Is the party in three days, three days, or three days? What is the basis and origin?

Return to the door on the third day. Mothering relatives in the province, a custom handed down from ancient times, can also be called being a guest, going back to another home (in Minnan) or going back to the Three Dynasties. It means that the newlyweds bring gifts to the woman's house on the third day of marriage, and the woman's house must also prepare a banquet at this time (usually at noon, it is called a mother-in-law banquet or a son-in-law). After the mothering, the matchmaker's work is over, and the man must give the matchmaker a gift.
