Why are the number of nine squares in each square equal?

Jiugong, an ancient astronomer in China, divided the Heavenly Palace into nine equal parts: Gan Palace, Kang Palace, Geng Palace, Gong Zhen, Zhong Palace, Gong Xun, Gong Li, Gong Kun and Dugong. Observing the movements of the seven obsidians and the stars from the ground at night, we can know the direction and season.

Through the combination of Taoism, celestial phenomena, eight diagrams, Luo Shu, 24 solar terms, space and numbers, a basic pattern and framework have been formed. This model and framework are multidimensional. When measuring, we put the specific time in this pattern and judge the rheological law of everything in the universe at the specific time and direction with a certain point as the center, thus providing the basis for people to choose the trend and time of behavior.
