Generally speaking, deputy section chiefs assist section chiefs in carrying out their relevant duties and work under the leadership of the section chief. If a person serves as both Deputy Section Chief and Section Chief at the same time, it may lead to problems such as unclear responsibilities, overlapping or conflicting work.
Additionally, organizational bodies usually have clear delineation of duties and hierarchical settings for cadre positions to ensure the standardization and effectiveness of management work. If a person serves as deputy section chief and section chief at the same time, this principle may be violated, leading to confusion in management.
Of course, there may be individual cases where a person serves as both a deputy section chief and a section chief under certain special circumstances, but this usually exists only in a specific organizational structure or under a special working environment.
Thus, in general, a person cannot serve as both Deputy Chief and Chief of Section.
