The founding name is "Jin", which is called the Western Jin Dynasty in history. In 280 AD, the Western Jin Dynasty destroyed Soochow and unified China, thus ending the Three Kingdoms period and entering the Jin Dynasty.

The Three Kingdoms (220-280) is a historical period connecting the Eastern Han Dynasty and the Western Jin Dynasty, which is divided into three regimes: Cao Wei, Shu Han and Dongwu. Battle of Red Cliffs and Cao Cao were defeated by Sun Liu's allied forces, which laid the rudiment of the tripartite confrontation among the three countries.

The Jin Dynasty (266-420) was divided into two periods: the Western Jin Dynasty and the Eastern Jin Dynasty, in which the Western Jin Dynasty was one of the unified dynasties in China history and the Eastern Jin Dynasty was one of the six dynasties. In the Jin Dynasty 155, there were 15 emperors.

In 266, he usurped Wei, established Luoyang as its capital, and gained the title of Gold. Historically known as the Western Jin Dynasty, Wu was destroyed in 280 and unified. After the Eight Kings Rebellion and Yongjia Disaster, the national situation gradually declined. In 3 16, the western Jin dynasty was destroyed by barbarians in the north, and there was chaos in the north, which was called five chaos in history. In 3 17, Jinshi moved south, and Si Marui established the Eastern Jin Dynasty under Jianye, which made many northern expeditions.

In 383, the Eastern Jin Dynasty was temporarily consolidated after the war with the former Qin Dynasty. During the Jin Dynasty, Wuhu moved to the Central Plains, strengthened ethnic integration, and northerners moved south to develop the Jiangnan area. In 420, Liu Yu established Liu Song, and the Eastern Jin Dynasty perished. The history of China entered the Southern and Northern Dynasties.
