Most ancient ballads appeared at the same time as the trinity of ancient music and dance in labor. "Lu Chunqiu Ancient Music" recorded the music and dance of Ge people: "Ge was happy in the past, and three people were happy and full of songs." "Three people" is a collective singing, "oxtail" takes prey as props, "foot wrestling" is a dance with small steps as the beat, and "Eight Ques" is the name of eight original songs. Many people sing with oxtail, which shows that there are many comprehensive art forms in ancient songs. The language of ancient China ballads is extremely simple, mostly two-character, three-character or four-character, with few complicated sentences. First, because the production art was backward and the labor action was simple, the accompanying poems were naturally short, and second, it was related to the low ideological ability and language level of our ancestors. Simple thinking is expressed in simple language, which is naturally short, not carved, not exaggerated and not simple. Ancient ballads originated from life and directly expressed life. Their representation of life is direct, impromptu and frank, which is different from the creative method of expressing reality and expressing emotions by choosing typical life phenomena and characteristic details in The Book of Songs, but it is obviously the source of the realistic spirit in The Book of Songs.
