Can you use "Kangxi Bao Tong" in Yongzheng period?

In feudal society, only gold and silver were the currencies in circulation in each dynasty. After the establishment of the new dynasty, except for the temporary circulation of metal money such as copper coins in the former dynasty in the early days of the founding of the People's Republic of China, the new dynasty immediately began to cast metal money with the year number of the dynasty, and issued an announcement prohibiting the circulation of metal money in the former dynasty (generally not allowed to be exchanged); As for the copper coins of the current dynasty, the earliest coins can be circulated, but when the throne changes or the year number changes, the copper coins of the New Year number are recast. A small part of last year's copper coins will be saved for some reason (such as burial, burial, etc.). ), and most of them will be reclaimed and recast by the Ministry of Finance in circulation (such as paying taxes, etc.). ), but it will not be abolished.

You asked whether Kangxi copper coins could be used in Yongzheng period, and the answer was yes.

Tell a joke, if you see in any book that Qianlong copper coins were used in Yongzheng period, then this book must be made up!
