According this article http://getoffthetrail.com/2012/03/02/how-to-have-a-pleasant-journey-in-vietnam/, i know most of the thing is true and it is not easy for me, because I’m Vietnamese.
My opinion is everywhere in the world when you arrive there like a tourist you will get some same experiences like Vietnam. May be less than Vietnam but it still exists.
One thing i don’t like when i go to travel in Vietnam is the beggar and sale on the street. They are bother me a lot and especially the toilet is one of the problem for traveler.
