He was so careful and cherished when he put it out, it was all a subconscious action, and it couldn't be faked.

"This is what I used before, I originally wanted to give it away or simply throw it away, but I couldn't bear it."

He sighed lowly, his fingers nostalgically brushed the round and smooth abacus beads, and said self-deprecatingly: "I originally thought that I would never have the opportunity to fiddle with these again in my life, and I would never fiddle with these again, but I didn't expect——"

He bent down slightly at Qiao Xiaoru and said softly: "How does Qiao Niangzi want to take the school exam, please!" ”

"Good!" Qiao Xiaoru smiled and said a question of general difficulty in purchasing.

People who have never eaten pork and have seen pigs run, and those who have received higher education in modern society can still come up with a few practical problems about arithmetic.

This was difficult for Tang Liujin, I saw him sitting at the table, his waist straight, his shoulders stretched, and his ten fingers plucked the abacus like a lingyan flying.

But hearing the crisp sound of crackling, soon, Tang Liujin reported a number, wrote it on the paper, and showed it to Qiao Xiaoru.

He wrote Arabic numerals, thanks to the great Emperor Taizu, yes, Arabic numerals were implemented by Emperor Taizu, and now the entire Dahua Dynasty is used up and down, which is very convenient for counting and writing.

Of course, in the Dahua Dynasty, this is not called Arabic numerals, this is called arithmetic counters, which is a symbol invented by Emperor Taizu.

Qiao Xiaoru nodded, and then came up with one, two, and three questions.

The questions are getting more and more complicated, and the difficulty is naturally getting higher and better, and the fat sister looked at Qiao Xiaoru's gaze, and gradually became full of surprise and admiration, as well as disbelief.

It's not that she understands the questions, in fact she doesn't understand them at all. But that doesn't prevent her from listening to more complex questions than the other.

The person who can come up with such a complex topic that she doesn't even understand is definitely not a simple person.

I didn't expect that the little woman who was pleasing to her eyes and saved her son and became sisters had such a great ability!

Her fat sister's gaze is really like a torch.

Tang Liujin can also solve every question, of course, the time spent is longer than the other.

Like Sister Fat, Tang Liujin's gaze gradually changed, and he subconsciously admired from the bottom of his heart: This Qiao lady really has some ability! This ability to settle accounts is not below himself.

For a while, he couldn't help but feel a big blow: he really went back more and more, and the little girl Qiao was no worse than him.

Qiao Xiaoru breathed a sigh of relief, the people introduced by Sister Fat were really reliable.

This Tang Liujin is basically ready to use.

"I'll give you one last question, and if you can answer it, then it's settled." Qiao Xiaoru smiled.

Tang Liujin immediately knew that the main event was coming, and immediately nodded intently: "Qiao Niangzi, please speak." ”

"Do you know persimmons?" Qiao Xiaoru asked.

Tang Liujin was stunned, although he was a little inexplicable, he still nodded: "I know, a kind of preserved fruit made of persimmons." ”

"Well, then you heard clearly," Qiao Xiaoru said: "The total cost is 30,000 taels, and it is necessary to produce persimmons." How to allocate the 30,000 taels to buy or lease land to build persimmon orchards and plant persimmon trees, purchase persimmons on the market, build a workshop for making persimmons, and have various labor costs and capital turnover? How much does each item cost? ”

After hearing this, the fat sister glanced at Qiao Xiaoru and smiled.

Tang Liujin was stunned, and went over this topic again in his heart, Fang smiled bitterly: "This, there is no data for this-"

"Don't worry," Qiao Xiaoru said with a smile: "You can do market research, I can wait a few days to get the answer, but you have to make this question yourself, and you can't find someone to help." ”

"No, don't wait, don't wait a few days," Tang Liujin rubbed his forehead and said, "You let me think about it!" ”

"Okay." Qiao Xiaoru smiled, knowing that this matter could not be explained clearly in a while, and nodded.

Tang Liujin smiled apologetically, got up and went to the courtyard.

Aunt Tang sighed softly, looked outside the door, and then at Qiao Xiaoru, but couldn't help but smile and asked, "Lady Qiao, look-my family is six catties...... Will it succeed or not? ”

Qiao Xiaoru said with a smile: "I don't think there should be any problem, as long as he can answer this question, I will hire him as Mr. Bookkeeper." Even if he can't answer, it doesn't matter, if he is willing to have other suitable work, I can hire him to do it. ”

Sister Fat's eyes lit up, clapping her hands and laughing: "Yes, yes, why didn't I think of this?" Alas, Xiaoru, you are so good! ”

Saying that, he smiled at Aunt Tang again: "Old sister-in-law, you can really put your heart in your stomach now, my sister is a real person who says everything, she wants to do a big business, and it is more when she uses people!" Since she said so, she will definitely arrange six catties. ”

Even if Aunt Tang can't trust Qiao Xiaoru, she can trust Sister Fat. After hearing this, he was also overjoyed, and couldn't help but get up and bow to Qiao Xiaoruyi, and said with a smile: "Qiao Niang, you are really kind-hearted!" No matter what work is done, we will not dislike it with six catties! ”

Where is Qiao Xiaoru willing to accept the gift of such a trembling old man?

was startled and hurriedly got up to avoid it, waved his hand and smiled: "Auntie, please take a seat, let's just sit down and talk!" In fact, I want people to do the work, who will do it? It's not worth it! ”

Aunt Tang sat down twice, and asked her to sit too, with a smile on her face, but sighed in her heart: Having said that, who will do it or not, and how many people are willing to ask her son to do it?

Soon, Tang Liujin came in from outside.

"Yo, think about it so quickly?" The fat sister smiled: "When you went out, your face was very ugly!" ”

Everyone laughed.

Tang Liujin arched his hand at Qiao Xiaoru, said "wait", and sat down at the table to write hard.

Soon, he filled a full sheet of paper, blew the ink on his head, and handed it to Qiao Xiaoru with both hands: "Qiao Niangzi, please take a look." ”

The fat sister also stretched out her head to take a look, and said with a smile: "What kind of account is this, it's all words at first glance." ”

Qiao Xiaoru took it, and Tang Liujin said: "I understand the various cost items that need to be spent one by one, as long as I inquire about the price according to this list, I can calculate a reasonable distribution, Qiao Niangzi look at it - is this okay?" ”

Although Qiao Xiaoru is not very proficient in traditional Chinese characters, he can understand the basic meaning, only to see that from buying land to rent, purchasing persimmons, establishing workshops, making persimmons, selling, etc., all the labor and management involved and various possible sporadic expenses are all neatly classified and clear at a glance.

Indeed, according to this list, the specific cost can be clearly calculated as long as the quotation is requested.
