1. Before and after the Opium War, there were no foreign banks in China, and metal currencies were always used in China: gold, silver and copper, of which silver and copper can be directly circulated. However, both silver and copper are heavy and inconvenient to carry, so since the Song Dynasty, China began to use paper money, which was called Jiaozi at that time, and there are "money houses" similar to banks in China, which can store and exchange paper money and metal money. Therefore, China circulates paper money and silver and copper coins at the same time, and will not only use silver. The scenes of giving out hundreds of taels or thousands of taels of silver in TV dramas are all fake. 100 taels. However, domestic banks have no contact with domestic banks. Therefore, foreign countries mainly use physical silver to trade with China. Foreign paper money cannot circulate in China. Modern China Bank was founded in 1897 and named as China Commercial Bank.

2. The earliest foreign bank was the Bank of Venice, Italy, which was established in 1580. After the opening of the new sea route, western colonists led by gangsters such as Columbus, Da Gama and Magellan began to invade and "trade" Asia, Africa and Latin America, but at that time, metal currency was still the main currency, and no one would regard colorful "foreign paper" as a substitute for gold and silver. Paper money is generally only used in China. Paper money is just a "bill" of gold and silver, and credit is based on gold and silver in bank inventory.
