Chengchuan Ancient City Site

　　The Huoluochaideng Ancient City Site is located in Haoraochaidamu Sumu, Hangjin Banner, Inner Mongolia Autonomous Region. The ancient city has a rectangular layout, stretching 1,446 meters from east to west and approximately 1,100 meters from north to south. The city walls were built with rammed earth, with a base width of 13 meters and surviving heights ranging from 0.5 to 2 meters. In the central part of the city runs an east–west street about 50 meters wide. At the middle of the western side lies a large architectural platform base, with a coin-casting site located in its northeastern area. The cultural layer within the city is around 0.8 meters thick, from which artifacts such as rope-patterned tubular and flat tiles, concave-cord-patterned flat tiles, diamond-patterned square bricks, and “Thousand Autumns” roof tiles have been unearthed. To the east, south, and west of the city lie burial sites, which are relatively large in scale and include vertical pit graves, brick-chambered tombs, and earthen cave tombs. In 1971, 57 tombs were excavated, yielding gray pottery and glazed pottery items such as storage bins, stoves, wells, jars, and incense burners, along with bronze vessels such as fāng (square wine vessels), hu (wine jars), and “Wu Zhu” coins. Based on the discovery of a bronze seal inscribed “Xihé Nónglìng” (Agricultural Officer of Western River) and other related relics, it is estimated that the site dates back to the period between Emperor Wu of Han and Wang Mang, falling within the jurisdiction of the Xihé Commandery.

　　In May 2006, the Huoluochaideng Ancient City Site was designated as part of the sixth group of Major Historical and Cultural Sites Protected at the National Level by the State Council.
