According to historical documents and oral materials of Miao people, Miao ancestors first lived in the middle and lower reaches of the Yellow River, and their ancestors were Chiyou. They moved to Jianghan Plain in the "Three Miao" era, and then gradually moved south and west to the southwest mountainous area and Yunnan-Guizhou Plateau due to war and other reasons.
After the Ming and Qing Dynasties, some Miao people migrated to Southeast Asian countries, and in modern times they migrated from these places to Europe and America.

The origin of Miao nationality
In ancient times, Miao people were called "Jingchu", "Man Jing" and "Na Man", and that's it. After Yu brutally cut down three seedlings, there were no records of three seedlings in the Central Plains literature.
Different appellations of Jingchu,, and Na Man all refer to the * * * status of Miao people. His predecessor was Sanmiao, and the descendants of Sanmiao reappeared in history under the abstract guise of "scenery", "Chu" and "Man". These appellations confuse the appellations of Miao and other nationalities.
After the Song Dynasty, Miao was separated from some mixed names of "Man" and became a single national name.
