How to evaluate the value of poetry

The overall style of poetry is devoted to the exquisite carving of artistic forms, replacing utilitarian purposes with gloomy symbols, paying attention to the expression of feelings and emotional psychology, taking sadness as beauty, desolation as beauty, indifference as beauty, elegance as beauty and exquisiteness as rhyme. The reasons for the formation of this poetic style. First of all, due to social chaos, the political situation gradually collapsed, eunuchs monopolized power, and the struggle between the two parties was fierce, which seriously weakened the central political power of the Tang Dynasty. In such a regime, the psychological state of the landlord class intellectuals has undergone new changes. Although they still miss the imperial court, care about state affairs and have hope, they have lost confidence. Many of them show a unique sense of melancholy when thinking about the political situation and history.
