The word "hospital" comes from Latin, which means "guest", because when it was first established, it was for people to take refuge and have a lounge, which made people comfortable and entertaining. Later, it gradually became a professional institution to meet human medical needs and provide medical services, and it was a service place to accommodate and treat patients.

Hospital refers to a medical institution that provides necessary medical examination, treatment measures, nursing technology, consulting services, rehabilitation equipment, rescue and transportation services for patients with the main purpose of saving lives in accordance with laws, regulations and industry norms. Its clients include not only symptomatic patients and wounded, but also elderly people who cannot take care of themselves or have limited activities and rely on medical care. Forensic medical experts assess serious patients who are dependent on medical treatment or whose condition is unstable and need long-term rehabilitation and regular observation and examination, or have other specific situations and groups, such as healthy people (such as pregnant women, parturients and newborns) and completely healthy people (such as people who come to the hospital for physical examination or oral cleaning).

Originally set up for people to take refuge, there are entertainment programs to make them comfortable and entertaining. Later, it gradually became a specialized institution for receiving and treating patients.
