Why do old policemen always have two bars and three bars?

Upstairs is wrong. 2 bars and 3 bars are the highest police rank that ordinary police can reach, the highest is the white line, and the lowest is 1 wheat 1, which is the police rank that needs to be held. Generally, only the deputy bureau level can achieve it, that is, the county-level public security bureau chief can achieve it. If you don't serve, the police are at most a supervisor, with two bars and three bars. Old policemen who have worked for many years can generally be promoted to 2 bars and 3 posts, but they can enjoy formal treatment and retire.

The rank from low to high is generally superintendent, with one bar as superintendent, two bars as police inspector, Mai Sui as police chief, the national emblem divided into commissioner general and Deputy commissioner general, and commissioner general as minister of public security.

At present, China has begun to carry out the reform of police rank, and the new four-long-three-member system is a four-level sheriff and a three-level police officer. You can check it again.
