Checked by modern astronomical computation, all the astronomical records in Astro- nomical Chronicle of History of the Song Dynasty are analyzed and counted on the basis of their origi- nal categories. They are then sorted into two types： the type that can be computed and the type that cannot be computed. The rate of mistake is computed, and most mistakes can be known to reflect their original shapes. Other literatures are also looked into for astronomical records of the Song Dynasty.
