China's early classical poems include The Book of Songs and Songs of the South. However, since the Five Dynasties and Ten Kingdoms period, a relatively novel form has appeared in China's literary world, which is modern poetry different from early ancient poetry. Generally speaking, a considerable part of Tang poetry belongs to this kind of poetry. It mainly includes metrical poems and quatrains, and pays attention to strict metrical rules, which should not only rhyme, but also be implicit and artistic. Of course, China's generalized classical poetry also includes "Ci" and "Qu", and he also pays great attention to epigraph, meter and rhyme.
Foreign poetry also originates from life and reproduces life. However, compared with China's classical poetry, foreign poetry is more free and unrestrained. Due to different cultural backgrounds, it is difficult for us to appreciate the beauty of many foreign poems without reading the original works.
China's classical poetry has obviously declined in the last 100 years. Some people think that it is rigid in form, which imprisons thoughts and fetters thinking and creation. This is not completely unreasonable. Therefore, new poetry (free verse) quickly became popular. China's modern poetry has absorbed a lot of nutrition from foreign poetry, and the "convergence" between them makes the difference little.
Poetic quatrains that appeared after the Tang Dynasty in China pay attention to meter, such as the number of sentences, the number of words, the level of words, rhyme and so on. The rules are strict. China's poems are subtle, concise and pay attention to artistic conception. Foreign poetry is not as exquisite as China's classical poetry, but more free and unrestrained. There is not much difference between China's modern poetry (free verse) and foreign poetry.
