It is said that poetry is divided into Tang and Song Dynasties. Is there an obvious bipolar classification of poetry in Wei, Jin, Southern and Northern Dynasties?

Wei, Jin, Southern and Northern Dynasties were also divided into two levels. In Wei and Jin Dynasties, Yongming style should be the dividing line. Before Yongming style, it is a poetic form, and after Yongming style, it is another poetic form. The Northern and Southern Dynasties paid attention to the metrical form of poetry, and even exceeded the requirements of the Tang Dynasty, but at this time, poetry did not form a real climate like the Tang Dynasty. Therefore, the poetry of the Southern and Northern Dynasties played a solid role in the development of the poetry of the Tang Dynasty.

The so-called Yongming style is a kind of poetic style in the Yongming era of the Southern Dynasties, and it is a new poetic school that pays attention to the balance and rhyme of poetry. Before the appearance of Yongming style, it was a poetic style before it was preserved. This poetic structure does not need absolute confrontation, which is a bit like the feeling of Song Ci. For example, in The Book of Songs? I'm leaving, Willo Yiyi? ; One more sentence? Today I think, is it raining? . This is a poetic form before the emergence of Yongming style, and the level of the sentences before and after does not require absolute consistency.

During the Yongming period, there was a poet named Shen Yue. He discovered the four-tone change of writing, so he invented the level tone and the level tone antithesis. Moreover, there are few repeated words in the poems of this period, and they are controlled by the tone of the sound, which is more dignified.

The poetic style after the Yongming style in the Southern Dynasties made the four tones of the text more strict, and introduced the tone into the level tone, which also had obvious requirements for the level tone, which also laid the antithesis rules of the poetic style in the Tang Dynasty. For example, the upper part should be collected, and the lower part should be collected evenly to avoid repeating words. At this time, the first four sentence patterns of poetic style are: flat and even, flat and even; Even if it is flat, even if it is flat, even if it is flat, the following poems can be used without confrontation.

By the late Southern and Northern Dynasties, the poetic style was more standardized and standard metrical poems were formed. For example, Xiao in the late Northern and Southern Dynasties attached great importance to metrical poems and wrote many quatrains. Jian Wendi and Xiao Gang, for example, wrote a poem, "HeYin in the Central Banqiaozhou", which was completely done according to the antithesis of peace.
