Shuiding (Chinese: 水定镇; pinyin: Shuǐdìng Zhèn; Uyghur: سۈيدۈڭ بازىرى), formerly Suiding (Suiting) (Chinese: 绥定; pinyin: Suídìng) is a town in the Ili Kazakh Autonomous Prefecture, Xinjiang Uyghur Autonomous Region, China and the county seat of Huocheng County.
Suiding (綏定城) was built in 1762 during the reign of the Qianlong Emperor after the Revolt of the Altishahr Khojas was pacified.
Huiyuan suffered severe damage during the Dungan Revolt of 1862–77 when the besieged General of Ili, Mingsioi, blew himself up in his palace rather than surrender to the rebels, and during the Russian occupation that followed between 1871-81.
The 1911 Encyclopædia Britannica described "Suidun" as "a military town, with provision stores, an arsenal and an arms workshop.
"[1] Unlike the city of Yining, originally known as Ningyuan (宁远城; Níngyuǎn Chéng), which has always remained the commercial center of the region, the 19th century Huiyuan/Suiding was mostly a fortress and an administrative town.
