How do you say I went there before in Cantonese?

There are a few ways to say "I went there before" in Cantonese, depending on the context and level of formality. Here are a few options:

Formal:

* 我以前去過嗰度 (ngo5 yi5 cin2 heoi3 gwo3 go3 dou6): This is a literal translation of "I before go to that place."

* 我之前去過嗰度 (ngo5 zi1 cin2 heoi3 gwo3 go3 dou6): Similar to the previous one, but using "之前 (zi1 cin2)" instead of "以前 (yi5 cin2)" for a slightly more neutral tone.

Informal:

* 我去過嗰度 (ngo5 heoi3 gwo3 go3 dou6): This is the most common and casual way to say it, simply meaning "I went there." The context will make it clear that you're talking about the past.

* 我之前去過 (ngo5 zi1 cin2 heoi3 gwo3): A more concise version of the formal "我之前去過嗰度 (ngo5 zi1 cin2 heoi3 gwo3 go3 dou6)" that is still appropriate in most informal situations.

Using time markers:

* 上星期我去了嗰度 (soeng6 zing1 gai1 ngo5 heoi3 le5 go3 dou6): "Last week, I went there."

* 早幾年我去了嗰度 (zou2 gei2 nin4 ngo5 heoi3 le5 go3 dou6): "A few years ago, I went there."

Choosing the right phrase:

* If you want to sound formal, use the phrases with "以前" or "之前".

* For casual conversation, "我去過嗰度" or "我之前去過" will be perfectly fine.

* Use time markers when you want to be more specific about when you went there.

Remember that Cantonese pronunciation is tonal, so it's important to pay attention to the tones when saying these phrases. You can find audio recordings or pronunciation guides online to help you get the correct pronunciation.
