Does Chiyou really exist in history?

Yes, but history and legend are different.

According to legend, Chiyou is a bull's head with wings on his back. He is the leader of the ox totem and bird totem clan, and the double horns of the bull head are the dragon horns in the traditional dragon culture. He has eighty-one brothers, all of whom are bronze heads, eight arms and nine toes, and all of whom have extraordinary skills. About 5,000 years ago, the Yellow Emperor started a war with the Chiyou tribe in Zhuolu County, Hebei Province, and Chiyou died. Dongli Jiuli tribe merged into Yanhuang tribe, forming the earliest subject of the Chinese nation today.

In fact, Chiyou may be a tough and ferocious tribal chief. He led troops to fight Xuanyuan Huangdi and was defeated and killed. As for his strange images, they are all legends. At present, there is no evidence that there were other anthropoid races in ancient times.
