According to the second paragraph of Article 2 of the People's Police Law, the people's police include the people's police of public security organs, state security organs, prison management organs and judicial police of people's courts and people's procuratorates. Except for the above-mentioned departments and the people's police, no other department, institution or individual may hold or use the uniforms of the people's police and articles marked with the signs of the people's police, and no department, institution or individual may wear clothes similar to the uniforms of the people's police. The police uniforms, police titles and cap badges of the above five systems are exactly the same, and the police in various departments reflect the differences through the arrangement of armbands, police badges and alarm numbers. The police uniforms of the prison system wear the word "judicial" (this "judicial" refers to the "judicial administrative departments" such as the Ministry of Justice and the higher judicial departments of prisons rather than the judicial police) and the armbands and badges of seven digital warning signs. This is different from public security-the badge of local public security is the name of the province, the badge of the Ministry of Public Security and the badge of the units directly under the Ministry of Public Security are the Ministry of Public Security and the badge of professional police is the name of the industry. That is, "maritime detective" (customs anti-smuggling police), "aviation" (civil aviation public security), "traffic" (traffic department police, not traffic police), "railway" (railway police) and "forest" (forestry public security). The fine print of the armband is "Public Security" and the alarm number is six digits. The fine print on the badge and armband of judicial police is "court" and "procuratorial", and the alarm number is 6 digits like that of public security, but the arrangement is different-the first two digits of the alarm number of judicial police are provincial codes, while the name of the province has been written on the badge of public security, and the alarm number does not contain provincial information.
