Han Fu was an important literary style in ancient Chinese literature and an important part of Han Dynasty literature. The history of the development of Han Fu can be divided into four stages, each stage has its own unique characteristics and representative works. 1 First stage (200 to 180 years before): The first stage of Han Fu was from 200 to 180 years ago. The representative works of this period included Zhang Heng's "Ode to Tokyo" and Cao Zhi's "Ode to the Luo God". These works displayed the fresh and natural, lyrical and freehand style of the early Han Fu, which also marked the beginning of the Han Fu's development towards formalization and specialization. 2nd Stage (180 - 220 AD): The second stage of Han Fu was from 180 to 220 A.D. The representative works of this period were Sima Qian's Records of the Historian and Ban Gu's Han Shu. These works used history as the theme to express the objective description of historical facts and profound thoughts, which marked the beginning of the development of Han Fu in the direction of history and objectification. 3rd Stage (220 - 280 AD): The third stage of Han Fu was from 220 AD to 280 AD. The representative works of this period included Du Mu's "Ode to the Red Cliff" and Su Shi's "Water Melody". These works showed the bold and unconstrained style of the late Han Fu, which marked the beginning of the development of Han Fu in the direction of specialization and formalization. 4th Stage (280 - 360 AD): The fourth stage of Han Fu was from 280 AD to 360 AD. The representative works of this period included Liu Yuxi's "Humble Room Inscription" and Wang Bo's "Preface to Tengwang Pavilion". These works showed the abstruse style of the late Han Fu, which marked the beginning of the development of Han Fu in the direction of abstract and symbolic.
