the city and personally welcomed him back. Zhang Liao was reassigned to serve as General Who Defeats Bandits (盪寇將軍). In around 206, Cao Cao sent Zhang Liao to counter the unrest in some counties in Jiangxia Commandery (present-day eastern Hubei). Zhang Liao achieved success and returned to his garrison at Linying (臨潁; present-day Linying County, Henan). He was promoted from a Secondary Marquis to a Marquis of a Chief Village (都亭侯). In 207, Zhang Liao followed Cao Cao on a campaign against Yuan Shang, who had allied with the Wuhuan tribes in northern China. When Cao Cao was preparing to attack the enemy in Liucheng (柳城; present-day Xingcheng, Liaoning), Zhang Liao warned him that Jing Province's Governor Liu Biao take advantage of his absence from Xu to send Liu Bei to attack Xu and take control of the capital. However, Cao Cao felt that Liu Biao would not send Liu Bei to attack Xu because he did not trust Liu Bei, so he proceeded with the campaign against Yuan Shang and the Wuhuan. When they encountered the enemy, Zhang Liao displayed great fervour and strongly urged Cao Cao to launch an attack. Cao Cao was so impressed with Zhang Liao that he passed him his personal signal flag. Zhang Liao led the assault on the Wuhuan at White Wolf Mountain (白狼山; near present-day Lingyuan, Liaoning), defeated them and executed the Wuhuan chieftain Tadun.

During the mobilisation, some soldiers started a mutiny and set fire to the camp at night and caused panic. Zhang Liao told his subordinates: "Don't make any move yet. There isn't a single company whose members are all involved in the mutiny, so the mutineers must be trying to cause chaos and make everyone else join them." He ordered all the soldiers who were not involved in the mutiny to remain in their positions and sit down, and then led his personal guards to the main command post to restore order. The leaders of the mutiny were identified and executed. During the Battle of Red Cliffs, Zhang Liao were stationed in Changsha In 209, after the Battle of Red Cliffs, Chen Lan (陳蘭) and Mei Cheng (梅成) started a rebellion in Lu County (六縣;
