What is metrical poetry?

The whole poem is as follows

Walking through the flower street and Liuxiang, who knows that my husband is in the bitch's bed. Twenty-eight women dressed very skillfully, and the bridal chamber changed grooms every night.

A pair of jade arm pillows for thousands of people and a little lip for thousands of people to taste. Pretend to be charming, pretend to be false.

Welcome to know how much, I used to cry two lines. I hated it before my death and advised Lang to quit prostitution and go home.

I feel that Yangzhou dream should wake up, and I have infinite affection for my wife.

Metric poetry, also known as modern poetry, is a kind of ancient poetry in China and a poetic style formed after the Tang Dynasty, which is mainly divided into quatrains and metrical poems. According to the number of words in each sentence, it can be divided into five words and seven words. Style and sentence patterns have certain norms, phonology has certain laws, and the changes in use also need to abide by certain laws.

Free verse is a kind of poem with irregular syllables, rhythms and other forms of design. It pursues "organic form" and relies on the natural rhythm of speech. This kind of speech is "natural" to the theme and feelings of the poem. Free verse is not a modern invention, but with the arrival of modernism, it occupies an important position and constitutes a rebellion against the fixed form of19th century poetry. Free verse has no external form to use, and it may be the most difficult to write well compared with previous poems.
