In the vast ocean, a weak sardine is chased by a huge whale, which makes people secretly worry about the fate of sardines. However, when the whale looked at the beach, it knew that it had lost, not because of courage and strength, but because it didn't know to give up. People are a group with wisdom, and people can use wisdom to pursue their own success. However, people are sometimes tempted by things in front of them, so they are blinded by interests and just blindly "desperately", and the result can be imagined. Chu and Han contended, and many heroes lit up the starry sky of history. Han Xin's ending is the saddest. Xiao He overtook Han Xin in the next month, giving him enough space to show his talents on the magnificent historical stage. "Ambush on All Sides" and "Embattled on All Sides" ... Xiang Yu suffered repeated battles and defeats, which witnessed Han Xin's great talent and greatness. And Han Xinye returned home dressed in gold, won one victory after another and was promoted again and again. Being a prince is world-famous. But Han Xin didn't stop there, just like a greedy sardine kept shaking in front of him, making him forget the danger of being stranded, so that after the throne was overturned, he was upset and even wanted to take risks. In the end, the lack of "giving up wisdom" brought him a fatal disaster. Perhaps, when Han Xin saw the "beach" of death, he would suddenly realize. Originally, his literary talent was not as good as the wisdom of giving up in time. On the contrary, some people are not. Gou Jian, an outstanding King of Yue in history. Under the strong influence of the king of Wu, he chose to give up his personal dignity. His abandonment brought about the growth of Yue State, and finally made him destroy Wu State and become one of the great powers of that period. This is a kind of wisdom that knows how to give up at the right time. Giving up does not mean not pursuing; Pursuit does not mean not giving up. Pursuit can achieve a lifetime, and it can also be ruined if you don't give up. If you know how to sail at the right time, such as whales, when the sea is getting shallow, "give up" chasing and turn around and swim into the sea, then what people enjoy in the deep blue and rootless sea is not the beauty of life?
