The first is the early Tang Dynasty (6 18-7 13). In the early Tang Dynasty, Yang Jiong, Lu and Luo, who were known as the "four outstanding poets" in the early Tang Dynasty, gradually completed the process of poetic rhythm, laying the foundation for China's poetic rhythm. Make the Tang poetry present its own face. Through their efforts, the theme of poetry has changed from the extravagance of the palace to the public life of society, and the style has also changed from exquisite and humble to bright and fresh. The most outstanding poet in the early Tang Dynasty was Chen Ziang, who advocated restoring the fine tradition of poetry reflecting real life. Chen Ziang's poetry is vigorous and simple, which opens the way for the development of Tang poetry. The first 50 years are the continuation of formalism literature in the Southern Dynasties. In the last 50 years, four outstanding poets broke through the theme of palace poetry, Shen Song established the form of regular poetry, and Chen Ziang advocated Jian 'an style and denounced Qi Liang's poetic style, which opened up a healthy development path for Tang poetry.
Second, the prosperous Tang Dynasty (7 13-766)
From 7 13 to 766, it was called the prosperous Tang Dynasty, which was the most prosperous and successful period of poetry. Poetry in the prosperous Tang Dynasty has rich themes and different styles. Some praise nature, some yearn for frontier fortress, some praise heroism, and some sigh helplessly. Many poets created freely in a romantic atmosphere, creating a "prosperous Tang Dynasty" that shocked later generations. The most famous poets in the prosperous Tang Dynasty were Li Bai, Du Fu, Wang Wei, Meng Haoran, Gao Shi and Cen Can. Cen Can is good at writing frontier poems, while Gao Shi's poems can better reflect the sufferings of the people. Li Bai, the "Poet Fairy" and Du Fu, the "Poet Sage", are great poets who can truly represent the poetic world in the prosperous Tang Dynasty. Their poems had a far-reaching influence on China's later poetry creation. At the peak of poetry prosperity, great poets with diverse styles and wide subjects appeared. Positive romanticism represented by Li Bai is the mainstream of poetry in the prosperous Tang Dynasty. Political poems and frontier poems embody the style of Tang Dynasty. Du Fu reflected the postwar reality comprehensively and profoundly with the great spirit of poetry in the prosperous Tang Dynasty, paving the way for the development of realistic poetry in the middle Tang Dynasty.
3. Mid-Tang Dynasty (766-836)
Among the outstanding poets in the Middle Tang Dynasty (766-836), Bai Juyi, Yuan Zhen and Li He were among them. Bai Juyi is good at allegorical poems. In his poems, he satirized extortion, opposed the militaristic war and attacked the powerful. In addition, Bai Juyi strives to make his poetic language more popular, fluent, vivid and touching, so he is also loved by readers. Li He is a short-lived poet who only lived for more than 20 years. He was poor all his life, and his official career was not smooth, but his poems were rich in imagination, novel in conception, exquisite in conception, magnificent in words, full of romanticism, strong aesthetic tendency and sad artistic conception. The grim and cold reality with the largest number and widest genre turned the mainstream of poetry into realism, and the new Yuefu movement represented by Bai Juyi ran through the whole middle Tang Dynasty.
4. Late Tang Dynasty (836-907)
The late Tang Dynasty from 836 AD to 907 AD was the active period of poets Li Shangyin and Du Mu. Du Mu's poems are fresh and cold, which is very suitable for him to express his political ambition and passion in his poems. Li Shangyin, with his exquisite structure, magnificent language and gloomy style, reflects the ups and downs he experienced in his official career, and his poems often reveal a sad mood. Whether his famous poem Untitled is a love work or a metaphor of political content is still controversial in China poetry critics. Realistic poetry continued to develop. Pi Rixiu and others inherited the tradition of the New Yuefu Movement, but lacked creativity in art. The poems of Li Shangyin and others were full of dreamy mood in the twilight, and the love theme was very smooth. After Wen Tingyun and Wei Zhuang's founding, Ci developed rapidly in the Five Dynasties.
