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.

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?Nǐ xìng shénme?What is your last name?
However, the formal way to ask has a set form:
- 您 贵 姓 ？Nín guì xìng?What is your honorable surname?
Literally this means "What is your honorable surname?" Use this form to be polite when asking people their surnames.
