As for the complicated patterns on the ticket, they are all freely swiped by carving masters and others. Li Yu gave the overall idea: "The more complex the better, the better, it is best to be able to achieve the level of dazzling things that make people look at it at first glance."

The complex and exquisite patterns of promissory notes under such guiding ideology are simply a sublimation of the printing industry in the Southern Tang Dynasty. With the two-color overprinting, promissory notes look like handicrafts.

But even so, it still cannot stop counterfeiters.

Li Yu carefully observed the promissory note presented by Han Dong, and Pan Chenghou and Feng Rusong were also explaining softly.

I have to say that the imitation level of this promissory note is extremely high, using authentic Chengxintang paper, and the complex patterns are outlined with a guitou pen.

At a glance, there is almost no difference between it and the real one. No wonder big businessmen like Han Dong are fooled.

"Han Dong, come here," said Li Yu.

Han Dong shrank forward timidly, and Li Yu said quietly: "This promissory note is indeed a fake."

"Pu" Han Dong's knees softened and fell to the ground again. "King, these 100,000 yuan are all the wealth of a villain..."

"I also asked my fellow villagers that I borrowed some. If I couldn't exchange it, villain, villain..." He could not continue to speak for a few consecutive calls to the villain, but he knew that this fake promissory note could not be exchanged for copper coins. He could have made a fuss, but there were two kings sitting on it. What would happen if he made a fuss?

I was so angry that I handed Zhang Mingshen to Jiangning County. Not to mention the issue of 100,000 yuan in money, it is hard to say whether my life can be saved.

"But, Han Dong, this matter has always turned around. You can go through the incident in a few ways and don't hide anything. The more you say it carefully, the faster you can find out the real murderer, and you can avoid losing everything."

"Ah?" Han Dong suddenly saw hope, wiped his face with his sleeves, and showed a look of careful thinking.

Li Yu waved his hand and asked someone to give him a hot towel.

After Han Dong wiped his face, his expression gradually became normal.

Li Yu looked at it again. Han Dong was in his thirties and was quite heroic, but he had a hint of the shrewd temperament of a businessman. That strange man could earn a huge fortune at a young age, but it would be extremely difficult to move up to this scale.

This person is really flexible. He immediately joined Li Jingcheng's disciple, but he was still on the periphery and was not a core member.

"It's so let King Anding know that this is the case."

In Han Dong's narration, the ins and outs of this fake vote gradually appeared in front of everyone.

However, what surprised Li Yu the most was that this fake ticket was actually sold!

In other words, this promissory note was not something that Han Dong himself saved in the semicolon outside Jiangning, but he received the ticket from Jiangning City General Account to withdraw the money.

It is the payment given to him by someone else after he sold a batch of goods.

In other words, in just one month, merchants have begun to use it as a quasi-currency!

"...Whoever says that only Jews can do business and understand finance, I will be anxious with them... The sensitivity of the merchants in Nantang is so terrible!"

So he asked someone to give him a cup of tea. Although he wanted to know the details of the circulation of promissory notes, he still asked Han Dong to focus on the fake notes.

Unexpectedly, we still have to go around this circulation aspect.

It turned out that Dechang Palace Bank was only three days after it was officially opened, and these businessmen saw the huge benefits.

In order to verify its credibility, many businessmen would rather pay a few chunks of handling fees than try it out by themselves.

Jiangning and Jiangdu are only half a day away, and the first batch of Dechang Palace Bank's business is the verification of it by merchants.

Several merchants gathered 10,000 yuan to Jiangning General Number in the morning and went to Jiangdu Branch to collect the next day.

In fact, according to their intention, it is best to extract it that afternoon to verify its credibility.

However, when Li Yu formulated the details, he specifically considered noting that unless it was a local deposit and withdrawal, there would be a delay of varying days.

The purpose is to give enough time between the general number and the semicolon to pass and check the account book.

The holder does not get the money by stuffing the promissory note into the counter. The promissory note and the account book must be checked at the counter. The payment will only be made after the two are completely consistent.

Suppose someone saved 50,000 stags of money in the Wuchang semicolon and took a promissory note marked "Wu 8384".

After the Wuchang Association's business ends, it sorts out the detailed information of all the bills issued on that day and copies it into seven copies. Each of the four shops has one copy as the basis for accounting. The other three copies are entered into the general account archive, Chengxintang, and the provincial eunuchs.

The eunuch was purely for Li Jing to see. After all, it was his money. Of course, he had to know whether he was looking at it or not, but Li Yu had to implement the rules in place. In the daily operation of Dechang Palace, he had no idea of ​​stealing from it, in order to be open and fair.

After all, what banks value most is credibility, and the accumulation of credibility begins with countless trivial things.

As for the Chengxintang, Chengxintang is the largest archive in the Southern Tang Dynasty, managing all archives in the inner and outer courts.

In fact, Pan Chenghou had already arranged his confidant and made forms and drawing diagrams based on these information.

If you do this, you can't see any results in a day or two. Over time, you can learn from the commercial exhibitions of these four cities from the side.

After all, it was the feudal era, and the management of internal affairs was far from being meticulous. The numbers in the local officials' newspapers were mostly based on them. In the past, the calculation power was insufficient and it was impossible to review it.

Now that the abacus and calculation center are available, it can effectively increase the difficulty of cheating in local governments.

The data of Dechang Palace promissory notes can also be used as an important means of review or verification.

Assuming that Nandu Left Behind said that the city gate tax this year has dropped significantly compared with previous years, but the number and unit amount of promissory notes have increased significantly. In this way, the data of the two will be in conflict, and Nandu Left Behind can be asked to explain.

