The bride and groom go back to their parents' home together, so their accommodation at their parents' home also has different taboos. In Han and Manchu, it is a custom for newlyweds to avoid sleeping together when they return to their parents' home. Manchu allowed their children to live in Xikang, and other guests were not 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 access decline. This is also caused by the concept of unclean and blasphemous sexual behavior. People often think that women are always troubled by things between men and women. Because of this, female families always feel a little depressed psychologically. Besides, if the bride's family and her husband's family are not of the same clan, how can we provide a place for the husband's family to carry on the family line in the bride'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 house? The bride's family will definitely decline because of this. Therefore, it is absolutely forbidden for young couples to share the same room in their parents' house, which is the idea under this custom. However, both of them are in the Han nationality, and there are many places where it is not taboo for newlyweds to sleep together at home.
