Every school day, we use schoolbags to carry all of our things to school. They are a big part of our lives. But have you ever thought about the history of the schoolbag?
In the Han Dynasty, students in old-style private school used bamboo boxes to carry books to school. People think that the bamboo boxes are the earliest schoolbags. There were usually two or three layers(层) in the box. Kids put different things like books, brushes, ink stones(砚) and paper in the boxes.
Hundreds of years later, people developed a new kind of schoolbag called budai. Budai was lighter than the bamboo box. With the founding of the People's Republic of China, military rucksacks(军用帆布包) became popular. Many people carried them when they were in school. Ask your grandparents or parents about these bags. Maybe they can tell you about their experience of carrying them when they were in school.
A new style of schoolbags is used now. Many of them have pictures of cartoons or pop stars. And they are more comfortable to use. Some students would like to use wheeled(带轮子的) bags to carry heavy things and others carry backpacks.
Schoolbags are still changing. Do you know what future schoolbags will be like?
