Everybody knows Dong Hai-Chuan, the founder of Bagua Zhang. He taught many students in Beijing and in Hebei Province for many years. His two top students were Cheng Ting-Hua and Yin Fu. They later separated to spread his teaching, one student went to teach Bagua in East Beijing and one went to West Beijing. Although each student had added their own unique technique to his teachings, the essences of Dong Hai-Chuan's teachings are sill preserved. This video shows part of Cheng Ting-Hua's Swimming Dragon form.
