《汉书·传·儒林传》
主上行为不当，臣不直言纠正来尊崇天子，反而因他有过错而杀了他，代替他面南而立，不是杀害君主是什么？ 
夫主有失行，臣不正言匡过以尊天子，反因过而诛之，代立南面，非杀而何？ 
If the sovereign's conduct is improper, the subject should remonstrate with him to rectify. Killing him, however, because he has committed an offense, and taking his place in facing the south is none other than killing the sovereign, is it not?
