曹操
The duel between Ma Chao and Xu Chu is not documented in the "Sanguozhi" and is likely to be fictional. Ma Chao, Cao Cao and Xu Chu's biographies gave an account of a meeting between Cao Cao, Ma Chao and Han Sui during the battle. Cao Cao rode forth on horseback to speak with Ma Chao and Han Sui. Cao Cao was accompanied only by Xu Chu. Ma Chao had confidence in himself and secretly harboured the intention of charging forward and capturing Cao Cao when they met. However, he had heard of Xu Chu before and suspected that the man with Cao Cao was Xu Chu. He then asked Cao Cao: "Where is your Tiger Marquis?" Cao Cao pointed at Xu Chu, and Xu glared at Ma Chao. Ma Chao was afraid and did not dare to make his move.
