For students, safety is hard to prevent, especially some younger students, but as long as you do the following, nothing will happen.
One, go swimming. You must be accompanied by an adult, and you can't go alone with your classmates, otherwise you will lose your life in the event of drowning.
Second, you can't play with fire. Especially around flammable materials, such as lawns, Woods, forests, zoos, mountains … you can't play with fire in these places, and you can't play at home.
Third, the problem of diet. You can't eat at home, you should eat in order, the same, the same, and you can't wolf it down. Outside, you can't eat indiscriminately. When you buy something, you should look at the production date and shelf life in case it expires. You can't eat what others give you. Don't eat wild fruit on the mountain, it may be poisonous.
