How to say "Who?" in Chinese

谁 (shéi) is a single-character question word meaning "who". It can stand alone as a question or be placed in a sentence to ask about the subject or object.

Use 谁 to ask about a person's identity, similar to English "who". It is neutral in register and can be used in both formal and informal settings. Avoid using it with a rising tone if you are not asking a question, as it may sound like a statement.
