see a lot of logic in their art.
I recall reading in the Chinese arts there was a lot of rivarly between the 'Kung Fu' systems and "Chaui Jiao".
Unfortunatly I maxed out on learning new systems decades ago...
