The purpose of reducing the weight of schoolbags: With the increasingly fierce social competition, schoolbags have joined the team of involution. Overweight schoolbags bend children's backs and inhibit their height development. In order to make it easy for every child to carry a schoolbag to school every day, it is imperative to reduce the weight of the schoolbag.

There is no written homework in the first and second grades of primary school, and the distribution of tutoring homework should be reduced in the age above the third grade. In addition, the weight of the schoolbag is also related to the richness of the course to a certain extent. Physical education class, swimming, art and psychology are offered in every school.

For example, can scissors, colored paper, pencil drawing paper, colored pens and other supplies that each student needs for art class be kept in an environmental protection bag at school? Can books other than English, math and English be put in the comprehensive bag and put in the school desk?

According to the survey, many foreign children have only a few sheets of paper in their schoolbags, because the teaching materials and textbooks can be recycled. In China, however, the textbooks of Chinese, mathematics and English are updated quickly, with high utilization rate and serious wear and tear.

For subjects that haven't changed much, such as science, art and music, you can start recycling textbooks. Whether it can be kept by the school is conducive to recycling every class, but teachers will distribute textbooks and teaching AIDS to students before class.
