What is Bai Juyi's poetic achievement?

Bai Juyi was enthusiastic about helping the world in his early years, emphasizing the political function of poetry and striving for popularity. He wrote 60 poems, New Yuefu, Qin Zhongyin, which truly made people sick by singing only, and every sentence must be tuned, just like Du Fu's "Three Officials" and "Three Farewells". The long narrative poems "Song of Eternal Sorrow" and "Pipa Journey" represent his highest artistic achievements. Middle-aged people encounter setbacks in officialdom. "Since then, the career has been long-term, and the world has never been opened." But he still wrote many good poems and did many good things for the people. Hangzhou West Lake and Bai Causeway commemorate him. In his later years, he sent his feelings to the mountains and rivers, and also wrote some small characters. There is a poem for Liu Yuxi: "Don't listen to the old songs, but listen to the new word Yang Liuzhi. It can be seen that he has read some new words. Among them, Flowers Are Not Flowers is quite good.
