Most of the literary works in Xia and Shang dynasties existed in the form of poems, which many authors could not prove. The internationally recognized history of China's belief began with the uprising of China people in Zhou Dynasty, or the existence of characters in Shang Dynasty (after Pan Geng moved to Yin), much later than the time when China really entered civilized society. To explore the origin of poetry, we must trace it back to the critical stage when human beings are entering the civilized era, and there may be no words circulating in later generations. Or there are characters that modern people can't decipher (such as the regular symbols on the pottery of Erlitou site in Henan Province), but human civilization has been passed on. Many things are handed down from generation to generation. In the records of later generations, you can always find information from ancient times, such as the following:
"Break bamboo, continue bamboo, fly soil, and exorcise evil spirits." -Wu yue chun Qiu
"Soil, back to their homes! Water belongs to its valley! Insect, don't do it Vegetation, return to its jersey! " -The Book of Rites. Special sacrifice in the suburbs "
"I plow for dinner, dig wells to drink water, work at sunrise and rest at sunset. Dili is nothing to me! " -"Song of Digging the Earth"
From these sentences, we can know that literature existed in Xia and Shang Dynasties.
