Since then, Li You has also begun to go to work in the early dynasty and Shangshu Province every day, and has become a member of the Datang office workers.

He is so busy, not only has to deal with a lot of complicated things every day, but also receives a large number of people, even when he returns to the house, he doesn't sleep before 12 o'clock every day, which is used to write all kinds of scientific and technological materials.

There is no way, there are too many things for him to do.

In order to find psychological balance, in addition to enjoying high-quality food every day, he also needs to psychologically comfort himself. He wrote on his bedside: "Being busy is also a kind of happiness, most people want to be busy and have nothing to do, people should be content and grateful." ”

Not to mention, seeing this when he got up every day, Li You's mood suddenly improved a lot.

On this day, Li You was writing an article, and suddenly he was a little irritable, he was stunned for a while, and continued to write, and after writing, he transcribed another copy.

He picked up the two articles and said with a smile: "This is long overdue. ”

Early Dynasty, Taiji Palace.

Li You said: "Father, the Chongyang Festival is approaching, and Erchen recently wrote a poem, I want to ask my father and all the adults to correct it. ”

If someone else comes to promote their poems in the court, they will definitely be questioned, but everyone knows that this is one of Li You's routines, and it is a precursor to proposing a new thing.

Li Shimin said with great interest, "Come and listen." ”

Li You said: "Father, the son should present it to you and all the adults." As he spoke, he took out a stack of letterheads from the briefcase he was carrying with him and presented them to Li Shimin first. Then he asked the eunuch on duty to distribute it to each of the adults.

Li Shimin took a look at it, and the first thing that attracted him was not the content of the poem, but the form of writing.

The first half of the paper reads: "Jiuyue ascends:

Jiu Yue Jiu looked at the township on the other day, and he sat in his hometown.

The people have already left the south in the middle of the country, and the wild goose has come from the north. ”

The second half of the paper reads: "Ascend on September 9th:

On September 9, he looked at the hometown platform, and he sent off a cup in another country.

People are tired of suffering in the south, and Hong Yanna comes from the north. ”

Li Shimin first recited the poem and asked, "Li You, what's going on with the text behind?" ”

Li You said: "Father. Ladies and gentlemen, the first half of the paper is the text that we Datang is using now. The text is very beautiful, but there are too many strokes, too cumbersome, and it is not convenient to write.

The font of the following poem is called a simplified character, I don't know what everyone thinks? ”

The simplified words in front of me don't seem to be much less aesthetically pleasing, and they look much simpler. Since Li You popularized Arabic numerals, people have been very convenient to use, and everyone has no aversion to this simplified font.

After everyone discussed for a while, Xiao Qian said: "Your Majesty, the minister thinks it is feasible, with this simplified font, it is much easier to write and remember." It has the role of a horizontal knife for the popularization of cultural knowledge. "For his son-in-law, the old man must support him.

"Your Majesty, this simplified word is good, it is much easier to write. The minister agreed. Cheng Yanjin said.

"Your Excellency approves."

"Your Excellency approves." Ministers expressed their support.

In the past, Li You solved too many problems for the imperial court, and his prestige was extremely high.

After Li You went to court, people found that all the problems that could not be solved by various ministries were finally handed over to Li You, and they were basically able to give good suggestions. Therefore, there is basically no objection to Li You's proposal.

Over time, many ministers developed a habit and began to rely on Li Youlai.

Li You said: "Father and son suggested that not only should we not only promote simplified characters, but also carry out basic cultural popularization throughout the Tang Dynasty, and run literacy classes in all towns and villages. ”

He told the group about the organization of literacy classes. In the end, this proposal was also passed through the court.

Li You continued to use the knowledge in the science and technology library to bring changes to Datang, and this little change slowly began to play a role, speeding up the speed of Datang's move towards a more civilized and prosperous city.

Banks are called banks because when banks arose, they adopted the silver standard. The silver of the Tang Dynasty was not in circulation, so Li Shimin gave it the name "Qianzhuang".

Li Shimin was very satisfied with the opening of the bank, not to mention the other roles of the bank, and a large number of jobs were added.

On the day of the opening of the bank, Li Shimin personally went to the bank to deposit the first deposit of Datang, and he promised on the spot that most of the money in the palace would be deposited in the bank. Li Chengqian, Li You and others also followed to deposit money in the bank. With their leading role, the court magnates and civil and military officials all rushed to dig out their family's money and deposit it in the bank. After a period of operation, users feel convenient and welcomed by Chang'an merchants and ordinary people.

Then, the household department began to open branches in Luoyang, Yangzhou, Jinyang and other places.

On this day, Jingzhao Yin Chuheng said in the morning court: "Your Majesty, Chang'an County discovered and destroyed a den of minting coins without permission, and arrested 19 criminals. In the Chang'an area alone, from last year to this year, this is already the fourth incident of minting coins without permission.

Some of the dens of privately minted coins are hidden in the dense forests and mountains, in the homes of large families in towns and cities, or hidden underground, which are extremely difficult to find, so they are repeatedly banned. ”

Gao Jingming said: "Your Majesty, the Chang'an region is at the foot of the Son of Heaven, and the phenomenon of private coinage is difficult to stop, and it is even more unimaginable in other regions. Across the country, this phenomenon can be described as rampant. ”

For this kind of thing, no one has been able to solve it for thousands of years, and Li Shimin doesn't ask others. He knew that it would be in vain to ask. So, he asked directly: "Li You, what solution do you have?" ”

Li You said: "Father, the reason why this problem is difficult to solve is not only driven by interests, but also technical reasons. If the coins minted by the household and the coins minted by the people are just minted, it is easy to see the difference between them when they are compared together.

However, after a period of use, wear and tear or rust occurs, and the difference between them becomes difficult to discern.

In order to solve this problem, we must first cut off the benefits brought by the coin itself, that is, the problem of copper content, without copper, it will reduce the attractiveness of private coins.

Second, the problem is solved by adopting new coin minting techniques that make it impossible for criminals to forge them. ”

Li Shimin asked: "Have these problems been solved?" ”

Li You said: "It has basically been solved, and some technical adjustments need to be made. At the end of the year, Chen Ping, who can come up with new coins, can guarantee that the new coins will not only prevent the private minting of coins, but will also be very convenient in use. Here, I ask for your forgiveness for the time being. ”
