A simple and direct way to indicate that you or someone is going to a specific place or has arrived at a specific place is to use the verb 到 (dào).
The verb 到 (dào) is used to talk about arriving in places.
Subj. + 到 + Place
For these examples, it's straightforward to think of 到 (dào) as simply meaning "to arrive."
In some examples translating 到 (dào) as "to arrive" doesn't work as well and you might need to expand your understanding of exactly what 到 (dào) means. That's what we'll examine below.
If you are going to a place to do something else, you can first use 到 (dào) to indicate where you're going, then add another verb after that. This has the meaning of "going to the place to do something," and it's one case where the "arrive" translation doesn't really work anymore.
Subj. + 到 + Place + Verb Phrase
You might be wondering: can I just use 去 (qù) instead of 到 (dào)? For sentences like this, yes, you can. But native speakers will frequently use 到 (dào) in this way, so it's still good to be familiar with this pattern. If you want to sound more native, you should use it too!
Sometimes it can be hard to figure out exactly which word to use in Chinese to mean "go." 到 (dào) is used when you talk about arriving at a place, emphasizing the destination. 去 (qù) is used when you are going to a place. The exact meaning is "to go," and it emphasizes getting to somewhere. 走 (zǒu) is used when talking about "leaving." The emphasis is on getting away from a particular place.
