Astronomy, written by Wei Renshi Shen, has 8 volumes, later called Shi's Classic. Although it was lost after the Song Dynasty, we can still see some fragments of it from the astronomical work Kaiyuan Zhan Jing in the Tang Dynasty today, and sort out a stone catalogue from it, including the equatorial coordinate positions of 28 constellations and 1 15 stars. This is one of the oldest catalogues in the world.

Extended data:

The earliest existing star map depicted on paper is the Dunhuang star map in Tang Dynasty. The star map of Dunhuang in the Tang Dynasty was first discovered in the Tibetan Sutra Cave in Dunhuang. It was stolen by Stan in England in 1907, and it is still kept in the London Museum. It was painted in 940 AD, with 1350 stars on it. It is characterized by cylindrical projection in equatorial region and spherical projection in polar region, which is the same as the drawing method of modern star map. It is the earliest star map in China that uses two kinds of drawing methods: circle and level.
