Recently, the City College of Southwest University of Science and Technology has launched the "CD-ROM for Welfare" activity after opening the "hot pot window".
After the students have finished eating, they only need to put the "CD" in the tray recycling area, and they can get a fruit or a box of yogurt as a reward.
The students said that it is very helpful to save food and hope that the school will carry out more such activities.
