vietnamese people are very friendly,that is why when tourists from every corner in the world come to visit vietnam are all greeted with a sentence " hello..ONG TAY" by children. that mean "HI, SIR/MADAM FROM WESTERN AREAS". it's a litter bit funny but it true. come to visit HALONG you are not only visiting the beautiful landcapes but also exploring the customes,cultural or enjoy some local products. being a local, I'm a person who know every corner of the city, but sometime I get stuck with foreigners because they can find out even some special things that I feel nothing about it when I see it everyday....it's strange!:D