This is also the reason why all the staff of Dechang Palace insisted on using eunuchs - they only obeyed the emperor and the chief and deputy palace envoys, and local officials could not even birds.

Li Yu did not tell Li Jing about Chengxintang's data analysis at the beginning, but instead showed Li Jing a complete set of analysis tables and icons directly after twenty days.

The latter suddenly seemed to open the door to a new world. The data of Nandu and Wuchang semicolons were just a hasty look at it, but they asked Dongdu in detail. Then they ordered Li Yu to continue doing it, especially the data sorting and analysis of Jiangdu was the top priority.

Li Jing's reasons are also very good. Jiangdu is not only a major commercial center in the world, but also a military center for fighting the pseudo-Han and Wuyue. Of course, the court should pay more attention to it. Once the data is incorrect, it must be reported in a timely manner.

Li Yu naturally took the order and left.

It's gone far.

This system of account and ticket verification is the biggest difference between promissory notes and the prosperous Tang Dynasty flying money. It is also the fundamental reason why the former can be exhibited on a large scale, while the latter can only be a small fuss for individuals.

When the business volume increases significantly, searching for data on a unified format account book is more convenient and quicker than one by one.

As for the timely transmission of invoice data, it is a huge problem for most people in this era, even a wealthy businessman with a business of hundreds of thousands of yuan.

But Li Yu was the prince and Dechang Palace was the emperor's private money, so he used the post station system openly.

Anyway, it is now in the Southern Tang Dynasty, and the post station is used to convey official documents every day.

It’s not a big deal to add a few more urgent delivery every day. At worst, you can hire a few postmen and buy a few postmen.

Just now, Han Dong took this promissory note to withdraw 100,000 guan of money. When the shopkeeper checked, he found that there was no such amount in the account book.

He was suddenly panicked and searched through the account book again, but it didn't appear.

When the shopkeeper saw this, he hurriedly asked someone to go to the archive to check the original files around the date of opening the bill, and naturally he found nothing.

Then I looked at the bill carefully and confirmed its number, which does not comply with internal regulations.

The numbering rules were also created by Li Yu, and they directly abandoned the practice of re-shui numbers, because this would easily allow those who are interested to infer the business volume of Dechang Palace based on the numbers, so economic data naturally must be strictly kept confidential.

Therefore, the four businesses each have their own numbering rules and will be replaced every once in a while, which is another anti-counterfeiting method.

What makes this fake ticket eventually reveal is the numbering rules. Chengxintang paper can be stolen, and color printing can be hard-printed with a pen.

But in terms of numbering rules, unless there is an insider, counterfeiters can basically not get around this iron threshold.

Han Dong received this fake ticket in Jiangdu. Now in Jiangdu and Jiangning transactions, promissory notes are very popular as large-scale payment methods. After all, I have tested credit before, and merchants feel that it is unbelievable to do business with two wooden boards {plyboards that protect promissory notes} in their arms.

Han Dong originally thought he was lucky. He originally sold a batch of copper materials from Nandu to Jiangdu, which was also the center of the copper industry. The bronze Buddha statues and copper incense burners he cast were all the most meticulous in the world.

Jurong, not far from the river, actually produces copper. However, in recent years, Jurong has sold less and less copper materials on the market. The copper regulator said that the minerals are exhausted, but it is still recruiting miners regularly.

So everyone has a tacit understanding and will not mention this matter anymore.

Originally, Han Dong's old customer suddenly couldn't find anyone this time.

Of course, there will never be any concerns about the lack of sales in copper. Han Dong plans to find a few big workshops to sell the goods.

But he was called out on the street. He thought he had a good memory, but he couldn't recognize the person who greeted him.

But the man was very enthusiastic and directly pulled him into the best restaurant. During the conversation, the man said that he met at a banquet and said that he was inseparable from the names and personalities of the attendees.

At that big banquet, Han Dong drank a little too much, and finally slipped away from the table. He really couldn't recall all the diners.

Seeing what he said so sincerely, I believed it in my heart.

In addition, the bulk goods were finally transported to the ground safely, and I felt relieved. At this moment, I naturally felt even more relaxed when I met an old friend in a foreign land.

The man was generous and ordered the whole table to eat. It is said that he used a new iron pot from Gong Zhongming, which was cooked by stir-frying. It was fresh, fragrant and delicious.

Han Dong has been in the army for several years and is also very heroic. Seeing that the other party’s enthusiasm is not as good as a fake, he also relaxed his mind and started to eat and drink.

The man was quite familiar with Han Dong's circle of daily relationships. He blurted out someone's habits and character, and then added a few mean words to comment, which immediately made Han Dong feel like a close friend.

As he was talking, he talked about the issue of buying and selling. Han Dong said that he brought a ship of copper material.

The man's eyes lit up and said that he had opened two copper workshops recently and had a good master dug from several old houses. At present, Jiang is short of copper. Han Dong's cargo is just sleepy and falling off his pillow.

Then he directly sold a promissory note of 100,000 yuan to be regarded as a deposit. Han Dong's cargo was originally planned to sell 110,000 yuan.

Seeing that the other party was so happy, the ship of cargo changed hands without saying a word.

As for the difference, the other party also gave it to him after completing the delivery procedures.

Han Dong is also a person who is used to trading and has been paying attention to promissory notes, but he may not have any fraud.

It was not until today that I realized that Dao'er was caught and suddenly she was in tears.

After Han Dong finished speaking, he looked at Li Yu pitifully. Everyone here knew his thoughts. After years of savings were destroyed, he was naturally unwilling to accept it.

Li Yu also understood, but he waved his hand and asked the eunuch to take Han Dong down to rest.
To be continued...
