The suitcase can be carried or dragged. The wheels of the suitcase we usually use are basically located at the bottom of the suitcase, but modern people have designed a new type of suitcase, which is designed to be cylindrical and the wheels are wrapped around the outside of the suitcase. This kind of roller design makes this suitcase better adapt to different terrain, for example, you can easily go up and down stairs by pulling the suitcase directly.
