"It's bitter, it's really bitter!"

Zhou Jinyi dragged his tired steps and walked back to the workshop where he settled step by step - a simple house made of wooden planks.

It's hot to death in the summer, and shivering in the winter.

The thickness of the planks of this simple house will not exceed one finger, and it is used for an egg in the ice and snow.

Not to mention in the summer, every winter, if you don't build a circle of adobe walls on the four sides early, it is the rhythm of freezing to death.

That is, on the embankment construction site, there is not much else, just a lot of water and mud.

The thin simple houses are now surrounded by a thick layer of adobe houses, which are stuffed with canvas and straw to keep the planks dry. The roof of the house was also covered with a thick canvas, and thick straw mats were spread on it, so that the workshop on the embankment did not freeze to death in the winter.

This is the Bianhe construction site located in the territory of Chenliu, Kaifeng Prefecture, Central Plains Province.

Those who know the city of Tokyo in the old Zhao and Song dynasties know the importance of the Bianhe River, which has four canals in Tokyo, and the Bianhe River is the most. The country's richest southeast six road (Huainan Road, Jiangnan East and West Road, Jinghu South and North Road, Liangzhejiang Road) of the grain department store, are transported to Beijing by the canal, the so-called "Cao leads the rivers and lakes, the South China Sea, half of the world's wealth, and the mountains and rivers of the department store, all from this road."

After the fall of the Zhao and Song dynasties, Lu Qian never thought of setting the capital of the country in Kaifeng, the biggest reason was not that there was no danger to defend there, but because of the transfer of food and materials in this place, just like what Zhao Da said when he faced Zhao Er, 'There is no danger in Germany': In less than a hundred years, the people of the world will be exhausted!

But having said that, Lu Qian would not watch the Bianhe River being silted up by yellow sand in vain.

Although Kaifeng is no longer the capital of the country, the four canals of Caoyun are still the lifeblood of transportation connecting the Central Plains and all directions. In today's day and age, water transport is much less time-consuming than land transport.

The Bianhe River is based on the Yellow River, so like the Yellow River, it has the characteristics of uneven water flow and high sediment content. In the past, in order to keep the Bianhe River unblocked, the Zhao and Song dynasties had to invest a lot of manpower and material resources every year. First of all, it divides the water of the Yellow River, Biankou, because of the turbidity of the water flow, the sediment content increases, and it is difficult to navigate without frequent dredging. During the Dazhong Xiangfu period, the Zhao and Song dynasties had a rule - every three or five years, but the riverbed was still silted up every year. By the time of Zhenzong, it had begun to become a state of hanging rivers on the ground, and by the time of the Renzong Dynasty, it had been stipulated that it should be passed every year. Biankou closes in winter and opens in spring, and the Bianhe River flows for more than 200 days every year. Even so, in the Xining period, in the area of Yongqiu and Xiangyi in the east of Kaifeng, the bottom of the Bianhe River is more than one zhang and two feet above the flat land outside the embankment, and the dwellings are overlooked from the bottom of the embankment, such as in the deep valley.

Lu Qian has no good idea to solve this problem, and it seems that the only thing he can do is to maintain water and soil in the upper reaches of the Yellow River and prohibit indiscriminate logging. But these are not things that can be seen in a short period of time.

What to do? Have you abolished the Bianhe River in vain? Lu Qian was reluctant. Therefore, every year, the manpower was organized, and even the Ministry of Industry was once asked to restore the setting of Zhao Song's shallow army there.

In ancient times, there was also dredging and dredging of rivers, and it was very ordinary. There are many kinds of tools.

For example, with a few catties of iron for the claw shape, with a rope tied to the tail of the boat and sink to the water, the work is urgent, the stream goes down one after another, and the water is several feet deep. Or take a huge log eight feet long, and the teeth are two feet long, and they are listed under the wood, like a rake, and they are pressed with stones, and they are tied with big ropes on both sides, and the big boats are tied at both ends, and they are eighty paces apart, and each of them is twisted with a pulley, and they come and go to scratch the mud and sand, and they have moved the boat to dredge......

But in Lu Qian's eyes, there are some symptoms but not cures, because such a swinging sediment will eventually sink again in a certain section of the river downstream. At that time, the Ministry of Industry received a task - to think of a way to get the sediment out.

