He Qi
As He Qi gained greater fame from his successful subjugation of restless local tribes in the Jiangdong region, he started participating in some battles against Sun Quan's rival, Cao Cao, the warlord who controlled the central government of the Eastern Han dynasty in its final years. In 215, He Qi fought in the Battle of Xiaoyao Ford when Sun Quan led his forces to attack the heavily fortified Hefei, which was defended by Cao Cao's general Zhang Liao and others. Sun Quan's forces suffered a devastating defeat at the hands of Zhang Liao and his colleagues in the battle and barely managed to retreat alive. During the battle, one of Sun Quan's officers, Xu Sheng, apparently lost his long spear in the midst of the fighting. He Qi found Xu Sheng's spear by coincidence and returned it to him.
