The Dunhuang map, a star map from the Tang Dynasty showing the North Polar region. This map is thought to date from the reign of Emperor Zhongzong of Tang (705–710). Constellations of the three schools were distinguished with different colors: white, black and yellow for stars of Wu Xian, Gan De and Shi Shen respectively. The whole set of star maps contained 1,300 stars.
