At the end of the Eastern Han Dynasty, the princes were separatist, attacking and annexing each other, the court was politically corrupt, and foreign relatives and eunuchs were interfering in politics, making the country unstable. Xun Yu stood out in troubled times and was called "the talented king". Xun Yu had made little achievements in his youth, and was recommended by famous scholars. In the first year of Yonghan (189), he was promoted as Xiaolian and appointed as the palace guard (in charge of the emperor's pens, ink, paper and other items). From then on, this descendant of Xunzi officially stepped onto the stage of history, assisted Cao Cao, conspired with the great cause, started his magnificent ambitions, and became a famous politician and strategist at that time.
