Counterfeit money has been circulating for a long time.
Actually, counterfeiting has a long history. No matter what gangsters in the Jianghu or emperors with high status, they all have a black history of counterfeiting. As far as counterfeiting technology is concerned, the means of pouring lead or iron into rivers and lakes are pediatrics and belong to Jianghu people. Real counterfeiting technology is better than official counterfeiting.
Liu Bei lived in exile for the first half of his life, making a living by doing small business, and he didn't save any money in middle age. It was not until Guan Yu and Zhang Fei became brothers of the opposite sex that they began to raise flags for revolution, and the army did so. Where does the military expenditure come from? At first, I was grateful for Liu Bei's support, but as time passed, it was no good.
In fact, as early as the Western Han Dynasty, someone was already making counterfeit money.
Before Liu Bei and Sun Quan made counterfeit money, someone had given them a good start. This man is Wang Mang of the Western Han Dynasty. In order to cope with the domestic economic crisis, Wang Mang decided to cast counterfeit money into new coins, changing one for fifty, which increased the economic aggregate of the Western Han Dynasty by fifty times at once, but also laid a curse for Wang Mang's downfall.
