The Book of Songs is the earliest poetry collection in my country, covering more than 500 years of poetry from the early Western Zhou Dynasty to the mid-Spring and Autumn Period. In addition, there are 6 poems with titles but no content, that is, with titles but no words, which are called Sheng poems, also known as "Three Hundred Poems". In the pre-Qin Dynasty, it was called "Poetry", or the whole number was called "Poetry Three Hundred". It was revered as a Confucian classic during the Western Han Dynasty and was first called the Book of Songs, which is still in use today.
