Live broadcast: Ancient people accompany me to make up lessons

["The new compact hybrid high-yielding corn seeds bred by Li Denghai have been promoted over a cumulative area of ​​about 12 billion acres, adding more than 1200 billion yuan in social and economic benefits to the country... and is known as the father of hybrid corn in China."

This already successful man is still busy every day, either in the cornfield or in the laboratory. Sometimes he also travels back and forth to the experimental fields in Shandong, Northeast, and Hainan. His daily life is busy.

He looks honest and simple, his eyes light up when he talks about his corn, his language is humorous and he uses the simplest words to describe his work. ]

The Hongwu Dynasty and the Yongle Dynasty were already thinking about how to go to sea to find this corn and potatoes. However, the Zhengde Dynasty and Jiajing Dynasty, which had a large number of private fleets, had banned the sea. The sea ban was established by their ancestors and had been for many years. They would definitely oppose it directly. There were a lot of people, and they were thinking about whether to directly spend money to recruit people to go out to sea to find these two crops first.

During the Kangxi period in the north, people who could already eat corn and potatoes thought about the large expanded leaves when they planted corn, and looked at the compact corn pieces facing up in the sky, with longing flashing in their eyes.

Dong Ruyi tugged on her parents' clothes and suggested: "Let's see which corns grow better next year when we plant corns, and pollinate them ourselves to raise different new corns."

They suffered from hunger and experienced famines, but they were lucky enough to survive. She doesn't like eating these rough, dry corns, so she also wants to turn them into corns that can be crushed softly in the hands of the anchor.

Although she is young, she still remembers the story of Niu Yuqin yesterday.

They are just ordinary farm girls. They can still farm at home. It is not a desert full of wind and sand. They can make the sand quiet. Why can't they also make corn varieties better from generation to generation?

The adults were silent and did not speak.

Of course, the whole family wants their yard to be filled with golden corn, but they don’t know how to do anything. What if they don’t pollinate it well and the grains are harvested?

Finally, the eldest elder in the family said that this matter cannot be done carelessly at home. It takes a lot of time to plant corn from generation to generation. We must talk to the village and see if we can do it. Let's find a way to do it together.

Xiao He, who had complimented Mr. Yuan two days ago that "the national scholar is unparalleled": I'm sorry, Mr. Yuan, it seems that the national scholar really has two.

Of course, the above is just a joke. I have the same admiration for Mr. Li and Xiao He. Both gentlemen are truly great people who work hard to make everyone in the world no longer hungry.

The first round of lottery draws in the morning is over, and the anchor has finished a paper. Can we show him the documentary about the Three Gorges?

[Of course Xiaoxiao also remembers this.

She didn't know much about Mr. Li, so she was very serious when watching. As a reward for Grandpa Li, she decided to cook the two corns at noon and never waste them.

After making her decision, she dug out the documentary about the Three Gorges and prepared to watch it while writing her English composition. 】

Students studying in different time and space: ...it’s so early, are you really not planning to take a break at all? Those of us who are studying look at the sky, and then see you studying seriously, we feel really panicked.

Although the teachers were eager to make a move and wanted the students to watch the sky screen again and again and write down their thoughts after watching it, they ultimately felt that it was a waste of time to multitask like this and let the students watch the sky screen honestly first.

Like Xiao He, other people in the Three Gorges area also took up their pens again to remember how it was built and how to arrange the relocation of the people.

Different music sounded again, and the blue sky and white clouds moved rapidly. Everyone has finally discovered that, except for those videos of a few minutes, everything they watch in the future will have music playing first.

[The music ends, and what is in front of the camera is huge, plump golden wheat ears, followed by a large flat wheat field with a red harvester running on it.

Based on the early morning activities of a small villager, the narration began to introduce Baizhou Bay and then the Three Gorges Dam. ]

"This red guy is cutting wheat!"

Unlike a planter that can be as tall as a person, the red machine that is harvesting wheat in the wheat field is so big that the person sitting in it looks like he is trapped in a small house.

The red machine moves smoothly, and the black rollers in front cut off all the wheat, and then separate the wheat straw from the wheat.

The footage is very clear, and even the separated wheat stalks and wheat ears are clearly distinguishable. Everyone can easily understand what this machine is doing.

