《金史·列传·卷四十三》
但是女子无论美丑，入宫以后容易产生嫉妒之心，陛下如果想要多子女，不能不知道这种情形并事先加以告诫。 
然女无美恶，入宫见妒，陛下欲广嗣续，不可不知而告戒之。 
However, regardless of whether a woman is beautiful or not, after she enters the palace, jealousy is easily produced so if Your Majesty wishes to have more children, you cannot ignore this situation and must warn them in advance.
