How do people consciously take out trash in public places?

You can place a civilized slogan next to the trash can.

In public places, you will find some "civilized warnings" intentionally or unintentionally, such as: No smoking! No sticking your head or hands out of the window! No taking out garbage here! etc.

Slogans refer to propaganda and agitation slogans that are concise and meaningful. Slogans are slogans written in short words that have a propaganda effect.
