Qian' an college canteen can't deliver meals. The most practical problem is that the school is not allowed to ride bicycles. Who will take the order and how to deliver the food? The school doesn't allow it either. The purpose of the school canteen itself is to provide a good dining environment for students and serve them. Its price, quality and recipes have been supervised and scientifically matched by the school. It is a full-time canteen specially set up for growing students, which is different from restaurants and ingredients in society. If you serve the outside world and take out food, it will violate the purpose of the canteen itself. At the same time, it is meaningless because it is profitable.
