Hiking, reading at night and giving Liu Jingwen are all five-character sentences?

What I read in "Mountain Walk" and "Night Book", and what I gave to Liu Jingwen, are not all five-character quatrains. Mountain Walking is a poem written by the poet Du Mu, which describes and praises the mountain scenery in late autumn. What I saw in the night book was a five-character quatrain written by a poet in Qing Dynasty. To Liu Jingwen is a seven-character quatrain written by Su Shi, a writer in the Northern Song Dynasty.

Five-character quatrains, a genre of China's traditional poems, are short poems with five words and four sentences, which conform to the rules of metrical poems and belong to the category of modern poems. This style originated from Yuefu poems in Han Dynasty, was deeply influenced by folk songs in Six Dynasties and matured in Tang Dynasty. There are only twenty crosses in each song, which can show a fresh picture and convey a true artistic conception.

Seven-character quatrains This poem consists of four sentences, each with seven words, which has strict metrical requirements in rhyme and cohesion. The poetic style originated from Yuefu songs in the Southern Dynasties or Yuefu folk songs in the Northern Dynasties or folk songs in the Western Jin Dynasty, and its stereotypes matured in the Tang Dynasty.
