Some people cry, some people laugh.

Zhang Xia has been upset by the sound of firecrackers these days, and the Qiantang River control project is huge, with the river embankment on the south and north being more than 200 miles long. Starting from Minghe Salt Field in the south, to Fengfeng Town to Xiaoshan-Hangzhou, this is all secondary. The south and the disaster has not been greatly affected. The key is the north, and it is necessary to control it from Qingxia Salt Field (in the southwest of Nanhui, but Nanhui and Chuansha are all in the sea at this time), and to Jinshan-Ninghai (a few dozen miles south of Pudong Airport, more than ten miles south of Haiyan, and later all become Qiantang River Bay)-Yanmen Mountain-Zheshan (later on Xiaoshan on the south bank, but at this time on Yanban on the north bank).

Involved in the four prefectures, nearly ten direct counties were reached, and the imperial court did not give much money. Zhang Xia was helpless and knew that the Qian family's stone cage method was very good, but he did not dare to adopt the Shitang method on the entire line and continued to use Chaitang-Caotang and Tutang.[]

If this is very risky, you must carefully examine the embankment. Where to use stone ponds and where to save costs, use grass ponds and earth ponds must be repeatedly investigated and considered.

The convenience provided by the imperial court was an army. The Northern Song Dynasty set up a unit of two thousand people in the army, called the Hanjiang Army, which was specially used to control Qiantang River and seawalls.

The army has two benefits: professional troops with high technical level and can do it. The second is that the court pays expenses, does not impose much taxes on the people, and only imposes a small amount of force on the people, so that the people will not be under pressure from the people.

But there are many places that still make him worry, such as the direction of Hangzhou City.

Hangzhou City is not far from Qiantang River. - The river embankment here has been washed away, so he doesn't believe in any celestial phenomena. If the weather is bad, even if the stone pond is built, it may not work. It will still collapse. - The river embankment here will be unimaginable.

If you die, don’t be sad. Who says you don’t have a backstage?

But at this time, Juzhou was preparing to welcome the new magistrate.

This is to build a dike, not a dike.

As long as you have enough strength, you can circle Taihu Lake. But how dangerous is the sea tide?

Zhang Xia's idea was very extreme. He really circled Taihu Lake. Without this large reservoir, he had to spread his wings.

But Zhang Xia was secretly squeezing Zheng Lang.

Taipingzhou is a miracle that has to admit the facts.

But Taipingzhou is a small prefecture in the south of the Yangtze River, with a population of only three counties. If it weren't for the fact that there were only more than 30,000 households, less than 30,000 households, and not many families with backgrounds. When Zheng Lang went there, the people had no hope except curiosity. This is Hangzhou! - It happened to be reversed.

Zhang Xia was very familiar with this and was originally from Xiaoshan.

After all, what Zheng Lang did in Taipingzhou can be called a miracle.

This is not too difficult or too easy to do with his ability. And the public opinion is like this. As a minister, the most rational way is to take the initiative to avoid it. You are not a magistrate, but you will also be a prime minister in the future. It is not good to have a high reputation. The people's desire is so strong that you should avoid it. The couple will quarrel and say a few words, and it is between officials and the people. Just like when you go to Taipingzhou... Why do you punish several households to establish authority? If you choose so many prefectures in the world, why do you have to come to Hangzhou? You can go to Suzhou, Xiuzhou-Mingzhou-Yuezhou-Yangzhou-Huzhou-Jiangning. These prefectures are very good. Hangzhou is prosperous, but it has reached the extreme. For example, commercial tax, Hangzhou-average is 120,000 guan, Jiangning is 57,000 guan, and Qizhou is 27,000 guan, and like the remote Fengzhou, less than 2,000 guan.

He has never heard of the virgin land Zheng Lang mentioned, but he knows that the more the vacuum it is, the more mediocre officials will worry, but the more capable officials will achieve political achievements.

Hangzhou has reached such an extreme. For example, the wine tax, the four capitals only have one million guan, about 500,000 yuan each of the four routes in Beijing, more than 800,000 yuan each, two routes in Hebei, only tens of thousands of yuan, and only tens of thousands of yuan in Lizhou and Zizhou, but not in Kuizhou. However, Liangzhe Road reached one million guan, and forty percent concentrated in Hangzhou.

Yanliangzhe Road - more than one million stones, Hangzhou also needs to divide 100% of the 100% of the income of the Maritime Commission, the income of the two taxes, and the income of the two taxes are targeted at farmers. There are very few Hangzhou, which are far from Yuezhou, and even worse than Huzhou. However, there are also personal income taxes that are the top in the southeast, Chenggu Tax, as well as various supervisors and mineral deposit income, which constitute the main income of Hangzhou. However, most of these incomes are not easy to move in Hangzhou.

