1.IntroductionrnIn the previous discussion on the logic of thinking of Zhou Yi,we have attempted to examine the evolution from the eight diagrams to the sixty-four hexagrams,in the hope of finding out what it tries to convey to its readers and how it achieves its aim.1 Our conclusion is:Zhou Yi set up a thinking model which deeply influenced the Chinese traditional culture and we can see its influences in today’s China.Moreover,the interpretations of the symbolic diagrams provided by Confucius and his later disciples are not conforming to the gist of Zhou Yi;such interpretations were fabrications by later scholars.
