During the Song Dynasty, Changzhou was classified as an upper-level and military prefecture. Its three  subordinate counties, including Dazu, Yongchuan, and Changyuan, were all designated as upper-level counties. 
According to the local administrative system of the Song Dynasty, it should have been staffed by local officials 
such as the Prefect, the Vice Prefect, prefectural school officers, administrative and clerical staff, and countylevel officials. Based on the historical records of the Song Dynasty and inscriptions of the Dazu Rock Carvings, this article compiles a list of local officials who served in Changzhou, aiming to outline the structure of its 
local bureaucracy during the Song era. The research identifies a total of 77 individuals, including 27 prefects, 3 
vice‑prefects, 5 prefectural‑school officers, 16 administrative and county staff, 16 county magistrates, 1 official in charge of liquor monopoly and taxation, and 9 other prefectural and county officials. However, since He Guangzhen is counted twice for simultaneously serving as County Magistrate and acting Vice Prefect, the final adjusted number of distinct officials in Changzhou is 76.
