《宋史·列传·卷一百三十二》
应该先派亲近的前去经营准备，等到防御设置完备，再回去不晚。 当时朝廷计议已经决定，没有听从，不久就后悔了。
绍兴二年，金人忽遣宇文虚中来，言和议可成，当遣一人诣元帅府受书还，虚中欲弁与正使王伦探策决去留，弁曰： 吾来，固自分必死，岂应今日觊幸先归。愿正使受书归报天子，成两国之好，蚤申四海之养于两宫，则吾虽暴骨外国，犹生之年也。 伦将归，弁请曰： 古之使者有节以为信，今无节有印，印亦信也。愿留印，使弁得抱以死，死不腐矣。 伦解以授弁，弁受而怀之，卧起与俱。金人迫弁仕刘豫，且訹之曰： 此南归之渐。 弁曰： 豫乃国贼，吾尝恨不食其肉，又忍北面臣之，吾有死耳。 金人怒，绝其饩遗以困之。
"You should send someone close to you to make arrangements in advance, and it will not be too late to go back when the defenses are complete." At that time, the imperial court had already decided on a plan and did not listen to him, and soon regretted it.
