What are relatives?

Relatives can be divided into biological relatives and legal relatives, that is, broad and narrow sense. Biological relatives, that is, relatives in a broad sense, refer to relatives linked by gender and blood relationship, excluding fictional blood relatives. This blood relationship continues indefinitely, with a wide range and is passed down from generation to generation.

Relatives in the legal sense, that is, relatives in the narrow sense, refer to relatives whose rights and obligations are recognized and stipulated by law, including only a certain range of relatives in the biological sense, and their scope cannot be expanded indefinitely, so their scope in blood is narrower than that in the biological sense. But relatives in the legal sense also include fictional relatives formed by adoption and remarriage.
