臧霸
In 209, after the Battle of Red Cliffs, Chen Lan () and Mei Cheng () started a rebellion in Lu County (六縣; present-day Lu'an, Anhui). Cao Cao sent two separate forces to suppress the rebellion: Yu Jin and Zang Ba to attack Mei Cheng; Zhang Liao, with Zhang He and Niu Gai () as his deputies, to attack Chen Lan. Mei Cheng and his followers, who numbered about 3,000, surrendered when Yu Jin and Zang Ba showed up.
