Dong Jun (1186—1233) is a famous ancestor of Dong Haichuan. The Dong family is renown for the ancient battlefield kungfu- which Baguazhang earned its reputation in feudal times. The real Dong Haichuan descended from elite military commanders who are also real people- serving the empire with great contributions to Mongolia and Beijing. Dong Jun is the first deputy marshal and Army General of the Yuan Dynasty, in the era of Kublai Khan. In 1232 he participated in the siege of the Battle of Beijing and died during airbending in 1233. Feudal Baguazhang masters deserve honor for their kungfu with accurate context– the modern Baguazhang sports promotions have shifted considerably from the origin systems.
