With the mathematical deduction method and according to the realities, this paper demonstrates the “heaven in the south and earth in the north” in The Book of Changes and explains the philosophical problems that have remained unsolved for years. In this way, it aims to allow researchers to analyze problems with appropriate principles and provide some help for researchers and users.
