How does pipa express the author's thoughts? Pipa appreciation

1, this poem is a narrative poem, which mainly tells the story that Bai Juyi met a pipa girl on a moonlit night when he was in exile in Jiangzhou and seeing off guests on the river. There are two characters in the poem: the pipa girl and the poet himself. The former is the main and the latter is the object. It not only expresses sympathy for the sinking experience of the pipa girl in her later years, but also expresses the poet's desolate mood.

2. Pipa Xing was written in the 11th year of Yuanhe (AD 8 16), which is a seven-character ancient poem. When Bai Juyi was appointed as an admonition officer, he dared to remonstrate, sympathized with the sufferings of the people, and wrote a lot of satirical poems, which angered Tang Xianzong and offended powerful people. In the tenth year of Yuanhe, Prime Minister Wu was assassinated by Li Shidao, a buffer region. In desperation, Bai Juyi wrote a letter asking for an assassin, which violated the interests of the powerful and was accused of exceeding his authority and demoted to Jiangzhou Secretariat. He was framed for his poems "Appreciating Flowers" and "New Realm" and later demoted to Jiangzhou Sima. Jiangzhou was regarded as a "wild land" at that time. Jiangzhou Sima, though nominally a secretariat assistant, is actually a sinecure, which is a great irony to Bai Juyi. He was demoted, in fact, it was an unjust case, repeatedly hit, feeling sad, full of frustration and anger. The following year (in the 11th year of Yuan Dynasty), I saw Pukou, met a pipa girl, and wrote this famous song handed down from ancient times.
