From what I've been hearing, the big problem for lots of people stuck under lockdown is simply getting groceries/food deliveries at all. The government isn't letting delivery people work, and the military response to distributing food isn't filling the gap (maybe if you are lucky, you'll get some pork and bai cai form the gov at your door). So that would suck, if true. I also rather guess experiences differ between richer districts and poorer ones.
