Poetry before the Tang Dynasty grew up, Tang poetry was shouted out, Song poetry was invented and Song poetry was imitated. How to understand it?

Poems before the Tang Dynasty, such as the Book of Songs and Yuefu, all happened. People sing them into poems because they have prototypes and vitality. Therefore, the long Tang poems especially worship these bold poets, and their words are magnificent. Therefore, it is called Song Poetry, which is more pragmatic and has certain philosophies and allusions. Therefore, there are basically no good poems after the Song Dynasty, and they are basically modeled after the ancients.
