Can't I post couplets for the New Year? Why?

According to different local customs, the time for posting Spring Festival couplets is slightly different. As the saying goes, "Twenty-eight, applique", in some local folk songs, there is also the saying "Twenty-nine, paste the Spring Festival couplets upside down". Spring Festival couplets are usually posted on the 28th and 29th of the twelfth lunar month, but most people are not very particular about it.

Burning: There is also the saying of "burning Spring Festival couplets", which means burning the old ones, which means burning all the bad luck.
