Nowadays, serious ethical problems have occurred in many engineering fields around the world, and this cruel reality calls for ethical education. Engineers must put the“Safety, Health and Happiness”of the public at the first place. Engineering practice is not only a skill, but also a virtue. It is particularly important for engineers to have good abilities of“Ethical cognition, Ethical judgment and Ethical decision-making”. Engineering ethics is to“Control technology with Tao and Integrate technology with Tao”and to carry forward the spirit of rationality. They need to understand the relationship between“Jurisprudence, Reason and Ethics”well. When completing the project, they should achieve the harmonious coexistence between“People and People, People and Society, People and Nature”. Most importantly, the idea of“People-oriented”should be based on“Life-oriented”.
