Daliang's funeral system was inherited from the previous dynasty. Unmarried daughters were not allowed to enter the ancestral grave after death, and people who died violently were not allowed to enter the ancestral grave. Sixth Lady Xu had both. Even if the Xu family loved this daughter the most, she could not withstand the endless rumors. At most, they could only find a cemetery outside and bury her. No one would worship her in the future.
Marriage with the Xiao family was different. After death, she would enter the ancestral grave of the Xiao family. In the future, when Xiao Baoshu married again, Sixth Lady Xu would always be the first wife. If he married a few more, it would be considered a second wife. After entering the Xiao family, he had to first acknowledge the other party's first wife. After giving birth to a few sons, he would also have to offer sacrifices to the first wife.
The more Minister Xu and his wife loved their daughter, the more effective this plan was.
