Infrastructure masters in the red building

In the room filled with the aroma of ink, the artisans of the bookstore had already designed the layout according to the requirements, and handed it over to Jia Fang for review. Then the two of them put their heads together and began to discuss the anti-counterfeiting issue of this "circulation coupon".

The circulating coupons are not big, one inch and five cents long and four inches wide.In the middle, there are three characters of "circulation certificate" written in official script, and next to it is the currency value of the circulation certificate, which is currently tentatively designated as five, ten, fifty and one hundred.The bottom is blank, ready to print the label.Next to the position of the number is a line of small characters: "Issued by the Taoyuanzhai Financial Office", followed by the year and year of that year.In order to match the name of Taoyuan Village, Jia Fang also suggested printing peach blossoms on the circulation coupons. The craftsmen patted their chests and said it was no problem-it seems that they have quite a lot of patterns like peach blossoms.

Jia Fang first discussed with the craftsmen to "overprint" - that is, to use several colors to print.This kind of technology is a bit complicated to say, but it has developed quite maturely here in Shufang.

The old craftsman introduced it to Jia Fang, saying that this technique is called "Print Arched Flower", which is a multi-plate color separation overprint, and it is specially used for printing prints in combination with the arched flower technique using concave-convex technology.The craftsman also showed Jia Fang the picture album that was being printed in the bookshop. The flowers, birds, insects and fish on it were lifelike, and the colors were moist and natural.

Jia Fang was immediately relieved, and then asked: "How is the micro-engraving and micro-printing technology in Guishufang?"

When the old craftsman heard Jia Fang mentioning this, his eyes lit up and he led Jia Fang to another room in the bookstore.When Jia Fang passed by the main room, he looked around curiously, and saw Shui Xian was half sitting and half reclining, leaning on a rocking chair, reading a book in his hand, looking relaxed and enjoying himself.

Immediately, Jia Fang was taken into another room by the old craftsman, and he saw that the light in the room was dim, and the windows were covered with thick bamboo curtains, except for the table in front of which was lit like a bean.A middle-aged craftsman was sitting in front of the case, holding a pair of tweezers in his left hand and a carving knife in his right hand, and was carving an object as small as a grain of rice.

"This is the micro-carving and micro-printing of our workshop." The old craftsman pointed to Jia Fang, "I will embed this fine plate on the whole plate later, and the printed characters are as thin as a hair, and can only be seen clearly with a magnifying glass."

"A magnifying glass?" Jia Fang's sharp eyes saw what the middle-aged craftsman was holding - it looked like a magnifying glass polished with crystal.Such things should already exist in this era, but they cannot be mass-produced without industrialization.

"Very good, color registration and micro-printing are available. But I have to ask you, can your workshop achieve these technologies?" Jia Fang knew that with these two, the anti-counterfeiting level of circulation coupons in the Taoyuanzhai area was already high. With a full score, as far as Taoyuanzhai is concerned, he is not worried at all that someone will counterfeit this "circulation coupon".

But who said that this circulation coupon is only used in the Taoyuanzhai area?Perhaps the surrounding towns will use this currency in the future.For the future, Jia Fang still decided to put all kinds of anti-counterfeiting measures in place as much as possible when launching this "new" currency at the beginning.

The old craftsman in the bookstore was very surprised when he heard what Jia Fang said, and asked: "Young master, where did you hear this? Embedding thread and colored silk in paper can change... change color." ink?"

The three technologies mentioned by Jia Fang are: security thread technology, colored fiber technology, and optically variable ink technology.

Security thread, as the name suggests, is to embed relatively thin metal wires into banknotes.As for the colored fibers, special colored fibers are added to the pulp during the papermaking process, so that the paper itself has an anti-counterfeiting effect.

As for the optically variable ink technology, it is naturally the technology that the printing ink can change different colors under different light.

These are very common in later generations, but as soon as Jia Fang said it, the old craftsman's face immediately changed color. After thinking for a long time, he murmured: "I have never heard of it, I have never heard of it..."

"This time... I kind of believe that you are really not printing paper money."

The anti-counterfeiting technology introduced by Jia Fang directly starts from the link of papermaking, which cannot be fully realized by printing alone.

