晏子使楚。楚人以晏子短，楚人为小门于大门之侧而延晏子。晏子不入，曰：“使狗国者从狗门入。今臣使楚，不当从此门入。”傧者更道，从大门入。见楚王，王曰：“齐无人耶？使子为使。”晏子对曰：“齐之临淄三百闾，张袂成阴，挥汗成雨，比肩继踵而在，何为无人？”王曰：“然则何为使子？”晏子对曰：“齐命使，各有所主。其贤者使使贤主，不肖者使使不肖主。婴最不肖，故宜使楚矣。”
晏子将使楚。楚王闻之，谓左右曰：“晏（yàn）婴，齐之习辞者也。今方来，吾欲辱之，何以也？”左右对曰：“为其来也，臣请缚（fù）一人，过王而行，王曰：‘何为者也？’对曰：‘齐人也。’王曰：‘何坐？’曰：‘坐盗。’晏子至，楚王赐晏子酒，酒酣，吏二缚一人诣(yì)王。王曰：“缚者曷(hé)为者也？”对曰：“齐人也，坐盗。”王视晏子曰：“齐人固善盗乎？”晏子避席对曰：“婴闻之，橘生淮南则为橘，生于淮北则为枳，叶徒相似，其实味不同。所以然者何？水土异也。今民生长于齐不盗，入楚则盗，得无楚之水土使民善盗耶？”王笑曰：“ 圣人非所与熙也，寡人反取病焉。”
