Edison, a famous American inventor, taught himself tenaciously in order to realize his ideal. At home, when he learned carpentry from his father, his mother taught him to read. Edison was very diligent. At the age of nine, he finished The Rise and Fall of Rome and The History of England. Later, he studied physics and chemistry hard and became interested in scientific experiments. At the age of twelve, he worked as a newsboy on the train. He gets up at six o'clock every morning and doesn't rest until eleven o'clock in the evening. In order to make full use of time, he did an experiment in the turbulence of the train. As a result, a piece of phosphorus accidentally fell to the floor and burned instantly, which almost caused great disaster. He was so angry that the conductor slapped him several times. Since then, his ears have become deaf. However, he did not lose heart. For the sake of his ideal, he continued his tenacious exploration on the journey of science. He invented the electric light, telegraph, film, tram, telephone, storage battery, generator, phonograph and so on. And become the "king of invention."

When Lu Xun was young, he went to Japan to study medicine with the original intention of saving the country with medicine. In the second academic year, the school added a subject-bacteriology. When teaching this course, the shapes of bacteria are all shown in slides, and sometimes some current affairs slides are interspersed. Once after class, a documentary about the Sino-Japanese War was shown. There was a scene in which many Japanese watched a Russian spy and he would be beheaded,' while the people around him were physically strong but mentally numb. This made Du Xun particularly excited. He thinks that a man who is physically strong but mentally ignorant can only be a meaningless propaganda and spectator. Therefore, it is important to "cure" people's minds. Therefore, he resolutely abandoned medicine and followed the literature, using pen as a weapon to awaken national consciousness.

Ye Ting, the commander of the New Fourth Army with outstanding military exploits, was captured in the "Southern Anhui Incident" that shocked China and foreign countries. In the enemy's prison, he remained firm and unyielding in the face of threats and inducements from reactionaries, and wrote the immortal "Prison Song": "The door for people to enter and leave is locked, and the hole for dogs to climb out is open. A voice shouted: climb out and set you free! I long for freedom, but I deeply know how a person's body climbs out of a dog hole! I hope that one day, the underground fire will burn me even this living coffin. I deserve to live forever in fire and blood! "
