What Appraises Position of Powerful Country?

How comfortably and harmoniously the people live in good health is an important yardstick of appraising the position of a powerful country.

Only when they have nothing to worry but lead a comfortable and harmonious life in good health, can their country be stable and all its affairs go well. When the people live in uneasiness and anxiety, both their families and society cannot be harmonious and, in the long run, strength and authority of their country will be weak. Therefore, a powerful one is a country in which all its people live a happy life in good health.
