The high school history teacher will give you the answer:

The emperor of the Han Dynasty adopted "letting the people mint money" and "making laws and prohibiting prohibitions". The former was actually to artificially create domestic inflation, while the latter They used the high prices within the territory of the Han Dynasty to attract merchants to trade. The two were internal and external to each other, and used the "half two coins" enforced by Qin Shihuang as a weapon of economic warfare.

Later, because merchants hoarded and manipulated prices, punitive measures were taken. "The world was at peace, so Emperor Gaozu ordered the people of Jia not to wear clothes or ride in carriages, and imposed heavy rents and taxes to humiliate them."

< p>To put it crudely, after winning the world, Liu Bang fell out, humiliated merchants by means of social status, and "trapped" merchants with heavy taxes, that is, "harvesting wool", but there was no prohibition on "people making money".

Because he had a better way, which is what "Hanshu·Gaodi Ji" says:

(Gaodi 4th year, 203 BC) In August, the beginning of the year is calculation Endowment.

The tax calculation is a poll tax. The explanation of "Han Yi Notes" is:

From the fifteenth to the fifty-sixth year of the Republic of China, the tax is paid, and the people are counted as one hundred and twenty. To control the library, soldiers, chariots and horses.

In the fourth year of Emperor Gao of the Han Dynasty, the Chu-Han War was coming to an end. People between the ages of 15 and 56 had to pay 120 yuan each as a tax. This was a head tax, a very large amount of monetary income, which was used to purchase things. Weapons and equipment, how much can we charge for a population of millions or tens of millions? You can calculate this for yourself. Can you get 1 billion?

Also, minting coins requires manpower, technology and a large amount of metal raw materials. In ancient times, one penny was minted, which consumed the same resources as one penny or even one penny. Not having deflation is already good.
