Setbacks and misfortunes are life's companions, but they are also life's wealth, which can sober people up and inspire them to forge ahead.
In the face of setbacks and misfortunes, pessimists see the impending death, while optimists see the turning point of life.
There is an old saying in China: God never shuts one door but he opens another. There is no despair in life, and it will get better under certain conditions. During the Spring and Autumn Period and the Warring States Period, Gou Jian, the King of Yue, became a prisoner. He earned enough strength and finally destroyed the state of Wu twenty years later.
In the face of setbacks and misfortunes, Gou Jian did not lose heart and did not give up. Finally, it ushered in a beautiful life in another village.
