What do resentment poems and Yan Yan's poems refer to respectively?

The satirical poems in "Elegant Poems" came into being after the middle of the Western Zhou Dynasty, especially from the end of the Western Zhou Dynasty to Pingdong. Like political poems praising beauty, satirical and resentful poems belong to the "public servant martyrs" in the aristocratic class. As "thinkers" and "spokesmen" of this class ideology, they unfortunately lived in the last days. They must fight against all decadent phenomena in society and face their own setbacks and misfortunes at the same time. Therefore, the purpose of their poetry has to shift from praising beauty to satire and criticism. From the content, these poems can be divided into two aspects: one is satire and exhortation to the rulers, and the other is criticism and criticism to the dark reality of society. These poems are mainly found in Erya and The Scholars. "Celebrating Nanshan" and "The First Month of Xiaoya" belong to this kind of works, and these two kinds of poems are identical in content, which shows the sense and feelings of anxiety of the literati in the Qing Dynasty at that time.

Yan Yan's poems are the only poems that simply reflect the activities of ancient Yan Yan in the history of world literature, and have unique aesthetic value. First of all, they truly show the scene of strict activities, show the harmonious, cheerful and warm atmosphere in strict activities, and form a unique style. For example, Luming Literature reflects the harmony between the subject and the object, while Flute describes the joy and harmony of many brothers getting together. Secondly, Yan Yan's poems also shaped many vivid aristocratic images at banquets. For example, the banquet at the beginning of Guests vividly depicts a group of decadent, hypocritical and ugly aristocratic drunkards.
