Yecheng

Yecheng, usually called Ye, was an ancient Chinese city in what is now Linzhang County in Handan, Hebei, next to the border with Anyang in Henan. Duke Huan of Qi first built it in the Spring and Autumn period, and by the Warring States period it belonged to the state of Wei. Under the Han dynasty it was the seat of Wei Commandery and an important regional center. After Han rule collapsed it served as the military headquarters of the warlords Yuan Shao and Cao Cao, and under Cao Cao it became a political and economic hub of northeastern China in the Three Kingdoms period. During the Sixteen Kingdoms and the Northern dynasties it was the capital of the Later Zhao, Ran Wei, Former Yan, Eastern Wei and Northern Qi.
