1: It can be used for entertainment and recreation. As I said, there are often difficulties in life and work, and there are twists and turns in life. With these couples, you can talk to relieve your worries and temporarily relieve your boredom; 2: You can get to know some people. Friends, everyone has the same goals and sings to each other, which can enhance feelings and enhance knowledge. This is a very important point; 3. It can exercise the ability to choose words and make sentences, increase our literary talent, and exercise our imagination and logical thinking ability. This is Couplets play a very important role, I think. As for the importance of language and articles, I think everyone understands it, but how to speak well and write good articles is indeed not easy. But couplets can help us practice this to a great extent. No wonder the great master Chen Yinke strongly recommended that schools offer courses on "pairs". I think the main functions of language and writing are nothing more than describing objects, describing scenes, expressing emotions, expressing aspirations, reasoning, etc. Couplets can achieve the above-mentioned purposes even in short numbers, and they put forward higher requirements on the pronunciation, contrast, and artistic conception of the text. I now feel that playing couplets is like playing basketball to exercise. The rules of his rhythmic battles are like the various rules of playing. No fouls are allowed, but the purpose is also very clear. It mainly reflects the artistic conception, just like playing to score goals. Same. We thought hard and long under these rules, and finally came up with a result, just like scoring a goal in a ball game. Thinking under these couplet rules is like playing various sports under the rules of playing ball. Couplets exercise the mind, and playing ball exercises the body. It’s true: the couplet is the brain playing the ball, and playing the ball is the body playing the couplet.
