The "order" mentioned by the landlord is a kind of song.
Say the poem first:
China's ancient poems can be roughly divided into two categories.
One is called ancient poetry (or "ancient style"). The name originated in the Tang Dynasty. In the Tang Dynasty, the new metrical poems that appeared at that time were called modern poems, while those that originated from less metrical restrictions before the Tang Dynasty were called ancient poems. According to the Tang Dynasty, later generations called Yuefu folk songs, poems written by scholars before the Tang Dynasty and poems written by scholars after the Tang Dynasty "archaic poems". According to the number of words in poems, there are four words (such as The Book of Songs), five words (such as Han Yuefu's poems), seven words (such as Ge Yanxing by Cao Pi) and miscellaneous words (such as Li Bai's Difficult Road to Shu). Classical poetry rhymes freely. The other is called modern poetry (or "modern poetry"), which is a new style of poetry that appeared in the Tang Dynasty.
The other is called modern poetry, which is divided into two types. One is called "quatrains", each sentence has four sentences, five short words and seven short words. One kind is called "metrical poem", each poem has eight sentences, five characters are abbreviated as five laws, seven characters are abbreviated as seven laws, and more than eight sentences are called excluded laws (or "long laws"). The rhythm is very strict. There are definite sentences (except arrangement), definite characters in sentences, definite rhymes (definite rhymes), definite tones (definite tones of each word in the poem) and definite couplets (the two rhymes in the middle must be aligned).
Say one more thing:
Ci is a genre evolved from poetry. Ci is a poetic style that rose in Sui and Tang Dynasties. The formal characteristics of words are "fixed tone, fixed sentence and fixed words". Every word has a title called "epigraph".
The number of words is relatively short, and the shortest is only a dozen words. For example, the 16-character order, the longest is only 240 words, such as the preface to Yingying. Generally speaking, less than 58 words are considered as "minor melody", 59 to 90 words are considered as "alto", and more than 9/kloc-0 words are considered as "long tune". Most words are segmented in structure, and a paragraph is called "a paragraph" (or "a piece") in music.
The last song:
Qu is a genre of classical poetry that rose after poetry and prevailed after Yuan Dynasty.
Qu can be divided into Sanqu and Drama. Sanqu is only used in oratorios,
Drama enters drama and becomes lyrics. There are Qupai and Gongdiao. Qupai is the musical form of a tune, which stipulates the number of sentences, words, levels and rhymes of the tune. Each tune belongs to a palace tune, and each palace tune has several tunes.
The system of Sanqu is divided into two types: the first poem and the number of sets. The basic form of poetry is a single song, and each poem has only one tone, which rhymes to the end; The number of songs (also known as "songs") is to connect many songs into a group in the same palace tune to sing a content, which can be used not only to write scenery and express feelings, but also to describe a story fragment.
