Chapter 68 Data Flow

……

In the study room of the East Warm Pavilion of the Qianqing Palace, including Shen Yijun, the head of the household department, there were eight courtiers who belonged to the Hanlin Academy. One by one, they were sweating profusely on the desk, or scratching their hair, or showing a bitter face, and were writing some very strange symbols on rice paper with fly-headed letters.

Zhao Zhe had never taught a student, and he spent the night in the Four Seasons Spring last night under the repeated request of Cai Guyan's fox charmer. Because of the Heart Sutra of Yu Nu, his spirit is getting stronger and stronger. I woke up in the middle of the night, bored and wrote a math book with only about 1,000 words, all of which were simple addition, subtraction, multiplication and division, and at most a decimal point.

After Cai Guyan, who was extremely tired in the morning, got up and waited for breakfast, Zhao Zhe taught her the content of the booklet. She is an extremely intelligent woman herself, and she was born from a fallen scholarly family with some arithmetic skills, and she has been in a state of study for the last few months. Although those mathematical symbols and numbers were a little strange to her, they quickly remembered them in her mind because she was young. In just one morning, I learned the booklet. Next, you just need to understand it and you can put it into practice.

Then, Zhao Zhe will find some problems in the process of teaching Cai Guyan. The booklet was revised again. She retypeset and wrote a copy with a good-looking teeny little letter. He hurried back to the palace in the afternoon, and announced that Shen Yijun and some officials of the Hanlin Academy were coming.

After a brief teaching to them, they learned on their own. Actually, it's okay, the ministers who can get this step can get mixed up, if they are so uneducated that they can't even do the arithmetic of addition, subtraction, multiplication and division, they can directly pull them out and cut off their heads.

Just memorizing and writing those symbols and all kinds of rules that are different from traditional arithmetic gives them a headache. But soon, most of them, including Shen Yijun, had roughly understood.

But then, Zhao Zhe didn't let them go away. Instead, they were given the task of making a table with new symbols. A table of population, farmers, fields, annual grain production, and more.

Reading it was the first time for them, Zhao Zhe was still a little sympathetic, and asked them to make a brief general list.

Zhao Zhe, who came through the time, now has the most headache not to read those splendid articles, but to read the gorgeous rhetoric. It's the things about the data, such as the ledgers, such as the quantitative descriptions, that make him feel the urge to cut off people's heads the most.

How good are the tables in modern mathematics? At a glance, it is clear. It is not only conducive to writing statistics, but also clear at a glance. On top of that, it's easy to calculate various data models. Whether it is an official or an emperor, Zhao Zhe, as long as he remembers the data in his head, he can have a clear understanding of the country's operation.

For people like Zhao Zhe who have gone to school and work. It doesn't matter if it's a company or a country. A large and complex data model must be built. Many things, as long as the data changes before and after, you can immediately know whether it is good or bad. And many things can only be spoken by data.

Just talk about taxes, if there is a detailed list of taxes. So as long as you compare the tables of last year and this year, you can see whether the country is rising, or what is wrong, and then there is a survey and analysis of surnames, find out the crux of the problem, and prescribe the right medicine. In this way, it will be much easier to deal with national affairs, not only simple, but also very clear in concept.

For another example, for some local officials who are far away from the emperor of the sky, as long as they dispatch a spy agency, secretly sample the support rate of the people in various industries for their parents and officials, and produce a data table of the support rate of the people under the jurisdiction of the local officials. Zhao Zhe could easily judge whether the official was qualified or not.

Another example is to establish and improve a basic data table for a certain place, and update it statistically once a year, just look at the changes between various data. You can confirm their achievements and abilities.

In the long run, this will be very good for the whole country. But promoting the data model is definitely not a matter of one or two days, a year or two years. Zhao Zhe didn't expect to see obvious results in the short term.

It took the whole afternoon not to mention, but also to take Shen Yijun and the gang of Hanlin Courtyard into the first half of the night. It wasn't until a sub-hour later that they each compiled a rough data table.

Wait for them to check their respective forms, find faults, or even recalculate them. And so on until the sky is dark. It's a simple form that's okay.

Zhao Zhe only took a few minutes, and after reading the table, he had some impressions of some of the surfaces and agriculture of the Great Zhao Empire. Total population: 131 million. Total grain fields: 320 million mu. Total population of rural households: 100 million. Total annual grain production: 576 million quintals. State grain tax revenue: 17.3 billion quintals, equivalent to 86.5 million copper coins.

Zhao Zhe groaned, took a pen and calculated it himself, and then asked the officials who were already sleepy and drowsy: "In this way, the per capita annual income of a peasant household with a population of 100 million can reach about four quintals of grain. Previously, Shen Aiqing told me that including the elderly, children, and women in their prime, if the per capita annual consumption is 1.5 quintals, they can basically eat their bellies. It seems that my life as a peasant is not as bad as I imagined. ”

Shen Yijun poured a sip of tea fiercely, lifted his spirits, and replied, "Your Majesty, you don't know anything. Today's grain fields are mostly concentrated in the hands of landlords. And the landlord extracts grain and rent, which is more ruthless than the government. Thanks to the emperor's teaching of new mathematics, Wei Chen has already roughly calculated it just now. Purely in terms of the peasant population, an average of only 1.7 quintals of grain can be produced a year. ”

"One point seven quintals, one hundred seven quintals." Zhao Zhe's face seemed to be gradually becoming a little ugly. On the surface, it seems that one point and seven quintals can feed everyone. But that's just an average. He also knew to some extent that some fertile land of fish and rice would always produce more than the barren land. And the average is just barely enough to make people satisfied. In other words, a large number of peasants, after a year of hard work, may not be able to eat enough every day.

Shen Yijun, the head of the household, was not in vain, and it seemed that the emperor seemed to be interested in having an in-depth understanding of the agricultural foundation. Then he explained eloquently: "Your Majesty, the poor people also have their own way of life. Needless to say, it's self-explanatory. As the saying goes, relying on the mountains to eat the mountains, relying on the water to eat the water. You can also get some food, chop some firewood, net some fish, or raise some poultry and so on. More or less, it can also be used to supplement some household use. The vast majority of people are just living a little harder and hungry. After a pause, his face seemed to be a little ashamed, and he sighed and said, "But this is just a normal year." Once various natural disasters occur[***], many poor people will run out of food and will not be able to live a long time. ”
