To govern the two rivers is to govern the hearts of the people.
As the sun and moon change, the sediment in the two rivers will become higher and higher, especially the Yellow River, which has a lot of sediment.
The amount of sediment increases every year, causing the river bed to be raised and the water level to rise, eventually causing the Yellow River to burst its banks.
So far, in order to prevent the two rivers from bursting their banks, the imperial court has adopted the method used during Dayu's flood control period, that is, it is better to dredge than to block.
Dig ditches and dig deep channels to lower the water level and slow down the flow.
This method is naturally effective, but it treats the symptoms rather than the root cause. Every year the river is dug deeper, the sediment will raise the river again every year.
Lift once, dig once.
Lift once, dig once.
Doing this every year will only waste people and money.
Right now, there are still tens of thousands of people participating in the large-scale project of digging deep rivers, and they still exist in the form of corvee labor. The court will not pay them wages, and they even eat coarse grains and light rice every day.
Because this is something that every dynasty will do, and it is also something that must be done.
So whether it was the supervisory censor or Di Yan and others, they didn't pay much attention to it.
And this time.
After Xiao Yi started asking questions about politics in the southeast, some scholar-bureaucrats in the southeast finally raised the issue of governing the two rivers.
The suggestions in the memorial are actually just suggestions that the imperial court should pay attention to it and that His Highness the Prince should pay attention to it.
As for specific suggestions for regulating the Yellow River, they are still the same.
"In the lower reaches of the two rivers, sediment is increasing every day, causing the river bed to be raised. It's like this."
Xiao Yi directly explained the reasons for the rising water level of the Yellow River in front of the bachelors of the Imperial College, Hongwen Hall, and several ministers of the Sixth Ministry.
"Because the upper reaches are the Hetao land and the Loess Plateau."
"One of the reasons why the Yellow River is called the Yellow River is that the water of the Yellow River contains a lot of yellow mud."
"This silt slowly accumulates underground in the river channel, which will slowly raise the river channel, causing the water level of the Yellow River to rise."
"Especially in summer, because of the increase in rainfall, there is more sediment in the Yellow River."
"If there are continuous heavy rains and flooding, places like the Yellow River will inevitably burst their banks, causing floods to the people on both sides."
"Fertile fields have been flooded, houses have been washed away, there is no stable place to live, and there is no harvest."
"This is a memorial I just received."
"After reading this, what are your thoughts?"
Everyone, look at me and I'll look at you.
Finally, Han Yu stood up and bowed: "Your Highness, I believe that from now on, the imperial court must treat the management of the two rivers as a major national matter."
"Without the trouble of barbarians in the north, the world will be peaceful from now on, and people will no longer have to worry about war."
"But every time the two rivers burst their banks, it was like the barbarians in the north blowing their horns, and the local people suffered greatly."
"Even if it's a relocation, how can we ignore such a large piece of fertile land and such a big place?"
"Besides, this is the place where our ancestors have lived for generations. How can we just move it just because it's a relocation?"
"If it could really be relocated, the local people would have moved away over the years."
"Therefore, controlling floods in the two rivers should be equally important as strengthening maritime trade."
"If the floods in the two rivers are controlled, there will be a lot more farmland in Daqian, and the people near the two rivers will be able to live and work in peace and contentment from now on."
Han Yu was the first to stand up and support him, but to be honest, he didn't have any good suggestions.
There are specialties in art, and what he is good at is writing poems, not treating floods.
Xiao Yi nodded.
Then, someone else stood up and said that Han Yu was right.
Saying it means not saying it.
To sum it up, that’s three words.
Me too.
However, Xiao Yi still praised him.
Just because the other party has not put forward effective suggestions, we should not discourage the other party from making suggestions, right?
If so, who will give advice in the future?
Besides, such officials are actually more useful because they are on Xiao Yi's side.
If the water is clear, there will be no fish.
The court still needs some people who can flatter themselves.
One can imagine.
It is unlikely that Xiao Yi would hear some useful suggestions on controlling floods in the two rivers from these ministers and bachelors.
Therefore, he planned to hold small classes and let people record his thoughts while broadening the horizons of these people.
how to say.
There is still time now, but later on, if I don’t have time, I may not have the same effect as today if I want to teach such a small class.
It's better to say all the things that come to your mind and let others sort them out.
When the time comes, hand it over directly to the Minister of Industry and let him come up with a solution, and then ask people to find talents to control the floods in the two rivers, promote them, and let them manage it.
The most important task of the Crown Prince is naturally to oversee the country, which is to appoint people on their merits, but also to enable everyone to bring out their best talents, so that they can be worthy of their position.
“If we want to control floods in the Yellow River, we must first understand why floods in the Yellow River occur every year.”
"Gu Yi said at the beginning that the sediment raised the river channel."
"Then why is there silt that raises the river channel?"
"Because there is a loess plateau in the upper reaches of the Yellow River. The river water washes away the soil."
"This is the biggest reason why floods in the Yellow River appear every year."
"If we want to control floods in the Yellow River, we must find ways to prevent soil erosion in the upper reaches of the Yellow River."
"If you want to prevent soil erosion in the upper reaches of the Yellow River, in addition to widening the river channel and reducing the erosion of the Yellow River, you can also plant trees to prevent wind and sand."
"This may be a long-term major project, and it may not be effective in a year or two, but if we persist and let the upper reaches of the Yellow River be covered with lush vegetation on both sides, the erosion of water and soil will naturally be reduced a lot. .”
"Here's a solution."
"Another option is to use water to attack sand and build more reservoirs in the upper reaches. Before the rainy season arrives, water can be released to wash away the sand, directly washing away the sand in the Yellow River channel and rushing it to the coast of the East China Sea."
"If a water reduction dam is installed, the role of the water reduction dam is to better reduce the flow of water, and it can also better control the water volume of the two rivers."
“During drought, water is released for irrigation, and during rainy season, water is reduced to prevent floods.”
"This is also a way."
"As for deep digging of rivers, we can only say that it treats the symptoms but not the root cause. Every year the rivers are lifted up by sediment, and manpower, financial and material resources are spent every year to dig out the sediment."
"It must be a waste of people and money, and it must be cured for a while, but not for a lifetime!"
As Xiao Yi spoke, he took a charcoal pen and started drawing on the white paper on the wooden railing.
In this way, the ministers and academicians can more intuitively see the way to manage the two rivers.
besides.
Naturally, canals were also built.
It is better to block than to open up.
It would also be good if more branches could be opened downstream to achieve a diversion effect.
