-Pa Kua Boxing or Baguazhang -The history of Baguazhang as an internal form of martial arts is unclear. The most acceptable theory suggests that Dong (T’ung) Hai-ch'uan (1798-1879) learned Bagua from a Daoist named Dong Menglin of Jinhua Mountain in Anhui Province. After rising in fame in Bejing (Peking) Dong (Tung) was challenged by Kuo Yen-Shen of Hsing-i ch’uan both were equally matched and stalemate resulted. A pact between these two masters ensured that their future students were to be instructed in both internal styles. Notable students include Yin Fu, Ch’eng T’ing-hua, Ma Wei-chi, Liu Feng -ch’uan and Shih Liu.
