What is the format of a short poem?

The format of the short poem is a seven-character quatrain, composed of four sentences.

Each word is a few words or a few quatrains. Five-character ancient poetry is one of the ancient Han poetry genres. It refers to a poem with five words in each sentence, and the whole poem is composed of five words. In terms of syllables, the odd and even matches are more musically beautiful. After the early Tang Dynasty, modern poetry emerged, including five-character rhymed poems and five-character quatrains.
