Hạ Long Bay is located in northeastern Vietnam. According to local legend, when the Vietnamese were fighting Chinese invaders, the gods sent a family of dragons to help defend the land. This family of dragons began spitting out jewels and jade. These jewels turned into the islands and islets dotting the bay, linking together to form a great wall against the invaders. The people kept their land safe and formed what later became the country of Vietnam.
After that, dragons were interested in peaceful sightseeing of the earth, and then decided to live here. The place where the mother dragon descended was named Hạ Long, the place where the dragon’s children attended upon their mother was called Bái Tử Long island (Bái: attend upon, Tử: children, Long: dragon), and the place where the dragon’s children wriggled their tails violently was called Bạch Long Vỹ island (Bạch: white- color of the foam made when Dragon’s children wriggled, Long: dragon, Vỹ: tail).
