Live broadcast: Ancient people accompany me to make up lessons

Everyone has seen how the high loess slopes turned green.

It is the strong support of later generations of governments, the research and exploration of scientists, and the joint efforts of every ordinary person. Planting those acres of green plants was as difficult as building the Great Wall, but they gritted their teeth and actually planted these green miracles on loess and even desert.

The greenery everywhere makes the former working people feel the same way.

They are Guizhou heads, dirt-legged people digging in the fields, but they are also human beings. Knowing that building river embankments is hard work, they still do it, and they are always grateful to their parents and officials who helped them build temples and erect monuments.

They know that it is the earth under their feet that feeds them and the Yellow River that nourishes them. They also want to see their homeland become better, with clear river water and green ground.

I lament the hardships faced by farmers in later generations, and also envy the imperial courts in later generations who are really doing practical things. The economic and livelihood of farmers will be taken into consideration by those experts.

Those who have had life experience know the administrative situation in their own place very clearly. It is not easy to be blind and less exploitative when sending officials to collect things every year. Where can I find someone who squats down to teach people the law? Seeing the big from the small, it is conceivable that the officials in later generations will be very different from them now.

The lucky questioner, Zhu Houcong, was also in a heavy mood.

It is known that a variety of trees can stabilize water and soil and reduce land desertification. However, if the Ming army on the border did not farm on the spot and relied on grain transportation, the grain and grass consumed in the transportation would not be a small amount every year.

He could only try to plant trees while farming. He had written down all the Pinus sylvestris and other plants that appeared on the sky. He could draw their appearance when he looked back. He could find someone to look for them, and then find a way to cultivate them. He could discover them. Some seedlings that are good at farming would be even better.

This question is over, and the real No. 1 Xiao He is about to begin.

Although he knows that the anchor is not a goddess, but a little girl from later generations, Xiao He, like most people, still has respect for the anchor who imparts knowledge to them: "I want to ask the anchor, can you tell me in detail about the other two projects of the Three Gorges Project? ?”

[After taking a small look, I saw that it was Xiao He from the Qin Dynasty, which was a bit strange.

"The entire Three Gorges Project is quite big. Let's see if I can make a documentary about it tomorrow."]

Xiao He: "Thank you, host."

The videos played by the host generally have a lot of interesting information. In terms of look and content, documentaries are better and more detailed. No opportunity is wasted, which is good.

After Xiao He finished, Cao Shen, the second lucky audience member, thought for a while and asked: "The Yellow River has been well managed, why not fish out the sediment hanging in the river?"

Others were also curious, yes, why not just dig out the sediment in the river?

For them, this would definitely be a waste of time and money, but with the big boats on the river in the future, it shouldn't be a problem to catch some sand.

["Technically speaking, it is not impossible to dig out all the sediment in the Yellow River, but the cost is too high and it takes a lot of time." Xiaoxiao had thought about this problem before, but was later laughed at by her parents. Sure enough, he is a junior high school student.

"The river has been hanging for many years. The river channel and river bed are formed in the long-term evolution and are in dynamic balance. The action of external forces will affect the stability of the river and may cause the embankment to break. To cut the river bed, we can only rely on the force of nature. , use water to wash away the sand, and it is safe to cut slowly.

Moreover, the sediment of the Yellow River has been deposited for thousands of years, and it still carries 16 billion tons every year. How to deal with so much sediment and where to put it is a big problem. Therefore, we still choose to stabilize the water and soil at the source and build reservoirs and power stations in the middle to comprehensively manage the Yellow River. ”]

None of these ancient dynasties has yet to compete with the Yellow River. In the end, they can only dredge the river channel and raise the dams. At most, they can find ways to change the course of the Yellow River. Once they hear the anchor's explanation, they will understand.

However, Liu Che felt that since he had at least lost more than two thousand years of sedimentation at this time, it would not be a big problem for future generations to come to him to dig sand and dredge the river bed.

Cao Shen nodded, thinking that this was the truth. The hanging rivers in later generations were so high that a breach of the embankment was no joke.

"Who is the lucky audience number three, Lu Pheasant?"

Liu Ji: "My friend, the magistrate who is new to Pei County, is also named Lu."

Xiao He nodded: "In a few days, Mr. Lu will officially move into his new house. We should invite the county magistrate and the wealthy people to have a drink."

The Lu family, who were new to Peixian County, were busy every day. Lu Pheasant and his sister sat in the room, looking at the sky through the window. They did not expect that they would be lucky enough to be drawn.

