When Zhu Yuanzhang ascended the throne. He knew exactly what kind of person Zhu Yuanzhang was, so Liu Bowen was wary of him even after his death, for fear that he would dig his own grave. As a result, his fears were proved to be correct. So he asked his descendants to put a clear law in his grave, which said that no one should rob or dig a grave. In this way, Zhu Yuanzhang was so guilty that he had to admit his mistake and repair the grave to make up for his mistake.
Because Hu had a grudge against him, he fabricated such a lie to slander Liu Bowen, which made Zhu Yuanzhang very angry. Because the process of his own promotion to this position is not very bright, he is also afraid that others will kill him by the same means, and Liu Bowen was also a talented person before his death, which makes him very worried. So he took advantage of Hu's words and sent people to dig graves. But I didn't expect to be anticipated by Liu Bowen in advance, and failed to achieve the goal, but made others laugh.
Even without Hu's advice, Zhu Yuanzhang, as a man, would still dig a grave, because he was not particularly generous and suspicious, and always suspected that others would deal with him, but no one expected that Liu Bowen guessed his move. That in the process of assistance, each other is very clear about each other's personality, so Liu Bowen left himself a posterior approach to avoid the decline of future generations. So choosing a monarch is really a lifetime thing. If you meet Zhu Yuanzhang, you may even die, so Liu Bowen is really wronged.
