On JIAO Xun's criticism on the theory of transforming among the hexagrams and the establishment of his I Ching learning

JIAO Xun showed his deep insight and contributions in the history of I Ching (the Book of Change) learning by his criticism against the theory of transforming among the hexagrams popular in the Han Dynasty and established another system to interpret Yi. The characteristics of the system are as follows: (1) it is a theory of transformed hexagrams, but not hexagrams transforming, for he, on the basis of the definite and transformed 64 hexagrams, interprets the Text and Commentaries of Zhouyi with the transforming between Yin and Yang, thus it is not about the mutual producing between hexagrams; (2) though this system is diverse and complicated, its contents do not accord with the historical facts, and stretches the meaning to yield to his own rules; (3) JIAO Xun did not solve the problem of the theory of transforming among the hexagrams through ages in the history of I Ching learning after all.
