This is a political paper with a preface. In view of the social situation that corrupt officials were all over the world and class contradictions were increasing in the middle Tang Dynasty, the author put forward the progressive view of "officials for the people". He believes that people and officials should be employed and employed, and the relationship between master and slave. Officials must "go out early and return late, be diligent and work hard" in order to achieve "fairness in litigation and fairness". If officials are passive, even corrupt, accept bribes and practice favoritism, the people have the right to punish and dismiss them as incompetent slaves. Although this kind of political ideal is an unattainable subjective imagination in the feudal society under the dictatorship of the landlord class, it reflects the people's strong desire and is a precious material in the history of political thought development. The article begins with farewell, ends with farewell, and discusses the management of officialdom with farewell in the middle, echoing from beginning to end and closely following the title. The metaphor of "serving the officials for the people" is reasonable and has excellent opinions.
