The Yellow Emperor should have nothing to do with Yan Di. But it is said that they are cousins, and they come from the northwest of the Central Plains, that is, from the ancient Xiongnu area. Legend has it that there are more than ten generations of Yandi people, just like the Yellow Emperor. Yan Di and Huangdi are not individuals, but times and nations. It is estimated that Yan Di entered the Central Plains at least 500 years before the Yellow Emperor. Yan Di is a farming nation, while the Yellow Emperor is a nomadic hunting nation. Therefore, it is unlikely that the two ethnic groups are related by blood. Strangely enough, the archaeology of Xiongnu area has not found agricultural history, so it is more likely that Yandi people will enter the Central Plains through this area. Legend has it that Yan Di people have a good relationship with Huangdi tribe. They should have trade and trade. They were defeated in the war between Yan Di and Chiyou and took refuge in the Yellow Emperor tribe. Huangdi tribe was invited to enter the Central Plains. The people of the two countries defeated and killed Chiyou together and won the final victory of the war, so the Yellow Emperor entered the Central Plains.

However, there was a conflict between the farming Yan Di people and the nomadic Huangdi tribe. Finally, the Huangdi tribe defeated Yan Di people, gained political power and ruled the Central Plains. However, we have always said that the descendants of the Yellow Emperor are in front and the Yellow Emperor is behind, which shows that the number of Yandi people is far greater than that of the Yellow Emperor tribe. At the same time, because Yandi people are agricultural people, food is not a problem, and a large number of people are engaged in other social division of labor, so science and technology culture far exceeds the Yellow Emperor tribal civilization, and the Yellow Emperor tribe absorbs and accepts the Central Plains civilization. Therefore, the Chinese people still put inflammation in the first place.

During the Warring States Period, the civilization of Chu State was not quite the same as that of the Six Heroes of the Warring States Period in Central Plains. The tiles and clothes of the Six Heroes in the North like gray and khaki, and the State of Chu likes bright colors. This may be because during the war between Huangdi tribe and Yandi people, some Yandi people moved to the middle and lower reaches of the Yangtze River.
