I became famous for broadcasting my life as a social animal to different dynasties

After watching the video, Pan Jixun couldn't calm down for a long time.

Zhou Jinyu looked for some videos again. The river that burst its banks and changed its course most frequently in ancient times was the Yellow River.

Let’s take a look at what the Yellow River looks like now.

"Mr. Pan, let me show you the current situation of the Yellow River and see if it will be of any use to you."

Pan Jixun was very grateful: "Thank you, Miss Zhou."

Zhou Jinyu waved his hand: "No thanks, no thanks. Actually, I just moved my hands to play a video."

Other dynasties also became excited. Strictly speaking, the places where the Yellow River flows are all important cities or even capitals.

Every breach and flood of the Yellow River directly affects the stability of their regime.

Zhao Kuangyin even repeatedly asked people to record it carefully.

The people living along the Yellow River could hardly hide their excitement.

[The Yellow River is an ecological corridor connecting the Qinghai-Tibet Plateau, the Loess Plateau, and the North China Plain. The Yellow River carries silt from the Loess Plateau and forms a huge alluvial fan below Mengjin, Henan. The silt brought by the Yellow River forms the North China Plain under the joint action of the Huaihe River and the Haihe River.]

【Four thousand years ago, the three ancestors of the Chinese nation: Huangdi, Yandi, and Chiyou multiplied in the Yellow River Basin. The ancient capitals of Chang'an and Luoyang for 13 dynasties, Kaifeng for 8 dynasties, and Anyang for 7 dynasties were all administrative centers on the Yellow River.】

Qinghai-Tibet Plateau! Ying Zheng looked yearning, that must be the distant Qiang tribe.

Plateau means that the terrain over there is extremely high?

If our Qin soldiers arrive there, will they be unable to adapt? If they are not able to adapt, their combat effectiveness will inevitably decline.

In this case, there is no need to fight, and you will only suffer heavy casualties.

Ying Zheng secretly said what a pity.

Liu Bang's eyes lit up when he looked at the Qinghai-Tibet Plateau. What a huge area! What a vast expanse of land! I really want it!

But I also know that my current strength does not allow it.

Although Liu Che was jealous, he knew it was unrealistic to conquer this land, so he could only comfort himself: After all, this is the territory of the descendants of the Han Dynasty in the future! It is almost like our ancestors also have it~~

Li Shimin: "Look! Look! Chang'an is the ancient capital of 13 dynasties! So why don't people in later generations use it as their capital?"

Zhao Kuangyin: "Kaifeng!! My great Kaifeng!"

Kublai Khan: "The Central Plains region is truly blessed by nature."

[However, the lower reaches of the Yellow River have been recorded to have breached their dikes 1593 times, an average of once every three years, and there have been eight major diversions.]

[Every time the Yellow River changed its course, the people could no longer make ends meet, uprisings broke out, and the foundations of the dynasty were shaken.]

【Those who are good at governing a country in all dynasties must first control water. As the saying goes, "When the Yellow River is calm, the world is at peace."】

The people looked bitter. Who would want to be like this if they couldn't survive?

Someone noticed that the Yellow River flooded at a certain location on the map, but it bypassed a certain location. They were surprised and asked, "What is that place? The flood didn't reach that location?"

A well-traveled merchant took a closer look and clapped his hands: "That's where Mount Tai is!"

Everyone suddenly realized: It turned out to be Taishan!

The people living around Mount Tai straightened their backs even more: This is our sacred mountain, as long as Mount Tai is there, there will be no floods!

Tai'an Mountain means peace all over the world! !

【Five of China’s eight deserts and four sandy lands are in the middle of the Yellow River. The Yellow River is damaged in the lower reaches, sick in the middle reaches, and the root cause is the silt.】

Pan Jixun stood up suddenly. Is this the reason why the Yellow River frequently bursts its banks and floods?

Deserts, sandy land, Loess Plateau, every time the Yellow River flows through a place, it will carry a large amount of silt. The silt is deposited again and again, and the riverbed gradually becomes higher and higher, and slowly, a river on the ground is formed!

