Li Bai, the word Taibai, was a great romantic poet in Tang Dynasty. He was praised as "Poet Fairy" by later generations, and was also called "Du Li" with Du Fu. In order to distinguish them from the other two poets, Li Shangyin and Du Mu, that is, "Little Du Li", Du Fu and Li Bai are also called "Big Du Li". According to the Book of the New Tang Dynasty, Li Bai is the grandson of Sheng Xing IX and belongs to the same clan as the kings of Li Tang. He is cheerful and generous, loves to drink and write poems, and likes to make friends. He was deeply influenced by Huang Lao's idea of sorting out villages, such as Li Taibai Ji, which was handed down from generation to generation, and most of his poems were written when he was drunk. His representative works include Looking at Lushan Waterfall, it is hard to go, Difficult Road to Shu, Entering Wine, Liang, The First Full City, etc.

Li Bai's poems are magnificent and elegant, and his artistic achievements are extremely high. He eulogized the mountains and rivers and beautiful natural scenery of the motherland, with bold and unrestrained style, elegant and fresh, full of romantic spirit, achieving the unity of content and art, completely breaking all the inherent forms of poetry creation, ethereal and changeable, and reaching the magical realm of unpredictability and swaying. Its quatrains are more natural and lively, elegant and unique, and can express endless feelings in concise and lively language. Among the poets in the prosperous Tang Dynasty, Wang Wei and Meng Haoran were good at the Five Wonders, while Wang Changling and others wrote the Seven Wonders well. Li Bai is the only one who is good at both the Five Odds and the Seven Odds.

In Li Bai's poems, imagination, exaggeration, metaphor, personification and other techniques are often used comprehensively to produce magical brilliance and magnificent artistic conception, which is the reason why Li Bai's romantic poems give people heroic and unrestrained, elegant and immortal. It is said that he and several literati often get together to drink and sing, and He, a poet in the Tang Dynasty, is one of them. He appreciates Li Bai's poems. It is said that when he saw Li Bai's Difficult Shu Dao, he called it "fallen immortal" with great admiration and compared him to a "fairy" who fell from the sky. Therefore, later generations called Li Bai "the Poet Fairy".

There are two main reasons for calling Li Bai a poet: first, his romantic poetic style and bold personality are extraordinary; Second, He Zhangzhi praised his poems, calling Li Bai "fallen immortal", and later called him "poetic immortal".
