《资治通鉴·后晋纪·后晋纪三》
由于李从益还年幼，后晋高祖的李皇后是后唐明宗曹皇后的女儿，便把许王留养在宫中，又对明宗次妃王淑妃侍奉如同母亲。
从益尚幼，李后养从益于宫中，奉王淑妃如事母。
Because Li Congyi was still young, Empress Li of the Later Jin was the daughter of Empress Cao of the Later Tang, so the Prince of Xu was fostered in the palace. Empress Li honored Wang Shufei, the second concubine of Emperor Ming of the Later Tang, as his mother.
