Zang Ba
When Lü Bu gained control of Xu Province, Zang Ba and his gangs became known as the Taishan Bandits and attacked Lü Bu's ally, Xiao Jian (), and seized the treasury of Langye Commandery. Enraged, Lü Bu personally led his troops to attack Zang Ba, despite opposition from his subordinate Gao Shun, but was driven back. On the other hand, Zang Ba, fearing the bigger threat from the southern warlord Yuan Shu, agreed to make peace with Lü Bu and ally with him against Yuan Shu.
