Chǎngchūn

Changchun occupies a plain beside the Yitong River in central Jilin, where the forested eastern margins of Manchuria meet the grasslands of the Mongol Gorlos Front Banner. Before its formal establishment, the district was crossed by Qing frontier routes and the willow palisade, a barrier intended to restrict movement into the imperial homeland. By the late eighteenth century, however, settlers from Shandong and neighbouring provinces had already crossed this line to farm the fertile black soil.

A Qing survey in 1799 counted 2,330 settler households and more than 265,000 mu of cultivated land. In 1800 the court responded by creating Changchun Ting at Xinlicheng, appointing a resident commissioner under the Jilin general. The new office regulated civilian migrants while leaving land rents to the Mongol princes; its jurisdiction comprised four rural districts and thirty-eight jia. This compromise attempted to balance Manchu frontier policy, Mongol land rights and the reality of rapidly expanding settlement.

The original seat lay too far south and in low ground, so the administration moved north to the market village of Kuanchengzi in 1825. The two names remained in use, and Changchun grew as an administrative and trading centre serving surrounding farms. By 1837 its importance rested on the grain-growing frontier: an office city collecting migrants, taxes and commercial activity where Mongolia, Manchuria and northern China met.
