What is the technique of Fu?

The technique of Fu was a literary rhetorical device used to give specific images, emotions, and characteristics to the characters, scenes, and plots in the text, so as to make the text more vivid, profound, and touching. The technique of Fu was often used to express the character's personality, psychology, emotions, and behavior to shape the atmosphere of the scene. The situation and atmosphere strengthened the logic and cohesiveness of the text. For example, in the novel Romance of the Three Kingdoms, Cao Cao's poem "Watching the Sea" could well express his political ambition and greed: East to Jieshi to watch the sea. the water is so clear that the mountains and islands stand tall. The trees grew luxuriantly. The autumn wind blew and waves surged. The movement of the sun and moon seems to come out of it. The stars are bright as if they came out of the village. I'm so lucky to sing songs to express my ambition. In this Fu, Cao Cao expressed his political ambition, greed, and desire for power by giving images, emotions, and characteristics of natural elements such as water, mountains, islands, trees, grass, autumn wind, and great waves. The Fu technique made the text more vivid, profound and touching, and at the same time, it also enhanced the logicality and cohesiveness of the text.
