Only Wu Yu-hsiang (武禹襄; 1812–1880), a student of Yang Luchan and the eventual founder of Wu (Hao)-style t'ai chi ch'uan (武/郝氏), was known to have briefly studied the Chen Family small frame system under Chen Qingping (陳清平 1795–1868). This situation changed with the fall of the Qing empire when Chinese sought to discover and improve their understanding of traditional philosophies and methods. In 1928, Chen Zhaopei (陈照丕; 1893–1972) and later his uncle, Chen Fake (陳發科, 陈发科, Chén Fākē, 1887–1957) moved from Chen village to teach in Beijing. Their Chen-style practice was initially perceived as radically different from other prevalent martial art schools (including established tai chi "traditions") of the time. Chen Fake proved the effectiveness of Chen-style t'ai chi ch'uan through various private challenges and even a series of Lei tai matches. Within a short time, the Beijing martial arts community was convinced of the effectiveness of Chen-style t'ai chi ch'uan and a large group of martial enthusiasts started to train and publicly promote it. The increased interest in Chen-style t'ai chi ch'uan led Tang Hao (唐豪; 1887–1959), one of the first modern Chinese martial art historians, to visit and document the martial lineage in Chen Village in 1930 with Chen Ziming. During the course of his research, he consulted with a manuscript written by 16th generation family member Chen Xin (陳鑫; Ch'en Hsin; 1849–1929) detailing Chen Xin's understanding of the Chen Village heritage. Chen Xin's nephew, Chen Chunyuan, together with Chen Panling (president of Henan Province Martial Arts Academy), Han Zibu (president of Henan Archives Bureau), Wang Zemin, Bai Yusheng of Kaiming Publishing House, Guan Baiyi (director of Henan Provincial Museum) and Zhang Jiamou helped publish Chen Xin's work posthumously. The book entitled Taijiquan Illustrated (太極拳圖說 see classic book) was published in 1933 with the first print run of thousand copies. For nearly thirty years, until his death in 1958, Chen Fake diligently taught the art of Chen-style t'ai chi ch'uan to a select group of students.
