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 entering Chang 'an, Li Bai's career was bumpy, his state affairs were declining, and his life was in dire straits. His poetic style is approaching the reality of the window of Jinzhong step by step, and his boldness is 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.
Du Fu's poetic style was formed in the period of An Shi Rebellion, and gradually took shape in suffering. Du Fu went deep into the society, cared about the sufferings of politics and people's livelihood, and attached importance to realism. As the window of Jinzhong, he shoulders the heavy responsibility of the country and the nation and faithfully depicts the face of the times and inner feelings. Du Fu's artistic style is gloomy and frustrated. Du Fu's realistic style was inherited from the Middle Tang Dynasty to the Song Dynasty. Especially in the Song Dynasty, Jiangxi Poetry School was regarded as the ancestor by Du Fu. His influence is enormous.
