Grandmaster Wong explains that high phong sau is normally not used in our school due to its innate weaknesses

A unique feature of our school is that whenever we practice kungfu, we are also practicing chi kung and meditation. Chi sau, of course, is no exception. Course participants enjoy some interesting chi flow followed by standing meditation after chi sau practice. Grandmaster Wong then answers some relevant questions. He replies that high phong sau, which is quite common in some Wing Choon schools, is normally not used in our school because there are some innate weaknesses.
