 For example, Zhaobao t'ai chi ch'uan (趙堡忽靈架太極拳/赵堡忽灵架太极拳) is a branch of Chen-style t'ai chi ch'uan originating from Zhaobao village.The distinction between external and internal (外内) martial arts comes from Huang Zongxi's 1669 "Epitaph for Wang Zhengnan".Stanley Henning proposes that the "Epitaph"'s identification of the internal martial arts with the Taoism indigenous to China and its identification of the external martial arts with the foreign Buddhism of Shaolin—and the Manchu Qing Dynasty to which Huang Zongxi was opposed—may have been an act of political defiance rather than one of technical classification.
