Couplets are divided into upper and lower couplets, and cannot be pasted wrong. In ancient times, couplets were written from right to left, so the couplet was on the right side of the door. Now, due to the habit of writing from left to right, some people stick the top couplets on the left side of the door. The words at the end of couplets should be inarticulate. The three or four tones in modern Chinese give people the impression that the words are not finished. The words at the end of the couplet should be flat tones, one or two sounds in modern Chinese. The flat tones give people the impression that the words have been written.
