Just wanted to share this video of one of my class mates from the early 90's. Stan was a strange kid, about 17 in this video, I remember him having some mental development problems that made him a bit shy and awkward in conversation, but he was fun to practice with.
And here is Shifu Qing Zhong Bao, George Xu's main teacher before George left China around 1980. He is 95 years old in the video. Lanshou, the system he is a master of, and the one Stan is demonstrating above, is considered a mixed internal and external system. Whatever right? Looks like it is pretty good for health in old age as well as training young people for maximum versatility.
