"It's well written, it seems that I haven't only read water conservancy books, but also field trips. △¢ "Zhu Yongxing carefully read the test paper of this candidate, and finally came to a conclusion, of course, referring to the professional discourse behind.

Chen Shaoyu and Zhang Huangyan took the test paper and took turns reading it, with puzzled expressions on their faces. Although they are not proficient in water conservancy, there are some things in this area that are different from the common law.

"Ten years, two or three million silver a year, there is no guarantee that it will be foolproof, this, this is inevitably some-" Zhu Yongxing had already made up his mind, but Zhang Huangyan couldn't find the right words to describe it for a while.

"It's a lot of money." Chen Shaoyu pondered for a moment and said: "However, if you wait a few years to destroy the Tartars, the country will recover, and the treasury will not be unable to take out this money." ”

"How many years has it been since I built a water conservancy?" Zhu Yongxing shook his head and sighed, "It's hard to go back!" Regardless of whether it is ten or twenty years, this is a major event that benefits all the people and benefits the future. Well, I still have a lot of questions, what about the candidate, call me to take a look. ”

"Hooray, there's something wrong with summoning candidates here, right?" Zhang Huangyan advised: "It's better to choose a day and change it somewhere else." ”

Zhu Yongxing thought about it and said with a smile: "I still can't help it." You can have a secluded room next to it, so you don't let too many people see it, so it should be fine. ”

Zhang Huangyan smiled bitterly, glanced at Chen Shaoyu, and the two nodded helplessly and went out to arrange.

Since the Ming Dynasty was in the middle of Wanli, after Zhang Juzheng used Pan Ji to tame the river, there were few water conservancy repairs. Neglecting the construction of water conservancy facilities, depleting agriculture to catch fish, and indiscriminately deforesting have led to the destruction of vegetation and ecological disasters in the Central Plains of Northwest China. Shaanxi, Gansu and Shanxi all had a relatively strict desertification trend in the middle and late Ming Dynasty, and the northern part of Shanxi was even more flooded with voles, which directly led to the extremely large plague that spread across the country during the later Tianqi and Chongzhen periods.

Why not build water conservancy? The main reason for this is financial constraints. The struggle between the two major groups of civil officials and eunuchs. Now, the first difficulty remains, but it won't last long; The second problem is no longer zài. And Zhu Yongxing attaches so much importance to water conservancy, which also shows his confidence on the other hand.

Water conservancy projects are definitely a key investment project of the state in any era, requiring a large amount of money and a lot of labor. And, in case it costs too much. If the foundation of the country is shaken, the problem can be strict (Emperor Yang of Sui's Beijing-Hangzhou Grand Canal is an example), so this matter is the same as repairing books, you can hardly do it if it is not a strong country.

Kang Xiaosan can create a "prosperous era" after quelling the "Rebellion of the Three Feudatories", am I still worse than him? Zhu Yongxing's self-confidence told him that he would only be stronger than Kang Xiaosan, and the prosperous era would come earlier and be more deserved.

When Chen Huang didn't know why, he was led to a hut by the officials of the examination room. Zhu Yongxing was sitting there waiting for him, and falsely reported that he was a river official who was about to be appointed by the imperial court.

In this way, Chen Huang is not particularly nervous. Moreover, river officials have a common relationship with their profession, and it is easier for them to talk.

Speaking of Chen Huang, he is already twenty-seven years old this year. Since childhood, I don't like Bagu articles, but I study farmland and water conservancy books. He also went to Ningxia, Hetao and other places along the Yellow River for field investigations, and studied the science of managing the Yellow River. It is this hobby that has fulfilled him, otherwise, according to his age, he is a scholar, and it is very likely that he was forced by his family to go to Yingshi Manchuqing.

Judging by the manners and words. Chen Huang is an open-minded and cheerful person, that is, he is not as cautious as the scholars next to him, so only talking. Moreover, he soon began to speak freely, which was naturally because of Zhu Yongxing's encouragement and guidance.

