Confucius once said: "If you don't learn poetry, you won't be able to express it." Literally speaking, it should be that if you don’t read the Book of Songs, you won’t be able to speak. Let's analyze the composition of "The Book of Songs": "The Book of Songs" is divided into "Guofeng", "Da and Xiaoya", and "Songs of Zhou and Lu". National style should be folk songs. Compared with official songs, folk songs are so-called popular songs. Da and Xiaoya are formal songs for gatherings of scholar-bureaucrats, equivalent to "classic music" or serious dramas. Songs, that is, Officially prescribed songs, such as the national anthem ("March of the Volunteers"), quasi-national anthem ("The East Is Red", "The Sea Sails Depends on the Helmsman" during the Cultural Revolution, and now "Singing the Motherland"). We know that poetry is the essence of language. "If you don't learn poetry, you won't be able to speak." It should mean that if you don't learn the essence of language, you won't be able to speak vividly and accurately. So, in the time of Confucius, "The Book of Songs" should be the "collection of popular songs and classic songs" at that time. Therefore, by learning poetry, you can make your language more vivid, beautiful, and accurate. So where are we now? Do you still read the Book of Songs now? As times change, so do "popular songs." During the Warring States Period, "Chu Ci" became popular in the south. By the Han Dynasty, four-character poems were gradually replaced by five-character poems and seven-character poems and became more popular. This form of poetry is in line with Chinese people's language habits, so the lyrics of popular songs are full of five characters and seven characters. From the "vulgarity" of Han people's five or seven character poems to the "elegance" of Tang poetry. Tang poetry has become a glorious and unparalleled pinnacle in the Chinese poetry world. Then long and short sentences became popular, from the "Shiyu" of the Song Dynasty to the "Quqi Ci" of the Yuan Dynasty. After moving from the unified "five or seven words" to "long and short sentences", it gradually moved towards secularization. By the way, secularization is where poetry begins. Wind is folk songs and pop songs. Therefore, it is popular and vulgar and vulgar is inevitable and unavoidable. However, under the influence of people's increasing pursuit of perfection, "elegance" came into being. It should be said that "elegance" is the product of people's self-improvement. This is true in the world of poetry, and why is it not the same in the world of words and deeds? Therefore, here seems to be a problem of the transformation of vulgar culture into elegant culture. It turns out that the star-chasers are just "learning poetry"! Although they are learning too superficially, they are learning after all. However, it is not enough to have a little "wind". You should also learn a little "elegance", a little "Chu Ci" in "The Book of Songs", and a little Tang poetry, Song lyrics, Yuan music, Ming and Qing couplets. They should go from being eloquent to being good at speaking; from being vulgar to being elegant. What our schools should do, isn’t it to provide correct guidance? That is to guide young people’s passion for chasing stars into improving their spiritual realm, allowing them to start with poetry and end with etiquette. That is to say, let them start by chasing stars, and gradually improve their cultural taste, so that their words and deeds become elegant and more like gentlemen and ladies. Of course it's not good if you can't speak, but it's not necessarily good if you just say rude words. To study poetry is to start from the vulgar "wind", gradually learn the "elegance", and finally be able to act according to the "propriety" and reach the state of "joy". Perhaps this understanding can be close to the original meaning of Confucius' "If you don't learn poetry, you will have no words."
