On The Collected Annotations of the Zhouyi by LI Dingzuo

The Collected Annotations of the Zhouyi by LI Ding-zuo in the Tang Dynasty,the earliest existing records of the Han Yi works,has an unmatched documental value.As a central manifestation of interpreting versions of the contemporary academic thought,The Collected Annotations confronted The Rectification of the Meanings of the Zhouyi by KONG Ying-da with image-number Yi-ology since the Han Dynasty and Xin yi(a way of interpreting Yi-ology with both image-number and philosophical connotation by CUI Jing in the Tang Dynasty),reflecting a research tendency at that time;LI's annotation keenly criticized the philosophical idea of metaphysical Yi-ology,such as WANG Bi's idea of taking non-existence as root,and became an important tie connecting the studies of Yi-ology in the Han and Song dynasties during the development of Yi-ology philosophy.
