The work of museum lecturers is mainly to provide services and explanations for visitors, including introducing the historical and cultural background of the exhibits. This kind of work is usually done by contract workers or temporary workers hired by museums, rather than staff of government agencies or institutions.

Career establishment refers to the establishment form of personnel working in government organs, institutions and institutions, which usually requires examination and selection, and has relatively stable jobs and career development prospects. However, the post of museum interpreter is usually flexible and can be adjusted according to the exhibition plan and visit demand of the museum, which does not meet the requirements of career establishment. Therefore, the narrator of the museum is usually not a professional editor.
