In 206, Chang Xi () started a rebellion, so Cao Cao sent Yu Jin to lead an army to suppress the revolt. Yu Jin was unsuccessful, so Cao Cao ordered Xiahou Yuan to join Yu Jin in a second expedition against Chang Xi. They defeated the rebels this time and captured over 10 enemy garrisons while Chang Xi surrendered to Yu Jin. Xiahou Yuan was appointed Colonel Who Arranges the Army () after his success. Xiahou Yuan was known for the swift movements of his units in battle, and he often took his enemies by surprise. There was a saying in Cao Cao's army to describe this: "Xiahou Yuan, the Colonel Who Arranges the Army, travels 500 "li" in three days and 1,000 "li" in six days."
