Because this is the stumbling block that Zhu Yuanzhang created for the overbearing Shen Wansan. Shen, an extremely rich man, has felt that there is nothing in this world that he can't afford. This is aimed at the abyss of such a rich man.

If Shen Wansan had been modest, if Shen Wansan had been low-key, if Shen Wansan had reacted …

Unfortunately, there is no if.

This thing is like this. Zhu Yuanzhang just rebelled and successfully ascended the throne. Naturally, we should circle our country and build a good wall. First, I am afraid of another war, and this dilapidated city wall is already vulnerable; Second, at least one country's walls look passable when they are built. There is a saying that building a wall to accumulate grain is widely circulated. But the treasury was empty and there was not much money, so Zhu Yuanzhang called the rich leader Shen Wansan.

With a wave of his hand, Shen Wansan increased the cost of repairing the city wall by a third. Well, Shen Wansan is a businessman, but he is already rich, so he wants some fame. After the city wall was repaired, he wanted to enter the palace to ask Zhu Yuanzhang for credit, and even wanted Zhu Yuanzhang to approve the city gate to be named "Jinbaomen" after his idea. Zhu Yuanzhang was a little annoyed at this time, but Shen Wansan felt that he had done Zhu Yuanzhang a favor and could be regarded as Zhu Yuanzhang's benefactor. He said in the tone of a local tyrant, if it is because the money is not enough, I can add more money.

But what Zhu Yuanzhang thought was that I didn't even reward the three armed forces. Are you trying to turn it upside down and climb on my head? So I gave him the official usury, gave him a penny and said, "You help me collect the interest on this penny, and one penny will be changed into two, and two pennies will be changed into four, and then give it to me one month later."

But this loan shark ... needs to pay back more than 500 million after 30 days ... Who can stand it?
