Why did paper money become the reason why the Yuan Dynasty destroyed the country? What are the advantages and disadvantages of paper money?

In the late Yuan Dynasty, due to the decline of rulers and ruling groups, the system related to paper money has been gradually destroyed. At that time, in order to get more benefits from it, officials of the Yuan Dynasty chose to use their power to make money by themselves. This led to a large number of counterfeit banknotes in the society at that time, and also caused huge economic losses to the people. Due to the unified use of paper money, all regions of the country can conduct transactions fairly. It can also further integrate various ethnic groups and regions, which is of great significance to the stability and development of the country, and at the same time, it can make the rule of those rulers in the Yuan Dynasty more stable. However, by the late Yuan Dynasty, paper money had become the main reason for the decline of the Yuan Dynasty. By the end of the Yuan Dynasty, in fact, the whole government of the Yuan Dynasty had gradually declined. At this time, the relevant banknote system was destroyed under the command of the leaders of the Yuan Dynasty. Paper money has long been unable to play its normal role. At that time, officials of the Yuan Dynasty began to use their power to secretly forge paper money for personal gain. Although this method is beneficial to these officials, it seriously harms the interests of ordinary people. At that time, the rulers of the Yuan Dynasty were very fatuous and could not see the real development of this society at all. Therefore, in the process of printing paper money, it can not meet the needs of society at all, nor can it better adapt to the social situation at that time. Because of the overprinting of paper money, it leads to the oversupply of paper money and the inflation of the whole country. At that time, people could not buy goods normally because the price rose too fast. At that time, it can be said that the people of the Ming Dynasty could not even afford those necessities, so naturally this printing system also caused strong dissatisfaction among the people. If the daily needs of the people are not met, the whole society of the Yuan Dynasty will begin to become turbulent. It can be found that, in fact, the implementation of the paper money system without a scientific management will also lead to the country's demise.
