I am trying to find out what is the difference between Faan Tzi Ying Jow Pai and Shang Tung Eagle Claw. I have found the requirements (name of the forms) for the Faan Tzi system but I can't kind any lists of the Shang Tung system. It would be great if someone could explaine to me the difference but more importantly provide me with a list of the Shang Tung Eagle Claw System.
