If ancient Chinese literature is studied in different dynasties, it will be difficult to grasp the connection between the mainstream literary forms of each dynasty - this is the educational characteristic of literary history in Chinese middle schools. One of the requirements for the Chinese major is that students must grasp the connections and differences between mainstream literature in various periods. For many people who have not systematically studied ancient Chinese literature, "landscape poetry" and "idyllic poetry" are just labels. With the amount of ancient literature reading in middle school, it is normal for these labels to be put down as soon as they are picked up. But in fact, the cultures represented behind these labels are not isolated, but influence each other and support each other to be born, evolve and then become their own school. Moreover, the poetry of each style does not simply express the literal meaning of the name of that style, but also contains its origin, process and results. For example, the "Poems about Immortals" that emerged in the Wei, Jin, Southern and Northern Dynasties were already mature in this period. It includes the author's failure to obtain an official position, lamenting the political darkness, despairing of reality, and turning to seek a beautiful world, yearning for a perfect fairyland, and using his imagination to wash away his sorrow. There are thoughts on reality, the relationship between man and nature, and occasionally the ultimate issues of philosophy are mentioned. It is not inferior to the questioning of human nature in the outstanding Western literary masterpieces of the same period - this is a refutation of the fact that ancient Chinese literature is inferior to Western literature in depth.
