One way to hold it: an organization has a front door. Inside, people make things and make decisions. Outside stand customers, neighbours, reporters, everyone else. Public relations lives at that door — sometimes it names the work of standing there and explaining what goes on inside, and sometimes it names the state of the relationship across that doorway.
From the word’s history
The phrase dates from the early twentieth century, and Wiktionary notes it spread as a neutral replacement for propaganda once that word turned negative — which fits the door image: the same explaining work, renamed as a relationship rather than a message pushed out.
根據 Wiktionary，這個說法出現在二十世紀初，並且是在 propaganda（宣傳）變得負面之後，被當成中性的替代說法而流行起來。這條線索剛好對上門口的畫面：同樣是向外說明，但重點被改寫成「關係」，而不是單向推出去的訊息。
