Right now, various places are resuming work and production. The epidemic prevention and control has reached the most strenuous and critical stage, and masks are needed everywhere.

Chinanews client, Beijing, August 7 (Zuo Yukun) If you say that wearing a mask in this sultry summer is a kind of "torture", then what is more cruel than "torture" is the mask you wear so hard. Useless.

It's good to be able to live-many people's expectations for this year. Looks like lying flat on the spot, not thinking about making progress, but actually waiting for the opportunity to make progress.

Wearing a mask has a good preventive effect on respiratory infectious diseases such as new coronary pneumonia, influenza, tuberculosis, etc. It not only protects oneself, but also benefits public health. Especially in the prevention and control of the new crown pneumonia epidemic, masks have played an important role.
