Yuwang City is the ancient Anyi City. It is said to be Yu's capital of Anyi, known as the "first capital of China". It is located in Yuwang Town, 7.5 kilometers away from the northwest of the county. It is in the hilly area between Qinglong River plain land and Mingtiaogang area.
During the Eastern Zhou Dynasty, it was the capital of the state of Wei. During the Qin Dynasty, Hedong County was set up here. During the East and West Han Dynasties, Hedong County was located here, which was one of the metropolises of economy and culture. In the first year of Emperor Xian of the Han Dynasty, the capital was temporarily established here for half a year. During the two Jin Dynasties, Anyi County was located here. In the first year of Emper Xiaowu of the Northern Wei Dynasty, Anyi was divided into two counties, north and south. The southern Anyi was the site of the Anyi Office in what is now the Yanhu (Salt Lake) district, and the Northern Anyi is now the ruins of Yuwang City. In the tenth year of Taihe, the government set new city around fifteen miles away from the ancient city. In the eighteenth year of Taihe, northern Anyi was moved to the new city. Because of the legend that Xia Yu established his capital in Anyi, it was renamed Xiaxian County, and Xiaxian County thus named. From then on, the city of Anyi gradually fell into ruins. In 1988, the State Council announced it the national key cultural relics protection units.
