The disputes between noble families and poor families, between noble families and imperial power, and between barbarians and Han people have led to different changes in the world. Ten years ago, the conflict between the noble clans and the poor families intensified, and the Chu Kingdom was divided into two. Huang Zheng, a general of the common people, established the Northern Yan Dynasty, fought against the Hu people in the north and the gentry in the south. The aristocratic families, mainly the Wang family of Langya and the Xie family of Chenjun, moved south to help the Han family's descendants rebuild the Chu state, which became known as Southern Chu. The two countries lived in peace for ten years. Ten years later, Jixia Academy opened, and a storm arose again.
