《明史·列传·卷一百零一》
慈圣太后将要返回慈宁宫，告诉居正 ：我不能朝夕看着皇帝，担心他不像从前那样求学、勤于政务，有负先帝的嘱托。
慈圣太后将还慈宁宫，谕居正谓： 我不能视皇帝朝夕，恐不若前者之向学、勤政，有累先帝付托。
Empress Dowager Ci Sheng was going to return to Ci Ning Palace and told Ju Zheng: I can't see the emperor day and night, worrying that he is not as good as before in learning and working hard in political affairs, failing the entrustment of the late emperor.
