Therefore, the Book of Changes replaces and overlaps heaven, earth and man. Six hexagrams are painted as one hexagram, and each hexagram contains yin and yang hexagrams. It is reasonable to apply the nature of combining rigidity with softness to overlap them, and then tie them up with hexagrams and hexagrams.

The analysis of the biggest mystery in the world and the judgment of change are the "hexagrams" and "words" in the Book of Changes to simulate the changes of heaven and promote the development and changes of things.
