The subtle education of children takes advantage of their active exploration. Environmental education is a subtle way of education, and life is the best textbook. It will tell us that children's existing life experience, self-care is to take care of children. We should start with the child's personality, find the child's rules in class, and have more original opinions in the activities. Recognizing this, when creating a classroom environment, it will be more suitable for children's preferences, and children will be more willing to enjoy the feelings brought by the classroom and achieve the purpose of education.
