"People tend to study overbroad to get knowledge in lieu of attending in Vietnam universities. Do you agree or disagree with this statement? Why and why not?"  I see that is a very good statement but not accurate.
Firstly, there is no truth:

People who want to gain more understanding first need a solid foundation. For some people, taking the time to study at a university is not necessary. But for me, the university is like a library with a system that has been distributed information clearly and selectively.

 Today's society, not just learning something too much will have good results, but how to process and filter information. What's necessary for yourself is to use that new fastest way to gain knowledge.

On the other hand, the university is a major focus of knowledge. Good people will sit together to build and spread useful information, so why not choose the university as a place to cultivate knowledge? Selectively intelligent learning is the truth. And those advantages have somewhat appeared in the universities. Therefore, the shortest way to receive infinite knowledge of the world originates from the university. A place that is condensed enough for the knowledge you need to use and develop later.