With a large amount of water, the river can easily burst its banks and flood! !

Sure enough, the fundamental problem of controlling the Yellow River is silt.

It is obviously unrealistic to use manpower to dig, so how did later generations deal with it?

Pan Jixun didn't blink.

[The Sanmenxia Water Conservancy Project was built on the Yellow River, but after only one and a half years of operation, 15.3 billion tons of silt had accumulated in the reservoir.]

[The silt formed a sand bar at the mouth of the Wei River, flooding both banks of the lower reaches of the Wei River and causing salinization of the land. Soon after, the Yellow River backflowed, seriously threatening the Guanzhong Plain.]

Pan Jixun sighed, it seems that the silt of the Yellow River cannot be blocked indefinitely.

Ying Zheng frowned. The backflow of the Yellow River would cause the water level of the Wei River to rise, and Xianyang would be in danger.

【Later, the Xiaolangdi Project was built downstream of Sanmenxia. This time, the experience and lessons of the Sanmenxia Project were fully learned. Xiaolangdi not only ensures flood control downstream, but also regulates runoff under the premise of reducing siltation. Xiaolangdi has raised the flood control standard of Huayuankou downstream from once in 60 years to once in 1,000 years.】

[There are also many water conservancy projects built in the upper reaches of the Yellow River, which form a system of coordinated operation of water conservancy projects, such as sediment discharge and flood discharge in the lower reaches and flow regulation and water storage in the upper reaches.]

Pan Jixun’s face turned pale. So many water conservancy projects!

Under the current conditions, it is simply impossible to accomplish.

All dynasties also shook their heads: It can’t be done!

Even if we knew the reason why the Yellow River flooded and burst its banks, it would be impossible to carry out large-scale water conservancy projects like those in later generations.

Even if the whole country decided to build it, what would the material be? The solid dams of later generations could not be made of mud!

Even if we take a step back and say that we have the materials, who will repair it?

Recruit the people to build it?

I’m afraid that the dynasty will be overthrown before it is established.

The people were horrified. What if the emperor suddenly ordered forced labor to build water conservancy projects? !

Zhuge Liang pondered: The fact that water conservancy projects in later generations could be built one after another shows that the court had ample finances, and that only with full support from above could lower-level officials feel at ease to do their work.

Moreover, there will definitely not be conscription and labor service in future generations.

Did they pay for the work? If they did, that would make sense.

No one will rebel for this. After all, ordinary people are all running around for a few pieces of silver.

Why take the risk of getting killed when there is money to be made?

The most important point is that the whole society must have developed to a certain level of technological advancement! It is easy to build these large-scale projects that seem impossible to them!

Now, none of these points are met.

Alas... Zhuge Liang sighed in silence.

[In addition to the construction of water conservancy projects on the Yellow River, the construction of the Three North Shelterbelt Project has effectively controlled the loss of sediment on the Loess Plateau.]

Pan Jixun's eyes lit up: Plant trees! The way to prevent sediment loss is to plant trees!

Is it that simple?

And this is something they can do right now.

Other dynasties also cheered up: Plant trees! Yes, they can do it!

But the people did not smile.

Plant trees? Forget planting trees, they even want to cut them down!

How can they reclaim wasteland without cutting down trees? Where will they get food without farming?

Not only was there no food, but they couldn't even pay the court's exorbitant taxes!

What if I can't pay? Sell my children?

Also, where can they find fuel to replace wood if they don't cut down trees?

Are we letting them starve to death in the summer and freeze to death in the winter?

Absolutely ridiculous!

People in later generations can plant trees because they will never have to worry about food and clothing.

They even use natural gas to burn fire, so there is no need to cut down trees.

But do they? They don't!

If someone doesn't allow them to cut down trees, then they can only cut them down for firewood...

After all, those who are barefoot are not afraid of those who wear shoes.

Moreover...the lyrics of the national anthem in later generations have been deeply engraved in the souls of every ordinary citizen!
