Jeong Yak-yong presented the four methods about the transition of the Kua the Versachlichung(or symbolic image) of things, the piling structure of the Kua and the change of the Hsiao(爻) as a standard interpreting methods of the book of Changes 『周易』 in the Four Commentaries on the Book of Changes (周易四箋). In this book, he_agreed that Chu Hsi`s interpretation of the Book of Changes(周易) not only played an important part in correcting the error of the tradition of the science of divination, but systematized the interpreting method of the science of divination exceeding the limit that even Chu Hsi didn`t explain the logic clearly. His theory of interpreting I (易) established the principle that explain all conditions about the transition and application of I(易). It explains all varieties of symbolic images and transitions including I(易) to well-ordered principle clearly, so it is similar to get the original functions working wholly by repairing the trouble and accounting for the structure and functioning principle of an intricate machine which has various functions.
