Two: Different family backgrounds. Li Bai has no family background, no one forces him to do whatever he wants, and his personality is unruly. Du Fu's grandfather and father were both officials and were influenced by two people since childhood. Du Fu's thought of benevolence and righteousness is extremely strong, and his poems show individual characteristics.
Three: the background of the times is different. Li Bai, Emperor Xuanzong of the Tang Dynasty, was strong in national strength and broad-minded when he was young, so he formed Li Bai's character. Du Fu, on the other hand, was unfortunate. He became famous when the late Tang Dynasty began to decline. Confucianism made him feel depressed when he wanted to serve his country. Coupled with the thought of worrying about the country and the people, it is even more tragic.
