The realistic spirit of Du Fu's poems comes from his highly mature realistic creation method, which is mainly reflected in the narrative poems with a large number and high quality.
First, Du Fu is good at selecting people and things with typical significance, making artistic generalizations, shaping numerous characters and painting a broad picture of social life. The old man who fled over the wall, the old woman and Yang who served in the emergency river, the man who was recruited in Xin 'an, the bride who got married in the morning, the homeless single man, the old maid who paid money in Kuizhou, Zhuge Liang who tried his best, Tian Fu who advised drinking diligently, and the incompetent minister … formed a portrait gallery. Vivid and vivid images with so many typical meanings are outstanding contributions of Du Fu's poems.
Secondly, Du Fu is good at integrating subjective thoughts and feelings into the description of objective facts, so that the characters can speak with facts themselves, which is naturally touching. The author finds problems from reality.
