《资治通鉴·后梁纪·后梁纪五》
大王应该按兵不动，我请求用骑兵先去骚扰一下，使他们得不到休息，到晚上营垒还没有修好，柴火锅灶还没准备齐全，乘他们疲乏的时候，可以一举消灭。 
王宜按兵勿战，德威请以骑兵扰之，使彼不得休息，至暮营垒未立，樵爨未具，乘其疲乏，可一举灭也。 
Your Majesty should stay put, I ask to harass them with cavalry first, so that they will not get rest, and by the evening when the camp is not yet built, and the firewood and kitchen are not ready, they can be wiped out when they are exhausted.
