For example, in early classical poetry, there was really no rhyme, no prescribed number of lines, and the number of words per line was relatively random, regardless of the length of a poem.
In the middle period, ancient poetry began to rhyme and had certain norms.
In the late period of ancient style, there was a rhyme format of seven words and five words, which was very close to metrical poetry.
It can be found that early classical poetry is very close to the format and rules of modern poetry, and it is a free genre.
In the middle period, poems like Xu Zhimo have certain norms, but they are not very strict. They just want rhyme and overall neatness.
At the beginning, modern poetry was based on ancient poetry. It can be said that modern poetry is a clone and re-creation of ancient poetry, and the techniques of ancient poetry have also been well used in modern poetry.
Antique and modern poetry come down in one continuous line, but modern poetry uses modern Chinese, and its expression content is more modern.
Therefore, modern poetry does not come out of thin air, but inherits ancient poetry.
