When was the couplet posted?

As the saying goes: "Twenty-eight, applique", some local folk songs also have the saying "Twenty-nine, paste the couplet (meaning paste the Spring Festival couplets)", so couplets are usually posted on the twenty-eighth and twenty-ninth of the twelfth lunar month. There is also a saying that Spring Festival couplets are posted on the morning of New Year's Eve.

The contents of Spring Festival couplets express people's good wishes for the new year. After the Spring Festival couplets were posted, it became a fire. It is said that it is to drive away Nian beast and bring good luck to the new year? . Nowadays, most people are not very particular about it, and the time for posting couplets is becoming more and more casual. In fact, as long as it means auspiciousness, it is ok to paste Spring Festival couplets.

In mythology, Nian is a fierce beast that comes out to make waves on the last day of the twelfth lunar month.

There are two weaknesses in 2008: fear of red and fear of sound.

So people put red paper on doors and windows and set off firecrackers on the day when Nian beast came out, so as to scare Nian beast away.

Later, couplets, window grilles, fireworks, kicking two feet, 1000 and 500 rings, blooming flowers and falling flowers, drilling monkeys, throwing guns, rowing guns and so on were derived.
