《资治通鉴·后唐纪·后唐纪四》
天皇王的性情谨慎孝顺，他的母亲得病后不能吃饮，他也不吃饮，天天侍奉在母亲的身边，应对母亲有时不符合她的意思，母亲睁大眼睛看他时，就害怕得快步避开，不再叫他回来他就不敢再进来见太后。
天皇王性孝谨，母病不食亦不食，侍于母前应对或不称旨，母扬眉视之，辄惧而趋避，非复召不敢见也。
Emperor Tianwang was a cautious and filial man. When his mother became ill and was unable to eat or drink, neither would he. Every day he waited on his mother. Should his words or actions displease her and should she open her eyes and glare at him, he would be terrified and quickly retreat. He would not return unless called.
