Appreciate the people described in the trilogy of nostalgic poems.

The memory of ancient poetry is generally the memory of ancient people and things. Poetry about history often distorts historical facts and reality, or regrets personal experience or criticizes social reality. For example, Su Shi's "Niannujiao Red Cliff Nostalgia" laments personal experience, the contradiction between ideal and reality, and achieves nothing in his career. Xin Qiji's Ode to Yule, Jingkou Gu Beiting and Nostalgia expressed his dissatisfaction with the imperial court's drag out an ignoble existence and attacked the social reality. There are also poems about history, which only reflect and evaluate history calmly and rationally, or just describe it objectively. The poet's own experience is not among them, and the poet's feelings are just the sound outside the painting. For example, Liu Yuxi's Wuyi Lane compares the past and the present, expressing the poet's sense of historical vicissitudes.

Those who admire history and cherish ancient poetry should first understand historical facts and allusions, then understand intentions and feelings, and finally taste techniques.
