What is the theme of the poem?

Poetry themes include nostalgia poems, object-chanting poems, pastoral poems, war poems, travel poems, in my heart forever poems, farewell poems and so on.

In the content of object-chanting poems, an object is described and some characteristics are grasped to describe it. Ideologically, people often express their will by supporting things, from things to people, from reality to emptiness, and write spiritual character. Commonly used metaphor, symbol, personification and contrast.

Cao Cao created landscape poetry, and Tao Yuanming created pastoral poetry in the Eastern Jin Dynasty. In the Tang Dynasty, the school of landscape pastoral poetry represented by Wang Wei and Meng Haoran appeared. Landscape pastoral poetry is good at describing natural scenery, pastoral scenery and comfortable seclusion life, with meaningful and beautiful poetic landscape, quiet and elegant style and clear and elegant language.

War Poems: Poems describing frontier fortress and war, which existed in the pre-Qin period and developed into the Tang Dynasty. Because wars are still frequent, and rulers value martial arts over literature, it is easier for scholars to win fame and fortune by participating in the frontier court than by taking the imperial examination. In addition, in the prosperous Tang Dynasty, the active and vigorous atmosphere of the times led to the great development of frontier poems, forming a new school of poetry, with representatives such as Gao Shi, Cen Can and Wang Changling.

Travel poems and in my heart forever's poems: The ancients' long-term absence as officials, long-term wandering, or long-term frontier defense always aroused strong homesickness, so there are many such poems. They either write about the thoughts of staying on the trip, or about missing relatives and friends, or about homesickness, or about being pregnant in the boudoir. In writing, I feel hurt by touching the scene, feeling in time, expressing my feelings with things, expressing my feelings because of dreams, or expressing my feelings with wonderful metaphors.
