The second situation is that excessive silver and copper coins are invested in a region, resulting in local inflation."

"For example, in the western Liaoning area at the end of the Ming Dynasty, the land was barren, the climate was cold, and the grain output was very low."

"In order to resist the invasion of the Later Jin Dynasty, a large number of troops were stationed in western Liaoning. The large amount of military pay allocated to the garrison led to a significant increase in the circulation of silver in western Liaoning, and eventually caused the soaring prices in western Liaoning."

Yang Gan couldn't help but talk, and the expression on his face seemed to be saying, Come on, come on, come and praise me.

Zhang Yumeng couldn't see Yang Gan's tail up to the sky, and smiled, "Then you know inflation very well, let's talk about its meaning."

Yang Gan's mouth twitched hard, almost biting his tongue. After thinking for a long time, he finally said helplessly.

"Come on, I can't pretend to be this wave. I only know that inflation is still the kind that can only be understood but not expressed in words."

Zhang Yumeng said proudly, "Inflation generally refers to the credit currency system, the amount of currency in circulation exceeds the actual economic demand and the continuous rise in price levels caused by currency depreciation and the continuous increase in price levels."

"In words that can be understood, money is worthless, because in modernization, paper money is actually not valuable, but the state has given it value with its own credit." ъìＱυＧΕt�.℃ǒΜ

"But ancient coins are different, they are valuable in themselves, so I thought about it. The easiest way is to make as many coins as you have now."

"By the way, don't forget that the lost money, labor costs and all costs are included, so that you don't lose money."

"What does that mean?"

Zhang Yumeng said, "Simply put, all the miscellaneous expenses such as your principal, labor costs, loss costs, etc. are added together, and it is enough to correspond to the current money, otherwise you will lose to death."

Yang Gan suddenly realized that this should be a waste of money. He looked at Zhang Yumeng blankly, "Don't tell me, you are still studying finance?"

"Uh? People may not have knowledge, but they cannot have common sense. I have always had financial management, so I still have to understand this."

Zhang Yumeng's expression that she had used to was so common that Yang Gan was very crazy.

At this time, the room became quiet.

Almost everyone looked at Zhang Yumeng with shock.

"Xiao Niang Zhang, you are so awesome."

"Yes, yes, I understand more than Yang Gan."

"Yeye Yeah, Zhang Xiaoniang YYDS."

"It's so disgusting. This wave made her pretend."

Yang Gan looked depressed and said to the girls, "Do you all understand?"

Zhao Wenmo smiled and said, "I didn't understand at all, I just thought it was very powerful."

"Well, I don't know how to be harsh." Yingniang also agreed.

Mu Qing smiled and said, "Although I don't understand it very much, it seems there is good news, right?"

Cao Wushuang said coldly, "Looking at Yang Gan's very obscene expression, you know that he must have taken advantage of it."

Yang Gan laughed and said, "Hahaha, what's cheap? That's a big cheap."

"Hey, hey, I tell you, after a fuss in Dongde County, I was so scared that the tide was so hot that I rushed over. I went there overnight just to give me the right to mint coins so that I could exchange it for the whole family. Safety."

The girls were stunned. They didn't know anything else, but who didn't know the right to mint coins. Whoever had that thing was not a lord with a large number of fiefs or a monarch of a county or a state.

Of course, the coin rights of the seven major counties and states had long been recycled by King Xia Wen. If you don’t seize such an opportunity, you might cause some trouble.

Yang Gan immediately sent a piece of wood, found some tools from Zhang Yumeng's toolbox, and started to snatch the wood.

Not long after, a piece of wooden coins with a slightly thick stake appeared in the eyes of the women.

Yang Gan was very serious and kept measuring it with the ruler. In the eyes of everyone, the wooden coin finally became very thin and small, and he said with satisfaction.

"How about this kind of coin?"

The girls came over to watch the fun.

Zhao Wenmo held the coins and frowned, "This is too small."

Mu Qing nodded and said, "Yes, this feels very similar to Yuankong money, it's just a little smaller."

"It's too thin, I'll break it when I pinch it." Cao Wushuang looked at this speechlessly, and the wooden coins that could be scraped through the cracks of his fingers at any time.

The women expressed their opinions one after another, but Zhang Yumeng supported Yang Gan very much because this style was the round square hole coins that had been passed down for two thousand years in the previous life, and the most classic ancient coins, no doubt about it.

Yang Gan smiled and said, "Actually, have you not noticed it? For example, I bought a knife coin. Many times, I can't buy what I need. A knife coin can buy a hemp rope, a few eggs, and a few kilograms. Corn.”

"But if I only need hemp rope and I don't want anything else, I have to convert it with multiple coins, which is very troublesome."

"If this kind of coin is minted, there will be too many benefits. First, it is said that the sky is round and the place is round, then the coin should be made into a round shape, with a square hole in the middle."

