Kinship is a kind of address for relatives.

The word "relative" has a long history. The Book of Rites in ancient China said: "Familiarity belongs to the family", and Liu Xi in the Han Dynasty said: "Familiarity, concealment, concealment." "Genus is continuous, and goodness is continuous." Although these explanations do not reveal the social attributes of relatives, they all show that there is a close relationship between relatives.

Relatives are widely seen in the law, starting from the explicit law. For example, the Ming Law contains provisions such as "relatives steal from each other", "relatives fight against each other", "relatives commit adultery" and "marry relatives' wives and concubines". Since the end of Qing Dynasty, all the drafts of civil law and the draft of civil law of Kuomintang government have a series of kinship.
