The back garden is crowded with people, and the park is not far behind.

Today, Xu Linhai's lecture was placed on the stage with the best scenery and the most open scenery in the park. Dozens of tables were set up under the stage, and there were many new scholars and court officials in civilian clothes, and there were hundreds of scholars sitting or standing around them.

Tan Yin saw Li Zheng at a glance and greeted him in the air, Li Zheng was stunned, and seemed to be very surprised.

When Tan Yin and the others arrived in the garden, they learned that the previous few new science and technology scholars had already talked about it, and the final finale was this new science champion.

The two followed Lu Da to see Lu Yin, and sure enough, Zheng Xi and the other classmates were also there, Lu Qing glared at Lu Yin fiercely, it turned out that her sister was used to betray, Zheng Xi smiled at her, but Lu Qing didn't give him a good face.

Everyone was waiting for the final finale, and in the thunderous applause, Xu Linhai appeared on the stage, Tan Yin and Lu Qing looked at each other, good guys, this is the corner!

The topic of Xu Linhai's lecture today is the control of the Yellow River. The Yellow River flows from west to east, stretching for thousands of miles in the territory of Jokhang, and flows into the sea along the old road east five hundred miles north of Shangjing, half of which is now located in Dajing. In recent decades, due to several breaches, the Yellow River was diverted to the south to form the South Road. The flooding of the Yellow River has been a disaster for many years, and in recent years, it has broken out frequently, and there are endless disputes inside and outside the imperial court. No one has an opinion on whether to deal with the floods of the Yellow River, but they are divided into two factions on how to deal with them.

One faction of opinions should dredge the northern road, let the Yellow River flow into the sea along the old road, and prevent the embankment from bursting, which will cause a lot of disaster, but opponents believe that this will allow Dajing to easily invade the Jokhang along the northern road, Shangjing is located in the plain, there are no mountains to rely on, it is the land of the four wars, so that the Jokhang is more vulnerable to invasion.

Another school of thought is to block the northern road and strengthen the southern road. However, because the river is shallow and deep, the river often overflows, flooding the surrounding farms and fields, and the people are thousands of miles into an ocean, and the people are killed and injured countless times, and the people are not able to survive.

The two factions have been arguing endlessly, and there has been no conclusion for decades since the founding of the People's Republic of China, but the flooding of the Yellow River is getting heavier and heavier, which has affected the security and stability of Shangjing and its surroundings.

Xu Linhai took the stage to talk eloquently, he first responded to the lectures of the previous new science and technology scholars, and said: "There have been new science and technology scholars who have talked about the general trend of the world before. As we all know, there are two strong enemies in the north of Jokhang, Dajing occupies the northeast and Daxia occupies the northwest. The great victory of the battle of Zhenbei Hou Xixia has made the pressure on the northwest drop sharply, and it has also been connected with the Western Regions, and some horse farms have been built, and there are tens of thousands of good horses, among which the benefits are already known to you, I will not say more. However, with regard to Dajing in the north, the opinions of the government and the opposition are not unanimous. Although Dajing harassed us from time to time and penetrated deeper and deeper into our borders, some people believed that it had not yet fully moved south, and that its military strength was very strong, and that our DPRK did not have an advantage, and could not be carried out at the same time as the two countries, so it was necessary to give us some silver as before. There are also some people who think that the ambition of the wolf son of Dajing has to make inches, and he has long been not satisfied with the silver of these years every year, and sooner or later he will come to invade Dazhao, and he needs to take precautions as soon as possible. Both make sense, and they need to be prepared for danger in times of peace and be flexible. ”

"But what I'm talking about today is even more crucial, which is that the control of the Yellow River is extremely important to resist the Great Jing. There are two factions of opinion on the control of the Yellow River, and there is no good countermeasure, and it costs countless taels of silver every year, while the flooding of the Yellow River is getting heavier and heavier. On the surface, the Yellow River governance is based on which plan has more advantages than disadvantages, but in essence, it is how to view the people as the foundation of the state and the foundation of the country. ”

Everyone below was shocked when they heard this, and they listened even more attentively.

"Today, I think you have understood that the fundamental problem of controlling the Yellow River by strengthening the southern road will not solve the fundamental problem at all, and our court has spent hundreds of thousands of people and countless money on the south side of the road, but it has not improved at all, but it has affected the safety of Shangjing and the lives of the people. The side that opposes the construction of the North Road is nothing more than that Dajing will attack Shangjing along the North Road smoothly, and the injuries caused by the Dajing raid are more serious than the floods, so I will talk about it today.

People who hold this view simply believe that the Yellow River is a moat, easy to defend and difficult to attack, and if the Yellow River is held in danger, it will not be easy for Dajing to attack it. Then I would like to ask you to consider, the first emperor sent 100,000 soldiers to build the Great Wall to resist the Xiongnu, these Great Walls were still in the early Han Dynasty, but did they really block the Xiongnu? In the end, it relied on the huge wealth accumulated by Wenjing Zhizhi, the eloquence and strategy of Emperor Wu, and the desperate killing of generals such as Wei Qinghuo and Li Guang to keep the Xiongnu out of the Central Plains. In the 100th year of the Three Kingdoms, Shu was at risk according to Bashu, and Dongwu was at risk according to the Yangtze River, which was wider than the Yellow River, but it really prevented Cao Wei's army from dominating the world? After the Eastern Jin Dynasty crossed to the south, the north and the south were divided for nearly three hundred years, and the Northern Dynasty finally dominated the world, and the Yangtze River could have preserved the cultural context of the Southern Dynasties?

"Mencius said: 'If you enter, you will not be able to get home, and if you go out, you will be invincible to foreign patients, and the country will perish.'" What really protects the peace of the country and the people is never natural danger, nor is it the strength of the soldiers and horses, but the prosperity of the country and the strength of the people, and the unity of the whole country. ”

"The Yellow River has been plagued by natural disasters all year round, the people have been displaced, the population has withered, and the surrounding areas of Shangjing are no longer prosperous. The people do not want to stick to this place, they don't even keep their homes, will they still defend the country? The king regards the people as mustard, and the people regard the king as an enemy. Ignoring the people, losing the support of the people, and worrying about the country no matter how thorough it is, it will still lead to ruin. ”

Many people raised questions about this, and he answered, explained, and even refuted them one by one, and expounded on how people are concerned about how to make the country rich and the people strong, and how to work together from top to bottom.

When he finished speaking, everyone seemed to be still immersed in it, savoring the taste, and soon reacted, and he was responded by thunderous applause and cheers.

Tan Yin remembered that her father was once indignant at the trouble of the Yellow River, and directly accused the court of ignoring the people. If he was in the audience today, how excited he would be to hear these remarks.

Seeing that this person on the stage was radiant and confident, everyone in the audience yearned for him to worship him, Tan Yin had to admit that this person was really extraordinary.

It's just a pity that although the rose is beautiful and fragrant, it is arrogant and prickly, and ordinary people can't hold it.
