The secretary of the municipal party committee and the mayor of prefecture-level cities generally belong to the main hall level (individual cities are deputy hall level), but the secretary of the municipal party committee is the head of the party and the masses, and the mayor is the head of the government. Although the level belongs to the main hall class, the level of the party secretary is slightly higher than that of the mayor, because in the party position, the mayor is generally the deputy secretary of the municipal party Committee, and the deputy secretary of the municipal party Committee is obviously not as high as the secretary of the municipal party Committee. The secretary of the Political and Legal Committee of prefecture-level cities generally ranges from the deputy department level to the main department level in administrative duties, and is subordinate to the secretary of the municipal party committee and the mayor.
