《战国策·燕二·秦召燕王》
用占领胶东的事谴责燕国，用占领济西的事谴责赵国，用占领叶、蔡两地的事谴责魏国，用阻断黾塞的事谴责楚国，用占领宋地的事谴责齐国，这样一定会使秦王的话像反复循环一样，无休无止。
适燕者曰： 以胶东。 适赵者曰： 以济西。 适魏者曰： 以叶、蔡。 适楚者曰： 以塞鄳隘。 适齐者曰： 以宋。 
By accusing the state of Yan of occupying Jiaodong, the state of Zhao of occupying Jixi, the state of Wei of occupying Ye and Cai, the state of Chu of blockading Minchi, and the state of Qi of occupying Song, he would have made his words go around and around, endlessly.
