In the north of the palace, the Chongguang Hall of Hualin Garden, the officials of the starting department used the architectural model to explain the construction of Huaiyin to the emperor, the queen mother and the prime ministers.

The journey refers specifically to the place where the emperor visited. Huaiyin was built outside Huaiyin City. Because it actually assumed the responsibility of other capitals, the construction scale was quite large.

Li Li was also present, after all, he was one of the "designs" and supervisors who were in the city.

Overall, Huaiyin Xing is rectangular, and the city implements the Lifang system.

The city is divided into nine rectangular areas of the same size according to the nine-cup grid. The uppermost (northmost) row of three "grids", and the middle "grid" is the palace area, including the palace and the official office.

There are two squares on the left and right, which are residential areas for officials, royal families and various noble people.

Except for the palace city, there are nine fangs in the other eight "big grids", all of which have fang walls, and four gates (big squares) or two gates (small squares).

There are roads separated between the various yards, so overall, walking is like a chessboard.

Based on the construction experience of Hanshan Two City, Li Li organized personnel to design a complete drainage (fouling) pipeline network for the industry.

This drainage (fouling) pipeline network is constructed simultaneously when the city is built, ensuring that a large number of people move in and out of the city can be discharged in time for daily sewage and excrement from each house (rather than only Guiren’s residential areas).

It will not cause rainwater to flow backwards due to flooding during the rainy season, causing sewage from all the towns and even the streets in the city to flow.

In addition, based on the "municipal construction" experience of Hanshan City, Li Li made all the pavements in the streets in the city "hardened", that is, laying a large number of bluestone pavements and cement pavements.

Because of a complete drainage network, it can ensure that there is no too much soil, dirt and water accumulation on the road surface.

Therefore, the roads in the city will not be filled with dust on sunny days and muddy on rainy days.

For nobles who have cars to travel, it doesn’t matter whether the road is hard or not, but for ordinary people and small officials, you don’t have to walk on muddy streets with sewage flowing in rainy days, which is a kind of convenience.

In addition, Li Li was not a professional, so he did not participate in the details of the city's buildings, such as the layout of the palace and the style of each palace.

Emperor Xiao Xun looked at the city model and looked forward to it, looking forward to a new life in Huaiyin after its completion.

But after all, he was young, and neither experience nor knowledge was enough to ask many in-depth questions, nor to understand various engineering terms and the exquisiteness of palace design.

Therefore, the explanations of the officials of the starting department were actually for the Empress Dowager and the Prime Minister.

Seeing that his son was distracted as he listened, the empress dowager knew that his son was not energetic, he ended the explanation at the right time and then began the next "stage".

New money issuance.

This year is the first year of Tai'an. Because of the discovery and mining of the Le'an copper mine in Raozhou, copper production will inevitably increase greatly, so the court decided to cast a new type of copper coins, named "Tai'an Wuzhu".

Some officials presented sample coins for the emperor, queen mother and prime minister to check.

Tai'an Wuzhu, the shape is the same as that of Wuzhu coins. It is round on the outside and square on the inside. The round has an outer contour, and the square hole has an inner contour.

The front is the four characters "Tai'an Wuzhu". The two characters Tai and An are structured up and down, and the two characters Wu and Zhu are arranged left and right.

There is no word on the back, but two crossed wheat ears (yang text pattern), one on the left and the other on the right, sandwiched the square hole in the center.

These two wheat ears are actually one wheat and two ears, which is "Jiahe", which has the meaning of peace in the world.

Overall, Tai'an Wuzhu is still in the normal Wuzhu coin form, without effective anti-counterfeiting measures. Once issued, someone will soon mint counterfeit coins or store a large number of good coins.

After a while, the Tai'an Wuzhu circulated on the market was either shoddy counterfeit coins or incomplete, with edge cuts and holes.

Is that true?

It doesn’t matter. Anyway, the more Tai'an Wuzhu is invested in circulation, the more the imperial court will earn. As for what "state" the Tai'an Wuzhu will become after circulation, I can’t help it, so I don’t have to worry about it.

Because Tai'an Wuzhu is not made in batches with coin models, but is made in batches with machines, and is a "mechanical currency".

And it is not all copper, but metals such as lead are added appropriately. Therefore, the cost of making coins in Tai'an Wuzhu is lower than its face value. The more you do, the more you earn.

It is the first time that making coins can make money (except for over-issuing large amounts of coins).

