In fact, the Hu Han merchants in Ningyuan are no longer just bartering. Copper coins, gold, silver, silk, and cloth are all used as currency.

With such a large market, they no longer only require barter and appropriate prices, and can also accept transactions of gold, silver or silk cloth. With these, they can still buy the goods they want from Han merchants, and even buy them with them, which is even more popular.

The gold and silver coins minted by Li Ji Money House are exquisitely made, difficult to imitate, and have a standard denomination, and are very popular among Turkish merchants. Turkish merchants often trade some gold, silver and pearls, but these have to be identified first and agreed upon the value.

"Carry more gold and silver, and we also open a coin minting workshop in Ningyuan to mint gold and silver coins. Don't mint copper coins in the future. Now the court has started to mint coins."

Li Shimin was so poor that he made money everywhere.

After Li Chao talked about the advantages of coin minting last time, Li Chao became concerned. Using the hydraulic coin minting method mentioned by Li Chao, the cost savings are a lot, especially time savings and expanding production capacity. Criticizing coins can also become a very profitable method and can increase the income of the court, so naturally we cannot let it go.

Besides, after adopting the new method of minting, it will be a big blow to counterfeit coins. After all, the difficulty of imitating this kind of minting has increased greatly. Li Shimin has made all the molds and a large mint has been built on the Wei River in Chang'an.

The newly minted money is called Zhenguan Tongbao, because the court has already discussed it, and next year is the first year of Zhenguan. Of course, the money from the Zhenguan Dynasty cannot be called Kaiyuan Tongbao anymore. After all, the newly minted money is different from Kaiyuan Tongbao.

The weight of Zhenguan Tongbao is the same as that of Kaiyuan Tongbao. It weighs one coin, but the copper content is reduced. However, because Li Chao said that the newly cast copper coins are difficult to imitate, it is not very important to reduce the quality even if they are reduced.

In the past, the imperial court reduced the copper content of coins and even issued directly what to do if it is five or ten, and issued iron coins, but the result was a chaos. Why?

The biggest reason is that these coins are not difficult to imitate. The lower the copper content of the imperial court coins, the higher the profit of minting fake money, and of course the more fake money.

The copper content of Kaiyuan Tongbao is very high. Putting aside the minting coins, the copper contained in the coins has even exceeded the value of the coins themselves. Those illegal merchants directly melted the copper coins. The copper made of monoxide can be sold for six or seven coins, six times the profit.

In history, in the Song Dynasty, it was popular.

It is often counted as seven hundred and six hundred coins as one thousand coins. Why is this? Because at that time, people calculated based on the actual value of copper coins. The copper contained in six hundred coins was worth one thousand coins, so they saved money.

This is no longer using the monetary value of money, but directly using its own metal value.

Of course, no one is willing to imitate such good money. If one loses one, who imitates it. Everyone makes fake money, inferior money, but those who are too inferior are easily recognized, they will be rejected, and they will be reported to the officials when they are found, and the government will severely punish them if they are found.

Therefore, if the government uses money well, the credit system of coins can still be maintained.

Once the government uses the difference in money, even one is worth ten or twenty, and latte is used as money, it will be over. Because the threshold for imitation is too low, and even others do not need to make bad money, they can do exactly the same as the money of the court, the same materials and the same craftsmanship.

Because no matter how hard you do it, you won’t lose money.

Who knows if such money is leaked?

A large amount of private money appeared, which was equivalent to robbing the imperial court of seigniorship.

And now, Li Chao is just like a cheat.

The new coin minting method allows the court to avoid the expensive minting cost, and can be used to reduce the cost of materials and have a lower quality. This way, the cost will be reduced and the manpower and time will be spent.

But because of the new technology, it is extremely difficult to imitate. If they want to imitate the same as the money from the court, they will not only not be able to imitate much, but will also lose money, one by one.

If they make inferior money and imitate it casually, it will be difficult for such money to flow out under the suppression of the court. People's businessmen refuse to accept it, and the government makes a reward for reporting, and the government vigorously investigates and cracks down on it. They find that one is arrested and one is arrested and one is disposed of.

In this way, the cost of counterfeit and shoddy is so high, and fake money will naturally be difficult to circulate.

The imperial court successfully replaced the higher-cost Kaiyuan Tongbao with the lower-cost Zhenguan Tongbao. The cost was saved and it also hit illegal merchants and earned seigniorship tax.

For those merchants who want to plough copper coins to make copperware, the profit of melting money has been reduced. For those merchants who want to imitate copper coins, the cost has been increased.

If the cost of crime increases, the crime rate will of course decrease.

However, because the output of gold and silver is too small, although the court also planned to mint some commemorative gold and silver coins for rewards, it did not prohibit merchants from minting gold and silver coins themselves. After all, the small amount is mainly calculated based on the value of gold and silver itself.

