Yong Province. Zhuge Liang, the Imperial Chancellor of Shu, led the campaign and deployed his troops at Mount Qi (祁山; the mountainous areas around present-day Li County, Gansu). He then sent Ma Su to lead the Shu vanguard to attack Jieting (街亭; in present-day Qin'an County, Gansu) and Gao Xiang to lead another force to station at Liucheng (柳城; in present-day Zhangjiachuan, Gansu) as backup for Ma Su. In response to this invasion, Zhang He led an army to attack Ma Su at the Battle of Jieting and inflicted a devastating defeat on the enemy. At the same time, Guo Huai also led a force to attack Gao Xiang's camp at Liucheng and succeeded in destroying it. Guo Huai then followed up by attacking Tangti (), a rebellious Qiang tribal chief from Longxi Commandery (around present-day Longxi County, Gansu), and defeated him at Fuhan County (枹罕縣; southwest of present-day Linxia County, Gansu). The Wei government granted him the additional appointment of General Who Establishes Might () to honour him for his achievements. Battle of Jianwei In the spring of 229, when Shu forces led by Chen Shi attacked Wudu (武都; around present-day Cheng County, Gansu) and Yinping (陰平; present-day Wen County, Gansu) commanderies, Guo Huai led Wei forces to resist them. However, he retreated after Zhuge Liang led a Shu army to Jianwei (建威; in present-day Longnan, Gansu) as backup for Chen Shi. The Shu forces then conquered Wudu and Yinping commanderies.

Guo Huai turned to the local Qiang and Di tribes for aid and managed to convince them to donate food supplies to the Wei army. He then allocated them accordingly such that all units had sufficient food supplies. The Wei government reassigned him from his position as General Who Establishes Might () to General Who Spreads Martial Might (). Battle of Wuzhang Plains In 234, Guo Huai joined Sima Yi in leading Wei forces to resist another Shu invasion led by Zhuge Liang. When Sima Yi and his troops were stationed at the south of the Wei River, Guo Huai urged them to move to the plains on the
