Banners were hung on the north gate years ago, and the word "Fu" was posted on the New Year. Is this a good way to paste Feng Shui? Is there a problem? Is it taboo to take off after the age of fifteen?

Sticking couplets is a custom to celebrate the Spring Festival, which means family reunion. It is necessary to stick couplets during the Spring Festival. After the Spring Festival couplets are posted, the Spring Festival can only be posted in the second year. New couplets can be torn off when they are posted, but not at other times. This is a traditional custom.

I don't know why I want to post banners, as long as it doesn't affect the posting of couplets.
