Chánggě

Changge lies on the central Henan plain, among old river channels and cultivated land. Its name appears in accounts of the Spring and Autumn period, when the settlement belonged to Zheng and was attacked by Song. The Sui established Changge County in 586, with its seat at the place later called Laocheng. Under the Ming it belonged to Xuzhou in Kaifeng Prefecture, and it remained a county of the Xuzhou region through the Qing.