"Second, minting is material-saving and easy to carry. Compared with cloth coins and knife coins, round square hole coins, etc., the size and weight of round square hole coins are small, which means that less copper ore can be used to mint more coins."

"There are clear edges and corners of cloth coins and knife coins, and the round square hole coins are different from this. It is more convenient to carry. Just wrap the copper coins around your waist, which is easy to carry and safe."

"Third: In addition to the convenience of casting and portability, it can also reduce the wear of circulation. Coins act as equivalents in commodity trading. One passes to ten, ten passes to hundreds, and the wear level is very large. For currencies such as knife coins, round square hole money can minimize wear and tear."

As soon as Yang Gan finished speaking, the girls began to talk.

"Yes, yes, every time I go out to buy something, it's easier to wear. Even if the knife coins and cloth coins are placed in the wallet, sometimes it's easy to hook them in and out."

"Yes, although I have a few golds on my body, I don't say that thing is dead, who will give me money to? Except for some large shops, most shops cannot be found."

Mu Qing covered his mouth and chuckled, "So what if you can find it? You can't bring back the money you find it."

Yang Gan pulled Zhang Yumeng over, played with the wooden copper coin in his hand and said, "How about this style?"

Zhang Yumeng quickly took out something from the bottom of the toolbox and measured it carefully.

Yang Gan almost bit his tongue, pointed at the thing, and said incredibly, "Mist, fog grass, vernier caliper? Where did it come from?"

Zhang Yumeng measured the size of the coin and said without caring, "No, of course I did it. Could it be that it was purchased online?"

Yang Gan grabbed his head, and his expression of never seeing the world made all the girls laugh.

They had never seen a vernier caliper, of course they didn't know how powerful it was, but Yang Gan knew it.

Just in line with that sentence, only ignorant people are fearless.

"Diameter 15 mm, thickness 1 mm."

Yang Gan was also a little worried. To be honest, if you play finance well, if you play well, everyone will be good. If you don’t play well, you will be a joke.

In this era when business is not very developed, once fully promoted, if it is not good, it will bring devastating consequences.

It will even directly destroy the monetary system and bring everyone back to the era of bartering.

“Will it be easy to break?”

Zhang Yumeng smiled and said, "No, but if this coin is made, the burrs must be made well. If it is too thin, it will easily cut your hands."

"Then how many denomination coins are you going to make?"

Yang Gan held his chin and thought, "According to the standards, it should be one qian, two qian, five qian, ten qian, and twenty qian."

"Then go further, don't blame me for not reminding you that now our county has a trend of rising business, and many bulk transactions use gold."

"Let's talk about it. After you have finished it, put it on the market first. The market is a good place to test coins. After you slowly improve it, think about something else. Don't take too much steps. If you pull the egg, it will be bad."

After Yang Gan finished speaking, he couldn't help but itchy and grabbed it twice.

Suddenly, Zhang Yumeng smiled unknownly and quipped.

"Rug it?"

"Get out of here, find a way to get this out."

"Okay~~~!"

It took the two of them a long time to finally make the specifications of the coins.

One qian has a diameter of 15 mm, a thickness of 1 mm, and a weight of 5 grams.

Two cents have a diameter of 15 mm, a thickness of 1 mm, and a weight of 7 grams.

Wuqian has a diameter of 18 mm, a thickness of 1.5 mm, and a weight of 10 grams.

Ten thousand cents have a diameter of 20 mm, a thickness of 1.5 mm, and a weight of 15 grams.

Twenty cents are 25 mm in diameter, 2 mm in thickness, and 20 grams in weight.

After discussing for a long time, the two felt that there was no need to stick to the form. Now there is technology, so it is just mold making.

What kind of Tongbao is nothing to do, Yang Gan is a scheming bitch. After all, the right to mint coins was obtained from Haichaohou.

Now that we have a good relationship with Chaoxian, we naturally need to make a good plan.

Don’t think that it’s a son, the king won’t do anything. From ancient times to the present, there have been too many things that the emperor has killed his son.

Yang Gan is not so ungrateful, so he gives him a step up, hello, everyone, there is no need to make things go wrong.

After all, it will be no good for anyone to have a stumble. Don’t forget that there are a group of vassal states outside, and I don’t know if Zhang Shao is OK.

Although the girls also participated, no one was good at designing coins, so they expressed their opinions.

In the end, we should adopt the most easiest plan to flatter Mu Qing.

The denomination is written on one side of the coin. For example, one qian is written on one qian, two qian is written on two qian, twenty qian is written on twenty qian. If there are only three words, the arrangement method is not symmetry, but triangle.

Yang Gan said that he had severe obsessive-compulsive disorder, with two words on the left and right, no matter where he wrote a word on the upper and lower side, the other side was still empty. No matter how he looked at it, it was uncomfortable. It was better to use a triangle, which was symmetrical and not abrupt.

As for the other side, Xia Huiwen was written for 43 years. When Yang Gan saw the numbers, he sighed.
