《礼记·昏义》
教成以后，要举行教成之祭，这是向祖先察告，婚前教育已经完成。祭时用鱼作姐实，用薪、藻这两种水草作羹菜，这些祭品都属于阴性一类，所以用来造成妇人的顺从飞。
教成祭之，牲用鱼，芼之以苹藻，所以成妇顺也。
After the education is completed, a celebration of education is to be held, which is to inform the ancestors that the premarital education has been completed. Fish is used as a sister, and two kinds of aquatic plants, firewood and algae, are used to make soup dishes. These offerings all belong to the阴性 one, so they are used to create women's obedience.
