Legend has it that they came from the same tribe and later became the leaders of two rival tribes. Two tribes started the battle of Hanquan, and the Yellow Emperor defeated Yan Di. The two tribes gradually merged into Huaxia, which was called Han after Han and Tang after Tang.
Yan Di and the Yellow Emperor are also the ancestors of China's culture and technology. It is said that they and their courtiers and descendants created almost all the important inventions in ancient times.

The development of the Chinese nation is like this: during the Yanhuang period, the Yanhuang tribe was the most powerful, the Yanhuang tribe developed into the Huaxia nationality, and the Huaxia nationality developed into the Han nationality. Han people interact, collide, intermarry, unite and merge with other ethnic minorities, but at the same time they are different, forming today's multi-ethnic family-the Chinese nation.
In this process, Yanhuang-Huaxia-Han nationality has always been the main body, so Yanhuang became the representative of ancient Chinese people, and later became the symbol of Han nationality, and later became an important cultural symbol, even a symbol of the Chinese nation.
Some people say that the emphasis on Yan Huang stems from the anti-Qing revolution. That's good. However, since Sun Yat-sen put forward the idea of harmony among the five ethnic groups, the mainstream view has become "China people are all descendants of the Chinese people".
Later, this theory changed people's ideas and gradually became the knowledge of the vast majority of people. Yanhuang naturally became the "ancestor" of the Chinese nation.
Saying that Yanhuang is the "ancestor" of the Chinese nation does not mean that Yanhuang is the only ancestor, just as far as the mainstream is concerned.
The word "descendants of the Chinese people" should be understood as follows: This word only means that we China people are descendants of the great ancestors (including Chiyou) of that era represented by China people. To say that Yanhuang is "the ancestor of mankind" means to make it clear that we are the cultural descendants of Yanhuang.
