《后汉书·列传·皇甫张段列传》
现在我回督本土，检举劾察诸郡，与亲戚朋友断绝往来，杀辱故旧，大家诽谤我，暗害我，这是理所当然的。
今臣还督本土，纠举诸郡，绝交离亲，戮辱旧故，众谤阴害，固其宜也。
Now that I have returned to supervise my hometown, I have investigated and impeached all the counties, cut off contact with my relatives and friends, killed and humiliated my old friends. Everyone slanders me and secretly harms me, which is understandable.
