After Deng Ai was escorted away, Zhong Hui started a rebellion against Wei in Chengdu on 1 March 264, but the rebellion failed when some Wei officers, who were unwilling to participate, mutinied against Zhong Hui and killed him on 3 March 264. After Zhong Hui's death, Deng Ai's subordinates caught up with the convoy escorting their general, freed him, and brought him back to Chengdu. When Wei Guan heard about it, he ordered Tian Xu to lead troops to attack Deng Ai.
