What does the door-to-door son-in-law mean?

Door-to-door son-in-law is also called stepson-in-law, which means that after a man and a woman get married, the man goes to the woman's house to get married and settle down. This kind of marriage is mostly because the woman has no brothers and sisters and recruits a son-in-law to carry on the family line. When a man goes to a woman's house to get married and settle down, he should take her surname. This is called "inserting the door backwards", "the boy can't change his name" and so on.

After the founding of New China, in order to change the concept that men are superior to women or women are superior to men, gender equality and monogamy were strongly advocated. The traditional "inverted door" has also been greatly weakened, with only residence and children's surnames.

Marriage and adoption of men and women are two different marriage modes, and all roads lead to the same goal. Therefore, two people live together with the common goal of being good for their children. However, influenced by traditional concepts and social values, there are still differences between them. To some extent, men in adoptive marriages may have to bear more pressure and make more efforts.

Generally speaking, adoptive marriage is influenced by some objective factors, and there is asymmetry between the two families, which is a marriage model adopted in order to achieve balance. Therefore, compared with the marriage mode of one man and one woman, this marriage mode has certain particularity, which requires both families to reach an understanding and overcome difficulties, and the adopted man bears greater responsibility.
