I saw Li Min’s actions and heard Li Min’s explanation.
Di Renjie and Wang Xiaotong first looked shocked, then suddenly realized, and finally became ashamed.
It turns out that this problem is so simple.
As long as you change your thinking, you can easily answer it.
It's ridiculous for both of us that after thinking about it all night and most of the day, we couldn't come up with the correct solution to the problem.
It seems that the gap between them and His Highness is really far, far away.
Seeing the expressions on the two people's faces, Li Min smiled slightly and said: "Actually, your idea is not wrong. This is to calculate the volume of the water ladle. Of course, it can be calculated in this way, and the water ladle can be filled with water.
Pour into other containers to convert."
"But what if what you want to measure is the volume of a reservoir or a pond? Then there is no way to convert it. And the methods you two think of have merit. When you have nothing to do, you can try it
method, see how big the error will be using your method and the actual quantity, and how to reduce this error."
After hearing Li Min's words, Di Renjie and Wang Xiaotong couldn't help but look thoughtful again on their faces.
…
In the afternoon, Li Min came to Chang'an City.
In Chang'an City, there is also his palace of Shu Prince.
However, there are only some servants left inside to clean the room and guard the door.
Now that the princess has followed him to Yizhou, Li Min is not in a hurry to go back.
Then, Li Min went directly to the palace, and first went to Hanxiang Hall to visit his mother-in-law, Concubine Yang.
After arriving at the Hanxiang Hall, Li Min rewarded the palace ladies and warriors as usual, making them all very happy.
"Your Highness, the Third Highness is here and is in the house!"
Oh? It turns out that third brother Li Ke is here?
Li Min hurriedly walked into the room. This time, mother and son were reunited, and they talked about themselves together, so there was no need to mention them more.
However, Li Min found that after his third brother arrived, he seemed not to be well received by his mother and concubine.
Um, okay, don't look at it. Li Min was originally in Yizhou, which was thousands of miles away from Chang'an.
But I can’t stand it now that the two places are connected by train.
And when nothing happens, Li Min can take the train back to Chang'an.
Concubine Yang also visited Yizhou City this year.
Speaking of which, mother and son have met several times this year.
And Li Ke can only come back once a year.
From this perspective, the mother-in-law naturally felt more apologetic after seeing the third brother.
…
The two met with Emperor Tang Li Shimin, and then Li Shimin asked Li Ke carefully.
Li Min was basically ignored.
Well, Li Shimin himself had been to Yizhou many times, so he knew very well about it, and he didn't bother to ask Li Min again.
After Li Ke reported the fiefdom matters, the two brothers said goodbye and left, but Li Min was left behind by Li Shimin.
After Li Ke left, Li Shimin glanced at Li Min and asked, "Come on, don't you have something to report to your father?"
Um?
Hearing Li Shimin's words, Li Min couldn't help but be a little dumbfounded.
Is your father so powerful?
Before I said anything, he guessed that he had something to report to him?
Li Min blinked his eyes, and then asked: "Father, please guess again, what do I want to report to my father?"
Li Shimin was amused by Li Min's laziness and couldn't help scolding him: "Don't be so playful with me. If you have something to say, just say it, and if you have something to say, just fart."
Li Min smiled and said: "Father, it's like this. I want to set up a bank in Yizhou, so I came to ask my father for instructions first. After the bank is established, it will play an important role in the economic development of the Tang Dynasty.
Estimating helps.”
Um?
Hearing Li Min's words, Li Shimin's eyes couldn't help but light up.
It's absolutely incredible that Min'er can admire something so highly!
Thinking of this, Li Shimin couldn't help but ask: "Yin'er, tell me, what exactly is this bank and what is its role?"
Upon hearing Li Shimin's inquiry, Li Min immediately described the role of the bank.
Then, he submitted the bank procedures he listed to Li Shimin.
After listening to Li Min's description of the bank, Li Shimin couldn't help but look thoughtful on his face.
As a wise emperor, Li Shimin had long realized the inconvenience of using copper coins as the main currency.
First, once a large-scale transaction is carried out, the amount of copper coins required is too huge.
It is not convenient to carry or count.
Second, the amount of copper mined each year is extremely limited, and copper coins are becoming increasingly scarce.
Once the quantity of currency is seriously insufficient, it will bring very dire consequences, and even the entire economic system will collapse.
The emergence of banks and the printing of banknotes can solve these two problems very well.
Li Shimin immediately opened Li Min's terms and conditions and read them carefully.
At this glance, it was only half an hour.
Sitting on the sofa, Li Min was so bored that he started to yawn.
Over there, Li Shimin finally digested all the information.
I also have enough understanding of banks.
Li Shimin couldn't help but ask: "Hey, I think it is right for the imperial court to open this bank. The name is Datang Bank. What do you think?"
Huo!
Are you trying to cut off your beard?
Hearing Li Shimin's words, Li Min couldn't help but feel dumbfounded.
Are you saying this so naturally? Don't you feel ashamed at all?
However, Li Min also had to admit that it would be more justifiable if it were opened by the imperial court.
It is even possible to directly replace copper coins with banknotes.
But there is one thing: with the current imperial court, it is simply impossible to open one.
Li Min smiled slightly and asked: "But Father, does the court have enough money to pay? Once there is a gap in funds and the customer cannot exchange the receipt for cash, then the court will no longer have credibility. And this paper currency
, I’m afraid it will really become useless paper.”
Li Shimin, who was originally beaming with joy, couldn't help but start thinking again after hearing Li Min's words.
After a while, Li Shimin had to admit that what Li Min said was indeed very reasonable.
Is the imperial court rich? Of course it is.
But there are many places where the court spends money.
Once there is a disaster year and the court does not have enough storage and cannot exchange cash, something big will really happen.
From this point of view, it is really appropriate for Li Min to handle it.
Li Shimin had no doubts about Li Min's ability to make money.
The emergence of banks can be said to be the best way to solve the difficulties faced by Datang.
But Li Shimin was pondering and did not agree for a long time.
Li Min soon understood what Li Shimin was afraid of.
He is now the governor of the entire Jiannan Road, with territory and troops in his hands.
If there is another bank now, the chips in hand will really be too much, and it will already threaten Li Shimin's throne.
