《汉书·传·匡张孔马传》
有时他上书言事，已经写好的奏章总是删削修改，认为上书张扬皇上的过失，以此来求得忠直的美名，是做官的大罪。
时有所言，辄削草稿，以为章主之过，以奸忠直，人臣大罪也。
Sometimes he made written statements, the memorials that had been written were always revised, he believed that it was a serious crime for an official to flatter the emperor by emphasizing the emperor's faults in the memorials in order to gain reputation for loyalty.
