According to the inquiry of Health World Network, in 1973, Michaela Lund, Minister of Health and Welfare of Canada, first put forward the concept of "health promotion", educating and supporting individuals and organizations, so that they can accept more responsibilities and participate more actively in matters that can affect their physical and mental health. It is emphasized that a person's health is not only the responsibility of the hospital, but also the idea that the individual must invest. The environment, city and society he lives in must also be promoted through education and health.
