What is history: it is the echo of the past to the future, the reflection of the future on the past. - Hugo
From the unification of China by Qin Shi Huang to the overthrow of xuanun in the Qing Dynasty, China's feudal society has experienced a total of 352 emperors, and among these emperors, there are 146 emperors of the unified dynasty. There are qin emperors and Han Wu who have made great achievements in history, and there are also some emperors who have done nothing, and among these emperors, there is an emperor, which has to be mentioned, that is, Zhu Yuanzhang, the founding emperor of the Ming Dynasty.
Emperor Gao of the Ming Dynasty Zhu Yuanzhang (1328 – June 24, 1398), courtesy name Guorui (国瑞), originally known as Chongba, later named Xingzong, Washu Zhongliren (present-day Fengyang, Anhui), was the founding emperor of the Ming Dynasty.
After Zhu Yuanzhang became emperor, he was intelligent and far-sighted, mighty and heroic, collecting heroes, and pacifying the world, and one of the most important things was to mint new coins. Zhu Yuanzhang decided to adopt the new era name "Hongwu" as the name of money and cast Daming's "Hongwu Tongbao". According to the Ming Shi Food Chronicle, "(Peng Shen and Taizu) ascended the throne and awarded Hongwu Tongbao qian, whose system was five grades: dang ten, dang five, dang three, dang two, dang one."
At the beginning, it was minted in the capital, and later the amount of money needed was very large, and it was simply not enough, Zhu Yuanzhang ordered all provinces in the country to mint money in their own provinces, at this time there was a problem in the bureau, the money minted by the provinces was uneven, and the quality and size were very different. Some officials were corrupt, embezzled, cut corners, and the money minted was small and thin, and because the currency styles were similar, it was not known at all who had cast it, and at this time Zhu Yuanzhang thought of a small method, and he ordered the provinces to write the abbreviation of the province on the back of the money from now on, so that who was corrupt and corrupt at a glance, put an end to corruption.
