《北史·列传·卷三十三》
原先，张谠的妻子皇甫氏被北魏军队抢走，朝廷把她赠给太监做奴婢。皇甫氏假装痴呆，才免于替太监梳洗沐浴。
谠妻皇甫氏被掠，赐中官为婢，皇甫遂诈痴，不能梳沐。
Zhang Jin's wife, née Huangfu, had earlier been captured by Northern Wei troops and had been granted by the court to a eunuch as a maidservant. Ms. Huangfu pretended to be mentally ill and thus managed to avoid grooming and bathing the eunuch.