The old craftsman was finally convinced, and murmured: "Young master...you know a lot!"

At this time, Shui Xian came in and said to the old craftsman: "Old man Shu, don't worry about the paper, just prepare the overprinting and micro-printing that you just mentioned. Inquire among colleagues to see if there is such a thing. In terms of paper, you don’t need to ask at all.”

Shui Xian had been reading outside just now, and seemed to have no interest in Jia Fang's matter at all, but now it seems that he heard every conversation between Jia Fang and the old craftsman surnamed Shu clearly.

"Yes, yes!" Carpenter Shu seemed to be in awe of Shui Xian, "It must be ready as soon as possible, as soon as possible."

He still has a question at the end: "But printing this paper money... no, paper money, it takes so much work, and you have to use the best paper, in case the cost of each sheet is higher than five or ten cents ...then what should we do?"

But Jia Fang said: "It's okay, just use the best materials, and I will pay you according to the price."

Since he prints banknotes, the value of the currency is not directly related to the cost of the banknotes, but mainly depends on the amount of money he puts in, the amount of reserves in his "Taoyuanzhai Financial Office", and the money he has placed in Taoyuanzhai. How about credibility.

However, Shui Xian said warmly to Shu Jiang: "This matter does not need to be profitable, you just need to settle the cost and labor, and quote a price to me. If you do a good job, I will also reward you, but the premise is that you do it really well." good--"

Craftsman Shu shivered, and clasped his fists at Shui Xian in response.

"Another thing, what Young Master Jia said to you just now must be rotten in your heart, and you must not mention half a word to the outside world. You will forget about the paper from now on. If I hear the slightest rumor from you in the future ...you should know the consequences."

Shui Xian's voice was still gentle, but Carpenter Shu shivered and continued to cup his fists: "Yes! Little man...keep it in mind."

After arranging the confidentiality work, Shui Xian grabbed Jia Fang and took him out, saying: "Zi Fang, you were a little careless just now."

"There is no need to tell the printer about the paper, and vice versa. In this way, even if someone finds out the secret of one of the two, it cannot be completely imitated."

Jia Fang nodded and said, "I see!"

He thought for a while and then added: "I believe that Carpenter Shu... Besides, even if someone really imitates it in the future, we can still come up with better anti-counterfeiting methods here."

Technology is being upgraded step by step. Since the emergence of banknotes in history, there has always been the problem of counterfeiting. Therefore, the anti-counterfeiting technology of this coin will gradually develop to that of later generations.The technical development of counterfeiting and piracy will also promote the continuous development of anti-counterfeiting technology.

Jia Fang is not worried about this at all. What he is doing now is just to improve the anti-counterfeiting level of this new thing at the very beginning, so that it has a high starting point.

Hearing what Jia Fang said, Shui Xian nodded thoughtfully.

"As for the paper, I will think of a way. But if your batch of 'notes' need to be used urgently, I have a way."

"I received a batch of paper a while ago, which was produced by a certain paper mill in the south. This paper mill was originally a good one, and only a few hundred dollars a year was made of high-quality tribute paper. But then the boss passed away, and the paper mill If there are only unworthy descendants in the house, the workshop will fail immediately.”

"So you bought this paper shop?" Jia Fang asked.

Shui Xian shook his head: "I bought all the [-]-dollar tribute paper produced in the last batch."

Jia Fang already understood what Shui Xian meant, and said, "I understand. You mean, this batch of paper is already unique, and it is absolutely impossible for someone to copy it exactly like this?"

Shui Xian nodded.

Jia Fang thought for a while and said: "It should be done. As long as the paper is durable and won't fade after printing the pattern, it should be done. The amount of banknotes I need is not too large. After all, there are only 5000 people in the entire site. Need How many coins can be calculated."

Shui Xian looked at Jia Fang with some doubts: "Can it be calculated?"

Jia Fang could only touch the back of his head: "If you insist on me, I'll have to find a way."

If he had to calculate the appropriate money supply, he had to go back to the garden to find books on money and finance.

