Why is the Yanhuang era the source of China culture?

"Yan" refers to Emperor Yan, the same as Jiang Shuicheng (now Baoji City). "Yellow" refers to the Yellow Emperor, which is made of Jishui (now Wugong Qishui River in Shaanxi Province). Emperor Yanhuang was the ancestor of China. 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.

So now we often say that we are descendants of the Chinese people, which is the reason.
