《资治通鉴·齐纪·齐纪六》
拓跋英对部下说： 他们的主帅出身低贱，不能统一协调作战，我如果挑选精兵集中力量攻打他们的一个营垒，其他的一定不会来援救。如果攻克一个营垒，其余四个就都会不战而逃。 
英曰： 彼帅贱，莫相统壹。我选精卒并攻一营，彼必不相救；若克一营，四营皆走矣。 
Tuoba Ying said to his subordinates: "Their chief commander comes from a humble background and can't coordinate作战their operations. If I select our best troops and concentrate on attacking one of their camps, the others will definitely not come to its rescue. If we conquer one camp, the others will all flee without a fight."