"In this way, I will look for one or two reliable paper mills now. According to what you said, I will consider adding safety threads and multicolored silk to the paper to see what the paper is like. Wait until you print new ones next year. When we have money, we can use new paper to print." Shui Xian was extremely enthusiastic about this matter, "When the matter of the paper workshop is settled in the future, I will ask Zi Fang to help me with these details."

Jia Fang was very grateful for his enthusiasm, and cupped his hands at the other party: "It should be, thank you!"

He sort of guessed what Shui Xian meant: if banknotes could be successfully promoted in his small "experimental field", then Shui Xian would also consider promoting them in other places.

Jia Fang didn't mind at all.

But Shui Xian seemed a little concerned about his indifference, stared at him for a while, then closed his eyes, sighed, and said, "I'll take you out."

Taoyuanzhai inspection captain Wang Erlang has passed his busiest period of time.

Up to now, both the natives of Taoyuan Village and the immigrants of Xinyu Village, the first village, the second village and the third village have all gone through the initial adaptation period. Only 21 days, the longest will not exceed one month.

During this month, Wang Erlang and his good friend Zhao Wuguang, who "do not know each other without fighting", will each lead an inspection team to patrol the village every day at the "critical time period", dedicated to helping the villagers form good hygiene habits .From time to time, they also organize young people to carry out activities of "elimination of snails", and strive to have no trace of snails in all the waters under the jurisdiction of Taoyuan Village.

In this way, with the passage of time, as the patients in Xinyu villages recovered day by day, Wang Erlang's inspection team became more and more idle.

The villagers are now accustomed to the various requirements Jia Fang put forward. People and livestock do not mix baths, do not enter the river beach to bathe casually, and no one outside the public toilet forgets to wash their hands.

Some women learned how to make fragrant soap by themselves, and went to the "Sancun Canteen" to get some waste oil, and then went to the market to buy some caustic soda and came back to make their own soap, adding some fragrant flowers to it, and the pancreas produced was worth a few cents. It sold well for a small amount of money, and it became a standard item for every household.

The only pity that Xinyu villagers felt was that the farmyard manure could no longer be used—Jia Fang strictly forbade the Xinyu immigrants from using farmyard manure, but insisted that all the farmyard manure should be collected in a large brick pond to make " Harmless" treatment.

Jia Fang also gave this pool a name, "Biogas Pool". In addition to farm manure, straw and pig manure were piled in it, saying it was for "fermentation".

Wang Erlang became more and more confused.But Jia Fang really led people to seal the biogas pool, and installed a strange pointer - Jia Fang said it was a pressure gauge, and the villagers should take care of it all the time no matter what. Once the pressure is high, they must open it. The air valve lowers the pressure, otherwise the pool may be like firecrackers set off during the New Year's Eve—"Bang!"

Wang Erlang imagined it out of thin air, such a big firecracker filled with these "materials", blowing up into the sky out of thin air... The picture is too beautiful to imagine.He still decided that he, the inspection captain, should take the lead and check the pressure gauge every day.

But who would have thought that within two days, Jia Fang would say that the pressure was up and it could be used? ——Wang Erlang didn't understand what was going on, he saw Jia Fang brought a few people, laid a few pipes next to the biogas pool, and built a big stove.As soon as the valve is opened and the ignition is lit, it is really a raging fire.

This incident caused a sensation in Taoyuan Village. People from the whole Taoyuan Village came to watch, and they all felt that the flame burned surprisingly pure, and the flames were so blue that there was no black smoke.

Wang Erlang was surrounded by a group of women from the same village, chattering and discussing: "Could it be Tianhuo!"

"You are stupid! How could it be a sky fire that came out of that biogas pond? It is clearly an earth fire—"

"..."

"But whatever it is, use it as a stove, so we don't have to chop firewood now?"

"Yeah, you don't have to be covered in black smoke every time you light the stove."

Wang Erlang was proud now, and said to the women around him: "You don't know this, do you? Mr. Jia made it very clear that it is 'methane gas'."

"This swamp gas is actually the bubbles that come out of the swamp—it looks like bubbles to us, but they are all flammable and ignite at once. Mr. Jia said that he just built a pond. Simulate the environment in those swamps, and then collect these bubbles together, and when the bubbles accumulate a lot, you can light them up and cook."

