(HBO) - Hiding oneself at the foot of Bieu mountain, surrounded by old forests, Dao village of Sung hamlet in Cao Son commune (Da Bac) used to be a separate village from the outside. However, now Sung is one of the first four community tourism villages in Da Bac district attracting tourists to visit and explore. One day of experience in Sung hamlet, to have that strong transformation, for each Dao person here is not only a story of tourism but it is also an effort to step through the safe zone to successfully break through.
