At this time, China was under the rule of Renzong in the Northern Song Dynasty, but it was the Queen Mother Liu E who was really in charge of political affairs. The world's earliest paper money was born in China, called? Sex? Its birth opportunity lies in the rapid economic development in the Song Dynasty. With the rapid development of economy, the frequency of currency use naturally increases. But before paper money appeared, in the Song Dynasty, the main currencies used in the market were copper coins, iron coins and silver. One disadvantage of these currencies is that they are not easy to carry. For example, at that time, a thousand yuan weighed about 25 kilograms, so a 20 thousand yuan Luo needed to carry 100 kilograms of copper coins to buy it.

In this case, businessmen in Chengdu, Sichuan spontaneously printed a kind of? Paper money? , which is jiaozi. The jiaozi spontaneously printed by Chengdu businessmen appeared in 1008. However, at this time, the payment is not paper money, because its amount is not fixed, but is filled in according to the amount of money deposited by the merchant. What's the name of the place where merchants keep coins? Jiaozi store? . After they deposit the money in the store, the store will give them a token with the amount written on it as a deposit certificate. After the appearance of jiaozi, it quickly spread in Sichuan because of its convenience, and the number of jiaozi stores increased day by day.

However, with the increase of jiaozi shops, there are loopholes in their management, and some shops arbitrarily distribute jiaozi and misappropriate coins. By 1023, the imperial court began to formally take over the distribution and management of private partners in the case of poor development. At that time, in order to carry out effective and standardized management of Jiaozi, the imperial court also set up a special office in Sichuan? Yizhou jiaozi service? . After the establishment of this institution, the issuance of Jiaozi was officially transferred to the imperial court. Also in this year, the court issued the first batch? Official communication? Officially put into use. The earliest paper money in the world appeared according to the issuing time of these official paper money.

Before the official slot was released, its usage was very similar to that printed by the merchants themselves earlier, and the amount above was temporarily filled in. However, on this basis, the imperial court stamped the national seal above Jiaozi. In addition, the imperial court also graded these officials according to the amount of one to ten. When it reached 1039, Song Renzong officially ordered the official donation to be unified into five passes and ten passes. Besides, official friends meet every two to three years? Change? And every time it expires, the old jiaozi needs to be replaced by a new jiaozi before it can continue to be used.
