Sima Qian, a historian of the Western Han Dynasty in my country. He had been subjected to a shameful castration, but he was not depressed by it. In prison, he relied on his strong will and tenacious perseverance to fight against hardships, and finally went through all the hardships to write "Historical Records", the "historian's swan song", and became a famous historian in our country. Suffering is a kind of wealth for Sima Qian. Li Bai, the great poet of the Tang Dynasty, was depressed and frustrated throughout his life. His ambition of "securing the country and benefiting the people" could not be realized. He was frustrated in his official career and was often excluded. Faced with this kind of suffering, he did not sigh or complain. In the uninhibited manner of "laughing up to the sky and going out, how can we be the people of Penghao?", he drank freely and splashed ink; ", which makes me unhappy", holding the wine in the wind, and the long sword roaring into the sky. A generation of poetry immortals was born out of nowhere. His name will last forever and he will be admired by all generations. For Li Bai, suffering is his wealth. Although we are still arrogant about everything, even though we are as fragile as before, afraid of failure and setbacks. But if you think about it carefully, life cannot be smooth and smooth. If that were the case, life would appear monotonous. Only the addition of suffering and setbacks can add beautiful color to the white paper of life. It is precisely because of the existence of suffering and the alertness of setbacks that life appears colorful and realistic. Therefore, suffering is a rare treasure for each of us.
