Does Vietnam have a postal system?

Does Vietnam have a postal system? Well, duh! Of course they do! It's called Vietnam Post. I'm pretty sure they manage to get mail out to most places, like, both in the bustling cities and the more rural countryside, which is pretty amazing if you think about it. I mean, imagine the logistics! But... I do kind of wonder about those really remote areas, you know? Like, way out there. It makes me think of those tiny villages nestled in the mountains or something. It kinda sucks to imagine someone having to hike for ages just to get to the nearest post office. Or maybe they have some other system, who knows? I remember once reading about a village in the Himalayas where mail was delivered by mules… I wonder if it’s similar in some parts of Vietnam? It definitely can't be super convenient, can it? Think about waiting weeks for a package! Ugh. I get impatient if my Amazon order takes more than two days, haha. So yeah, while they have a postal system, I’m betting it's a whole different experience depending on where you live.
