Qing would have died of old age long before this time. Plus, a full one third of the masters listed all come from fictional novels. Lin Chong and Yan Qing come from the Water Margin and Emperor Taizu (#1), Han Tong (#2), Zhang En (#3) and Huai De (#11) come from the Fei Long Quan Zhuan ( – “The Complete Flying Dragon Biography”). In addition, most legends place Wang Lang living in the late Ming Dynasty. Xingyi Xingyi is an internal northern Chinese boxing style with five interchangeable fist attacks, based on the Five Chinese elements, and 10 or 12 animal imitation forms (depending on branch).
