Banks are financial institutions engaged in credit intermediary business, such as deposits, loans, wire transfers and savings. Its main business scope includes absorbing public deposits, issuing loans and discounting bills. In China, China People's Bank is the central bank of China, and other banks include China Construction Bank, Agricultural Bank, China Merchants Bank and China Industrial and Commercial Bank.
In the middle ages, there were only two kinds of people in the world who had money, one was a nobleman and the other was a bishop. Therefore, banks are unnecessary because there is no commercial activity at all.
/kloc-in the 0 th and 7 th centuries, some civilians became rich through business and became wealthy businessmen. To be on the safe side, they all put their money in the king's mint. It should be noted here that there was no paper money at that time, and the so-called saving money refers to storing gold. Because the system of "free coinage" was implemented at that time, anyone could take gold bullion to the mint and cast it into gold coins, so the mint allowed customers to store gold.
Although the confiscated gold was finally returned to the original owner, the merchants felt that the mint was no longer safe. So, they put the money with a goldsmith. The goldsmith issued a voucher to the depositor, and then he could take out the gold with this voucher.
