《资治通鉴·汉纪·汉纪二十一》
 我又曾经听说，家庭如果安详和睦，天下自然治理得好。所以《诗经》开头就是《国风》。《礼记》开头就讲冠礼、婚礼。
 臣又闻室家之道修，则天下之理得，故《诗》始《国风》，《礼》本冠、婚。
I have also heard that if the family is peaceful and harmonious, the country will naturally be well-governed. Therefore, the "Book of Songs" begins with the "Folk Songs". The "Book of Rites" begins with "Capping Ceremony" and "Wedding Ceremony".
