At the end of the Jin Dynasty, the Eight Kings were in chaos, and the Central Plains was in chaos.
The Hu people who moved inland took advantage of the situation to compete, and the Xiongnu, Xianbei, Jie, Di, and Qiang tribes established their own kingdoms one after another, called the Sixteen Kingdoms. The Yongjia beacon burned away the prosperity of Luoshui, Chang'an fell, and the Western Jin Dynasty was wiped out. Yiguan crossed south, and the Jin Dynasty settled on the left side of the river. Since then, the northern land has been torn apart. Governments have been changing endlessly, and conquests have been going on for years. The people are in dire straits.
Later generations of boys raised their arms and waved their arms in the wilderness: How could the land of Han be allowed to be filled with barbarians, and how could Chinese people dare to cross in a hurry?
Until the Qin Dynasty was unified, Feishui was defeated and the world was in chaos. The Tuoba clan of Xianbei established the Wei Dynasty, worked hard to govern, and finally wiped out the northern separatist regime. Northern Liang surrendered, and the troubled times were finally settled. The confrontation between the Southern and Northern Dynasties began from this point on.
