What's the significance of "menstruation doesn't accept it and menstruation doesn't send it" in rural marriage customs?

There are many exquisite wedding customs in rural areas, one of which is called "menstruation doesn't want it, menstruation doesn't send it". So what is the exquisite? In fact, this is a culture of China people. Let me give you a specific explanation:

First, refusing to meet is actually the traditional cognition of married women:

My aunt belongs to a very close family in China, but why can't my aunt take over? This is because this person has a saying that the married girl deserves water. This is a traditional concept in ancient China. Modern people may not understand it very well. Let me explain something to you. In ancient times, the family had many rules. After jane doe got married, she had to get permission from her parents-in-law to go home. In other words, as a wife, she can't have her own ideas, and she can't rely on her former family, so this family won't pay too much attention to this married girl.

Second, it is also a family concept that aunt doesn't send it:

Although menstruation is a very close person, because menstruation is a married woman, and if menstruation gives it, there is a very bad moral: that is, the daughter-in-law can't get it back! In fact, this is superstitious, but in ancient times, people were superstitious. If they want to give away a married woman, it is obviously unlucky, and it seems that they can't go home yet. Therefore, aunts can't see their relatives off, and this custom has continued to this day.

As can be seen from the above conclusion, Aunt menstruation is actually a married woman, so there are some things that cannot be done in marriage. Plus, Aunt menstruation is a close relative, so she can help with housework at home and help with some things that need to be prepared for marriage, so basically, Aunt menstruation will not be idle.
