1. Sell snacks and deliver them to your door. When selling dormitories in universities, there is basically a person who sells snacks, because many universities have fewer courses and always like to stay in the dormitory without classes. What should I do if I am hungry? Do you really want to have a classmate who sells snacks, especially the kind that can be delivered to your door? There are many people who will cook dramas in the dormitory. Snacks are also standard during the drama, but no one wants to go out to buy things during the drama. Your snack bar is their first choice. Instant noodles are also very popular at night, because college classes end early, some of them go to eat after class at 5 o'clock, and it is common to eat midnight snacks at night. Remember to sweep the building first, leave your contact information with others, and let others think of you as soon as they want to eat snacks.
2. Printing services. Printing services in universities are also very profitable, because many clubs, many classroom materials and even homework need to be printed. It costs a dollar to print one. Think about so many students in the whole school. Many students print several or even dozens of copies together, which is very profitable. You just need to prepare a printer and buy some A4 paper.
3. Sell formal clothes. The business of selling formal clothes in universities is also very good, because there are many club interviews just after entering the school. If you want to run for minister or deputy minister, you need to wear formal clothes for the interview. Formal attire is required for graduation and campus interview. There are many opportunities to wear formal clothes in college, but many people don't wear formal clothes before coming to school. In fact, there are only a few versions of formal clothes. What matters is size. You can show them to others, and then others can order them to help them get the right size.
