I currently live in what is called Green Zone. Green Zone's mean our alleyway has zero Covid-19 positive cases. Yes, I mentioned that my alleyway may have a positive case but it is not official until the government confirms it with another test. Hence, we get to keep our Green Zone sign.
Green Zone means we can accept deliveries. Also we can walk around inside, of course with masks. Due to a potential case, the alleyway today was a bit deserted.
Delivery people and "outsiders" are not allowed into this alleyway.
There are many of these Green Zones across the city.
