Chapter 26 Discussion of Current Politics
In the classroom of Luxi Academy, Mr. Chen He is teaching the students.

Chen He put down his book, and walked slowly with his hands behind his back: "Today, let's discuss current affairs. In recent years, the Yellow River has flooded many times, and the people have suffered untold hardships. His Majesty the Emperor wants to personally inspect the river to see the actual situation, so that we can formulate policies based on this." Strategies for controlling the river."

"About this strategy of river control, the princes of the DPRK and China are arguing endlessly. Some say that we should follow the methods of the predecessors, mainly dredging, and clean up the silt at the bottom of the river; Narrow river. What do you think about these two kinds of remarks? At this time, political discourse is also a compulsory subject in the rural examination, so you don’t have to be cautious, just speak freely.”

A student in the front row immediately stood up: "The Yellow River has always been treated by embankment and dredging. Why did the Shaoqing of Dali Temple narrow the river? Once the river narrows and the water level rises, won't the Yellow River be more likely to collapse in the flood season? What else is there to say?"

"Haven't your Excellency heard of beaming water to attack sand?" Another person disagreed, "This is the theory put forward by Pan Shaoqing. Narrowing the river channel will increase the water level, but the water flow will also speed up, so that the sediment on the river bottom can be washed away. Wouldn’t it be more convenient and quicker to clean up the river once and for all than to clean up the silt?”

"What's the point of managing the Yellow River once and for all? Naturally, it needs regular dredging and constant care. If the river is narrow, the flood will come first before the sediment is washed away. When the time comes, millions of lives in the middle and lower reaches of the Yellow River will be devastated, so what? Okay? It is recorded in the ancient books that Dayu used the strategy of dredging water to control the water. Isn’t it ridiculous that he didn’t follow the law of the sages, but came up with something like slashing water and attacking sand?”

The man blushed with anger, pointed at the other party and cursed: "Pedantic! Times have changed, how can we copy the methods of the predecessors? Building embankments and dams can be carried out at the same time as narrowing the river channel. When the river bottom sediment is washed away, the river bed If the location is low, the water level will naturally go down. You said you want to dredge it, but the imperial court clears the silt every year and the Yellow River floods every year, has it ever improved?"

"Hmph, following the established law, at least the situation won't be worse, not to mention that the last major flood of the Yellow River was eight years ago. As for the Shushui sand attack, I have never heard of it before. If it is really implemented, maybe this year's spring flood The Yellow River will collapse immediately!"

"You—unreasonable! I can't explain the truth to you!"

"Okay, okay, class discussion is about the matter. It's normal to argue with different opinions for a while, don't take it to your heart." Chen He came out with a smile to smooth things over, and turned around to see Gu Yunji who was smiling and silent, as if he had a plan in his chest. His heart moved, and he asked : "Do you have any good strategies for controlling the river?"

Gu Yunji stood up and said calmly: "Students have three strategies. In terms of time limit, they can be divided into near, middle and far."

There was an uproar in the hall: "The adults in the court only have two strategies when they are arguing. When he came, he said that there were three strategies. Could it be that he is talking big..."

Chen He became interested: "Oh? Then tell me."

Gu Yunji said: "The shortest strategy is to clear the silt at the bottom of the river and open up new channels to divert the Yellow River water. But as I said just now, the silt will be cleared this year, and the sediment will be deposited next year. The cycle is endless, so this strategy At most, it can keep the Yellow River safe for five years."

"The middle strategy is to narrow the river channel and deepen the river bed to accelerate the flow of the Yellow River so that the river bottom silt can be washed away. But this strategy also has shortcomings. Once the flood season occurs, if the river bottom scouring effect is not as expected, the risk of collapse will be increased. The risk. Not to mention that the sediment of the Yellow River flows down from the upper reaches. Even if the downstream is cleaned up, the problem of sediment is not solved, and the possibility of flooding of the Yellow River still exists. This policy can be guaranteed for 30 years.”

