Just found out today that Baguazhang has a Quanzhen connection:

Although there are several theories as to the Origins of Ba Gua Zhang, recent and exhaustive research by martial scholars in Mainland China conclude without reasonable doubt that the Art is the creation of a single individual, Dong Hai Chuan. Dong was born in Wen An County, Hebei Province about 1813. Dong practiced local martial arts (which reportedly relied heavily upon the use of open hand palm techniques) from his youth and gained some notoriety as a skilled fighter. At about 40 years of age, Dong left home and traveled southward. At some point during his travels, Dong became a member of the Chuan Zhen (Complete Truth) sect of Daoism. The Daoists of this sect practiced a method of walking in a circle white reciting certain mantras. The practice was designed to quiet the mind and focus the intent as a prelude to enlightenment. Dong later combined the circle walking mechanics with the martial arts he had mastered in his youth to create a new style based on mobility and the ability to apply techniques while in constant motion (heretofore unknown in the history of Chinese martial arts).
