How do you say where are going in Cantonese?

There are a few ways to say "where are you going?" in Cantonese, depending on the context and level of formality:

Formal:

* 你（nei5）去（heoi3）邊（bin1）度（dou6）? (nei5 heoi3 bin1 dou6?)

* 你（nei5）去（heoi3）邊（bin1）? (nei5 heoi3 bin1?)

Informal:

* 你去（heoi3）邊（bin1）? (heoi3 bin1?)

* 你去（heoi3）邊（bin1）度（dou6）? (heoi3 bin1 dou6?)

More casual:

* 去（heoi3）邊（bin1）呀（aa3）? (heoi3 bin1 aa3?)

Note:

* The numbers in parentheses are the Cantonese tones.

* The word "邊" (bin1) can be used alone, but "邊度" (bin1 dou6) is more common.

* The word "呀" (aa3) at the end is a particle that adds a casual feel to the question.

The best way to choose the appropriate phrase depends on your relationship with the person you are talking to.
