Security in Chinese has two interpretations in English: Safety and Security. The modern advanced English Chinese dictionary published by Oxford University mainly explains the word Safety as: safe, safe, secure, safe (lock), safe (box), etc; The main interpretation of the term Security is: security, no danger, no worry, providing safe things, making safe things, collateral, collateral, security (police), security (troops), etc. Security in Chinese is a kind of security in a broad sense. It has two meanings: one is security of natural or quasi natural attributes, which corresponds to Safety in English; the other is security of social humanity, that is, security with obvious artificial attributes, which corresponds to Security. The destruction of the security of natural or quasi natural attributes is not mainly caused by the purposeful participation of people; The destruction of social humanity is mainly caused by the purposeful participation of people. Therefore, in a broad sense, security should include two meanings: Safety and Security. What we often say is security in a narrow sense, which is usually called "security" abroad.
In the West, the concept of loss prevention and crime prevention is used instead of the word "security". Just like Chinese security and prevention are used together to form a new compound word in the West, Loss Prevention and Critical Prevention are also used together. Loss prevention and crime prevention constitute two aspects of safety/security. beyond seas, Loss Prevention usually refers to the focus of the social security industry, while Crime Prevention is the focus of the police law enforcement department. The organic combination of the two can ensure social stability and security. In this sense, loss prevention and crime prevention are the essential contents of safety precautions. To sum up, security is not only a public security business (police executive department), but also a social public undertaking and socio-economic cause. Their development and progress not only depend on the development and progress of science and technology, but also provide and create a good social environment for the progress and development of science and technology. Safety is a major concern of the whole society, so security is a work that all industries, especially high-risk industries with potential dangers, must pay attention to. The security work of various industries is managed by different departments. For example, the State Administration of Work Safety is in charge of the work safety of enterprises in China. Public security prevention shall be jointly managed by the public security department and social forces. Medical related security is managed by the Ministry of Health and other institutions.
