The Bear system belongs to the Gen trigram, which is the youngest of the Yang trigrams and known as the youngest brother. As such, it is strong, but does not fight in a dominant manner. It is the art of snatching victory from defeat, attacking from a retreat, or fooling an opponent by being seemingly simple. It is ideally suited for people who are heavy set, large in frame and/or girth, stocky/heavy and are capable of using their body weight to advantage. A generalization is that the Bear uses a heavy, rotating force to neutralize the opponent while attacking from an unexpected direction.
Bear was the favorite animal of Yin Fu’s student, Ma Gui, who according to legend also learned the Crab form from Dong Haichuan.
