Daming: I asked you to hang yourself, but I didn’t ask you to rebuild the Ming Dynasty

As for the connection between the old and new sections - later generations usually used pre-buried stones to connect.

Reserved lacing interface is also a solution.

To put it bluntly, half of the stone and steel bars are inside the wall built first.

The other half will be embedded in the new wall when it is built.

Let’s explain it more simply——

“It’s like two steel pipes, how can they be connected without welding?

Naturally, a steel pipe or wooden stick is stuffed inside! "

This is called "biting the stubble".

However, the city wall must resist shelling, and the effect of pre-embedded stones is better!

Later highways, bridge bases, and dams were usually constructed using a combination of steel bars and stones.

Preventive measures for shrinkage stress, methods for connecting old and new walls...

To put it bluntly, it’s worthless!

The shrinkage stress of rammed earth city walls is even greater!

The ancients could solve it perfectly!

——Not to mention the shrinkage stress of cement buildings...

In Zhu Youjian's plan, these small officials were the contractors of each construction team.

That is, those who gain immediate benefits.

In other words - Zhu Youjian's state-led new capital group - vested interests at the grassroots level.

It's just that they are unified under the imperial power and put on the cloak of officials!

In other words, the new Ming Dynasty created by Zhu Youjian can be called another name - capitalism dominated by imperial power.

A name is just a name.

Those who carve a boat and seek a sword have long been nailed to the pillar of shame in history.

The essence is the truth.

In other words, Zhu Youjian's series of methods completely built New Daming into an integrated new capital group.

Officials are just the leadership within a joint-stock company.

Near Hanjiang Commercial House is Lime Mountain.

This is a big mountain outside Nanjing.

It is called Shogun Mountain in history books.

This is the raw material production area for cement.

As for iron-making slag, there is a lot of it around Nanjing!

Anqing was the center of Suzhou Steel Industry in the Ming Dynasty, with mountains of slag piled up.

As for another raw material, clay, it can be found everywhere.

As for coal, is it missing from a place that can burn steel?

Limestone and clay are ground into flour, and the clinker is calcined at 1450 degrees, and then ground together with the slag left after ironmaking.

As for the proportion, the proportion of cement raw materials should be determined according to the actual situation and is not a cookie-cutter formula.

大概为石灰石67-75%，粘土10-15%，铁矿0.5-1.5%，还有煤8.5-11%。

Grind first, then burn, then grind again, and what comes out is cement!

The firing of cement is just a layer of window paper. If it is pierced, what is the difficulty?

Officials who have built countless cement plants have already built blast furnaces for firing cement everywhere.

Using local materials is inexhaustible!

There is no need to worry about cement production.

With a steam engine, are you still worried about not having the power to grind?

Besides, Nanjing is close to the Yangtze River, and its hydraulic workshops have been mature since the Western Han Dynasty.

Those who are leading the work are all vested interests of Zhu Youjian's new Ming Dynasty.

The civilian husbands below are actually local people in Nanjing.

How many people are there in Nanjing?

According to Ming history records, during the Hongwu period in the early Ming Dynasty, the capital city (i.e., within the third city wall wrapped entirely in bricks and stones) had approximately 120 million people.

At that time, within the outer perimeter (the fourth layer of the city wall, 120 miles long), there were still large areas of farmland, which was very empty.

However, by the end of the Ming Dynasty, not only had the outer perimeter been filled up, but even outside the outer perimeter, there were towns all over the place.

For example: Gu Mengyou "lived as a commoner for the rest of his life, and saw Shenzong in full power. There were millions of families in the city"...

In the last years of Chongzhen, He Dongru: "Millions of living beings were left in the capital"...

"Matteo Ricci's Notes on China": "Matteo Ricci landed in a suburb outside the triple wall of Nanjing. This place is very large and densely populated, and can be called a big city..."

Look - a suburb, Matteo Ricci, who came all the way from the West, thought it was a big city!

There is even a saying in Nanjing during the Ming Dynasty——

Two men rode in opposite directions along the city wall and met again a day later.

According to records left by people in the Ming Dynasty, the population of Nanjing was at least 300 million.

It is even possible that the number exceeded 500 million!

In fact, as long as the population of a single city in the Ming Dynasty is verified, the rumor that the Ming Dynasty only had 6000 to [-] million people will be self-defeating!

——Well, one tenth of them live in Nanjing...

Very impressed!

Even in modern times, as infrastructure enthusiasts, can we have a city that can accommodate [-] million people?

As for Beijing, according to research, it has more than 200 million people!

Guangzhou, Yangzhou, Suzhou, Nanyang, Wuchang Three Towns, Chang'an, Kaifeng, Chengdu, Hangzhou, Jinan, Nanchang...

At that time, this was a big city with a population of more than one million, or even 200 million!

You know, at that time, a Linqing who was not ranked was massacred by 90 people!

At this urbanization rate, even if a bad guy comes, he still has to kneel down and call daddy!

Then there are more than 1000 counties!

Even if there are only 3000 people in a county, it is so close to [-] million!

Even by the end of the Ming Dynasty, there were still 140 prefectures, 193 prefectures, 493 wards, and 359 schools!

Oh open!

There aren’t enough people!

how?

In the Ming Dynasty, all people lived in the city and drove to the countryside to farm?

Oh!

That's right. Didn't people say that if you don't have money, just rent out the house in the countryside...

In the Ming Dynasty, people drove their cars to the countryside to farm—not surprising!

To show off your IQ, you just need to close your eyes and talk blindly!

As for whether I will laugh...

As long as you don't laugh on the spot - you won't have to grin for three days behind the scenes!

There’s so much money coming in again!

Pooh!

A bunch of rubbish who create rumors just for the sake of kneeling and licking!

……

Speaking of Nanjing City, I suddenly remembered a historical record——

"The streets of Jinling are extremely wide and can accommodate nine tracks."

What do you mean?

The streets of Nanjing City are large enough to accommodate nine carriages traveling in parallel!

The Zhonghua Gate in Nanjing (not the largest city gate in the Ming Dynasty) is 21.45 meters high.

The tallest city gate in Beijing during the Ming Dynasty was Beijing Zhengyang Gate (Yongding Gate), 43.65 meters high.

Just looking at these two city gate towers, the prosperity of the Ming Dynasty can be seen.

In the burned-out corner of history, the glory of the Ming Dynasty can still be vaguely seen.

It’s just a shame that to this day, when people mention the Ming Dynasty, people’s stereotype is that the Ming Dynasty was a dark age...

I have to say, this is sad.

What a shame!

A shame for billions of people!

……

At this time, the city of Nanjing had not suffered any harm from the Qing court.

Not to mention 20% of the area was designated as a city where Han people were not allowed to enter!

Although Nanjing is the capital of Jiangnan where the wealthy and gentry class rush to flock, there are even more ordinary people gathering here!

Nanjing has a population of millions, and even if only half of them are ordinary people, it is already very scary.

Youdao means that there is strength in numbers.

Spurred by Fang Zhenghua's generous spending of money and the payment of money according to the amount, these Nanjing civilians wished that their whole families, old and young, could join the battle.

A digger digs a basket of soil, which is money!

Brick movers, if you move a brick, it’s money!

For those who dissect wood, every piece of wood shoveled out is money!
