Suining basically was a part of former Suiling (睢陵) county by the Han. The seat of the Suiling was relocated to present-day Suining during the Three Kingdoms,[1] and Suiling was merged into Suqian later. In 1218, it became a separate county seated at the old walled city of Suqian,[2] and named "Suining" (literally: Bring peace to the Sui basin).[3] The county was defunct in early Yuan, but restored in 1275. It was under Pizhou of Huai'an until Pizhou became a part of Xuzhou in 1733.
The ancient city Xiapi, where Pizhou used to seated is located in Gupi (古邳) Town.[3]
Administration
Suining County is divided into 3 subdistricts and 15 towns.[4]
