Zang Ba
In 198, when the warlords Cao Cao and Lü Bu were at war, Zang Ba and his followers led their troops to help Lü Bu. After Lü Bu's defeat and death at the Battle of Xiapi later that year, Zang Ba and his followers willingly surrendered to Cao Cao and became his subordinates. Cao Cao appointed them to various positions and put Zang Ba in charge of parts of Qing and Xu provinces. Yin Li served as the Administrator of Dongguan Commandery (東莞郡; around present-day Yishui County, Shandong).
