Background information of Yanhuang comrades.

Chiyou has ethnic relations with Emperor Yan.

Yandi and Chiyou are both developed from Shennong, and belong to the farming tribe alliance. The direct descendant of Shennong is called because of the great achievements of his ancestor Shennong in inventing thunder. The Chiyou tribe is the most powerful of a group of farming tribes developed from Shennong. The reasons for its strength are: first, it is beneficial to its local salt; Second, in the production process of boiling salt, the invention of smelting metal and making weapons.

There are three theories about the battle between Chiyou and Huangdi. One is that after Huangdi defeated Yandi, he defeated Chiyou again to consolidate the throne. The battle between Huangdi and Chiyou seems to be the aftermath of the battle of Huangdi. On the other hand, Chiyou expelled Chi Di (Emperor Yan), Chi Di appealed to the Yellow Emperor, and the two emperors joined hands to kill Chiyou in Zhongji; Third, Chiyou attacked the Yellow Emperor as a soldier and was defeated and killed.
