《资治通鉴·唐纪·唐纪十》
魏徵劝谏道： 陛下因为储备的事就将官吏降职，我担心此风气盛行，则会造成民不聊生，这并非陛下巡幸各地的本意。
魏征谏曰： 陛下以储偫谴官吏，臣恐承风相扇，异日民不聊生，殆非行幸之本意也。
Wei Zheng advised: "Your Majesty demoted officials because of the reserve issue. I worry that if this practice becomes prevalent, it will cause people's livelihood to be unbearable, which is not what Your Majesty intended when you visited various places."
