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. 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.
Although 姓 (xìng) is equivalent to the English expression "last name" this can be misleading, since in Chinese the 姓 (xìng) comes before the given name. For this reason, it may be easier for you to think of 姓 (xìng) as meaning "family name" or "surname".

Asking Someone's Surname
You can also use 姓 (xìng) to ask people their surnames. You could do this quite directly by saying:
Nǐ xìng shénme?
What is your last name?
However, the formal way to ask has a set form, and this is almost invariably the way people ask:
Nín guì xìng?
What is your honorable surname?
Literally this means "What is your honorable surname?" Use this form whenever you ask someone their surname in Chinese.
