Yuwang City Site is located at the foot of Zhongtiao Mountain, 7.5 kilometers northwest of Xiaxian County in Shanxi Province.

The site, which is close to the Sushui River, is an alluvial plain formed by the rushing Yellow River; it is also the cradle of the Chinese nation. The city site comprises the big, middle-sized and small cities.

The big city, occupying a large area, has partly been built on Meiling Mountain and has a perimeter of 15.5 kilometers. It is a near-trapezoid shape -- narrow to the north and wide to the south. The city's northern and western walls, and a western section of the southern wall are well preserved with a height between one and four meters. A number of cultural relics from the Spring and Autumn and Warring States periods were unearthed at the site, including a pot, jar, zeng (an ancient earthen utensil for steaming rice), pantile, flat tile, and tile ends with curling-cloud patterns made in the Han Dynasty (206BC-220AD).

The middle city, located in the southwest, is closely connected to the big city. It has a perimeter of 6.5 kilometers and the wall remnant is 5-7 meters wide and 1-4 meters high. Cultural deposits spread inside the city, with a large number of fragments of Han tile ends with curling cloud patterns, carved bricks, pots, bowls, jars, and urns.

The small city is located in the center of the big city, taking a rectangular shape. Near the city are sites of bronze-casting workshops where cultural relics were unearthed, including pottery molds of sacrificial wares and molds of coins, among which the clay mold of the five-zhu coin was the most precious one.

According to historical study, the big city was the capital city of Wei State which was known as Anyi City during the Warring States period (475-221BC); the middle city was a prefecture seat of Qin and Han period (221BC-220AD); while the small city was built in the Eastern Zhou period (770-256BC) and remained in use till the Northern Wei Dynasty (386-534).
