How to divide the left and right sides of pasted couplets

The method of pasting couplets to distinguish the left and right sides is as follows:

Couplets have already had a conventional habit, that is, the word at the end of the first couplet should use a oblique tone, which is equivalent to the three words in modern Chinese. Tone or four tones, the ending character of the second line is usually Ping tones, which is equivalent to the first or second tones in modern Chinese. From a phonological point of view, it sounds pleasant and pleasant to the ears when read like this. This method can also be used to check whether the Spring Festival couplets are hanging correctly.

The order of upper and lower couplets: When posting Spring Festival couplets, the order is the most important. Many couplets have a cause-and-effect relationship between the upper and lower lines. If they are read incorrectly, it will not make sense, and if they are posted incorrectly, they will make a joke. Nowadays, the Spring Festival couplets affixed to the main door are generally called door couplets, and those affixed to the inner door (second door) are called double-door couplets. Many families now have anti-theft doors installed. At this time, you can just hang the upper and lower couplets on the anti-theft door. If they are posted on the surrounding walls, they will not look neat enough.

First of all, it depends on the writing of the horizontal batch. If the horizontal batch is written from right to left, the top couplet should be pasted on the right, otherwise the top couplet should be pasted on the left. In addition, in addition to the requirements for antithesis and other requirements, couplets should generally have upper and lower tones, that is, the pitch of the last word of the first couplet should fall on the rising and falling tones, and the pitch of the last word of the second couplet should fall on the flat tone.

The position of the upper and lower couplets: According to the reading method of ancient books, the upper couplet is on the right and the second couplet is on the left. Nowadays, there are many pairs on doors and columns, and many of them are pasted upside down. Often, the top couplet is pasted on the left and the bottom couplet is pasted on the right. Sometimes, it is not easy to detect when pasting it backwards, because for some couplets, which couplet is read first has little impact on the meaning, but most of them do not. For example, "Spring silkworms will not run out of silk until they die, and wax torches will not dry until they turn to ashes and shed tears."
