Du Fu's poetic style was formed during the Anshi Rebellion, and gradually formed after suffering. Du Fu went deep into the society, cared about the sufferings of politics and people's livelihood, and attached importance to realism. 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. He inherited Du Fu's realistic style from the middle Tang Dynasty to the Song Dynasty, especially the Jiangxi Poetry School in the Song Dynasty, which took Du Fu as its ancestor. His influence is enormous.
In April of the 6th year of Yuanhe (8 1 1), Bai Juyi settled in Wei Village due to his mother's death, and his beloved daughter Jin Luanzi also died in this year. Bai Juyi lived in Weiwei village for more than three years, and was poor and ill. His good friend Yuan Zhen often gave money to help him. In the winter of the ninth year of Yuanhe (8 14), the prince was awarded the honor of being a good doctor, but later, because of his kindness, he asked for the urgent arrest of the person who stabbed Wu. As a result, he was hated by the prime minister and demoted to the state secretariat, and later demoted to Jiangzhou Sima by the national scholar Wang Ya. This continuous relegation is a great blow and lesson to Bai Juyi, which has greatly changed his thoughts. In order to avoid disaster and suspicion, in Jiangzhou, he "stopped speaking frankly" and "the world stopped speaking". He called himself "a man who has fallen to the ends of the earth", and he traveled and wrote poems as his career, longing for Tao Yuanming, hoping to become a recluse poet, convert to Buddhism and try to get rid of Buddhism. In short, being demoted to Jiangzhou Sima is a major turning point in Bai Juyi's life.
