Du Fu is an emotional person. He did not have a long relationship with Li Bai, but when Li Bai was in danger, he was haunted by his dreams and repeatedly wrote touching poems such as "Dream of Li Bai" and "Embrace Li Bai at the End of the World". When he left a house where he had lived in Kuizhou, he could not forget the old woman next door who used to come to his yard to beat dates for food. He wrote a poem "Wu Lang Again" and asked the new owner to treat her accordingly. Be considerate. Of course, more poems express his strong concern for the war-torn country and the poor people. However, Du Fu's emotions did not flow out like Li Bai's, but were controlled by reason. This character trait directly affects Du Fu's poetry creation: Du Fu prefers and is better at expressing emotions in strict forms and with carefully selected and repeatedly tempered language.
