Wei, Shu and Wu are called the Three Kingdoms in history. During this period, the monetary system was complicated, wars continued and historical records were unknown. Nowadays, it is difficult to distinguish between the casting place and the casting time when it is broken into the currency of the Three Kingdoms period. During the Three Kingdoms period, the monetary systems in different places were different. Wei won five baht, Shu invested five baht, and there was another 150 baht. Wu has five hundred big springs, one thousand big springs, two thousand big springs, five thousand big springs and so on. In addition, when Taiping Hundred Money and Dingping Hundred Money were returned to the Three Kingdoms, Taiping Hundred Money was cast by Yizhou secretariat, and Dingping Hundred Money may also be cast by Shu.