Xiao Xun didn't understand what this meant, so Daqian, the king of Jiangxia, explained to his nephew.

Throughout the dynasties, the cost of minting coins (the overall cost, not just the cost of minting) must be higher than the face value of the minted coins.

For example, if the government wants to make one thousand five-zhu coins (one thousand documents), it will cost 1,100 documents.

Therefore, for the court, minting coins is a loss, but it has to be done because the people need coins.

Also, because overall, there is a problem because there is a shortage of copper in the world and the price of copper is relatively high:

After the good copper coins are melted, even if they are deducted and consumed, they will be sold as copper materials. The price is still higher than the face value of the copper coins.

Therefore, good quality copper coins have become a powerful tool for making money: they can make money by melting the good copper coins and selling them as copper materials.

In addition, the people need a large amount of copper ware, so a large amount of good money was melted and cast copper ware.

Or try to use copper coins, cut edges (cut the outer contour to get copper, causing the round coins to become polygons), and drill holes (cut square holes to get copper, causing the square holes of copper coins to become larger) and use copper.

There are also a large number of wealthy families who store good money on a large scale, so good copper coins disappear, which is not enough.

In order to maintain the normal demand for coins by the people, the imperial court could only continue to mint a large amount of coins and then continue to lose money.

When the country is strong, it is still affordable. Once the finances are tight, the currency system will inevitably be corrupt.

Xiao Xun seemed to understand but not understand, and Daqian Xiao continued to explain.

The Tai'an Wuzhu produced by the new technology does not require any anti-counterfeiting measures, and it cannot be prevented.

Anyway, the production cost (total cost) is lower than its face value, so as long as it is circulated, the government can make money.

Coupled with the years of external sales of Le'an's "water copper", the copper price has slowly dropped. If illegal businessmen want to melt Tai'an Wuzhu into copper, they will be sold as copper materials, and deduct various costs, they will most likely make little profit or even lose money.

If Le'an copper mine is mined on a large scale in the future, the government will sell a large amount of copper materials to the public, which will give the public a reliable source of copper materials and appropriately alleviate the copper shortage, and the copper price will inevitably fall in one step.

Therefore, the profits of melting money to resell copper will be further reduced.

If fewer people want to play Tai'an Wuzhu, the chances of Tai'an Wuzhu circulating on the market will decrease, and the money shortage among the people will be alleviated.

This is very beneficial to the court's rectification of the currency system.

Xiao Xun still couldn't understand what his uncle introduced about Xin Qian.

The Queen Mother wanted to mention something, but she was anxious and didn't know how to tell her son the complicated truth in simple words.

Li Li explained appropriately, saying that new money has two benefits.

First, it was the first time since ancient times that it was possible to make a profit by coin trading, which was amazing. Several late emperors did not do it back then.

Second, new money will be used by many people, and users will not deliberately destroy such a good copper coins, because this is Tai'an Wuzhu, which is better than ordinary Wuzhu coins.

After saying this, Xiao Xun immediately understood:

I did something that my great-grandfather, grandfather, and father did not do!

My new money is very good, better than other Wuzhu coins!

Children always hope that their achievements can be recognized by their parents and elders, and always hope that their performance will be better than their peers.

Now, the general told him directly what was good about Tai'an Wuzhu.

Xiao Xun's excitement was beyond words. When Xiao Daqian saw it, he felt helpless: I was so dry that I was not as good as Mr. Pengcheng for two or three sentences?

The introduction of Tai'an Wuzhu ended, but the introduction of the new money continues.

Next, a copper coin named "Tai'an Tongbao" appeared.

This kind of copper coin has a special shape because the hole in the middle is a round hole.

The weight of a coin is fifteen zhu, which is the weight of three five zhu coins, and its currency value should be three.

However, the nominal face value is Yimo, that is, one hundred people.

So this is a big money of "one (text) to be thirty-three (text)" or "one (piece) to be 100 (piece)".

Generally speaking, when the court began to issue "10 coins", "100 coins" and "100 coins", its purpose must be to plunder the people's wealth on a large scale.

This kind of money will inevitably have a bad reputation and will soon "depreciate" and withdraw from circulation.

Whoever issues such money is committing evil.

So, how should we explain to the Shao Emperor the "diligence" of the imperial court in issuing such a face value of Yimo (100 documents) copper coins?

Everyone's eyes gathered on Li Li.

This is your idea, please explain it to your son-in-law!
