The Chongwen Museum has the most ancient books, and the types of books here are very diverse, ranging from strategic history books to books on geography and agriculture.

Compared with the classics that Guozijian likes among some scholars, the books here are more comprehensive.

Yan Shigu looked to be in his fifties, and there was white hair in a neat bun that could not be hidden.

Zhang Yang saluted slightly, "I've seen Old Yan."

Yan Shigu nodded and said, "There are a lot of rumors about you in Chang'an City, and the old man has also heard it, and I also heard that you were just a homeless person in Chang'an City before?"

Smiling helplessly, Zhang Yang explained: "When the war was raging, I left my hometown and came to Chang'an City to make a living."

Yan Shigu nodded again, "Actually, there are many people like you in Chang'an City."

This didn't sound right, and Zhang Yang was puzzled: "What does the old gentleman mean by this?"

Yan Shigu put the scroll in his hand on the bookshelf, "The old man is already old, and he has naturally seen more people than you, and you are the luckiest and most successful of them."

Looking at the other party's expression, I don't know why I always don't have a good impression of this kind of person, and my speech is always prickly, a bit preachy.

Yan Shigu continued, "Chang'an City is prosperous, and there are more powerful and famous people living in Chang'an City.

With that, he took care of himself and left.

Zhang Da'an hurriedly took down the scrolls that Yan Shigu had placed on the bookshelf at random, and then put them on the ground where they should be, "There are more than 30 bookshelves here, but it will be very troublesome to find them again if they are misplaced, Mr. Yan is always like this, placing books at will."

Looking at Yan Shigu's back, Zhang Yang felt indescribably awkward in his heart.

Zhang Da'an stepped forward and looked at him, "I heard that Yan Shigu is very opposed to the imperial examination, he has always looked down on the children of the poor family when he was a bachelor of the Hongwen Pavilion before, and Shangguan Yi has been treated harshly by him."

Zhang Yang leaned against the door and nodded.

"There are also people in the secretary and supervisor who rumored that even if Yan Shigu is a businessman or a powerful child who doesn't learn anything, he can't look down on the students who have studied hard in the poor family."

"Well, I've been to the secretary and prison, and I heard that Tang Guan is there."

"This man has such a temperament." Zhang Da'an also held his hands, "Since he came to the East Palace, this person is indeed very knowledgeable, whether it is speaking and interpreting characters or specializing in those obscure classics, he can speak a unique point of view."

"Has he ever been mean to you again?"

When Zhang Yang asked, Zhang Da'an thought about it first, and then replied: "No, he often talks about his father, saying that he admires his father very much, and he can't say that he can't blame him, he often compares himself with me and my eldest brother."

"Elephant Zhang?"

Zhang Da'an nodded.

"What is the comparison between you and Brother Elephant, besides, you are not people who can do things in one field at all."

"Yan Shigu is indeed a very old-fashioned person." Zhang Da'an sighed, "In his old man's heart, it seems that he already has a brand for everyone, no matter what the other party's words and deeds are, or how knowledgeable, he only needs to take out a sign from his heart to confirm what kind of person you are, no matter what you say or do in the future, it will be such an impression in his heart."

"I get it, I just like to label people, and it's very stereotypical."

"That's exactly what it means." Zhang Da'an replied.

Looking at the East Palace again, Li Anyan stood straight at the door, with a straight face, Zhang Yang retracted his gaze, "Has the prince been exercising recently?"

"There's always been sandbags."

"You can help me find some books related to geography, and it would be better if there were classics about Nanzhao."

"Brother, wait a minute, this will be fetched."

Zhang Yang stood in the Chongwen Temple, picked up a stone on the ground and drew three circles, which represented gold, silver and copper respectively.

First of all, we must confirm one thing, that is, how far the mining of copper and silver mines in the Central Plains has reached.

Zhang Da'an came out with a pile of scrolls, "Find these first, and then I'll do that."

Go find it."

Sitting in front of the door, Zhang Yang picked up a book and looked at it.

From the beginning of the Warring States period, "Yu Gong" has a description of geography and nature, but it is very limited.

Then there is the Classic of Mountains and Seas, if you change to the children of the family and Confucian students, they will think that the Classic of Mountains and Seas is just a miscellaneous book.

However, when you take a closer look at the Classic of Mountains and Seas, you will find that there are actually many natural depictions of mountains and rivers in the records of the Classic of Mountains and Seas.

Putting down a book, Zhang Yang picked up another volume, this book is the Water Scripture Note, the description of geography in the Water Book Note is more detailed, but most of the knowledge recorded in this book is water conservancy.

Because the Commentary on the Book of Water is a work of the Later Han Dynasty, after reading Sima Qian's Book of Rivers, I feel that there are many references to the Book of Canals in the description of the Notes on the Book of Water.

Sima Qian, who was a late bloomer in his later years, deserves to be amazing.

Zhang Da'an walked out of the Chongwen Pavilion with a few more books, "Zhang Shilang is here, there are gazetteers related to Wuyue and Lingnan, and many of them mention the Nanzhao area."

Wrapping the more than a dozen books in front of him in a package, Zhang Yang carried them on his shoulder, "You usually look at the prince more, Yan Shigu is this person......

Zhang Da'an replied: "Keep your distance, but also abide by your own bottom line, don't innocently anger his old man, if there is anything wrong, I will still remind the prince below."

"Much smarter, you'll be able to answer now."

"I have time to talk with Chief Xu often, and I can also gain something."

