Poetry is mainly about expressions, situations, emotions and moods, which are related to human labor. During the labor process, primitive people naturally made a cry for labor due to the relaxation of their muscles and the use of tools. This naturally produced sound of labor has certain highs and lows and intervals. Within a certain period of time, it either repeats and changes, or changes and has regularity, thus creating a rhythm. This simple rhythm is the origin of the rhythm of music, dance and poetry, as well as the origin of poetry. Mr. Lu Xun made it clear when talking about this origin. He said:
"Before there was literature, human beings had creations. Unfortunately, no one recorded them, and there was no way to record them. We Our ancestors, the primitive people, could not even speak. In order to work together, they had to express their opinions, and then they gradually developed complex sounds. If it was difficult for everyone to lift wood at that time, it would be difficult for everyone. I don't want to publish it. One of them is called "Hang Yu Hang Yu", then this is creation... If the mark is preserved, this is literature; of course he is a writer, that is, a writer, "Hang Yu Hang". "Yu'pai." ("Qiejieting Essays·Menwaiwentan")
During long-term labor, primitive people gradually developed thinking and language due to the development of their brains and vocal organs. Of course, language was just a simple shout at the beginning, and later it gradually developed into distinct syllables that could be used as a tool for human exchange of ideas and social communication. At this time, if you add some language at will during the interval of shouting, even the simplest language, such as "Waiting for people, Xi Yi!" "人" is followed by two words "xi" and "痗". Once this expressive language is combined with rhythmic calls or sighs, it becomes a meaningful poem. Of course, it is the first poem - expression. Poems about emotions and modalities. This situation expressed by rhythmic rhyme is poetry. In the development of thousands of years, starting from the "Book of Songs", this initial poetic sentiment became more and more exquisite and rich, and some famous Chinese and foreign celebrities such as Bai Juyi, Li Bai, Du Fu, Mao Zedong, etc. emerged. great poet.
