Royal Guards is a terrible organization. Although their official positions are not high, they are similar to the departments directly under the emperor and have the function of supervising officials. Their words sometimes determine the future of a minister, even their life and death. In the era of Zhu Yuanzhang, officials really lived a life of white terror. With the security department, Zhu Yuanzhang knew what ministers ate and how many bowls they ate was terrible.
Under this system, many ministers also restrained their actions. In the era of Zhu Yuanzhang, there were few corrupt officials, which was inseparable from the security system. From this perspective, the Royal Guards have played a positive role. However, with the constant expansion of the power of the Royal Guards, ministers live in fear every day, not to mention making suggestions for national construction.
In his later years, Zhu Yuanzhang also saw the disadvantages of the Royal Guards system, so he abolished the Royal Guards before he died, and made it clear that his descendants were not allowed to use this system, so that their descendants could learn to be tolerant and learn to be patient. However, Zhu Yuanzhang's son Judy restarted the system after he ascended the throne and continued to supervise ministers.
