About many years ago, it was in China's first collection of poems, The Book of Songs.

The Book of Songs is the first collection of poems in the history of Han literature in China. It collects the history from the early Western Zhou Dynasty to the middle of the Spring and Autumn Period, that is, from 1 100 to 600 years ago, about 2,500 years ago. There are 305 poems in about 500 years, also known as "300 poems". It was originally just a collection of poems, but since the Han Dynasty, Confucian scholars have put "300 Poems"

The poems in The Book of Songs are originally the lyrics of music. According to the nature of the original song, it can be divided into three categories: wind, elegance and ode, and its expression techniques can be divided into fu, bi and xing. Together with wind, elegance and praise, they are called "six meanings". The Book of Songs, also known as Poems or Poems 300, is the earliest collection of poems in China with a history of 2600 years.
