Chinese family names are patrilineal, passed from father to children. (In cases of adoption, the adoptee usually also takes the same surname.) In current Chinese practice, surnames are not changed upon marriage. However, in places with Western influence such as Hong Kong, women may (legally or informally) adopt their husband's surname. Traditionally Chinese surnames have been exogamous.
