We have been inspired by our parents and teachers since childhood to be admitted to college. However, when we passed the high school entrance examination and college entrance examination and came to the university we once dreamed of, everything was so unsatisfactory. Maybe this is not the university we like, and you will be dissatisfied with its environment; maybe you will not get along well with your roommates, and a series of conflicts will arise; maybe you are no longer that interested in the major you chose before, and you no longer even want to take professional courses...

If it happened once, would you still cherish your three years in college?
