Former county of imperial China
Yuanqu or Wanqu County, known as Wanting County after 1086, was a former county of imperial China covering most of present-day Dongming County and the western part of Mudan District in the Heze Prefecture of southwestern Shandong. Yuanqu or Wanqu was also the name of its eponymous county seat. The town was destroyed by a flood of the Yellow River in 1168, and its territory merged with Jiyin County. The ruins of the county seat were rediscovered at Longwangmiao Village in southwestern Mudan District in June 2007 by a team of archaeologists from the district government.
