The bride and groom go back to their parents' home together, so they also have different taboos about staying at their parents' home. In both Han and Manchu, it is a custom for newlyweds to avoid sleeping together when they return to their parents' homes. Manchu allowed his children to live in Xikang, and no other guests were allowed to live in Xikang. But girls and children can't live together. It is said that the newlyweds sharing the same room in their parents' house will make their family's family's way decline. This is also caused by the concept that sexual behavior is unclean and blasphemous. People often think that the woman always suffers from things between men and women. For this reason, the female family always feels a little depressed psychologically. Besides, if the mother's family and the husband's family don't belong to the same lineage, how can we provide a place for the husband's family to carry on the family line in the mother's family room? If she was really pregnant at her mother's house, wouldn't she take her "human potential" and "financial potential" to her husband's family? The bride's family will definitely decline because of this. Therefore, it is absolutely forbidden for young couples to share the same room at their parents' home, which is the idea under this custom. However, both in the Han nationality, there are also many places where it is not taboo for newlyweds to sleep together at home.
