Blu,
Wuhanites who wore masks pre-covid to reduce pollution wore then outside, where the pollution is. And not every location in Hubei was polluted every day, so there must have been plenty of times when public mask wearing was limited to those who felt ill.
Inside, around family, friends , neighbors, coworkers, etc, they did not wear masks unless feeling ill.
No one wore masks while eating in public.
After covid, everyone wears masks outside, same as before , but even more so, even if pollution is low. No one eats in public anymore, and no one works at the remaining essential jobs without a mask, gloves and plentiful hand sanitizer.
Does that answer your question?
