In the past, it was used most frequently by ordinary people, because the value of copper coins is relatively low, and silver is on top of copper coins, so it is a large bill, just like we usually think that 100 yuan is at least 100 yuan, because the value of silver is relatively high, and ordinary people use it more, such as buying some daily necessities and food, so copper coins may be used. This thing is not large in quantity and of low value, but generally speaking, valuables and wealthy families use silver.
Paper money was introduced in the early Ming Dynasty. These paper money are somewhat similar to our current paper money, but this thing is difficult to handle because of its storage. Although it is easy to put in your pocket, it is easy to break and so on, which is very troublesome. Now our RMB is still relatively strong, because the modern technology we use is definitely different from that of the Ming Dynasty. At that time, it involved anti-counterfeiting problems and was easy to carry when it involved network management. But it is not so easy to completely preserve it, so this problem was discovered in the early stage, and then silver, copper coins and paper money were gradually allowed to be preserved.
These currencies in the Ming Dynasty are similar to those in many other dynasties in history, that is, copper and silver are used, but paper money is really rare, because paper money is more common in the Ming and Qing Dynasties, but like the Tang Dynasty and even previous dynasties, paper money is not often used. It was not until the Song Dynasty that 1 time appeared. Something similar to a paper passbook was called Jiaozi, which was basically nothing before.
