《宋史·列传·卷二百三十六》
赵范、赵葵夜晚商量明天早晨进攻的方向，赵葵说： 东面的方向有利，不如出兵城东门。 赵范说 ：我军从城西门出曾经失利，叛军一定认为这个方向容易取胜，我军就借着他们认为容易取胜的方向去攻击他们，一定能成功。
范、葵夜议诰朝所向，葵曰： 东向利，不如出东门。 范曰： 西出尝不利，贼必见易，因其所易而图之，必胜。
Zhao Fan and Zhao Kui discussed the direction of the attack the next morning. Zhao Kui said: "The east is favorable, so let's send troops to the east gate." Zhao Fan said: "Our army has failed in the past when we went out from the west gate. The rebels must think this direction is easy to win. Our army will attack them with the direction they think is easy to win."
