There are always different opinions about the origin of Yao characters. Among them, the clues in the History of the Origin of Nan Man written by historian Mr. He Guangyue are more credible: the Yao ancestors were good at making pottery and pots in the Neolithic Age, so the earliest Yao ancestors were called "kiln people"; Later, the production of ceramic pot blanks developed from manual to rotary shaking, and the kiln people changed their names to "shaking people"; Lei, one of the four surnames of Yao ancestors, originated from the wife of Huangdi (Lei Zu), who invented sericulture, so Yao people were good at sericulture and derived the name "Ji Min"; After Chiyou led Sanmiao and failed in the war with the Yellow Emperor, he experienced the conquest of Xia, Shang and Zhou dynasties, and some of them were regarded as slave workers, called corvee or corvee, that is, the people who were killed (Zhou went to the generation outside Feida Ridge, saying: Since then, the people of all previous dynasties have constantly resisted the oppression of feudal rule, gathering mountains without paying taxes, which was also called "Mo Yi" in the Song Dynasty, meaning those who did not pay taxes and did not work; The ruler of the Yuan Dynasty thought that such a man who did not give corvee and slash and burn was a savage, so he changed the word "stubborn" next to the dog to "arrogant" and called it "arrogant people". After the founding of the People's Republic of China, it adopted the suggestions of the democrats and widely obtained the consent of the nation, and took the word "Yao" beside Meiyu as the unified name of the nation: Yao.
