1. Early Tang Dynasty
If it is divided into major historical events, it is from the establishment of Tang Dynasty by Tang Gaozu Li Yuan to the third Xuanwu Gate Revolution. This is a dynasty full of vigor and vitality. During the Zhenguan period, although the society was not fully prosperous, the politics was clear and the people's lives were flourishing. Relying on the unique system of officers and men at that time, Emperor Taizong used foreign troops many times and achieved the greatest results at the least cost. Although it was early, his martial arts were amazing.
Poetry in the early Tang Dynasty has not got rid of the style of Sui Chen period. The poems of Li Shimin, Emperor Taizong and the literati around him are all gorgeous and beautiful, but the official style is wrong and charming. Only a few people, such as Wei Zhi and Wang Ji, can extricate themselves from vulgarity, but they still have not got rid of the influence of "choosing beauty while contending for differences" in the late Six Dynasties. It was not until the four outstanding poets in the early Tang Dynasty (Wang Bo, Yang Jiong, Lu,) developed the content and form of poetry.
2. Tang Dynasty
Naturally, Li Longji came to power after a congenital coup in 7 13 A.D., which began in Kaiyuan and ended several years after the Anshi Rebellion in 766 A.D.. This period is the most prosperous and successful period of Tang 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 create freely in a romantic atmosphere. Therefore, their works are exquisite and beautiful, vigorous and fresh, with wonderful images and harmonious rhythm, which show the artistic characteristics of the times and create a "prosperous Tang Dynasty" that shocked future generations.
3. Middle Tang Dynasty
That is, from the Anshi Rebellion in 766 AD to the end of the Huang Chao Uprising. In the mid-Tang Dynasty, after the Anshi Rebellion was destroyed, eunuchs were autocratic and princes were separated, one after another. But after all, the Tang Dynasty had its own background and finally became a powerful vassal, welcoming Yuan and Zhongxing. Unexpectedly, an unprecedented phenomenon appeared in the Tang Wenzong period.
After the change of Ganlu, eunuch Chou Shiliang proclaimed himself emperor and even killed him at will. For the first time in 5,000 years, there was such a bold eunuch. The change of manna is the dividing line between the middle Tang Dynasty and the late Tang Dynasty. Although politics was broken in the middle Tang Dynasty, great achievements were made in poetry. Poets headed by Bai Juyi advocated the new Yuefu movement with Yuan Zhen, and Li He, like a meteor, will always be a genius.
4. Late Tang Dynasty
Nature is full of holes and stormy, but "to see the sun, for all his glory was buried in the coming night", and Li Shangyin and Du Mu brought the last glory of Tang poetry. It is natural that Du Li was the most glorious period in the Tang Dynasty and Du Li was the most depressed period.
