The historical background of Chuqiao Biography is set in the Western Wei Dynasty, from the well-known Three Kingdoms to the Jin Dynasty and then to the Southern and Northern Dynasties. The political situation in the Northern and Southern Dynasties was chaotic, and the North and South confronted each other. Xianbei people unified the north, established the Northern Wei Dynasty, and later split into the Eastern Wei Dynasty (later Luzhen Northern Qi Dynasty) and the Western Wei Dynasty (later Northern Zhou Dynasty). Northern Wei, Eastern Wei, Western Wei, Northern Zhou and Northern Qi are collectively referred to as the Northern Dynasties. The Southern Dynasties were Song, Qi, Liang and Chen in the south.
