Ruins of Baitu City

　　The ruins of Baitu City are located in Qingquan Village No. 1, Zhongchuan Township in the southern part of the county, commonly known as Heicheng or Danyang City. The city is situated at the highest point of the Zhongchuan Plateau, backed by mountains and facing a river, occupying a strategic and open location where east, west, south, and north routes converge. Legend has it that General Yang’s forces built the city overnight, which is why it is called Heicheng (Black City). It is also known as Danyang City because it lies north of Phoenix Mountain, a red-clay mountain located to the north of Zhongchuan, with wings extending east and west, resembling a phoenix facing the rising sun.
