What is Bai Juyi's poetic proposition and how is it expressed in his poetry creation?

Bai Juyi's poems advocate creative style. He pays attention to realism, popularity and fable. Pay attention to "writing articles for the time, writing songs and poems for things." The formation of this kind of poetry writing style and proposition is obviously related to Bai's life experience. Bai Juyi and Li Bai Du Fu grew up in a stable and wealthy family when they were young. When he was young, he lived a vagrant life because he avoided the war. With the growth of his age, he, like other literati in this period, has a high enthusiasm for participating in politics. He wrote to Chen many times, and he was keen on it, which made the dignitaries pale and powerless. In the sixth year of Yuanhe, due to his mother's funeral, he returned to his hometown for restructuring. The change of living environment made him think about the whole life, Buddhism and Taoism began to prevail, and his enthusiasm for politics began to decline. Then, Bai Juyi was demoted, which made him more determined on the road of "independence". After returning to Korea, I lost my original enthusiasm. He lives in Luoyang and calls himself "Mr. Zuiyin" and "Xiangshan Jushi". Huichang died in six years.
