Family Taijiquan Illustrated and Explained (陳氏太極拳圖說, Chén shì tàijí quán túshuō) published posthumously in 1933 and the photographed form of his student, Chen Ziming (陳子明, d.:1951), in Inherited Chen Family Taiji Boxing Art’’ (1932). The name, nature, and teachings of this Chen subdivision has been fraught with confusion for nearly a century. Describing the ancestry of his art from Chen Wangting to himself, Chen Ziming referred to practice changes in the Chen Village that separated the art into "old frame" (laojia) and "new frame" (xinjia). He said his book presented the new frame of Chen taijiquan. This was the first published reference dividing Chen Taijiquan into frames, and contemporary books, even one by his teacher, Chen Xin, did not mention frames. Although the art pragmatically tended to be taught among close relatives, there was little or no formal distinction between lineages or branches of teaching methods within the Chen Village, rather Chen Ziming's descriptions match the historical condensation of Chen Wangting's seven-form curriculum into the two-form teaching method begun in the prior century. Tang Hao reaffirmed at some length in the postscript of the same book that by "old frame" Chen was referring to the original curriculum of Chen Wangting. However, Tang and Chen also created confusion. Tang affirmed Chen Wangting as the creator of the original, old frame forms, and he even found mention of three “forgotten" old frame forms recorded in a Chen Family Manual. Despite this, he had yet to grasp the nature of the paradigm shift within the Chen family that caused these old forms to be left behind while preserving Chen Wangting's teachings through the practice of only two old, perhaps updated, forms, the Thirteen Postures and Cannon Fist. Moreover, Tang observed differences between Chen Ziming's Yilu and the Yilu Tang had learned from Chen Fake and with his formative information, assumed these differences to be of archaic origin. Since Ziming called his art "new frame,” and Chen Fake did not, it must have been "old frame." Tang further concluded that the "new frame" must have been created by Chen Youben, Ziming's progenitor. Chen Fake's progenitor, Chen Changxing, must have practiced "old frame" and taught it to Yang Luchan. Regardless of the veracity of his assumptions or reasoning, Tang divided the Chen Family martial art and created three frames out of two. Since then, compelling evidence has led to more complete theories, but confusion persists.
