In the study, Su Song taught Tao 17 to do arithmetic and drawing, teaching attentively, learning hard, and the atmosphere was very harmonious. Tao Qiqi is a person who loves to drill the horns of the bull, but he is quite talented in learning this. In the past two months, after the teaching of Du Zhongxiao and Su Song, he has been able to design and manufacture small parts by himself. Tao XVII found what he liked, and his life was happy.

On the other side, Du Zhongxiao crouched on the table, carefully studying various account books. He is different from others as an official, compared with the top people of this era, how to try cases, how to reassure the people, and I don't know what year and month it will take to stand out. Only by giving full play to one's own strengths and using one's brains in developing the economy and attracting the population can we outperform others. But you need money everywhere to do these things, where does the money come from? Du Zhongxiao has to figure out a way.

In the previous life, methods such as attracting investment could not be used, and the three divisions had already collected these financial rights. How to earn money and how to spend it is a problem that gives Du Zhongxiao a headache. The existing fireworks production workshop was handed over to Gu Zhi County a few years ago, and now it is back in his hands. There is also a field business, which is in the spring ploughing, and all kinds of investments and seeds are clearly stated.

After watching it for a long time, I only felt dizzy and bloated, Du Zhongxiao closed the account book and looked out the window boredly. I am now the magistrate of the county, and according to the words of my previous life, I can say that I am the master of my territory, and I can do whatever I want. This is not necessarily impossible, as long as no one is against him, no one comes to check the account book at this time, everything is easy to say. But if someone doesn't like themselves, there are loopholes everywhere.

An economic offender is a serious offender, Du Zhongxiao sighed secretly in his heart. In my previous life, I always felt that the ancient officials were very casual when it came to money, as long as they had money to hand over to the top and occasionally offered bribes, they could do whatever they wanted. How can that actually be the case? The easiest thing to make in this day and age is the economic mistakes. Not long ago, Zhang Kang and Teng Zongliang made a big fuss, and there were countless small cases.

In addition to taxes, the most important thing in a county's finances is the wine and salt merchant tax. These taxes are either fixed or proportional, and the county takes a portion of it for its own use. Yongcheng is near the Bianhe River, commerce is developed, and the imperial court is strict and heavy, and there is not much left for the locality.

Now Du Zhongxiao's biggest headache is in what name to develop the industry, that is, to need a carrier. In his previous life, this was called a clear property relationship, but at this time, it was the lack of a prefecture treasury that was completely controlled. The government at all levels manages its finances through various treasury accounts. The warehouse not only includes all kinds of physical warehouses, but also the place where various economic matters are accounted for.

Standing up, Du Zhongxiao went behind Su Song and Tao Qiqi and saw that they were drawing a few cylinders on paper. This is a model used to study the juxtaposition of cylinder piston motion, power, and vapor pressure and temperature. For the steam engine, this is a key step in theory, and the relationship between pressure and volume and temperature difference is clear, and there will be a direction for improvement in the future. Du Zhongxiao, a simple physical formula, naturally remembered that now it was necessary for Su Song and others to understand, and make various instruments and conduct sufficient tests.

The pen used by Tao 17 is a pencil, made of graphite crushed and mixed with yellow clay, and it is very simple to know the principle. Paper was a bit troublesome, because paper at this time was evolving to adapt to ink, and it was not friendly to pencil drawing, so it had to be replaced with pressed wax paper.

Looking at Tao Qiqi's painting, Du Zhongxiao pointed to a few cylinders and said, "This needs to be extremely smooth, what do you want to do?" ”

Tao Seventeen said: "There was a machine outside, fixed there with a cutter head, shaking this cylinder liner and turning it, and it will always be smooth." ”

Du Zhongxiao said with a smile: "Where is the knife pinned?" You should use a set leather or satin instead of a knife head for grinding. This kind of thing has to be tried again and again to be done well. Take a break and drink two cups of tea. ”

Tao Shi agreed, put down the pen, leaned on the table with his cheeks on his cheeks, looking at the drawings and thinking about Du Zhongxiao's words.

