Both of them are unsuccessful in their careers. But their basic differences in personality lead to completely different attitudes towards unsuccessful careers! In Li Bai's character, on the one hand, he hopes that he can [help the poor and secure the country] and gain his own survival value from his political achievements; On the other hand, after being disappointed with the reality, he expected himself to climb Yushu for a long time. You can really transcend the secular and avoid the right and wrong in the world! However, detachment from the world is beyond the reach of Li Bai, who loves the world. Therefore, he struggled between two desires to gain his sense of life value, which resulted in a helpless and powerless mental journey; Du Fu, however, was in an Anshi Rebellion, and he had profound thoughts on people's sufferings. Although his official career was bumpy, due to the hardships of the people in the war (or maybe he never really had a chance to realize his ideals), he was more persistent in helping the people tide over the difficulties, so he could concentrate on his pursuit, and his feelings of worrying about the country and the people could be seen everywhere in his poems.
2. Li Bai's poems are inspired by the current thoughts and constructed by intuitive impressions, looking for words that suddenly meet in his mind to express. Therefore, in the presentation of poetic style, it is not only magnificent, but also unrestrained and natural; When Du Fu wrote poems, he thought carefully about every word. He must rack his brains and make sure that there is no word in his stomach that can be used better. Du Fu may not be unable to write poems based on the inspiration of current thoughts, but he must feel that the creation based on inspiration is too rough, and even as far as his creative experience and ideas are concerned, only constant refining can have the best performance; Li Bai may not be inspired by intuition, but more often, Li Bai finds that the words he flashed at the beginning are the best display of his feelings and thoughts. Even if there are some flaws, in order to show the best situation in his mind, he is bound to be unwilling to tinker with the trivial details of the text.
