Cheng Ting Hua is Cheng Yougong’s uncle- Cheng Yougong trained and worked as a shop assistant in Cheng Tinghua’s eyeglasses shop. Contrary to popular belief, many of the Cheng family served as elite instructors to the military (not qigong practice), including Cheng Youlong and Cheng Yougong. Cheng Yougong was the Baguazhang instructor of Zhang Xueliang (son of Zhang Zhuolin who Gong Baotian defended) and many Bajiquan fighters in the early 20th century. Hou Diange, the chief bodyguard of Emperor Puyi has a strong bond with the Cheng family. Cheng Yougong met Huo Diange during service in the late 1920s and frequently exchanged Baguazhang /Bajiquan knowledge. Cheng Qingxun learned Bajiquan from Huo (Yougong’s nephew) and still called Huo Diange “Huo Shishu” (Hou Uncle), well into the late 20th century.
