It is more common to write congratulations vertically, saying congratulations at the top right, autographing at the bottom left, which is a slogan, and writing the date of congratulations vertically on the left. There are no punctuation marks in the writing of couplets. The arrangement of couplets is that the upper couplet is hung on the right and the lower couplet is hung on the left (if there is a banner, it is hung horizontally on the upper edge between the two couplets). )
The language of Xi and He Lian is very refined and general. A few words to a dozen words should express a lot of congratulations, and the words are beautiful and neat.
