Shen Zhou, a modern investment bank executive, was reborn as a death row prisoner in the Hongwu Year of the Ming Dynasty. Three days later, when I asked Zhan, Jin Yiwei asked him if he had anything else to say. He said: Yanyin can be used for futures. A month later, Yangzhou salt merchants lined up to give him money. A year later, the Minister of Household Affairs came to ask for advice on what "national debt" was. Zhu Yuanzhang summoned him into the palace overnight: How about you becoming the Minister of the Ministry of Household Affairs? Shen Zhou smiled: Your Majesty, my backstage is the entire modern finance. Use futures to revitalize salt, use national bonds to fill the national treasury, and use bank accounts to rebuild the world's wealth - when the Ming Dynasty met investment bankers, the civil and military officials in the Ming Dynasty went crazy.
