Will it really harm your mother's house to sleep together? It comes from the concept of family.
The idea of sleeping together at home.
It is normal for husband and wife to live in the same room, but there is an unreliable saying that if they sleep together at their parents' house, it will be very bad for their parents' house, and even have a great impact on their brothers and sisters, family fortune and property. However, such statements are based on conservative feudal thoughts. In the past, people of the older generation were stubborn and thought that sharing a room with men and women was a dirty thing, so they were not allowed to share a room outside. In fact, the bride's family, that is, the woman's family, will not say that she is not the bride's family after marriage, nor will she lose too much because of the same room. These are simply nonsense.
The idea of sleeping together at home also depends on local customs, which will vary from place to place, but there are also many places that sleep together at home will be very bad for the family, but these will not have too many bad effects, because many couples will sleep together when they return to their parents' home, which is also derived from the concept of family.
