1. They've been doing that since this started

The Chinese have never been very forthcoming with information.

2. Calming action

The only thing that comes to mind is the citizens can see this as action being taken and it’s a passive calming sort of measure. Better than Wu saying he has a hunch it’s all fine.

3. That kind of bothers me. Like spraying antibiotics everywhere

You're not going to kill the virus, but you're going to give it enough exposure to encourage the emergence of resistant strains.
