What's the difference between modern poetry and ancient poetry?

The difference between ancient poetry and modern poetry in form is the most obvious and fundamental, especially in emphasizing the level and even the writing style.

Paying attention to form, that is, stubbornly believing that writing poetry must be proficient in meter and completed in accordance with the prescribed format, is harmful and does more harm than good. Why modern poetry rises is a topic worthy of our consideration. Modern poetry creation is the mainstream of poetry creation in this era and even in the future, which can be seen from the proportion of poetry published on the Internet and traditional journals. On the other hand, if the mainstream position of ancient poetry is not restricted, I am afraid that the level of modern poetry has already surpassed that of ancient poetry.
