Do foreigners like to write slogans on walls and hang banners on doors?

In terms of place.

Although there are many hip-hop style graffiti on the streets of countries such as the United States, you can hardly see graffiti in those bustling commercial streets.

In politics, except for rallies, marches, demonstrations, and candidates taking to the streets to canvass for votes, banners will not be displayed in other situations, and no such slogans will be written on the walls.
