Because Li Shangyin is the head of a county, he has to sacrifice great events, so he wrote this poem with the title. Another view was put forward by Liu Yang, who believed that this poem was written in March and April of the second year of Dazhong, when Li Shangyin left Guilin and stayed in Beijing. (See Biography of Li Shangyin)
Li Shangyin, the author of this poem, lived in the late Tang Dynasty, which was in decline. He was deeply dissatisfied with the fatuity of the emperor, the eunuch's power and the domineering of the buffer region. Moreover, Li Shangyin was involved in the party struggle between Niu and Li, and was repeatedly excluded.
Therefore, he expressed his feelings by hanging Jia Yi, and satirized the behavior of Emperor Wen of the Han Dynasty. Although he could seek the virtuous, he did not know the virtuous, which reflected the social reality of the late Tang Dynasty-that is, the emperors of the late Tang Dynasty, like Emperor Wen, seemed to be enlightened, but in fact they were groggy and incompetent.
Extended data:
Jia Sheng is a poem with sharp words, profound satire and deep feelings, but extremely restrained and wonderful. Because the first few sentences are gradually upgraded around "attaching importance to morality", the third sentence is quoted but not sent, and the derogatory effect of the last sentence formed by strong contrast is particularly powerful, which is the clever use of anti-falling techniques.
Thus, it is revealed that the feudal rulers are seemingly seeking and respecting the virtuous, but in fact they can't know the virtuous and benevolence, and that the essence of misfortune is hidden under the appearance of winning favor. The whole poem expresses a thorough discussion of police strategy in the style of singing and sighing.
There are artistic dialectics in the artistic treatment of right and wrong, right and wrong, light and heavy, hidden and obvious, and inheritance, and the artistic style implied by its new police is gradually revealed through this series of successful artistic treatment.
