In the history of literature, when it comes to old poetry, it is generally divided into two genres, namely "ancient poetry" and "modern poetry". The so-called ancient poetry and modern poetry are not completely divided by the times, but only a genre. Let's not misunderstand the meaning of words. As for new poems, that is, free poems in vernacular Chinese, they are not among the old poems. Don't misunderstand that they are modern poems.
The so-called modern poetry (also known as modern poetry, as the ancients called it) is relative to ancient poetry. They developed from "New Style Poetry" in the Qi and Liang Dynasties into distinctive poems. In this respect, Shen Yue, a poet, established a set of phonological theories, which first laid the foundation for metrical poetry. At first, it was limited to five words, and seven words were created by people in the Tang Dynasty.
Rhyme and quatrains are two major parts of modern poetry. If you understand the metrical poem, you can also understand the quatrains. Because quatrains come with metrical poems.
Metric poetry is also divided into five words and seven words, which is a poem with eight sentences each. They are composed of certain parallelism and duality, harmonious syllables, neat chapters and sentences. The author can't go beyond its scope and limitations at will.
Ping means that every word has four tones: Ping, Qu, Qu and Jin. What doesn't belong to the flat sound is the snoring. On this point, we will discuss it in detail below. Every sentence of a metrical poem or quatrain is restricted by a fixed level tone.
The so-called duality is the four sentences in the middle of the rhyme, which literally must be a pair, and the opposite is a pair. The first four sentences and the last four sentences are not arranged. Three or four sentences are called "front connection" or "parallel connection"; Five or six sentences are called "back couplet" or "neck couplet". These opposites, like the Shuang Ye of a door and the two wheels of a car, all function words and real words must be measured by Thai baht. Intentionally right, right thing, right thing? There are many objections and methods. Here, let's take a look at Bai Juyi's five-character poem "Grass":
The long grass is so lush that the withered grass will thicken the color of the grass every autumn and winter. Wildfire can't burn it out, but the spring breeze can revive it.
Sweet they pressed on the ancient highway and reached the crumbling gate. Oh, my friend's prince, you left again, and I heard them sigh behind you.
