Jiànāng is a Chinese word, which means that a person is in good physical, mental and social condition. Health is the basic right of people and the first wealth of life. The traditional concept of health is "disease-free health", while the modern concept of health is overall health. The World Health Organization puts forward that "health is not only the absence of physical diseases, but also mental health, good social adaptation and morality". The English word for Health is: Wellness, and the English word for health/state is: health. In some dictionaries, "health" is usually simply and concisely defined as "the body is in normal operation without any disease". This is a traditional concept of health. Usually, we really regard the disease as a disorder of the body, which leads to the decline of function, the damage of quality of life (mainly physical pain) or premature death. In Ci Hai, the concept of health is: "All organs and systems of the human body are well developed, with normal functions, strong physique, full of energy, and good effects of labor and health food." It is usually measured by anthropometry, physical examination and various physiological indicators. "This formulation is more perfect than' health is disease-free', but it still treats people as biological organisms. Because although it puts forward the concept of "labor efficiency", it still doesn't treat people as social people. The understanding of health is recognized as correct in the era of biomedical model.
