Ancient girls died before they got married. Why can't they be buried in their ancestral graves?

No matter in ancient times or in modern times, a girl who died before she got married can't be buried in her ancestral grave, because a girl is always from another family, and after she gets married, she is no longer her family. There are also superstitious people who think that girls die before they get married, and being buried in ancestral graves will ruin Feng Shui. Moreover, in ancient times, the idea of son preference was particularly serious. Women had no position at home, and their birth was a tragedy.

In the past, women advocated going out from their fathers to be husbands at home. Without husbands, they had to listen to their sons. They had no time for themselves in their lives. Ancient women died before they got married. If they were buried in the ancestral grave, it would affect the family's fortune and geomantic omen. Therefore, in ancient times, if the conditions were better, they would find a place to bury their daughters not far from the ancestral grave, hoping that their souls would not be too far away. If the conditions were not good, they would throw them into mass graves.

These customs are not only folk, but also in the palace. Not every princess born in the palace can grow up healthily. Some of them died at a very young age, and no matter what the reason for their death, they could not be buried in the imperial tomb. Later, someone specially found a place and built a princess grave to bury these princesses who died before they got married.

In ancient times, there was another custom called yin marriage. They found a dead partner for their dead daughter and son. This custom is really strange and inconceivable. This kind of custom, which takes a lot of manpower and material resources and has no value at all, was later banned, but I still heard that some places still secretly carry out this custom.
