Since the loss of the Book of Music,scholars have mainly understood music from the civilization of ritual and music,and the Book of Rites has become the most important works for studying ancient Chinese music philosophy.Zhang Zai is good at studying the classics and proposes the"theory of various classics",among which,the Talk of Yue Ji focuses more on explaining the philosophical views of music.Zhang Zai used"recording"to deduce"classics"and"talk-ing"to seek"reason"with expounding and interpreting music from four dimensions:music origin,music path,music use,and music imagery.Music origin is the basic framework of the structure of ritual and music;music path is a moral and moral character that knows change in the face of poverty;music use is the purpose of governing the world by transferring people and promoting political governance;music imagery is an intuitive expression of audio-visual experience.The four dimen-sions of Zhang Zaishi's understanding of music are highly consistent with his views on the heavenly way and the structure of his theory of mind and nature.It not only explains the value relationship between music and human beings,but also tran-scends the historical dilemma of difficult to find ancient music.However,Zhang Zai's"geogenesi"and"anti technology theory"still have room for discussion.
