《资治通鉴·唐纪·唐纪三十七》
此前，百官请求加封张皇后尊号为 辅圣 ，肃宗因此事问中书舍人李揆，李揆回答说： 自古以来皇后都没有尊号，只有中宗时韦皇后曾经有过尊号，怎么能够效法呢！ 
先是百官请加皇后尊号曰 辅圣 ，上以问中书舍人李揆，对曰： 自古皇后无尊号，惟韦后有之，岂足为法！ 
Before this, the civil and military officials requested to bestow the honorary title of "Fusheng" on Empress Zhang. Emperor Suzong inquired with Li Kui, a member of the Zhongshu, about this matter, and Li Kui replied, "Since ancient times, the empress has had no honorary title. Only Empress Wei during the reign of Emperor Zhongzong has ever had an honorary title. How can this be followed?"
