Going back to the door, also called mothering, is a custom of our wedding. Specifically, a woman will go back to her parents' home to visit relatives a few days after her first marriage. Generally speaking, returning home is the third day after marriage, and the second day after marriage in a few areas, and customs vary from place to place.

In ancient times, returning to the door marked that the newlyweds officially became the symbol of husband and wife, which was an essential etiquette. After returning to the door, the groom should change his name to mom and dad after seeing his parents-in-law, and mom and dad should judge the changes of his daughter after marriage and the performance of the groom. At this time, the groom will prepare some gifts for her family. It should be noted that it must be an even number, which means that husband and wife are in pairs and get along well for a hundred years.

In the ancient custom of returning home, on the third day of marriage, or the full moon, the son-in-law would take the bride back to her family. This custom was called "worshipping the door" in the Song Dynasty and "calling uncle" in Hebei. Different places have different names, but the customs are the same. After staying at her parents' home for a few days, she can go back to the groom's house, because there is an ancient saying that there can be no vacancies in the newly-married house for one month.
