The government of the Song dynasty actively promoted the study of mathematics. There were two government xylograph editions of "The Ten Computational Canons" in the years 1084 and 1213. The wide availability of these mathematical texts contributed to the flourishing of mathematics in the Song and Yuan dynasties, inspiring mathematicians such as Jia Xian, Qin Jiushao, Yang Hui, Li Zhi and Zhu Shijie.
