Why do you post Spring Festival couplets from left to right?

Sticking Spring Festival couplets is from right to left in principle. Sticking Spring Festival couplets is an ancient traditional folk custom in China. Pay attention to being old when posting, that is, "people stand facing the door, with their right hands on the top and their left hands on the bottom". In other words, the first part should be attached to the right hand side and the second part should be attached to the left hand side. Because according to the traditional reading method, straight books are read from right to left, so posting Spring Festival couplets should be from right to left.

In recent years, some changes have taken place in the pasting method of Spring Festival couplets, which mainly comes from the change of the traditional Chinese character writing order from right to left. Therefore, the pasting method of Spring Festival couplets has also changed, but this change is not random, mainly depending on the writing order of horizontal batches. If the horizontal batch is written from right to left according to the traditional writing method, the upper part is attached to the right side and the lower part is attached to the left side; If the horizontal batch of characters is arranged from left to right, the upper part can be left, the lower part can be right, the upper part can be right and the lower part can be left, so the sense of disobedience is not strong.

Distinguish the upper and lower couplets of Spring Festival couplets: Spring Festival couplets are divided into upper and lower couplets, which are distinguished by the pronunciation of the last word, and the last word of couplets is the third and fourth tone; The last word in the bottom couplet is Pingsheng, which is the first sound and the second sound respectively.
