Not expensive. The goal of the canteen of Hunan University of Science and Technology is to provide convenient, healthy and affordable catering services for teachers and students, rather than taking profit as the main purpose. The school will try its best to control the cost and ensure that the price of the canteen is relatively low, and there are more people dining in the canteen every day. A large number of dining demands can bring economies of scale and reduce the cost of purchasing, processing and operating ingredients, thus reducing the price of canteens.
