Li Dian
After Li Zheng's death, Li Dian was appointed as the Prefect () of Yingyin County (潁陰縣; in present-day Xuchang, Henan) and General of the Household (), and took over command of his cousin's troops. Li Dian was known to be very studious since he was a youth, and he showed little interest in military affairs. He read classics such as the "Spring and Autumn Annals" and the "Zuo Zhuan". Cao Cao was pleased with Li Dian and wanted to test his abilities. He reassigned Li Dian to be the Administrator () of Lihu Commandery (離狐郡; southeast of present-day Dongming, Shandong), where Li was primarily in charge of managing civil affairs.
