Couplet pasting method:
1. Old-fashioned Spring Couplet pasting method: The most orthodox method is to face the door, paste the top couplet on the right side of the door frame, and paste the bottom couplet on the left side of the door frame. This is the old-fashioned method of pasting Spring Festival couplets, which is in line with the ancient people's running script from right to left.
2. The current mainstream method of pasting Spring Festival couplets: Paste the upper couplet on the left side of the door, and the second couplet on the right side of the door. This is the new style of Spring Festival couplets, which conforms to the writing characteristics of modern people. Facing the door, from left to right.
To sum up, should the first couplet of Spring Festival couplets be posted on the left or the right? The most correct way is to observe the direction of the horizontal batch. If the horizontal batch is read from left to right, we default to the left side as the top, and paste the first couplet on the left, and vice versa.
