Former cities in China

district of Chongqing, China

Khara-Khoto, also known as Heicheng, is an abandoned city near the Juyan Lake in the sum of Bayan Toroi, about 25 km south of the seat of Ejin Banner in Alxa League at the western end of Inner Mongolia, China. Built in 1032, the city thrived under the rule of the Tangut-led Western Xia dynasty. It has been identified as the city of Etzina, which appears in The Travels of Marco Polo, and hence today's Ejin Banner is named after this city.

Hao or Haojing, also called Zongzhou, was one of the two settlements comprising the capital of the Western Zhou dynasty ( BCE), the other being Feng or Fengjing (). They stood on opposite banks of the Feng River (), Feng on the west bank and Hao on the east, and were together known as Fenghao. Archaeological discoveries indicate that the ruins of Haojing lie next to the Feng River around the north end of Doumen Subdistrict () in present-day Xi'an, Shaanxi Province.
