Historical reasons
The post system was first introduced in the Qing Dynasty, and then began to be used at the beginning of the founding of New China. However, the evaluation and employment system of primary and secondary school teachers' professional titles was formed after the reform and opening up, which started late and is difficult to integrate with the post system.
Teachers are different in nature.
Judges are professional legal workers, and their professional level and execution are crucial to judicial justice. Although primary and secondary school teachers also have the professionalism of loving their jobs and serving the people, their main duty is to provide educational services for students, which has little impact on maintaining social justice and national security.
The system of professional title evaluation and employment has been gradually improved.
With the country's investment in education increasing year by year, the evaluation and employment system of primary and secondary school teachers' professional titles has been gradually improved, and the rank division of similar post system has been gradually realized.
Scope of application of postal system
The post system is a rank system, and its implementation needs to consider many factors, so we can't simply generalize all kinds of occupations.