The Tang Dynasty never regarded gold and silver as circulating currency.

However, this happened to be a good gap for Li Chao.

The Li family runs a money shop and has this advanced coin minting technology. Of course, the Li family will not imitate the imperial court's Zhenguan Tongbao, but using this technology to mint some gold and silver coins for circulation in the market here, how could they let it go?

When gold and silver coins were in Taozhou, they were used very well.

For the Li family, the quality of gold and silver coins is reduced a little, and the coins minted are calculated at the full value. The difference between them is their profit. For users, gold and silver are precious metals, and both Turks and Han people can accept their value. This is a kind of hard currency.

Although the quality may not be sufficient, his exquisite production is difficult to imitate, especially without weighing it, but calculated based on the face value, which makes it more convenient for merchants.

Crushing gold and silver coins is definitely a way to make money. The only thing that restricts the Li family from making money by minting coins is where to get enough gold and silver.

With gold and silver, after melting, it is mixed with copper and casting, and profits are continuous.

"Sanlang, our family has handed over the coin minting technology to His Majesty. Now that we use this technology to mint gold and silver coins, will we be taboo?" Zheng Hongxin is now considering things more and more comprehensively.

Li Chao casually looked through other reports and said, "You don't have to worry about this. When His Majesty got the coin minting technology I presented, he said that the Li family can continue to mint gold and silver coins in the future, as long as they don't mint copper coins. If you think this way, even if there is no coin minting technology, the previous gold and silver shops and jewelry stores would still make some gold leaf and gold ingots, and that can also be used as money."

"As long as your Majesty allows me, I can do it with confidence." Zheng Hongxian said with a smile, and the Li family has added another money-making industry.

After acting as a teacher for a while, after being praised by Hong Shi and Si Niang, Li Chao went back leisurely.

Zhao Siniang has been in the Li family for a long time. Li Chao has long been used to seeing her now, and he has no intention of seeing her at all. When he meets, he nods and greets him without any extra politeness.

He originally introduced several people to Zhao Siniang, all of whom were his own subordinates and all of them were of high rank, but Zhao Siniang was unwilling to do so. Li Chao would forget that he saw her like this. After all, others would have to be willing to do it as a matchmaker.

It is useless to force the cow to press his head without drinking water.

When I went back, the maid had already prepared toiletries.

There is still no toothpaste, and the tooth powder is used. The main material is green salt, and some Chinese medicinal materials such as mint powder are added. Green salt is not ordinary salt, but is made of the top green salt grains in Yanzhou and then burned with bamboo.

To show off, it is to publicize the public that the top-grade green salt from Yanzhou is packed into the three-year-old green bamboo, and seal the two ends with natural loess.

It is then used for more than ten years as fuel and then refined after calcination.

In fact, there is no need to ask for so much, just ordinary salt, ordinary green bamboo, ordinary loess, and ordinary pine branches.

To put it bluntly, this process means that bamboo will reach a high temperature of more than 1,000 degrees when it is calcined. At this high temperature, organic matter will be burned and inorganic matter will be left.

Bamboo salt is actually another form of coarse salt.

After burning, some minerals in bamboo salt are higher than ordinary salt. These things mainly come from bamboo and loess that contain more ingredients, which are baked and enter the salt.

This is actually like many skin care products and health products in later generations. There are certainly some elements and essences, but how many they have, how many they can play a role, is definitely not as good as they boast about.

After Li Chao's bamboo salt was made into powder, he added some Chinese herbal medicines such as mint, and then it became tooth powder.

After advertising in the Banyue Talk, this tooth powder immediately became a popular product for Chang'an Fugui Home. Like the perfume and soap produced by Li's family, tooth powder has also become a hot-selling product for the Li family now.

It's a very simple thing, sprinkle it on a toothbrush, and it feels cool when brushing your teeth.

After brushing my teeth and vomiting foam, my teeth are indeed white and my mouth is very cool, but it is definitely not as mysterious as advertised.

Wash your mouth and wash your face.

Be energetic.

Carrying a cowhide backpack with a few pieces of clothes inside, Li Chao was about to go to the morning swimming.

There has been no war recently, and Ningyuan City is also quite good.

In the Lingzhou area, Chu Suiliang was busy digging the Tang Canal.

The weather is hot, and there is such a good lake next to Ningyuan City, so now Li Chao has a new activity in the morning. He is to get up every morning to practice guns and then ride a horse, and then sweat.

I just went to Wuhu, and when I was sweating, I jumped off the lake to have a good time.

I swam around the lake for a while and felt extremely happy. After I had fun, I changed my clothes and rode my horse to go to work in the yamen.

As soon as he left the door, Su Dingfang was already waiting there on a horse.
