So some people think that the later products are modified and optimized on the original basis. Just like our electronic products, the second generation always corrects its shortcomings and further optimizes its functions on the basis of the first generation.
But there is a difference between electronic products and poetry. There are many metrical poems in the late Northern and Southern Dynasties, which can only explain one problem. The rise of metrical poetry is late, but it is highly accepted by later generations, but it does not mean that metrical poetry is more advanced than classical poetry.
After all, it is unscientific to measure only by quantity. Moreover, in the late Northern and Southern Dynasties, metrical poems often lost their attachment and violated the law. However, because more poets pay more attention to smoothness and smoothness, they are more accustomed to using metrical poems and pay more attention to the so-called "poetic disease".
Everyone will have their own understanding of the same thing. So did the ancients in China. Song people think that Tang poetry is better, and Tang people think that Wei and Jin dynasties are better.
People have different views on things like culture. It can't be measured by a higher level, which is one-sided.
Moreover, in chronological order, metrical poems appeared relatively late. However, after the appearance of metrical poetry, there are still poets who create with classical poetry, and classical poetry has not disappeared.
Just like we are all using vernacular Chinese today, we can't say that vernacular Chinese is superior to classical Chinese, which is the product of a certain stage and cannot be compared horizontally.
