Every school day, we use schoolbags to carry all of our things to school.1.But have you ever thought about the history of the schoolbag?

In the Han Dynasty, when old-style private schools were opened, students used bamboo boxes to carry books to school.2.. 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.3..For example, in The Legend of White Snake, Xu Shilin caries a bamboo box to the capital to take an exam. And in the movie The Chinese Ghost Story（倩女幽魂），the scholar Ning Caichen also carries a bamboo box.

Hundreds of years later, people developed a new kind of schoolbag called the budai, or “hip-pocket”. The 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.4.Maybe they can tell you about their experiences of carrying them when they were in school.

A new style of schoolbags has been produced in recent years. Many of them have colorful and fashionable designs on them, such as pictures of cartoons or pop stars. And they are more comfortable to use. Some students pull wheeled bags filled with heavy textbooks and others carry backpacks5..
