In Engpsh, we say "hang up a Spring Festival couplet" to describe the act of posting Spring Festival couplets on one's home. Spring Festival couplets are traditional Chinese decorations that consist of a pair of horizontal red scrolls with gold or black characters written on them. They are usually displayed on either side of a door or gate during the Chinese New Year to bring good luck and prosperity. Here is an example sentence: "We are getting ready for the Chinese New Year by hanging up our Spring Festival couplets at home."
