First of all, Han Fu regards "nature" as an independent aesthetic object, which opens up the subject area of literary creation.
In pre-Qin literature, nature is not an independent object that can be photographed aesthetically, while in Han dynasty, a large number of works are based on nature, with no other theoretical and ideological conditions attached. Since Han Fu, the narrative of scenery itself has a complete aesthetic significance. Although from the general theoretical discussion, natural hunting is only one of the objects of literature and art exhibition, it is an extremely important and dominant display object for China literature. Describing the nature of mountains and rivers with collective and large-scale behavior, Han Fu pioneered the trend. Since then, whenever there is such group behavior, it will form a peak of China's lyric literature.
Secondly, Han Fu consciously emphasized the inner feelings of people caused by natural objects, which laid the conceptual foundation of the relationship between things and feelings in literary description.
However, in the description of scenery after the Eastern Han Dynasty, individual concrete objects often reflect feelings with a certain tendency, and this relatively solidified material-emotion relationship system has continued to develop to this day. It can be considered that Han Fu is the founder of this idea. In Han Fu, natural scenery is not only the object of people's feelings, but also the object of allegorical comparison, showing full emotional attachment characteristics. Natural changes can cause emotional changes, and some natural landscapes are endowed with certain emotional characteristics and gradually conceptualized and stylized. In this sense, Han Fu laid the conceptual foundation of the relationship between matter and emotion in literary description.
Thirdly, as an important display object in literary creation, "things" have been highly valued in Han Fu.
This can be seen from the "Rites and Music" in the Western Han Dynasty. Although Sima Qian was dissatisfied with the exaggerated style of describing scenery in Han Fu and called it "empty rhetoric", he also emphasized the connection between "ambition" and "things" when evaluating Li Sao. By the end of the Western Han Dynasty, Liu Xin directly pointed out that Chen's "summit can be endowed" was due to "feeling things and making ends meet". It is Ban Gu who positively evaluates the description of "things" in Han Fu. In Hanshu, Sima Xiangru's fu is "knowledgeable and colorful". As far as the actual expression effect is concerned, Han Fu may seem to pay too much attention to the description of things and not enough attention to "ambition" and "Tao". However, from the standpoint of the development and evolution of literature, we appreciate it because of its meticulous description of scenery, which effectively stimulates people's feelings and interests in "things", thus stimulating literature describing scenery.
Fourthly, Han Fu attaches great importance to literary expression.
Starting from Han Fu, this discussion really focused on literature itself. Of course, in the discussion before and after the Han Dynasty, Han Fu often appeared as the object of attack. On the one hand, it has been criticized by writers, which is also what Yang Xiong mentioned many times in "Fa Yan", "Beauty has no words" and "elegance has little words". On the other hand, in the era of Wang Chong and Ban Gu in the Eastern Han Dynasty, the crusade became more intense. The characteristics of the main prose of Han Fu have brought the following important consequences: First, people are aware of the existence of another special article type besides academic, political and historical articles. Secondly, because Emperor Wu of the Han Dynasty and Emperor Cheng liked parallel prose, the Fu family sprang up suddenly, forming a prosperous era of parallel prose, which was spectacular for nearly 800 years. It has effectively promoted the development of literary prose, from "Mo Shan Pan Shui" to the Eastern Han, Wei and Jin Dynasties, showing personal feelings and the interests of ordinary people.
