According to legend, Cao Xiu did not believe Zhou Fang at first. Zhou Fang cut off locks of his hair to prove his "loyalty". In any case, Zhou Fang knew the terrain well, so he started to lead Cao Xiu into a clearing, where Cao Xiu could set up camp. However, before they left, Jia Kui advised Cao Xiu not to trust Zhou Fang. Cao Xiu not only did not heed Jia Kui's words, but went ahead and fell for Zhou Fang's ruse. He also removed Jia Kui from command and moved on with his 70,000 troops.
