One day, a group of dirty bacteria babies happily walked out of the bacteria castle and went out to explore. Bacteria said to Chang happily: let's go, let's have a good time in the children's stomach.
The bacteria baby finds Mingming's dirty nails, happily jumps in, rolls in the cracks of the nails, eats dirty things, and is ready to go into Mingming's stomach to have a good play.
When I went to wash my hands at this time, the bacteria called out to me: bad, run away! But it's too late. The bacteria are all washed away by water and soap bubbles.
Other bacteria baby see soap bubble and water, quickly said: what a terrible weapon, we dare not come next time!
Parents ask their children to hold out their hands and explain to them that there are a lot of bacteria on our hands. They are very small and we can't see them with our eyes, but bacteria will make us sick. However, don't worry. Bacteria are most afraid of water and soap bubbles. As long as we use water and soap and carefully scrub our hands, we can get rid of bacteria and won't get sick. Children should wash their hands frequently and talk about hygiene!
