How many years did it take from the second senior sheriff to the first high school?

Promotion below Senior Superintendent II requires two years' service; Senior Superintendent II needs three years' service to be promoted to Senior Superintendent I; The first-class senior police sergeant is promoted to the second-class police Commissioner, and the second-class police Commissioner is promoted to the first-class police Commissioner, who needs to serve for four years.

The second-level senior police chief of the Municipal Public Security Bureau is equivalent to the director level, and the police ranks are divided into: first-level senior police chief, second-level senior police chief, first-level police chief, second-level police chief, third-level police chief, first-level police officer, second-level police officer, third-level police officer, fourth-level police officer, junior police officer and trainee police officer.

A first-class police inspector is usually a section chief or deputy section chief. The administrative level of the frontline units of law enforcement duty is low, so the state implements the policy of post reform to improve the administrative level of the police. As the administrative level rises, so does the police rank. Public security is different from ordinary civil servants. They have an independent hierarchy. The rank and salary of the police are one or two grades higher than those of civil servants in other government departments. Therefore, they cannot be narrowly compared with the administrative ranks of civil servants, and they cannot be completely separated from the administrative ranks of other civil servants. Judging from the analysis of the ongoing reform, the rank of the second-level sheriff is similar to that of the first-level civil servant.
