The State of Wei, founded in the early Zhou Dynasty, had its capital at Chaoge. Qicheng was a small city located in the heart of Wei.
In 629 BC, Duke Cheng of Wei moved the capital to Diqiu (present-day Puyang), which served as the political, economic, and cultural center of Wei for 388 years. Later, as the state's power declined, Qicheng became a key military stronghold on the northern border.
The name "Qi" appears more than 40 times in the Spring and Autumn Annals. The *Zuo Zhuan* records that from 626 BC to 531 BC, feudal lords and high officials from various states held seven alliance meetings in Qicheng. The ruins of Qicheng contain a 20-meter-long, 16-meter-wide, and 4-meter-high platform, a rammed-earth platform built during the Spring and Autumn Period.
The Qicheng ruins are located in the southern part of Puyang city. The city wall has a circumference of 1520 meters, with the highest remaining section reaching 8.5 meters and the widest section 16 meters. There are gaps of 30-40 meters wide on all four sides, likely remnants of ancient city gates.
