What is the difference between a poet and a musician?

In ancient times, a poem was a song and a song was a poem. That's why a poem is also called poetry. After the Tang Dynasty, the poem was moved to the literary world, and there are certain stereotypes, such as five lines of poetry, seven lines of poetry, the ancient entertainment facilities are poor, the government also encourages folk poetry, painting, cuju and other activities, to put it bluntly is to be able to play a stabilizing society, to divert the attention of the public, and even as a way to divide the class. For example, the emergence of what a great man of letters, a family of books, in that kind of deformed era, you are the inventor of no good, will mouth to two sentences, you are a great man of letters, the wind flow of talent, so the ancient invention of the waterwheel, the invention of the brick, the invention of the oxcart of the people are not famous, and no good, Li Bai, these people will be passed down to the ancient times. What's the difference between the song and the current one? It's not as good as a song, after all, it's just a song without a tune. Just like now, poetry, painting, fishing, chess, square dancing, singing is just like that, to cultivate the sentiment. Just like the first few years of soccer and basketball, as long as the country is willing to publicize, there are many people will go after. But these are really not as good as scientists, not as good as researchers, not as good as technical workers, but our long-term rigid thinking always think they are the most important, but the last three are not important.
