Spring is a failed festival.
In our village, there is a person who writes couplets for others. He is very old and looks like a plane. In ancient times, he was definitely a juren or a scholar, and he was eloquent. Usually, he said the same thing to Confucius, Confucianism and Taoism. In a word, this man's handwriting is very good. Generally, he knows anything red and white in the village. In fact, my own Spring Festival couplets are better than those bought in the market. They should have a taste, feel the breath of humanity and have a strong festive atmosphere. However, what you buy on the street is different. They are completely decorations, and they can't feel anything handed down, such as the smell of pen and ink, only the smell of steel under industrial machinery.
Of course, in modern society, no one will write Spring Festival couplets for the sake of cultural inheritance, so why do you have to do something that money can buy? In addition, modern society is so busy that there is no time to learn calligraphy and ancient couplets, let alone write them yourself. But there are also many literati, or people who are very idle, especially have time and are particularly bored. It is also possible to write "Women Return" when you have nothing to do.
So, if you have time and interest, you can write something interesting yourself. If you don't have the time and won't, don't pretend and buy honestly.
