Note: worry: sadness and evil. Happiness: ease and enjoyment. Sad and difficult circumstances can make people strive to survive, and a comfortable and happy life can make people slack off and lead to extinction. Always be vigilant to prevent evil.

Being in trouble can make a person or a country survive, and being at ease can make a person or a country perish.
