In the history of China literature, Wei, Jin, Southern and Northern Dynasties are a period of brewing new changes, and many new literary phenomena are gestating, budding and growing, showing new vitality. A vivid, pioneering and creative literary impulse made the literary world appear scene after scene, which is the charm of literature in Wei, Jin, Southern and Northern Dynasties. Generally speaking, this new change can be summarized as the following three points: literature enters the stage of consciousness, and literary creation tends to be personalized; The rise of metaphysics and the introduction of Buddhism have brought new factors to literary creation; The discovery of formal beauty of language and its application in literature. As far as the development of style is concerned, five-character poems have inherited the tradition of Han Yuefu, enhanced the poet's personality, and achieved considerable development and reached its peak; The prosperity of a poetic prose, namely parallel prose, became an important literary phenomenon in this period. China literature has added a new lyric style, which can give full play to the formal beauty of China language; In the Han dynasty, the great fu which was in its heyday evolved into a lyrical small fu, and the prosperity of parallel prose added the elements of parallel prose. Parallel Prose and Parallel Prose reached their peak in Liang and Chen Dynasties. Seven-character ancient poems were established at this time and made gratifying achievements; The fresh breath of folk songs in the Southern and Northern Dynasties stimulated poets to try new things. Coupled with other factors, quatrains prevailed in the Tang Dynasty. At this time, novels have begun to take shape, which laid the foundation for China's novels, and a number of famous novels about strange stories and characters appeared. It took 393 years to brew these new changes. Although it seems a little long, compared with the literary achievements of the Han Dynasty of about 400 years, we can't help but say that the literary achievements of the Wei, Jin, Southern and Northern Dynasties are considerable. Without this period of brewing, there would be no climax of Tang poetry, and there would be no overall prosperity of Tang literature.
