After the initial victory, Zhang Yi accurately realized the supply problems Shu faced, and suggested withdrawal to Jiang Wei. Jiang Wei, wanting to ride the momentum of his victory to take Didao, angrily turned down the suggestion and besieged Didao. As news of Wang Jing venturing out to engage Jiang Wei reached Chen Tai, he immediately and accurately predicted that Wei would suffer a defeat and thus ordered his cavalry to the rescue, and he would lead the infantry himself to follow. Chen Tai also wrote an urgent message to the Wei imperial court for additional reinforcements. When the news of disaster reached the Wei capital, Luoyang, the imperial court was worried that Chen Tai alone would not be able to salvage the situation. Changshui Colonel Deng Ai, who had just arrived in Luoyang, was appointed Acting General Who Stabilizes the West, and was sent to assist Chen Tai. As soon as Deng Ai left Luoyang, Wei regent Sima Zhao also put his uncle, Grand Commandant Sima Fu, in charge of Guanzhong to help coordinate logistics for the war effort.
