One represents realism and the other represents romanticism, which has a great and far-reaching influence on later China's poems and even the whole ancient China literature.
The Book of Songs
China's earliest poems. It collected 305 poems in about 500 years from the early Western Zhou Dynasty to the mid-Spring and Autumn Period. The pre-Qin dynasty was called "Poetry", or the integer was called "Poetry 300". In the Western Han Dynasty, it was honored as a Confucian classic, formerly known as The Book of Songs, which has been in use ever since.
The Book of Songs is mainly composed of four words and miscellaneous words. Structurally, the form of repeated chapters and sentences is often adopted to enhance the lyrical effect. Only a few words are changed in each chapter, but it can receive tortuous and changeable artistic effects. In language, we often use disyllabic rhymes, reduplications and conjunctions to describe things and imitate sounds, which is poor. "Less is always more, and the situation is very clear." In addition, some rhymes in The Book of Songs, some rhymes every other sentence, some rhymes to the end, and some rhymes in the middle. The rhyming rules of modern poetry are almost all in the Book of Songs.
Chu Ci is a form of poetry created by Chu people represented by Qu Yuan in China during the Warring States Period. The name of Chu Ci was first seen in Sima Qian's Historical Records and Biographies of Cool Officials in the early years of the Western Han Dynasty. In the Han Dynasty, Chu Ci was also called Ci or Ci Fu. At the end of the Western Han Dynasty, Liu Xiang collected 16 works by Qu Yuan, Song Yu and Huainan Xiaoshan, Dong Fangshuo, Wang Bo and Liu Xiang in the Han Dynasty, and named them "Songs of the South". Chuci became the name of poetry collection again. Qu Yuan's Li Sao is a masterpiece of Chu Ci, so Chu Ci is also called Sao Style or Sao Style.
