How about renting a window in the university cafeteria? Do college students like eating out now?
Working in the university canteen window, the money earned last semester is just enough to pay one year's rent, and the money earned next semester is my own. Some canteens have to pay 70,000-80,000 yuan for the whole year, and some canteens have to pay 18%-30% of the turnover for selling rice by credit card. Can kill people!
