Ancient books on river management

According to many records, Dayu governed the Nile. When we were in primary school, we all learned about Dayu's flood control in textbooks and didn't enter the house three times. At that time, I just learned the spirit of Dayu's water control, but I never thought about which river Dayu was managing. According to ancient records, the river governed by Dayu flowed northward when it was still valuable and was divided into nine tributaries. At first, many people thought that our ancient records in China might be our Yellow River, but after textual research, the flow of the Yellow River did not conform to the records. Later, it was found that the Nile was very consistent with the records.

There are few rivers that flow northward in the world, and the Nile is the only river that flows northward in the middle latitudes of the world. It is recorded in Historical Records:? There is precipitation in the north, and the nine rivers are broadcast in the north, which is the opposite river and enters the sea. ? This shows that the river governed by Dayu flows northward and is divided into nine tributaries, all of which go against the river and finally flow into the sea. The Nile is divided into nine rivers in the delta. During the 5,000-year vicissitudes of life, it is very likely that nine rivers will enter the sea when Dayu is harnessing the water. Therefore, it is very possible for Dayu to manage the Nile when he is managing water. From historical records? Against the river? Refers to the rivers in the against the tide, and the nine estuaries of the Nile are all against the current. Among the rivers whose altitude is lower than the delta, the river is affected by tides, which can affect hundreds of kilometers along the river. This is what the ancients called sailing against the current. The elevation of the Nile River in the delta is close to the sea level, and it is about160km from the bifurcation point to the China Sea. Jiuhekou is a typical reverse river, which further proves that Dayu may have managed the Nile from the beginning.

In the earlier Shan Hai Jing, it was also recorded that Dayu was in charge of water control, which proved that Dayu was in charge of the Nile. It was mentioned in Shan Hai Jing? The river flows from the northeast corner to the north, to the southwest into the Bohai Sea, and overseas, that is, in the west and north directions, into the Jishi Mountain led by it. ? This sentence cannot be explained if it is placed on a river in China. But if we put this description on the Nile, it will be very appropriate. There are white Nile and blue Nile in the Nile, and the white Nile is the mainstream, flowing through Lake Victoria, Uganda and Sudan, which is very consistent with the records.
