The legends of the Tang Dynasty and the supernatural stories of the Wei and Jin Dynasties are both classic works in the history of Chinese literature. There is a certain connection and overlapping relationship between the two. Wei and Jin Zhiguai novels referred to novels with myths and legends, strange phenomena, and strange stories as the main content, such as Strange Tales from a Chinese Studio and Journey to the West. These novels often contained the influence of Buddhist ideas, showing the reflection of life and death, reincarnation, soul and other philosophical issues. Tang Legends referred to the legendary novels passed down from the Tang Dynasty, including many stories such as The Peony Pavilion, Water Margins, Romance of the Three Kingdoms, and so on. Different from the supernatural stories of the Wei and Jin Dynasties, the legends of the Tang Dynasty mainly reflected the social life of the Tang Dynasty, the style of the Tang Dynasty society, and the thoughts and feelings of the people. There are some similarities in the content of the Tang legends and the Wei and Jin supernatural novels. They both contain some myths and legends, strange phenomena, and strange stories. At the same time, they also reflect the people's thinking about life and death, reincarnation, soul and other philosophical issues. However, in terms of form and style, the Legend of Tang was more mature and diverse. It adopted a variety of techniques such as narration, description, and discussion, which had more distinct artistic characteristics. Although the legends of the Tang Dynasty and the supernatural stories of the Wei and Jin Dynasties had different origins and contents, they were closely related and intersected, leaving important cultural heritage in the history of Chinese literature.
