A: Ethics is a very important ideological training course, which can guide college students to form a correct outlook on life and the world. It is a compulsory course for aristocratic intellectuals. If there is no ethical theory as the criterion of our behavior, maybe we ourselves were confused that day and knew what was going on. As an outstanding representative of college students' intellectuals, they should be strict with themselves in personality, morality, thought and style, so college students must learn some ethical theories. I wish you success in your studies, become a veritable college graduate and become a social elite.
