Using the verb "xing"
The verb 姓 (xìng) literally means "to be surnamed" or "to have the surname." It may seem awkward at first that there's a verb just for this, but you'll find that it's used quite often in Chinese.
Giving One's Surname
姓 (xìng) is used most often to tell someone your own surname ("family name" or "last name"), or to ask the surname of someone else.
Subj. + 姓 + [Surname]

- 你 老板 姓 李 吗？Is your boss's last name Li?
- 那 个 帅哥 姓 张。That handsome guy's last name is Zhang.
- 我 爸爸 姓 周，我 妈妈 姓 林 。My father's family name is Zhou. My mother's family name is Lin.

Asking Someone's Surname
You can also use 姓 (xìng) to ask people their surnames. You could do this quite directly by saying:
- 你 姓 什么? What is your last name?
However, the formal way to ask has a set form:
- 您 贵 姓 ？What is your honorable surname?
Literally this means "What is your honorable surname?" Use this form to be polite when asking people their surnames.
