Whether to find Di Fatpang, who is still in his infancy, or whether to take him to Chang'an for training, Li Yuanjia will certainly not make a decision easily.

After all, Di Renjie's background will definitely not be bad, and his parents may not be willing to let him come.

There are naturally many reasons, for example, the child is only ** years old, who can rest assured that he came to Chang'an from Bingzhou? For example, if you, a prince of the Tang Dynasty, suddenly look for him like this, can people have no worries?

If not, what should Li Yuanjia do?

Although Li Yuanjia can use his name and power as a prince, what will be the consequences if he doesn't talk about it in that case, even if he subdues the other party? What Li Yuanjia wants is a Di Renjie who is better than in history, and definitely not a "disciple" who is respectful on the surface, but hates himself in private.

** years old children, they are already sensible.

And Li Yuanjia also has his own concerns, he is an idle king who suddenly wants to find a son of an official eunuch who has merged with the state, and he wants to bring Chang'an as a disciple, will it attract any bad discussions and lead to any bad consequences?

It's hard to say these things.

So after thinking about it, Li Yuanjia decided to put this matter aside for the time being, and first asked Han Lucheng to send someone to inquire where Di Renjie was and whose child he was...... This is definitely not difficult, because if you can achieve the position of prime minister in the future, the Di family will definitely not be unknown in Bingzhou, after all, although the imperial examination has begun in this era, it is difficult for ordinary people to sit in a high position......

Hehe.

All in all, Di Chupang must have been remembered by Li Yuanjia, even if that kid is now ten years old at most. But that's something to consider in the future, and there is still a person in Chang'an right now, so Li Yuanjia has no reason to let it go easily.

So on the second day of Han Lucheng's sycophancy, a handwritten letter was sent to Guozijian and handed over to a young man Langjun!

"King Han? That set of "Mathematics" turned out to be written by King Han?! ”

After reading this handwritten letter, the young Zhang Cambodia's eyes suddenly widened, and his mouth was open enough to stuff an egg!

Han Wang Li Yuanjia, of course he had heard of this name.

The fact that he can enter Taixue to study means that Zhang Cambodia is also a member of the "ruling class" of the Tang Dynasty, and although the land at home is not enough to be measured by fast horses, it is not a minority. So as early as the second year of Quyuan Plough's appearance, this thing appeared in Xiangyang, thousands of miles away, and entered the gate of Zhang's house in Xiangyang.

Even in agriculture, the truth that knowledge is power is vividly embodied.

In China's thousands of years of feudal history, ordinary peasants were almost always the same, and as long as it was not a war-torn era, they could hardly leave their own state...... It should be said that most people basically stay in their own counties and even villages all their lives, at most, they just go to neighboring villages for happy events and funerals.

Coupled with the fact that there is no literacy in large characters, the channels for obtaining information are almost closed...... Or at most a small opening, the local squires...... Or that the people of the clan can tell them something.

This is also the reason why in feudal society, the local squire had so much prestige and the clan system was so strong.

To put it bluntly, in the feudal era, if you wanted to obtain information, you not only had to be literate and knowledgeable, but also had enough status. Whether it is a quyuan plow or a rollover, if you want to promote it in the whole Datang, you can't even think about relying on those ordinary small farmers, you can only rely on the squires and big landlords everywhere.

And they have the most land, and these new farming tools can bring them more wealth and motivation.

So that's it, Zhang Khan Zhi knew about the existence of King Han, because many people call Quyuan plough King Han plow...... As for tables and chairs, iron pots, stir-fried vegetables, etc., he hadn't heard of them before coming to Chang'an, after all, these are not farm tools, but luxuries, and the "remote areas" in Xiangyang are not qualified to enjoy them like the magnates in Chang'an and Luoyang.

So many things, Zhang Cambodia only learned about it when he arrived in Chang'an.

For example, the famous Hanwang paper is now about to be blown into the sky by the students of Guozixue...... Speaking of which, until now, Zhang Cambodia has never seen the real Han Wang paper, and he has always regretted it.

Therefore, for the existence of King Han, Zhang Cambodia has naturally heard of it for a long time!

Merely......

Whether it is Qu Yuan plow, Han Wang's paper, or even the tables, chairs and stir-fried vegetables that he only saw after coming to Chang'an, to be honest, the impression left by this Han Wang on Zhang Cambodia is not so good.

Even if his family and himself have enjoyed the benefits of these "Han Wang", it does not mean that Zhang Cambodia will have admiration and yearning because of this.

The reason is simple, it is the education that I received from childhood.

This is more troublesome to say, in short, people of Zhang Cambodia's class value the most virtuous name and talent, but it is limited to the talent name on "learning"! Lu Ban may still be appreciated by them because of his status as a craftsman, but if this kind of talent is placed on a noble prince......

Even if the body accepted Qu Yuanli and Han Wang paper very honestly, and shouted true incense, it really didn't prevent them from their hearts or when communicating in private.

Well, that's a long way off.

Therefore, after knowing that "Mathematics" was written by King Han, Zhang Cambodia was so surprised. Because after hearing so many "legends", he had already fixed the image of King Han, and now he suddenly saw that people could write a subversive arithmetic book like "Mathematics", which was naturally extremely shocking!

And after the shock, Zhang Cambodia naturally began to ponder: "This King of Han ...... Obviously he is a nobleman of the emperor, and his status is extremely respectful, so why do you like it...... What about these things? ”

It's no wonder that Zhang Cambodia is so confused, because the course of arithmetic is actually opened, after all, one of the six arts of a gentleman still needs to be more or less understood. Even in the Guozijian, there is also the "major" of arithmetic!

It's just that compared with the fact that the children of officials above the third rank can study Guozixue, those who are above the fifth rank can enter Taixue, and those who are above the seventh rank can enter the four schools, arithmetic is mainly for the children of officials of the eighth rank and below, and there are only 30 places...... Even so, it is often not suitable for recruitment, and it needs to be supplemented by the children of the people!

And I learned to be able to write the book "Mathematics...... Even if it is a reference to Tianzhu's arithmetic, it shows that King Han has invested considerable practice and energy in arithmetic!

Why?

Scratching his head, Zhang Cambodia really couldn't figure it out.

He originally thought that it was exaggerated enough for him to secretly read these books and spend his spare time and energy on them recently, but he didn't expect a prince to be even crazier than himself!

Merely......

Even if he obviously didn't look down on the King of Han before, but after looking at the six books of "Mathematics" on the left hand side that had been read by himself, and then at the handwritten letter on the right hand that invited him to go to the palace to see him, Zhang Cambodia's eyes flashed rapidly a few times, and then slowly became brighter......
