How do you say where are from in Chinese?

There are a few ways to say "Where are you from?" in Chinese, depending on the formality and context:

Formal:

* 您来自哪里？ (Nín lái zì nǎ lǐ?) - This is the most formal way, used when addressing someone older or in a professional setting.

* 您是哪里人？ (Nín shì nǎ lǐ rén?) - Another formal option, meaning "Where are you from?" literally.

Informal:

* 你来自哪里？ (Nǐ lái zì nǎ lǐ?) - This is the casual way to ask someone where they are from, used with friends or people you know well.

* 你是什么地方的人？ (Nǐ shì shénme dìfang de rén?) - This is another informal way to ask, meaning "What place are you from?".

More casual:

* 你是哪里的？ (Nǐ shì nǎ lǐ de?) - This is the most casual way to ask.

* 你老家在哪？ (Nǐ lǎojiā zài nǎ?) - This literally means "Where is your hometown?", and it's often used to ask about someone's origin.

It's important to choose the appropriate level of formality based on the situation and your relationship with the person you are asking.
