But school bans the take-away food, on the one hand, the school wants students to consume in the canteen, on the other hand, they also want to make sure the students’ healthy. Most students choose to order the take-out away food in secret.
In my opinion, the school should change their mess for some time, they need to cook the food that is suit to the students'taste, they can increase the kind of food to attract the student' interest. The take-away food will be reduced naturally.
