Introduction to the evolution of Dingyuan County;

Dingyuan County was a land of Huaiyi in ancient times and belonged to the State of Chu in the Warring States Period. When Qin established the county, it belonged to Yinling (Gucheng Village, Backing Township, Dingyuan County) and Dongcheng (Sanguanji County, Da Qiao Town, Dingyuan County) under the jurisdiction of Jiujiang County.

In the Western Han Dynasty, there were Yanling County, Dongcheng County, and Quyang Houguo County (located in Longtouba, Fengyang County), all of which belonged to Jiujiang County. Wang Mang changed Dongcheng to Wucheng, Yinling to Yinlu, and Quyang Houguo to Yanping Pavilion. In the Eastern Han Dynasty, the old name of the Western Han Dynasty was restored, and Yanping Pavilion was renamed Xiquyang. Dongcheng, Yanling and Xiquyang counties all belong to Jiujiang County (governing Yanling).

In the fifteenth year of Yongping (72), Dongcheng was changed to Xuzhou Xiapizhou, and the establishment of Dongcheng and Yanling counties was cancelled in the Three Kingdoms Wei Dynasty, and it was changed to Xiquyang County in Huainan County. The establishment of Dongcheng and Yanling counties was restored in the Western Jin Dynasty, and it still belongs to Huainan County. The organizational system of the Eastern Jin Dynasty is the same as that of the Western Jin Dynasty.
