This is especially evident in its twelve animal structures. But it is perhaps the most rare of the Hsing-I styles found today. HeBei style, in contrast to the ShanXi style, uses much larger frames and appears slower in practice. Its stances are more open than the ShanXi style, and there will be less appearance of fah jing energy in the practice of the forms. The HeBei style is said to delineate from the ShanXi method, but this link remains unclear.
Many people practice the HeBei method today.
And chances are if you meet a practitioner of Hsing-I, they will likely be of the HeBei method over any other. HeBei Hsing-I's expressions of the Five Elements are more simplistic than those of the ShanXi and the Twelve Animal stuctures are much more simplified by and large. The last style, known as the Honan style, is a very simplified style of Hsing-I practiced exclusively by the Muslim Chinese community for generations. It has only Ten Animal structures which are extremely simplistic one or two movement forms only. The Five Elements are present only as concepts in this method, having no movement representations at all.