Mo Weiwei said: "That was a seeder before. This one should be a wheat harvester?" There is one more thing that I want to ask the anchor for detailed drawings of.

Others thought the same thing, not only the big guy who was harvesting wheat, but also the golden, plump, distinct grains of wheat on the field, which were obviously improved and fine wheat seeds. They wanted to know even more.

[Thunder sounded, raindrops splashed on the yellow mud ground, and the rushing water quickly splashed on the shore.

"At seven o'clock in the evening on January 1998, 1, at the Weijia Wharf in Zhongbao Village, the Hezhen section of the Yanzhou Embankment, a strong piping surge occurred 40 meters from the bottom of the embankment, and the 100-meter embankment section suddenly collapsed..."

The surging water flooded downwards, easily covering the one-story small house, and also washed away the iron boxes on the roadside. At this time, there are still many people wearing only pants and shirtless bodies, carrying bags of unknown items and putting them on the embankment. ]

For those who have witnessed the horrific scene of water destroying dams, the flood captured by the canopy once again stirred up those memories of the past, and each and every one of them began to worry about the future generations on the canopy.

"The flood is coming, run quickly!"

"Why don't they run away from such a huge flood?"

"They seem to go to the water specifically..."

Knowledgeable people have already seen from the scene of just a few seconds that these men rushing forward carrying bags do not seem to be villagers. They are all capable and strong, and the muscles of the hands carrying bags are bulging. They looked like they were rushing forward without changing their expressions. Their expressions, steps, and behaviors were all too similar.

They don't look like loose civilians, but like organized, well-trained, and purposefully doing things...soldiers?

Thinking of this, many people shook their heads.

The soldiers in the disaster-stricken areas were there to prevent the people from revolting and to suppress them. There were soldiers there who were not equipped with weapons and rushed into the floods one by one with their shirts off.

[Wang Zhanping recalled the horrific disaster that year and laid incense in front of the portraits of his parents. The flood took away more than 40 lives, including his parents. ]

Many people in different time and space feel the same way. Every time there is a natural disaster, they, the largest number of ordinary people, are always the most seriously harmed.

There are also some people who are dissatisfied: "Only a few dozen people died. When has there been a disaster and some people don't die? What's the point?"

[Muddy water flows under Fangzheng Building, and red flags flutter.

"Also in 1998, not far from Yanzhou Bay, a river embankment breached, killing 1526 people, affecting a population of 2.23 million, and causing direct economic losses of more than 1660 billion yuan..."

People uniformly dressed in green clothes, green hats, and orange life jackets stood in rows in the water, looking determined. ]

Those who just complained that the flood was no big deal stopped talking. The deaths of more than a thousand people were certainly not taken to heart by these people. They were counting the economic losses and the number of people affected by the disaster.

Even if there are so many improved species in later generations, the number of people affected by the disaster is still large enough. The subsequent relief, arrangements, recovery... each of them is not a simple matter.

Officials with some financial knowledge have calculated that if they want to suffer so many disasters here, they may have to flood the capital directly. In later generations, there were only so many losses in a flood. Either the flood was too big, or many of their places were already very prosperous, or it was possible that their disaster-stricken algorithm was much less.

The people who had been guessing the identities of the people holding the bags before saw the uniformly dressed people in the water and discovered that they might indeed be the most unlikely identities they could guess.

But...how could it be a soldier? Why aren't they all running in the water? Disaster relief?

[Yangtze River Water Conservancy Commission, like the Yellow River Commission, many people here are also testing on different computers.

On July 2010, 7, Xu Weili, who was monitoring recent weather information, finished analyzing the data and saw that a heavy rainstorm was coming. After reporting the data, the national and Yangtze River basin flood control departments and hydrometeorological departments along the river, together with the Three Gorges Group dispatch center, immediately held an emergency video conference...

Men and women wearing different clothes sit in different offices, and they are all on a big screen, discussing matters together from different distances. ]

"Yellow River Commission, Yangtze River Commission, Flood Control Department, Meteorological Department along the River..." Writing down these different departments, Li Si also had a headache. In this future generation, hydrology alone will only need so many talents, and how many officials will they have? , how will future generations manage this?

