Why can't paper book shops post couplets such as making a fortune during the Spring Festival?

Taboo 1: Don't paste the left and right couplets wrong. When posting Spring Festival couplets, some people often misplace the upper and lower couplets. The key to distinguish between up and down is the last word. According to the rules, the last word in the upper part must end in a light tone (three or four tones in Mandarin) and the lower part in a flat tone (one or two tones in Mandarin). 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: the time to post Spring Festival couplets. 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.

Taboo 3: Odd numbers are auspicious. Post Spring Festival couplets at the gate, remember to post odd numbers to symbolize good luck. Also, don't just post the word "Spring" on your doorstep, you can post blessings, make money and treasure, because in ancient times, only Yee Justin would post the word "Spring" on your doorstep.

Taboo 4: The word "Fu" can't be posted casually. When posting Spring Festival couplets, some people still like to post the word "Fu", but not all of them have to be posted backwards.

1, the word "fu" on the gate must be posted. The word "Fu" on the gate means "Welcome to Fu" and "Accept Fu". The gate is the entrance and exit of the family and a solemn place. The word "fu" posted must be solemn and generous, so it must be posted correctly.

2. The word "Fu" on the cabinet should be pasted backwards. A cupboard is a place to store things. The word "fu" is pasted backwards, which means that the good news (and wealth) will always come to the home, the house and the cupboard.
