What is meant by the term "marriage in the underworld"? When did this custom start?

The marriage has been practiced since ancient times

When it comes to the marriage, many people are no strangers to it, especially the old people in the village, who know it very well. Now is the new era of the 21st century, the marriage is very rare, but in some places there is still a marriage. Underworld marriage is to find a spouse for the dead, for example, there is a person died, did not marry a wife in life, the family does not want him to be too lonely, will also find a similar time of death of the opposite sex, the two of them buried together. Most of the time in ancient times it was because two men and women who had been engaged to be married died, and the family felt that it would go against something if they weren't together, so they would bury the two of them together. And nowadays some places just want to simply find a companion for the person who has passed away.

Planned marriages are rare now

Planned marriages sound scary, but they are actually just that. It's just that some people now use it as a means of earning money, getting the other person to pay money and then allowing the person to be dragged away and buried together. How can I put it, there is also a kind of superstition, people have passed away, will they still feel lonely. It is only that the family wants to do the things that were not done in life to finish, so that the heart will also feel better. Underwedding still exists in some remote places, especially for those who are more feudalistic in their thinking and older, they feel that such behavior is normal and don't think there is anything wrong with it.

Plutonian marriage is not acceptable to everyone

Some people think it is particularly outrageous when they hear about plutonian marriage, and how can there be a daughter-in-law for someone who has passed away. Usually in ancient times, this kind of behavior is especially powerful, especially the rich family. If the young man in the family died, they will buy a girl who died at about the same time to be buried with their own children, it can also be said that it is to figure a peace of mind, in fact, there is no role at all. From ancient times to the present, the marriage has always existed, but with the progress of society, the times have changed, many people do not believe in this, nor do they care. Underworld marriage is also considered to be handed down, as for the good and bad, it is not good to comment.
