Main student cadres refer to 1. Class: deputy secretary of the Party branch, deputy secretary of the Youth League branch and deputy monitor (note: deputy class cadres are generally not considered as the main body of student cadres). 2. College and university level: deputy secretary of student party branch, propaganda member, organization member, disciplinary member (or disciplinary Committee member) and other members or above (some schools only set up party branches at college or department level, not in classes); As deputy secretary of the Communist Youth League branch, deputy ministers of various ministries and other positions above the deputy department (or other positions equivalent to the deputy department), as vice chairman of the student union, vice chairman and other positions above the deputy department (or other positions equivalent to the deputy department), as the personnel above the deputy department of various legally registered societies in schools. Hold the post of deputy minister or above in student organizations officially recognized by other schools. The second question: generally speaking, it refers to those who hold the post of deputy minister or above in various legally established student organizations, such as chairman, vice-chairman and deputy minister. We think these people have higher positions than the monitor and the secretary of the League branch.
