The Book of Songs is the earliest collection of poems in ancient China, which is divided into three parts: style, elegance and ode. Among them, "the voice of local customs is called wind", "the voice of the imperial court is called elegance" and "the voice of the ancestral temple is called praise", which respectively reflect different musical harmony and uses. Specifically, "wind" is the music tune of various vassal States, reflecting the characteristics and folk customs of various places; "Elegance" is the real music in Beijing, which embodies the sound of court rites and music. "Ode" is the joy of ancestral temple sacrifice, which is used for sacrificial ceremonies. In addition, Elegance and Xiaoya are different in musical style and content. Among them, "broad and quiet, sparse and trustworthy, should sing" Daya "; Those who are diligent and polite should sing "Xiaoya". In addition, the artistic techniques of The Book of Songs are summarized as "Fu, Bi and Xing", which are called "Six Meanings" together with "Ode to Elegant Style". Specifically, Zhu explained in Shi Hua that "Fu refers to the skill of stating facts and directly expressing facts (narrative)" Bi "is the metaphor of one thing to another, which is equivalent to the metaphor of modern rhetoric", that is, to say something else first to arouse the content to be recited, so as to achieve the purpose of touching the scene. These artistic techniques provided rich expressive techniques and skills for the creation of The Book of Songs, and became the precious heritage of China ancient literature.
