In Li Yuanjia's view, Han Lucheng's idea is indeed the right way.

The literati of ancient China were indeed a tough nut, and it was really difficult to get them to accept foreign culture. In this way, Li Yuanjia must also be glad that he has traveled to the Zhenguan period, if he waits for the Song Dynasty or even later era, it will be even more difficult to change them.

The atmosphere of Datang is still relatively much more open.

Although it is also very xenophobic, for example, Li Yuanjia's number one subordinate Yang Su once arrested the entire Hu merchants in Chang'an City for a trivial matter. And although they were released afterwards, which of those wronged Hu businessmen ever got an apology?

Don't be funny!

Our officials of Datang bullied you, that's your blessing!

So in essence, Datang, like the previous and even future dynasties, has natural self-confidence, and it is not easy for them to learn from others.

Of course, it's not easy, it's not impossible.

But this possibility will require considerable effort and a long time.

And Han Lucheng's suggestion just gave Li Yuanjia a hint: since it is difficult for literati who traditionally need to learn "mathematics" to conquer, why not consider starting from other people?

The stewards of the provinces in Chang'an City? The shopkeepers of the big shops?

No, Li Yuanjia didn't want to look for them.

At least not yet!

Although Han Lucheng was right, Li Yuanjia thought more than he said, knowing that if he directly sold Tianzhu numbers and advanced bookkeeping methods to the stewards and shopkeepers, the only outcome could only be failure!

There are two reasons, one is that they can't call the shots, and the other is that the cost is too high.

The cost factor is easy to understand, after all, not everyone can be as bewitching as Li Tai, who can master Arabic numerals and the basic four arithmetic by self-study - never overestimate the learning ability of ordinary people, and definitely not overestimate their patience. Even if Li Yuanjia writes the six books of "Mathematics" in simple terms and is as easy to understand as possible, but in the absence of any foundation at all, unless someone specially trains them, otherwise the words are utopian!

As for saying that they can't be the masters themselves, it's easy to understand, in what way to keep accounts, and the stewards can have the final say?

How can it be?!

What if they learned Arabic numerals and learned the bookkeeping methods of the Han Palace? After all, the final ledger is to be shown to the masters, and they can't understand it.

"So, the only way to do this is to take the lady's route!"

The more I thought about it, the more I felt that I was right, and Li Yuanjia's eyes suddenly brightened: "Under normal circumstances, the people who take care of the industry and manage the accounts in each government should be the ladies, right?" With Arabic numerals, it will be easier for them to settle accounts, and it will be harder for those who want to do things in the ledger, right? And compared to Fang Xuanling and Cheng Zhijie, "

The more I thought about it, the more reliable I felt, and the corners of Li Yuanjia's mouth couldn't help but curve an arc.

Roundabout route, this trick is absolutely wonderful!

Thinking about it in his heart, Li Yuanjia walked back to his small study quickly, and then unexpectedly saw Fang Fengzhu who was writing and drawing on a blank piece of paper.

Putting the index finger of his right hand to his mouth and shushing, stopping the ink painting and Si Qi from going forward to salute, Li Yuanjia walked behind Fang Fengzhu lightly, and then lowered his head to take a look, and was immediately happy.

Coincidental!

What her princess is now writing on the paper is exactly the problem of chickens and rabbits in the same cage!

A binary equation, the very simple kind, Li Yuanjia just told her in detail yesterday. But it is clear that the dear princess has not fully understood this type of question, and at this time she is writing and drawing on paper, and it seems that she is constantly looking for a trick to solve the answer!

"Whew...... That's the normal operation! ”

Seeing Fang Fengzhu's clumsy problem-solving process, Li Yuanjia secretly breathed a sigh of relief, and the confidence that was hit by Li Tai instantly recovered a lot.

That's right!

You are an ancient person, a girl more than a thousand years ago, if you are like Li Tai, you will thoroughly understand it after reading the book for a few days, and you will finish all the exercises that Li Yuanjia has done...... If that were the case, Li Yuanjiake would have to doubt his IQ.

Perhaps because she was thinking too intently, Fang Fengzhu didn't notice her husband's arrival, and kept frowning and thinking hard that whenever she had a little inspiration, she would quickly write it down on paper, and then it would be a long thought......

To be honest, from Li Yuanjia's point of view, the topic is really simple and fatal.

It's nothing more than getting two equations about x, then using the equal formula on the right to get the value of y, and then inversely deducing the value of x. If you bring a junior high school student from the future, I am afraid that you can solve this problem in more than ten seconds, or even a few seconds.

But looking at Fang Fengzhu's posture, it's like facing the last question of the college entrance examination math paper!

But just like that, Li Yuanjia just stood quietly, watching quietly, without any impatience or any intention of helping-he knew how difficult it was for a girl who had been in Zhenguan for 12 years to have a simple topic for future junior high school students!

If she can do it herself, the satisfaction is not comparable to that of others.

Fortunately, Li Yuanjia didn't wait too long, but after three or four minutes, Fang Fengzhu finally figured it out, and brushed the list and came up with the final result......

"Smack! Syllable! Syllable! ”

After hearing the applause behind him, Fang Fengzhu was startled, and quickly turned his head to look, and a surprised smile suddenly appeared on his face: "King, you are back...... When did you come back? ”

"Hehe, I've been watching it for a while."

Pointing to the white paper in front of Fang Fengzhu, Li Yuanjia smiled: "I've been watching you finish this question...... Bong-joo, it seems that it won't be long before you can finish these six books. ”

After finishing the study, the progress will be able to catch up with Li Tai.

It's a pity that Li Tai relies on self-study, and Fang Fengzhu accepts at least half an hour's teaching from her husband every day, after all, Li Yuanjia is idle every day, and he is very willing to read with his wife, do problems or something.

"yes, yes."

With a small mouth, Fang Fengzhu's face was also full of happiness.

No matter what era it is, there are many people who don't like to learn, but there are also many people who love to learn, because when you finish a book or solve a problem, the satisfaction is actually not weaker than winning a game game, or even much stronger!

Fang Fengzhu was full of satisfaction and happiness at this time.

And while she was happy, Li Yuanjia pulled her to sit down and chat, said her thoughts little by little, and then looked at her expectantly: "Fengzhu, do you think what I want can be realized?" ”

"This ......"

After hesitating for a moment, Fang Fengzhu smiled bitterly: "King, I think you may really want to be ...... bad"
