If you have money, opening a hotel is the first choice! But it depends on the hotel distribution and environment around your university! Suggest doing a market survey! In addition, open a four seasons barbecue stall and remember to buy a good menu. I asked before that it was 50 thousand! As long as it is delicious, it will be rich! Or tea shops, cafes, places like love, this investment is not big, but it should be carefully cleaned up! This is all about the environment. Not many people really drink! If the investment is small, set up stalls and sell bags wholesale. If it is small, you can do it in the dormitory, open an online shop, open a snack bar and sell supper early, but it is very hard, because everyone needs to send it upstairs and ask for manual adoption!
