What is the traditional festival of posting Spring Festival couplets? When will the Spring Festival couplets be posted?

1. In China, every household should choose a pair of red Spring Festival couplets every Spring Festival, whether in urban or rural areas, and stick a blessing on the door to add a festive atmosphere to the Spring Festival. Therefore, it is essential to prepare Spring Festival couplets and blessings before the New Year.

2. It is said that the custom of pasting Spring Festival couplets before the New Year in China began in Shu about 1000 years ago, which is proved by history. The original form of Spring Festival couplets is what people call "Taofu".

3. In ancient myths and legends of China, it is said that there is a ghost world, in which there is a mountain, a big peach tree covering 3000 miles, and a golden rooster on the treetop. Whenever the golden rooster crows in the morning, the ghost who travels at night must rush back to the ghost domain.

4. The Gate of the Ghost Domain is located in the northeast of the peach tree. There are two gods standing by the door, named Shen Tu and Lei Yu. If the ghost does something unnatural at night, Shen Tu and Lei Yu will immediately find it, catch it, tie it up with a rope made of Miscanthus and give it to the tiger. So all the ghosts in the world are afraid of Shen Tu and Lei Yu. So people carved them into peach trees and put them at their doorsteps to ward off evil spirits and prevent harm.

5. Later, people simply carved the names of Shen Tu and Lei Yu on the mahogany board, thinking that this could also eliminate disasters. This kind of red board was later called "Fu Tao".
