Yan Xing, courtesy nameYanming (彥明), later renamed to Yan Yan (閻艷), was a military general who lived in the late Eastern Han Dynasty. He was a son-in-law of the warlord Han Sui. During the battle against rival warlord Ma Teng, Yan became well known for his skill by cornering Ma Chao. Yan later persuaded Han Sui to join the warlord Cao Cao, but Han had already allied himself with Ma Chao, so he drove Yan away. Yan then personally went to join Cao.
