Compare with English

In English, you can place the “when” part either at the beginning of the sentence or after the comma, like this:

When you are nervous, what do you do?
What do you do when you are nervous?

But in Chinese, “…的時候的时候 de shíhòude shíhou” is considered a time word, and is typically used before the subject or directly after it. Therefore:

你nǐ緊張jǐnzhāng的de時候shíhòu會huì做zuò什麼shénme？ 你nǐ紧张jǐnzhāng的de时候shíhou会huì做zuò什么shénme？ O

緊張jǐnzhāng的de時候shíhòu你nǐ會huì做zuò什麼shénme？ 紧张jǐnzhāng的de时候shíhou你nǐ会huì做zuò什么shénme？ O

你nǐ會huì做zuò什麼shénme緊張jǐnzhāng的de時候shíhòu？ 你nǐ会huì做zuò什么shénme紧张jǐnzhāng的de时候shíhou？ X

When it is written or in formal situations

的時候的时候 de shíhòude shíhou will be shortened to simply 時时 shí
