"My good health is due to a soup made of white doves. It is simply wonderful as a tonic"

Chiang Kai-shek's quote suggests that he thinks that a soup made of white doves is responsible for his good health. He appears to be suggesting that the soup is a tonic, or a medical treatment, that has actually assisted him to preserve his health. This could be translated as a metaphor for the importance of nourishment and take care of one's health. It might also be translated as a literal statement, suggesting that Chiang Kai-shek has found a special remedy for his health. In either case, the quote implies that Chiang Kai-shek has found a method to keep his health, which he thinks the soup made of white doves is accountable for it. This could be interpreted as a pointer to take care of one's health, and to try to find special and creative options to illness.