Hearing that it was Chief Xu, Zhang Yang looked left and right, what about others?

Zhang Da'an said: "I said that I was going to take a rest in the East Palace, and I should wake up at this hour."

There was a previous incident, but I couldn't stand this long-spoken official who spoke so tightly and tightly.

Zhang Yang said as he walked with the package: "You don't need to tell Chief Xu that I have been here, and also inform the prince that Lishan will step up the printing of that extracurricular reading book to ensure that this book will be spread throughout all states and counties."

"Brother, walk slowly."

I walked out of the East Palace quickly, and I breathed a sigh of relief.

Walking all the way from the imperial city, there were only officials in a hurry who came and went on the road.

Looking at his etiquette department again, only Li Baiyao was sitting in it, dozing off.

I don't want to tie my subordinates too tightly, if everyone only listens to one person, it will inevitably be hindered in many places.

Let Zhang Daxiang, Xu Jingzong, and Zhang Dasu each take a team to do things.

Thinking about it at this time, they should still be talking with the envoys of various countries, or some people from the Western Regions in Chang'an City are inquiring about the news.

Let them take the team to do things, each team has its own direction, the Western Regions, Nanzhao, and Liaodong can be carried out simultaneously.

It's not just about efficiency, it's about teamwork and competition with each other.

Individual abilities can also be amplified in the team, and can also play a role in influencing and learning for individuals.

Xu Jingzong is a guy who does things with his own style, especially good at making friends, and it is counterproductive for this kind of person to give him too many constraints.

Li Shimin was looking at a vacant lot in the harem, listening to Yan Liben's plan for the Taiye Pool, and changed the 600 acres of land into a Taiye Pool.

After hearing Yan Liben's words, Li Shimin said in a low voice, "Let's postpone this matter a little longer."

Yan Liben said, "Your Majesty, the rainy season has passed, and if you miss this season, you can only wait for next year."

Li Shimin nodded, "I understand."

Yan Liben bowed and said, "The minister will put away the map first."

Seeing that Li Junxian was coming, Li Shimin whispered, "You should step back first."

Looking back at Li Junxian, who was trotting all the way, Yan Liben had no choice but to retreat.

Still looking at the scenery in front of him, the more Li Shimin looked at this desolate place, the more he disliked it, and he didn't like the current Taiji Palace, and wanted to build another palace, but how much money and manpower would be spent in this way.

Knowing that Zhang Yang planned to build Lishan, Li Shimin was very envious in his heart, Lishan could be rebuilt, but I was there

You can't build a palace at will, and even if you have the idea, you will be admonished.

The matter of letting Yan Liben plan the Taiye Pool had to be put on hold for the time being.

Li Junxian handed over a piece of music, "Your Majesty, this is a record of Zhang Yang's actions recently, they have transported some silver mines from the Wa Kingdom, and they are now sent to a workshop in Chang'an City."

"Silver mines? A silver mine owned by the Japanese state?"

Li Junxian opened his mouth and said, "I will continue to investigate."

It was April Day, and Cheng Chumo felt unwell in the past two days, and was telling about what had happened recently.

Cheng Yanjin also listened with a tangled face.

"The child didn't want to touch these silver mines, but Zhang Yang kept pestering, and only took a small piece of it." As he spoke, Cheng Chumo took out a piece of silver ore and put it on the table.

"Just a small piece?"

"The child does not dare to take more."

Seeing that Cheng Jin's old face gradually darkened, Cheng Chumo hurriedly said, "The child knows that this is a big matter, so he naturally doesn't dare to take more."

[At present, it is the most complete and best app for listening to books, integrating 4 major speech synthesis engines, over 100 kinds of timbres, and it supports offline reading

Scribes were sent to ask the counties and counties to submit gazetteers."

After Li Tai left.

Li Yue looked at the scrolls in his hand, and then said, "After reading so many scrolls, there is no record of the Nanzhao Copper Mine."

Zhang Yang nodded solemnly.

"Although there is no record in the classics, it does not mean that some eucalyptus records are not in the records, and if you can enter my father's library, there may be some clues."

"Your father has a library?"

Li Yue nodded, "When I was a child in the Qin Palace, my father asked people to arrange this book collection place, but at that time, he had been fighting with Prince Yin openly and secretly, and he had no time to take care of that place."

As the couple spoke, the warrior came in a hurry, "Your Majesty is here."

When Li Yue heard this, he put away his notes, and then looked at the map with a solemn face.

Seeing Li Shimin approaching, Zhang Yang and Li Yue saluted together, "I don't know if Your Majesty is far away......

"No need to be polite, I didn't want to disturb the people in the village when I came, so I didn't tell you."

Immediately interrupted the words, first looked around, Li Shimin saw a bowl of brown sugar water and drank it, "I was really thirsty when I came, and the flavor of this brown sugar is really good."

I wanted to remind him that it was leftover from Li Tai's drink, as if he didn't care.

Li Shimin was still reminiscing, "I heard that you took a lot of gazetteer classics from the East Palace, originally to draw maps?"

Li Yue whispered: "It is true that there are many places that I don't understand on the map, especially the geographical boundaries of these border towns are very unclear."

"This map is much clearer than the map in my palace, and Tubo is also included in the territory, you kid really has the heart to take Tubo, I didn't mistake you."

"Your Majesty has praised it."

Li Shimin asked again, "How sure are you that you will take Tubo?"

Zhang Yang explained, "The minister must do his best."
