When traveling alone, is it better to use a suitcase or a large backpack?

It is better to choose a suitcase when traveling alone. After all, there is no helper to carry things alone. If you carry a big bag by yourself, it will be very heavy and it will be inconvenient to move. As long as the suitcase is large enough for yourself, That’s it. Don’t be too exaggerated. If you have less things, just choose a backpack. This will be more convenient, because the box also has weight, and it is noisy and troublesome to drag it everywhere.
