You need to see how much this is. In fact, there is no sure way to make money in business, and making money depends on methods. From the perspective of selling couplets, you will definitely earn more money than usual during the New Year. But from the point of view of buying and selling, you can earn a few dollars by selling the right one.

If you like doing it, this matter can be considered from the following aspects. The first is why people buy your pair. In other words, you two must have their own characteristics. Either your handwriting is good, or your pair is good, or if you become famous, someone will buy your pair. Secondly, if you don't have that word, that literary talent and that fame, you have to honestly find a printing factory to cooperate, collect the right materials extensively, and then negotiate with suppliers to make sales. Thirdly, if you can't supply it, you have to be a second-hand dealer and buy the printed couplets to sell. Personally, I think this is the most unreliable and unprofitable scheme.
