Li Bai's poetry and song style has gone through several stages.

Li Bai's poems have their own characteristics and varied styles, so it is difficult to sum up their styles in different periods with the word "elegance". Before and after Li Bai left Sichuan, he was deeply influenced by Taoist thought, and his poetry was characterized by elegance. He was depressed when he entered Chang 'an, but he didn't lose hope. His poetic style is bold and unrestrained, and his feelings are passionate. He sang repeatedly that he was very talented and useful. After Li Bai entered Chang 'an, his career was bumpy, his state affairs declined day by day, his life was in a desperate situation, his poetic style was close to reality step by step, and his boldness was full of melancholy for the country and the people. When Yelang was exiled in his later years, Li Baiduo expressed his feelings, exposed reality and lashed the society in a gloomy, resentful and sad style, and his poetic style obviously turned to tragedy.