"The long-term strategy is to plant trees and afforestation in the Guanzhong area of ​​the middle and upper reaches of the Yellow River. In the land of Guanshan, there are few trees, and the soil is thick and loose. Once the wind blows, the sky will be full of yellow sand. In summer, there is plenty of rain, and the rainwater rivers wash the loess on the ground and carry muddy water. This is the root cause of the sediment problem in the Yellow River. To cure the Yellow River, trees must be planted all over the middle and upper reaches of the Yellow River, and the soil layer should be firmly grasped so that the rain cannot wash it away."

Speaking of this, Gu Yunji paused, and said slowly: "This matter cannot be accomplished overnight. It will take the continuous efforts of several generations to see the effect. This strategy can last for a hundred years." Suddenly, he accentuated his wording, His tone became heated, "However, if the three strategies go hand in hand, the water in the Yellow River will be clear, and it will be safe for thousands of years!"

His words opened up the past and the present, and put forward a bold and comprehensive theory, which shocked everyone's minds. Chen He was fascinated by listening for a while, and he didn't speak for a long time.

At this time, a student gave him a disdainful look, and said, "Your Excellency is so eloquent, must have been to the Guanzhong area, and personally surveyed the Yellow River?"

"I've never been there, I read the description of Guanzhong in the book." Gu Yunji nodded slightly.In his previous life, the geography class on the Loess Plateau had pictures, text, and even a documentary. The details were so detailed that people could see it with his own eyes. Books of this era can't compare, but that's all he can say.

The man sneered, "Then you're just talking on paper?" Then he stood up and said, "I'm from Guanzhong. According to what I've seen with my own eyes, Guanzhong is fertile and wild, with lush vegetation. It's not as sparse as you said. , you are just talking nonsense, and you are talking about short-term strategies and long-term strategies, which is extremely ridiculous."

Gu Yunji said unhurriedly: "The Guanzhong Plain is indeed called the Fortress Jiangnan, but further north, it is a plateau area. The mountains are rugged and vertical, the soil is loose, and there are few trees. There are more places like this in the middle and upper reaches of the Yellow River. Your Excellency Living in the Guanzhong Plain for a long time, it is normal to have never seen it."

"Hmph, as if you've seen it before?"

"I've seen it." At this moment, a lazy voice came from the corner.

Su Qi yawned, as if he had just woken up, stretched his waist, and said casually: "I have seen it. I used to go out with my father, and I went to the Guanzhong Plain and the plateau in the Guanbei area. It is exactly as he said, Large areas of loess, no dense forests, at most a few clumps of low shrubs. The local people live in cave dwellings. When it is windy, the yellow sand all over the sky makes it hard to open your eyes, and the clothes are full of water. It's sand."

Duke Dingguo is a military general who has been guarding the border all year round. It is not surprising that as his son he goes out with the army. Su Qi's words are highly credible.As soon as these words came out, the student from Guanzhong had nothing to say and sat down reluctantly.

After hearing all this, Mr. Chen He sized up Gu Yunji, feeling more and more extraordinary about him, his eyes sparkled: "When you go back, write your river control strategy into an article, remember to be clear and clear, and leave it to me in the next class. "

Gu Yunji nodded yes.

After school at noon, Gu Yunji returned to the dormitory after lunch, and saw Su Qi lying on the table fighting crickets, he walked over and said, "Thank you, sir, for speaking for me in class today."

Su Qi didn't even raise his head: "I'm just telling the truth, I don't mean to speak for you." Seeing the cricket in the bamboo tube turn over and fall on his back, he clicked softly and turned to look at him, "I saw it with my own eyes. Passing through the land situation in Guanzhong, I think the river control strategy you said is very reasonable, so you just said it casually in class, so you don't need to thank me."

After all, without caring about Gu Yunji, he went out again with the bamboo tube in his arms.
