First of all, according to the geographical points, take China's poems and western poems as examples. Western poetry includes sonnets with neat format, free poems with informal format, long historical poems and long religious poems, such as Homer's epic and Dante's Divine Comedy, as well as poems expressing feelings, such as Pushkin's Bronze Knight. Western poetry mainly relies on metaphor to achieve singing and popularity.
China's ancient poems, from The Book of Songs to Yuefu in Han Dynasty, were mainly folk songs, and then evolved into metrical poems and ci poems after the Southern and Northern Dynasties. Some of them are more rigorous, paying attention to antithesis and leveling, while others, such as Li Bai's poems and songs, pay attention to lyricism rather than meter.
China's modern poems, such as Xu Zhimo's, which are close to the west, look beautiful and full of aesthetic feeling.
Modern poetry, mostly moaning without illness, is difficult to spread to future generations. If you are interested in modern poetry, you can refer to Tagore, Shelley, Xu Zhimo, Guo Moruo and other modern poems with high achievements.
