Tell me with facts why people say that the Yellow River is the mother river.

As early as ancient times, the primitive ancestors of China lived and thrived in the Central Plains of the Yellow River Basin. In thousands of miles of the Yellow River Basin, our ancestors settled here because the climate here is mild and humid, the four seasons are distinct, and the water temperature conditions are superior, which is conducive to the growth of crops. In the early days of Chinese civilization, there were dozens of powerful dynasties, such as Xia, Shang and Zhou Dynasties and later Western Han, Eastern Han, Wei, Jin, Southern and Northern Dynasties, Sui and Tang Dynasties, Five Dynasties, Ten Kingdoms, Song and Jin Dynasties, and the core areas of their political and economic activities were also in the middle and lower reaches of the Yellow River. Many ancient classic cultural works reflecting the wisdom of the Chinese nation also originated in this area. Science and technology, invention, urban construction, literature and art, which marked ancient civilization, also came into being here. Therefore, the Yellow River gave birth to Chinese civilization and nurtured Chinese children. People often say that the Yellow River is the cradle and mother river of the Chinese nation, and this is its significance. The water quality of the Yellow River has three characteristics: first, there is less water and more sand; Second, the water resources are unevenly distributed in time and space, that is, the runoff area is unevenly distributed, and the runoff varies greatly from year to year; Third, the sources of water and sand are different. The sources of water and sediment in the Yellow River are different. Soil erosion refers to the damage and loss of water and soil resources and land productivity caused by external forces such as water power, gravity and wind power. In the history of China, people thought that the Yellow River was both a blessing and a curse. Therefore, the Yellow River has two nicknames: the pride of China and the pain of China. In historical records, this information first appeared in 602, until now. The direction of the river has changed five times. The current flow of the Yellow River is the result of the last change of 1897. The yellow color of the Yellow River is caused by the sediment in the river. Hundreds of years of sediment deposition have made the river flow on the surrounding farmland. Therefore, flood is a big problem for residents. There are many examples of villages destroyed by floods in history. In the history of China, the Yellow River had a great influence on residents on both sides of the strait, with both advantages and disadvantages. But in any case, the Yellow River has nurtured the Chinese nation and civilization, so China people call it "Mother River". The Yellow River is the birthplace of the Chinese nation, the mother river of the descendants of the Yellow Emperor, and the endless root of the tree of Chinese civilization! As the saying goes, "Huang Hefu in Ningxia is the best in the world", and the excellent natural environment in the Yellow River Basin has promoted the continuous development of Central Plains culture, which is praised by the world. The endless Yellow River water for thousands of years has nurtured hundreds of millions of acres of fertile land. "The wind blows low and the cattle and sheep are low" is the core birthplace of agricultural civilization for 5,000 years.
