First of all, the earliest hominids appeared in the Yellow River Basin. Humans live by the river, and the Yellow River is their concentrated residence, which has nurtured many civilizations, such as Lantian people, Dali people's culture and Yangshao culture.
Secondly, the Yellow River Delta is an influential plain with flat terrain and abundant water resources. The climate with four distinct seasons is conducive to human survival and residence. The early big cities and villages of the Chinese nation developed along the Yellow River.
Because a good environment is conducive to agriculture and lays a material foundation for the derivation and inheritance of civilization. A large area of yellow land provides fertile and soft land for dry farming. The climate in this area is also very regular. The rainy season is just the growing period of crops. Therefore, millet, which is suitable for growing in the loess area, has a short maturity and is easy to preserve, has become the main food crop in this period.
In addition, its flat terrain reduces the communication difficulties of primitive tribes and makes cultural exchanges possible. In the absence of information media in ancient times, immigration and war were the means of cultural integration. It was this war that merged two cultures in the middle and lower reaches of the Yellow River. Even Liangzhu culture in the Yangtze River valley has been integrated into the Central Plains culture, making the Central Plains culture, as the essence of many cultures, the center of China's early civilization.
But the most important point is that in almost all dynasties, the political, economic and cultural centers of China always existed near the Yellow River Basin. Furthermore, although ethnic minorities have entered the Central Plains in a long history, they still continue the culture and ethnic system developed from the Central Plains. And actively carry forward and inherit this central plains cultural thought. Under the influence of economic development and ideological culture, over time, the ancient culture of the Yellow River Basin has experienced its own long-term development and evolution, and absorbed the essence of the surrounding areas. Eventually it became the mainstream of China's early civilization.
