It depicts an old fisherman named Santiago who caught a huge marlin after many hardships, but was finally devoured by sharks, leaving only a fishbone. This novel has deeply impressed me with the unpredictability and uncertainty of life.

In the novel, Santiago is an extremely brave person who is not afraid of difficulties and is determined to catch the big fish. He is a lonely old man with no family or friends, only himself and the sea. In the process of fishing, he demonstrated his perseverance and wisdom, approaching his goal step by step. However, when he finally caught the fish, he was attacked by sharks, leading to his failure. This ending made me feel the unpredictability of fate and the uncertainty of life.