What to do in this situation?

If you have the ability to decorate a few flowers, you can’t show your style even if you put them in Hangzhou where all the flowers are blooming.

I couldn't figure it out, so I looked through the drawings in my hand.

The most feared thing about Qiantang River is from June to September, with many storms and heavy tides, and the most prone season for accidents. However, the project has not been repaired, so it has to work hard to repair some critical areas first to prepare for the coming flood season.

Suddenly the gatekeeper came in and reported: "Alang, there were two young men outside the gate asking for a meeting, saying that they were students of Zheng Lang, who was about to serve as the new magistrate."

As he said that, he handed over two greetings.

Zhang Xia was a little puzzled. As far as he knew, Zheng Lang had not set off, so why did he let the two students come first?

Looking at the two beautiful small words on the prayer post, I smiled bitterly - and said: "Let them come in..."

Not only did Zhang Xia, the two students, have to pay attention to them, but he did not dare to underestimate the subsequent series of officials. Hangzhou City was in a bustling future.

——After a while, Wang Anshi and Yan Rong were brought in.

He is very cautious about these two sons Zhang Xia.

Several students participated in the book written by Zheng Lang, and they could see the importance of it. The one who spoke the most seemed to be Wang Anshi, followed by Sima Guang. The two sons have been famous for a long time. I don’t know if their personality has become calm, but among the six students of Zheng Lang, only these two sons have the greatest prospects.

Yan Rong was not just a so-called man. The news he received from the capital was that Deputy Prime Minister Chen Zhizhong had a young girl. For some reason, he got married to the Yan family in the capital.

This made Zhang Xia very ashamed.

The son-in-law is becoming more and more difficult to catch in the future. Before the scientific examination, he has to catch him.

But the inside story is even more complicated than he thought. Chen Zhizhong's daughter was born by a concubine and had a lower status. However, after Chen Zhizhong was promoted to deputy prime minister, the waters rose and the ship was higher. He was the daughter of the concubine and the young lady of the prime minister's family. After the results were released, he considered it.

——The young men who like him may not be able to like him, his illegitimate daughter, or he may not be able to like him. After seeing the new doctrine of the mean, he focused his eyes on Zheng Lang and some students. Fan Zhongyan’s two sons dared not think about it, and his two sons were young, and they could not consider it. Wang Anshi’s family was in the south. So he stared at the Yan family and sent someone to tactfully talk to the Yan family. What is the ability of the Yan family to say that they disagree?

The worst thing is that Yan Rong is much more of a young wife, who he doesn't know yet. It just so happened that Zheng Lang released him and Wang Anshi and sent a letter to the Yan family.

The two walked in, bowed respectfully, and sang a fat noo: "I have met Zhang Zhuanyun Commander."

From now on, this person will be half of Zheng Lang's boss, and his governing yamen is also in Hangzhou City.

You need to know the severity of the middle.

"You sit down, come and make tea for the two men."

The servant brought two cups of tea.

Zhang Xia asked:...What's the matter with you here?"

"Zhang Zhuanyun, we came here to look around on the order of Doctor Zheng."

It made Zhang Xia feel very depressed.

But the hero is not young, although he is young, he is indeed qualified to watch it. For example, how big is Zheng Lang's place in Taipingzhou?

"Then why come to my house?"

"This is a letter from Doctor Zheng to you." Wang Anshi said.

"Oh, bring it," Zhang Xia said.

Wang Anshi handed out a letter from his arms.

It is Zheng Lang's more scientific method of pond management, fish scale pond.

Qian's bamboo cage method is relatively advanced, but there are also bad things. Now there is no iron wire, and when binding bamboo cages, you can only tie them with hemp rope or even straw ropes. Then put the stones in it and lay the wood and lay them in it to prevent solidification.

However, the sea tide hits the river embankment every moment and throws away the storm. When the moon is full, the Qiantang River will be replaced with a werewolf, fierce and fierce attack, spreading its wings and hitting the dam embankment again and again.

If the treatment is not treated for a long time, or the treatment is slackened, the mud and soil filled in the cracks of the stone will be shaken and washed away, and the stone will continue to shake, causing the ropes tied to the bamboo cage to loosen and rot, or even be grounded off by the stones. The bamboo cage collapses, the river embankment collapses, and the dam breaks.

It’s not OK to have iron wire, but there is also a rust process.

