15-Year-old Chen Yang is introverted and has mediocre sportsmanship. He became interested in the shot put during a physical education class. After that, he joined the school's shot-pulling team and encountered many difficulties in training. He also experienced setbacks in many competitions, including the pain of failure and injuries. However, with the encouragement of his teachers and his own persistence, he continued to break through himself, going from obscurity to winning the national championship, and finally entered a sports school to continue his shot put dream.
