After sitting down, Liu He picked up the book that Zhang Poji had just put away from the bookshelf at hand.

This is a volume of "The Legend of the Ram".

In the "Three Biography of the Spring and Autumn Period", "The Legend of the Ram" and "The Biography of Gu Liang" are the current manifest learning, but in later generations, "The Biography of Zuo" is very popular, and it has to be said that the world is unpredictable.

Liu He read a few lines hard, but it was indeed not as vivid and interesting as "The Biography of Zuo", so he put it in its place.

"Master Zhang's book is really hard to read, and he will be able to show filial piety and honesty in the future, and at that time, Zhang Qing will be able to soar and become an official."

Liu He said flattering words, but it also flattered Zhang Poji, and he didn't even dare to say a few things.

At this time, the main way for the Han to select and appoint officials was the probation system, in addition to the various ways of recruitment, appointment, sealing and selection, but the probation system was still the right way.

Confucianism's goal in life is to "learn and excel", so Liu He's flattery naturally tickled Zhang Poji's itch.

After some pleasantries, we got to the point of today.

Zhang Poji first talked about the general situation of Changyi in the past three years.

In general, it is better than a year.

With the application of new iron farming tools and the popularization of intensive farming technology, the yield of various crops has increased to a certain extent.

Because the promotion time is not long, the planting technology has not been fully mastered by the farmers, and the yield has only increased by less than 20%, but it has made the people's lives a lot better.

When life is better, there will naturally be fewer people who have fled to the mountains, and even many displaced people who have fled to the mountains and wilderness have returned to their original villages, and the population has increased.

The increase in harvest production has increased the income from land rent; The increase in population has increased the income of the oral and arithmetic contributions by a part; Even the criminal cases and litigation disputes in the country have been reduced.

Taxes, population, and the number of prisons are the criteria for evaluating the county.

So just looking at these items, it is not a problem for Changyi to take one of the "most" in this year's big class.

Zhang Poji said as he put the slips that recorded various data in front of Liu He piece by piece.

Looking at these yellowed wood bumps, Liu He had a headache, and this was only part of the paperwork. If you want to send all the slips used in the class to Chang'an, I'm afraid you will have to use a few ox carts.

Moreover, the scope of what can be engraved on the slip is limited, and it is inevitable that the handwriting will be blurred, which makes people dizzy.

The imperial history in charge of the examination in Chang'an and the officials of the court are probably highly short-sighted.

"The items of population, taxation, and prison are all excellent, and Changyi Xiang will definitely have a good result in this big lesson."

"An Le Gong has been with us more than once, Changyi can have the current situation, it is inseparable from his subordinates, whether it is himself or the people, they will not forget the kindness of their subordinates."

An Le is today's Changyi Xiang, now over 50 years old, born in filial piety, is a sleek and capable follower.

Zhang Poji's words were not polite words, at least nine of the ten people in this Changyi country would be grateful to him—but some of them didn't know his true identity yet.

Zhang Poji is a veteran in handling cases, and he is naturally familiar with the process of the class examination, Liu He can't help too much in the specific process, but he can put forward some different opinions.

"Every big class is customized, and it has not been changed for many years, I believe that Zhang Zhushu is naturally handy, and I don't know much about the class exam, so I can't help much."

"However, I can make a few premature suggestions in the details, and see if it is beneficial."

Zhang Poji is waiting for this sentence, Liu He's suggestion does not dare to say that the situation is reversed, but at least it is a thousand words, and he can always listen to thunder in a silent place, which has been verified many times.

"In my opinion, the content to be evaluated in this big course is divided into two sides: the inside is the foundation of the surface, the surface is the skin of the inside, and the inside is interdependent." Liu He deliberately turned simple things in a complex direction.

As soon as Zhang Poji heard this first sentence, his eyes lit up, he had governed two counties and one country with Changyi, and he had experienced seven or eight regular and big lessons, and he had never heard the saying that "the outside and the inside are interdependent".

I couldn't understand it, but my curiosity had been completely aroused.

"The door has a fresh mind, please advise."

"This [li] is a summary of the specific conditions of the population, taxation and criminal prisons, and the Changyi country has had good weather in the past three years, of course, there is no need to fake."

"This [table] is the case form system that is submitted to us, and we can move our minds to let the officials of the Tingwei Mansion and the Imperial History Mansion who are in charge of the big course see the politics of Changyi State more clearly."

After Liu He finished speaking, he asked for a pen, directly drew a box on several cases, added a few horizontal and vertical lines to it, and finally added names and numbers......

"This diagram is called a table, and it has different shapes and is ever-changing, and it is best used to present content such as numbers, which is clear and clean."

Liu He said that he drew a bar chart and a pie chart on several cases, and explained the advantages and disadvantages of different charts while drawing.

Zhang Po has been involved in the case of obscenity and obscenity for more than ten years, and naturally easily sees the usefulness of the "art of charts".

"It's an artifact, it's incredible, it's incredible!" Zhang Poji is not only talking about the incredibleness of the charting technique, but also the incredibleness of Liu He.

"Where did the subordinates learn this charting technique, but there are classics for the little officials to refer to."

"Hehe, it's all my own creation, and there are no classics to refer to."

"The subordinates are really wise and intelligent, but this big lesson cannot be completed in a day and a half, and it is not very convenient for the subordinates to enter and exit the Prime Minister's Mansion, how is this good?"

"Master Zhang, rest assured, there is a Lang Zhong named Li Zhang in the palace who has fulfilled my true inheritance, I will send him over to assist you, and in addition, he will teach you this watchmaking technique without concealment."

Master Zhang was overjoyed, and hurriedly made a big gift to Liu He.

If it was Liu He a year ago, he would definitely avoid it, but now he can accept it calmly - he has to adapt to different lives in different environments.

"Don't thank me first, I still have something that can be the icing on the cake for the case of Changyi's big class."

"Please also ask your subordinates to give me advice."

"I've ever heard of something called paper."

Liu He's question is not superfluous, because there were already places in the early Han Dynasty that began to use hemp paper.

The raw material of this hemp paper is hemp fiber, although the surface is rough, but it can already be used for writing and painting.

Sure enough, Zhang Poji nodded after a little thought and said, "Not only have I heard of it, but I have also seen it." ”

"It's clearer to draw this diagram on this paper, one by one, than on this little wooden stick."

Zhang Poji was happy at first, but then frowned and said: "But this hemp paper is easy to scatter, I'm afraid it may not be easy to use." ”

Liu He was waiting for this sentence, he smiled mysteriously, and then said: "I also have a secret method that can improve the disadvantages of hemp paper, make it whiter and brighter, and greatly improve the situation of scattered ink. ”

"Please give me advice!" This is the third time in this short period of time that Zhang Poji has said this.

"That's natural, I'll let Li Zhang bring it with me, and let the engineer try to do it when the time comes."

Liu He settled the matter in this way, and then under Zhang Poji's thousand thanks, he took Yu Wuwu into the broken carriage and drove towards the north of Changyi City.

As they gradually disappeared at the end of the street, a man in his fifties, dressed in a robe and wearing a green ribbon around his waist, came behind Zhang Poji.
