The Classic of Poetry, also Shijing or Shih-ching, translated variously as the Book of Songs, Book of Odes, or simply known as the Odes or Poetry (詩; Shī), is the oldest existing collection of Chinese poetry, comprising 305 works dating from the 11th to 7th centuries BCE. It is one of the "Five Classics" traditionally said to have been compiled by Confucius, and has been studied and memorized by scholars in China and neighboring countries over two millennia. It is also a rich source of chengyu (four-character classical idioms) that are still a part of learned discourse and even everyday language in modern Chinese. Since the Qing dynasty, its rhyme patterns have also been analysed in the study of Old Chinese phonology.
Early references refer to the anthology as the 300 Poems (shi). The Odes first became known as a jīng, or a "classic book", in the canonical sense, as part of the Han Dynasty's official adoption of Confucianism as the guiding principle of Chinese society. The same word shi later became a generic term for poetry. In English, lacking an exact equivalent for the Chinese, the translation of the word shi in this regard is generally as "poem", "song", or "ode". Before its elevation as a canonical classic, the Classic of Poetry (Shi jing) was known as the Three Hundred Songs or the Songs.
The Classic of Poetry contains the oldest chronologically authenticated Chinese poems. The majority of the Odes date to the Western Zhou period (1046–771 BCE), and were drawn from around provinces and cities in the Zhongyuan area. A final section of 5 "Eulogies of Shang" purports to be ritual songs of the Shang dynasty as handed down by their descendants in the state of Song, but is generally considered quite late in date. According to the Eastern Han scholar Zheng Xuan, the latest material in the Shijing was the song "Tree-Stump Grove" (株林) in the "Odes of Chen", dated to the middle of the Spring and Autumn period ( 600 BCE).
The content of the Poetry can be divided into two main sections: the "Airs of the States", and the "Eulogies" and "Hymns".
