Mencius was born in sorrow and died in happiness. There is such an interesting and thought-provoking experiment. If a frog is accidentally thrown into a boiling oil pan, the frog can unexpectedly jump out and escape from the trap. territory. Then the same frog was placed in a pot of gradually heated water. This time it felt so comfortable that when it realized the danger was coming, it was too eager to jump and finally died at the bottom of the pot. From this experiment, we can see that frogs are sensitive to immediate dangers and slow to respond to dangers that have not yet arrived. From this, I thought of people. In fact, people are also like this in this regard. As Mencius said: "Born in sorrow and died in happiness." In the journey of life, adversity reminds people to be vigilant and inspire people to forge ahead, but the comfortable and superior environment does not. It wears down people's will, makes them indulge in happiness and comfort, and often accomplishes nothing. Some people even indulge in drunkenness and self-destruction in their comfortable moments. This is very similar to a frog leaping up when faced with danger and lying down waiting to die in warm water. "Born from sorrow" is an eternal saying. The story of King Gou Jian of Yue in the Spring and Autumn Period is the best example of it. At that time, Gou Jian surrendered and sued for peace. He humbled himself to serve Wu and endured hardships. After "ten years of gathering together and ten years of training", he finally turned from weak to strong, raised an army to destroy the state of Wu, and became the overlord of his generation. How could Gou Jian recover? This is the result of the worry and humiliation of national subjugation that made him angry and urged him to rise up. This shows that when there are many difficulties and there is no way out, people can often show extraordinary perseverance, unleash their unexpected potential, fight their way out of the siege, and carve out a way out. However, when there is a way of life and comfort, people often fail to grasp it well and "die of comfort". The best example of this is Chuang Wang. In the spring of 1644, King Chuang invaded Beijing, thinking that the world was settled and he was done. The new bureaucrats who were born from peasants have lost all their all-powerful spirit in conquering the world during the uprising. They only want to enjoy peace and happiness in Beijing and "celebrate the New Year every day." Li Zicheng wants to become emperor as soon as possible, Niu Jinxing wants to be the prime minister of peace, and the generals want to create Mansion. When the Qing troops entered the pass and the Ming Dynasty armed forces came back, the rebel army was completely defeated. This reminds me of Ouyang Xiu's old saying, "Sorrow and labor can rejuvenate a country, and leisure and leisure can destroy one's life." When dangers arise, people can open their eyes and fight hard, so they can turn dangers into disasters; but in the midst of ease and enjoyment, their will fades and their energy is gone, resulting in a complete defeat.