Lu Yu was also happy for her sister. The little girl was happy to ask her sister what she wanted to ask.

Lv Zhi, who was also not that big, thought for a while and bowed to Tianmu seriously: "Looking at Tianmu's figures, the water of the Yellow River is still not enough for many provinces along the coast. How to solve this problem?"

In fact, she wanted to ask about the story of Niu Yuqin, the hero of desert control, but after thinking about it, it became clear. Later generations also built a desert control exhibition hall in her name. Sure, it seemed like she didn’t need to ask any more questions.

She didn't have paper, and she didn't have much pen, ink, or cloth to record. She tried her best to memorize the pictures and data posted on the canopy in her mind. The population of future generations will require a lot of water just to grow food. Planting trees also requires watering, and what they call industrial water.

Compared with the Yangtze River in the south, the water in the Yellow River is indeed not much. It should be difficult to achieve just by regulating water distribution. So she wanted to know if there would be other ways to solve the water problem in future generations.

"In addition to efficiently utilizing the Yellow River, we also have a project called South-to-North Water Diversion."

Xiaoxiao remembered that there should be related videos in his favorites, so he found them and showed them to them. "Wait a mininute."】

Ji An was silent, not surprised that Queen Gao asked such a question. Regardless of her political stance, no one can say that she governs the country poorly.

[No one speaks in the video, just different maps and text giving information.

Different colors divide the current land into different regions. The water resources data in each region are significantly different, with the northeast and northern regions accounting for the lowest proportions.

"The Yellow River, Huaihe and Haihe river basins account for 40% of the country's cultivated land, but only 8% of their water resources. How to transfer the excess water from the south to the north?"]

Everyone also remembers that when comparing the Yellow River and the Yangtze River, the huge difference between the two rivers can divert excess water from the Yangtze River to the north, which will indeed greatly alleviate the water pressure in the north.

The people of the early Tang Dynasty, who had just experienced the late Sui Dynasty, shuddered and couldn't help but think of the words "digging canals".

Seeing future generations manage the Yellow River, it was very painful to plant trees in the yellow sand all over the sky, but they would also be happy for future generations when they saw the green everywhere later; but if they had to dig canals to divert water, it would really arouse painful memories.

Li Shimin, who was still cleaning up Yang Guang's mess, comforted himself: "People in future generations will probably not dig canals. The terrain in the north and south is different. How deep can this river be dug? It will take a lot of work to reach the north."

According to the situation where they have to plant a tree and help the people consider how to develop cash crops, they should not be able to do Yang Guang's work.

[“In 1952, the great man first proposed the grand idea of ​​‘South-to-North Water Diversion’. After decades of research, in 2000, three routes were identified: the central, eastern and western routes.”

The map zooms in, and lines of different colors begin to move north.

"The eastern line starts from the Yangzhou Jiangdu Water Conservancy Hub and ends in Tianjin; the middle line starts from the Danjiangkou Reservoir on the Han River and ends in Beijing; the western line starts at the Yalong River and is transferred to the upper reaches of the Yellow River."

The map was drawn to the Han River and the project started to be displayed from the center line...]

"Diversion of the Yangtze River to the Han River, yes, is to ensure that the water in the lower reaches of the Han River is not troubled, so that the water of the Han River can be diverted northward..."

"Raise the Danjiangkou Reservoir so that the water will flow northward. Isn't Beijing's land very low?"

"People have done that, so it must be very low!"

Li Shimin: "We still have to dig the river..."

Regarding the water diversion project, they also saw the topography of different places, saw the huge Shah River canal, and also saw that when there is a drought, this water diversion project will also urgently transfer water to alleviate the drought for Henan people.

Zhu Houcong understood why the anchors talked so much about floods. They knew that they couldn't solve droughts by diverting water from places with water.

Emperors who often want God to even out the water because of droughts and floods here: Although we are greedy when looking at this project, we still have self-awareness. Even if the anchor found out about this project and told them in such detail, if anyone really has the courage to repair it, then just wait for public complaints to spread.

The ancient water conservancy experts thought for a while and suddenly realized: "We have to cross the Yellow River all the way to Beijing!"

Su Shi first thought about building a water storage dam similar to the size of the Three Gorges on the Yellow River and continuing to divert water further north. But then he thought it was wrong. In this middle line section, the Yellow River is very flat, and there is no such gap to build a dam. Dam. Moreover, if the water of the Yellow River and the water of the Yangtze River are mixed, something serious will happen.

