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

If it is prevented, you can go out as little as possible, and you can wear a cotton mask when you go 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 clean water.

Smoky weather should minimize going to crowded places, and poor air circulation in some places can easily lead to cross-infection.

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