What kind of concept is "the sky is round and the place is round"

Chinese traditional culture advocates "harmony between man and nature" and pays attention to imitating nature. The principle of "heaven is round and place" advocated in geomantic omen is a special annotation to this world view. The circle is the knowledge of Taoism in China, and the square is the ideal realm of Confucian personality cultivation in China. The mutual tolerance of circles and squares and the complementarity of Confucianism and Taoism constitute the main spirit of Chinese traditional culture.
