Li Bai is good at chanting, Yuefu and quatrains, but not at metrical poetry. Because Li Bai is naturally bold and unconstrained, he naturally doesn't like metrical poems that are too bound. He even laughed at Du Fu, who was good at metrical poetry, and said, "Don't be too thin to ask questions, just write poems for the past." He despised the creative way of "singing a sentence and cutting off a few stems" because Li Bai's talent was unrestrained and unrestrained. Writing poetry is a natural expression of life for him. The sentence patterns and rules of Yuefu and Gexing are not very strict, which is suitable for Li Bai to exert his talents.
Because Li Bai doesn't pay much attention to words and sentences, his poems are sometimes "slippery", and even three sentences are inseparable from the flooding images of "bright moon", "white clouds" and "flowing water", and his poems are sometimes too straightforward. But on the whole, the artistic value of Li's poems is still very high.
Li Bai is also a rare master in the history of poetry. Du Fu's quatrains are not like appearances, because he wrote quatrains as a method of metrical poetry, which is not authentic. Wang Changling, the poet's son of heaven, is a master of seven-character quatrains, but his five-character quatrains are inferior. What quatrains require is natural and meaningful, with thousands of miles of interest in hand.
You appreciate sentimental poems, and Du Fu's poems suit you. Li Shangyin's metrical poems are based on Du Fu's and are unique. It's just that sometimes it's really hazy and confusing. I only know that this is a poem, and it is a good poem. I know it is beautiful, but I don't know what it is.
