《宋史·列传·卷七十三》
范仲淹说 ：太后，是皇帝母亲的称号，自古以来没有因为保护抚育皇帝有功而代替皇帝立太后的。
仲淹曰： 太后，母号也，自古无因保育而代立者。
Fan Zhongyan said: Empress dowager is the title for the emperor's mother. Since ancient times, there has never been anyone who took the place of the emperor to establish an empress dowager on account of their meritorious service in caring for and bringing up the emperor.
