Hao Meng (died 196 AD) was a military officer serving under the warlord Lü Bu in the late Eastern Han dynasty of China.
Lü Bu was not aware of the identities of the rebels, but he heard their voices and recognised from their accents that they were from Henei.
Gao Shun then led his troops to Lü Bu's office and drove the rebels away by firing arrows at them.
[1] Hao Meng's subordinate Cao Xing refused to betray Lü Bu, so he turned against his superior and fought with him.
By then, Gao Shun had shown up to attack Hao Meng's camp and he beheaded the traitor.
