1. The Three Kingdoms (220-280) was a historical period that extended from the Eastern Han Dynasty to the Western Jin Dynasty. It was divided into three regimes: Cao Wei, Shu Han, and Soochow. In 220, Cao Pi usurped the Han Dynasty and proclaimed himself emperor. The country was named "Wei" and the history was called Cao Wei. The history of the Three Kingdoms officially began. The following year, Liu Bei continued the Han Dynasty in Chengdu, which was known as Shu Han in history.

During the Second and Three Kingdoms periods, the north was mainly the territory of Wei. Shouxian County was called Shouchun in ancient times and belonged to Yangzhou and Huainan County of Cao Wei. Shouxian County was also the seat of Yangzhou Prefecture at that time. As shown in the picture.
