How do you say where are from in cantonese?

There are a few ways to say "where are you from" in Cantonese, depending on the level of formality and context. Here are some options:

Formal:

* 你来自哪里？ (nei4 zoi6 lai4 hei2?) - This is the most common and formal way to ask. It literally translates to "where do you come from?"

Informal:

* 你系边度人？ (nei4 hai6 bin1 dou6 jan4?) - This is more casual and literally means "where are you a person from?"

* 你来自边度？ (nei4 zoi6 lai4 bin1 dou6?) - This is also a casual way to ask, similar to the formal version but using the word "边度" (bin1 dou6) instead of "哪里" (hei2).

* 你家乡喺边？ (nei4 ga1 soeng1 hai6 bin1?) - This literally means "where is your hometown?" and is a more informal way to ask.

Note: The tone marks are important in Cantonese as they change the meaning of the word.

You can also use 你边度人？ (nei4 bin1 dou6 jan4?) which is a very casual way to ask "where are you from?".

It is always best to choose the appropriate level of formality based on the situation and the person you are talking to.
