Starting from Hong Kong, Wandering Around the World

After watching it for a while, I couldn't stand it anymore. I didn't feel immersed in it. I gave it a Hong Kong look, but the world background, customs and customs didn't have a Hong Kong flavor. The most basic setting is that the protagonist is a police officer. The author may not even understand the hierarchy and division of labor of the Hong Kong police force. It's okay for the protagonist to be in plainclothes and write about arrests and interrogations. But later it was said that the job is to patrol the streets, and patrolling the streets is a job in military uniform. Is the protagonist in military uniform or in civilian clothes? The division of labor among the Hong Kong police is unclear. There is also an independent office where the protagonist's boss is the police chief. If they are in military uniform, the police sergeant also patrols the streets, and is usually a team leader. If they are in plain clothes, the team leader is usually a trainee inspector or inspector, and the police sergeant is at most a deputy, without an independent office. There is also a police chief who gives the protagonist a promotion? ? He himself is a low-level person, is it his turn to draw the cake? He doesn't even have the qualifications to recommend promotions. At most, the inspector reports to recommend people for promotion and asks him about the performance of the people being promoted during the review. Not to mention greeting other police stations, who knows him?
