Abstract: Zhu Xi advocated that the explanation of Yi-ology should start with the divination and restore divinatory discourse in Zhouyi text, mainly for correcting the deviation of emphasizing philosophical connotation and neglecting divination. He did not intend to oppose divination to philosophical connotation, and denied the connotation of divinatory discourse in Zhouyi. Instead, he regarded divination and philosophical connotation as an integral part of the Zhouyi. He proposed that the explanation of Yi-ology should first be interpreted by divinatory discourse, and then deduce its philosophical connotation. From this point of view, the relationship among Xiang (“象”, images), numbers (“数”), Ci (“辞”, words) and Li (“理”, principles) in Zhouyi from the perspective of divination, that is, there is Li first and then there are Xiang and numbers. The symbols of Xiang and numbers are the expression forms of Li, and the three are inseparable. In terms of hermeneutics, on the one hand, Zhu Xi acknowledged that Zhouyi was a divinatory book, respected historical tradition, and opposed to separating one part of history from the continuum artificially and ignoring textual divination and Xiang and numbers formed in the perspective of divination.On the other hand, Zhu Xi did not just stick to the history, but focused on the openness of textual meaning, took the explanation of “the way of sages” as the goal, and acknowledged the reasonable prejudices, made by Confucius, Wang Bi, Cheng Yi and other scholars, which were close to the principle of Zhouyi in accordance with “reality” or “present” in their respective periods. He proposed a clear and complete explanation path for philosophical interpretation of the Yi-ology, that was, from the perspective of historical development, starting with the divination explanation, explaining the abstract “Yin and Yang” with visual symbols of Xiang and numbers, which completed the interpretation from history to reality, from the Xiang and numbers of divination to the philosophy interpretation of Yi-ology.
