Li Bai, a great poet, can best embody the spirit of the prosperous Tang Dynasty and represent the high artistic achievements of poetry in the prosperous Tang Dynasty. Li Bai is a poet with heroic personality, unrestrained feelings, boldness and eagerness to make contributions. His poems fully show the self-confidence and ambition of the literati in the prosperous Tang Dynasty, and are full of ideals. His achievements in poetry are various, which greatly enriched the expression of classical poetry and pushed the creation of Yuefu poetry to a new height. His seven-character quatrains, together with Wang Changling's seven-character quatrains, were later praised as the representative works of the Tang Dynasty. His poems have distinct artistic personality: explosive lyricism, unpredictable imagination and vivid images. He writes Yuefu and songs like flowing water, and his feelings gush out, just like the water of the Yellow River, flowing thousands of miles and pouring down. Born in the prosperous Tang Dynasty, I felt the high spirit of the times in the prosperous Tang Dynasty. In his later years, he witnessed the decline of Tang society, and the contrast between ideal and reality was huge. In his poems, there are both confidence in establishing meritorious deeds and indignation and criticism of the darkness of the imperial court. He once went to Beijing to worship the Hanlin, and was appreciated by Emperor Xuanzong of the Tang Dynasty. He felt that it was time to make contributions and be elated. Not long after, he was slandered by the powerful minister and expelled from the court, only then did he realize that state affairs were actually corrupt. He said that he is "a poem in the north window, a million words are not worth a glass of water", and he is brilliant and cannot be reused; While denouncing those mediocre people who are proud of the spring breeze, "Huayi Boxing can't be eaten as a meal, and donkeys are proud of the spring breeze", they directly denounce those traitors "Dong Long is a chicken and dog!" Even in the case of frustration, he did not forget to serve his country. After the Anshi Rebellion, he joined the army twice. His poems are so imaginative that he often thinks that people think everywhere. Previous people commented on his poems, saying that "out of nothing", "difficult to get around" and "dreaming of climbing Mount Tianmu" are all examples. In my imagination, I often use exaggerated elements to write that I am worried about having white hair, saying that it is "white hair and three thousands of feet"; Write the five old peaks of Lushan Mountain, saying, "Jin Furong cut out the sky"; Write about the Yellow River, saying that "the Yellow River falls into the East China Sea and Wan Li falls into the bosom". He is an imaginative poet, and his poems are often strongly subjective. Because of his cheerful and bold personality, his poems are bright, fresh and colorful. He is a gifted poet.
