What does Yanhuang mean and what does it have to do with history?

Yanhuang was the legendary leader of two ancient tribes in China. Yandi is Yandi and Huang is Huangdi.

Yanhuang is regarded as the ancestor of Chinese civilization, while the Han nationality (the Chinese nation before the Han Dynasty) is called the descendants of Yanhuang. Yan Di, surnamed Jiang, is the leader of the clan. They lived in the Central Plains, and had a long-term inter-tribal conflict with the Jiuli nationality headed by Chiyou, and were finally forced to flee to Zhuolu. With the help of Huangdi clan, Chiyou was attacked and killed. The surname of Huangdi is Gongsun and Xuanyuan. Later, there were three major conflicts between Yan and Huang in Hanquan. Huangdi defeated Chiyou and officially settled in the Central Plains. Now Han people call themselves descendants of the Yellow Emperor.
