Through the study of geographical history, demography, and historical climatology, we know that Henan was basically a flooded swampland four thousand years ago, a paradise for wild animals such as elephants and rhinos, and it was sparsely populated, and the possibility of Dayu running to Henan to control water was very small. Because if humans lived in large numbers in the Henan region at that time, they either let the flood wash away or let the elephants throw away the shacks; they were either attacked by tigers, wolves, snakes and scorpions, or they were plagued by various plagues. This is also the core reason why there is no lack of Yangshao cultural sites and prehistoric ancient ruins in the area east of Luoyang.

The age of The Great Yu Zhi Shui
Through the latest molecular anthropology, archaeology, linguistics, genetics and other comprehensive disciplines, research shows that "the Huaxia people were first born in the Weishui River Basin more than 8,000 years ago, this group is the ancestor of the Huaxia people, they took the Weihe River Basin as the center, gradually spread to the Yellow River Basin, the Yangtze River Basin and other regions, and finally formed today's Han nationality."
The earliest Chinese agricultural tool "bone" excavated from the Baojiguan Taoyuan site
From the large-scale use of China's earliest agricultural tools "bone" by the ancestors of the Baojiguan Taoyuan site more than 8,000 years ago, which is considered to be a sign of the origin of Chinese agriculture; to the earliest faience pottery unearthed in China at the Baijia site in Xi'an, to the three most representative sites of Yangshao culture, banpo site, Jiangzhai site, and Yangguanzhai site concentrated in Xi'an at the same time, we can confirm that Shaanxi is not only the birthplace and center of the Yangshao culture, but also the only province in the country covered by the whole basin of the Yangshao cultural site, and the true birthplace and center of the Yangshao culture.
A half-moon-shaped cultural belt with the Wei River Valley as its heart
In prehistory, the Chinese ancestors mainly lived on the Taiyuan of the second-level ladder of Chinese geography, and the half-moon-shaped cultural belt with the Wei river valley as the heart was the indiscriminate place of Chinese civilization, and the Loess Plateau was its core. The discovery of nearly 10,000 Yangshao cultural sites in Shaanxi is enough to prove how densely populated Shaanxi was 5,000 to 7,000 years ago, accounting for more than half of the country's population. In the era of Yangguanzhai culture (Miaodigou culture), with the large increase in population, the competition and conflict between the Yandi and Huangdi tribes located in the Weihe River Valley intensified, and a small number of tribal refugees fled east to western Henan and the Huanghuai Plain area where life was difficult. The development of large-scale immigrants in the Shaanxi region to eastern Shaanxi was already in the early Zhou Dynasty. The chinese civilization was first born in Guanlong and then spread from west to east has long been a foregone conclusion, and the migration and spread of Chinese ancestors from west to east has continued for thousands of years, until the middle of the Tang Dynasty.

It can be confirmed that during the pre-Yangshao culture and Yangshao culture, the center of Chinese civilization was mainly in the WeiHe River Valley centered on Xi'an. In the Longshan cultural period, due to the influence of the Great Flood Era, the northern Shaanxi Plateau became the most brilliant center of the Chinese nation, especially around 4500 to 3800 years ago, as evidenced by the emergence of super-large and highly developed civilization sites such as the Shi'an ruins, the Lushan'an ruins, and the Zhaishan ruins. Because in this period, the northern Shaanxi region has lush vegetation, abundant water and grass, suitable rainfall, favorable terrain and geographical location, which can not only cultivate and graze, but also effectively prevent the invasion of beasts of prey and floods, coupled with developed civilization, it can be said that it is the most suitable for human survival.
The pottery excavated at the Banpo site was identified by Mr. Guo Moruo as the earliest writing system in China
Archaeological research has proved that under the case of only 20% overlap between Yangshao cultural sites and Longshan cultural sites in Guanzhong, the increase in Longshan cultural sites in northern Shaanxi is as high as 5 to 7 times. It can be confirmed that during the Great Flood Era, a large number of Yangshao ancestors in the Guanzhong region migrated to the higher elevations of northern Shaanxi and Longyou, thus temporarily transitioning the center of Chinese civilization from Guanzhong to northern Shaanxi. Since 3800, with the return of another climate season, the climate of the Yellow River Basin has gradually dried up, and it has entered the Warring States Era with a small number of states, and various tribes such as the Xia, Shang, Zhou, Yi, Barbarians, Rong, Di, and Yue have flourished in their respective human climate and geographical environments, and blended with each other, until 600 years later, the rapid rise of the Zhou civilization in Guanzhong and the unification of the world, this chaotic situation of states and countries was finally over. With the success of the Western Zhou Dynasty in eradicating various state tribes, the Zhou civilization expanded rapidly. Since the Great Zhou Dynasty established China's first true capital city in Xi'an, Hojing, Chinese civilization has truly entered a new era of history, and we have truly formed a convergent cultural cognition Chinese. It can be confirmed that the most core elements of our Chinese culture were basically born in Guanzhong and were finalized in Guanzhong in the early Western Zhou Dynasty. Guanzhong is China's geographical origin, historical origin and cultural origin, from the Tang Dynasty to thousands of years ago for a long historical period, the "Guanzhong standard system" has always been the core of Chinese civilization. Although there have been found in all parts of the country so far, and some sites are even extremely rich in connotation, this does not affect the historical assertion that Shaanxi is the source of Chinese civilization and the root of the Chinese nation; it does not affect the great influence of the Weihe civilization as a main source civilization on various forms of civilization in various places, whether from genes, language, writing, high-level ceremonial vessels, bronzes, palaces, civil buildings or costumes and the entire ideological system.
Yangshao cultural site centered on Shaanxi
In recent years, in order to compete for historical and cultural heritage, some regions have built many pseudo-cultural projects such as the Yellow Emperor's hometown, Xiadu, Shangdu, and the earliest China. What is even more absurd is that the Institute of Archaeology of the Chinese Academy of Sciences has set up a special project to go to Yanshi Erli in Henan to find "Xia Du", to Shangqiu to find "Shangyuan", and to anhui "Yuhui Village Ruins" to find the ruins of Dayu.
The Central Plains mainly refers to the Fenwei Plain, the Central Plains are centered on Guanzhong, Southern Jin, and Western Henan, and the east of Luoyang does not belong to the Central Plains in the historical sense
According to the rational analysis of general scholars, the occurrence of Dayu Zhishui should be mainly in the Weishui River Basin and the Fenhe River Basin of the Fenwei Plain, because it is the center of Chinese civilization during the Dayu period as the two major plains of the Daguanlong region, and it is also the most densely populated area in prehistoric China. The Fenwei Plain is not only the earliest Huaxia, China and central plains, but also has always been the core and representative of the Central Plains culture. In this area, there are a large number of legends of Dayu Zhishui in the Shaanxi Enyi, Hancheng and Yuncheng areas in Shanxi. Yiyi was originally the fiefdom of Dayu's father, Cang, and also had the "Three Passes Village", which is the origin of the story of Dayu Zhishui "Three Passes Through the Door and Does Not Enter". Hancheng was first called "Dragon Gate" in the prehistoric period, and Zhou Qin's Jin wen records mention Dayu twice, which seems to be not out of thin air. The Central Plains dialect refers to the Guanzhong dialect, which is now spoken in the Fenwei Plain. Guanzhong dialect as the earliest Ya dialect, as the official language of the five Central Plains dynasties of The Zhou, Qin, Han, Sui and Tang Dynasties has been passed down to this day, and I believe that Dayu speaks this dialect.
