Human health refers not only to normal body, but also to normal and psychologically healthy personality. Traditional education in China has advocated the cultivation of "healthy" people since ancient times. Here "constitution" refers to a person's body or constitution, and "spirit" refers to a person's spirit, psychology or character. It is important for a person to have a healthy body or a strong body, but it is also important to have a healthy mind or a sound personality. In a word, only people with sound constitution are truly healthy. To meet the requirements of "health", it is not enough to talk about physical hygiene alone, but also about mental hygiene.
