Ji Cheng is now in Yanzhou, which is the city.

After Wang Ziping moved the capital to Luoyi in 770 BC, it was customarily called the Eastern Zhou Dynasty. The Eastern Zhou Dynasty is divided into two stages: the Spring and Autumn Period and the Warring States Period. After moving eastward, the royal family declined, from "the master of the world" to a vassal sheltered by vassal States.

After a long period of swallowing, dozens of countries merged into seven big countries in the Spring and Autumn Period, which was called the Warring States Period in history. It started in 475 BC and ended in 22/kloc-0 BC, when Qin unified China. Beijing is the seat of Yan State, one of the seven chivalrous men. Ji Cheng is the capital of Yan State.
