Recently, an increasingly number of young adults tend to have vocational trainings, while the others choose to pursue their higher education in universities. Obviously, people will gain more professional knowledge and specific trainings, as well as have an income, while working for a company. However, one of the main disadvantages is that they might face difficulties of getting promotion without a higher degree certificate from a university. In my opinion, young people having on-the-job trainings at work is still much more beneficial than learning in universities.
