How about using the stairs?

As I had a day off today, I went to the city library and studied there until evening. Captured this in front of the lift. The person using the stairs looks happy. It also suggests in Japanese that you use the stairs for your bodies and for the environment. 

The city library is relatively new, opened in 2020, near the high school I went. A lot of students come to study after school. Every time I come to this library, I feel that it would have been nice if there had been this library when I was a high school student!
