Comparing to ”Cheng Zhuan,” Zhu Zi's annotations of ”Da Xiang Zhuan” in ”Zhou Yi Ben Yi” have four phenomena to be differentiated, namely, to state that ”Cheng Zhuan” has already been very clearly written, or ”Ben Yi (Zhou Yi Ben Yi)” does not have annotations, but the record in ”Zhu Zi Yu Lei” is the same as the one in ”Cheng Zhuan,” or ”Ben Yi” does not have annotations, and ”Zhu Zi Yu Lei” does not have any record, either; there are 53 divinatory symbols in total. As for another 11 divinatory symbols, they have ”Yi-li (principles),” adopt ”phenomena,” have ”explanations of meanings of words,” or ”leave a question open,” displaying the theory that is vastly diverse from ”Cheng Zhuan.” To analyze it (”Da Xiang Zhuan”) in detail, the obtained result was that, Zhu Zi's purport of researching ”Yi (Change)” was to combine ”Xiang-shu” and ”Yili (principles)” with the intention to establish a new system of theory of ”Yi (Change).” From annotations of ”Da Xiang Zhuan,” the researcher was able to know that Zhu Zi fully deserves the approval, praise, and reputation of ”extensive and profound erudition” among the academic circles.
