邹忌讽齐王纳谏

       邹忌修八尺有余，而形貌昳丽。朝服衣冠，窥镜，谓其妻曰：“我孰与城北徐公美？”其妻曰：“君美甚，徐公何能及君也？”城北徐公，齐国之美丽者也。忌不自信，而复问其妾曰：“吾孰与徐公美？”妾曰：“徐公何能及君也？”旦曰，客从外来，与坐谈，问之客曰：“吾与徐公孰美？”客曰：“徐公不若君之美也。”明日徐公来，孰视之，自以为不如；窥镜而自视，又弗如远甚。暮寝而思之，曰：“吾妻之美我者，私我也；妾之美我者，畏我也；客之美我者，欲有求于我也。”

       于是入朝见威王，曰：“臣诚知不如徐公美。臣之妻私臣，臣之妾畏臣；臣之客欲有求于臣，皆以美于徐公。今齐地方千里，百二十城，宫妇左右莫不私王，朝廷之臣莫不畏王，四境之内莫不求于王：由此观之，王之蔽甚矣。”

       王曰：“善。”乃下令：“群臣吏民能面刺寡人之过者，受上赏；上书谏寡人者，受中赏；能谤讥于市朝，闻寡人之耳者，受下赏。”令初下，群臣进谏，门庭若市；数月之后，时时而间进；期年之后，虽欲言，无可进者。

       燕、赵、韩、魏闻之，皆朝于齐。此所谓战胜于朝廷。
