The ancients said that "poetry expresses ambition, songs always say, voices always follow, and law is harmonious." Poetry is a way and carrier to express one's feelings, a way to express one's thoughts, as simple as that!
"Poetry expresses ambition" means that people should express the author's thoughts or emotional interests, the author's world outlook and aesthetic ideals, and the style of poetry should be elegant. Whether there is true feelings or not is an important symbol to measure a poem.
For example, Du Fu's poem "The Hut Was Blown by Autumn Wind":
"There are tens of millions of luxury houses in Ande, and the poor in the world are happy."
Show the poet's broad mind and lofty ideals incisively and vividly; This feeling of worrying about the country and the people has been stirring the hearts of readers.
Ai Qing, a modern poet, also thinks in his Poetics:
Poetry must be tangible, and poetry is a living sculpture of the soul.
This is the aesthetic pursuit of his poetry.
No matter how gorgeous the soul is, it needs a beautiful coat to package it. This coat is the language art of poetry. Generally speaking, if a poem has good ideological content, it must be expressed by certain artistic forms, and language is the carrier.
As far as ancient poetry is concerned, it can be judged by rhythm, levelness and antithesis. , but also from the rhetoric, rhythm, lyrical way, etc.
For modern poetry, the theme, form and technique are more diversified. Speaking of lyricism alone, there are lyricism by borrowing scenes, blending scenes, lyricism in scenes, lyricism by holding things, and expressing one's mind directly. There are also many ways to express poetry, such as rendering, contrast, setting off, reality, point and face, symbol, etc. Rhetorically, metaphor, personification, exaggeration, parallelism and repetition are often used.
If a poet can master these skills flexibly, whether writing popular poems or pure poems, his poetic language will be beautiful to the bone. Reading such poems leaves enough room for imagination, gives people beautiful enjoyment and makes people want to stop.
