In March 264, the Wei general Zhong Hui, who took charge of Chengdu following Liu Shan's surrender, started a rebellion against the Wei regent Sima Zhao. However, the rebellion failed and Zhong Hui was killed by his officers who refused to join him. Upon learning of Zhong Hui's death, the Wu emperor Sun Xiu thought that no one was in charge of Shu, so he sent his troops to seize control of the Shu territories. However, the Wu forces led by Bu Xie encountered strong resistance from Luo Xian and his men at Badong Commandery and could not advance further west into the heartland of Shu.
