For Li Yu, as a politician, he is a complete failure, but as a writer, he has been admired by the future generations, as the evaluation of the later generation: "The country is unfortunate, the poet is fortunate, the words to the vicissitudes of the language began to work". What I think about Li Yu is the relationship between politics and literature. Li Yu's lyrics never had the political concept of worrying about the country and the people. He only cared about the beauty of the lyrics themselves, and he would never break the rhyme of the lyrics in order to speak strongly about the national affairs (this is also one of the reasons why I don't like Xin's lyrics), so his lyrics were all beautiful and artistic masterpieces. This idea is "art for art's sake", which should be the highest concept of an artist. Why must literature "carry the Tao"? The history of art is much earlier than that of politics, and human beings have already known how to express their emotions through dance when they were still in a hazy state. To say that art has appeared in the service of politics is sheer sophistry. The role of art should be to express the most sincere emotion in human heart rather than to show the politics which represents the ugliness of human nature. If we want to add a heavy theme to art, this "art" is no longer art, but an ugly tool. If Li Yu's words are full of sadness about the pain of his country's demise or about his inability to compete with the rest of the world, then Li Yu in the history of modern art is just a third-rate patriotic lyricist.
