In 231, when Zhuge Liang launched his fourth invasion of Wei, Cao Rui ordered Sima Yi and Zhang He to lead Wei forces west to counter the invasion. When Zhang He's army arrived in Lueyang County, Zhuge Liang retreated to Mount Qi (the mountainous regions around present-day Li County, Gansu) to defend his position. When Sima Yi ordered Zhang He to pursue the enemy, Zhang He refused and said that according to classical military doctrine, they should not pursue an enemy force returning to its base. Sima Yi insisted, so Zhang He had no choice but to pursue the retreating Shu forces. He fell into an ambush at Mumen Trail (木門道; near present-day Mumen Village, Mudan Town, Qinzhou District, Tianshui, Gansu) and died after a stray arrow hit him in the right knee. Cao Rui granted him the posthumous title "Marquis Zhuang" (), which literally means "robust marquis".
