At the weekend, you drive your own car, take the whole family to the outskirts to look at the sea, relax, and have a meal together outdoors, then frolic and enjoy the sunshine together, stay in a good hotel late, and prepare for tomorrow’s Travel planning... People’s quality of life is just like the current social development. People are increasingly yearning for a high-quality life, but often ignore some small bacteria, so that you don’t appear more advanced in life.
For example, when you are dining, do you have cleaning for outdoor meals? During the play, are you sure that the surrounding area is very clean? In particular, some people are playing with pets, and they are more likely to get dirty things. More or less, you have been exposed to a lot of bacteria, especially when staying in hotels.
Things that look clean are not. Many of them cannot be identified with the naked eye because bacteria and viruses can only be seen with a microscope.
