Chenghe Site

　　The Chenghe Site is situated in Shuangcun Village, Hougang Town, Shayang County, on the northern shore of Lake Chang, with the Chenghe River running southwest of the ancient city. The site has an irregular oval layout, covering an area of approximately 700,000 square meters.

　　The site was discovered in 1983 and originally named the "Caojiawan Site." It was renamed the Chenghe City (Site) in 2006. The northeastern side of the city is naturally bordered by a high ridge that serves as a natural city wall, while the remaining sides were constructed from rammed earth on flat ground. The outer walls of the city are relatively steep and straight, while the inner slopes are gentle. There are gaps in the southeastern corner of the city, the western end of the northern wall, the central part of the western end of the northern wall, and the middle section of the southern wall. Outside the northwest, south, and west walls, there are moats approximately 30 to 50 meters wide. The moat outside the natural ridge in the northeast is not clearly defined, and the northwestern part of the site is slightly inwardly recessed. The cultural attributes of the site are attributed to the Qujialing and Shijiahe cultures.

　　The discovery of the Chenghe Site not only enriches our understanding of early ancient cities in the middle reaches of the Yangtze River but also provides invaluable material for studying the relationships between early urban sites in this region, exploring the layout of prehistoric settlements, and investigating the origins of civilization in the area.
