JING Fang's Yi-ology of eight-palace under the vision of philosophy

JING Fang is an outstanding Yi-ologist,also an imposing diviner,with philosophical quality and original thought,Drawing reference with the Confucian theory by DONG Zhong-shu,JING Fang creatively interpreted Yi,based on which established his Yi-ology of eight-palace which reflects JING's academic feature,and made the Yin-yang and Five-element Theory as a core threading through his cosmology;in which for the first time,Five-element Theory was elucidated completely and occupied an eminent position in Yi study;the Dao of Three Powers(heaven,earth and human being) was extended into the Dao of heaven,earth,human being and spirit;the Zhouyi was venerated as the book for rulers' government.The later-generation scholars who make a skin-deep study on JING's Yi-ology,only know the divining usage,but can't grasp the essence of Yi-ology,whose ignorance goes without saying.
