The literature of an era is bound to be contaminated with the flavor of an era, and the unified atmosphere of the Tang Dynasty is bound to be reflected in the poems of the Tang Dynasty. In the second half of the early Tang Dynasty, the style of poetry changed, which was manifested in the style, theme and genre of poetry. From the perspective of poetic style, poetry gradually got rid of Qi Liang's extravagant habits and showed a fresh and vigorous character; From the content point of view, poetry broke through the narrow theme field of poetry in the Six Dynasties and began to show broad social life and major political issues; In terms of genre, the form of metrical poems is basically established, and the seven-character songs have also developed greatly.
Yang Jiong, Lu and Luo, the four great poets in the early Tang Dynasty, were four poets with small professional positions and high talents from the Tang Dynasty to the marquis of Wu. It should be said that Tang poetry with both temperament and personality started from them. The vigorous atmosphere, outstanding talent and prestige of the Tang Dynasty made the four outstanding men full of the mind and ambition to help the world, but their humble official position and status prevented them from displaying their talents. ? Depressed The four great poets, represented by Shangguanti, developed the theme in their poems, and moved the poems from the palace to the street, from Taige to Jiangshan and Saimo. At the same time, the development of the theme has brought serious thoughts, bold momentum and generous and sad style. Therefore, the poems of Sijie became excellent works with concise poetic style in the early Tang Dynasty. Chen Ziang's creative achievements: Thirty-eight Poems of Meeting is Chen Ziang's masterpiece, while Youzhou Tower and Qiu Ji Guangu and The Second Yan Zhaowang are famous masterpieces. These two poems are also important epic poems in the early Tang Dynasty.
The early Tang Dynasty is also an important period for the development of poetry genre. Yongming style developed into regular poetry, among which Shen Quanqi and Song made the greatest contribution to regular poetry. The so-called "Yongming style" is a new poetic style that began to appear in the first year of Qiyong in the Southern Dynasties. At that time, Shen Yue, a famous poet, studied the harmony of sound, rhyme and tone in poetry according to the four-tone and two-tone overlapping rhyme of Chinese characters, and pointed out eight prosodic defects that should be avoided, which were called "eight diseases". This combination of meter and antithesis forms a new metrical poetic style. Because this new poetic style was created in the following year, it is called Yongming style.
Yongming style laid the foundation for the establishment of regular poetry. On the basis of Yongming style, Shen Quanqi and Song, important court poets in Wuhou period, dualized the four tones, that is, divided them into two flat tones. It also solved the sticky problem of law and completed the transition from legal sentences to legal texts. So as to create a new poetic style with both procedural constraints and broad creative space, that is, metrical poetry. In the process of shaping metrical poems, Song Shen made the greatest contribution, and they finally completed the task of "recalling the sound and getting sick, and the sentences are consistent", so metrical poems were originally called "Shen Songti". The stereotype of metrical poetry is of great significance to the development of poetry and promotes the climax of Tang poetry.
Poets in the early Tang Dynasty also made great contributions to the development of artistic conception. They began to get rid of the flashy atmosphere of the Six Dynasties and devote themselves to poetic artistic conception. Zhang's Moonlit Night on a Spring River is the best one. It wrote the old topic of wandering about thinking about women with the old songs with five tones of Yuefu, but it was praised as "the lonely piece overwhelmed the whole Tang Dynasty" because it opened up a new artistic conception.
