《战国策·燕二·苏代为奉阳君说燕于赵》
我虽然这样安排了，又担心牵累燕国。奉阳君对朱说： 苏代因为燕王用我而生气，若不任苏代力相，又不任苏代为卿，则差不多要失去燕国了。 
臣虽为之累燕，奉阳君告朱讙曰： 苏子怒于燕王之不以吾故，弗予相，又不予卿也，殆无燕矣。 
 Though I have made such an arrangement, I also worry that Yan State will be implicated. Lord Fengyang said to Zhu, Su Dai is angry because the king of Yan uses me. If you do not let Su Dai use his power to help, and do not appoint him as a minister, then you will almost lose Yan State.
