1, different birth mothers
"Di Zi" is the child born to his wife, and "illegitimate child" is the child born to his concubine or aunt. Occasionally, there will be a "flat wife", and the children born to a flat wife are also sons, but the children born to a wife are slightly better than those born to a concubine.
2. Different status
The status of "eldest son" and "illegitimate child" follows their mother respectively. The status of a wife is stronger than that of a concubine, and the status of an illegitimate child is also higher than that of an illegitimate child. In the future, sons will have more rights and interests than illegitimate children, almost priority.
Priority inheritance
1. If the son born to a wife other than the eldest son is called the second son, and the eldest son born to the eldest son is called the eldest son, then in terms of family inheritance, the eldest son takes precedence over the eldest son, the eldest son takes precedence over the second son, and the second son takes precedence over the illegitimate child.
2. If the wife dies or divorces, the wife who continues to marry is called the steproom or the house, and the son born in the steproom is also called the nephew, but the nephew born in Yuanpei takes precedence over the nephew born in the steproom, and the nephew born in the previous wife takes precedence over the nephew born in the next wife.
3. If a concubine gives birth to a son, and then she is recognized as a wife and gives birth to a son, then the son born after her wife takes precedence over the son born when she was a concubine. The status of a son born to the same mother depends on the status of his mother at the time of his birth.