Later, the wooden board method appeared, but the cost was expensive and unreasonable, so a more scientific pond embankment method, fish scale pond.

This wonderful idea comes from the plank road.

In ancient times, the road leading to the outside world was inconvenient. Individuals could cross mountains and ridges with empty bodies, but with baggage and vehicles, how could they cross the mountains? Then they came up with a method to cut holes from the cliffs, stuff wood into the holes, and lay wooden boards on it. Especially the plank roads leading from Sichuan to northern Shaanxi were mostly in this form. There were also some dangerous rivers that were not easy to pull fibers. This method was used to lay a plank road, and then tap the eye on the plank roads, and tie a stone ring on it for the boatmen to leverage the force when scratching. For example, when Sanmenxia passed by, the Sanmen canal transport was far inferior to the Tang Dynasty in the Song Dynasty. There were still people using the Tang Dynasty plank roads to pull the ships through Sanmen and reach Guanzhong. The northwest battle was about to start, and this road canal transport would be more important.

Later generations combined the bamboo cage method with plank road methods, and no longer used bamboo cages, and directly placed stones in the tide. However, the stones on the outer side were equipped with stone rings, and the stone rings were connected with ropes. Because it was not a bamboo cage, the stone rings were all outside the embankment, which made it easier to replace the ropes. But in this way, the stone walls on the outer side formed a whole. Even the stones inside could be connected in this way to form a whole dam. Then fill it with mud and ash, and lay down wooden rafts.

From a distance, the river embankment looks like a piece of fish scale, so it is also called a fish scale pond.

The cost is slightly higher, but not much higher than the bamboo cage method.

But what about the fruit?

In the eyes of everyone like Zhang Xia, he immediately felt something was wrong. He asked in surprise: "Why didn't you notify someone earlier?"

Wang Anshi asked back strangely: "This must be thought about slowly. Doctor Zheng said that the ability of water conservancy is that you can be ranked among the top three in my court. You didn't even think about it. How could Doctor Zheng think about it next time?"

This is not the case.

In fact, Zhang Xia's dike control effect this time was significant. Without this fish scale pond, the Qiantang River would be peaceful in the next few decades. If you gave this method in advance, it would be equivalent to robbing the credit from Zhang Xia. You should only give it to him when you practice it until it was almost done.

It's not to give, it's also a display of ability.

Otherwise, Zhang Xiaruo would not like him, and in a city, it would be difficult to do what he did. And what he did might be something that the Chinese people had never done since ancient times.

Wang Anshi didn't know the real situation inside, so he immediately refuted it.

Zhang Xia was speechless.

Yes, it is just a Qian family bamboo cage method to build a dike, which seems very simple, but why did no one think of it before?

This method is also very simple. Just like building a dike, it is a simple method. However, after thousands of years, who remembers it?

Wang Anshi said again: "Doctor Zheng still has a concern."

"What Gu Zhi..."

"The best way is here." As he said that, he took out a letter, which was actually a drawing and some explanation. The best fish scale pond was to allow stones to crisscross and chisel the grooves between the stones. This was similar to the principle of stringing stones with ropes, which could cause changes later. It was not a rope but a cast iron to force it, and water it with putty and glutinous rice slurry at the joints. Next, it was a kind of dam, and nailed it to the bottom of the stone pond with plum blossom piles and horse-tooth piles.

Only a new change is generated in the middle.

But this is the real fish scale pond, but the cost is also the real cost.

So it is ranked alongside the Great Wall-Grand Canal as one of the three major civil engineering projects in China.

The key is cost considerations, and the Qiantang River is not the later trumpets. The trumpets are the most harmful. The salt officials and the sea salt people have been tossed by this trumpet for hundreds of years.

Now it’s a triangle without any obstacles to the tide—the font is coming—I’m here next time I arrive in Hangzhou.

But when we arrived in Hangzhou, the power of the trend gradually decreased. Hangzhou was the most miserable, followed by salt officials and sea salt. It was harmful, but it was far less harmful than later generations. Is it worth using this most expensive fish scale pond method? Zheng Lang made some improvements and used ropes instead of cast iron.

Zhang Xia was a little worried with two drawings in his hand, and if there was something, they all reached this level. Seeing that the Zheng family also agreed with the previous method, the funding was a serious constraint.

It is best to think that the best way to do it forever or to go back.

"We disturbed Zhang Zhuanyun Commander..." Wang Anshi and Yan Rong bowed and said goodbye.

How to choose is Zhang Xia's business, Zheng Lang will never interfere, and the two young masters are even more difficult to interfere.
