Rule structure

还是 (háishi) links alternatives in a choice question, including one embedded in another sentence. An embedded question can follow 不知道 (bù zhīdào), “not know,” or 想知道 (xiǎng zhīdào), “want to know”: the speaker reports not knowing or wanting to know rather than asking the choice question directly. Ordinary affirmative alternatives use 或者 (huòzhě).

Examples

我不知道他喝茶还是喝咖啡。

Wǒ bù zhīdào tā hē chá háishi hē kāfēi.

I don't know whether he drinks tea or coffee.

我不知道他是老师还是学生。

Wǒ bù zhīdào tā shì lǎoshī háishi xuésheng.

I don't know whether he is a teacher or a student.
