《资治通鉴·汉纪·汉纪三十六》
如今，我看到正在大修北宫，农民不能适时耕作。自古以来，忧患之事不是宫室狭小，只是担心人民不安。应当暂且停止修建北宫，以顺应天心。 
窃见北宫大作，民失农时；自古非苦宫室小狭，但患民不安宁，宜且罢止，以应天心。 
Today, I see that the North Palace is being renovated, and the farmers cannot cultivate in time. Since ancient times, the cause of anxiety has not been the smallness of the palace, but the worry about the people's anxiety. We should temporarily stop building the North Palace, so as to follow the will of Heaven.
