《国语·周语·内史过论神》
内史过答道： 过去昭王娶了房的女子，称为房后，德行有缺，与丹朱相好，丹朱附身与她相配而生了穆王。
对曰： 昔昭王娶于房，曰房后，实有爽德，协于丹朱，丹朱凭身以仪之，生穆王焉。
The Minister of the Interior, Guo, replied: In the past, King Zhao married a woman of the Fang people, known as the Fang Queen. She was of poor moral character and had an affair with Danzhu, who possessed her and had sexual intercourse with her, giving birth to King Mu.
