The questions about all kinds of poems are quite complicated. The editor of 300 Tang Poems divides poems into three categories: classical poems, regular poems and quatrains, all of which are equipped with Yuefu. Ancient poems, regular poems and quatrains are divided into five words and seven words respectively. This is a kind of division. The classification of Shen Deqian's Poems on Tang Poetry is slightly different: he did not separate Yuefu, but added the category of five-character poems.
Extended information words are a unique poetic style, which sprouted in the Southern Dynasties and emerged in the Sui and Tang Dynasties. In the Song Dynasty, after a long period of continuous development, Ci entered its heyday. The original name of the word is "Quci" or "Quci", and it is also called: near-style Yuefu, long and short sentences, Quci, music movement, fun, idle poems and so on. It is a song and poem full of feasts, and the epigraph is the name of the tone of the word. Different epigrams have regulations on the total number of words, the number of sentences, the number of words per sentence and the level.
