A Different Fifth Century AD

What should we do with the primitive tribes who accidentally traveled to the north of Northeast China? How does a Han Chinese break out from ethnic minorities such as the Northern Wei, Xianbei, Rouran, Fuyu, Khitan, and Gaoche? How can we compete with powerful men such as Tuoba Gui of the Northern Wei Dynasty, Yao Xing of the Later Qin Dynasty, Liu Yu of the Eastern Jin Dynasty, Helian Bobo of Hu Xia, Yujiulu Shelun of Rouran, Murong De and Murong Sheng of the Later Yan Dynasty of the Southern Yan Dynasty? What are the stories of Kumarajiva, Xie Daoyun, Hua Mulan, etc.? End the era of "Five Husbands Chaosing China" ahead of schedule, save the Han people, save the weak and small nations, and realize the coming of all nations to Korea!
