Generally speaking, people who do academic research have one common characteristic, or they can be said to be a quirk, that is, they are not good at socializing, ignorant, and cannot learn the communication skills of long-term and good at dancing.

Zhu Youlang knows this very well.

Therefore, when Chen Huang acted like this, Zhu Youlang was not only not angry, but was also overjoyed.

He believed that this was a capable person.

He lacks capable people, nor does he lacks ministers who are polite and law-abiding and timid.

"Chen Huang, don't be polite, hurry up and calm down. I want to hear your opinion on the Yellow River." Zhu Youlang said.

"Your Majesty, if you ask the people about the Yellow River, you can be considered as asking the right people. The people dare to say that in the world, if you talk about the Yellow River, no one can stand up to the people." Chen Huang did not stand up, and blew away without hesitation while kowtowing.

He was very respectful in his rituals, but his words were crazy and perverse - Ren Yan looked at Zhu Youlang nervously.

"Hahaha... OK, I want to see if you have real talent or nonsense." Zhu Youlang was amused by Chen Huang again.

"Please give me paper and pen," Chen Huang asked.

"Fucun, the four treasures of the study are served." Zhu Youlang ordered Ren.

"I obey the order." Ren Yan hurried out, took out the four treasures of the study, and handed them over to Chen Huang.

Chen Huang took it, put it on the ground, spread the paper, knelt on the ground with his knees, and skillfully drew a trend chart of the Yellow River.

"Emperor, the Yellow River originates from Qing, and forms a river in Gannan, with its source in Peacock River. The entire river can be divided into three sections: upstream, middle and lower. The upper reaches are from Peacock River to Hekou Town, Mongolia, and are 7,000 miles long. This section of the river is small, with a small drop, and is more likely to pass through the valley. The river water is clear, which is beneficial and harmless.

The middle reaches are from Hekou Town to Taohuayu, Henan, and the total length is 2,500 miles. This section has a huge gap, reaching 270 meters. The Yellow River divides the Shanxi-Shaanxi Loess Plateau into two, with large sand content, yellow and turbidity, so it is named after the Yellow River. This section has a large gap, and the Yellow River rolls down, but because of the canyon between Zhongtiao Mountain and Wushan, there is no risk of breaking the dike.

The downstream is from Taohuayu to the mouth of the Yellow Sea, with a total length of 1,500 miles. This section is formed by a large amount of silt, forming an on-ground dike river, which is also the easiest section to break, like Kaifeng City, which is located in this section. Emperor, no one has built dikes to protect the rivers in the lower reaches since ancient times, and the river water has been flooded many times, which has formed the current river channel. The grass people dare to assert that if this river is not cured, it will inevitably break even after rainy years."

Chen Huang first briefly explained the outline of the Yellow River, and then said: "Your Majesty, we can see from this that the harm of the Yellow River lies in the accumulation of mud and sand, which leads to poor river channels. Over time, this kind of above-ground dike river has been formed. Therefore, controlling the Yellow River is to control the Yellow River in the lower reaches, and controlling the lower reaches must control the mud and sand."

"Well, the 'The method of shaking the dike and shaking the sand' that Ren Aiqing wrote in the Golden Palace today is because of this?" Zhu Youlang nodded and asked.

He agreed with Chen Huang's understanding of the upper, middle and lower reaches of the Yellow River.

Not to mention anything else, the investigation and identification of the source of the Yellow River is completely consistent with the investigation conclusions of later experts and scholars.

You know, before this, there were many different opinions and no conclusions.

Chen Huang is so familiar with the Yellow River, and he can easily pick up all kinds of data without any stagnation. It can be seen that the Yellow River has penetrated into his mind. This is by no means the knowledge obtained from books. It seems that Chen Huang has indeed traveled all over the Yellow River.

"Yes, the emperor, the reason why the grass people have this idea is that Pan Jixun, the previous dynasty, used to rule the river with this law, was very effective; the second is that the grass people benefited from the inspiration of the middle section of the Yellow River. Please see, the middle section has a large gap of 270 feet, which is really 'the water of the Yellow River comes from the sky'. But why is there less silt in the middle section? Does the emperor know?" Chen Huang asked.

When Ren Shi heard Chen Huang's words, he really wanted to kick him in the butt: "Who do you think you are? How dare you ask the emperor? Do you think this is discussing knowledge with me?"

Ren Shi quietly looked at Zhu Youlang, and saw that there was no surprise on the emperor, and knew that the emperor would not have the same knowledge as such a crazy person, so he felt relieved.

"Oh, what you mean is that because of the large drop and the river flows very fast, there is less silt?" Zhu Youlang did not mean to blame Chen Huang, but asked in contemplation along his thoughts.

Chen Huang slapped his thigh with a "slap" with his right hand and said excitedly: "Well, that's the reason. Your Majesty, you are the soulmate of the grass people. By the way, Boya threw the piano and thanked the soulmate, right?"

His slap scared Zhu Youlang and said to himself: "What's wrong with this? Why did he slap his thighs open? Are you so excited?"

Ren Shi was so angry that he rolled his eyes: "Chen Huang, Chen Huang, are you a head or a meatball on your head, and you also have a cognitive voice from the emperor?"

"Chen Huang, if you hand over this Yellow River to you, how many years will you take to clean the river water?" Zhu Youlang ignored his rudeness, but looked at Chen Huang with a bright look and asked.

Chen Huang was not at all conscious of saying the wrong thing. When he heard the emperor's question, he said without hesitation: "Emperor, if you leave it to the grass people to manage, and if all the money and men are sufficient, the grass people will guarantee that the water of the Yellow River can be cleaned in five years."

"Hahaha... Chen Huang, you're so big of this." Zhu Youlang said with a smile.

"Not big, not big." Chen Huang shook his head and said confidently.

"If you talk about it, how to manage it? Is it just a shaving dike to rush the sand?" Zhu Youlang asked.

"Emperor, 'Principle of 'Containing the dike to control the desert, and damaging the dike to prevent the collapse from the distance', these eight words are the formula for the people to control the river." Chen Huang replied.

"Then I ask you again, have you only seen the harm of the Yellow River, but have you seen the benefits of the Yellow River?"

When Zhu Youlang asked, Chen Huang was stunned and did not answer. Obviously, he had never thought about this question.

"Control rivers not only requires preventing collapse, but also finding ways to benefit the growth of crops in the river basin. For example, in rainy years, all tributaries pour back into the river will naturally have a huge impact on the Yellow River embankment. But what about the drought year? Can the Yellow River water be introduced into the tributaries to irrigate the farmland?"

"Also. What I just asked is that it is not to stop breaching the Yellow River water. Didn't you hear it clearly?"

Zhu Youlang's questions were raised, which made Chen Huang stunned.

He really didn't think about asking like this.

Zhu Youlang knew that due to the limitations of history, it would be good that Chen Huang could have this insight, and he could not expect him to have more and more sophisticated theories.

So he pointed out: "To govern the Yellow River, it is not only a downstream section, nor is it just involving Henan and Shandong provinces. It is necessary to manage it from the source. For example, the upstream and middle reaches can plant more trees and green grass to prevent soil erosion. If the soil and water are not lost or less, then there will be less mud and sand in the downstream; for example, while building a dike, artificial lakes can be excavated in areas where drought is prone to dig up water storage, repairing sluices, storing water in the rainy season, and releasing water in the dry season. Wouldn't it turn harm into benefits?"
