In the middle and late Yuan Dynasty, the Yuan government restored a number of prefectures and counties in Sichuan Province. By comparing the historical records and data of schools, ancestral temples and famous officials, we can summarize that from Dade to Zhizheng, the restored administrative districts included three prefectures, namely Rong, Zi, and long, and nine counties of Jingyan, Neijiang, Anyue, Changning, Dazu, Lechang, Jiangyou, Baoning and Tongjiang. Another Shiyang county was newly established. The main reasons for the restoration were the growth of population. These administrative districts shared three characteristics: most of them were established on the basis of the inspection department (xunjiansi), insufficient population and low efficiency.