The women laughed together when they heard it: "Yes...the smell of that pool is the same as that of the stagnant water, it smells dead."

Wang Erlang: "Yes!"

In fact, Jia Fang also explained what the name of this "Qi" is, but Wang Erlang can't remember it alive, he only vaguely remembers the same surname as Jia Fang and Jia Sanye, also called Jia, Jia or something-it seems to be called Jia Wan! (methane)

But Mr. Jia's surname is Jia, so he shouldn't just curse them that the Jia family is about to end!

So this is not a matter of much certainty, and Wang Erlang didn't dare to talk about it, so he could only continue to draw big cakes for the villagers: "Jia Sanye also said that in the future, the biogas from the biogas pool can also be used to light street lamps. Folks don’t have to be afraid of walking at night, there are street lights at night!”

The benefit of street lamps is obviously very attractive to women: "It's a good relationship! If you visit at night, you won't be afraid of falling into the ditch."

"Tsk tsk tsk, look at Mr. Jia, who has done so many things for us, and brought people to do them himself. Where can parents do this?"

"Yes……"

There are also people with different brain circuits, thinking of other things: "There are street lights at night? Then I can sign up for night school?"

A group of women turned around in unison, looked at Wang Erlang, and asked in unison, "Erlang, how about the night school?"

Taoyuanzhai now has literacy classes in Xiaoxiang Academy, and classes are held for adults in the evening.So no matter the aborigines or new immigrants, they call this "night school".

The reason why this literacy class is so popular is that Jia Fang made rumors that if he wants to "eat the emperor's food" in this Taoyuan Village in the future and make a job, he must pass an exam and get a certificate called "Basic Cultural Education Diploma" .Without this, you can't get on the job.

There are so many ambitious old, middle-aged and young people in Taoyuan Village. They heard that this test is also a test of literacy and arithmetic, so they took the test together.After the first test, I cried a few times.

Later, Mr. Zhang from Xiaoxiang Academy explained to everyone: To pass this exam, you must know five hundred to one thousand common Chinese characters, have a certain language organization ability, and have completed "Basic Arithmetic" and mastered addition, subtraction, multiplication, and division. Four calculations, coupled with the understanding of Taoyuan Village's regulations and common sense of hygiene, you can pass.

For this reason, Xiaoxiang Academy set up literacy classes and arithmetic classes for everyone, and went to various villages from time to time to give lectures on various regulations and hygiene.

When someone asked about it, Wang Erlang laughed and said, "Evening school? Of course evening school is good!"

He was deeply ashamed: he, Wang Erlang, really went to school for a few days and could read a few words.Coupled with the fact that he speaks in an orderly manner and does things in a methodical manner, he was often praised as "promising" in Yujiang Township.

As soon as he arrived in Taoyuan Village this time, he was "handpicked" by Jia Fang and became the captain of the inspection team. Although he was not a high-ranking official, he sounded quite prestigious.

Unexpectedly, when he passed the "diploma examination" for the first time, he couldn't find the north at all, and stared blankly at the paper in a daze, and finally came out without even daring to write his name.

So now he has to study in night school and prepare for the diploma exam? ——But Wang Erlang is not in a hurry: Anyway, Mr. Jia said that this diploma exam is not like the imperial examination outside. The exam here is held every two months. If you think you have completed your studies, you will take the exam.

He must get this diploma before Zhao Wuguang.

Just as he was thinking about it, someone called him: "Wang Erlang, Mr. Jia is looking for you, and I want you to call Zhao Wuguang, and the two of you will go to the Taoyuan Village Office together."

The Taoyuan Village Office is actually the home of the head of Taoyuan Village.When Jia Fang came to Taoyuan Village, he liked to go to his house the most, and also liked to eat the meals cooked by Mrs. Tao, and eventually the village office was set up there.

Wang Erlang responded loudly, went to find Zhao Wuguang, and the two rushed to Taoyuan Village together.On the way, Zhao Wuguang couldn't suppress his joy, and said to Wang Erlang, "I heard that Mr. Jia is going to give us an 'inspection allowance' again."
