In Chinese, there are two interpretations of Safety and Security in English.

Safety in Chinese is a generalized Safety, which includes two meanings: one refers to the safety of natural attributes or quasi-natural attributes, which corresponds to the safety in English; the other refers to the safety of social humanism, that is, the safety 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 human beings; The destruction of social humanism is mainly caused by the purposeful participation of people. Therefore, broadly speaking, Security should include two meanings of Safety and Security, and we often say that the security guard mainly refers to the narrow sense of security, foreign countries are usually called "security".
