First of all, the director of the provincial public security department can't be a third-level police inspector, and the police rank stipulates the main hall level and the first/second-level police inspector. The provincial public security department is a departmental unit, and the director awards the first-class police chief; Now, according to the requirements, the deputy governor in charge of politics and law (specifically, the government deputy, mainly to make the level of the top leaders of the public security organs equal, because the public security organs are deputy ministerial level, such as the provincial procuratorate, and the provincial law is deputy ministerial level) also serves as the public security bureau chief, so the public security bureau chief is a deputy ministerial level and is awarded to the deputy director general. As Qingdao is a sub-provincial city (Jinan is also a sub-provincial city), the secretary of its municipal party committee is at least concurrently held by the Standing Committee of the Provincial Party Committee, and the four major teams are deputy ministerial level. Except for the four major teams, the Standing Committee of the Municipal Party Committee and the four major teams are all at the main hall level. The units directly under the municipal government (municipal bureau, municipal district) are deputy departmental units, so Qingdao Public Security Bureau is a deputy departmental unit, and the director is awarded the second-level public security director. Similarly, the deputy mayor in charge of politics and law (also a member of the party group of the municipal government) is the director of the public security bureau according to the regulations, and is the main hall level, so it is normal to award the first-class public security bureau chief, which is not out of line at all. You should know that this is not casual, and there are rules for customs clearance. Secondly, you said that the director of Jinan is the second-level public security director. If the vice mayor is not part-time, he is a CPC and a second-level public security bureau chief. At present, they are all vice mayors, holding official department-level posts, but the promotion of the first-level public security bureau chief requires not only rank posts, but also time, such as serving as the second-level public security bureau chief for two years, serving as the official department-level public security bureau chief for four years and working for 25 years. According to what you said, he may not meet the time requirement. In this regard, please refer to Yan Xijun, Sui Ruwen and Zhang (2022 10), three consecutive police chiefs in Qingdao. The latest news photo released by Qingdao is the deputy mayor of Qingdao, the party secretary, director and inspector general of the Municipal Public Security Bureau, but it is still the second-class police rank. After being confirmed as the deputy mayor of Qingdao, a member of the party group of the municipal government, the party secretary, director and inspector general of the municipal public security bureau, he was still the second-class police rank, and it took a year or two to be promoted to the first-class police rank.
