Mouth, shoe rack, towel rack, etc
It is very convenient to fetch water and take a bath in the dormitory. As long as there is a "one card", you are not afraid to go anywhere at school. Even the key to the bedroom door is designed uniquely. It looks like an ordinary plastic shell with a special magnetic card on it. Just "brush" the door above the door handle and it will open, which is very safe! Students can check in with their bags, comparable to star-rated hotels!
