Without wind and rain, there would be no maturity of autumn fruits; Without the biting wind, there would be no tenacity of pine and cypress. In adversity, don't blame others blindly, but think more about how to overcome difficulties. Peterson said: "In life, there are often countless blows from the outside world, but the final decision is in your own hands."

Adversity gives people valuable opportunities for tempering. Only those who can stand the test of adversity can become truly strong. Great men at all times and in all countries struggled out of adversity with indomitable spirit. Beethoven, who was deaf, trudged on the black and white keys covered with thorns, knocked on the sacred door of fate with his fingers, and made a brilliant movement in which musicians struggled tenaciously against bad luck. Sima Qian endured the pain of castration and completed the historical masterpiece Historical Records. Zhou Wenwang was detained and played Zhouyi. "Heaven will descend to the people of Sri Lanka, and they must first suffer their minds and work hard." Therefore, adversity is a stepping stone for the strong to climb the peak and an abyss for the weak to go to destruction.

Some countries in Europe and America deliberately turn straight roads into detours. The high cost of road construction and driving time are really "asking for trouble" for Europeans and Americans who have economic minds and regard time as money. But they think it is worthwhile, because speeding on a straight road without any obstacles for a long time can easily paralyze people and lead to traffic accidents. With the obstruction of corners, drivers must always be vigilant and dare not take it lightly. Facts have proved that their approach is wise.
