So I never really noticed, but does Vietnam have their own social media site? I know China and some other countries have their own social media sites, so it made me wonder if Vietnam did as well. Do they?
I did a search, and according to a site called The Worker, the most popular site is Facebook, and a site called Zalo. I'm guessing it's only available in Vietnam. I looked it up too, and it seems to be a chat app. So probably competes with Facebook Messenger.
