The winter vacation is about to begin. In order to create the atmosphere of the Spring Festival, the school sent Spring Festival couplets to every dormitory in the university, so that everyone could stick them at the door of their dormitory. But here's the problem. Seeing these words, we were all deceived. Some of us don't know how to read them. What's the point of posting Spring Festival couplets? I don't know how to distinguish the upper part from the lower part. Is this the right way to post it?

The last word of the couplet is a hyphen (three tones, four tones), and the straight word is a hyphen, which is the couplet.

The last word of the next couplet is a flat tone (one tone and two tones), and the sweet word is a flat tone, which is the next couplet.

Where the couplets are posted, the right hand side of the couplets is posted, and the left hand side is posted.
