What are the ancient books about growth?

Now people generally agree that the "Yuefu" was first registered as a "trademark" in the Qin Dynasty, and then after the country's demise, Emperor Wu of the Han Dynasty felt that this institution was not bad, so he created the "Yuefu", which is what our history books said that the Han Dynasty inherited the Qin system; From this point of view, Yuefu here in Han Dynasty is the inheritance and development of Yuefu, which not only completely retains the name of Yuefu, but also expands its scale on the basis of Qin Dynasty. Here, we have to mention a modern science-archaeology. It is precisely because of the continuous development of archaeology that we can now be said to be the Yuefu that existed in the Qin Dynasty. As mentioned earlier, everyone in Li Qin School uses ancient books as evidence. Then, after 1976, when we took out the ancient clock engraved with the word "Yuefu" from the first imperial tomb, everyone in Han Li School was obviously going to cry. Another archaeological relic that further affirmed the historical facts of Yuefu in Qin Dynasty was in the last year of the 20th century, as if the puzzle had been solved earlier in the old century. In the site of Xi 'an Qin Dynasty, we once again unearthed a piece of cultural relics evidence about the establishment of Yuefu, so in the new century, it can be clearly concluded that Yuefu began in the Qin Dynasty rather than the period of Emperor Wu of Han Dynasty. Unless there is more convincing evidence in our archaeological discoveries in the future, this debate will continue.

In the contemporary "Yuefu Poems", many people didn't have copyright awareness when they collected them at that time. We often find many good poems, but we don't know their real authors, so we collect them in Yuefu, a huge institution. Later, the world called their collected poems Yuefu poems, also known as Yuefu poems. Moreover, because our ancestors like to spread the excellent culture of their ancestors, when the wheel of history rolled to the Tang Dynasty, a dynasty with highly prosperous poetry and extremely developed political economy, they developed a new way of playing. These poems, whose "tunes" have been forgotten by history, have been chosen as templates for literary creation among scholars and poets. Moreover, the "fun-loving and eager to learn" Tang people have also played new tricks, and all major writers and poets are scrambling to "develop" them to express their feelings, such as "Sai Shang Qu" and "Guan Shanyue", and there are poets who go out with three or two friends to record their lives with Yuefu themes. These poems are sought after because they don't have the strict rhythm requirements of other metrical poems, and the ancient poems with Yuefu theme imitated in the Tang Dynasty are also a bright pearl in the Tang Dynasty ~
