Do I need to wear a mask to take the bus?

Yes, you need to wear a mask.

Because the epidemic situation is not as serious as before, buses are crowded and closed spaces, and taking buses is still a low-risk behavior of epidemic infection. Low risk does not mean no risk, so we should wear masks consciously and scientifically.

You should not only take the bus, but also wear a mask and take protective measures when you have to go to crowded places.
