With the progress of society, the styles and materials of schoolbags have changed greatly. The kind of military canvas bag that my brother and sister used when they were at school, with an oblique flip. When I first started school, I used a bag sewn with rags, or my mother sewed it herself, which saved money. There were not many books at that time. There is only a Chinese book and a math book in the small bag, as well as a pencil box and some exercise books. In the third grade, leather schoolbags cost about ten yuan each. Dad also bought me a black diagonal flip bag, which made me happy for several days. Polishing the schoolbag every day attracts a lot of envious eyes.
The spring breeze of reform and opening up has spread all over China. With the spread of this spring breeze, the social economy continues to develop, and people's living standards are getting higher and higher, which is also reflected in the small book bag. Rag schoolbags and leather schoolbags with monotonous colors and simple styles have become history. Instead, it is a bag with novel style and different materials. The one-shoulder diagonal style became a backpack. Bags come in a variety of colors, with prices ranging from tens to hundreds. And brand bags. The functions of schoolbags are more and more, the things in schoolbags are richer and richer, and the burden on students' shoulders is heavier and heavier.
