In China Taoist culture and ancient Han astronomy books, Beidou nine planets has names: Shu Tianxing, Tian Xuanxing, Tianjing Star, Tianquan Star, Yuheng Star, Lvyang Star, Yaoguang Star, Cave Star and Hidden Star. Originated from Han people's natural worship of ancient stars. In the Song Dynasty, the Taoist gobbledygook "Seven Stars Cloud" and "Sun, Moon and Stars System" both mentioned the existence of the Big Dipper and its auxiliary stars, and called it the nine planets. The poem "Bu Xu Ci" written by Xu Xuan in the Five Dynasties says: "Take all the clothes and multiply by three elements, spinning and crawling nine planets". Later, these two stars gradually disappeared and became "seven now and two hidden", so today there is the saying of the Big Dipper.
