In Chinese tradition, Polaris has extraordinary significance. The ancients knew Beidou and polar stars as a whole, called "Douji". Douji is at the center of the rotation of the starry sky, and the stars rotate around it, as if it were the master of the sky. However, the ancients used the Beidou dagger to determine the seasons with four fingers. Beidou became the maker of the order of heaven and earth. Spring, summer, autumn, and winter harvest seemed to come along with the direction of the Beidou, and Beidou became the center of everything in heaven and earth. ^[4]
