Note: First of all, the number of words in Spring Festival couplets should be equal, which is the most basic rule. Then, the words of the upper and lower couplets should correspond. Then, the upper and lower lines should be coordinated. Traditionally, the upper part should be silent and the lower part should be flat. Traditionally, Spring Festival couplets are written vertically from top to bottom, with the upper couplet attached to the right hand side and the lower couplet attached to the left hand side.
In addition, horizontal batch processing is traditionally read from right to left. But now the Spring Festival couplets have a new way of pasting, the first one is pasted on the left, and the second one is pasted on the right. This is also possible, but it should be noted that the horizontal batch will be read from left to right at this time.
Extended data:
Distinguishing the horizontal tone is the most basic method, but it is also the safest. Apart from the confusion of ancient and modern sounds, some couplets are not even, but such couplets are rare. For example, Yuelu Academy in Changsha, Hunan Province has a famous couplet: Chu Youcai, Yu Siwei, is a beautiful couplet that breaks the level, and is equally harmonious, cadenced and neat.
This couplet is an inheritance relationship, which is opposite, so when we distinguish couplets from couplets, we can compare their inheritance relationship and internal relations. If there is a chronological order, the first one is usually above, and the last one is below.
Also, you can find a match. If there are words in the same position in the upper and lower couplets that can be juxtaposed into one word, the first word in this collocated word is the upper couplet and the second word is the lower couplet.
