How to ask "Did you receive it?" in Chinese

你 (you) + 收到 (receive) + 了 (completed action marker) + 吗 (question particle). The particle 了 indicates the action is complete, so you're asking if it has been received.

Use this when you've sent something—a message, file, or package—and want to confirm it arrived. It's casual and common in digital communication. Avoid using it in formal written correspondence; a more polite form might be needed.
