Dixon was doing experiments when he was working on the train. Once he accidentally knocked over chemicals and set the train on fire, which made the conductor deaf. But he still studied hard and continued to do experiments. Does he study to get grades? He just wants knowledge and goes to school. As a result, he got a lot of knowledge about inventions, not achievements.

Confucius, a teacher for generations, is extremely knowledgeable, so many students ask him to study. Do they want grades? No. They pursue truth more than learning. Confucius and his students do not seek achievement, but seek the truth of life.
