Cao Cao was very pleased to see Jia Xu. He held Jia Xu's hand and said: "You are the person who helps to make my trustworthiness known throughout the Empire." Jia Xu was appointed Bearer of the Mace (執金吾) and enfeoffed as a Marquis of a Chief Village (都亭侯). He was later promoted to the position of Governor (牧) of Ji Province. As Ji Province was still under Yuan Shao's control then, Jia Xu served as a military adviser to Cao Cao, who then held the appointment of Minister of Works (司空).
