Take-away food delivery is prohibited in universities, one is to cultivate students' practical ability, and the other is to ensure the food safety of students' meals. On the first point, many students order food online in the dormitory, which is a bonus in the Internet age, but it makes them lazy invisibly. On the second point, the school can urge the school canteen to be rectified, but the canteen outside the school is beyond its reach. Although the off-campus canteen has certain security, it is much worse than the on-campus canteen.
