 When Zhong Hui and Zhuge Xu arrived near Jiange, Zhong Hui desired to seize control of Zhuge Xu's command, so he secretly reported to the Wei imperial court that Zhuge Xu displayed cowardice in battle.As a result, Zhuge Xu was stripped of his command and sent back to the Wei capital Luoyang, while Zhong Hui took command of his army.Zhong Hui then ordered an attack on Jiange but failed to conquer the mountain pass because the Shu forces put up a strong defence, so he retreated.