"The river is tough. The task is arduous and difficult to return, and it is by no means a one-time achievement. If the Banzai Committee trusts the officials, works honestly, and is not afraid of slander, there is nothing that can be done. Chen Huang drank tea, smiled bitterly, and said: "If you look forward and look backwards, and are afraid of hesitants, it will be difficult to control the river." ”

"The river has been out of control for a long time, so naturally we can't rush for quick success, and someone must rise up to bear it. The imperial court has already thought of these. Well, looking at your test paper, it will take ten years, can you shorten the time? Zhu Yongxing understood what Chen Huang meant, long-term work needs a stable leadership, only the emperor's trust, can not be replaced frequently, can not be said to be appointed this year, as soon as I heard that the embankment has broken again, he will be replaced.

Chen Huang thought about it seriously and said: "If the funds are sufficient and the manpower is sufficient, it can be achieved in seven years." ”

Zhu Yongxing nodded and said, "Looking at what you said on the test paper, there are many things that are different from the old method of river governance, can you explain it." ”

"In fact, it's not all created by the small people, I have already discussed it with Pan Jitao." Chen Huang took his professional test paper and saw that there were circles on it, so he explained one by one: "The reason why the Yellow River is flooding is because the river channel is rising year by year, forming a river on the bank, so the river embankment is getting higher and higher. The construction of embankments to restrain water and wash the sand with water is to strengthen and raise the embankment and narrow the river channel, so that the water potential will be strengthened and the flow will be accelerated, not only will the new sand not settle, but the old sand can also be rolled into the sea. The riverbed must be deeper and deeper, and the river must be lower and lower, so that there will be no danger of the levee bursting......"

"Has this approach ever been practiced? The result? Zhu Yongxing felt that the principle seemed to be reasonable, but he still had concerns.

"Naturally, there is a successful experience, and Pan Jitao ruled the river four times during the Wanli period, which lasted nearly ten years." Chen Huang said with admiration: "Pan Gong was the first river official to know the nature of water, the second river official was already well aware of the importance of embankments, the third prime minister of the river, formed the idea of 'governing the river with the river, attacking the sand with water' and put it into practice, and when the fourth river official, Pan Gong formed his theory of river governance." After the governance of Pan Gong, the Yellow River and the two rivers were restored, the sand brush water was deep, and the Haikou was opened. ”

It's much more reassuring that way. Zhu Yongxing secretly breathed a sigh of relief, although the new theory is eye-catching, but such a major event as river governance would be too child's play if it was to be used to make it real.

"If you want to control the river, the first is to be academic, think about things carefully, and understand the root cause of the flood." Chen Huang was still unsatisfied, and continued: "If the officials who control the river have no intention and no skills, and only know that sand removal and dredging will cost tens of millions of manpower and millions of gold every year, but the riverbed is silted up every year, and more and more are collected, and it will make a situation where the river will collapse and not return to the river, and when the flood season comes, it will immediately come to naught. ”

Zhu Yongxing nodded and said yes, if you want to cure the root cause, you must make a comprehensive plan, based on the long-term, and just deal with it every year.

"What the gentleman said is subtle." Zhu Yongxing did not hesitate to praise and said with a smile: "It's just that no trees are planted on this embankment, only shrubs and weeds are planted, which is too absolute." Wouldn't it be better to plant fewer trees and more grass? ”

"Students have done field trips and it's better to plant grass than trees." Chen Huang insisted on his own opinion, "Although the roots of the tree have the effect of fixing the embankment, there is a lot of wind and rain when the autumn flood comes, the embankment soil is soft, and the trunk is shaken, and the embankment is easy to crack." ”

People have visited the field, and it is more realistic than they think! Zhu Yongxing smiled and said in a deep voice: "Chen Huang, if you are entrusted with the important task of controlling the river, can you have the confidence to cure the river root cause?" ”
