Police or public security. Maintaining public order is called public order, and police also means public security. A few countries in the world, including China, are generally called "police" internationally. There is no substantial difference between "police" and "public security", and there are various historical and practical factors leading to the parallel situation of the two names. The name "public security" first appeared in the history of * * * in February 1939. In order to be different from the police organs of the puppet regime in name, the Decision on the Establishment of the Ministry of Social Affairs issued by the Central Secretariat requires the establishment of public security bureaus or security offices in all border areas and public security bureaus in all counties. After the founding of People's Republic of China (PRC), the first national public security conference held in June 1949 10/5 decided to use the name "public security". After the reform and opening up, due to the adjustment of the functions of relevant institutions, international exchanges, contacts and other reasons, the title of "police" began to be restored on some occasions and quickly popularized until the People's Police Law promulgated by 1995 was confirmed in legal form. Because the law clearly stipulates that "public security" is only used in the name of the organization, the accurate address of the individual members of the public security organs should be "police", and "public security" and "public security personnel" are not standardized. Even if the name of the organization is understood literally, the name "police station" seems to be more intuitive and easy to understand than "public security bureau", which can avoid vocabulary barriers in communication, especially in international communication; It is also more logical. Public security of the whole society (including social order, public property, civil rights, etc.). ) means the same as "police" or "maintaining public order". Maintaining public order is called public order, and police also means public security. A few countries in the world, including China, are generally called "police" internationally. The public security organ is an important part of the government and an administrative organ of the state. At the same time, it is responsible for the investigation of criminal cases, so it is one of the judicial organs of the country. Public security organs are the functional departments of the government, which manage social order according to law and exercise state administrative power. At the same time, public security organs investigate criminal cases according to law and exercise the state's judicial investigation power. The nature of public security organs is twofold, that is, both administrative and judicial. The duties of public security organs (police) are: to prevent, stop and investigate illegal and criminal activities; Preventing and combating terrorist activities; Maintain public order and stop acts that endanger public order; Manage traffic, fire fighting and dangerous goods; Manage household registration, citizen identity card, nationality, immigration affairs and foreigners' residence and travel in China; Maintaining public order in border areas; Guard the specific personnel specified by the state and guard the important places and facilities; Manage assemblies, processions and demonstrations; Supervise and manage the safety supervision of public information networks; Guide and supervise the public security work of state organs, social organizations, enterprises and institutions and key construction projects, and guide public security committees and other public security organizations. The difference between public security and police: Public security is a kind of police, including public security, judicial police and national security police. (People's police include the people's police of public security organs, state security organs, prisons and reeducation-through-labor administrative organs, and the judicial police of people's courts and people's procuratorates. ) The name "public security" first appeared in the history of China * * * in February 1939. In order to be different from the police organs of the puppet regime in name, the Decision on the Establishment of the Ministry of Social Affairs issued by the Central Secretariat requires the establishment of public security bureaus or security offices in all border areas and public security bureaus in all counties. After the founding of People's Republic of China (PRC), the first national public security conference held in June 1949 10/5 decided to use the name "public security". After the reform and opening up, due to the adjustment of the functions of relevant institutions, international exchanges, contacts and other reasons, the title of "police" began to be restored on some occasions and quickly popularized until the People's Police Law promulgated by 1995 was confirmed in legal form. The second paragraph of Article 2 of the Law defines the scope of the people's police, that is, "the people's police include the people's police of public security organs, state security organs, prisons and reeducation-through-labor administrative organs, as well as the judicial police of people's courts and people's procuratorates". It can be seen that all members of the public security organs belong to the people's police. From the legal point of view, because the law clearly stipulates that "public security" is only used for the name of the organization, the exact name of individual members of the public security organs should be "police", and "public security" and "public security personnel" are not standardized. Even if the name of the organization is understood literally, the name "police station" seems to be more intuitive and easy to understand than "public security bureau", which can avoid vocabulary barriers in communication, especially in international communication; At the same time, it is more logical and can accurately define the connotation of this group composed of many people's police individuals with different functions and responsibilities.
