《贞观政要·卷十·论慎终》
他们对语言的要求是崇尚朴实而弃绝浮华；论人，则重用忠臣良将，鄙视奸佞小人；制度上，杜绝奢侈崇尚俭约；谈物产，重视谷物棉帛，轻视奇珍异宝。
其语道也，必先淳朴而抑浮华；其论人也，必贵忠良而鄙邪佞；言制度也，则绝奢靡而崇俭约；谈物产也，则重谷帛而贱珍奇。
Their requirement of language was to uphold simplicity and reject superficiality; when discussing people, they attached great importance to loyal ministers and generals, and despised treacherous villains; when it came to the system, they rejected extravagance and upheld frugality; when discussing commodities, they attached importance to grains and cotton, and despised rare and strange treasures.
