Personally, I feel that the problem of dealing with corruption in the Ming Dynasty is bound to fail. Zhu Yuanzhang's attack on corruption is absolutely powerful, but he ignores the fact that officials are human beings and have all kinds of reasonable material needs, such as eating and drinking Lazar, being sent to weddings and funerals, and supporting his wife and children. Throughout the Ming dynasty, especially in the early days, the legitimate income of officials was very low, and there was no institutional supervision over power and officials. Only rely on the secret service to supervise officials at all levels, and this supervision is based on whether they are loyal to the imperial power. Unless they are insatiable, spies will not really touch those "politically correct" corrupt officials.
Imagine asking a hungry person to take care of a pile of steamed buns without supervision. Who wouldn't steal it? As a result, officials at all levels can only find other income channels besides wages. Honest people will make some gray income, and dishonest people will be greedy directly.
This is my comprehensive feeling about the history of the Ming Dynasty. It's hard to provide data, so make everyone laugh.
