Daiwangcheng, as the name suggests, is the capital of the Daiguo State, which began in the Shang Zhou Dynasty and was a small country outside the Zhou Dynasty. Located north of the Taihang Mountains, 20 miles to the south is one of the Eight Mountains of Taihang, the Flying Fox, which undertakes the Mongolian Plateau to the north, belonging to the shallow hilly area, and the Huliu River flows around the city from southwest to northeast, and the dangerous terrain becomes a natural barrier for the ancient city.
The ancient kingdom died in the late Spring and Autumn Period (about 475 BC), and the "History of the Zhao Shijia" states, "Zhao Xiangzi Beideng Xiawu (present-day Caoduoshan, Dai County, Shanxi) tempted the king to make the cook into the copper maple to eat the king and his followers, and the Yin Order Zairen each attacked the king and the subordinates, and then xingxing the soldiers to ping the land, and feng Boluzi (Zhao Xiangzi brother) as the substitute king." Since then, daiguo has become the dai county of the Zhao kingdom.
As for the Zhao Wuling King Hufu riding and shooting, it is also with the help of the geographical advantage of dai county adjacent to the nomads. The rapidly powerful Daiguo destroyed the ancient Zhongshan Kingdom in one fell swoop and opened up the north-south communication line. The border of the Zhao state reached Handan in the south and Dai County in the north, becoming one of the "Seven Heroes of the Warring States". In the last year of the Warring States period, Zhao Gongzi Jia led hundreds of people from the clan to run to the throne and became the acting king. In 222 BC, "Wang Ben destroyed Yan, and also attacked the Dynasty, and Wang Jia of the Yu Dynasty". Daidi became one of the thirty-six counties of the Qin state.
In the early years of the Western Han Dynasty, Liu Bang took his brother Liu Xi as the acting king and made the capital wangcheng. The following year, the Xiongnu attacked the dynasty, and Liu Xi abandoned the country and killed himself. However, the location of the daidi was important, and the Han court took Liu Heng, the son of Gao Zu, as the acting king, that is, the future famous Emperor Wen of Han. Liu Heng decided to move the capital to Jinyang (Taiyuan), and from then on, the imperial capital became the county seat of Dai County. Then in the second year of the Northern Zhou Dynasty (580), Ulju was established and the city of Ulju was built, which is now the county seat of Wei County. Daiwangcheng gradually became a poor and remote area.
Today's Daiwang Town, which is the site of the ruins of the Imperial City of the time, is still surrounded by continuous rammed earth walls, with a residual height of 3-12 meters, intermittently nearly 10 kilometers, and there are a large number of Han tombs distributed around the city site, which shows the prosperity of the Imperial City of that era. In the town, you can also see many old temples and houses, and the earthen walls and fort gates of the fortress still tell the history of this ancient city outside the Seychelles.
