Sense of Security
In the duty room of the police station, the newly arrived Xiao Li sits upright. On the table in front of him is a brand-new "Duty Officer Regulations."
The most prominent rule on the regulations is: "When members of the public come for consultation or help, the duty officer must say the four words 'I am a police officer,' and the tone must be firm and full of strength, so as to enhance the public's sense of security."
