The official took someone to move the colored cotton on the car, and Xu Ping instructed: "According to the previous instructions, you must try each one in the same way, don't mess up everything together, and in the end you can't see what it looks like." Pen, fun, pavilion www. biquge。 info”

The official promised and took people to prepare.

Doing experiments is a technical job, from the beginning to what to achieve, how to arrange, how to deal with the results, and what conclusions to draw in the end, it is difficult for people who have not carried out relevant training to do a good job.

From the time when he decided to set up a money bank, Xu Ping set up this small workshop, specializing in making all kinds of bills needed by Jingxi Road. All the paper used for the bills is made in-house, and various paper tests are carried out at the same time. In the future, if you want to issue banknotes, Xu Ping hopes to have an answer through the experiment here.

In this year's time, I have tried almost all over the time from the commonly used 捍 paper such as Jiaozi in this era, that is, paper made of tree bark, to mulberry bark and linen hemp poles, and even fishing nets. As for the commonly used ones such as rice paper and bamboo paper, that's not to mention. Eventually, Xu Ping discovered that the best paper material for banknotes was cotton, especially the shortest cotton fibers attached to cotton seeds, which made paper that was both durable and good for printing, and suitable for handling all kinds of security marks.

This is why Xu Ping asked Wang Gongchen to pay special attention to colored cotton, if the corresponding paper can be made from colored cotton, it can be used as a special paper for banknotes in the future. This alone significantly increases the cost of making counterfeit coins.

From the day the banknotes were produced, such as Jiaozi in Yizhou, there were counterfeit money. However, the range of use of Jiaozi is limited, and it is easy to control in a relatively small interval, and it does not cause a particularly bad impact.

Paper money basically does not collapse because of counterfeit money, which only increases the cost of the paper money system. As long as the credibility of the banknotes does not collapse, counterfeit money is just a disease of ringworm. However, for banknote issuers, it is always hoped that the minimum cost will offset the cost of issuance and use of counterfeit money, so as to get the maximum benefit.

This is especially important for Xu Ping. If paper money is introduced, and as a result, there is no official income due to the flood of counterfeit money, or even negative returns, then the prospect of paper money will be clouded. It is precisely because of this that although he knows that anti-counterfeiting is not the key point of banknote issuance, Xu Ping still devotes great energy.

Watching the official take people away, Wang Gongchen said curiously: "How did Du Cao think of using cotton to make paper?" ”

"Try it out! I'm not a fairy, how do I know what is the best way to make paper? I had to try the same. In the past year, the commonly used and uncommon paper-making raw materials have been tried here, and cotton is the best. ”

Wang Gongchen looked at the huge cotton bale, and always felt that it was amazing to turn into a strong paper, and asked: "Only use cotton?" ”

Xu Ping looked at Wang Gongchen and shook his head with a smile: "Jun Zhen, you don't have to ask this, you have to be suspicious!" ”

Wang Gongchen immediately understood, such an important matter, of course, the fewer people who knew about it, the better, but there were not many people in this entire small workshop who knew the formula. But I was not happy in my heart, and I was not convinced: "I just asked casually, who wants to know this?" I only asked Du Cao, if the three divisions don't allocate copper money this year, what will happen to the debts of the camp and field affairs? I have thousands of people under my command, but I have to rely on this money to eat! Make them unhappy, how can I still make everyone work! ”

"There will be no shortage of money, and you don't have to rush at this time. Wang Bowen, the deputy envoy of salt and iron, just arrived in Xijing City, saying that he was going to worship the imperial tomb, and I think most of them came for this matter. In the end, it depends on the news after he returns to Beijing. ”

Wang Gongchen's expression softened a little, and asked Xu Ping: "Du Cao, what do you think Deputy Envoy Wang can come up with when he returns to the capital?" Can you really conjure up so many copper coins? I think it's still a bit hanging! ”

"Jun Zhen, copper coins are only one type of money, why do you only recognize this one? In the past, the copper money was not enough, and the officials had to spend it, and it was not the same? Besides, in the past, money and silk were universal, and copper coins were not enough, and there were a large number of silk silks, so couldn't they be used the same? ”

"Silk?" Wang Gongchen smiled when he heard Xu Ping's words, "Du Cao, if you don't go out to inquire, what is the price of silk now?" In the past, a horse of silk always had a lot of money, but now it is only six or seven hundred Wen, who dares to ask for it! If this is collected according to six or seven hundred wen, and after a while it becomes three or four hundred wen a horse, who will reason with it? ”

Xu Ping smiled: "Who did you listen to this?" The price of silk on Jingxi Road has not fallen so low. ”

"Yes, Henan Prefecture and nearby states and counties don't have it, but the outer counties have already fallen! It is Jingxi Road, and the price of silk in Mengzhou and Xiangzhou has fallen. I heard that all the states on Jingxi Road strictly prevented the silk silk of the state army from outside the road from being transported in, which made the price of silk not fall sharply. If this is not the case, the price of silk in Henan Mansion will also have to fall by half! ”

"Xiangzhou and Mengzhou can't do the new policy, of course, they can't be treated the same as other states and counties on Jingxi Road, and their silk prices there can only be on par with the state army outside the road. And the price of silk on Jingxi Road can't fall. ”

Wang Gongchen said strangely: "Why? If the price of your silk here is high, someone will always bring it in and sell it! ”

"When people bring in, I collect heavy taxes to see how much money they have to put into it! Originally, the price of silk fell, although there was a reason for a large number of cotton cloth on the market, but it was also because of the improper disposal of the three divisions, and it was chaotic. ”

"What do you mean by that? Can the three divisions still force the price of silk to rise? ”

"Why not? Sichuan Gorge several roads through iron money, before copper money and iron money parallel, have you ever heard of the art of weighing? It is because copper and iron coins are parallel, and the method of preventing the same expensive and cheap is used. ”

Wang Gongchen thought for a while before saying, "I seem to have heard of it, but I don't know it very well." ”

"When there are two kinds of money, when they are parallel, in order to prevent the comparison of the two prices, it is necessary to weigh them. In the Tang Dynasty, money and silk were parallel, and it was a method of using the government to forcibly stipulate the exchange ratio, which was not easy to use. What is really useful is to control the amount of money on the market, and then to regulate it officially, and to send more out when it is expensive, and collect some when it is cheap. Now in fact, the market is also money and silk in parallel, cotton cloth on the market, the price of silk silk has fallen, according to the so-called mention of the technique, the three divisions and local governments should buy silk silk, put copper coins, in order to stabilize the price of silk. Although the price of silk will always fall after the popularity of cotton cloth, it will not plummet so much, leading to countless incidents. As a result, now that the price of silk has fallen, the third division and the local government not only do not accept the silk, but also take the lead in throwing the silk silk in the library. ”

Wang Gongchen was stunned and said: "According to what you said, I'm afraid that the third division doesn't have so much money in his hands——"

"How much does it cost? Most of the silk silk is originally in the treasury of the government, how many can be on the market if it is not released? As long as the price of silk can be temporarily stabilized, it can still be used as money, where is there such a big copper money gap! So you said that you were worried that you would not have the money to pay back the field work, but I told you not to worry, now the copper money of the third division is not enough to make up for the holes, and it is enough to stabilize the price of silk for the time being. ”
