How to paste the door couplet?

If the horizontal batch is read from left to right, then "Smooth sailing, rich financial resources" will be posted on the left and "Peace and happiness in the four seasons" will be posted on the right. If you read from right to left, the situation is just the opposite. Couplets are divided into upper and lower couplets, and there are horizontal batches. Be careful when posting, don't post backwards, or you will make a joke. (1) When posting, look at the horizontal batch first. If the horizontal batch is viewed from left to right. Then on the left is the upper part. If you read from right to left, the upper part is on the right. Traditionally, the right side is the upper part and the left side is the lower part. (2) Next, we should distinguish the upper and lower couplets, which can be distinguished according to the content. The key is to look at the last word of the left and right couplets. If it is silent, it is the upper part, but it is the lower part. Of course, we need to combine the contents of couplets. Generally, couplets are required to be flat! (3) In this way, we have determined the up and down links, and then determined the posting direction. When pasting, first paste the horizontal batch on the door, and then paste it on the left and right sides. Of course, if you have a good idea, no matter which one you send first, you can't go wrong! Just pay attention to the proportion symmetry. In addition, the size of couplets should be coordinated with their own portals. It is best to stick couplets with a width of 15 to 20 cm in front of residents' houses, and it is best to stick couplets with a width of 20 to 30 cm in front of merchants' shops, which is harmonious and generous. As for the gates of some tall buildings, if couplets are posted, the width of the couplets should not exceed 40 cm.
