廖化
Guo Huai stood by his initial plan and said: "If we attack Liao Hua, we can catch the enemy off guard. Jiang Wei will then definitely turn back to save Liao Hua. By the time he returns, we would have already defeated Liao Hua. By doing so, we can make Jiang Wei and his men weary from travelling forth and back. If Jiang Wei does not meet the barbarians, the barbarians will retreat on their own. This is the best approach." He then instructed Xiahou Ba to lead one detachment to pursue Jiang Wei towards Tazhong (沓中; northwest of present-day Zhugqu County, Gansu), while he led the other group to attack Liao Hua. As Guo Huai foresaw, Jiang Wei did turn back to save Liao Hua and failed to meet up with Zhiwudai.
