Zhēnyáng
Zhenyang lies north of the upper Huai River, in a district named for the ancient Shen River and state. An earlier county seat stood north of the later town; the county was abolished under the Yuan and re-established under the Ming. Its scholars and officials recorded the district's waterways and ancient sites in local histories. In 1723, under the Qing, the county's name was changed from Zhenyang to Zhengyang to avoid the sound of the Yongzheng Emperor's personal name.