He wondered whether it would be like the Shahe Caodu, which could be erected to allow water to pass through. Even if a lot of water will be lost in the process, it is always easier to build a bridge. Even bridge construction is not easy.

Originally, many people were still wondering how much effort it would cost to dig a canal through the north and south. When they saw the Shahe River Crossing, they discovered that it was not just a matter of digging a waterway on the surface. When they reached the Yellow River, they had to dig a tunnel to cross the Yellow River from below.

Ancient people:…

You might as well dig a canal.

Even people who already have many filters for future generations will feel that it is too much when they see the pornographic project.

That's the Yellow River!

The awe of the Yellow River has been engraved in the bones of the ancients. If something happened, the Yellow River flooded the urban fields, or the river workers in charge of the project had an accident, they would feel numb just thinking about it.

I saw eight landslides, three edge protections, and finally it took more than six years to build the yellow pipe project. While I lamented that future generations would not change it overnight, I also wondered how they could make these pipes leak-proof.

It’s really scary. The water drawn from the south passes through the Yellow River. If it leaks, the water in this section of the river will immediately surge, and then without even thinking about it, the Yangtze River water and the Yellow River water will cause a huge flood.

Fortunately, after crossing the Yellow River, the waterway flows through dozens of cities and counties along the coast, all the way to Laishui County, and then uses culverts to transport water to Beijing and Tianjin. There are no other more thrilling projects on the road.

When the video ended, they also put their minds down again.

It’s great that nothing happened to the Yellow River.

Deng Sui looked at this project with rare envy, and she wanted to sigh when she thought about the continuous natural disasters that followed the big man.

It was okay in the early Song Dynasty when no projects had been carried out, but everyone in the Zhe Zong Dynasty was silent and didn't want to talk. Because they also carried out a similar south-to-north water diversion project, but it was unsuccessful.

The Xianghan Cao Canal from Nanyang to Fangcheng, no one knows that the Song Dynasty also carried out such a large project without looking at the annals of Emperor Taizong of the Song Dynasty.

[A little addition: "The western route project is mainly located in the Hengduan Mountains on the edge of the Qinghai-Tibet Plateau, with an altitude of 2500 meters to 3000 meters. The construction is very difficult, and the project has always been planned and constructed. Okay, audience number , please speak. ”]

Ji An, No. 4, also learned from Huang Lao and ruled by doing nothing. He looked at the great projects of future generations on the sky and wondered whether the people in future generations would bear too much of a burden.

So he asked that too.

The corner of Liu Che's mouth twitched, and the memories of being rebuked by Ji An came to his mind again: "It's really what Ji An can ask."

[Xiao Xiao: "It doesn't seem to have any impact on us ordinary people. It's just that the places passing by the river may need to be relocated?"

She is from the south, and water diversion to the north will not go to her side. I really don’t know what the impact will be. It is also mentioned in the geography questions that the South-to-North Water Diversion Association will look up the information. 】

"How can there be no impact? Who will dig such a long river?"

"Looking at those rivers, they are not from the anchor's house. They have many people in the future, so maybe they didn't transfer many people?"

"They have been digging for many years, and there are so many people. It may be like the Jingzhou flood discharge area. It was completed quickly at different times."

Some people who had previously speculated on the identity of the anchor were very suspicious of her statement of "us ordinary people".

After all, even if her identity may be ordinary in future generations, as the anchor of their live broadcast, there is no way to tell that she is ordinary.

["When we look at the Three Gorges Project tomorrow, there should be a construction part, and you can see how the project is built."

It is clear that they still need to see it to believe it. Now that my legs are still wrapped and it is impossible to find a construction site, I will just watch the documentary.

"Next, audience member No. 4 can speak."]

Who is number four? Ma Zhen.

People from Shaoxing after the Eastern Han Dynasty stuck their heads out and asked: Is it Mr. Magong?

During the Eastern Han Dynasty, Ma Zhen, the lucky spectator No. 4 and the future prefect of Kuaiji, did not hold an official position at this time, nor did he build the famous Jianhu project on the Shaoxing Plain.

He has been to Luoyang and seen the Yellow River. At this time, the Yellow River and the surrounding areas were luxuriant with water, grass, and green trees. They were far less desolate than before the later generations of governance. The yellow sand in the water was not as scary, and the flow never stopped during severe droughts.

The young Ma Zhen was saddened by what this big river would suffer in the future, but he was also pleased with the actions and results of future generations' determined efforts to regulate the river.

"I would like to ask the anchor, how do you arrange so many projects, occupying fields and people?"
