The smog weather in Nanjing is serious, how to prevent it?

If you can prevent it, you can minimize going out. You can wear a cotton mask when going out to prevent respiratory tract pollution.

Wash your face and bare skin in time when you come back from going out, or rinse your nose with clear water.

Hazy weather minimizes the number of people going to many places, and poor air circulation in some places is likely to cause cross-infection.

And use ZRA! The environment at home and the health of yourself and your family are much better than in the past!
