When Emperor Kangxi saw that it was this person, he immediately smiled. It turned out that it was Tang Bin who dared to speak out.

Kangxi liked Tang Bin very much, and his love here specifically meant that he appreciated and loved him very much. The 54-year-old old man in front of him, who was thin, dry, with an axe and a knife, was Tang Bin, who was known as the "No. 1 Qing Dynasty" in his later generations. He was also one of the top ten Qing officials in Chinese history, and was truly famous in history, along with Ximen Bao, Di Renjie, Bao Zheng, Hai Rui and others. Tang Bin's life was based on the people, encouraged himself, governed the country and pacified the world with virtue, and was a famous Neo-Confucian minister of the three generations of imperial teachers. His honest and dedicated deeds were endless.

However, Tang Bin's current official position is not very high, he is just a lecturer in the Hanlin Academy, who is from the fifth rank. Kangxi was very busy a few days ago, so he couldn't find a suitable opportunity to get to know him well. Today, Kangxi was going to teach at the Imperial College and needed to prepare more people to take on-site notes. Kangxi greeted Zhang Ying in advance and asked him to find a few helpers from the Hanlin Academy to do things together. Zhang Ying also called "tofu soup" together.

Before Kangxi started the lecture, he listened carefully to the "Ask the Saints" of the two Hanlin scholars. When he realized that the older old man was Tang Bin, the emperor was immediately extremely happy. Oh, he recognized another famous person, and this celebrity was different from others.

Kangxi smiled and said, "Tang Aiqing, what's the matter?"

Tang Bin asked bluntly:

"Your Majesty, the format of this account book is so narrow, how can you write so many words? If you said earlier, this year also uses Western digital methods, such as the first day of January of the Gengshen year, how should you convert it?"

Kangxi answered seriously:

"Your dear, I asked you well. Today is the tenth day of the third month of the Gengshen year of the 19th year of the Kangxi reign. In fact, you can write directly on 19-03-10. If you want to distinguish the years and let me decide, you will add 10 before 19, which will be summarized as 10 March 10, 1019."

OK, this emperor was very generous. In order to save trouble, he left the imperial examination and changed the old calendar to the AD. Fortunately, he was a little restrained and reserved 1,000 years of history for his ancestors.

Tang Bin was silent for a long time, and didn't know what reason to refute the emperor. After all, the emperor himself agreed that for the sake of simple accounting, he could temporarily use simplified number years without adding Chinese characters. Although it seemed to violate the emperor's rules, the emperor didn't mind. And it was just for simple accounting. Tang Bin did not think longer for the time being, and he didn't know that after the emperor changed it arbitrarily, with the spread of "simple bookkeeping", all the minor officials and merchants and ordinary people thought it was very convenient to remember the years in this way, but it turned out to be customized by the people without realizing it.

Tang Bin thought about it and asked another question. Tang Bin was like that baby. He heard Tang Bin say:

"Your Majesty, according to what you said, if the amount is 800 taels of silver, then 800. If it is 8 cents of silver, then 0.8 should be written. However, only in the accounts of the Ministry of Revenue and the Ministry of Internal Affairs, the exchange of silver can be counted in millions. If it is a private market commodity, it is actually a matter of dozens of coins or hundreds of coins. How should these eighty coins be kept?"

As Tang Bin finished speaking, many small officials and clerks nodded and said yes. In fact, they had thought about this question several times before, but they just didn't dare to come forward and ask.

Kangxi was very happy. This problem was actually a headache for the emperor. He had already discovered it when he estimated the value and exchange rate of Qing Dynasty coins two days ago. Logically speaking, coins should be the same as paper money, and it is just an intermediate medium for the exchange of things.

However, in ancient times, it was originally 1 tael of gold = 10 taels of silver = 10,000 copper coins, and the gold-silver ratio was decimal, while the exchange rate between silver and copper coins was 1:1,000 kilograms. However, heavy metals used to make coins themselves are very scarce, so the coins also have corresponding market prices. It is precisely because of the actual value of this metal itself, the exchange rate is extremely unstable.

For example: Sometimes the price of silver rises and the copper price falls, and 1 tael of silver may be exchanged for 1,600 copper coins; and sometimes after the price of silver falls and the price of copper rises, 1 tael of silver may be exchanged for only 800 copper coins. This extremely unstable exchange ratio has brought great difficulty to actual transactions, circulation and accounting. At that time, when the ancients recorded the accounts of silver and money, they often needed to add some corresponding reference prices to the market prices of corresponding references for reference comparison. For example: At that time, a local rice price of 60-meal money was made by a pound of pork, and 20-meal money was made by a pound of pork.

However, in modern times, the exchange rate between all banknotes and coins is stable in decimal, which is easy to convert and convenient to circulation. 1 yuan = 10 jiao = 100 points, and only two digits must be recorded after the decimal point. The standard unit of currency is yuan, and the exchange rate between auxiliary coins is fixed and unchanged. The only way to reflect market changes is to increase or decrease the price of people's biological prices.

Emperor Kangxi replied: "This question is very well raised. In fact, I would like to ask you all here, how can you reduce the exchange rate between coins, and it is best to fix it in decimal. Moreover, the uncertain rise and fall of silver and copper prices also affect the fair and stable circulation of coins. What methods can you do to gradually fix the exchange rate between gold, silver and copper coins?"

After Kangxi asked the question, he instructed everyone:

"Your Highness can discuss with you, front, back, left and right."

After saying that, the emperor found his own exclusive "dragon chaise" and sat down, and began to drink tea to calm his mind.

When many officials and officials heard this, they started to whisper. After all, the exchange of gold, silver, copper and currency values ​​and differences are all issues closely related to everyone's daily lives. Even in the Ministry of War, the minor officials who served in the Ministry of Rites were very interested in this matter, and the atmosphere of the exchange and seminar was quite enthusiastic.

A moment later, Kangxi was actually tired of standing, so he simply sat on the dragon throne and asked with a slight question:

"What are the clever suggestions for all the ministers?"

Finally, a junior official from the Ministry of Works stood up and said:

"I reported to the emperor that I thought that between silver and money, a large copper coin could be added, and the exchange ratio could be reduced accordingly."

Kangxi asked him with a smile:

"According to your intention, should this kind of big copper coins be cast as much as possible?"

The clerk answered:

"Since the copper coins in the present are weighing one qian and four cents, large copper coins can be cast one liang and four cents."

Kangxi laughed and asked him:

"Then so on, the super-large copper coins will probably be cast in 14 taels, and they can't hold them in their purse."

Everyone was amused by the emperor's funnyness, and the minor official of the Ministry of Works sat down awkwardly.
