1. It's convenient to raise your hand all day.

2. Take the elevator in a civilized way-go upstairs and downstairs.

3. Go down first, then up, first out and last in;

4. Take care of public facilities;

5. The elevator is convenient for you, me and him!

6. Love depends on you, me and him!

7. Civilized riding is convenient for you and me.

Give each other humility and broaden your horizons.
