When Jiang Wei received news that another Wei army led by Zhong Hui had occupied Hanzhong Commandery, he led his troops from Tazhong back further into Shu territory, but was pursued by Yang Xin to Qiangchuankou (彊川口; the intersection of the Bailong and Jialing rivers), where he was defeated. Jiang Wei learnt that Zhuge Xu had blocked his retreat route at the bridge of Yinping, so he led his men through Konghan Valley (孔函谷; south of present-day Xigu District, Lanzhou, Gansu) to the northern road in an attempt to bypass Zhuge Xu's position. When Zhuge Xu heard about it, he retreated back by 30 "li". By then, Jiang Wei and his troops had travelled about 30 "li" on the northern road when they heard that Zhuge Xu had lifted the blockade at the bridge. Jiang Wei ordered his troops to quickly turn back and cross the bridge. Zhuge Xu tried to turn back to block Jiang Wei again but arrived at the bridge one day too late. After crossing the bridge, Jiang Wei moved to the mountain pass of Jiange and garrisoned there. Zhong Hui attacked Jiang Wei at Jiange several times but was unable to breach the defences.
