There is a strange custom in the wedding of the upper class nobles in the Spring and Autumn Period: a woman cannot live with her husband for the first three months after she marries her husband's family. Only after the "March Temple Fair" ceremony, that is, the ceremony of visiting her husband's ancestral temple, can the woman's wife's identity be confirmed and both men and women formally get married. Most modern works on the pre-Qin marriage system have not paid enough attention to this long-lost ancient ceremony and related expositions by ancient scholars, and the content, nature and significance of this ceremony have not been accurately and thoroughly explained so far. In view of this, this paper intends to make a comprehensive and systematic investigation of the temple-visiting ceremony in March, and try to put forward a new explanation of the creative intention of this ceremony by using ethnological materials. First, the custom of "seeing the temple in March" is the most important basis for us to study this ritual system in the relevant records of pre-Qin literature and two general descriptions of the ceremony of seeing the temple in March in the Book of Rites, Ceng Zi Wen. "Zeng Ziwen" first quoted Confucius as saying: "Marry a woman, keep a candle for three nights, and think about parting; Take a woman home, don't be happy for three days, think about your loved ones. See the temple in March and call it' Frye'; Choosing a Japanese name is also the meaning of becoming a woman. " Although this passage may not really come from Confucius, it contains a very clear idea, that is, "see you in the temple in March" and so on are all important rules in weddings in Confucius' era. "Seeing the temple in March, named' coming to wife'" means that a woman has been married to her husband's family for three months and held a ceremony to worship her father's ancestral temple. ......
