For example, Zhejiang water is named after twists and turns, and Jishui is named after crossing the Yellow River. There's probably a reason. It is unique to rivers. Some people say that rivers go down and flow with the ground. This explanation is too inaccurate. Which water does not flow with the ground? There is also a saying that the river is also called lotus, and the distribution of lotus essence is also cloudy. Just look at the author's explanation, which is extremely mysterious. I really don't know what he said.
According to the next speculation, since rivers have not existed since ancient times, there is no doubt that this water suddenly came up from the top of Mengmen. Where did it come from? Therefore, it is more appropriate to speculate that the river is not so much what it says as what it says. When it comes to its source, because of the change of terrain, don't say that Emperor Yao didn't make it clear, even those who advocated heavy source didn't make it clear. Emperor Wu of the Han Dynasty told Zhang Qian to find Heyuan, saying that he had met Petunia and Weaver Girl, so there was a saying that "how the water of the Yellow River moved out of heaven", which was even more bleak and unknown. Even when the Yuan Dynasty searched for Heyuan, it only found Xinghai, which is not clear.
It was not until the Qing Dynasty that I realized that it was under the old peak of Gadasuqi, and I finally figured it out.
Do you know where this water came from before the Qing Dynasty? Isn't it the meaning of a sentence that the dynasty wants to send someone to find it? Moreover, this water is not only unclear about its upper flow, but also unclear about its lower flow. Suddenly into the Bohai Sea, suddenly into the Yellow Sea, suddenly into the Bohai Sea, the biggest change is nine times. What is its initial flow path? I'm afraid no one can say for sure. Even at that time, King Yu Xia had divided the pollution of the river into nine parts, and no one knew which one was correct. Therefore, this Yellow River is always in doubt. River, what also. I'm afraid this ideal is good. But ask again, why is it always a question? I dare say again that the Yellow River did not exist in ancient times.
