The epidemic situation in Japan is severe, and a catering mask has been introduced. How is it different from ordinary masks? At the beginning of this year, the COVID-19 epidemic swept the world, which not only harmed China, but also affected other countries. Thanks to the efforts of the Chinese people, the COVID-19 epidemic has been well controlled in July and August. In some areas, people have taken off their masks and stepped out of their homes. However, in other countries, they are still suffering from the COVID-19 epidemic, so they have to take masks with them when they go out, but the freedom of masks has not been realized. Wearing a mask for a long time has caused a lot of inconvenience to our life, such as eating out, surrounded by people and relatively dense space, and we dare not take off the mask easily at all, which is our inconvenience. If we take off the mask, it will cause a route of infection.

Recently, the epidemic situation in COVID-19, Japan is gradually expanding. In response to the situation in COVID-19, Japan, the relevant departments called on everyone to wear masks even when eating, and then put out masks for catering to prevent the COVID-19 epidemic from further expanding.

It can be seen that this kind of catering mask introduced in Japan is an ordinary mask with a thin cloth. When using it, the mask above is folded in half and hung on both ears. Just like the ordinary mask, there is an extra layer of cloth. I have to say that Shang Ceng's mask only covers the nasal cavity, but the lower layer can't cover the mouth completely, and can only cover the front of the mouth. It can be seen from the picture that the lateral position can not be completely covered, and the new virus is likely to enter the human body from the side. When eating and drinking, it is inevitable to lift the mask, which will expose the whole mouth to the air and increase the probability of COVID-19 infection. Compared with ordinary masks, it is only a thin layer of cloth that will inevitably contact the mouth with the air when eating. He just covers it from the front, leaving a big gap on the side. I don't think the safety factor of this mask is particularly high. Covid-19 is pervasive, and if he doesn't do a good job in protecting the root cause, he will only continue to expand.

So what we really should do is to reduce the chances of going out, try not to take off your mask when you are outside, never relax at any time, and try to choose a place with few people when eating. I hope the epidemic will be solved quickly so that people can travel normally.
