Wu Jing participated in some battles under Sun Jian's banner and was commissioned as a Cavalry Commandant () for his contributions. Sun Jian was killed in action at the Battle of Xiangyang in 191 against Liu Biao's forces. Sometime in the early 190s, Wu Jing was appointed by the warlord Yuan Shu as the Administrator () of Danyang Commandery (丹楊郡; around present-day Xuancheng, Anhui), and was sent to attack and seize the commandery from its previous administrator, Zhou Xin. Wu Jing was at Qu'e County (曲阿縣; in present-day Danyang, Jiangsu) at the time and had not moved to Danyang yet. Sun Jian's eldest son, Sun Ce, brought along his family and followers, including Sun He () and Lü Fan, to join Wu Jing in Qu'e County. Wu Jing combined forces with his nephew to attack the bandits led by Zu Lang () in Jing County and drove the bandits away.
