Taboo 1: Left and right stickers are wrong
When posting Spring Festival couplets, some people often misplace the upper and lower couplets. The key to distinguish the upper and lower couplets lies in the last word. According to the rules, the last word of the first couplet must end in a soft voice, and the second couplet must end in a flat voice.
When pasting couplets, the upper couplet is pasted on the right, the lower couplet is pasted on the left, and the left and right are bounded by the gate or pilaster. The reason for posting this way is that the straight writing is from right to left, so reading couplets is also from right to left.
Taboo 2: Sticking Spring Festival couplets regardless of time.
There is a folk myth that Spring Festival couplets are immortals in the sky. When the Spring Festival couplets are torn, they will report to the Jade Emperor the situation of each household, hoping that the gods can bring good luck to the folk families.
It is best to stick Spring Festival couplets between 6 am and noon 12 on New Year's Eve, tearing up the old ones, which means breaking bad luck and tearing up the old ones.
