On the origin of the Qin people in Taohuayuan, Bi Tao, a poet in the Song Dynasty, said

Bi Tao's point of view is that the Qin people in the account were left over after Sima Cuo defeated Longxi soldiers in 280 BC. According to relevant records, Bi Tao, a poet in the Song Dynasty, wrote a seven-character poem called Sima CuO City, which described that the Great Wall of the North was trapped by the enemy and came to work for Wu Lingren. I suspect that the man who planted peaches in the cave was the plate maker at that time.
