1. At first, there was no money, but people only had gold or things. For the convenience of management, the state stipulates that 1g gold is equal to 2 19 yuan (legal tender), and stipulates that people must sell gold to the state. It is illegal for individuals to own gold. In this way, through the national storage of gold, the means of circulating legal tender was realized. This is why the gold standard system died out.

2. As a subject, the state has the right to tax, that is, the right to obtain the fruits of labor from citizens, which is the state finance. Therefore, the money that the country buys goods is not directly printed by it, but the real fruits of labor in the market, which will not cause inflation. This is why many countries emphasize the strict separation of finance and currency, which means that countries cannot issue more money through their own influence.

3. The amount of money in circulation is monitored. When there is too much money in the market, it will be adjusted by monetary policy, such as deposit and loan interest rates, reserve ratio, market separation, etc., which will be done by the central bank.

4. If the currency in circulation in the market is only 50 yuan, but you have 100 yuan, it means that it has been inflated, and the central bank will print more 50 yuan for you.
