Liu Qichang was a cautious man, and if he wanted to withhold the relief grain, he would naturally make all kinds of hands and feet seamless, and he claimed that he could collect the grain distribution books for Wang Xijue to inspect, precisely because he was convinced that there would be no flaws in these books.

In order to facilitate management, the village chiefs generally take people to the prefectures and counties to collect them. Liu Qichang's method was to ask the prefectures and counties to do a good job of the distribution of grain first, but when it came to the distribution quantity, it was extremely sloppy and specious. For example, the officials gave 10 loads of grain to a village, and the book said "10". After the chief drew away, the scribe added a few more strokes of "one" and changed it to "five", so that 10 quintals became 50 quintals, and the 40 quintals of grain that were left in the middle naturally fell into the pockets of the officials.

If someone really wants to investigate a famous hall like this, they will naturally be able to find out, and as long as they take the book and confront the chief who receives the grain, they will be able to find out the problems. But in order to do this, the investigators had to go to various villages and towns, but this kind of hard work was something that those court officials were unwilling to do. Liu Qichang is well versed in officialdom, so he dares to hide from the world like this.

Hearing Liu Qichang keep saying that he would collect the book of disaster relief grain for inspection, Wang Xijue shook his head with a smile and said: "This is too troublesome, when the old man chatted with Gaizhi a few days ago, he said that he knew about it, why don't you let Gaizhi talk about it?" ”

"Su Gaizhi......" Liu Qichang's face changed suddenly, and he turned his eyes to Su Hao, who was sitting on the side.

"Governor Liu, take the liberty of it, in fact, the official didn't plan to ask about the disaster relief grain the year before last, but the soldiers under my command lived in the village, and listened to some village farmers' chatter, and listened to a few more words. As you know, these soldiers can't hold anything in their hearts. After hearing about this, he reported it to the official, so the official knew that there was such a thing. Governor Liu, don't think that this official is deliberately trying to embarrass Governor Liu......" Su Hao stood up and said a lot of nonsense first.

Liu Qichang can be said to be angry with Su Hao but dare not speak, Runing's case finally ended with Su Hao's victory, what Liu Qichang can do is just barely protect himself, in front of Su Hao, he has no prestige. Now that he heard that Su Hao had put his hand in the disaster relief food two years ago, Liu Qichang couldn't help but be shocked. He waved his hand and said: "Master Su's words are wrong, you are a senior official sent by the imperial court, and if you want to visit the old man's words and deeds, it is all within his responsibility, how dare the old man have any complaints." ”

"Well, Governor Liu is so reasonable, it really makes the younger generations admire." Su Hao said with a bit of ridicule, since Liu Qichang called himself an old man, he simply regarded himself as a junior. He turned. Said to Wang Xijue: "Elder Wang, the lower official asks the elder to allow the bookkeeping of the lower official and Mr. Wu Zhicheng of the Runing Academy of Sciences to be present to make a statement. ”

"Yes." Wang Xijue had already been angry with Su Hao and knew what Su Hao was going to do next.

Su Hao walked out of the lobby and said hello, and after a while, he came in with an old master and a young woman. He introduced it to the crowd. This old master's name is Wu Zhicheng, a great Confucian, and he is now working in the Runing Academy of Sciences run by the prince of Chongwang; The young woman's name was Cheng Yi, and she was the bookkeeper in the survey camp. The officials in the hall were not interested in Wu Zhicheng. looked at Cheng Yi quite curiously, because in that year, it was rare for a woman to be able to take a position in the army. Not to mention taking on a technical position like bookkeeping.

"Ladies and gentlemen, the little woman is the bookkeeper in the public opinion camp, and I am ordered by Master Su to report to you the results of my survey of the public opinion camp in the prefectures and counties of Runing, and I ask you to agree." Cheng Yi said generously to the officials that she was originally born in a family of eunuchs, and she was no stranger to this kind of occasion, and she did not have a sense of stage fright.

"Miss Cheng, say it." Wang Jiaping said with a smile.

"Master Xie." Cheng Yi saluted Wang Jiaping, and then said: "Some time ago, in order to thoroughly investigate the occupation of rural land by Runing Hao, Master Su sent officers and soldiers of the Survey Battalion to the villages of various prefectures and counties to visit the villagers. When asked about the imperial court's disaster relief two years ago, many villagers said that they had indeed received relief food at that time. ”

"Oh? So, can you prove the innocence of Governor Liu? Wang Jiaping felt a little surprised, he originally thought that the people brought by Su Hao should be unfavorable to Liu Qichang, but he didn't expect Cheng Yi to come up and endorse Liu Qichang, saying that the villagers had received relief food.

