Translation:Please write your family name and first name.
that is funny how we say "first and last name," and they say "last and first name," but it makes sense considering how Vietnamese write their last names first!! BUT, DUO, you should count it correct to not repeat the word "name." We don't say "first name and last name" (or last name and first name!), we say "first and last names." aren't we going for the idioms here, not literal translations??
