What is the function of couplets?

1: You can have fun. I said that life and work often make mistakes, and you will live forever. For some couples, you can talk about what's on your mind, but feel bored for a while; 2. It is very important to make some friends, like-minded people and sing together, which can enhance feelings and strengthen knowledge; 3. It can exercise the ability of choosing words and making sentences, increase our literary talent and exercise our imagination and logical thinking ability, which is a very important role of couplets, I think. As for the importance of language and articles, I think everyone understands it, but it is really not easy to say good words and write good articles. However, couplets can help us exercise this to a great extent. No wonder master Chen strongly suggested setting up a "pairing" course in the school classroom. I think the main functions of language and writing are nothing more than: images, scenery, lyricism, ambition, reasoning and so on. Couplets can achieve the above goals in a short time, which puts forward higher requirements for the rhythm, antithesis and artistic conception of words. Now I feel that couplets are the same as playing ball games. The rules of his music antithesis are like all kinds of rules of playing ball. You can't break the rules, but the purpose is also very clear, mainly to reflect the artistic conception, just like playing ball and scoring goals. Under these rules, we thought hard for a long time and finally came up with a result, just like playing ball and scoring goals. Thinking under these couplet rules is like all kinds of sports under the rules of playing ball. Couplets exercise thinking and play ball to exercise. It's true: couplets are played by the brain, while playing is played by the body.
