according to the level of the couplets, the festive season goes smoothly every year, and the final pronunciation is level. The final pronunciation of the red for welcoming the new year is flat, and the couplets are linked at the bottom right and left, so the festive season goes smoothly every year, welcoming the new year and opening the door to the left.
Because the ancient people's reading and writing habits were from right to left, couplets were also from right to left. The right is the upper part and the left is the lower part.
