The order of reading couplets is determined by the horizontal batch. If the horizontal batch is read from right to left, then the couplet should also be read from right. If the horizontal batch is read from left to right, then the couplet is also read from left. According to the traditional custom, it is necessary to distinguish the upper and lower heads of the door. When facing the gate, the right hand side is the head and the left hand direction is the hand. When pasting couplets, the first couplet is attached, and the second couplet is attached.
Sticking method of couplets
The traditional method of pasting couplets is that the upper couplet is on the right and the lower couplet is on the left. This is actually related to the ancient writing habit from right to left. Of course, horizontal batch is the same, writing from right to left and reading from right to left.
However, after the development of the times, the pasting method from left to right began to appear. Now writing from left to right, horizontal criticism is also common. So it's always confusing. Yu Lanjun believes that since couplets are "traditional culture", it is better to read them from right to left like calligraphy. There is no need to pursue its "significance of the times".
