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.
2. The most fundamental difference in Du Li's creation lies in his different attitudes towards subjectivity and objectivity. In Wang Guowei's words, Li Bai is a' subjective poet' and Du Fu is an' objective poet'. Du Fu is good at objective description, his representative works are narrative poems, and lyric poems are also objective.
Li Bai is good at self-expression, most of which are lyric poems, and narrative poems are also lyrical. His poems always focus on "self", emphasizing and promoting the role of the subject, and even reaching the level of controlling and conquering the object (describing the object). For example, "Shu Dao Nan". The poet has repeatedly lamented that "it is difficult to learn Shu Dao and go to heaven", which was originally intended to imply that the poet's image is everywhere.
The social content of Du Fu's poems is directly presented through real and vivid pictures of social life. So it's easy to recognize. The image of Li Bai's poems is mainly the poet himself, not the objective social life, so his social content is not easy to be understood.
