"Poetry has four sections and one line" means that a poem is divided into four sections, and each section is a line. For example, Wang Zhihuan, a poet in the Tang Dynasty, wrote a poem with four sentences and one line, with five words in each sentence, four sentences in each section and four lines in each section. This poem describes the scene of climbing high and looking far, and expresses the author's love for the great rivers and mountains of the motherland and his feelings about the passage of time. Therefore, "four verses and one line poem" is a form of poetry, which means that each verse is a line, and there are four verses in * * *.
