A good place to be a door-to-door son-in-law is to relieve the financial pressure of the man's parents. Door-to-door son-in-law used to be called "door-to-door son-in-law to support the elderly" in some places, which meant that her parents-in-law had no sons and needed a son-in-law to support the elderly and died. With the development of society and the increase of population mobility, this concept and method are gradually changing. Now there are many families with only daughters and no sons, and the essence of the present "on-site son-in-law" and the previous "on-site son-in-law" has also changed greatly. Judging from the current situation, even if you become a door-to-door son-in-law, it may not be your parents-in-law's idea, but it may be because of your working relationship with your girlfriend. As a door-to-door son-in-law, you can usually spend more time with your parents-in-law, and they will also be more concerned about your marriage and the care of your children, which will relieve your parents' financial pressure to some extent.
The disadvantage of being a door-to-door son-in-law is to be patient in the ideological work of parents. In the past, there were generally more boys who worked as sons-in-law for the elderly at home, and their economic conditions were relatively poor. Parents are also forced by economic pressure to let their sons be door-to-door sons-in-law. This concept of compulsion is deeply rooted in parents' minds. Therefore, if you want to be a door-to-door son-in-law, you should first do ideological work for your parents, so that they can change their ideas and accept you ideologically. After marriage, the door-to-door son-in-law can't "marry the daughter-in-law and forget the mother." He should go home often to make his parents feel that they are not raising their sons for nothing.
