Question re. CNY decoration tiles with characters on it

I guess we have all seen the square tiles with Chinese characters on it that are put up as decoration for CNY, typically a red color paper with black or gold writing on it (one character only per tile). I noticed that sometimes the thing is up-side-down, in particular the 春 (chūn) character. There even is a commercial on TV where it’s hung on the front door and then the “dad” flips up-side-down.

Anybody knows what’s up with that?

The characters you usually see upside-down are 春 (spring) and 福 (good fortune). The word 倒 (dao4), meaning to “turn upside down” sounds like the word 到 (dao4), meaning “to arrive”, “to be present”.

So the implied meaning is “Spring is here! Good fortune is here!”

Thanks! One mystery solved.

They’re called spring couplets.

Not if they have one character.

I suppose not.Would they simply be called tiles,then?
