First of all, in the early Tang Dynasty, from the first year of Emperor Gaozu's Wude (6 18) to the early year of Xuanzong's Kaiyuan (7 13), the country was the most powerful for about one hundred years. At that time, there was a strong rule, and many people divided it like this, mainly because the economy in the early Tang Dynasty was really strong, not only the rule was strong, but also the culture was strong. Yang Jiong, Lu and Luo were also four outstanding figures in the early Tang Dynasty.
Followed by the prosperous Tang Dynasty and the middle Tang Dynasty, from the early years of Xuanzong Kaiyuan (7 13) to the early years of Daizong Dali (766), it was also very strong, prosperous and peaceful, about 50 years. The most representative poets at that time were Li Bai and Bai Juyi, both of whom were great poets. At first, the Anshi Rebellion was mentioned because the dividing line of Anshi Rebellion divided the Tang Dynasty into two parts, that is, there was a process of prosperity and decline.
Followed by the Middle Tang Dynasty, from the first year of Daizong Dali (766) to the ninth year of Wenzong Taihe (835) for about 70 years. At this time, the main problem is not that the degree of peasant uprising has not increased enough, but that there is chaos in the DPRK, and many people are fighting with each other, so the economy of the Tang Dynasty is slowly retreating. The representative poet at that time was Yuan Zhen, and we can also learn a lot about the difficulties of being an official in the DPRK from his collection of Yuan Zhen.
The late Tang Dynasty refers to the period of about eighty years (835-907) after the literary genre was summed up. This is also the loneliest time. In fact, the Tang Dynasty was about to be abolished at this time, and the last emperor was useless. The representative poet at this time was Li Shangyin.
In fact, no matter who put it forward, I think this is the history of a dynasty, and we can all discover and study it.
