An illegitimate son is called a son born to a concubine in ancient times, and it also refers to a son born to a wife other than the eldest son.
The status of an illegitimate son is lower than that of a first son, and generally he can't accept the sacrifices of his ancestral temple and inherit the status of his father and ancestors. Although Dizi and bastard are the same father, the difference between Dizi and bastard is very big because of different mothers and different ages.
the first son is called the son of a true wife in ancient times. Also specifically correct the eldest son born to his wife, "Zeng Yun Shi Di": "The main room is called Di, and the son born to the main room is called Di Zi. When it comes to the first place, the enemy is also, and the words are invincible. " The first son has the right to inherit his father's position, and his position in society cannot be mentioned in the same breath as that of the illegitimate son.
the issue of establishing the official residence is particularly important in the patriarchal society in ancient China. Its basic principle is: "establish a position based on strength, not on merit;" It is expensive to set up a son, not long. " That is: if they are all sons of a married wife, they will be established as elders, regardless of their talents or not; If they are all illegitimate children, they will be established according to the noble status of their biological mothers, regardless of age. This is called "the child is more expensive than the mother".
The difference between a Dizi and an illegitimate son:
1. The right of inheritance is different: judging from the succession of the throne in many dynasties, the Dizi is the heir to the throne that has been decided. If the father has a title, then only the son born of his wife, that is, the first son, can inherit the title of his father. When dividing property, Dizi gets the most.
2. Different family status: Children born in concubines have a very low status and are not valued by their elders. A child born in a concubine's room can't call his own mother his mother, but only the mistress of the family, that is, his father's wife. And the bastard must salute when he sees Dizi. Even if the bastard is older than Dizi, he must salute him when he sees Dizi.