Su Song knew that Du Zhongxiao had something to ask, so he stood up and went outside the room with Du Zhongxiao.

Looking at the red, green and green flowers and trees in the yard, Du Zhongxiao sighed and said: "I am now governing a county, and the most difficult thing is to cultivate fields nearby and solicit household registration. There is another thing, there are many things that his subordinates are in charge of, and there is the case of Ma Meng first, and it is strictly forbidden for his subordinates to accept bribes and bend the law for bribes. But the people under him do things, and many people have no money, and they can't drink the northwest wind to live. I have a way to make money, but I have never figured out how to get the money in and out. There are also military depots and ministers' depots in the state, and there are many names that can do these things, but it is difficult for the county to do them. ”

Su Song thought for a moment and said with a smile: "What can this do!" The camp is not one place, as long as it is a separate account. The county can set up a permanent library, dedicated to all kinds of field affairs, and the surplus is to make up for all kinds of miscellaneous donations, not from the people. As for the county officials, it is enough to build a reward library. It's all ancient, but it's just abandoned now. As long as it is done well, which can gossip! ”

Du Zhongxiao's eyes lit up, this is also a solution. Needless to say, Changping has existed since the Han Dynasty, but now many places exist in name only. Although many of these repositories are located in counties, it does not mean that they cannot be set up in counties. The Reward Library turned out to be the Inner Library, which was used for the emperor's support of the army, and it was inappropriate to use this name directly. However, with reference to this system, it is not impossible to set up a separate library.

The purpose of building a library is not to put things, but to take accounts. Without these, you will have your own private small treasury to earn, and it is difficult to tell when you check it. With a few special-purpose vaults, businesses can be set up in the name of the vaults, and the money earned is sent out from the vaults.

Su Song's words provided Du Zhongxiao with an idea that he could refer to some libraries of the state, road, and even the imperial court to make accounts in the county. In the end, the county is also a first-level financial unit, and no one says that it can only manage the finances of a few banks.

As for the field affairs, in fact, they can be accounted for separately, and as long as they are not mixed with ordinary households, the accounts can be cleared.

One of the most troublesome things about these accounts is that they can't be mixed with Du Zhongxiao's own income, otherwise there will be trouble. After all, theoretically, an official's income in office can only be paid, and other income must have a clear source. For example, officials who do business cannot do business under their rule, but they are still allowed to sell goods in other places, but they have to pay taxes as well, and these accounts must be clear and not confused with public accounts.

Sighing, Du Zhongxiao smiled bitterly and shook his head. In fact, as a normal official, you don't have to be so clear with yourself, and no one usually says anything if you take advantage of it. It's just that I have crossed thousands of years, and I am too confident in my ability to make money, and I don't want to leave anyone with any handle on money, so I make such trouble. This is their own trouble, and others only look at it with envy.

Looking back at Tao Seventeen, who was still lying on the table, Du Zhongxiao said: "Since I have eyebrows, I don't bother about this matter anymore." While you're still in the county, let's take a closer look at the steam engine. It has been two or three years since the machine was made, and it has been of no practical use. It would be a good thing if it could really be used before you left. ”

Su Song said: "In the past few months, I have discussed with you how to increase the strength of the machine, and I have a lot of experience. With a little more force, you may be able to make a machine that can be used. I used to discuss this thing with Han Zhongyun, and I thought about loading it on the ship. I think these days, in fact, it can be installed in the car. ”

Du Zhongxiao smiled when he heard this: "Since it can be loaded on the ship, of course it can also be loaded on the car." It's just that the car was a little too big. ”

The steam engine can not only pull trains, but also as tractors, and of course, large trucks. It's just that the car is huge, and the road conditions don't allow it. Such a behemoth can be completely abolished after a few good trips.
