《后汉书·列传·李陈庞陈桥列传》
臣还希望在陛下之世，当蒙安全，而又因谗佞之人伤毁忠正之士，这是天地之大禁，人主之至诚。
臣犹冀在陛下之世，当蒙安全，而复以谗佞伤毁忠正，此天地之大禁，人主之至诫。
I hope that your majesty’s reign will be peaceful and secure. However, due to the slandering and undermining of loyal and righteous officials by treacherous and flattering people, it is the great taboo of Heaven and Earth, and the utmost sincerity of the emperor.
