Yangcheng was the first capital of the Xia dynasty (c. 2070–1600 BC) of China. In ancient texts, the city was founded by Yu the Great (founder of the Xia),[1] or was his residence.[2] In the Bamboo Annals and Shiben, Yangcheng was located near Mount Song and the Wudu and Ying rivers (close to modern Gaocheng, Henan).[2]
Yangcheng may be located at the Wangchenggang (Chinese: 王城岗) site in Henan. In 1977, An Jinhuai (Chinese: 安金槐)[3] excavated a small east-west oriented walled city at Wangchenggang.;[4] it is dated to the second period of the Longshan era, or approaching the start of the Xia.[5] In 2002-2005, a larger walled city was discovered[4] and radiocarbon dated as the earliest and largest Xia-period site at Wangchenggang.[5]
An and Sun Zuoyun (Chinese: 孙作云) believed the small city to be Yangcheng,[3] and this interpretation remained popular through the rest of the 20th century.[1] [2] One criticism was that the city was too small to be a capital of a major state.[3]
Since its discovery, the larger city has been associated with Yangcheng. The smaller city has been attributed to Gun, Yu's predecessor,[6] [1] although Liu and Chen note that the 100 year difference between the two cities makes this unlikely.[1]
