Money is made by the state, and the state has a special mint, which is hidden and will not be known to the outside world. . . China's central bank is in charge of money. . . However, making money does not mean that the country is not short of money. How much money the country earns is related to many aspects. First of all, ancient coins need gold, silver and copper as raw materials, and their circulation is limited to a certain extent. Secondly, after the emergence of paper money in the Song Dynasty, there was no limit to the cost. However, the decisive factor of a country's currency circulation in ancient and modern times was economy. If there is no money to build it, it will lead to economic imbalance, inflation and soaring prices. If inflation is serious, now 10 yuan can have a meal, and then100000 yuan can only buy one steamed bread. Once the economy is unbalanced, the national system will collapse and the country will perish. Therefore, even if the country is short of money again, it will not risk the country's demise to print money. Instead, we should adjust national and economic policies, promote economic development, increase national tax revenue and income in all aspects, and the country will gradually become rich.
