First, thought: many of Li Bai's poems show the idea of pursuing immortality and eating, drinking and enjoying in time; Many of Du Fu's poems show the thoughts of worrying about the world and caring for others. So Li Bai is called "Poet Fairy" and Du Fu is called "Poet Saint".
Second, style: Li Bai often uses exaggerated techniques and vivid metaphors to express his warm feelings; Du Fu often shows his deep sympathy for social reality with vigorous skills and profound thoughts. Li Bai tends to be romantic, while Du Fu tends to be realistic.
Experience: When Li Bai was young, he read a lot of books. "At the age of five, I recite the six armor, and at the age of ten, I read a hundred books", "At the age of fifteen, I read strange books and made Lingxiangru". He also praised Ren Xia, saying that "the fifteen unique swordsmanship was spread all over the governors". (History of China Literature) When he was young, he traveled widely. All these have a great influence on the formation of Li Bai's bold and unconstrained character, and also directly lead to the formation of his romantic poetry style. Li Bai values martial arts and despises Confucianism. He is generous with money and likes drinking. His ideal in life is to be detached from things and actively join the WTO. His personality charm is beyond the reach of others.
Du Fu was born in an official family, and his grandfather Du Shenyan was an important poet in the early Tang Dynasty. Therefore, for Du Fu, career and poetry are both family businesses. He once said to his son, "Poetry is my family". Du Fu was deeply influenced by Confucian culture, and he had a desire to help the monarch all his life. In addition, he was poor all his life, which formed his character of caring for the country and the people and caring for the people. Therefore, his poems emphasize realism.
Li Bai has been wandering between being an official and dancing all his life. In Shu Dao Nan, he described the wonderful and breathtaking mountains and rivers on Shu Dao in Qin Dynasty, from which he revealed some worries about society. He said that "it's too high for a yellow crane to cross" and "the sword pagoda is indestructible" may be a metaphor for his depression at that time. In his "It's Hard to Walk", he used "I threw the food bar and cup aside, I couldn't eat or drink, I pulled out my dagger, and I peeped in four directions in vain. I will cross the Yellow River, but ice blocks the ferry until Taihang Mountain is covered with snow "to describe his difficult situation. Because of Gao Lishi Yang's love at that time, these wise men were kept out of the court, so he issued "It's hard to go, it's hard to go. All roads lead to the same goal, but his optimistic nature makes him persistent in his pursuit of ideals. Full of confidence and longing, he sang the strong voice of "I will ride the wind and waves one day, and set my cloudy sail straight and bridge the deep, deep sea". He wrote in "Nostalgia at Night in Niuzhu": "I looked at the autumn moon on the deck and missed the old general Xie in vain. I have poems; I can read. He hears others, but it's not mine. "Thank you for the story you met, to show that you didn't meet, and you want a bosom friend. All of the above shows that Li Bai is positive about his career. On the other hand, influenced by Taoism, Li Bai had the idea of escaping from the world from time to time and once lived in seclusion in the mountains. In Lushan, he said, "I am a madman of the Chu people and sang a crazy song arguing with Confucius." Holding a green jade stick in his hand, he bid farewell to the famous Yellow Crane Tower early in the morning. It is a habit of my life that the Five Mountains travel far away to find mountains. "It shows his devotion to Taoism, his mockery of Confucianism, and his feelings of getting rid of the secular and pursuing immortal life. In "Dream on Mount Tianmu", he described absurd dreams and expressed his yearning for the fairy world. Finally, he said that "security can make people rich and make me unhappy", which showed his ambition to lead an honest and clean life. It can be said that Li Bai's life is full of sadness in the contradiction between being born and joining the WTO.
Du Fu is much simpler. He has been seeking an official position all his life. "Obey Confucianism and guard the official, but don't fall into the vegetarian business" ("Carving and Fu Biao"). Throughout his life, he believed that one day he could "make the monarch Yao Shun ascend, and then make the folk customs simple". This spirit has been permeated between the lines of Du Fu's poems, as well as his seven laws "Climbing the Building", "Flowers, as high as my window, hurt the wandering heart, because I see, from this height, everywhere sad. The spring scenery of Jinjiang flooded in, and the clouds on the mountain, ancient, varied and changeable. The imperial court, like the North Star, will not change in the end, and the Western Hills of Kohl will not invade Tibet. However, I feel sorry for the sorrow of a long-lost emperor at dusk and talk to Fu Liang at sunset. " This poem can fully reflect the characteristics of Du Fu's poems, and the scenery at the beginning of the poem leads to the author's mood, which is as touching as "where the petals have fallen like tears and where the lonely bird has sang grief". Later, I wrote about how difficult it is for ten thousand people, and finally I wrote a personal report. He wants to make contributions like Zhuge Liang. The whole poem expresses the connection between mountains and rivers and the changes of society through the ages, and it talks about the infiltration and tolerance of personnel with the help of natural scenery. The combination of natural scenery, national tragedy and personal feelings embodies the poet's depressed and frustrated style. His banks of the Yellow River were recovered by the imperial army, and the news is in this distant west station! The north has been recovered! At first, I couldn't stop crying on my coat. Where are my wife and son? There is not a trace of sadness on their faces. However, I packed my books and poems crazily. On a green spring day, I began to go home, singing my songs loudly and drinking my wine. Come back from this mountain, pass another mountain, go up from the south and then go north-to my own town! . "It is about the joy of the poet after hearing the news after Tang Jun conquered Anshi's lair. The whole poem has left a deep impression on people with its smooth rhyme, sincere emotion and fast rhythm. His poem "Up the Mountain" is neat and neat, and the scenery is lyrical. The first two couplets describe the scenery, and the latter two couplets combine their own aging and come down to the root of being down and out. "Leaves fall like the spray of a waterfall, and I watch the long river roll forward. "This is a famous sentence through the ages.
