Why is Shanxi called "the land of Sanjin"?
At the end of the Spring and Autumn Period and the beginning of the Warring States Period, three vassal states from the State of Jin all made their capitals in Shanxi Province.
in the 16th year of king ding of Zhou (453 BC), Zhao, Wei and Han, the Qing clan of the state of Jin, were divided into three parts, which was called "three parts divided into Jin" in history. Zhao, Wei and Han were divided into three kingdoms, which became actually three vassal states. In Shanxi, Zhao governs the central, northeastern and southeastern parts, Wei governs the southwestern and southeastern parts, and South Korea governs the southeastern part and the southwestern part.
At first, the capital of Zhao was in Jinyang (now northeast of Jinyuan District, Taiyuan), the capital of Korea was in Pingyang (now Yaodu District, Linfen), and the capital of Wei was in Anyi (now north of Xiaxian County, Yuncheng). Later, with the expansion of its territory, it moved to Henan and Hebei. In the twenty-third year of King Weilie Zhou (43 BC), the Emperor of the Eastern Zhou Dynasty officially recognized Zhao, Wei and Han as vassals, and the history of China began to enter the Warring States period. Shanxi belongs to Zhao, Wei and Korea.
