In the process of confrontation between the emperor and his ministers, the emperor required a secret service organization that served him and was above the existing system. Such an organization would help him monitor his officials and enhance control over his subordinates. Besides, the ruler could also control the military and political affairs more closely through the Changwei, understand the public sentiment, prevent or forestall those activities with improper intentions. Ultimately, this would serve the purpose of maintaining his feudal rule. This emergence of secret service organizations in feudal society was, therefore, an inevitable development. The Changwei system was created to adapt to the feudal authoritarian political system, and its impact on the social, political, economic and judicial system at that time was significant. This is also a historical lesson for China, which is now building socialism with its own characteristics. The serious consequences caused by the destruction of the judicial system through Changwei serve as a reminder of the significance of today’s laws, highlighting the importance of legal authority and stability. Moreover, the negative impact on the economic environment at that time underscores the wrong approach to economic development. In addition, the Changwei system’s role also emphasizes the importance of building a clean and transparent political environment.
