Guǎng'ān
Guang’an was a small administrative centre in the hill country south of the Ordos, on the site of the earlier Dongshan County. The Yuan established Guang’an County here in 1273 and raised it to a prefecture five years later. It belonged to the Kaicheng administration, in a region of loess hills and valleys between the Wei and Yellow rivers. In 1369 the early Ming abolished Guang’an prefecture and incorporated its territory into Kaicheng County.
