My friend, I think you can sell some snacks at the newsstand. You must know, after all, college students buy newspapers and magazines and read them online less. It would be better to sell snacks. After all, college students, both men and women, like to eat snacks. I hope you can promote the sale of snacks, leave open stores and deliver them to your door, because friends should know that college students don't like to go out now. In this way, you can improve your competitiveness. Although hard, you have improved your competitiveness compared with other snack sellers. I suggest you ask a friend to drive with you, so that you can take care of each other. There are also friends who can sell some small computer accessories, which do not occupy space and have a market. After all, college students use computers more now, and there is a market. These are all relatively marketable in universities. I hope my advice can help you. Finally, my friend, I wish you success.
