《新五代史·列传·汉臣传第十八》
皇太后于是召尼姑诵读佛书求福消灾，一个尼姑去厕所，回来后，悲号典泣几天不省人事，等到苏醒后讯问她，也不知道是怎么回事。
皇太后乃召尼诵佛书以禳之，一尼如厕，既还，悲泣不知人者数日，及醒讯之，莫知其然。
The Empress Dowager then summoned nuns to read Buddhist scriptures and pray for blessings and to avert disasters. One of the nuns went to the toilet and when she returned, she wept bitterly for days and became unconscious. After she regained consciousness and was questioned, she did not know what had happened.
