Wei first appeared in the Spring and Autumn Period and the Warring States Period, and Cao Wei in the Three Kingdoms was the closest to the Western Wei Dynasty. Cao Wei was followed by Sima Jia's Western Jin Dynasty, but the unification was really short-lived, and it was because of the famous "Eight Kings Rebellion" caused by the division of state power in the early years of the Western Jin Dynasty. This rebellion immediately disintegrated the Western Jin Dynasty, and then Wuhu took the opportunity to move inward, resulting in a "five chaos" situation. Among them, the Tuoba nationality of Xianbei nationality finally established the Northern Wei Dynasty. However, in the Western Jin Dynasty, the royal clan moved south, and Si Marui proclaimed himself emperor in Jiankang, which was called the Eastern Jin Dynasty in history. From then on, it entered the period of great division in the history of China-the Southern and Northern Dynasties.
In the early years of the Northern Wei Dynasty, politics was clear, and the official position and court system were set after the Han system, which made it strong for a while. But it declined during the reign of Xiaowu, and the emperor set up a puppet. He left Chang 'an for Yu Wentai. At the same time, Gao Huan established Ming Di and moved its capital to Yecheng, known as the Eastern Wei Dynasty in history. Later, Gao Huan poisoned Emperor Min, and he became emperor himself, known as Beiqi in history. At the same time, Yu Wentai poisoned Emperor Xiaowu, established the Western Wei Dynasty and took it into his own hands. Yu Wentai seems to be the prototype of Yu in Chu Qiao Biography.
Unlike the love of beauty over mountains and rivers, the Southern Dynasties made great efforts to conquer the land of Xichuan, and then defeated the Northern Qi and unified the North. Lay the foundation for the reunification of the whole country in the Sui Dynasty.
