Introduction to the Yellow River:

The Yellow River is the second largest river in China and the fifth largest river in the world. It originated in the Yuegu Zonglie Basin at the northern foot of Bayan Kara in Qinghai Plateau, and flowed through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shanxi, Shaanxi, Henan and Shandong provinces, and then merged into the Bohai Sea in Kenli County, Shandong Province. The total length of the main stream is 5464 kilometers, and the water level drop is 4480 meters. The total basin area is 752,400 square kilometers. The main tributaries are Baihe, Heihe and Taohe.

According to the study of geological evolution history, the Yellow River is a relatively young river. In the late Early Pleistocene, 1 15000 years ago, there were only some unconnected lake basins in the basin, each of which formed an independent internal water system.

Since then, with the uplift of the western plateau, rivers have been eroded and eroded. After the Middle Pleistocene of 654.38+0.05 million years, lakes and basins have been gradually connected, forming the embryonic form of the Yellow River system. It was not until the Late Pleistocene from 6.5438+million years to 6.5438+million years that the Yellow River gradually evolved into a big river from its source to its mouth.

Historical stories about the Yellow River:

1, descendants of Chinese people:

Yandi was the largest tribe in the Yellow River valley at that time. In order to expand their territory, the two tribes joined hands to defeat the Chiyou tribe in Zhuolu, and in the battle of Gu Quan, the Yellow Emperor defeated Yan Di again. The Yellow River basin experienced great fission and fusion, and the Yanhuang tribes gradually merged and assimilated other ethnic tribes. Finally, a multi-ethnic Chinese nation with the Yellow Emperor as its ancestor was formed.

2. The story of carp yue longmen:

Little carp jumped over the gate to Jackie Chan, regardless of difficulties and obstacles. If they can jump over, they can become Jackie Chan. Only those indomitable little carp can eventually become Jackie Chan. This story has also inspired the Chinese people to work hard for thousands of years. The ancients felt incredible about the formation of this natural wonder, so it is said that Dayu chiseled a canyon, so Longmen was also called "Meiyukou".

3, Dayu water control:

After inheriting the throne, Yu, the son of Gun, was appointed to manage water. Summing up my father's experience in water control, I changed the "blocking barrier" of Gun to "dredging the flow from high to low", that is, I used the natural trend of water flowing from high to low to dredge the congested streams, introduce the flood into the dredged rivers and depressions, and then connect the four seas, so as to calm the flood and make the people move back from the highlands.
