Dong Xi 董禧

In Chapter 92 of the Romance, Han De, the great general of Xiliang who has become Xiahou Mao's vanguard, loses all four of his sons at Zhao Yun's hands at Mount Fengming, and then, in the battle in which Xiahou Mao leads out his troops in person, charges at Zhao Yun vowing revenge and is himself killed by Zhao Yun's spear. Having fallen back more than 10 li, Xiahou Mao confers with his generals through the night, saying that Zhao Yun still has a hero's spirit even in old age and that only now does he believe the story of Changban at Dangyang, and asks what is to be done when no one can match him. Romance, Ch. 92 §4–8 · 12–14

Cheng Wu, the Army Adviser and son of Cheng Yu, says that Zhao Yun has courage but no strategy, and that if two bodies of troops are set in ambush on either side, and the Area Commander first falls back to lure Zhao Yun to where the ambush lies, then climbs a hill and directs the troops on all sides to surround him layer upon layer, Zhao Yun can be captured. Xiahou Mao follows his advice and has Dong Xi lie in ambush on the left with 30,000 troops and Xue Ze on the right with 30,000 troops. Romance, Ch. 92 §14–15

The next day, when Xiahou Mao advances again, Deng Zhi tells Zhao Yun that there must be a trick behind the return of the Wei army that fled in great defeat the night before, and urges him to be on guard. Zhao Yun says that such a milk-smelling child is not worth talking about and spurs his horse out; when the Wei general Pan Sui flees before three bouts are over, and the eight generals let Xiahou Mao go first and then flee one after another, he pursues them deep into enemy ground. As Deng Zhi hastily gathers his troops and pulls back, Dong Xi from the left and Xue Ze from the right drive their troops in by two roads, and Deng Zhi, with few troops, cannot rescue Zhao Yun. Romance, Ch. 92 §15–17

Trapped in the middle of the encirclement, Zhao Yun charges east and strikes west with some thousand troops, but Xiahou Mao on the hill points to wherever Zhao Yun goes and directs the three armies, so he cannot break out. Having fought from the hour of chen to the hour of you and waiting for the moon to rise, Zhao Yun, as arrows and stones pour down from all sides, looks up to heaven and sighs, 'I would not admit that I was old, and now I am to die here.' Romance, Ch. 92 §17–19

Just then Zhang Bao charges in with a man's head hanging below his horse's neck and says he has killed the Wei general Xue Ze, who was blocking the way, and then Guan Xing, wielding the Green Dragon Crescent Blade, rides in with a man's head in his hand. Guan Xing says that he has come to help with 5,000 troops on the Chancellor's orders, and that he has just met the Wei general Dong Xi on the battlefield, cut him down with a single stroke of his blade and brought his head here hanging at his side. That night the troops of the three roads attack together and crush the Wei army, and Xiahou Mao flees to Nan'an Commandery. Romance, Ch. 92 §19–23
