The promotion channel is not smooth. According to the "Opinions on Establishing the System of Grade Promotion of Managers in Institutions below the County Level" and other documents, the promotion of career establishment personnel is generally carried out within the scope of career establishment promotion and cannot be carried out beyond the nature of establishment. For example, a general cadre with professional status (grade 9 staff) who has worked in a grade 9 management position or a grade 9 staff position for more than 4 years can be promoted to a minor course (grade 8 staff), but not directly to an administrative minor course.
