1. First call the canteen for feedback. If you encounter an unreasonable situation in the canteen, you are embarrassed to express it on the spot. You can take a photo while eating, and then call back and give feedback to the backstage staff.

Secondly, you can send your opinions to the feedback box, and the school will contact you when it sees them.

3. Finally, there is the school advertisement wall. Just type it directly and send it to the school advertisement wall, which will make the canteen notice your opinions and then make the canteen make changes.
