The spirit of the first and third college students who have the courage to sacrifice themselves and save others is very admirable. They carry forward the socialist core value system with their own actions, which is conducive to the construction of a harmonious society. Second, three college students sacrificed themselves to help others. We are deeply moved by them and feel sorry for the loss of their young lives. In order to avoid this kind of thing from happening again in the future, some managers and enterprises should make safety warnings in dangerous places, such as warning signs and warning slogans, to remind others to stay away from dangerous places. Third, our society and schools should strengthen safety awareness education through various forms to improve the safety awareness of all walks of life and reduce the occurrence of life-threatening things.
