Benford's law, a "fun" law discovered by Frank Benford......

In many kinds of statistics, the frequency of the nine numbers "1-9" is not average, the frequency of "1" is the highest, which can reach 30%, and then decreases in turn, and the lowest "9" is only about 5%!

With the exception of completely random numbers and sequential data such as numbers, almost all statistics in the decimal system conform to this rule.

Including birth rate, death rate, physical constants, chemical constants...... Naturally, this also includes account data!

As for the principle......

Some data types can be explained, and some data types are not known for the time being, but from a purely usable point of view, this is the most basic way to tell if the data has been altered.

When Zhang Chunhua first saw the "One Most Law" in the book in the library, he still felt inexplicable, how could there be such a thing? It can't be scribbled, right?

Later, Zhang Chunhua tested it with his family's accounts and found that in some irrelevant accounts, the data rules did conform to this law.

Even...... Zhang Chunhua also found by the way that some accounts that do not conform to this law often cannot withstand scrutiny!

The Ministry of Household Affairs has long been training in the "income and expenditure accounting method", which is not only more efficient, but also ...... Compared with the bookkeeping method popularized by Baitu, the way of making false accounts has been seriously outdated, so a careful inspection will always find some loopholes.

After all, the previous account books, in Bai Tu's view, are basically "confused accounts", and it is easier to cheat, and the counterfeiters who are used to this environment will be crushed by the new bookkeeping and auditing methods for a long time.

When he was checking the accounts in Fuyang just now, Zhang Chunhua was indeed just flipping through it casually.

However, after a general look, the pattern of "1-9" in the data was easily found!

Some of them are the most typical fake accounts, and the data is mostly incoherent numbers such as four, five, six and seven - from a psychological point of view, humans will instinctively feel that four, five, six and seven are safer, and other numbers are "too big" or "too small".

In addition, there are others, and the probability of "1-9" occurring is equilibrium......

It shows that the person who makes false accounts has excellent psychological quality, is completely unaffected by subjective factors, and is different from ordinary people, but ...... It's a pity that it still doesn't conform to the "law of one most", so it was also found out by Zhang Chunhua.

And from the characteristics of the two fake accounts, Zhang Chunhua can easily judge that the ones that are "different from ordinary people" should be from Jia Xu's handwriting!

Judging from the type of accounts, this is exactly the case - net accounts such as the loss of military supplies and the registration of war trophies.

In contrast, the other stack of accounts is much more tasteless, and some of them even have been used on the people......

Zhang Chunhua used the income and expenditure accounting method to easily find the uneven income and expenditure, and put the stack aside.

"These guys are not important now, after submitting evidence, there will naturally be people from the Ministry of Officials and the Criminal Department to deal with them." Zhang Chunhua said disgustedly.

"Well, the lord's six divisions are very good." Jia Xu said with his eyes half-open and half-closed.

"That's right, but these accounts ...... It seems that it can only be submitted to the Privy Council......" Zhang Chunhua said deliberately to the other stack.

"So...... What exactly does Zhang Gongcao want to do? Jia Xu asked in a tone that pretended not to understand.

However, what Jia Xu didn't expect was that Zhang Chunhua stood up directly at this time, walked directly opposite Jia Xu, bowed to the end and said: "When I entered the office, I felt that I was arrogant and ugly before...... I hope that 'Mr. Jia' will be able to teach me in the future." ”

Jia Xu: !!

Even Jia Xu, who had always been unable to change the face of Mount Tai collapsed, was stunned when he saw this scene......

I didn't expect Zhang Chunhua to have such an idea?

However, in the next few seconds, Jia Xu thought of more than Zhang Chunhua!

Zhang Chunhua just looked at Jia Xu's resume, and felt that this old fox not only had a talent that could be called "terrifying", but also had the ability to live with light and dust that he dreamed of......

Compared with Zhang Chunhua, who is a woman, Jia Xu is the planner of the difficulty in Guanzhong and the gravedigger of the Han family...... of the brain, he should be more regarded as a heretic!

However, Jia Xu can minimize his sense of existence, and hold important positions in the General's Mansion in a grand manner, even if some "outsiders" are dissatisfied with it, but Jia Xu has Bai Tu's trust and subordinates' compliance, and there is no need to care about others, and ...... Jia Xu can also quietly reduce his "hatred value".

Zhang Chunhua felt that if he could learn Jia Xu's six or seven skills, plus his own complementary abilities, it would be enough to dominate the world, and even if the General's Mansion went further, it was expected to become the third female duke in the future......

But what Jia Xu thought about was something else.

In Jia Xu's intelligence, the "female official" is already related to the "inner house" of the general's mansion, so if Zhang Chunhua wants to apprentice, could it be that he should be pulled to be a reinforcement from the foreign court?

Perhaps for some "thoughtful" people, it is a very beneficial thing to be able to have a relationship with the harem of the main family - after all, there are people in the harem who blow the pillow side wind, which is also a good help for foreign courtiers.

However...... This also means standing in line, which means that in the future, we will participate in the battle of relatives and even the battle of the prince!

For Jia Xu, this is obviously not a good thing, so he frowned and said: "Zhang Gongcao misunderstood, an old and old man, with chaotic thinking, and the lord will not give up, so he gave ideas to the generals in the army, how can he be Zhang Gongcao's teacher." ”

Jia Xu directly rejected the request, which sounded more dangerous than "fake accounts were discovered"!

"The teacher thinks that if I submit these to the Privy Council, I will probably not be punished heavily, right?" Zhang Chunhua called the teacher with a smile.

"Naturally, the Lord will make a clear decision." Jia Xu is not a stubble.

"No, if I go to the Privy Council, I think so, too, but...... If I am a woman, if I am sincere in my meritorious service, I will make this matter public without authorization, which will cause other troops to be dissatisfied or something...... I think I'm just going to be removed from my job because I'm not doing well.

Of course, with the character of the lord, I believe that he will not take the teacher well, at most it is idle, after all, there is no teacher and there are still Lu Sibu and Chen Sibu, but they are just ...... With what the teacher did before, it would be very troublesome if he was idle, right? Some people may not want to be as comfortable as a teacher. Zhang Chunhua continued to smile.

When Jia Xu heard this, he opened his eyes slightly and said, "Zhang Gongcao, why is this difficult? The Zhang family itself is also a big clan in Hanoi, and after cultivating with the lord of Qin and Jin, even if the background is not good for the time being, it is ...... In the future, when the lord swallows mountains and rivers angrily, the northern clan will definitely take Zhang Gongcao as Xuanhe, why do you have to drag me, an old man, into the water? ”

Zhang Chunhua was stunned when he heard this, then his face turned red, and his eyes were the same as when he first saw Bai Tu, and he stood up and said, "Phew! Old man, who did you listen to? And to the front? ”

Jia Xu obviously doesn't think it's a rumor, even if the person concerned refutes it......

Anyway, his true nature has been exposed, Zhang Chunhua immediately looked at Jia Xu, and directly threatened: "Old man, you can't accept my student, give me a happy word!" ”
