What is the name of the advertisement on the door?

It's called a poster. It's also called a poster.

But if you break it down,

Posters are mainly written, with more words, and posters are mainly pictures.

"Poster" is interpreted according to its meaning, "moving" is to guide attention, and "posting" is to post, that is, "posting for attracting attention". The English name of the poster is "Poster", which means the placard displayed in public places in the Oxford English Dictionary. In the advertising dictionary published by "International Textbook Publishing Company" in London, posters refer to printed advertisements posted on cardboard, walls, large wooden boards or vehicles, or displayed in other ways. It is the main form of outdoor advertising and one of the oldest forms of advertising.

Some people interpret the meaning of posters according to their root structure and anecdotes, and think that posters are converted from "posts", which means posts, so posters refer to all notices posted on posts.

Posters have another name in China, and no Chinese dictionary has given a special explanation to the word "poster". However, it is said that during the Qing Dynasty, foreigners parked foreign goods on seagoing ships at the coastal wharf in China, and put up posters in conspicuous places along the wharf to promote their own goods. Coastal citizens call this poster a poster. If this development continues, all posters with similar purposes and other information will be called "posters" in the future.

I hope it helps you.
