《资治通鉴·汉纪·汉纪二十》
皇上问给事中匡衡，询问地震日食等天地变化的缘故，衡匡上书说： 陛下亲自身体力行，为国家开辟太平道路，怜悯愚昧的官吏人民，误触法网，连年都有大赦，使老百姓得到改过自新的机会，这是国家之福！
上问给事中匡衡以地震日食之变，衡上疏曰： 陛下躬圣德，开太平之路，闵愚吏民触法抵禁，比年大赦，使百姓得改行自新，天下幸甚！
Your Majesty asked the Monitoring Officer, Kuang Heng, to inquire about the reason for the changes of the natural phenomenon such as earthquake and eclipse. Kuang Heng submitted a letter which said: Your Majesty personally engages in physical labor, and pave the roads to peace for the nation; You show mercy to the ignorant officials and people, those who violate the law, and pardon them every year, so that the people have the opportunities to turn over new leaves. This is the blessing of the nation!
