《汉书·志·五行志上》
董仲舒认为，鲁国伯姬嫁到宋国五年，宋恭公去世，伯姬幽居深宫守节三十多年，还为国家的祸乱忧伤，这样就积阴而生阳，所以发生了火灾。
董仲舒以为伯姬如宋五年，宋恭公卒，伯姬幽居守节三十余年，又忧伤国家之患祸，积阴生阳，故火生灾也。
Dong Zhongshu believed that the daughter of the Duke of Lu, Bo Ji, had been married to the State of Song for five years when Duke Gong of Song died. Bo Ji lived in seclusion in the deep palace and remained chaste for more than thirty years, and still worried about the chaos in the country. This is how the accumulation of yin energy gave birth to yang energy, and so the fire occurred.
