《资治通鉴·魏纪·魏纪一》
如果这一带为平原旷野，我们还要担心有互相追逐的困扰；如今他们沿着山岭布署军队，不但兵力无法展开，反而因困在树木乱石之中，自己的渐渐精疲力竭，我们要有耐心，等待他们自己败坏而加以攻击。 
若此间是平原旷野，当恐有颠沛交逐之忧；今缘山行军，势不得展，自当罢于木石之间，徐制其敝耳。 
If this terrain were a flat wilderness, we would still be concerned about the threat of pursuit. Now that they have deployed their army along the mountain ridge, not only will they be unable to deploy their troops, but they will also gradually exhaust themselves by being trapped among the trees and rocks. We must be patient, wait for them to become exhausted, and then attack.
