Truth is often in the hands of a few people, which conforms to the scientific principle of dialectical materialism. Marx told us: "There is no smooth road to science. Only those who are not afraid of hard work and climb on steep mountain roads can hope to reach the glorious peak. " Among many people, those who master the truth are those who study hard and have the courage to innovate, especially those scientists and inventors. After all, these people are a minority in the population. In addition to their own health and intelligence, it is more important for these people to explore and discover in practice, which is difficult for ordinary people and most people to do. 1600, Bruno, a famous Italian astronomer, was beaten into a heretic by the church for opposing Copernicus' geocentric theory and supporting Copernicus' Heliocentrism, and was burned alive in Rome's Flower Square on March 17 of that year. Later historical practice proved that Bruno's views and propositions were correct, and the truth was in the hands of a few people.

During the Cultural Revolution in China, most people blindly obeyed the movement, while in Liaoning, China, one person opposed the movement. She was a martyr in Zhang Zhixin who was rehabilitated after the Cultural Revolution. Practice has proved that her view is correct, and the truth is in the hands of a few people. Li Siguang, a famous geologist in China, founded geomechanics, which provided a scientific basis and laid a theoretical foundation for earthquake prediction and oil exploration in China. Practice has proved that Li Siguang's theory is correct and the truth is in the hands of a few people.

Therefore, to respect talents, we must attach importance to their scientific discoveries and inventions, and let the scientific truth mastered by a few people become the driving force for social development and progress.
