Over millions of years of geological tectonics and the thousand-year journey of our ancestors opening up the world has created Vietnam as it is today. Looking on the map, it is easy to see the Fatherland's border line with its majestic mountains and forests, like the spine of a giant dragon with mountain branches running towards the ocean, which are the ribs that form a shape of steady mountains and rivers. In each person's mind, the border is the corridor that limits the living space of the Vietnamese people.
