The upper and lower couplets of couplets can be distinguished by the chronological order of the couplets and the tone of the characters. The Spring Festival couplets are pasted in the same way as in ancient times, because the horizontal scrolls were written from right to left in ancient times, so when pasting couplets, the upper couplet should be pasted on the right side, and the lower couplet should be pasted on the left side, which has lasted from ancient times to the present.
