Language/Mandarin-chinese/Grammar/Questions-with-不-(bù)

Closed interrogative questions in Chinese can also be formulated with 不 (bù).

This is done by adding an affirmative-negative structure at the end of the sentence.

Structure

Verb + 不 + Verb

When placed before a falling tone character, 不 is read bú.

This expression can be attached to the end of a sentence to form a closed interrogative sentence.

Closed interrogative sentences await confirmation or acceptance of what has been said.

In English "isn't it?" or "OK?" are often used for closed interrogative sentences.
