The situation you mentioned does exist in the society and is quite common, but we should see that it is not their fault, but the mistakes in education and social values of the whole society that led to this result. College students are still relatively simple, with little contact with society, serious idealism, self-righteousness or lofty.
The best way is to make them understand after encountering setbacks in practice. Therefore, freshmen should first do a good job in frustration education, give guidance and help, give them a burden, give them encouragement, and get better slowly.
Of course, college students' impetuousness also exists, so we need to give them some time!
