Regarding the posting of Spring Festival couplets, it is necessary to conform to the traditional rules, and the Spring Festival couplets should be posted vertically. The first part should be posted on the right hand side (the left side of the door), the second part should be posted on the left hand side (the right side of the door), and the horizontal batch should also be read from right to left. Upper and lower couplets cannot be posted backwards. For example, "Spring blossoms in full bloom, and China shines in full bloom on warm days" cannot be labeled as "China shines in full bloom on warm days and flowers bloom in spring". From the content point of view, there is a causal relationship between the upper part and the lower part, because "spring blossoms" make everything in China shine in warm days. If you post it backwards, it will reverse the causal relationship and make people feel awkward to read.

Generally speaking, if the suffix is three or four tones, it is the upper part, and if the suffix is one or two tones, it is the lower part. There are also some couplets whose endings are flat, while the endings of the next couplet are ambiguous. Don't think that lisping is the first part.

Because there are two kinds of confrontation: Rightists and Rightists. Here, according to the time when the face is facing the door, it's about. The difference between the upper couplet and the lower couplet: the last word is the upper couplet, which generally refers to three or four tones, such as "Happy New Year to Qing Yu"; The last flat word is the bottom couplet, which is usually one or two tones, such as "FestivalNo". Changchun ". Couplet paste method: this should start from the position advocated in ancient times. In ancient China, "Left" was the dominant position. So couplets should be on the "left" side. The left side here refers to the position of the couplet when the back is facing the door. If the position of the couplet is taken as the standard, that is, when facing the frontispiece, it is the right side. Here, couplets are the direction. In fact, people are used to writing right first and then left, which means the same thing. From the direction of the book itself, it is from left to right.

Look at the horizontal batch: now many people don't write in the past, and some write from left to right. So we mainly look at the horizontal connection. From the direction facing the gate: if the horizontal couplet is a modern writing from left to right. Couplets are also left-handed and right-handed; If the couplet is written from right to left, it is also written on the right and left.
