Background introduction:
In the ancient times, the prince in the palace was assigned a marriage partner at birth and could not refuse the marriage unless both parties reached an agreement to cancel the marriage.
Whether it is a prince's family or a commoner's family, if there is a concubine in the family who wants to be promoted to the position of head wife, she must go to the Yamen to report.
Then the concubine sits in the high hall, and the husband bows nine times and kowtows nine times. The different things offered in the nine kowtows need to be increased gradually, and they must all be written down. The last kowtow requires one's own human rights.
If the concubine does not agree to marry her husband, then the two will finally reconcile and divorce. If the concubine agrees, then they can become husband and wife, and then the head wife will be in charge of the family.
After becoming an official couple, the husband must abide by the three obediences and the four virtues, while the wife only needs to not go out and steal men.
A concubine cannot raise children. This is a rule. If a concubine wants a child, she must leave her husband's family. All future raising will be supported by the concubine herself, unless someone in the husband's family is willing to have the concubine's child.
