What kind of ancient poems do quatrains belong to?

quatrains, also known as truncated sentences, quatrains and quatrains, are short and pithy. It is a popular genre of Han poetry in the Tang Dynasty, and it belongs to a form of modern poetry. The word quatrains first appeared in the Qi and Liang Dynasties in the Southern Dynasties. Xu Ling's "Ode to the Jade Platform" in the Chen Dynasty contains four poems with five words and four sentences. I don't know the author's name, and it is entitled "Ancient quatrains". At this time, the quatrains refer to a small poem with five words, four sentences and two rhymes, and do not require balance and harmony. Jue means "cut off", and the ancients used four poems with four unique sentences to complete an ideological concept. The quatrains are divided into two categories: the absolute and the ancient. Rhythm is only after the rise of rhythmic poetry, which requires leveling. Ancient times existed long before the appearance of regular poems.

The ancient wood was covered with a short canopy in the shade, and a cane helped me cross the east of the bridge.

I want to get wet with clothes, and my face is cold with willows.
