Related introduction:

Jiaozi is the earliest paper money in China. One of the names of paper money in Song and Jin Dynasties. In the early years of the Northern Song Dynasty, Sichuan used iron coins, which were light in weight. 1 0,000 coins weigh 25 Jin, and it took 90 Jin to several hundred Jin to buy 1 piece of silk. It is inconvenient to circulate. So, the merchant issued a kind of paper money called Jiaozi instead of iron money.

Ancient coins in China were often named after the year of the emperor, also known as "annual money". The annual money has been customized since the Song Dynasty. In the Song Dynasty, the title changed frequently, and a lot of money was invested in it. After the Yuan Dynasty, all the coins in the past dynasties were basically named after the year number.

Jiaozi first appeared in Sichuan and distributed in Chengdu in the early Northern Song Dynasty (1023). The original jiaozi is actually a certificate of deposit. In the early years of the Northern Song Dynasty, there was a kind of "cross-store" in Chengdu, Sichuan Province, which operated cash custody business for businessmen who were inconvenient to carry huge sums of money.

The depositor delivers the cash to the shopkeeper, and the shopkeeper fills in the deposit amount on the paper roll, and then returns it to the depositor, and charges a certain storage fee. This kind of paper voucher that temporarily fills in the deposit amount is called payment.

With the development of market economy, jiaozi is widely used. Many businessmen jointly set up jiaozi stores that specialize in issuing and exchanging jiaozi, and set up branches in various places. Because the shopkeeper kept his word and picked up the goods at any time, jiaozi gradually won a high reputation.
