I read from the accounts I have learned that there are several cattle and horses and sheep in the pastures, each with male and female, how many have been laid in March, how many have been laid in one year, how many have been laid in two years, and how many have been laid in two years, and they are clearly divided into categories. Cattle and horses even have been above ten years old and over twenty years old.

Du Zhongxiao looked at it twice, put down the account, and said to Chen Qin who was standing in front of him: "How many months have you been in charge of the ranch? How many livestock numbers can be listed so clearly. Just the ability to do accounts means that I have not read the wrong person."

Chen Qin scratched his head: "I'm not hiding the officials. How many livestock are there in the ranch? The little one is like a mirror in his heart. He will definitely answer the questions. But if he talks about the accounts, the little one really doesn't know. Even the official's account books have been filled in. How can the little ones distinguish them? This time the account was entrusted by the little one to get acquainted with Luo Jingzhi."

"Oh, I didn't expect this person to have such skills. I underestimated him a few days ago." Du Zhongxiao patted the account and pondered for a while. "You go and call him here, I have something to ask him. Being able to make the account so clearly is better than an old official in the yamen."

Chen Qin was delighted, crossed his hands and agreed, and turned around and left.

The three departments of the Song Dynasty had reached an unprecedented level of control over the national finances. In this era, the three departments must be divided into one document. The means used were accounts that were as vast as a sea of ​​books. The mathematics in this era was not well developed, and abacus was not promoted. Whether it was to produce or count such a number of accounts, it was an impossible task. For counties, the fiscal power was in the state, and almost all income and expenditures had to be calculated. To achieve this, you can only use formatted printed money and fill in numbers on the direction of the land. The same is true for counting the number of livestock in the pastures, with paper for special accounting. Correspondingly, in addition to the total amount of various livestock, there is also a sum of the total, that is, a cattle is equivalent to the total number converted after several sheep. Luo Jing made it differently, and it was classified into various categories, and it was clearly clear.

To develop the economy, we must first clearly calculate the current economic situation, and only after a period of time can we understand the effects of various policies. Otherwise, no matter how much you do, you will eventually be in a fog, and you cannot understand the details of the economy or control it at the macro level.

Du Zhongxiao has always wanted to make the economic statistics of Yongcheng. Only in this way can all his reforms be organized. Once this system is established, it will be of infinite benefit to becoming an official in the future. Unfortunately, there have been no suitable talents and his energy is limited, so he has been delayed until now.

He pulled Luo Jing out of the restaurant and Chen Qin said, "What am I saying? As long as you have the ability, the magistrate will definitely use it! I asked you to count the livestock on the ranch for me, and my husband could see that you are extraordinary at a glance and ask me to take you to see you."

Luo Jing shook his head repeatedly: "How can you know that the zhizhi County is the same as you? It is not because I wrote it, which is inconsistent with the accounts I sent before, so I have to blame you. If you don't do this, you don't know that everything in the yamen is classified. How to remember the method and can't be easily changed."

Chen Qin did not believe what Luo Jing said, but just pulled him and hurried to the county government.

After entering the official hall of Du Zhongxiao in the yamen, after seeing the ceremony, Luo Jing bowed: "I wonder what instructions do the official call the young man to come?"

Du Zhongxiao picked up a piece of paper from the table, and handed it to the servants around him, saying, "The pasture livestock you recorded is very organized and is much clearer than the previous ones. But there are some shortcomings. I will make another note. Take it back and fill in the rest according to the list on this paper. Be sure to be careful and don't make any mistakes."

Luo Jing received a piece of paper given to him by the servant and saw that it was a form drawn by Du Zhongxiao. He filled in the three good-bred horses he bought this year. He successfully mated with several horses and gave birth to many ponies. The number of ponies is divided into male and female ponies, each with a number, and each item is summed up. Unlike the previous description in text, the paper is divided into grids and filled in separately, and the statistical results of each item are clear at a glance.

Moreover, Chinese characters are no longer used on the table, but simple pictures of strange things are used instead of numbers, just like runes. Below the table, there is a line that explains what numbers the symbols above are, corresponding from zero to eleven.

After reading for a while, Luo Jing asked, "Officials, I don't know why I use this picture instead of using words?"

Du Zhongxiao said: "The original text was too complicated. If there were people who could not read, there might be some mistakes. The numbers above came from India and were introduced to the Central Plains with Buddhism, but there were not many people who knew it. I changed it a little to make it easier to write and use it to count."

"Oh——" Luo Jing nodded. He was not clear about what these scholars did, and there was no need to understand. "It seems that there are some benefits for officials to keep accounts like this. But what are the benefits and how to do it, and the smaller ones need to be careful to think about it."

"It's okay, just take it back. I'll give you three days to revise the ranch's accounts. If it's done well, I'll use it."

Luo Jing hurriedly thanked and happily put it away. He was boring in the restaurant and his income was far from comparable to Chen Qin. He was quite envious of Chen Qin. If he had a similar job, it would be great.

Just as Luo Jing and Chen Qin left, Du Zhongxiao felt aroused in his heart and asked, "Since you know how to keep accounts, can you use abacus?"

Luo Jing bowed: "I don't hide it from the official. I used to see others' uses, so I roughly knew how to use it, but I was not familiar with it."

Du Zhongxiao said: "When I was in the capital, I saw that there were stores that were very useful. It was inevitable to calculate the number of accounts. If you know how to use abacus, it would be much more convenient. If it is easy to use, go back and practice it."

Luo Jing was a little embarrassed: "If you don't hide it from officials, where can you sell things in Yongcheng County? Even if you want to learn, you can't buy them."

Du Zhongxiao didn't expect that there was no one sold in Yongcheng County, so he waved his hand and said, "That's all, just go back and handle the ranch accounts according to what I wrote."

Seeing Luo Jing and Chen Qinli go, Du Zhongxiao thought in his heart, but forgot that the abacus of this era was not popular. There are abacus of this era. Du Zhongxiao did see it in the shops in Beijing, but he didn't go to heart at that time. This thing was not difficult to make, and the reason why it was not popular was not because it could not be made or bought, but because there were not many people who could use abacus to calculate.

Whether it is developing industry or developing economics, a lot of mathematical knowledge will be used. Not to mention those complex mathematical theories, even the simplest four-point operations, there are not many people who can calculate clearly, and it is even more rare to calculate quickly and well. There are not many people in Yongcheng County. Du Zhongxiao taught Tao Shiqi Fourteen-point operations for several months, and it is still extremely difficult to calculate multiplication and division with paper and pen. This is still a talented person. If an ordinary person learns it for several years, it is normal.

In fact, compared with reading and literacy, simple mathematical knowledge is more useful and more urgent, but there are no suitable textbooks and no suitable educational institutions. Naturally, there are many types of calculation books, and now there are many. However, those calculation books must first have a certain amount of cultural knowledge to understand, and it is even more difficult to learn. If you can calculate in this era, you must first be a scholar.
