Because this mask only covers the nose, it is said that this mask is designed to reduce the risk of COVID-19 virus infection when eating. Actually, I don't think this mask is really necessary. You should know that your mouth is exposed during eating, and you will feel the risk of contracting COVID-19, so it is basically useless to simply cover your nose. If you really want to eat COVID-19 at the border, you might as well eat indoors, or everyone has a separate room, so the effect may be better.
This kind of mask not only fails to play a preventive role, but also looks awkward. Many netizens commented that it looks like a clown in a circus. To really prevent COVID-19, we should first learn to wear masks correctly, including nose, mouth and chin. With the warmer weather, the epidemic situation in China has been controlled, and many people are somewhat dissatisfied with wearing masks. Wearing a mask always likes to show your nose, or simply pull the mask to your chin. In fact, there is no way to really stop COVID-19.
Now that the prevention of COVID-19 has reached a critical stage, we should pay more attention to it and wear masks when going to public places. Our country has made great efforts to prevent COVID-19, and I hope you can pay attention to prevent COVID-19 from making a comeback at a critical moment.
