Why are children born before marriage illegitimate? After marriage, is the child born in the office?

The author of this novel is totally making it up. He began to make it up before he knew history. What is the truth? What is a concubine?

It's not a question of getting married and having children, but whether his mother is the right wife for this family. A suitable wife is the wife who is in charge of the whole family affairs. All wives and concubines have to listen to her. The first son she gave birth to was the first, and the other three or four rooms were concubines.

First of all, we must understand a very important condition: in the feudal society in the past, the wife had to be a matchmaker, and after all kinds of etiquette, the so-called unmarried birth could survive. Not married, sir, son? Can marry into the house aboveboard? Can a wife be aboveboard? When a large family marries a wife, they must be innocent first, preferably a big lady who has never been out of the closet. They have to go through three books and six rituals (popular science: "three books" refers to the documents used in the process of "six rituals", including letters of appointment, gifts and welcome letters. "Six Rites" refers to the whole marriage process from marriage proposal to marriage. "Six Rites" means accepting gifts, asking names, concubinage, accepting gifts, inviting parties and welcoming relatives. ),

A child born outside without a door, even her son, cannot enter the house at all, let alone be an illegitimate child. Big families pay attention to bloodline, and they don't marry illegitimate children without going through three books and six rituals. Who knows whose child you gave birth to? It is taboo to have children before marriage. In ancient times, marrying a concubine was a small sedan chair that entered the house by a side door at night. Her children are illegitimate children. They don't want to be illegitimate children at all.
