" The Old Man and the Sea " was a famous novel written by Ernest Hemmingway. It mainly told the story of an old fisherman named San Diago. San Diago was an old fisherman. He lost his fishing boat during a long voyage, but he did not give up. Instead, he took an old dog and a young fisherman with him and began a long journey back to port. During the journey, they encountered many difficulties and challenges, but in the end, he managed to find his own fishing boat. However, he was too exhausted to go out to sea to fish alone. In the end, he fell on the beach and never got up again. This story was about a person's attitude and tenacity in the face of difficulties and setbacks, as well as their relationship of supporting and helping each other in adversity. At the same time, it also revealed the importance of the ocean and the fishing industry, as well as the insignificance and fragility of human beings in the face of nature.
