Relating to your small businesses, a lot of them will have their own shippers to save on having to pay the cut from a food delivery app. When I needed a reusable mask after the ones I had were running out at the end of my quarantine, I just messaged a guy who had his online business and an hour later my shipment had arrived (he used an inter-city courier, but you get the point). Somehow being in a city of 8 million makes you feel in more of a community than being in a city of 150k.
I've had a bakery message me to ask if I was in the mood for ordering cupcakes when they still had extra at the end of the day (and I was). A few weeks after a new japanese ramen restaurant told me they only offered take out, they messaged me to tell me that they now offered delivery. It's an amazing channel for businesses to reach their customers.
It's also a really convenient place to get news, because since all news sources are government approved then there's no fake news to worry about. (and by fake news I mean sensationalist stuff, not anything serious relating to politics. I obviously understand the shortcomings with such a system when it relates to criticism of the government)
It's also really nice because you don't have pseudo-science crap on your feed (since sharing that stuff is a fineable offense). Although you still have to watch out for the moms in their Zalo groupchats.
