Chinese surnames or family names are written "before" the first name or given name. Therefore, someone named Wei () from the Zhang () family is called "Zhang Wei" (张伟) and not "Wei Zhang". Chinese women generally retain their maiden name and use their name unchanged after marriage, but in modern times in some communities, some women may choose to attach their husband's surname to the front. Chinese surname is patrilinear where the father's surname is passed on to his children, but more recently some people have opted to use both parents' surnames; although this practice has increased in recent times, it is still relatively uncommon in China, with those who adopted both parents' surnames numbering at only 1.1 million in 2018 (up from 118,000 in 1990).
