At present, university canteens are sold according to the dishes. If you want to eat meat dishes, you need 7 ~ 12 yuan for almost a meal, and 5 ~ 7 yuan for only vegetarian dishes. Of course, there are also some poor families whose living expenses are not high. I have a classmate who eats two steamed buns and a duck egg for a meal, which can be done for almost 3 yuan.
