Dear, no university canteen can spend only 11 yuan a day now.
for example, our school has a reputation for being cheap.
breakfast: a fried dough-strips 1.5 yuan and a bowl of old tofu 1.5 yuan. Here is two dollars.
lunch: one rice or two steamed buns, this is 1 yuan, and the food is a little more expensive. One vegetarian dish is 1.5 yuan and the other meat dish is 2.5 yuan. This is already 7 yuan.
Dinner, like lunch, requires at least 5 yuan, which has exceeded RMB 11, and it is not a big appetite. If you eat a little more, it will be more than RMB 15.
So 11 yuan a day is just one meal in the general university cafeteria and two meals in our school.
