《战国策·秦三·谓应侯曰君禽马服乎》
如果现在秦军进攻赵国，北边的土地将归入燕国，东边的土地将归入齐国，南边的土地将归入楚国、魏国，那么秦国所得到的土地就没有多少了。
今攻赵，北地入燕，东地入齐，南地入楚、魏，则秦所得不一几何。
If the Qin army attacks the State of Zhao now, the land in the north will belong to the State of Yan, the land in the east will belong to the State of Qi, and the land in the south will belong to the State of Chu and the State of Wei. Then the land obtained by the State of Qin will not be much.