Li Si was very envious when he saw them being able to conduct 'video conferencing'. This method can directly communicate with officials in different places and issue political orders immediately, saving enough time for the court to do enough things.

No wonder later generations of courts were able to manage countries so much larger than their own, Great Qin. These methods were really useful, so they had better wait for the Mohist paper to be made first.

There are many people who are as envious as Li Si. They already knew that the anchor's mobile phone can transmit sounds and pictures thousands of miles. Now I think about it, even with so many people in meetings all the time, the anchor's mobile phone should be able to do the same.

The more I think about it, the more envious I become, and I want to buy a mobile phone from the anchor. Or can I give the anchor a mobile phone as a lucky gift next time?

"It's great. It's going to rain heavily or flood. In the future, they will know in advance..."

Looking at the medium-term forecast on the conference PPT, not only the weather, but also the approximate peaks of water flow and floods in different river basins and different dates can be predicted.

"What is that news broadcast? Why are all those people at the water's edge?"

"Look at them all talking about the Yangtze River, as if they are telling us..."

[“The world’s largest hydropower station took the Chinese seventeen years from the beginning of construction preparations in 1993 to the completion and commissioning of the Three Gorges Project in 2009.

During the construction of the Three Gorges Dam, we not only conducted a large number of model experiments and geological exploration work, but also learned from the experience and lessons of dam construction at home and abroad..."

Zheng Shouren, an academician of the Chinese Academy of Engineering, recounted the past when he was building a dam. The colored water turned black and white again, and one after another young, middle-aged and even old people surveyed the water flow, carrying equipment with straw hats. ]

After watching it for a few days, everyone understands that the beautiful, colorful pictures are from the anchors now, while the blurry ones, or black and white pictures, were from them decades ago.

As long as you think about it, in just a few decades, things that were still black and white or immovable have become brightly colored, clear and movable. The speed of this development is shocking.

Someone said: "After graduating from East China Water Conservancy University, I heard that I learned how to control water. What this university teaches is amazing..."

Others were surprised: "They have so many majors in university, and they even teach desertification control. Have you forgotten the water conservation major?"

The man nodded and shook his head: "After all, it is water control..."

Regardless of time and space, the Chinese civilization was in the agricultural culture circle. Eating was the most important thing for everyone, and farming was the top priority.

The thing that most affects farming and daily life is undoubtedly water.

Almost every figure who is good at controlling water and helping the people is remembered by the local people. Dayu, Li Bing, Zheng Guo, Ma Zhen, Su Shi...

But they are not civilians, and they have access to educational resources since they were born.

But in future generations, such important water control knowledge can be learned as long as you pass the college entrance examination and go to university. The same goes for how to cultivate improved seeds.

Whether it is Mr. Yuan, Mr. Li, or those who worked on the Three Gorges, they all came from ordinary backgrounds and made real careers through study and hard work.

Some people also lamented that as soon as they graduate and learn professional knowledge, they can be assigned to places related to their majors. For more than 40 years of water control, the young people in black and white photos to the old people in color photos have always been around the Yangtze River. It is completely useless. It will be a waste of time, and this is how people use their talents.

In the Wang family in the capital during the Zhengde period, Wang Hua looked at Zheng Shouren in the sky. When he looked at his eldest son, whose temperament had not changed much for so many years, his old father clicked his tongue, feeling dissatisfied for the first time.

Wang Shouren had no objection to his father's eyes.

Also named Shouren, the descendants of Tianmu have been dealing with water conservancy from young to old, and the things they do are vigorous and beneficial to the country and the people. Compared with him, being a Jinshi and serving as an official in the capital is a waste of time.

He lowered his head and thought about whether he should go to the emperor and let him go somewhere else. Compared with future generations where everyone performs their duties and does truly meaningful and important things, what they do in the capital all day long is not worth it. He really felt that it was meaningless...

The dynasties with higher productivity were better. During the Qin, Han and Three Kingdoms periods with constant wars, ordinary civilians who had no food to eat and were living in danger looked at the civilians wearing hats, carrying burdens and digging soil on the sky. Wonder why they are so energetic.

Even the old women sitting by the haystacks, looking tired, drank water and went to work.

Obviously there are no officials to supervise their work...
