During the period of Kuomintang rule, there were two monetary reforms: the first time, the dual-purpose system of silver and silver dollars was changed to a single silver dollar system; The second time, it changed from silver dollar system to legal currency system. The reform of legal tender is an important monetary and financial policy implemented by the Kuomintang government, and it is also a foreign exchange standard system established by the Kuomintang government to abandon the silver standard system, which shows its colonial nature. In order to plunder wealth and launch a war against the people, the Kuomintang government often used the means of excessive issuance of paper money to make up for the fiscal deficit, which led to hyperinflation and soaring prices, and accelerated the collapse of the legal tender system.
