Compete for the Song Dynasty

At this time, the study is very quiet, even if a needle falls on the ground, you can hear it clearly. Cui Deyou is looking nervously at Wang, and then at Jia Xian, who is holding his breath and is about to speak. He works in a bank and knows that he has great responsibilities. There are so many silver coins, but if there is a mistake, I can’t explain it to Wang Pang, and Jia Xian, a kid who has only been working in the bank for a few days, is quite popular, but this matter of giving Wang Pang’s opinion, let alone Jia Xian, is the whole palace. There is no precedent. This is not to say how strict Wang Pang is, but in everyone's opinion, there is no problem that Wang Pang can't solve. There is nothing he can't do.

Wang Pang quietly looked at Jia Xian, a young man in his early twenties, who is still inconspicuous, but who knows that this young man is the author of books such as "The Yellow Emperor's Nine Chapters of Algorithm and Fine Grass", "Release Lock Calculation Book" and so on. The creation of the "Jiaxian Triangle" and the "Increasing Multiplication and Opening Method" is more than 700 years earlier than the European mathematician Horner's method

Jia Xian closed his eyes to calm himself down, then bowed his hands to the king and said, "My lord understands that your bank's profit is based on the interest rate difference between the loan and the deposit. I always feel that the interest rate difference cannot be [-]%. Let’s say that the world is peaceful and the grains are plentiful. The people have enough money to put it in the bank, which is safe and has interest. But if there is a famine and food prices rise, the money in the hands of the people is not enough to subsidize the rising part. Would you put your money in the bank?"

Jiao Deyou curled his lips when he heard this: "You say this sounds right, but it's all a famine, let alone the common people, even if they don't have any money in the bank, it may not be enough to buy food. What does this have to do with interest? "

Wang Pang waved his hand: "Brother Jiao, let him go on first." Although Wang Pang goes in and out on weekdays and everyone respectfully calls him the prince, but in private, Wang Pang still treats the people around him as brothers.

Hearing what Wang Pang said, Jia Xian didn't envy him and looked at Jiao Deyou who could call the prince a brother. This is called Shopkeeper Jiao, but he felt more confident when he saw Wang Pang let him continue talking. He looked at Wang Pang and saw that Wang Pang nodded lightly, and he seemed to be more encouraged, "Shopkeeper Jiao, you are right, when there is a food shortage, the common people can't buy food and the food is mostly hoarded by big households. Why do they hoard it? Because hoarding food can make enough money, but although the prince opened the bank to face the common people, what really makes the bank profitable is the money of the rich gentry. Let’s put it this way, the price of rice in Qingli years was only seventy or eighty yuan a bucket In the second year of Huangyou, the price of rice was 120 coins a bucket. If I had [-] coins, I could have bought a bucket of rice. If I put it in the bank for a few years, I can’t even buy a bucket of rice, so what should I do with the bank?"

"Well, that's good to continue." Wang Pang listened to what the young man said was good. After all, he came back to the Song Dynasty from modern times. little is known

"No, if you buy a bucket of rice and leave it for six years without eating it, it will be destroyed by worms." Jiao Deyou didn't intend to pick on Jia Xian's faults, but he didn't want Jia Xian to give Wang Pang any opinions.

Jia Xian is no longer as nervous as he was when he first came in. He nodded and said, "I'm just giving an example. In the second year of Huangyou, the price of rice increased from 120 Wen a dou to 180 Wen a dou in one year, and then it rose to 120. Wen Yidou Many merchants and wealthy households are scrambling to buy goods day and night because of the profits here. If I have [-] Wen at the beginning of the year and buy a bucket of rice at the end of the year, I can earn [-] Wen. But if I put it in the bank, I can only get more than three Wen. There is such a huge disparity in interest rates here, how can these wealthy households deposit their money in the bank? The rice from shopkeeper Jiao won’t rot for a year, right?”

Wang Pang knew in his heart that although what Jia Xian said was only a special case, and he was only at the stage of feeling that Wang had not advanced to a theoretical basis, he had already thought of using bank interest to regulate the market economy. Jia Xian is indeed a talent.

Jiao Deyou scratched his head, looked at Wang Pang and smiled half-understanding: "Jia Xian is right, but Jia Xian, do you have any solution?"

At this time, Jia Xian lowered his head: "My lord, I just thought of this problem but haven't figured out a solution yet."

"Hey, you kid, I thought you'd thought it all out." Jiao Deyou would have to give Jia Xian another chance if he didn't sit there far away.

Jia Xian said with a full face of grievance: "This is not to say that it can be solved, and I don't know whether the grain will rise or fall this year."

"You don't know whether the grain is rising or falling, and you don't know the magnitude of the fluctuation, right?" Wang Pang asked calmly.

"Hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm" Jia Xian stared wide-eyed and kept nodding

"Hahaha" Wang Pang laughed heartily. Seeing Wang Pang laughing, Jiao Deyou and Jia Xian laughed too. Jiao Deyou was happy to see Wang Pang happy, while Jia Xian laughed a little awkwardly, and was infected by Wang Pang's smile.

"Well then, who is the guarantor for you to come to Yongzhou to work in the bank?" Wang Pang became more and more interested in Jia Xian. He put his arms on the table and looked very relaxed. Although Jia Xian couldn't think of a way for a while, Wang Pang thought already have an idea

"It's Mr. Qian Yi." Jia Xian replied honestly: "Mr. Qian and my mentor Chu Yan are close friends, so when I came, I went to Mr. Qian and asked him to guarantee me."

Hearing that it was King Qian Yi, he remembered that the people in the palace were poisoned. It was Qian Yi who came to prescribe medicine for everyone. You don’t have to go to the bank.”

Before Wang finished speaking, Jiao Deyou hurriedly said: "My lord, Jia Xian, is a bit reckless, but he has a good eye for things..."

Jia Xian thought about it, it seems that the prince doesn't like his suggestion. When the shopkeeper Jiao reminded himself to be more cautious, he was too proud just now. Maybe he didn't make the prince unhappy. He gave Jiao Deyou a grateful glance. Although the shopkeeper is rough and rough Pulled but kind hearted

"Haha Brother Jiao, you appreciate this kid so much, don't you mind if I take personal use from you?" Wang Pang laughed

Jiao Deyou was taken aback for a moment, then he understood, and hurriedly called Jia Xian: "Stinky boy, you are really lucky, why don't you hurry up and thank the lord"

Jia Xian didn't realize it all of a sudden, he stayed there, he was secretly wondering when Wang saw him with a dazed look, thinking that this young man is not bad, but he has no experience of the world, just like a blank piece of paper, he will definitely make a difference in the future if he cultivates well, "Jia Xian, I How do you feel about keeping you by my side to do things?"

Jia Xian opened his mouth: "Oh, okay, but I can only count. I don't know what the prince left me by your side. I don't know if I can do it."

Ordinary people would not be so happy. Jia Xian is quite honest. Wang Pang believes that he has read the right person: "I want to accept a student, are you willing?" But when it comes to the specific calculation details, I may not be as good as this Jia Xian, especially in the future, not only will the interest rate fluctuate, but also the exchange rate with Korea and various foreign countries. All these must be carefully calculated.

Even though Li Eun-hee is a good talent that I cultivated by myself, she is a woman after all, and she is also from Korea. What's more, Li Eun-hee's husband is Wan Yan and Li Bo. The days to come are still long. Wang Bang must cultivate a few more talents for himself assistant

Students following the teacher is not the current teacher-student relationship. In ancient times, the master had to respect the students who could be princes like serving their fathers. Who wouldn’t want that? What’s more, who would disagree with this little prince’s character, talent and learning? Jia Xian, who was working by the prince's side, suddenly understood in a trance. He knelt down and kowtowed with a plop: "Master is here to be worshiped by the students."

"Hehe, get up quickly." Wang Pang waved his hand: "You go back and tidy up and come to the palace to report tomorrow, first stay with me for a few days, and I will arrange for you to do things."

"Thank you, my lord. Thank you, Master." Jia Xianle couldn't even close his mouth. He didn't know that Wang Pang was also secretly laughing. In the future, when Jia Xian was mentioned in history books and mathematics textbooks, he should not only write that he was a student of Chu Yan. It is a good opportunity to leave a name for yourself through the ages

Jiao Deyou looked at him and was also happy. This brother is very informal in doing things. A prince actually accepted a bank clerk as a student. After laughing, he said to Jia Xian: "You go back first, I have something to talk to the prince, and remember to discuss it privately later Here, you can ask Master to go outside, or you have to respectfully call yourself the prince, and you are not allowed to use the banner of the prince when you do things, or I, Uncle Jiao, will not be able to spare you first."

Jia Xian smiled and said "yes" to Wang Pang and Jiao Deyou. He turned and walked out of the study. He couldn't hold back his joy and almost ran out all the way. He had just walked to the moon gate at the corner of the corridor in the other courtyard of the study, and bumped into Cai Jing head-on.

Cai Jing didn't just trot this time, he almost ran all the way back: "Oh, brat, you don't look at the road!"

Jia Xian looked up and saw that it was Cai Jing who recognized the young man next to Wang during the day. I don't know if this is also a student of the prince. That is his senior brother. He greeted with a smile on his face: "Senior brother, you are here."

Cai Jing was full of impatience: "Brother, get out of the way!" Jia Xian, who was about to salute, hurried to the study

Jia Xian shook his head and thought to himself that this man is so strange that the prince is so nice, why is he so old and fierce? He didn't know that Cai Jing was in a hurry at the moment. He ran to the door of the study next to the king and said out of breath: "The prince is not good." something big is going to happen"
