Grandmaster Jimmy H. Woo. This photo is from a private set he had photographed for his family. In this photo he is holding a pair of butterfly swords. Mr Woo. passed away in 1991. The legacy lives on in the many thousands of lives he touched by teaching his secret family art, Kung Fu San Soo. The International Kung Fu San Soo Association is committed to passing on this powerful art in the way he taught it.
