In the spring of 241, Sun Quan prepared to launch a campaign against Wei. Yin Zha (殷札), the administrator of Wu Commandery, advised Sun Quan to attack Wei in coordination with their ally state, Shu Han. According to Yin Zha's suggested plan, the Shu forces would attack Wei from the west of Chang'an, while the Wu forces would attack Wei from three directions: Zhuge Jin and Zhu Ran to attack Xiangyang; Lu Xun and Zhu Huan to attack Shouchun (壽春; present-day Shou County, Anhui); Sun Quan to attack the Huai River region and enter Xu Province. Yin Zha explained that this coordinated campaign would wear down Wei's defences because they were unable to fend off attacks on two fronts. However, Sun Quan did not follow his plan.