This is very different from the previous method, but it still responds to that sentence, and the method is all thought up by people.

A waterwheel and a rollover solve this problem, although the efficiency is somewhat low.

The large waterwheel is made of pig iron and hardwood, and has a sturdy texture. It is placed in the center of the boat, and the hull is also hollow, leaving enough space for the water wheel. Then it is driven by animal power, the waterwheel rotates, the iron scraper at the bottom is used to scrape the sediment, and the water bucket is used to hold the sediment. The sediment and river water were all deposited in the sedimentation tank, and the sediment was left behind, and the river water was led overboard by a small overturned truck.

The reason why this method is not efficient is because this kind of sand dredging boat also needs to determine the height of the waterwheel according to the depth of the river, and the water depth of the river is too deep, this kind of sand dredging boat is useless. The waterwheel is not reachable, so it can only be overturned with a smaller efficiency, but the depth is also limited.

This is also the limitation of the times.

The construction site where Zhou Jinyi is located is not in Biankou, but in Chenliu.

In the winter, there are no boats, but the sand dredging boats and supporting masons are even busier. In this section of the river, four sand dredging boats move back and forth on the water with a total length of five miles around the clock.

It is difficult to pick up the thick ice on the water.

At the same time, piles of sediment were also sent to the shore by sand dredging boats, and then there were small laborers like Zhou Jinyi who worked as coolies.

The sediment at the bottom of the river will not be abandoned in vain, and it is mainly used to pave roads in the riverside area of Central Plains Province. No matter how far away it is, it is not cost-effective to transport sand.

But these are not Zhou Jinyi's considerations, his only idea is to make money, and then save money. Let the total assets and savings of the family all meet the standard, and the provincial immigration bureau will be recorded by those who do not do personnel.

Therefore, he did not dare to eat, and he did not dare to drink. It seems that the only thing left to be the biggest interest in every day is to look at the passbook.

Thinking that today is his birthday, but his home is hundreds of miles away in Hedong. That place is the place with the strictest immigration bureau system among the more than a dozen provinces in the Central Plains. Ordinary people don't know what makes the immigration bureau in their province so hateful. However, many figures in Lu Qi's officialdom knew that this matter was due to Emperor Lu's instructions.

A Hedong [Jiatongfu], with a population of more than 8 million, is naturally much less than that of Jinxi in later generations, but in today's era, this population density is not bad at all.

In this way, in the years since the establishment of Lu Qi, more than two million people from Hedong have been successively relocated to the Hetao region, or the land of Western Xia. Including the area north of the Yellow River, hundreds of thousands of people have also migrated one after another.

Controlling the number of people in Hedong within five million, this plan is the same as the Guanzhong people's reduction plan, although the fundamental starting point is to make it more convenient for 'immigrants', it cannot be denied that there is Lu Qian's subjective emotional factor in it.

When the population is small, the land can be 'restored'. Dye the Loess Plateau green, Lu Qian's wish is very simple, very 'foolish'.

But the consequence is that many people in Hedong, like Zhou Jinyi, are keeping their eyes firmly on their total assets and savings, lest they accidentally end up "on the list".

And the 'poverty standard' of Hedong Province is second to none in the whole of Middle-earth, no, it is outstanding and stands out from the crowd.

It is almost like using administrative methods to force people from all walks of life in Hedong to rack their brains to make money. This is because the 'poverty line' in Hedong can increase with time.

For people like Zhou Jinyi, who are always hovering on the passing line, all they can do is not to miss any opportunity to make money, and at the same time, to carry forward the tradition of Hedong Laojiao.

Obviously it was his birthday, but Zhou Jinyi was still reluctant to eat and drink. I went around the canteens of all the sizes on the construction site, painted cakes to satisfy my hunger, and went back to the workshop with a piece of oil cake in my hand. On the road, he kept sighing: "Bitter, bitter, bitter......"

Thinking that his family had a bank deposit of as much as 300 yuan, and his family was full of grain and rice, 30 years ago, the landlords in the village were not necessarily as wealthy as his family, but how could they not even dare to 'eat and drink'?

Alas, sighing, Zhou Jinyi pushed open the door.
