Hearing Wang Xiaolao's tone of Versailles, Wang Yi'an's eyes couldn't help but pass with a hint of shock.

He didn't know Liu Wan's identity and origin, after all, he was a generation behind Liu Wan.

On the contrary, he was more impressed with Wang Dazhi.

Because Wang Dazhi drank alcohol and loved to play drunk, he once held a stick after drinking and drove Wang Xiao and his sons all over the village.

Such a scene made Wang Xiao and his children very unable to hold their heads up among the children in the village when they were children.

It was rare to see Wang Xiao's proud tone and proud expression, which made Wang Yi'an couldn't help but look at Liu Wan with admiration.

He introduced the brush to Liu Wan more enthusiastically, as well as the origin, material, and price of the paper, what is the difference, and how cost-effective.

People are like this, when they know that the other party is a layman, they will recommend products to her more casually, but if they know that the other party is an insider, they will naturally not dare to slack off, but will be more attentive.

Liu Wan compared several kinds, and finally decisively chose the cheapest one.

Because she found that the current pen, ink, paper, and inkstone are too expensive, and if she buys them all, it will cost almost ten taels of silver.

And the paper in it can only be used by my family for a week.

If a person learns to read, the paper is estimated to be enough for a month.

This is enough to explain why there are so few children from poor families studying now, and the cost of learning is huge, no matter which dynasty the investment in education is a huge amount of money.

There are comparisons and discoveries, Liu Wan thought to herself: It is difficult to produce a noble son from a poor family, and it is not a phenomenon only in modern society.

In any dynasty, it is not easy to change the fate through knowledge, and it requires the determination and courage of the whole family to support learning.

In contrast, in modern society, learning is much more convenient and cheaper, ubiquitous network information, online tutorials are varied, you have to study hard, and you can still do great things with less money.

Liu Wan carefully selected, and finally chose the cheapest stationery, which made Wang Yi'an, who was carefully recommended, cry and laugh.

However, when he saw Liu Wan's calm appearance, he felt that Aunt Liu was not the same as before, and she exuded a confident temperament inside and out.

Wang Yi'an couldn't help but sigh, could it be that Wang Dazhi's death was a relief for Aunt Liu?

When a woman leaves a man, it doesn't seem that she will live a bad life, and Aunt Liu in front of her is an example.

Wang Yi'an led Liu Wan and them to settle the bill with the owner of the store.

Boss Zhuang and Wang Yi'an are quite familiar, because there are only so many scholars here, and these people come and go, so of course they will be familiar.

Boss Zhuang greeted him politely and said, "Yi'an, who is this bringing to school?" Coming to buy new stationery again? ”

"Hehe, Boss Zhuang, this is Aunt Liu of the same clan, how many children in her family want to be literate, do you think it can be cheaper? She will come back to your business more often in the future. ”

Boss Zhuang saw that Liu Wan bought a lot of money, so he agreed:

"I'll do the math first and see how much it costs."

After speaking, Boss Zhuang used the calculation chip to count, and it seems that he usually calculates it like this.

Seeing that he was calculating so hard, Liu Wan used the mental arithmetic learned by the Children's Palace on the side, silently calculated it, and said:

"Boss Zhuang, 7.2 taels of silver."

"Yo, how did you calculate so fast?" Boss Zhuang looked at Liu Wan suspiciously, not believing it at all, and said, "I have to work hard to count with a calculation chip, and I haven't watched you count, don't count randomly, right?" ”

Originally, Boss Zhuang had a kind vision, but when Liu Wan interrupted her, and saw that she was dressed as a peasant woman, he couldn't help but feel a little annoyed.

I guess I was thinking in my heart, you, a country woman who can't read big words, will really make trouble.

Liu Wan saw that Boss Zhuang didn't believe her, so she had no choice but to stand on the side and wait.

Wang Xiao saw that his mother was reprimanded, looked at Wang Yi'an on the side, and saw that he was expressionless, but Wang Xiao felt a little unbearable in his heart.

The mother finally established a better image because of her literacy, but now she is robbed by the bookstore owner, and the image of the mother must be ruined.

Wang Yi'an didn't show ridicule, that is, after people went to the city to learn etiquette, they knew how to treat people with courtesy, but they definitely didn't think so in their hearts.

Wang Xiao was a little secretly uncomfortable.

What it was like, he couldn't tell.

All in all, I just don't want my mother to be looked down upon by outsiders!

As a result, Boss Zhuang slapped his thigh:

"Hey, that's right, 7.2 taels!"

Liu Wan smiled and didn't speak.

Well, just praise me!

"This lady, you guessed, right? That's right! ”

The boss of the village said authentically.

"Oh, I'm not guessing, I'm using mental arithmetic."

Liu Wan said lightly, it didn't seem to be a big deal.

In modern society, mental arithmetic is certainly not a great thing, and there are a lot of free tutorials on the Internet.

But Liu Wan knew that the opportunity had come!

In ancient times, mental arithmetic was certainly a big deal!

"What's the method of mental arithmetic?"

The bookstore owner was intrigued when he heard this.

Seeing the boss's curious look, Liu Wan knew that the method of mental arithmetic had not yet appeared in this dynasty.

Mental arithmetic is very useful for shops that usually do small business, and it can greatly improve work efficiency.

If the boss learns the method of mental arithmetic, there will be no long queue for payment.

"This is a set of algorithm know-how that my mother's family has accumulated for generations, and it is not easy to pass it on, if you want to learn, twenty taels of silver tuition, I will cover the church!"

Liu Wan said generously.

Boss Zhuang was a little confused when he heard it, he went in and out of business every day, and he had a lot of accounts to calculate, and he was dizzy every time, if he could learn the mental arithmetic method that Liu Wan said, he could save a lot of mental effort, in fact, it was also very useful.

But twenty taels of silver is too expensive.

Boss Zhuang shook his head and said, "Is fifteen taels of silver okay?" ”

Liu Wan didn't care about selling her skills, mainly because her source was relatively cheap, simple mathematical applications like mental arithmetic, and in order to improve her mental agility and logical ability, the flowers of the motherland learned it early in the Children's Palace.

"The method of mental arithmetic is worth this price." Liu Wan refused to make a counteroffer.

Boss Zhuang hesitated for a moment and said:

"But I don't know if your mental arithmetic method is really practical, if it is practical, twenty taels of silver can be traded."

"Okay then, why don't you stand by and see how I settle the score."

After Liu Wan finished speaking, several students came to settle the bill with the stationery they had bought.

So Boss Zhuang stood on the side and watched Liu Wan settle the bill.

Liu Wan glanced at the stationery and books bought by the checkout person, and quickly quoted the total account according to the single price quoted by the boss.

Boss Zhuang checked again, and the score was exactly the same, more than twice as fast as his usual time to settle accounts.

Boss Zhuang personally experienced Liu Wan's efficiency in settling accounts, and was convinced, saying:

"Okay, then I'll give you twenty taels of silver, and you'll teach me."