Cheng Yi smiled slightly and said, "Don't be anxious, my lord. I asked the villagers how much grain each household had received at that time, and some of them said that they had received a load, and some said that they had received six or seven buckets. ”

"That's for sure." Liu Qichang interjected, "The population of each household is not the same, and the situation of the disaster is also different, so it is not surprising that the food received is more or less. ”

Cheng Yi ignored Liu Qichang's explanation, but continued: "In order to find out how much grain was distributed in Runing Mansion, we did a sample survey in various states and counties according to Master Su's instructions. ”

"Sample survey?" Wang Jiaping was a little confused, "What is sampling?" ”

"It's up to the old man to explain this, right?" Wu Zhicheng, the old master who couldn't help but want to speak, hurriedly said, "This sampling is the meaning of extracting a few people from the crowd, as long as the sampling is skillful, from just a few hundred people, you can calculate the situation of hundreds of trillions of people, saving time and effort, and foolproof." ”

As a geologist, Su Hao is very proficient in sampling surveys, of course, the sampling he did in his previous life was for geological phenomena. As early as in Fengcheng, in order to get rid of Wu Zhicheng's entanglement, Su Hao compiled several mathematical pamphlets for Wu Zhicheng, which also included the content of simple probability theory. Wu Zhicheng is worthy of being a great Confucian, he has thoroughly eaten these books compiled by Su Hao, and he has drawn inferences from one another, and has mastered the technique of sampling investigation.

Liu Qichang embezzled disaster relief grain, and the specific amount is difficult to find out from the account books. However, the disaster relief grain will eventually be distributed to the peasants, and if the relief grain received by the peasants can be calculated clearly, then the amount of Liu Qichang's embezzlement can be pushed out in turn.

There are hundreds of thousands of peasant families in Runing Prefecture, and it is not possible in terms of time and cost to ask them one by one how much grain they received that year. But this kind of thing is difficult for Su Hao, he directly designed a sampling plan, and selected in various states and counties according to several levels, and finally obtained the appearance of more than 1,000 farmers. Based on the process of calculating the sum of these samples, he directly handed it over to Wu Zhicheng to do, and Old Master Wu was full of interest in such things.

Many people are aware of the ability to reflect the big picture through sampling. However, the extent to which the sampling results can represent the overall situation and how much error there will be when sampling samples is not something that can be judged by experience alone, and some mathematical statistics calculations need to be made. Wu Zhicheng, inspired by Su Hao, has mastered this calculation method, at this time, with a bit of a pretentious mentality, he introduced his calculation results to everyone.

"According to the old calculations, the disaster relief grain distributed by the entire Runing Mansion is between 19,000 and 23,000, and there is no accident." Wu Zhicheng said with an oath.

Wow...... Hearing Wu Zhicheng's calculations, Liu Qichang gasped. This figure is exactly the amount of relief food he actually distributed. He originally thought that if others wanted to figure out this number, they had to visit all the people who received food, but he didn't expect Wu Zhicheng to calculate the results through more than 1,000 samples, what kind of skill is this.

"Governor Liu, is what Mr. Wu said true?" Wang Xijue asked Liu Qichang lightly.

"This ...... Forgive the officials for disagreeing. Liu Qichang said, "Mr. Wu's knowledge must be extremely profound, but what kind of sampling is this...... The lower officials don't know what He Shengxian created. ”

"The old man has a little faith in the results of Mr. Wu's calculations." Wang Xijue said, "I heard Mr. Wu say just now that the disaster relief grain distributed in the entire Runing Mansion was actually only 19,000 to 23,000 quintals, and the old man suddenly remembered, and they found out that there was indeed an account of 78,000 quintals of grain in the booklet of the Toyama Grain Store, and the origin was unknown. Governor Liu, do you want to send the shopkeeper of Fushan Grain Store and ask, where did his 78,000 quintals of grain come from? ”

Liu Qichang's back was covered with sweat, and he replied sneeringly: "This matter...... The lower officials really didn't know about this matter, and the elder of the pavilion intended to pass on the shopkeeper of the rich mountain grain store, and the lower officials ......"

"Smack!" Wang Xijue suddenly slapped the table and shouted: "Liu Qichang, so far, you still want to deny it!" To tell you the truth, the grain receipt books forged by you and the governors of the prefectures and counties below have already been inspected by this official. Instead, the official found some lieutenants who received grain that year, and after they looked at the book, they all said that the number of grain received that year was wrong. Do you think that you are doing things carefully on your own, don't you know the truth that Skynet is magnificent, and negligence is not leaked? ”

"Xiaguan...... Wronged! Liu Qichang couldn't care about Sven anymore, so he knelt down on the spot with a plop, and said with tears in his eyes: "The lower officials have no choice but to do it themselves." The main reason for deducting the disaster relief grain is to get those farmers to voluntarily hand over the fields in their hands, and those fields are not occupied by the lower officials themselves, but there are really other people. ”

Now, Liu Qichang knows that paper can't contain fire. The vicious Su Hao counted out the amount of grain that Liu Qichang embezzled, and if Wang Xijue wanted to investigate further, Liu Qichang would not be able to hide it at all. He had no choice but to resort to one last move, that is, to pull the tiger skin to make a banner.

"Who do you say there is someone else?" Wang Xijue asked angrily.

"It's King Chong!" Liu Qichang replied loudly.
