What is the reason for the custom that brides "return home in three days"?

In fact, this custom has been circulating since ancient times, mainly because of these three reasons.

the first point is to be grateful to parents. As the saying goes, a married daughter is like spilled water. Although her daughter has been married as a wife, she is not out of touch with her parents at home. She still has to go home to see her parents, so that parents can feel at ease when they see that they are doing well. At the same time, she is also thanking her parents for raising them hard. After all, only parents know the sadness. Moreover, going back home now is basically going home the next day. After all, I just married in the past, and the first day is to honor my in-laws. I also need to adapt myself in the new environment. If I go home that day, it will feel bad for my in-laws, as if others have wronged me, so now I basically go back to my parents' home the next two or three days.

the second point is to let parents see if they are happy. Men are afraid of entering the wrong line, and women are afraid of marrying the wrong man. Some men cherish women in every way before they get married, but they may change their appearance after marriage. When they return home, their husbands usually accompany their wives and buy some gifts for their mother-in-law, so that their daughter-in-law's parents can rest assured that their parents will not always worry about themselves when they see that they are doing well, so this is also a reason for returning home. Moreover, the intimate relationship between husband and wife just after marriage is better than before, and it must be revealed between words and deeds? Honey mixed with oil? Feeling, the family will generally observe the son-in-law's manners, and see how he treats his daughter. After all, adults have experienced it and think more than girls.

the third feeling I have is that I feel safe at home. After all, I just went to a strange environment, which is equivalent to being integrated into a new family. I must feel uncomfortable all over, so I paid my respects to my parents-in-law after getting married and went home for a day off, so I can feel more at ease. If I feel uncomfortable, I can talk to my family.
